10 KV metal oxide lightning arrester
Details:
10 KV metal oxide lightning arrester is the electric power system all kinds of electric equipment (transformer, reactor, generators, motors, PT, CT, circuit breakers, contactor, etc) insulation coordination foundation, the protection of the determined by lightning arrester performance power system all electrical equipment inside and outside of the insulation index (short-time current withstand voltage, lightning shock pressure and operating impact stress, etc.).
The product of the core work component is from zinc oxide mainly element metal oxide powder fire. It has excellent nonlinear v-Ann characteristics, steep wave fast response, the flow capacity. Have clearance product USES from blow gap, with pressure illuminate structure, and to reduce the discharge of dispersion, impact coefficient little.
Composite insulation coat adoption, and conform to the international power miniaturization product, secure, free maintenance trend of development. Organic polymer composite materials and traditional ceramic and glass and other inorganic material, it is characterized by small volume, light weight, bear the filthy, explosion-proof shock move from cleaning the advantages. Is integrated, modular in high pressure transmission and transformation equipment first lightning protection components.
Normal product normal use conditions as follows:
* environment temperature: no higher than + 40 ¡ãC, no less than 40 ¡ãC;
* altitude: no more than 2000 m;
* power frequency: 50 ¡À 2 Hz; 60 ¡À 2 Hz;
* earthquake intensity: 7 degrees below;
* with maximum sustained winds of 35 m/s;
* from cleaning the conditions: medium and the following areas unclean;
* to no clearance product, the industrial frequency voltage on long term shall not exceed lightning arrester continued operation voltage;
To have clearance product, installed point power frequency voltage increase short-term shall not exceed lightning arrester rated voltage.
Use for a long time in the following abnormal condition, lightning arrester need special production, when an order should inform:
* temperature or exceed altitude (plateau, tropical, cold, fully enclosed with electric furnace, etc, near the ark)
* use environment there is serious moisture or corrosive gas impurities (water, salt pan, chemical plants, etc.);
* strong ultraviolet ray radiation (plateau, strong sunshine drought areas etc.);
W * unclean area (mining face, construction site mining face, etc.).
