Shaanxi Lanhe Electric Engineering Co., Ltd. LH500 Transformer New Neutral Point Assembly
The LH500 transformer new neutral point assembly is used for the 110kV coil neutral point of power transformers. It is composed of single-phase isolating switches, neutral point lightning arresters, disconnectors, current transformers and discharge gaps. It is used to realize the transformer 110kV coil neutral point grounding or It has two different operating modes of non-grounding, and clamps the neutral point power frequency overvoltage, while preventing the misoperation of the relay protection caused by the discharge of the rod gap under lightning and operation overvoltage.
