Pad Mounted Switchgear - GGD AC Low-Voltage Power Distribution Cabinet – Xinneng Detail:

Scope of Application

GGD AC low-voltage power distribution cabinet is suitable for power users such as power plants, substations, industrial enterprises and other power users as AC 50HZ, rated working voltage 380V, rated current to 3150A power distribution system as power, lighting and power conversion equipment , Distribution and control. The product has high breaking capacity, rated short-time withstand current up to 50KAa, flexible circuit scheme, convenient combination, strong practicability, and novel structure. This product is one of the representative products of the assembled and fixed panel switchgear in my country.

This product complies with IEC439 “Low-Voltage Switchgear and Control Equipment”, GB7251.12-2013 “Low-Voltage Switchgear and Control Equipment Part 2: Complete Power Switches and Control Equipment” and other standards.

GGD AC low-voltage power distribution cabinet is suitable for power users such as power plants, substations, industrial enterprises and other power users as AC 50HZ, rated working voltage 380V, rated current to 3150A power distribution system as power, lighting and power conversion equipment , Distribution and control.

Environmental Conditions

1. The ambient air temperature is not higher than +40℃ and not lower than -5℃. The average temperature within 24 hours shall not be higher than +35℃.

2. For indoor installation and use, the altitude of the place of use shall not exceed 2000m.

3. The relative humidity of the surrounding air does not exceed 50% when the highest temperature is +40℃, and a higher relative humidity is allowed at a lower temperature: (for example, 90% at +20℃), it should be considered that the temperature may change Accidental impact of condensation.

4. When the equipment is installed, the inclination from the vertical plane should not exceed 5°.

5. The equipment should be installed in places where there is no severe vibration and impact, and places where electrical components are not corroded.

6. When the user has special requirements, it can be resolved through consultation with the manufacturer.

2. Auxiliary circuit scheme

The design of auxiliary circuit is divided into two parts: power supply plan and power plant plan.

3. Main bus

When the rated current is 1500A and below, a single bronze bus is used. When the rated current is greater than 1500A, double-bronze bus is used. The overlapping surfaces of the busbars are all treated with tin lining.

4. Selection of electrical components

a. The GGD cabinet mainly adopts more advanced electrical components that can be mass-produced in China. Such as DW17, DZ20, DW15, etc.

b. The 1ID13BX and HS13BX rotary-operated knife switches are special components designed by NLS to meet the needs of the unique structure of the GGD cabinet. It changes the operation mode of the mechanism and retains the advantages of the old products. It is a practical new type of electrical component.

c. For example, when the design department selects new electrical components with better performance and more advanced technology according to user needs, because the GGD cabinet has good installation flexibility, it will generally not cause manufacturing and installation difficulties due to updated electrical components.

d. In order to further improve the stability of the circuit, the bus support of the GGD cabinet adopts a dedicated ZMJ type combined bus clamp and insulating support. The busbar clamp is made of high-strength, high flame-retardant PPO composite material, with high insulation strength, good self-extinguishing performance, and unique structure. It can be easily combined into a single busbar or double busbar clamp by adjusting the building block. The insulating support is a sleeve-type molded structure with low cost and high strength, which solves the defects of insufficient creepage distance of old products.

Order Instructions

When ordering, the user should provide the following data:

1. The full model of the product (including the main circuit scheme number and the auxiliary circuit scheme number).

2. The main circuit system combination sequence diagram.

3. Electrical schematic diagram of auxiliary circuit.

4. List of components in the cabinet.

5. Other special requirements that are inconsistent with the normal use conditions of the product.
