10KV消弧消谐电阻器

In distribution systems technique of neutral ground is usually categorized into neutral unground, neutral ground via resistor, and neutral-point grounding via arc suppression coil. Differnent grounding ways decide various operating ways. With development of economy , over-head line which is the main way of past power grid has been replaced by cable running line. Meanwhile, some new equipments such as hermetic compact structure of SF6 swichgear, twisted polyethylene cable and zinc oxide arrester are more and more widely applied. Therefore, non-effective grounding technique is unsuitable to present situation. As a result, to set
