Description

China Low Voltage Switchgear,switchboard

1.Product Overview

GGD low-voltage switchgear is suitable for power distribution system of AC 50 Hz, rated working voltage 380 V and

rated working current 3150 A in power plants, substations, and industrial enterprises, etc. It is used as lighting, electric energy

conversion, distribution and controlling of distribution equipment.
GGD low-voltage distribution cabinet is designed according to senior management of energy ministry, general electric power

users and requirements of design department. The device is a innovative type of low-voltage distribution cabinet that is in line

with the safety, economic, reasonable and reliable principles. The product has high capability of breaking, high thermal stability,

flexible electrical scheme, convenient combination, seriation, high practicability, innovative structure, high protection grade, etc.

It can be used as the upgraded replacement of the low-voltage complete switchgears.
The device conforms to IE439 < Low-voltage complete switchgear and control equipment >, GB7251 < Low-voltage complete switchgear> standards.

2.Main circuit scheme

Main circuit of GGD cabinet has 129 schemes and 298 specifications (excluding the derived schemes and specifications due to function change of auxiliary circuit or change of control voltage).

Wherein: GGD1 type has 49 schemes 123 specifications

GGD2 type has 53 schemes 107 specifications

GGD3 type has 27 schemes 68 specifications

3.Structure 

GGD adopts the general purpose cabinet body, its frame is made of 8MF cold forming sectional steel by means of partially welding and combination, the frame parts and special supporting parts are provided by the appointed manufacturer, so as to guarantee the cabinet accuracy and quality. The parts of general purpose cabinet is designed according to the module principle, and set with mounting hole of 20mm for module, with high common factor, to realize preproduction, shorten the manufacture period and improve the working efficiency.

4.Normal working environment:

Air temperature around No higher than 40ºC and lower than -5ºC
Average temperature No more than +35ºC within 24 hrs. Needs to drop the capacity according to actual conditions;
Altitude No more than 2000 m
Highest temperature +40ºC
Relative air humidity No more than 50%.Larger relative humidity is allowed when the temperature is relatively

low: ex. +20ºC 90%. Consider the frost effect due to temperature change accidentally;
the inclination of the device to the vertical of the ground is no more than 5 degrees, and the whole cabinets are in relatively

same level (conforms to GBJ232-82 standard)
The device should be installed in a place without violent vibration and impact, and no corrosion to its electric components
