KRU-RH-UHL5-VB is a complete switchgear with a vacuum circuit breaker, power supply and control units of the circuit breaker, non-linear overvoltage limiters (OPN), microcontroller protection of feeders MKZP, current sensors.
Switchgear-RH is designed for distribution of electrical power voltage 6/10kV frequency of 50 Hz in networks with insulated neutral in various industries in underground mine workings and mines, not dangerous in terms of explosion of gas, steam or dust.
Convenience in operation, autonomy
The switchgear-RH has its own auxiliary transformers NOL, which provide power to the operating circuits of the cabinet. Thus, a separate cabinet with its own auxiliary transformers is not required to supply the substation.
Besides, the NOL transformer has a winding, which allows measuring the network voltage with accuracy sufficient for realisation of relay protections, therefore installation of additional cabinets of voltage transformers as a part of RP is not required.....
