Yueqing Dengrui Electric Co., Ltd. supplies/high-voltage arresters. High-voltage arresters are on sale at special prices. If you are looking for/high-voltage arrester manufacturers, choose Dengrui Electric. Please call us for details! The following is a detailed introduction about / high voltage arrester
./ The most obvious electrical difference between high voltage arrester and valve arrester is zinc oxide arrester, which is small in size and has large leakage current. It is generally used on lines and medium and low voltage incoming lines in substations. end. Valve arresters are large in size and have small leakage current. They are generally used on the high-voltage side of substations and above, and are often installed on the frame. ./The high-voltage arrester is a metal oxide semiconductor non-linear resistor element with zinc oxide as the main component. The resistance is sensitive to voltage. When the voltage reaches a certain value, the resistance quickly turns on. Zinc oxide has the characteristics of good non-linear characteristics, large flow rate, low residual pressure level, fast response time and no afterflow.
./High-voltage arresters are small in size, light in weight (compared with porcelain jacketed arresters, the weight can be reduced by more than %), and have high tensile strength. They can be made into suspension types to save space and reduce costs.
Good stain resistance: The silicone rubber jacket has good hydrophobicity, the dirt layer on the surface accumulates slowly, and its hydrophobicity can also be transferred to the dirt layer. These characteristics can improve its dirt resistance and reduce maintenance. At the same time, silicone rubber, an organic polymer material, has good aging resistance and can meet the needs of long-term outdoor operation.
Good sealing performance: Made with special resin sealing technology, the sealing performance is good and it is not easy to form a penetrating air leakage channel that will cause the valve to get damp. Therefore, there is no possibility of an explosion caused by internal moisture in the high-voltage arrester.
The heat dissipation performance is good because there is no air gap inside. The heat of the valve plate is directly radiated outward through the solid, and the thermal conductivity of the solid is much larger than that of air, which is beneficial to increasing its load bearing capacity (i.e. leakage) capabilities) and lower operating temperatures to extend life.
The protective properties are not affected by the outside world because there is no spark gap inside, and the dirt on the jacket will not affect its protective properties. Since the high-voltage arrester has advantages that traditional arresters cannot match, it can not only improve the ability of the distribution system to prevent overpowering and reduce equipment accidents, but also reduce the accident rate of the high-voltage arrester itself, reduce installation costs, and prolong pre-testing. cycle (can be tested at least once every five years), reducing maintenance workload and improving power supply reliability. Test before installation of zinc oxide arrester. For type arresters, a volt megohmmeter can be used to measure the insulation resistance to ground before and after the test. The value must be greater than 1. Use a small current residual voltage tester or other suitable instrument to measure the test. The test data of arresters are slightly different for different use occasions. The test requirements and data are as follows (level)
