Product Description

This equipment is indoor metal armoring withdrawable switchgear(hereafter refer to as switchgear.3.6-12 kilo-volt three phase AC 50Hz single bus bar and the single bus bar section system's complete electricity distribution equipment is used in the power plant,small and medium-sized generator power transmission,industry and mining business power distribution as well as electrical industry system's second 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 of IEC 298,GB3906 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 switch's interlock when it with electricity 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 equipment with superior performance.

Use environmental conditions

1.Normal condition :
a.Surrounding air temperature:-10ºC ~+40ºC;

d.Earthquake:≤ 8 degree;
e.The surrounding air without corrosive or flammable gas or water vapour;
f.Without a lot of dirtiness and regular fierce vibration,under the severe condition,the intensity meets the first kind requirement. 2.Special working conditions :
Note:Please negotiate with us if your product is used beyond the range of above condition.

Structure Introduction

The switch equipment is designed according to GB3906-91 metal armoring seal switch equipment. The rectifier body is made up of the cabinet body and draw-out parts (namely handcart placed in the middle. See charter 1. The cabinet divides into four separate rooms, the outer covering protection grade is IP4X,when each small room and the circuit breaker is opened, the protection grade is IP2X. It can suspend the inlet, outlet line. cable's inlet, outlet line and other function plan. After arranged and combined, it can become each kind of plan form of the power distribution equipment. This switch equipment may be installed and maintained from the frontage,therefore it may compose the dual 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.
