일반적으로, 가스 차단기(Gas Circuit Breaker) 혹은 가스절연개폐장치(GIS: Gas Insulated Switchgear)는 전기계통의 전원측과 부하측 간의 회로 사이에 설치되어 회로상에 지락이나 단락 등 이상전류가 발생하였을 때 전류를 안전하게 차단하여 전력계통 및 부하기기를 보호하는 전기기기로서 주로 초고압(High Voltage)용으로 사용된다. Generally, a gas circuit breaker or gas insulated switchgear (GIS) is installed between the circuit between the power side and the load side of the electric system to stop the current when an abnormal current such as a ground fault or short circuit occurs in the circuit. It is an electrical device that safely shuts off and protects the power system and load devices, and is mainly used for ultra-high voltage applications.

When injecting gas such as SF6 GAS into a gas insulated switchgear, a gas injection device is used.

Since it is an analog method, there is a problem that the pressure must be adjusted by guessing. Therefore, there is a need to improve this.

Specifically, when gas is injected into the gas insulated switchgear 20, the gas stored in the gas tank 10 flows through the first pipe portion 100, the passage hole portion 311 of the body portion 300, and the second pipe portion 400. It passes through and is injected into the gas insulated switchgear (20).
제2압력계(500)는 바디부(300)에 장착되고, 가스절연개폐장치(20)의 압력을 측정한다. 제2압력계(500)는 디지털압력계로, 가스절연개폐장치(20)의 압력을 측정하여, 가스절연개폐장치(20)의 현재 압력상태를 나타낸다. 즉, 가스절연개폐장치(20)로 주입되는 가스의 양을 측정할 수 있다. The second pressure gauge 500 is mounted on the body 300 and measures the pressure of the gas insulated switchgear 20. The second pressure gauge 500 is a digital pressure gauge that measures the pressure of the gas insulated switchgear 20 and indicates the current pressure state of the gas insulated switchgear 20.
