SF6 gas-insulated combined test transformer is specially designed for factory and field testing of metal-encapsulated power equipment (GIS), high-voltage power cables, and the production test of components required for GIS assembly (disc insulators, insulating structural parts, voltage transformers, etc.). Its advantage lies in its full encapsulation, which can complete partial discharge tests under normal conditions, and the discharge test background can generally be debugged at less than 1Pc. Installing high-voltage bushings on this equipment can also perform withstand voltage tests on conventional power equipment.
1. The device is small and can use the smallest space
2. The components are light
3. A strong and durable structure that can withstand long-distance transportation
4. Directly connected to the test product
5. All high-voltage parts are fully enclosed in a closed space to ensure the high safety of operators
6. A wide range of applications, with the addition of a casing, it can perform pressure tests on conventional equipment
7. Built-in high-voltage measurement and partial discharge coupling capacitors
8. The built-in high-voltage isolation switch can separate the interfaces of multiple test products to ensure safety during high-voltage testing
