Sl. 3: Rad prekidača sa 3 pozicije

Režim rada Radna osovina formira jednu jedinicu zajedno sa 3 nožasta kontakta. Zbog rasporeda

fiksnih kontakata (zemlja - sabirnica), nije neophodno blokirati funkcije OPEN (otvoren) I EARTHED (uzemljen).

Funkcija otvaranja Tokom rada pri otvorenoj poziciji, radna osovina sa pokretnim nožastim kontaktima menja poziciju "OPEN" na poziciju "CLOSED".

Sila mehanizma opruge obezbeđuje veliku brzinu zatvaranja i pouzdan priključak (povezivanje) glavnog el. kola.

Funkcija zatvaranja Tokom funkcije otvaranja, luk rotira pod uticajem sistema za sprečavanje el. luka, čime se na taj način sprečava razvoj fiksnog podnožja. Ovo vrlo efektivno uklanjanje el. luka obezbeđuje kratke periode iskrenja (varničenja). Rastavni razmak u gasu uspostavljen nakon otvaranja ispunjava uslove za rastavne razmake u skladu sa IEC 62 271-102 / VDE 0671-102 i IEC 62 271-1 / VDE 0671-1.

Funkcija uzemljenja Funkcija "UZEMLJENJE" je implementirana okretanjem radne poluge (rotiranjem, ako je to potrebno) sa pozicije "OTVOREN" na "UZEMLJEN".

Description

Režim rada (upravljanja)

opružnim mehanizmom /sa

akumuliranom energijom

Opružni mehanizam sa akumuliranom energijom se koristi za prekidače-rastavljače sa 3 pozicije u panelima transformatora (kao sklopka transformatora). Prvo, upravljačke opruge se pune funkcijom "spring charged". Zatim, otvaranje i zatvaranje se vrši preko zasebnih tastera. Akumulirana energija je dostupna za process otvaranja kada se VN HRC osigurač ili paralelni okidač (šent prekidač) (f-okidač) isključi. Nije potreban dodatni process punjenja za akumuliranu energiju. Ova akumulirana energija je već napunjena prebacivanjem sa pozicije "spring not charged"(opruga nije napunjena) na "spring charged" (opruga napunjena). Ova akumulirana energija sa predpunjenjem obezbeđuje da kombinacija prekidač-rastavljač/osigurač može isključivati sve vrste kvarova pouzdano čak i tokom zatvaranja. Nakon što je VN HRC osigurač isključen (okinut), crvena poprečna linija se pojavljuje na indikatoru "fuse tripped" (osigurač isključen).

Uglavnom je postrojenje opremljeno sistemom za izbacivanje radne poluge, što znači da, nakon punjenja opruga, radna poluga se izbacuje, na taj način se sprečava da slučajno ostane ubačena. Na zahtev klijenta, ovaj sistem za izbacivanje radne poluge se može izostaviti.


12

PAŽNJA!____________________________________________________________________________________Rizik od povrede! Kada punite oprugu, radna poluga se stavlja u otvor za pobuđivanje. Ako nema sistema za izbacivanje radne poluge, ona se okreće i na taj način može povrediti rukovaoca.

Ukloniti radnu polugu pre punjenja opruge.

Daljinsko el. isključenje prekidača-rastavljača sa 3 pozicije je moguće putem magnetnog kalema, npr. isključenje transformatora usled pregrevanja.

Kako bi se izbeglo termičko opterećenje paralelnog okidača u slučaju kontinualnog signala koji se može biti prisutan, isti se isključuje putem pomoćnog prekidača koji je mehanički spojen sa prekidačem-rastavljačem sa 3 pozicije.

U panelima transformatora, kontinuitet rada paralelnog okidača se može testirati samo kada se radna (upravljačka) poluga ukloni.

Description

Za indikator spremnosti za rad, kutija za merenje zaptivenosti gasa je instalitrana unutar posude postrojenja.

Spojni magnet, koji se nalazi na donjem kraju kutije za merenje, prenosi položaj kutije za merenje na armaturu smeštenu izvan posude postrojenja kroz ne-magnetnu posudu postrojenja. Ova armatura pomera indikator spremnosti za rad postrojenja.

Dok su promene u gustini gasa tokom gubitka gasa, koje su odlučujuće za dielektričnu snagu prikazane, promene u relativnom pritisku gasa koje su rezultat variranja temperature i eksternog pritiska nisu prikazane. Gas u kutiji za merenje ima istu temperaturu kao i u postrojenju.Uticaj temperature je kompenzovan istom promenom pritiska u obe zapremine gasa.

8.7 Gas leakage rate

Gas leakage rate The gas leakage rate is < 0.1% per year (referred to the absolute gas pressure).

8.8 Dielectric strength and site altitude

Dielectric strength • The dielectric strength is verified by testing the switchgear with rated values of short-duration power-frequency withstand voltage and lightning impulse withstand voltage according to IEC 62271-1 / VDE 0671-1.

• The rated values are referred to sea level and to normal atmospheric conditions

(101.3 hPa, 20 °C, 11 g/m3 humidity according to IEC 60071 and VDE 0111).

• The dielectric strength decreases with increasing altitude. For site altitudes above 1000 m (above sea level) the standards do not provide any guidelines for the insulation rating, but leave this to the scope of special agreements.

All parts housed inside the switchgear vessel which are subjected to high voltage

are SF6-insulated against the earthed enclosure.

Site altitude The gas insulation at a relative gas pressure of 50 kPa (= 500 hPa) permits switchgear installation at any desired altitude above sea level without the dielectric strength being adversely affected. This applies also to the cable connection, as only screened cable T-plugs are used.

