1. Overview of vacuum pressure gaugeThe vacuum pressure gauge is an instrument used for vacuum pressure measurement. It uses atmospheric pressure as a reference and is an instrument used to measure le...
1. What is SF6 gas density?The value of SF6 gas density is expressed by the pressure after temperature compensation of SF6 gas, that is to be expressed as a standard pressure value when it is 20°C.2....
1. The function of vacuum pressure gaugeThe vacuum pressure gauge is suitable for measuring the pressure of liquid, steam, gas and other media that are non-explosive, non-crystallized, non-solidified,...
SF6 gas has become an insulating and arc extinguishing medium with its excellent electrical and physical and chemical properties, and is widely used in the field of power transmission and transformati...
1. SF6 relay should have the following functions1) Monitor the SF6 gas pressure inside the circuit breaker;2) Distinguish whether the cause of the decrease in gas pressure is the decrease in ambient t...
1. Calibration principle of SF6 relayIn a closed container, the SF6 gas pressure at a certain temperature can represent the density of SF6 gas. And the SF6 gas pressure at 20°C is often used as the d...
1. The composition of SF6 relaySF6 relay is an important protection and control component in the power system. The failure of the circuit breaker will cause great economic losses. To ensure the reliab...
