Compact IntegratedDistribution Substation(CIDS)

2

• SAVE SPACE2.5m2 footprint for CIDS up to 630kVA.

• SAVE THE ENVIRONMENTNo SF6, No PCB.

• SAVE MONEYSave up to 50% from conventional package substation with housing.

• ENSURE SAFETY FOR PUBLICNo exposed live parts.

• ENSURE SAFETY FROM FIREIf filled with flame retardant fluid.

2- DESCRIPTION

The CIDS is a compact fully integrated outdoor package substation with mediumvoltage equipment, transformer, and low voltage equipment. The packagesubstation is completely manufactured and assembled ready for installation on site.It ensures a high level of protection against access to live parts with a protectiondegree of IP 54 according to IEC 60529.

The operation and control is achieved from the front of the unit, with separatecompartments for medium voltage and low voltage sections. Four lifting lugslocated on the upper part enable the lifting of the complete unit easily.

2.1. Major Benefits

2.1.1. Compact design-Reduced footprint• Reduction of space requirement.• Reduction of footprint.

2.1.2. Cost Savings• Minimum installation and maintenance labor costs.• Minimum civil work; no building or vault structure.• No need for main low voltage circuit breaker.

2.1.3. Operational Integrity• Components are assembled and tested as an integral unit at the factory.• Access to all elements of control and protection in one casing.

2.1.4. Safety• Live parts inside the secure enclosure are hidden from the public andenvironment.• If filled with flame retardant fluid, risk of transformer fire is greatly reduced due to

high fire and flash points.

2.1.5. Environmental Integrity• Low profile design requires minimum real estate.• Dielectric fluid replaces ozone-depleting SF6 gas, currently used in RMU switching

modules.

2.2. Main Components

2.2.1. Enclosure

Single compact enclosure housing the transformer, medium voltage and low voltagesections.The is designed to be installed outdoor, with a protection degree of IP 54 accordingto IEC 60529

2.2.2. Low voltage sectionThis section can be designed and manufactured according to the needs of eachcustomer. Basic equipment includes:Low voltage bushings• Three current transformers• Four outgoing circuits by fuse links• Three ammeters• One voltmeter + one selector switchOptional: • Circuit breakers instead of fuse links• Multifunction electronic meter

2.2.3. Medium voltage sectionIt includes the following components:• Plug-in bushings• Two sectionalizing switches for incoming and outgoing lines with earthling facility• Main interrupter for protection against overloads and secondary short circuits• Backup fuses for protection against internal faults• Tap changer for voltage control (off-load)• Voltage presence indicators• Hotstick for sectionalizing switch operationOptional:• Earth fault and short circuit indicators

2.2.4. Transformer sectionIt includes the core and the windings of the transformer.
