Helium leak detection equipment for Gas Insulated Switchgear
The helium leak detection equipment for gas insulated switchgear (switchgear filled with gas) is a specialized high-precision instrument designed to detect helium leaks within gas insulated switchgear. gas insulated switchgear, commonly used in power systems, operates under the protection of insulating gases such as helium, making the detection of seal integrity crucial. The helium leak detection equipment takes advantage of helium’s unique properties, such as its small molecular weight, strong permeability, and extremely low concentration in common gases, to achieve sensitive detection of minor leaks.
The equipment typically includes a helium detector, a vacuum pump, and a control and analysis system. During the detection process, the gas insulated switchgear is first evacuated using the vacuum pump, and then helium gas is introduced either externally or internally to the gas insulated switchgear. The helium detector then scans potential leak points such as the sealing interfaces and welds of the gas insulated switchgear, determining the presence of leaks by detecting changes in helium concentration.
The helium leak detection equipment for gas insulated switchgear is highly sensitive and accurate, capable of identifying and locating minor leaks in a very short time, ensuring the safety and reliability of the gas insulated switchgear. Additionally, the equipment usually comes with a user-friendly interface, making operation straightforward and efficient for data analysis and report generation. By utilizing this advanced detection equipment, power equipment manufacturers and maintenance teams can enhance product quality and ensure the safe and stable operation of the power grid.
