KYN28-12 Temporary power 10 pair socket distribution box is a complete set of power distribution devices of 3.6kV ~ 12kV 3 phase AC 50Hz single bus or single bus sectional system.
The switchgear comes out with a variety of protection functions,including preventing pulling or pushing circuit breaker handcart in load mode,preventing turning on/off the circuit breaker by mistake, preventing turning on the circuit breaker when the grounding switch is in ON position, preventing entering the energized cubicle by mistake, and preventing turning on the interlock function of the grounding switch by mistake in energized state.
The switchgear is mainly used in power plants, small and mediumsized power generators, industrial and mining enterprises, and secondary substations of power system for power receiving, power transmission, and startup of large-sized high-voltage motor in order to implement control, protection, and monitor.
Structural Features
◆All the devices can be operated under the door closed.
◆High sealing degree of the cabinet, prevent trashes and pest invasion.
◆Encolure Protection level of IP4X.
◆Simple and effective lock systemt prevent misuse. Perfect "Five Protection" interlock device.
◆Replace circuit breaker easily.
◆Indoor HV vacuum circuit breaker and its operating mechanism requires little maintenance.
◆The secondary wire is fixed to the inner wire casing of ample size, easy for wiring connection.
◆Cable compartment installation process could be easily observed by observation window panel.
