Product Introduction
The neutral point grounding protection device is a set of products developed and operated by our company based on years of experience in overvoltage protection product development and operation. According to the requirements of the "18 Major Anti accident Measures for Power Grids of State Grid Corporation of China" to prevent grounding grids and overvoltage accidents, we have developed a complete set of products for transformer neutral point grounding in China. This product can achieve two different operation modes of transformer neutral point grounding or ungrounded, thereby avoiding damage to the transformer caused by the increase of neutral point voltage due to system faults.
In order to monitor the operation of the system and improve the intelligence of the power grid, our company has specially developed the JJ-III intelligent monitor, which can monitor the surface pollution current of the isolation switch insulator in real time, monitor the leakage current and action frequency of the lightning arrester in real time, and monitor the action frequency of the discharge gap in real time. It has an RS485 communication interface to transmit monitoring information to the upper computer, making it convenient for inspectors to query, analyze, and judge.
