Power Supply Cabinet Withdrawable Complete Switchgear Stable Performance

Product Description

power supply cabinet withdrawable Complete Switchgear

Introduction

　Designed and researched by joint design group of two ministries in accordance with requirements of industrial authority, wide electric users and design organizations, GCS model low-voltage withdrawable complete switchgear is a low-voltage withdrawable-type switch cabinet that is in compliance with situations of China, features high technical performance index, can adapt to demand of electric market development and compete with existing imported product. The device applies to power distribution system of industries such as power plant, petroleum, chemical, metallurgy, textile and high building. It is used as low-voltage complete power distribution device for power distribution, concentrated motor control and reactive power compensation of power generation and power supply system of 3-phase AC frequency 50 (60) Hz, rated operating voltage 380V (400V)/(660V) and rated current 4000A and below in large-size power plant and petrochemical system where autorotation degree is high and interface with computer is required.

Environmental Conditions for Product Use

　　- Ambient air temperature should be no more than +40℃ and no less than -5℃, and average temperature within 24h should be no more than +35℃.

　　- Altitude should be 1000m, users of high altitude region should indicate altitude upon ordering, and the product can meet requirement of user for altitude below 4000m.

　　- Relative humidity of ambient air should be no more than 50% under the highest temperature +40℃, and larger relative humidity is allowed under low temperature (for example: 90% under temperature of +20℃).

　　- he inclination from vertical plane should be no more than 5°upon installation of equipment.

　　- Equipment should be installed at location free from violent shock and impact, and location free from corrosion of electric appliance component.

　　- User can negotiate with manufacture to find out solution in case of special requirements.

Product Features

- Framework adopts 8MF cold rolled section, of which two sides are configured with installation holes of modulus 20mm and 100mm, so that framework assembling is flexible and convenient.

　　- Lateral frame assembling mode of framework is designed as two types, full assembling structure and partial (lateral frame and cross beam) welding structure for selection by user.

　　- All functional compartments of switch cabinet are separated from each other, and are divided into functional unit compartment, busbar compartment and cable compartment. Functions of all compartments are relatively independent. Design of cable compartment realizes very convenient upper/lower incoming and outgoing of cable.

　　- Horizontal busbar adopts rear horizontal arrangement mode so as to enhance electrodynamic force resistance of busbar, which is a fundamental measure to realize high short-circuit strength of main circuit.

　　- Modulus of drawer height is 160mm. Drawer change is limited to change of height dimension only, while its width and depth dimension remain unchanged. Drawer of identical functional units features excellent interchangeability. Rated current of unit circuit is 630A and below.

　　- Drawer panel features prominent marking of open, close, test and drawn positions. Drawer unit features mechanical interlock unit.

　　- Incoming/outgoing line of drawer should adopt different number of plug-in components of slice architecture of the same specification as per electric current size. The switchover between unit drawer and cable compartment should adopt identical size of bar type or tubular type structure ZJ-1 switchover parts as per classification of current. The switchover between 1/2 unit drawer and cable compartment should adopt backboard structure ZJ-2 switchover parts
