Problems solved by technology

At the same time, due to the limited technical power of the electrician in power grid operation, when the ground leakage fault occurs, it is impossible to really find the ground leakage fault point or the troubleshooting takes a long time, and the power transmission cannot be resumed in time, which has caused great harm to the production and life of the people. It also affects the safe and normal operation of the power supply system
[0003] The existing leakage fault detector has a too traditional structure. During use, the detector cannot be protected against shocks according to the state of use, which may easily cause the detector to malfunction or be damaged, which increases the cost and brings troubles to the staff. Great inconvenience, therefore, in view of the above status quo, it is urgent to develop a leakage fault detector to overcome the deficiencies in the current practical application

Abstract

The invention relates to the technical field of power equipment, in particular to an electric leakage fault detector which comprises a shell, a detector body is arranged in the shell, and the electric leakage fault detector further comprises a protection frame which sleeves the detector body; the protective frame is located in the shell, and the protective mechanism is located in the shell and connected with the protective frame; wherein the protection mechanism comprises a control assembly and a damping assembly, the control assembly is connected with the shell and the protection frame and located at the bottom of the detector body, and the damping assembly is connected with the side wall of the shell and slidably connected with the side wall of the protection frame. The detector body can be subjected to damping protection according to the use state, so that the detector body is prevented from being broken down or damaged, the cost is saved, and convenience is provided for workers.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a leakage fault detector. Background technique [0002] In my country's power supply system, the distribution network has a large proportion, and the distribution network is widely distributed, with complex wiring and many branches. The probability of ground faults in the distribution network is very high, which can account for 80% of the total faults. Power outages due to ground faults are widespread. At the same time, due to the limited technical strength of electricians operating in the power grid, when a ground leakage fault occurs, the ground leakage fault point cannot be found or the troubleshooting time is long, and the power transmission cannot be restored in time, which has caused great harm to the production and life of the general people It also affects the safe and normal operation of the power supply system. [0003] The structure of the existing leakage ...
