What are the requirements for maintenance of wiring terminals

What are the requirements for terminal maintenance? Reasonable maintenance of wiring terminals is very important. What are the requirements for wiring terminal maintenance?

The general installation environment requirements for wiring terminals are: lower ambient temperature of -5 ℃ and higher ambient temperature of 40 ℃. Terminal blocks are used for the convenience of connecting wires. They are actually a metal piece enclosed in insulating plastic, with holes at both ends for inserting wires and screws for fastening or loosening. For example, two wires sometimes need to be connected and sometimes need to be disconnected. In this case, they can be connected with terminals and can be disconnected at any time without the need to weld or wrap them together, which is very convenient and fast. The UK terminal block is suitable for a large number of wire interconnections. In the power industry, there are specialized terminal blocks and terminal boxes, which are full of terminal blocks, single-layer, double-layer, current, voltage, ordinary, interruptible, and so on. A certain crimping area is used to ensure reliable contact and sufficient current flow. With the increasing level of industrial automation and stricter requirements for industrial control, the usage of terminal blocks is gradually increasing. With the development of the electronics industry, the range and variety of terminal blocks are increasing.

A large number of studies have shown that the failure rate of wiring terminals increases exponentially with the increase of temperature, and the service life decreases exponentially with the increase of temperature. When the ambient temperature rises by 10 ℃, the service life of the wiring terminal board will be halved.

The operation of the wiring terminals is closely related to the cleanliness of the environment.

Winter is a period of frequent occurrence of wiring terminal failures. Only through good maintenance and management can we reduce the occurrence of equipment system failures in enterprises. Users must pay attention.

When repairing high-voltage wiring terminals in winter, attention should be paid to the temperature of the installation environment of the wiring terminals, and the internal dust discharged from the wiring terminals should be cleaned regularly to ensure the smoothness of the cooling air circuit. Strengthen inspections and improve the surrounding environment of wiring terminals, motors, and circuits.
