Technical Features
1. Both computer-operated and manual test methods coexist, facilitating debugging and testing of plugins for staff.
2. The test circuit fully simulates the working state of underground switches.
3. Tests must be conducted item by item as required; otherwise, test reports cannot be automatically generated, ensuring scientific management.
4. Cabinet 1 is a three-phase test power supply (127V, 1140V) control cabinet.
5. The middle operation cabinet is a plugin debugging cabinet.
6. Cabinet 2 is a combined cabinet including three-phase synchronous testing, vacuum characteristic tester, action characteristic testing, plugin debugging box (KM-DS type), etc.
Detection Functions
1. Testing of all starter electronic protectors such as JDB, ABD, QJZ-300, PIR-400, etc.
2. Testing of all vacuum feeder switch protection plugins such as BKD9, BKD1, BKD16, BKD20, KBZ1, DT5, etc.
3. Testing function for relay protectors used in BGP series vacuum power distribution devices, with specific manufacturer and model provided by the user.
