SF6 circuit breaker as a new type of high-voltage electrical switchgear developed in recent times, with its superior performance, safety and reliability, easy maintenance and long service life, has be...
Ⅰ. Temperature difference on the SF6 relay reading deviation impact problem1. The temperature value T body at the switch body and the temperature value T relay at the installation of density relay ar...
SF6 gas density meter shows the density of SF6 gas in the gas chamber of electrical equipment, which is expressed as the pressure of SF6 gas after temperature compensation, i.e. as the pressure value ...
The symbol of density is expressed by ρ, and the unit symbol is kg/m3 or g/L. According to the definition of density, the indication value of SF6 gas density metre should be the unit of density. Acco...
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...
