Transformer protection cubicle with circuit breaker and voltage transformer

A required mechanism for connection the electricity which is generated at a company's power plant to a distribution site or substation is called auto-producing feeder.

Content

Busbar: copper units that connect the equipment to each other.

Load Break Switch(switch disconnector); Medium-voltage switchgear devices that are capable of opening and closing under load . Active parts of them has been made from epoxy resin and MV switchgear devices  located into the hopper within the SF6 gas filled with a sealed pressure system.   There is 3 position; open, close and earthing. Earthing switch in the SF6 gas has the ability of closing on by-pass.

Earthing switch: Provides connection between electrical circuits that are not under tension and earth. It is air-insulated.

Circuit Breaker : A circuit element capable of opening and closing under all kinds of loads including by-pass. Its mission; to cut off load flow when it closes. It protects the circuit against by-pass etc. It has 3 poles. All active components are within the enclosure filled with SF6 gas. There are varieties of front-and side-mechanism.

Current Transformer: It reduces to the desired value for the purpose of protection or measuring the current of the busbar. It is used as epoxy resin or set of LPCT. Its ends are not left open.

Voltage transformer: It reduces to the desired value for the purpose of protection or measuring the voltage of the busbar. It is epoxy resinous.

Relay: It is used for the purpose of operating the related mechanisms, measuring instruments  and human-machine interfaces according to vectorial values converting the energy in the busbar to the analog or digital signal.

Voltage Indicators: lighting panel of the capacitive voltage indicator showed that there is any energy on the cable connection point in cubicle is on side of front of the cubicle .

Heater : It prevents to occur moisture drying the air.
