Leak Testing High Voltage Switchgear - LACO Technologies

May 14, 2015 · Gas-insulated high voltage switchgear typically use a sulfur hexafluoride (insulating gas) gas to minimize arcing when the circuit breaker is activated. Leak testing of the subassemblies and finished product provide confidence that the sufficient pressurized gaz sf6 gas will be contained inside the unit to prolong its functional life. Leak testing also minimizes maintenance and reduces environmental emissions.Get price

Leak testing note #01-01 High Voltage switchgear

Several tracer gas leak test methods, at both the subassembly and final assembly level, can be employed for leak testing of high voltage switchgear. Consideration should be given to the methods’ ability to both locate the leak and certify the global leak tightness of the system. Both Sulfr hexafluoride and helium can be considered for tracer gas. Considerations in selecting the tracer gas include cost, convenience, test method flexibility, test method sensitivity, equipment cost.Get price

Diaphragm Vacuum Pump Guides and Reviews

Diaphragm Vacuum Pump OperationPerformanceCharacteristicsApplicationsBrands and PricesDiaphragm vacuum pump consists of the following main parts as the follows: 1. The diaphragm which is made up of thermoplastic, rubber, Teflon or any elastomers. 2. Check valves – installed at both the inlet & outlet ends. 3. Cylinder – the container through which the air, gas or vapor is transferred to the different chambers. 4. Power Supply - External power source is required to move the diaphragm in the cylinder. Initially, the diaphragm is pulled out in the cylinder and increases the area in the cylinder. Thus a partial vacuum is created in the cylinder. Due to the pressure difference, the air, gas or vapor molecules move into the cylinder through the check valve. The check valves allow the flow through one direction and block the backflow of the air. Now the diaphragm is pushed to compress the air. The compressed air flows through the discharge of the pump to the required chamber. The check valve is placed at the discharge side of the pump to stop the backflow. Thus the air or g...Get price
