高壓熔絲鏈開關

高壓熔絲鏈開關

Introduction:

 

Primary function of high-voltage fuse-chain is used to exclude electrical equipent overload or short circuit with power system.It can cut off live circuit with power system.The technical and testing are accordance with NEMA SG2-1976 standard.

 

Main technical data:

 
1 Rated Voltage kVrms 7.2/14.4
2 Rated line to ground / line Vottage kVrms 7.2/12.47
3 Rated maximum Vottage kVrms 15
4 最Maximum line to ground / line Vottage kVrms 7.8/13.5
5 Rated impluse Vottage kVrms 95
6 Rated continuous Current kVrms 100
7 Rated breaking current kVrms 10 kA at 7.8 kV
8 Rated frequency kVrms 60

The characteristic of equipment:

 
  1. No any contact pole with current pathway.
  2. Contact pole with current pathway is used silver copper to good electrial conductor.
  3. It can be used to changeable screw-cap or extendable fuse-chain device.
  4. It can easily use rod to push or pull fuse tube.
