8 Years Exporter Kyn28A-24 Armored Removable AC Metal Enclosed switchgear

Short Description:

XGN66-12 fixed metal-enclosed switchgear  is used for receiving and distributing electric energy in 3.6, 7.2, 12kv three-phase AC 50Hz systems, suitable for frequent operation occasions, and its busbar system is a single busbar (and can be derived single bus with bypass and double bus structure). The switchgear meets the requirements of the national standard IEC60298 (3-35kv AC metal-enclosed switchgear) and has two proposed “five-proof” locking functions.

Overview

This equipment is indoor metal armoring w ith drawable switchgear(hereafter refer to as switchgear.3.6-12 kilovolt three phasc AC50Hz single bus bar and the single bus bar section system’s omplete eletricity distribution euipment is used in the power plant,small and medium-sized penerator nower transmission,industryand mining business power distbution as well as electrical industry svstem’s seconc transformer substation’s electric take-over,power transmission and large-scale high pressure motor starting and so on.The purpose is to control,protect and monitor.This switch equipment is up to the standard oflEC 298GB3906 and can prevent the charge from pushing and pulling the breaker,fom opening and closing the breaker,from insulation with electricity by mistaken,from earthed switch closing the breaker, from opening the switchs interlock when it with eletricity mistakenly.It can not only use with VS1 vacuum circuit breaker, but with ABB Corporation’s VD4 vacuum circuit-breaker.It is indeed a kind of power distribution euipment with superior performance.

Structure introduction

The switch equipment is designed according to GB3906-91metal amoring seal switch equipmnent.The rectifier bocy is made up of the cabinet body and draw-out parts(namely handcart placed in the middle.See charter1.The cabinet divides into four separate rooms, the outer covering protection grade is IP4Xwhen each small room and the circuit breaker is openedthe protection grade is IP2X. It can suspend the inlet,outlet ine.cables inlet.outlet line and other function plan.After arranged and combinedit can beome each kind of plan form of the power distribution equipment.This switch equipnent may be installed and maintained from the frontage,therefore it may compose the dul arrangement back to back and be installed against the wall,improving the switch equipment’s security and flexibility and making full use of the occupying area.
