Portable Live Detection Devices for On-load Tap Changers
Clicks:
-
Live detection: detection of the internal mechanical structure and electrical state of the tap changer without power cutoff and disassembly of the tap changer body.
- Simple operation: In only requires to install the accelerometer on the side wall of the transformer and fix the current clamp on the motor drive power cable of the operating mechanism to perform the test.
- Special analysis software: With internationally leading analysis technologies, the operating status of the tap changer is determined based on the analysis of the vibration signal and the motor current signal.
- Wide range of faults, including operating mechanism failure, insufficient energy storage of the spring, contact jamming, contact wear, insufficient lubrication, insufficient switching, abnormal switching sequence, and abnormal braking.
- A friendly human-machine interaction system: The instrument is equipped with a laptop; after the test is completed, the laptop can display, record and store characteristic parameters.
- Lightweight and easy to carry.
