Product Description

Intelligent Test Bench for Protection Performance of Mining Switch Plug-ins

Relay protection plug-ins, vacuum feeder protection plug-ins, vacuum electromagnetic starter protectors, electric drill comprehensive protection plug-ins, and lighting signal comprehensive protection plug-ins for high-voltage distribution devices of various models and manufacturers.

The intelligent test bench for protection performance of mining switch plug-ins can be designed and added with test interfaces for other protection plug-ins according to user requirements, completing tests of overload, short circuit, phase loss, leakage, and other protection performance parameters for all plug-ins. It can also meet the three-phase synchronous testing of electromagnetic starters and feeder switches, vacuum degree testing of switch tubes, and contactor action characteristic testing. Data is automatically collected by computer, and test reports are printed.

Explosion-proof electrical appliance test bench, intelligent switch plug-in test bench, intelligent test bench for protection performance of switch plug-ins, intelligent test bench for protection performance of mining switch plug-ins

Product Features:

I. Technical Features and Configuration Description

1. Both computer operation and manual operation test methods coexist, 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 the three-phase test power supply (127V, 1140V) control cabinet.

5. The middle operation cabinet is the plug-in debugging cabinet.

6. Cabinet 2 is a combined cabinet 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 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 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.
