Product features of the intelligent test bench for mining switch plug-in protection performance:
1. Both computer-operated and manual test methods are available, facilitating staff debugging and testing of plug-ins.
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. The first vertical cabinet is a three-phase test power supply (127V, 1140V) control cabinet.
5. The middle operation cabinet is a plug-in debugging cabinet.
6. The second vertical cabinet is a combined cabinet body for three-phase synchronous testing, vacuum characteristic tester, action characteristic testing, plug-in debugging box (KM-DS type), etc.
Detection functions of the intelligent test bench for mining switch plug-in protection performance:
1. Testing of all starter electronic protectors such as JDB, ABD, QJZ-300, PIR-400, etc.
2. Testing of protection plug-ins for all vacuum feeder switches 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.
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. Detection of three-phase closing synchronization of vacuum contactors and circuit breakers.
6. Measurement of vacuum degree (withstand voltage value) of vacuum contactor switch tubes.
