HY5WZ-51/134 oxide zinc arrester

Yueqing Deng Rui Electric Co., Ltd.supply various specifications of the [HY5WZ-51/134 oxide zinc arrester] products, providing professional [HY5WZ-51/134 oxide zinc arrester] prices, models, pictures, factory direct supplier prices have obvious advantages, find [HY5WZ-51/134 oxide zinc arrester] manufacturers, we chose Dengrui electrical, please contact us!


HY5WZ-51/134 zinc oxide arrester works
Zinc oxide arrester is the international ideal overvoltage protection, which uses zinc oxide resistor main components, compared with traditional silicon carbide arrester, has greatly improved the volt-ampere characteristic of the varistor to improve the flow capacity can be made no gap arrester. Therefore brought a fundamental change in the electrical structure characteristics.
HY5WZ-51/134 zinc oxide surge arresters under the normal operating voltage, the flow through the lightning current is only the microampere level, when subjected to the voltage, the arrester excellent non-linear characteristics played a role, the current flowing through the arrester thousands amps, surge arresters in a conduction state, the release of over-voltage energy, thus preventing the infringement of the over-voltage transmission and distribution equipment.

HY5WZ-51/134 zinc oxide arrester performance characteristics
1 HY5WZ-51/134 zinc oxide arrester lightning effects and ground has nothing to do, HY5WS2-17/50 zinc oxide surge arresters due to "potential" processing technology, and zinc oxide arrester lightning effects and equipment, whether ground has nothing to do, eliminating the need Install traditional arrester must be grounded trouble. Therefore easy to install, easy to use.
(2) to extend the life of the high electrical devices, grounded electrical appliances did not suffer lightning damage, but long-term impact of the lightning pulse electrical, resulting in various components of the electrical properties will be subject to certain destruction, TV, computers and other equipment service life. After installation, potential obo mine, dedicated, foolproof protection of electrical equipment.
3 the. HY5WZ-51/134 zinc oxide arrester body is small, but the protect equipment capable appliances are huge lightning current role of equipment or components heat damage. Heat energy and resistance, current, and the role of time is proportional to. Lightning strike current, while significant, but rarely the role of lightning internal resistance time (8 to 20 microseconds), the heat rarely, so it can protect the equipment itself will not be damaged. Moreover, zinc oxide arrester type in the current, it can withstand a high voltage of lightning, do not exceed the maximum current of zinc oxide surge arresters are exposed, even if the lightning voltage tens of thousands of volts or more are not afraid.

HY5WZ-51/134 zinc oxide arrester installation methods
Correct choice installation HY5WZ-51/134 zinc oxide arrester installation use and maintenance should pay attention
(1) prior to installation should proofread nameplate rated voltage of the system of zinc oxide surge arresters should be in line with the mount point of the system voltage;
(2) zinc oxide arrester fixed on the bracket, on terminals and high-voltage coupling the next terminal to be reliable grounding;
(3) can not be zinc oxide surge arresters as load-bearing supporting insulator should be as close as possible to the protected equipment installation, in order to reduce the impact of the distance of the protective effect;
(4) terminal zinc oxide surge arresters should be installed after the drop-out fuse, in order to facilitate the breaking of its protective effect, the transformer low voltage side of the low-voltage surge arresters should be installed to prevent the pros and cons of the transformation caused by the over-voltage damage to the transformer;
(5) the use of zinc oxide surge arresters should pay attention to the place of use of ambient temperature, zinc oxide arrester is not suitable for installation in vibration or serious foul and a place of serious corrosive gases;
(6) zinc oxide arrester operation before and at least two years of each run should do the preventive test;
(7), zinc oxide arrester brass double-layer bottom cover sealed and put into operation, every five years should be carried out preventive tests, measurement of leakage current, should be imposed on both sides of the arrester 10kV DC voltage (AC ripple less than ± 1.5%), leakage current meets its products specified value;
(8) The zinc oxide arrester grounding grounding procedures should meet the requirements.
