DESIGN

The power transmission box features a sealed enclosure of powder-coated aluminium. The trolleybus high-current line components within the ENI-ZNT200/UKR/072016 system are laid out inside the power transmission box, the interior of which can be separated into three functional compartments. .The power transmission box typically features these three function blocks, or modules: LV and HV switchboards, transistor inverter, and static converter. The transistor inverter and the static converter feature forced external air cooling. The ENI-ZNT200/UKR/072016 power transmission box is a roof-mounted unit. .

INVERTER

DESIGN AND APPLICATIONThe onboard inverter provides a controlled-frequency AC voltage supply for the asynchronous traction motor. The inverter features a dedicated microprocessor controller supervised by the SNT trolleybus controller, and both communicate with each other via the CAN bus. Current monitoring of both the power transmission system status and vehicle starting parameters is provided through a CAN-connected control panel. The power transmission system enables low-voltage driving at 60 V to 110 VDC (e.g. for passing a drive-through wash). The inverter also enables current filter switching (with the current levels preset in the firmware). The power transmission system prevents the trolleybus starting current from energizing any unwanted resistors and enables braking energy recovery to the contact system at its maximum permissible levels. If the contact system cannot receive the whole energy recovered from braking due to a risk of overvoltage, the trolleybus power transmission system dissipates the surplus energy in a resistor, thus maintaining the maximum permitted voltage over the contact system. A contact system voltage loss, or a dip below the minimum permitted limit, blocks the braking energy recovery to the contact system. The trolleybus controller activates a full resistor braking mode. If the braking energy recovery has not been turned on or it has been interrupted, the controller starts or resumes the process whenever the prerequisites for doing so are met. The power transmission system does not emit any high, onerous noise or squeal under normal operating conditions. The average power consumption of the trolleybus in normal urban traffic conditions with the onboard heating system off is 1.4 kWh/km max. .

The traction inverter comprises:a fully controlled power electronic IGBT reverser,a three-phase IGBT bridge,an electromagnetic braking system based on an IGBT module,a power filter, formed by a bank of C-capacitors and an L-choke,a control system, comprising: an onboard controller power supply unit and a PWM modulator, which outputs transistor switch control signals, .sensor array for monitoring the traction inverter.

STATIC CONVERTER

APPLICATIONThe static converter provides full galvanic separation and two-stage insulation of the control lines and outputs from the 550 V DC

contact system power that is externally measurable. All static converter power outputs for external devices are protected against shorting and overload. The static converter is powered downstream of the system bias controllable reverser for the power transmission converter, so as to be able to run on recovered braking energy when powered from the contact system. The static converter provides 24 V to the auxiliary and control lines, 3 × 400 V, 50 Hz voltage to the piston compressor and the power steering DC

pump, and separated 24 V voltage. The static converter also backups the power steering pump for 10 seconds after loss of contact system voltage. .
