GW13 40.5kv 72.5kv 126kv Lightning Protection Equipment Disconnect Switch

Overview of Disconnect Switch 

Disconnect Switch . GW5 type isolation switch is a switch in the no load flow conditions for high voltage transmission line,and the  high voltage bus, is maintenance of  the  circuit breaker  and  other  electrical  equipment  and  charged  high  electrical isolation in,in the main switch in the normal brake position-provide a meet safety requirements can  see  insulation distance.

Meet the GB1985″IEC-129″AC isolation switch and the isolating  switch(1984)” and the earthing switch”  standard  AC  isolation switch.Therefore, it  is  reliable, safe  operation;  and  has  the  advantages  of  small  volume, simple structure, convenient in stallation and  debugging.

Consisting  of  three  monopoles  and  mechanism, each  single pole, isolating switch consists of two post insulator are respectively fixed on a base,an angle of  50 degrees  into a V type structure,one side of the body to rotate through a porcelain vases.bevel gear switch in the base.

The main circuit adopts copper material,local two silver plated contact,contact,through flow capacity,operating mechanism adopts CS17 manual mechanism,light and flexible,there is a mechanical interlocking  mechanism  design between the output shaft, and can be equipped with electromagnetic lock, can ensure that  the  anti  misoperation, also  can be equipped with CJ11type electric operating mechanism.

In order to facilitate the  different  user  requirements. Is a high-voltage electrical products cheap,widely used in power plants and power plants.

Applictaion

The “GW9-10G” type of outdoor high voltage isolate switch is the high voltage switch equipment of single phase AC 50Hz. The product is suitable for power system with rated voltage 10kV to make or break power supply under circumstances of with voltage and nonload.

The isolator is adopts isolated hook rod to operated.
Normal service conditions
1.The altitude does not exced 1000m;
2.The ambient air temperature:Maximum +40℃;Minimum:General Area -30℃,Paramos -40℃;
3.The wind pressure does not exceed 700Pa.(corresponding to 34m/s wind speed);
4.The earthquake intensity does not exceed 8 degrees;
5.The working situation is without frequent violent vibration;
6.The installation site of ordinary type isolator should be kept away form gas, smoke chemical deposition, salt-spray fog, dust
and other explosive and corrosive maters that affect seriously insulation and conduction capability of the isolator.
7.Pollution-proof type isolator is applies to severe filthy conduction area, however , it shouldn’t be any explosive matters and matters causing fire.
