Helium leak detection equipment for ring main units is a specialized high-precision device used to detect gas leaks in RMU within the power system. Here is an introduction to some of the main parameters of the equipment:

1. Leak Detection Precision: The leak detection instrument has a very high precision, capable of accurately identifying even minor gas leaks. This is crucial for ensuring the safe operation of the power system, as even minor leaks can lead to reduced system performance or failure.
2. Working Cycle: The working cycle refers to the time it takes for the equipment to complete a leak detection operation. For example, the detection time for large充气柜 does not exceed 45 minutes per item, and for small ones, it is less than 25 minutes. Such efficiency can meet the demands of continuous production and improve production efficiency.
3. Helium Recovery Rate: The helium recovery rate is an important indicator of how much helium the equipment can recover during the leak detection process. A high recovery rate (such as 95-98%) means efficient use of resources and cost savings. This is beneficial for both the environment and economic performance.
4. Pressure Difference Control: The equipment can maintain a certain range of pressure difference between the inside and outside during leak detection and gas charging, preventing deformation of the workpiece. This is typically achieved by setting a maximum pressure difference value (such as 0.03MPa).
5. Safety: The equipment is equipped with high-pressure gas charging protection, safety light grid protection, emergency stop switch, and other safety interlock protection measures. These functions ensure the safety of operators and equipment, preventing accidental incidents.
6. Automation Level: Modern helium leak detection equipment for ring main units usually has a high level of automation, such as PLC control, which can automatically complete processes like evacuation, helium charging, leak detection, and venting without manual intervention. This greatly improves the simplicity and reliability of operations.
7. Fault Diagnosis and Data Traceability: The equipment may have functions such as online micro-water measurement, vacuum drying for dehumidifying, and fault record functions. Each operator has their own operation account password, and original data can be traced and queried. These functions help quickly troubleshoot faults, ensure continuity of production, and provide a basis for quality control.
