Detailed Product Description: | The Hainan lightning arrester Hainan, Hainan lightning, Haikou arrester, Haikou lightning protection and grounding. The SPD works: release lightning or concurrently can release the power system operating voltage energy, protect electrical equipment from transient overvoltage hazard, can truncated freewheeling, without causing the system is shorted to ground electrical installations. The arrester is usually connected between the live conductor and ground, and protection devices in parallel. When the overvoltage value reaches a predetermined operation voltage arrester immediate action, flows through the charge limit voltage amplitude, protective equipment insulation; normal voltage value, surge arresters and quickly restore the status quo ante, to ensure normal power supply. Arrester has the tubular valve two categories. Surge arresters into silicon carbide the arrester and metal oxide surge arresters (also known as zinc oxide surge arresters). Tube arrester is mainly used for the protection of substations, power plants into the line protection and line insulation weaknesses. Silicon carbide arrester is widely used in AC and DC systems, the protection of the insulation of the power generation, substation equipment. Zinc oxide arrester protection superior to silicon carbide arrester, are gradually replacing the latter, widely used in AC, DC system, to protect the insulation of the power generation, substation equipment, especially suitable for the effective grounding of the neutral point of 110 KV and above grid .
