1 product features:

1, product structure features overview

1.1 a switch cabinet body using aluminized zinc plate, the CNC machining and take multi folding technology, make the whole cabinet body not only has the advantages of high precision, strong corrosion resistance and antioxidation and due to the adoption of the multi folding technology, the cabinet has light overall weight, compared with other similar equipment cabinets, high mechanical strength, beautiful appearance. Cabinet with assembled structure, covers an area of small, easy to organize production.

1.2 small size cabinet, saving the occupied area and space.

1.3 main switch for miniaturized vacuum circuit breaker and modular design structure makes the replacement body parts is simple and convenient. Arc extinguishing device adopts horizontal installation and vacuum arc extinguishing chamber adopts domestic advanced manufacturers of products, ensure product excellent breaking, closing and dynamic thermal stability. And the circuit breaker with a fixed installation, greatly improving the circuit breaker dynamic thermal stability and makes operation more simple, circuit breaker voltage, parameter measurement, and other more convenient.

1.4 isolating switch for the design of miniaturized isolating switch and the isolating switch is the rotation of the screw driven dynamic contact horizontal trolley forward and back off of, contact connection mode is static end by selecting a small volume, high reliability of the watch chain structure. Grounding switch is dividing and combining with worm drive. Operation, labor saving, reliable, miniaturization design effectively reduced the size of the switch cabinet.

1.5 has a reliable "five anti" function. The front door has forced mechanical locking, the operation mode is rotary type, convenient, flexible, and labor saving.

2, the circuit breaker room is located in the middle of the front part of the cabinet body is, using a circuit breaker has the advantages of novel structure, excellent performance of vacuum circuit breaker. Circuit breaker chamber is provided with a pressure releasing chamber, to release internal fault electric arc generated by the pressure to ensure switch cabinet and the safety of the operator; cabinet door is provided with an inspection window, observable isolation switch position.

3, bus room is located in the middle to upper part of the cabinet body, main bus through the branch bus bar and the isolating switch is connected, in the bus through the switch cabinet by wall bushing is fixed, the accident, limiting the spread to the adjoining cabinets, and to ensure that the mechanical strength of the bus.

4, relay instrument indoor installation of relay protection and measurement instruments, switching switch, live display device, signal lights and other control, protection, signal equipment.
