GCD low voltage draw out type switch cabinet

I. overview

GCD type low-voltage distribution cabinet, the Ministry of electric power planning and design authority of the project development of the product, by the North China Electric Power Design Institute and the joint development of our factory, designed for large generator sets low-voltage plant electricity matching. The electric characteristics of low-voltage cabinet factory, most components selection of domestic production and can be configured with neutral grounding fault detection device system. Can also be based on user needs, the selection of Schneider Inc low-voltage electrical components. The drawer unit of the cabinet is made of special aluminum alloy guide rail, which has the advantages of safety and reliability, flexible drawer drawer, strong interchangeability, beautiful appearance and practicality. Experts believe that: the product structure to achieve the advanced level of similar products in domestic production". The product can be used for three-phase AC 50 ~ 60HZ, 380V, 660V power system. The utility model is also suitable for other industrial and mining enterprises.

Two, the use of conditions

The ambient air temperature is not higher than + 40 C, and the average temperature in the 24h is not higher than + 35 degrees C, the lower limit of ambient air temperature is - 5 degrees C.

Atmospheric conditions: clean air, the relative humidity at the highest temperature is + 40 ~ C is less than 50%, allowing a higher relative humidity at low temperature for example: + 20 ~ C is 90%, but allowed due to temperature changes happen to appear moderate.

Altitude not exceeding 2000m.

Equipment installation shall not be more than 5 degrees of tilt.

The temperature switch cabinet suitable for transport and storage: - 25 ~ C ~ C ~ 55, in a short period of time (less than 24h) not more than 70 DEG C.

In case of failure to comply with the above normal operating conditions or special requirements, the user shall negotiate with the manufacturer.

Three, the main technical parameters

The cabinet adopts assembled structure.

Rated insulation voltage of main circuit is 500V, 1000V.

Rated voltage: the main circuit for AC 380V, 660V, auxiliary circuit for AC 380V, 220V, DC 220V, 110V.

The rated current of the horizontal bus is 3150A; the rated current of the rated current is 3150A, and the rated current is 630A.

Rated current (105KA, 1S) is rated as 15KA, 30KA, 50KA, rated peak withstａnd current of horizontal bus is 30KA, 63KA and. Peak withstａnd current rated short-time withstａnd current and the rated line unit, feeding unit, motor control unit and the vertical bus can withstａnd not less than rated short-time current and rated peak withstａnd current level of bus.

The switch cabinet to carry out the ZBK36001 "low voltage extraction complete sets of switchgear" standard, but also in line with the IEC439 "low voltage switchgear and control equipment," the relevant provisions.

Switch cabinet with the level of IP30, such as the user put forward higher requirements can also be negotiated solution.

Four, structure

The basic frame of the product is assembled and assembled structure, which is formed by the connection of the side frame and the cross beam by screws.

The frame and the parts are connected by screws so as to avoid the welding deformation and stress.

Frame column with 20mm module opening, each functional unit can be installed according to the electrical components, the chamber height can be 120 (80) mm modulus adjustment.

Each functional unit is isolated from each other to prevent the expansion of the fault. When the drawer is pulled out of the cabinet, the charged bodies in the cabinet are not exposed, and the utility model has the advantages of safety and reliability.

The drawer guide rail adopts a new three section guide rail. The rail bearing capacity is strong, the drawer is not necessary to take out to repair; with high precision, can guarantee the accurate positioning of one or two contact plug; functional units are working, test and separation of three distinct locations, each location has a mechanical positioning device; functional unit has good interchangeability.

Product separation wall (double side maintenance) and wall mounted two kinds of installation. The top of the product is a horizontal bus room, the front of the left is the functional unit compartment, the left rear is a vertical bus room, and the right side is the cable room.
