Description

FKRN12-12KV 125A 630A high pressure indoor compressed air load switch

overview: indoor compressed air load switch

Indoor compressed air load switch, FK (R) N12-12D/T type high voltage load switch is suitable for 12KV and below three-phase high voltage switching equipment, as transformers, cables, overhead lines and other power equipment control box protection; It is especially suitable for terminal substation and box-type substation of urban network and agricultural network. And suitable for ring network, double radiation power supply unit control and protection.

Product Structural Features :

Load switch for the frame structure, unique structure compact, integrated isolating switch, load switch, fuse, grounding switch is one of the high voltage electrical products .

Isolating switch for direct drive type, motion direction and motion parallel to the direction of the vacuum interrupter. Separate switch has obvious partition port security barrier, when the grounding switch on at the same time, and the safety barrier grounding switch static contact linkage automatically charged (closed busbar chamber), repair or replace the fuse is absolutely safe.

Isolating switch, load switch on-off sequence mechanical procedure guarantee. Closing operation, isolating switch, load switch it on first after closing. The opening operation, load switch off after the first isolating switch gate.
A mechanical interlock to prevent mis-operation between load switch and earthing switch.

The load switch with lock, can easily switch cabinet and the switch when the door open or the door interlock, door unlocked, load switch can not operate, when the grounding switch does not switch on, the door cannot be opened.
Load switch for electric manual can realize remote control
