Portable electric leakage monitoring device for low-voltage power distribution area and use method of portable electric leakage monitoring device

Abstract

The invention discloses a portable electric leakage monitoring device for a low-voltage power distribution area and a use method thereof, belongs to the technical field of electric leakage monitoring, and aims to solve the problem that electric leakage monitoring in the power distribution area is mostly realized through an electric leakage protection switch mounted in the power distribution area. In the prior art, the real-time condition of leakage current and the control action of a leakage protection switch cannot be checked, so that electric power workers cannot conveniently make corresponding emergency processing schemes in time, the system comprises a current acquisition module and a leakage monitoring cloud platform, and the terminal of the current acquisition module is connected with a current information monitoring module; the leakage current condition in the low-voltage distribution area is timely transmitted back to the leakage monitoring cloud platform through the data transmission module, the leakage monitoring cloud platform classifies and gathers the leakage current information, gives out a corresponding alarm, and stores the specific information of the leakage current. Therefore, an electric power worker can know the leakage current condition in the low-voltage power distribution area in time and make a timely emergency processing scheme.

Description

technical field [0001] The invention relates to the technical field of leakage monitoring, in particular to a portable low-voltage power distribution station area leakage monitoring device and a method for using the same. Background technique [0002] Leakage monitoring: that is to control the leakage situation in the distribution station area through the leakage protection switch. The action principle of the leakage protection switch is to use the zero-sequence current transformer to detect the electric shock / leakage current signal generated when the human body is shocked, and then send this signal to the electric shock / leakage current signal. To the detection and comparison circuit composed of electronic components and even special ICs, in order to drive the opening and power-off coil to make the mechanical mechanism related to the leakage protection switch act to cut off the power supply, so as to ensure personal safety and circuit safety in the distribution station area; ...

Problems solved by technology

[0003] At present, the leakage monitoring in the distribution station area is mostly realized by the leakage protection switch installed in the distribution station area. Because the existing technology cannot check the real-time situation of the leakage current and the control action of the leakage protection switch, resulting in It is inconvenient for electric power workers to make corresponding emergency treatment plans in a timely manner. For this reason, we propose a portable low-voltage distribution station area leakage monitoring device and its use method to solve the above problems
