FZ (R)?n25-12 series indoor AC high voltage vacuum load switch (fuse combination)
產品詳情

   

Fzn25-12d / 630-20 AC high voltage vacuum load switch is an indoor device with three-phase AC 50Hz and rated power of 12kV. It is suitable for industrial and mining, enterprises, distribution substation and substation. As the protection and control of electrical facilities, it is used for switching load current, closed-loop current, no-load transformer and cable charging current. Equipped with manual and motor operating mechanism, it is convenient to realize the three remote control requirements of power system. Fzrn25-12d / t200-31.5 AC high voltage vacuum load switch fuse combination is an indoor device with three-phase AC 50Hz and rated voltage of 12kV. It is suitable for industrial and mining, enterprises, distribution substations and substations for load control and short-circuit protection. The equipped grounding switch can withstand short-circuit current. The operating mechanism can be operated manually and electrically, which is convenient to realize the three remote control requirements of the power system.

Fzn25-12d and fzrn25-12d load switches and combinations are applicable to urban distribution stations and industrial electrical equipment with three-phase ring network or terminal power supply for load control and short-circuit protection. Because the protective effect of the combined apparatus on electrical equipment such as transformer is more reliable and economical than the circuit breaker, it is especially suitable for ring network, double radiation power supply unit and box substation.
