Three-phase combined-type composite insulation metal oxide electric model lightning arrester (the "lightning arrester), mainly used for 3 KV, 6 KV, 10 KV 35 KV, voltage, high pressure system protection and electrical equipment and phase between low atmospheric overvoltage and insulation from operating over-voltage damage of a new type of combined-type overvoltage protection device.
Combined porcelain coat metal oxide lightning arrester since the 80 s, since its had success at home and abroad and the operation experience, especially its application in high pressure motor operating over-voltage protection, effective protective the alternate with and between facies over-voltage on the motor insulation damage. But because of its huge volume, especially in switchgear trapped within the year, which limit the use of it. New combined-type exchange composite insulation metal oxide lightning arrester adopts the special manufacture process, will lightning arrester and insulator combined into one whole, installation size and original lightning arrester completely consistent, the user to bring great convenience.
3 KV, 6 KV, 10 KV, 35 KV system combined exchange composite insulation metal oxide lightning arrester by three and only unit, only 1 in lightning arrester unit, to two of insulator. A and C phase will only alternate with lightning arrester unit 1 and 1 only insulator for A whole portfolio. B that will only alternate with lightning arrester element and 1 1 only to lightning arrester element in combination became a whole.
Lightning arrester of metal oxide non-linear resistors and insulator piled up into core body, use the special process, make its core body made whole again, to form a pressure molding the new process will the seal in silicone rubber, composition in overall lightning arrester. A.B.C three-phase lightning arrester respectively in the central installation wires. The structure of the lightning arrester is combined-type composite insulation metal oxide lightning arrester the optimal structure scheme, all metal use stainless steel materials, and crude oil combined traditional porcelain coat metal oxide lightning arrester, compared with the following excellent properties:
1. The excellent insulation performance; (high flash collaterals voltage)
2. Resistance to corrosion. The anti-aging, high temperature resistant, small volume, light weight,
3. Explosion-proof performance is good, be able to bear or endure corrupt performance is strong, protect the outstanding performance;
4. Silicon rubber molding sex good, lightning arrester easy realize reliable seal, no start to copy into approach;
5. Easy installation, cover an area of an area small.
Lightning arrester three-phase high-pressure termination in the online, only three central 0 points through the alternate with lightning conductor is linked together, form by ya ya connection, the subject of neutral connection series lightning arrester element D, lightning arrester element D below the ground, forming a complete phase-phase, phase-the protection of the system, when a crisis in the operation of electric equipment of the insulation and the atmosphere, overvoltage overvoltage due to metal oxide non-linear resistors role, limiting the protected overvoltage in electrical equipment.
