Portable electric leakage detection terminal

Abstract

A portable electric leakage detection terminal comprises an insulating operating rod, a remote control electric telescopic rod and a transverse cylindrical shell, the shell comprises an upper shell and a lower shell which can be buckled up and down, the long edges of the rear sides of the upper shell and the lower shell are connected through a hinge, and remote control electronic locks are arranged on the long edges of the front sides of the upper shell and the lower shell. The lower end of the remote-control electric telescopic rod is rotatably connected with a lower shell left-end baffle, the top end of the remote-control electric telescopic rod is rotatably connected with an upper shell left-end baffle, and the bottom of the lower shell is vertically provided with an insertion groove into which the top end of the insulating operating rod can be inserted. The terminal has the beneficial effects that the structural design is reasonable, after the upper shell and the lower shell are buckled, a cable can be clamped, and threading openings in the two ends can be plugged through wire clamping plugs, so that the whole device is fixed to the cable, the device is prevented from sliding on the cable, and safety and reliability are improved; solar power supply is adopted, power supply efficiency is improved, heat dissipation effect is good, and detection accuracy and efficiency are high.

Description

technical field [0001] The invention relates to a portable leakage detection terminal. Background technique [0002] At present, in the low-voltage 380 / 220V three-phase four-wire power supply system, all branch lines and residential households are generally equipped with leakage protectors. Due to the aging of the lines, leakage protectors may be triggered by leakage, and the fault point cannot be timely and accurate. Excluded, directly affecting their own household electricity, many households removed the leakage protector and replaced it with a knife switch or an air switch. In this way, when the leakage current reaches a certain value, the leakage protector at the upper level will trip, and even the secondary main switch of the transformer will trip. Contents of the invention [0003] In order to solve the above technical deficiencies, the present invention provides a portable leakage detection terminal, which can detect the leakage current scheme online in real time, ...
