Cable Withstand Voltage Test Device
Darui Electric recommends for you
I. Product Application:
1. AC withstand voltage test for 6kV-500kV high-voltage cross-linked cables
2. AC withstand voltage test for generators
3. AC withstand voltage test for GIS and SF6 switches
4. Power frequency withstand voltage test for 6kV-500kV transformers
5. AC withstand voltage test for other high-voltage power equipment such as busbars, bushings, and instrument transformers.
II. Main Functions:
(1) Remote measurement function of reactor core gap:
This device is equipped with a gap sensor on the reactor, and the core gap can be directly read on the control console to guide operation. In addition, a gap limit switch and indicator are installed.
(2) Automatic voltage reduction function after withstand time:
The withstand voltage timing uses a digital timer. When the withstand time is reached, the system will automatically reduce the voltage.
Zero-position closing and zero-start voltage boosting function:
It has a zero-position limit function. If the voltage regulator is not at zero position, the high-voltage output button cannot be closed, ensuring the system starts boosting from zero.
Overcurrent protection function:
The system is equipped with an electromagnetic overcurrent relay, which has strong anti-interference ability and fast action, avoiding damage to the test object from overcurrent.
Mainly used for the following aspects:
1. AC withstand voltage test for 6kV-500kV high-voltage cross-linked cables
2. AC withstand voltage test for generators
3. AC withstand voltage test for GIS and SF6 switches
4. Power frequency withstand voltage test for 6kV-500kV transformers
5. AC withstand voltage test for other high-voltage power equipment such as busbars, bushings, and instrument transformers.
