The neutral point grounding system of three-phase transformers in 330KV, 220KV, and 110KV voltage levels is generally called a large current grounding system; the neutral point of three-phase transformers in 35KV, 10KV, and 6KV voltage levels can be grounded through arc suppression coils, electric positive grounding, or ungrounded systems, which are generally called small current grounding systems.
BH-ZD) series transformer neutral point grounding protection device is a protection device specially produced by Baoding Baihong Electric Technology Co., Ltd. for 220KV, 110KV, transformer coil neutral point grounding. In the power system fault, the asymmetric three-phase fault can be decomposed into positive sequence component, negative sequence component and zero sequence component, and the neutral point grounding channel of the transformer coil is the zero sequence current path channel. The zero sequence protection device selectively cuts off the fault component according to the zero sequence voltage and zero sequence current. The single-phase original switch in the BH-ZD series transformer neutral point gap protection device, composed of components such as current mutual inductance and discharge inductance, is designed to realize two different operation modes of neutral point grounding or ungrounding, thereby avoiding the transformer neutral point from being damaged by voltage rise caused by the voltage and current path, and causing damage to the transformer insulation. This product can be widely used in power, metallurgy, chemical industry and coal industry.
