Ⅰ. Specific analysis of the impact of sunlight radiation on SF6 relaysDue to the strong sunlight radiation makes the density relay metal shell temperature is much higher than the ambient temperature,...
1. The basis of using SF6 relayFrom the existing experience and theoretical analysis, such structure SF6 relay is adopted on the basis of the following.(1) Although the pure SF6 gas pressure-temperatu...
The density relay is one of the main components for monitoring SF6 electrical equipment. It monitors the pressure value of SF6 gas in real time, thus ensuring the insulation strength inside the electr...
In the power system, SF6 relay is a widely used protection and control element, its role is to monitor the SF6 gas pressure in the confined environment of high-voltage switches, GIS, etc., so as to en...
GIS is gas insulated fully enclosed combined electrical apparatus is a high, fine and sharp transmission and substation equipment developed in recent decades, and the maintenance workload is small, hi...
Ⅰ. What is the necessity of installing SF6 relay?With the development of electric power industry and the progress of science and technology, the online operation equipment of electric power system is...
SF6 gas has good insulation and arc extinguishing properties, so it is more and more widely used in various high-voltage equipment, such as high-voltage switches, transformers, reactors, transformers ...