Panels with HV HRC fuses are permissible up to a site altitude of 1000 m above sea level.

8.9 Selection of HV HRC fuse-links

Note to HV HRC fuse-links According to IEC 60282-1 (2009) Clause 6.6, the breaking capacity of HV HRC fuses is tested

within the scope of the type test at 87% of their rated voltage.

In three-phase systems with resonance-earthed or solidly earthed neutral, under double earth fault and other conditions, the full phase-to-phase voltage may be available at the HV HRC fuse during breaking. Depending on the size of the operating voltage of such a system, this applied voltage may then exceed 87% of the rated voltage.

It must therefore already be ensured during configuration of the switching devices and selection of the HV HRC fuse that only such fuse-iinks are used, which either satisfy the above operating conditions, or whose breaking capacity was tested at least with the maximum system voltage.

In case of doubt, a suitable HV HRC fuse must be selected together with the fuse manufacturer.

Allocation of HV HRC fuses and transformers

The three-position switch-disconnector in the transformer feeder (transformer switch) was combined with HV HRC fuse-links and tested in accordance with IEC 62271-105.

The following transformer protection table shows HV HRC fuse-links recommended for transformer protection. Furthermore, the switchgear also permits fuse protection of transformers up to ratings of 2500 kVA. Please contact us for such applications.

The protection table applies to:

• Maximum ambient air temperature in the switchgear room of 40°C according to IEC 62 271-1 considering the influence of the switchgear enclosure

• Requirements according to SEC 62271 -105

• As for design and construction of the foundation, the relevant standards DIN 43 661 "Fundamentschienen in Innenanlagen der Elektrotechnik" (Foundation rails in electrical indoor installations) and DIN 18 202 "MaBtoleranzen im Hochbau" (Blatt 3) (Measuring tolerances in structural engineering (Sheet 3)) apply.

• The dimensions of the floor opening and the fixing points of the switchgear frame are given in the switchgear documentation.

• Determine level differences between the installation surfaces of the panels using a measuring sheet, and compensate them with shims.

11.7 Comments on electromagnetic compatibility

To achieve appropriate electromagnetic compatibility (EMC), some basic requirements must be observed while erecting the switchgear. This applies especially to the installation and connection of external cables and wires.

Basic measures for ensuring EMC are already taken during design and assembly of the switchgear panels. Among other things, these measures include:• the low-voltage compartment is an integral part of the panel, which means that the

protection and control devices with the internal wiring are metal-enclosed;

• reliable earth connections of the frame parts via toothed contact washers or locking washers;

• inside the panel, wires are laid in metal ducts;

• spatial separation of sensitive signal wires from wires with high interference voltage levels;

• limitation of switching overvoltages of inductive loads (e.g. relay or contactor coils, motors) by means of protective circuits with diode, varistor or RC element;

• within the LV compartment, the secondary devices are mounted in defined zones;

• shortest possible connection between corresponding modules in subracks;

• consideration of the magnetic leakage fields of conductor bars and cables;

• protection of subracks and wiring backplanes against interference by perforated shielding plates;

• large surface bonding between all modules and devices as well as bonding to the earthing conductor of the switchgear assembly.

These measures basically enable proper operation of the switchgear itself. The planner or operator of the switchgear must decide whether additional measures are required depending on the electromagnetic environment where the switchgear is installed. Such measures must be implemented by the installation company in charge.

In an environment with heavy electromagnetic interference it may be necessary to use shielded cables and wires for the external connections in order to avoid interferences in the low-voltage compartment and thus, undesired influences on the electronic protection and control or other automation devices.

Cable shields must be electrically bonded to be able to carry high frequencies, and contacted concentrically at the cable ends.

The shields of cables and wires are connected and earthed in the low-voltage compartment.

Connect the shields to earth potential - with high electrical conductivity and all around as far as possible. Protect the contact surfaces from corrosion in case of humidity (regular condensation).

When laying cables into the switchgear assembly, separate the control, signaling and data cables and other lines with different signal and voltage levels by laying them on separate racks or riser cable routes.

Corresponding to the different shield designs, there is a number of methods to perform connection. The planning department or site management determines which of the methods will be used, taking EMC requirements into account. The preceding points should always be taken into account.

The shield is connected to cables or wires with clamps contacting all around, if low demands are placed on EMC, it is also possible to connect the shield directly to earth potential (combine or twist the shield wires) or via short cable connections. Use cable lugs or wire-end ferrules at the connecting points.

Always keep the connecting leads of the shields as short as possible (< 10 cm).

If shields are used as protective earth conductors at the same time, the connected plastic-insulated lead must be marked green/yellow over its entire length. Non-insulated connections are inadmissible.

17 Verification of safe isolation from supply

ADANGER!Mortal danger if safe isolation from supply is verified incorrectly!O Verify the perfect function of the voltage indicator and the coupling section in accordance with national standards

- on live equipment

- with a test unit according to IEC 61243-5/EN 61243-5

- on all poles^ Use only voltage indicators or devices to test the function of the coupling section according to EN 61 243-5 / IEC 61 243-5 / VDE 0682-415. (There have been no changes as against the old standard VDE 0681 Part 7 regarding the interface conditions, so that the corresponding indicators can still be usedn.)■=> Perform repeat test of interface conditions at the capacitive interfaces, as well as on the indicators according to the customer's specifications or national standards.Do not use short-circuiting jumpers as separate plugs. The function of the surge arrester installed is not guaranteed anymore if short-circuiting jumpers are used (see Page 22, "Voltage detecting systems").

Safe isolation from supply can be verified either with an HR or LRM voltage indicator or with a CAPDIS / VOIS / WEGA system.
