HV Switchgear
Summary
KYN61-40.5 refers to armored removable AC metal-enclosed switchgear, which is a three-phase AC 50Hz, rated voltage 40.5kV indoor complete power distribution device. It is used for receiving and distributing electric energy in power plants, substations, and industrial and mining enterprises, and has functions such as control, protection, and detection of circuits. It can also be used in places with frequent operations.。
Dimension
1400(1680)mmx2800mmx2600mm
Structural Characteristics
- Metal armor, assembled structure, multiple combination schemes
- The cabinet is made of aluminum-zinc plate, processed by CNC equipment and laser cutting equipment, using advanced multiple folding technology, connected with rivet nuts and high-strength bolts, with high precision, corrosion resistance, light weight, high strength, and strong parts versatility
- It can be equipped with a variety of vacuum circuit breakers and SF6 circuit breakers, with wide practicality, high reliability, and year-round maintenance-free
- The trolley has three positions: working, testing, and disconnecting. Each position has a positioning and display device that is safe and reliable
- All types of trolleys are configured in a modular manner to ensure that trolleys of the same specification can be freely interchanged
- Highly reliable interlocking device fully meets the "five protection" requirements
- Each high-voltage room has an independent pressure relief channel to ensure personal safety
- Complies with GB3906, IEC298 and other standards
