The KDGK-I High Voltage Switch Tester can be used for mechanical characteristic parameter testing and measurement of high voltage switches in power systems, including vacuum, sulfur hexafluoride, low-oil, and multi-oil types. The measurement data is stable, wiring is convenient, and operation is simple, making it a handy tool for the maintenance and testing of high voltage switches.

1. The instrument can automatically recognize the open and close states of the breakers and provide corresponding operation prompts based on the reference breaker status.

2. It features 6 independent breakers, capable of detecting and indicating the connection status of each breaker, facilitating user wiring checks.

3. The device can store up to 100 sets of test results internally.

4. It is equipped with a large screen LCD (320×240) display, featuring an advanced gray scale screen that does not reflect under sunlight and does not go black, providing clear graphic and Chinese menu operation prompts with a user-friendly interface for easy operation.

5. The instrument offers powerful graphical analysis capabilities, allowing waveform and measurement data to be displayed on the same screen, making the testing process more intuitive.

6. It includes a built-in delayed protection function that automatically cuts off coil voltage after circuit breaker operation, effectively protecting both the circuit breaker and the testing instrument.

7. This instrument supports both electric and manual open/close testing.

8. It can perform high and low voltage tests, automatically finding the open or close voltage.

9. For reclosing tests, it can measure parameters such as close-open, open-close, and open-close-open sequences.

1. Time Measurement: 12 channels

• Inherent opening (closing) time
• In-phase synchronization difference during opening (closing)
• Phase-to-phase synchronization difference during opening (closing)
• Bouncing time (number of bounces) during closing (opening)

2. Speed Measurement: Initial opening (closing) speed

Average speed over a specified time period (travel distance or angle segment)
