Problems solved by technology

According to the above structural description, it can be seen that the distribution network intelligent sensor needs at least two locking mechanisms, one for locking the cable and one for closing the upper and lower casings, but in order to ensure the firmness of the cables and the upper and lower casings, generally Both will tighten the crimping locking mechanism and connecting mechanism, resulting in excessive stress on the upper and lower housings, which may cause deformation of the housing, resulting in the hidden danger of equipment falling off the cable

Abstract

The invention discloses a power distribution network fault indicator. The power distribution network fault indicator comprises an upper shell and a lower shell, cable grooves are formed in the opposite sides of the upper shell and the lower shell. An upper pressing sheet is arranged in the cable groove of the upper shell; a lower pressing sheet is arranged in a cable groove of the lower shell; a guide rail is arranged between the upper shell and the lower shell, a lead screw is arranged in the guide rail, threads on the lead screw is meshed with threads in the upper pressing piece, the upper pressing piece is driven to move in the extending direction of the lead screw through rotation, the lower pressing piece is fixedly connected with the lower shell through a bolt, and non-rigid connection is formed between the upper pressing piece and the upper shell.

Description

technical field [0001] The invention relates to the technical field of distribution network intelligent monitoring, in particular to a distribution network fault indicator. Background technique [0002] The distribution network directly connects with users, and its reliable power supply capacity and power supply quality not only directly reflect the economic benefits of power companies, but also have immeasurable social benefits. As an important content of distribution automation, automatic fault location of distribution network has a great impact on improving the reliability of power supply, and has also received more and more attention. [0003] A variety of fault indicators for distribution networks have been disclosed in the prior art. For example, CN20740843U discloses a distribution network fault indicator, which includes a current transformer, an upper shell, and a lower shell . From the structure of the device, it can be seen that the distribution network fault ind...
