Cable head plugging out device used for ring main unit

Abstract

The present invention discloses a cable head plugging out device used for a ring main unit. The cable head plugging out device comprises a telescopic sleeve, a fixing sleeve and a cable head fixing device, a hydraulic device is arranged at the left end of the telescopic sleeve, and three fixing supporting legs which are in annular array distribution are arranged around the fixing sleeve. A first direction regulating disc is arranged at the left end of the cable head fixing device and is fixed to a first connecting column via a rotating shaft, a second direction regulating disc is fixed at the right side of the first connecting column and is fixed to a second connecting column via the rotating shaft, and a cable fixing head is fixed at the right side of the second connecting column. The cable head plugging out device used for the ring main unit of the present invention solves the problems that the equipment cannot be fixed in the ring main unit flexibly and stably, and the positions cannot be rotated flexibly to fix a cable head.

Description

technical field [0001] The invention relates to a cable head extraction device, in particular to a cable head extraction device for a ring network cabinet. Background technique [0002] The ring network cabinet is a group of high-voltage switchgear installed in the steel plate metal cabinet or made into an assembled spaced ring network power supply unit. Its core part uses load switches and fuses. It has simple structure, small size, low price, and The advantages of improving power supply parameters and performance and power supply safety, etc., the cable heads in the ring network cabinet are mainly connected by insertion. To ensure safety and avoid loose cable heads, generally the cable heads are inserted more firmly, which leads to ring network cabinets. It is more difficult to pull out the inner cable head. [0003] At present, the extraction of the cable head in the ring network cabinet is mainly done by manpower. Because the cable head is fixed on the ring network cabi...

AI Technical Summary

Problems solved by technology

[0003] At present, the extraction of the cable head in the ring network cabinet is mainly done by manpower. Because the cable head is fixed on the ring network cabinet for a long time, it is not easy to pull out. It usually requires many people to participate in the completion. During this process, the cable head is easily deviated due to force. At the same time, The space of the ring network cabinet is small, and the cable head is not easy to grasp. At the same time, the plug head needs to be shaken vigorously because it is not easy to pull out manually, which will cause the conductive rod in the plug head to often bend, deform, and break, causing damage, which is often time-consuming. It is laborious and not easy to complete, which wastes human resources, but the equipment used for cable head extraction on the market cannot be well fixed in different types of ring network cabinets, and at the same time, it cannot be flexibly rotated to fix the cable head
