I. Technical Features and Configuration Description
1. Both computer operation and manual operation 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. 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 body for three-phase synchronous testing, vacuum characteristic tester, action characteristic testing, plug-in debugging box (KM-DS type), etc.
II. 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 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. Three-phase closing synchronization detection of vacuum contactors and circuit breakers.
6. Measurement of vacuum degree (withstand voltage value) of vacuum contactor switch tubes.
