GCL/K-0.4 type low voltage withdrawable switch cabinet
GCL/K-0.4 type low voltage withdrawable switch cabinet
Overview
Model GCL/K-0.4 withdrawable low-voltage switchgear (hereinafter simply referred to as device) is designed and developed by our company according to the technical level and structural characteristics of withdrawable low-voltage switchgear at home and abroad, and is extracted through the national CCC demonstration Type switchgear, referred to as (TTA). It complies with the national standard GB7251.12-2013 "low-voltage switchgear", the national professional standard ZBK36001-89 "low-voltage withdrawable switchgear" and the international standard LEC439.
This device is suitable for AC 50Hz, rated working voltage of 380V, working current of 2500A and below three-phase five-wire power grid, used in power generation, transmission and distribution systems as power lighting, power conversion, protection control and other occasions.
Working environmental conditions
1. For indoor installation.
2. The ambient air temperature is not higher than +40℃, not lower than -5℃, and its average temperature is not higher than +35℃ within 24 hours.
3. No explosive gas, corrosive gas and conductive dust.
4. The relative humidity does not exceed 50% when the morning high temperature is +40℃, and higher relative humidity is allowed at lower temperatures, such as 90% at +20℃, but it should be taken into account that it may be possible due to temperature changes Condensation may occur accidentally.
5. The altitude does not exceed 2000m.
6. The temperature during transportation and storage can be in the range of -25℃~+55℃, and the temperature can reach +70℃ in a short time (no more than 2h).

Structure characteristics:
The 8MF cold-rolled section 1, the framework of the basic components of the. Profile the second side respectively, modulus of 20ram and 100mm diameter 9 mounting hole, thus the frame assembly is convenient and flexible.
2, the cabinet body is divided into functional unit cell, cable chamber, busbar chamber, between each cell with steel plate are separated, each room is relatively independent.
3, the height of the drawer unit module for the 220mm, is divided into 1/2 units, 1 units, 2 units, 3 units of four size series.
4, the drawer changes only in the height of the size of the change, its width, the depth of the same size. The drawer of the same function unit has good compatibility.
5, the four drawer unit can be assembled in a single cabinet, but also can be used for mixing assembly. The drawer of the 1/2 unit must be arranged in a group.
Reliable mechanical interlock device 6, a drawer unit in only when the main circuit breaker is disconnected to open the drawer unit of the compartment door and the drawer to pull out. The drawer has three distinct positions, which are connected, tested and separated.
7, the device for the cabinet before the operation, after the cabinet outlet, cabinet maintenance type. The horizontal bus bar is installed in the upper part of the cabinet. According to a system circuit diagram, the level of the bus can be set to the front of the bus or after the confluence.
