HY5WS-10/30 oxide zinc arrester

Yueqing Deng Rui Electric Co., various specifications of the [HY5WS-10/30 oxide zinc arrester] products, providing professional [HY5WS-10/30 oxide zinc arrester] prices, models, pictures, factory direct supplier prices have obvious advantages, find [HY5WS-10/30 oxide zinc arrester] manufacturers, we chose Dengrui electrical, please contact us!

HY5WS-10/30, HY5WS-7.6/30 distribution type arrester for the protection system rated voltage 6KV power transformers, switchgear, box-type substation, power cable outlet header, the column of oil switches and other distribution equipment from the atmosphere andover-voltage damage.
Dengrui the electrical the arrester main products are:
Zinc oxide arrester, composite metal oxide surge arresters, drop arrester removable surge arresters, may cast a lightning arrester, line type arrester combined arresters, power plant type arrester, motor type arrester, distribution type arrester, capacitor type arrester, electrification Railway type arrester, the neutral point arrester low-voltage type arrester, motor type arrester, transformer neutral point arrester engine room arrester discharge counter, surge arrester line monitoring, the arrester disconnector, etc.; arrester Annex: JS-8; JSY -10; JCQ-C; the TLB thermal explosion type out of; arrester mounting bracket (surge arrester mounting plate), wire (from the conductive line), silicone rubber insulation sheathing
Select arrester must pay attention to the following two points:
Arrester grounding device must be based on the size of distribution transformers in accordance with the procedures required by the design and construction. 100 kVA and above with change, the requirements of the grounding resistance value must be less than or equal to 4 ohms; change below 100 kVA with requirements of the grounding resistance value shall not be greater than 10 ohms. Before the arrival of the thunderstorm season, carefully check the ground deflectors, the connection point to find the problem to be dealt with immediately.
Good lightning arrester selection off. The selected arrester should withstand the atmospheric over-voltage and over-voltage operation can be safe and reliable action; to withstand transient over-voltage attacks and grid single-phase ground fault malfunction occurs. I suggested that in the 10 kV distribution network to make use of zinc oxide surge arresters with series gaps. Zinc oxide arrester with series gap, due to the presence of composite gap to ensure that the valves only in the course of action of voltage protection, to withstand high voltage, and a very short time of its exposure to high-voltage. Pressure in the grid under normal circumstances, the sub-gap resistance valves withstand voltage value is very low, thus significantly delay the aging of the valves, deterioration, failure
