Hy5 (10) W with Bracket Disconnector (Or Outlet) Composite Jacket Gapless Arrester Surge Arrester

Product DescriptionSurge arrester is a kind of overvoltage protector, which is mainly used to protect various electrical equipment (transformers, switches, capacitors, wave arresters, transformers, generators, motors, power cables, etc.in power systems, railway electrification systems, and communication systems. ) is protected from atmospheric overvoltage, operating overvoltage and power frequency transient overvoltage, etc., and is the basis for the insulation coordination of power systems.The core element (resistor sheet) of the metal oxide arrester adopts an advanced formula based on zinc oxide, which has very excellent nonlinear (volt-ampere) characteristics, that is, under normal operating voltage, the current passing through is only microampere level. , When subjected to overvoltage, the passing current reaches thousands of amperes instantaneously, making the arrester in a conducting state and releasing overvoltage energy, thereby effectively limiting the damage of overvoltage to power transmission and transformation equipment.The traditional SiC arrester has the disadvantages of high steep wave discharge voltage caused by steep wave discharge delay, and high operating wave discharge voltage due to large operating wave discharge dispersion. The zinc oxide arrester has the advantages of good steep wave response characteristics, no delay to the steep wave voltage, low operating residual voltage, and no discharge dispersion. The protection margin of steep waves and operating waves is greatly improved, and in terms of insulation coordination, the protection margins of steep waves, lightning waves and operating waves can be nearly the same, thus providing the best protection for power equipment..The composite jacket metal oxide arrester adopts the overall injection molding and two-end encapsulation process, with good sealing performance, excellent explosion-proof performance, pollution resistance, no cleaning, and can reduce the occurrence of wet flash in foggy weather, electric corrosion resistance, anti-aging, small size, light weight , easy to install and maintain. It is a replacement product of porcelain sleeve arrester.Model DescriptionProduct technical parameters and selectionProduct Structural features and scope of use1.

The arrester should be stored in a clean and dry room before installation and use. Must not be corroded by corrosive gases or liquids.2. Before the arrester is put into operation, a preventive test should be carried out. After being put into operation, it should also be regularly (10KV and below arrester once every 5 years, 35KV and above arrester once every 2 years)Do the following test and compare with the data before operation with reference to the attached table:a. Measure the insulation resistance of the arresterb. Measure the DC 1mA voltage of the arresterc. Measure the leakage current of 0.75 times DC 1mAProduct detailsProducts real shotA corner of the production workshopProduct packagingProduct application case /* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
