Zhegui Electric Medium Voltage Ring Main Unit Ring Network Switch Cabinet / Inflatable Cabinet

PRODUCT DETAILSZHRM6-12/24 fully insulated aerated cabinet has obtained the type test report in the National High Voltage Electrical Appliances Test Center and has been listed as a high-tech product in Zhejiang Province.Widely used in 10kV / 20kV power distribution system, urban and rural users of all types of power distribution system preferred switch products.The switchgear is modular unit mode, which can be combined according to different purposes;It is divided into two categories: fixed unit combination and expandable unit, which can meet the needs of various substations for flexible use of compact switchgear.The ZHRM6-12/24 fully insulated inflatable cabinet is a fully sealed system with all live parts and switches enclosed in a stainless steel housing.The whole switchgear is not affected by external environmental conditions, thus ensuring operational reliability and personal safety, and achieving maintenance-free.By choosing extensible busbars, any combination can be realized to achieve full modularity.Extended bus safety insulation and shielding, to ensure high reliability and safety.ZHRM6-12/24 pneumatic switchgear can also provide a TV-like automation solution, forming the concept of an intelligent switch and minimizing on-site installation and commissioning work.ZHRM6-12/24 fully insulated inflatable cabinet is divided into non-extensible standard configuration and extensible standard configuration.Because of the combination of full module and half module as well as its own expansibility, it has very special flexibility.ZHRM6-12/24 fully insulated aerated cabinet is in compliance with GB standard.The design life is more than 30 years for indoor (40 ° C) and outdoor (-50 ° C) operation.  TECHNICAL PARAMETERprojectunitsC moduleF moduleV moduleCB moduleLoad switchCombination electric appliancevacuum switchIsolation/grounding switchvacuum circuit breakerIsolation/grounding switchThe rated voltageKV121212121212Rated frequencyHZ505050505050Power frequency withstand voltage (phase/fracture)KV42/4842/4842/4842/4842/4842/48aLightning shock withstand voltageKV75/8575/8575/8575/8575/8575/85Rated currentA630infuse 1)630 1250/630 Breaking ability:       Rated closed loop breaking currentA630     Rated cable charging break currentA10     Rated short circuit closing current (peak)A5080    Rated peak tolerable currentkA50     Rated short-time tolerable currentkA/3520     Rated short circuit breaking currentkA 31.520 25 Rated transfer currentA 1700    Use the maximum current of the fuseA-125    Loop resistance-n≤300≤600    Mechanical lifenext500030005000200050002000Note: Depends on current rating of the fuse  PRODUCT FEATURESF6 gas in ZHRM6-12/24 fully insulated aerated cabinet is used as arc extinguishing and insulating medium.The switchgear is fully sealed and fully insulated.Bus, switch and live parts are completely enclosed in a stainless steel housing.The cavity is filled with SF6 gas of 1.4bar, and the protection level reaches IP67: the whole switch device is completely free from the influence of external environmental conditions, and can guarantee the normal operation of the switch even in the extreme circumstances such as short-term water flooding. The product is maintenance free for life.Switchgear has a perfect "five prevention" interlock device, completely eliminate the operation failure of personnel and equipment caused by human misoperation.All switchgear has a reliable safe pressure relief channel to protect the operator's safety even in extreme circumstances.Switchgear can be divided into fixed unit combinations and expandable unit combinations.Switchgear usually from the front in and out, but can also be installed in a different position to achieve the side out or side expansion.The size of the cabinet is easy to install, and can be suitable for small space and poor environmental conditions.Switchgear can be equipped with electric, remote control and monitoring devices according to different needs of users.COMPANY INFORMATIONWOORKSHOPContact UsCertifications SHIPPING PAYMEANTinfuse/* 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
