Product technical parameters and Structure dimension

Product structure features and working principle
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.

Environment condition
Ambient temperature:-10ºC-+40ºC
Relative humidity:The average humidity of a day should be no more than 95%. The average  humidity of a month should be no more than 90%.
Earthquake intensity:  not exceed 8 degrees.
Saturated vapor pressure the average pressure of a day should be no more than 2.2kPa; the average pressure of a month should be no more
Than1.8Kpa; The average pressure of a month should be no more than1.8 kpa;
The height above sea level:≤1000 m (Except special requirements)
It should be installed in the places without fire,  explosion, serious filth, and chemical erosion and violent vibration.
