What is an electrical connection section?

An electrical connection refers to the use of disconnectors in electrical installations.

Separate from other electrical installations.

An electrical unit of the power distribution device is equipped with an isolation switch that can be clearly segmented, and when a partial power failure is overhauled between these isolation switches, as long as safety measures are applied on the circuit breaker side or the side to be repaired at each isolation switch, the operation safety can be guaranteed.

For example, high-voltage bus bars or transmission lines, which can be clearly separated from each end of the system in all directions by disconnectors, can be called an electrical connection part.

Mistake. The so-called electrical connection part refers to the part of the electrical device that can be separated from other electrical devices by the isolation switch (knife switch).

1) In the electrical installation, the zhi part that can be separated from other electrical devices can be separated by the isolation switch (knife switch).

2) DC bipolar deactivation, converter transformer and all HVDC equipment can be regarded as an electrical connection part.

3) DC unipolar operation, the converter transformer, valve hall, DC field equipment, and water cooling system of the deactivated pole can be regarded as an electrical connection part. The bipolar common area is the operating equipment.

Electrical connection refers to the collection of all electrical circuits in an electrical product, including power connection components such as power plugs, power terminals, etc., power cords, internal wires, internal connection parts, etc.; In the narrow sense, electrical connections simply refer to all the ways in which different conductors are connected within a product.

Electrical connections include: terminal blocks, junction boxes, heavy-duty connectors, cables, cable glands, safety barriers, contacts, etc. For the sake of terminology, the term "electrical connection" generally refers to the electrical connection in the narrow sense, while the use of electrical connection components refers to the electrical connection in the broad sense.

Generally, according to the location of the electrical connection components, the electrical connection components in electrical products can be divided into two parts: external electrical connection components and internal electrical connection components. External electrical connection components refer to the electrical connection components on the outside of the product housing, which are not included in the protection of the product housing and must meet the corresponding shock protection requirements separately. The internal electrical connection components refer to all the electrical connection components inside the product shell, and these electrical connection components are included in the protection of the product shell, so they generally only need to meet the corresponding functional insulation requirements.

Electrical connections include: terminal blocks, PCB connectors, industrial connectors, junction boxes, heavy-duty connectors, cables, cable glands, safety barriers, contacts, etc. For the sake of terminology, the term "electrical connection" generally refers to an electrical connection in a narrow sense, while the use of electrical connection components refers to an electrical connection in a broad sense.

Applications: Electrical connections are widely used in electronics, electrical, industrial production, infrastructure, chemical industry, ports, machinery, national defense, industrial control and other fields.
