Three-phase combined gapless metal zinc oxide and metal oxide arrester with series gap
Three-phase combined organic jacketed metal oxide lightning arresters are protection electrical appliances used to protect the power transmission and transformation equipment and motor insulation of neutral point ineffective grounding systems at voltage levels of 35kV and below from damage caused by overcurrent. Because of its novel structure and the excellent volt-ampere characteristics of zinc oxide resistors, the protection performance, reliability and life of the product are greatly improved. The actual operation proves that in addition to limiting atmospheric overvoltage, it can effectively limit the phase-to-phase and phase-to-phase overvoltage caused by the vacuum switch, and achieve the purpose of protecting electrical equipment insulation and vacuum-phase phase-to-phase flashover. Due to its excellent protection characteristics, a three-phase combined arrester can replace six ordinary arresters. This product is suitable for indoor and outdoor use, the ambient temperature is -40 ℃ ~ + 40 ℃, and the altitude does not exceed 2000m. Its technical performance is shown in the following table, and its external structure, installation dimensions and wiring methods are shown in the attached drawings. Main parameters of three-phase combined gapless metal oxide arrester Technical parameters Product model system Nominal voltage arrester rated voltage Voltage arrester continuous operation voltage Residual voltage operation impact under lightning impulse current ...
