Internal Electrical Distribution Network

Internal Electrical Distribution Network refers to an electrical network used for distributing, transmitting, and controlling electrical energy within a device, system, or building. This network typically consists of components such as wires, cables, circuit breakers, switches, sockets, and distribution panels, aimed at ensuring safe and efficient delivery of electrical energy to various points of use. The following is a detailed analysis of the Internal Electrical Distribution Network:

1、 Definition and Function

definition:

Internal Electrical Distribution Network refers to an electrical network used for distributing, transmitting, and controlling electrical energy within a limited scope (such as equipment, systems, or building interiors).

Function:

Electricity allocation: Allocate input electricity to various power points or devices according to demand.

Electricity transmission: Electricity is transmitted from distribution points to consumption points through components such as wires and cables.

Electric energy control: Control and protect electric energy through components such as circuit breakers and switches to ensure electrical safety.

2、 Structure and Composition

Input end:

It usually includes components such as power supply lines, main switches, or circuit breakers, used to receive external power and control the on/off of the entire internal electrical distribution network.

a distribution board:

The distribution panel is the core component of the internal electrical distribution network, used to distribute input electrical energy to various branch circuits.

Multiple circuit breakers or switches are usually installed on the distribution panel to control and protect various branch circuits.

Branch circuit:

A branch circuit is a circuit that originates from a distribution panel and is used to connect various electrical points or devices.

Each branch circuit is usually equipped with appropriate components such as wires, cables, and sockets.

Electricity consumption point:

Electricity point refers to the location or equipment inside a device, system, or building that requires electricity.

Electricity points are usually connected to branch circuits through components such as sockets and plugs.
