Distribution line automation terminal outdoor test line concentration box

Abstract

The invention relates to the technical field of distribution line automation terminals, and discloses a distribution line automation terminal outdoor test line concentration box, which comprises an insulation box body, a lower line fixing seat is fixedly arranged in the center of the top end of the insulation box body, and a needling electricity taking mechanism and a pressure fixing mechanism are respectively arranged on the front surface and the back surface of the lower line fixing seat. A bottom end wiring board is arranged in the insulation box body, and a plurality of inner wiring piles and a plurality of outer wiring columns are arranged on the bottom end wiring board. Under the combined action of a spring and a pressure plate, the pressure plate always tends to be downward, so that when the external binding post is not stably fixed, the external binding post is bounced off through the pressure plate, and the external binding post is separated from the lower power connection post, thereby ensuring that the internal wiring post and the external binding post are connected for electric conduction only when the external binding post is stably fixed; and when a worker unscrews the external binding post, power transmission to the external binding post is cut off immediately, so that the worker does not touch a conductive part by mistake during use, and the danger of electric shock is prevented.

Description

technical field [0001] The invention relates to the technical field of distribution line automation terminals, in particular to an outdoor test junction box for distribution line automation terminals. Background technique [0002] In the power network, the distribution network is the carrier of power supply. Its stability and security are directly related to the safety of power supply, which has important economic value and social significance. At the same time, distribution automation is also an important part of the smart grid. The distribution line automation terminal is one of the important core components of the distribution station automation system. It is widely used and plays an irreplaceable role. It is mainly used for line monitoring and protection of various distribution stations. [0003] In the detection process of the distribution line, it is usually necessary to detect a variety of different electrical parameters on the energized line, so as to jointly judge t...
