The GE-ZCB type transformer neutral point gap protection device is a complete set of equipment that combines electrical equipment such as isolation switches, zinc oxide lightning arresters, discharge gaps, and current transformers. It has the characteristics of full functionality, small size, high reliability, and easy installation and commissioning. Lightning arresters and isolating switches can be combined and selected according to engineering needs. The operating mechanism of the isolation switch can be selected to use manual or electric mechanism according to engineering requirements.

The GE-ZJB type neutral point gap protection device can achieve two different operating modes of transformer neutral point grounding operation or ungrounded operation. In order to avoid damage to the transformer caused by the increase of neutral point voltage due to system failure. This product is widely used in fields such as power, metallurgy, petrochemicals, mining, and building environmental protection.
Features:
1. The GE-ZJB type neutral point gap protection device is equipped with electrical equipment such as discharge gaps and current transformers, and has the characteristics of small size, easy installation and debugging, and high reliability.
2. The GE-ZJB type neutral point gap protection device adopts a spherical discharge gap method, which has higher accuracy, less dispersion, and stable characteristics than the commonly used rod discharge gap discharge voltage. It has precise and effective connection with the lightning arrester characteristics and the main transformer, large heat capacity, and is not suitable for burning, improving the safety and effectiveness of protection.
3. The GE-ZJB type neutral point grounding gap complete set device can adopt spherical gap or rod-shaped gap. The technical parameters of the gap can be debugged in the factory or on-site.
