Live fast plug-in device for cable elbow joint and method

Abstract

The invention discloses a live fast plug-in device for a cable elbow joint and method. The live fast plug-in device for a cable elbow joint is applied between a switch box and a to-be-connected cable to conduct the power line on the switch box and the to-be-connected cable. The live fast plug-in device comprises a sleeve and a plug, wherein the sleeve is arranged on the switch box and comprises a conductive rod and a first insulating jacket, the conductive rod is electrically connected with the power line of the switch box, the first insulating jacket coats the outer surface of the conductive rod, and the top end of the conductive rod is provided with a plug-pull hole; and the plug comprises a plug-pull rod and a second insulating jacket, the second insulating jacket coats the outer surface of the plug-pull rod, the tail end of the plug-pull rod is crimped with the to-be-connected cable, the head end of the plug-pull rod is provided with a plug-pull part fit with the plug-pull hole, an accommodating hole exists between a plug-pull part and the second insulating jacket, and when the plug-pull part is plugged in the plug-pull hole, the accommodating hole sleeves the outer surface of the first insulating jacket in a matched mode. quick plug-in between the to-be-connected cable and the switch box can be realized, live operation can also be realized, and the phenomenon that power demands are affected by power failure does not happen.

Description

technical field [0001] The invention relates to a cable elbow charged fast plug-in device and method, and belongs to the technical field of cable elbows in 10kV switch boxes. Background technique [0002] The design of the 10kV switch box and docking box in the existing distribution network is a bolt-type outlet pile head. When connecting the cable to be connected to the power line on the switch box or the docking box, the cable to be connected is usually crimped to the elbow-shaped cable head first. Then connect the elbow cable head to the outlet pile head through bolts. The applicant found at least the following problems in the actual application of the above structure: 1. It is often necessary to turn off the power supply first before wiring operations can be carried out. However, power outages may have adverse effects on some equipment or users; 2. The installation is cumbersome and the wiring efficiency Low. Contents of the invention [0003] The technical problem t...
