Problems solved by technology

[0003] However, in the actual construction process, there are often situations where it is necessary to extend and connect cables. In terms of cable connection, quick connectors are generally used for connection. Under the action of the electric field force, the high-voltage cable or quick connector may be broken down, resulting in poor electrical contact or overload and overload current, causing heating at the cable connection part. Due to factors such as poor ventilation and heat dissipation, it is easy to cause an abnormal increase in the local ambient temperature of the quick connector , resulting in dangerous accidents such as fire and explosion

Abstract

The invention provides a cable connector and a cable connection control device and belongs to the technical field of power cables. The cable connector comprises a hollow insulation casing, a high-voltage relay arranged in the insulation casing and plug assemblies which are symmetrically connected to the two ends of the insulation casing. According to the cable connector and the cable connection control device provided by the embodiment of the invention, a controller, a temperature sensor which is used for measuring temperatures of the plug assemblies connected to the two ends of the insulation casing and the high-voltage relay are arranged in the hollow insulation casing; if the temperatures of the plug assemblies exceed a set threshold value in a high-voltage cable operation process, the high-voltage relay can break connection between two high-voltage cables under action of the controller; thus, safety accidents of fire caused by abnormal increasing of local temperature at the cable connection position are avoided, loss is reduced, and safe operation of the high-voltage cables is guaranteed.

Description

technical field [0001] The invention relates to the technical field of power cables, in particular to a cable connector and a cable connection control device. Background technique [0002] In engineering construction, the safe and stable operation of high-voltage electrical equipment is the guarantee of safe construction. A cable, especially a high-voltage cable, is a special electrical device. During operation, the conductive part is wrapped in a closed insulating material, and a uniform induction electric field is formed inside, and the external touchable part is in a state of zero potential. A very safe electrical product. [0003] However, in the actual construction process, there are often situations where it is necessary to extend and connect cables. In terms of cable connection, quick connectors are generally used for connection. Under the action of the electric field force, the high-voltage cable or quick connector may be broken down, resulting in poor electrical c...
