Product Features:
1. Both computer-operated and manual test methods coexist, facilitating debugging and inspection of plug-in units by staff.
2. The test circuit fully simulates the working state of underground switchgear.
3. Each item must be tested sequentially as specified; 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 plug-in debugging cabinet.
6. Cabinet 2 is a combined cabinet housing three-phase synchronous testing, vacuum characteristic tester, action characteristic testing, plug-in debugging box (KM-DS type), etc.
II. Testing 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 plug-ins such as BKD9, BKD1, BKD16, BKD20, KBZ1, DT5, etc.
3. Testing function for relay protectors used in BGP series vacuum distribution devices, with specific manufacturer and model provided by the user.
4. Testing of electronic protection plug-ins used in ZBZ, ZBX series electric drills and lighting signal protection devices, applicable to all manufacturers and models.
5. Synchronism detection of three-phase closing for vacuum contactors and circuit breakers.
6. Measurement of vacuum degree (withstand voltage) of vacuum contactor switch tubes.
