GCS type low voltage withdrawable switch cabinet

1. Purpose
The device is suitable for power conversion, distribution and distribution of power, distribution and motor control centers, capacitance compensation, etc. in low-voltage distribution systems such as power plants, substations, petrochemical departments, factories and mines, high-rise buildings, etc. For control.
It can meet the special needs of computer interfaces in power usage occasions such as power plants with large single-machine capacity and low-voltage power control centers and motor control centers in large-scale petrochemical industries.
The device complies with standards such as
Low-voltage complete switchgear and control equipment,
Low-voltage complete switchgear, and
Low-voltage withdrawable complete switchgear.
2. Product usage environment
The ambient air temperature should not be higher than +℃
and not lower than ℃
.
The average temperature within an hour shall not be higher than +℃
. If it exceeds, the capacity must be reduced according to the actual situation.
For indoor use, the altitude of the place of use must not exceed
.
The relative humidity of the surrounding air shall not exceed
when the maximum temperature is +℃
, and a larger relative humidity is allowed at lower temperatures, such as +
when it is
, it should be taken into account that condensation may occur occasionally due to temperature changes.
When the device is installed, the inclination with the vertical plane does not exceed
, and the entire cabinet row is relatively flat (
complies with
standards)
.
The device should be installed in a place where there is no severe vibration or impact and where the electrical components are not subject to undue corrosion.
When users have special requirements, they can negotiate with the manufacturer.

Four , Main circuit plan
The main circuit plan of the device consists of a total of specifications

, excluding plans and specifications derived from changes in the control and protection of the auxiliary circuit.
The main circuit plan is compiled after soliciting opinions from the design, manufacturing, testing and usage departments. It includes the needs of power generation, power supply and other power users. The rated operating current is
, suitable for Distribution transformers of
and below are selected.
In addition, the capacitor compensation cabinet is designed to meet the needs of power supply and consumption to improve the power factor, and the reactor cabinet is designed taking into account the needs of comprehensive investment (the main road scheme diagram is attached)
7. Structural Characteristics< br/>The structure of the device is made of section steel, and the structure adopts two structural forms: assembly and partial welding. There are mounting module holes on the main frame
.
The functional rooms of the device are strictly separated. The compartments are mainly divided into functional unit rooms, busbar rooms, and cable rooms. The functions of each unit are relatively independent.
The dimensions of the cabinet are as follows

Functional unit
A drawer is an independent functional unit.
Drawers are divided into four size series: half unit, one unit, two unit and three unit. The circuit current is
and below. The dimensions of a unit drawer are
(height) (
width) (
depth)
, the width of a half-unit drawer is
, and the width of a two-unit and three-unit drawer is The unit only doubles or triples in height, and the other dimensions are the same unit.
The drawers of the functional units can be easily interchanged.
Each cabinet of the device can be configured with a one-unit drawer or a half-unit drawer.
The drawer incoming and outgoing wires use the same number of chip connectors of the same standard according to the size of the loop current, generally one connector
The transfer between half the drawer and the cable uses a backplate structure adapter . The connection between the unit drawer and the cable room adopts a rod-type adapter.
The drawer panel has obvious signs for closing, breaking, testing, pulling out and other positions, and the drawer is equipped with a mechanical interlocking device.
