Abstract

The invention discloses a switch cabinet cable detection device and method, and the device comprises a cabinet body structure and a switch assembly, the switch assembly comprises a moving contact and a grounding contact, the cabinet body structure is provided with a cable incoming line connector and a withstand voltage detection connector, the cable incoming line connector is connected with an incoming line cable, and the withstand voltage detection connector is externally connected with a withstand voltage test device. A cable inlet connector is electrically connected with a moving contact, a withstand voltage detection connector is electrically connected with a grounding contact, when the switch assembly is in a grounding state, the withstand voltage detection connector and the cable inlet connector form a detection path, and it is ensured that an electrician can detect an inlet cable on the cable inlet connector from the withstand voltage detection connector. The incoming cable can be subjected to a withstand voltage test without being dismounted from the cable incoming connector, the dismounting time is shortened, the overall detection speed is improved, meanwhile, damage to the incoming cable and the cable incoming connector due to repeated dismounting is avoided, the insulativity of the incoming cable is protected, and the service life of the incoming cable is prolonged.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a detection device and a detection method for a switch cabinet cable. Background technique [0002] Existing switch cabinets need to be connected to external cables before use. When the external cables are connected to the switch cabinet, a cable connector needs to be connected to one end of the cable, so that it can be easily installed on the incoming cable sleeve of the switch cabinet. After the switch cabinet has been in operation for many years It is necessary to carry out insulation testing on the cable circuit. Usually, the cable connector is removed from the incoming cable casing first, and then the cable connector is connected to the pressure-resistant equipment. The cable connector is connected to the cable sleeve of the incoming line. Since the cable connector is connected to the cable, the overall weight is heavy, and installation and disassembly are troub...
