Portable electric leakage safety detection device

Abstract

The invention discloses a portable electric leakage safety detection device. The portable electric leakage safety detection device comprises a device body, a wire clamp is connected to the top of the device body through a rotary knob, supporting arms are symmetrically arranged at the lower end of the rotary knob in a clamping mode, a restoration spring is connected between the two supporting arms, and a transformation module is arranged at one side of the bottom inside the device body. According to the portable electric leakage safety detection device, high voltage is generated mainly through the transformation module, then the wire clamp is clamped on the part to be detected of a cable, whether electric leakage occurs on the part or not is judged through a flowing current value, when the wire clamp is clamped on the cable, the rotary knob is clamped in a toothed groove, when the detection device is not in use, the wire clamp does not need to be held by the hand, the possibility of an electric shock is reduced, a connecting buckle is further arranged at the back of the detection device, an insulating telescopic rod can be inserted on the connecting buckle in a clamping mode, and in this way, when some high wire sections and dangerous wire sections are detected, since the sections are far away from the human body, the portable electric leakage safety detection device is safer.

Description

technical field [0001] The invention relates to the technical field of electric power maintenance tools, in particular to a portable electric leakage safety detection device. Background technique [0002] The leakage detector is used to measure the leakage current irrelevant to work produced by the working power supply (or other power supply) of electrical appliances through insulation or distributed parameter impedance. Its input impedance simulates the impedance of the human body. Leakage detector is mainly composed of test power supply, impedance conversion, range conversion, AC-DC conversion, indication and sound and light alarm circuit. [0003] However, when the existing leakage detector detects the leakage of the cable line, because it needs to be hand-held for detection, when it enters some high-voltage environments, there are many potential safety hazards in such a direct contact method, and for some higher-position cables Leakage detection of lines often requires...

Problems solved by technology

[0003] However, when the existing leakage detector detects the leakage of the cable line, because it needs to be held by hand for detection, when entering some high-voltage environments, such a direct contact method has many potential safety hazards, and for some higher-position cables Leakage detection of lines often requires the use of tools such as ladders, which is inconvenient to use. In summary, the existing leakage detectors are less safe and less practical
