Distribution cabinet

A distribution cabinet is an important equipment used for power distribution and control in an electrical system.

A distribution cabinet is an important equipment used for power distribution and control in an electrical system. It is typically installed at the power supply point of the electrical system and is responsible for receiving power from transformers or generators and distributing it to different circuits and devices.

A distribution cabinet typically consists of the following components:

1. Main Circuit Breaker (Main Switch): Used to control the power supply of the entire system, it can be operated manually or automatically.

2. Fuses or Circuit Breakers: Used to interrupt the current in a circuit to protect the circuit and devices from overload or short circuits.

3. Current Transformers: Used to monitor the magnitude of current and trigger protective devices when necessary.

4. Voltage Transformers: Used to monitor the voltage magnitude to ensure that the voltage remains within a safe range.

5. Control System: Used to monitor and control the operation status of the distribution cabinet, which may include functions such as a Human-Machine Interface (HMI).

6. Protection Devices: Used to protect circuits and devices, such as overload protection and short circuit protection.

7. Grounding System: Used to ensure the safe operation of the system and prevent accidents like electric shocks.

The design and installation of distribution cabinets must comply with relevant electrical safety standards to ensure the reliability and safety of the system. Different types of distribution cabinets are suitable for different scenarios, such as residential buildings, commercial facilities, industrial plants, etc.
