Ahg70V12/- /3 Solid Insulation Ring Net Cabinet Movement

Product overview:Solid insulated switch is the core of solid insulated ring network cabinet. It is an integrated design of vacuum circuit breaker or load switch, isolation switch and grounding switch. It has a compact structure and adopts front and back arrangement. Reduce the intermediate unnecessary transmission link, save labor, save parts, high transmission efficiency. The primary part adopts the APG automatic gel process, and the vacuum isolation chamber and the isolation and grounding switch of the primary part are completely sealed in special epoxy resin, which is used as the solid sealing pole unit with superior insulation and electrical properties. Solid insulated switch can be integrated as a module and switch cabinet assembly into different functional units; The operating mechanism of the switch and the operating mechanism of the isolation switch and the elastic operating mechanism of the main switch have been realized interlock, and the parts of the mechanism are less, reduce the unnecessary transmission link, high reliability, and the isolation switch can be electric operation according to the needs of users.. Pole unit integration, high climbing distance, with excellent electric field performance.. Using vacuum arc extinguishing chamber, knife and brake isolation, grounding switch.. The switch body has high protection grade and anti-condensation function.. Main bus outlet and cable outlet adopt standard European joint, easy to assemble cabinet, safe and reliable. Special epoxy resin insulation material.        a. High mechanical strength.        b. Good cracking resistance, thermal shrinkage, thermal conductivity and aging resistance.        c. The high glass transition temperature is greater than 110C, so that the insulation ability of epoxy resin does not decrease under the high                       temperature operating environment.  The isolation switch can be electrically operated according to the needs of users, which can truly realize the automation of distribution networkEasy maintenance, open the panel for parts replacement and line inspection.  Main Technical ParametersProjectUnitGircuit bresker unitLoad switch unitFuse assembly electrical unitRated voltageKV121212Rated frequencyHz505050Rated currentA630/1250630/1250Depends on the fuse current ratingRatedinsulationlevelPower frequency withstand voltage (phase to phase and relative)KV424242Power frequency withstand voltage (vacuum fracture, isolation fracture)484848Power frequency withstand voltage (control and auxiliary circuits)222Lightning impact withstand voltage (phase to phase and relative)757575Lightning impact withstand voltage (vacuum fracture, isolation fracture)858585Rated short-time withstand currentkA20(25)/4S20(25)/4S______Rated peak tolerable currentkA50(63)50(63)______Rated short-circuit closing currentkA50(63)50(63)Limited by the high woltage fuseRated short-circuit breaking currentkA20(25)20(25)Limited by the high woltage fuseRated transfer currentA____________1700Rated active load breaking currentA__________________Rated closed-loop breaking currentA630630______Internal arc test AFLR classkA/S20(25)/0.5S20(25)/0.5S______Partial discharge(1.2Ur)PC≤10≤10______Protection class (cabinet) IP4XIP4XIP4XMain circuit resistanceuΩ≤120≤120______Mechanical lifeCircuit breaker/load switchkA100001000010000solation/groundingswitch300030003000  Outline and mounting dimensions drawing: /* 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
