Product Details
1、 Product Overview
As the name suggests, high and low voltage distribution cabinets are distribution equipment used in power supply systems for energy distribution, control, metering, and cable connection. Generally, power supply bureaus and substations use high voltage switchgear,
Then, the low-voltage side of the transformer is stepped down and led out to the low-voltage distribution cabinet. The low-voltage distribution cabinet is connected to various power distribution panels, control boxes, and switch boxes. Inside, some switches, circuit breakers, fuses
A power distribution device that integrates protective devices such as buttons, indicator lights, instruments, and wires to meet the design functional requirements. Commonly known as high and low voltage switchgear or complete sets of high and low voltage electrical equipment.
2、 Model and meaning
3、 Normal usage conditions
1. The ambient air temperature shall not exceed+40 ℃, with no low pressure of+5 ℃, and the average temperature within 24 hours shall not exceed+35 ℃.
2. Atmospheric conditions: The air is clean, and the relative humidity does not exceed 50% at a maximum temperature of+40 ℃. Higher relative humidity is allowed at lower temperatures, such as 90% at+20 ℃, but temperature changes should be taken into account as condensation may occur accidentally.
3. The altitude shall not exceed 2000m.
4. This device is suitable for transportation and storage at temperatures between -25 ℃ and 55 ℃, and can reach+70C in a short period of time (not exceeding 24 hours). At these extreme temperatures, the device should not suffer any irreparable damage and should be able to function normally under normal conditions.
5. If the above usage conditions cannot be met, it should be resolved through negotiation between the user and the manufacturer.
6. When this device is used on offshore oil drilling platforms and nuclear power plants, a separate technical agreement should be signed.

5Cabinet structure
The basic mechanism of the switchgear cabinet is composed of C-shaped profiles assembled. C-shaped profiles are made by bending steel plates with E=25mm as the modular installation hole. All cabinet racks and inner partitions are treated with galvanized purification.The surrounding door panels and side panels are coated with high-voltage electrostatic spraying.
sixType of switchgear
1Power distribution cabinet (PC): EmaxMT, 3WN.AH.ME series and other circuit breakers can be used.2Electric Motor Control Center (MCC): Assembled from drawers of various sizes, the main switches of each circuit adopt high breaking plastic case circuit breakers or rotary load switches with fuses. Power factor automatic compensation cabinet (withManual, automatic, and remote power factor compensation devices
