Abstract

The invention provides a breaking point detection device for an alternating current line. The breaking point detection device comprises a sensing coil, an amplifying circuit, a signal indicator and apower supply. The sensing coil is used for sensing a changing magnetic field of the alternating current line and producing a sensing voltage signal; the input end of the amplifying circuit is connected with the sensing coil and used for receiving the sensing voltage signal; the signal indicator is connected with the output end of the amplifying circuit and used for indicating the sensing voltage signal; the power supply is connected with the amplifying circuit and the signal indicator and used for power supply. The breaking point detection device for the alternating current line can utilize the sensing coil to sense magnetic field change produced by alternating voltage of the alternating current line so as to produce sensing voltage, utilizes the amplifying circuit to amplify the sensing voltage so as to enable the signal indicator to work, and accordingly makes a user to judge whether the alternating current line is short-circuit or not according to the change of an indicating signal.

Description

technical field [0001] The invention relates to the technical field of electrical test equipment, in particular to a breakpoint detection device for AC lines. Background technique [0002] AC power is the necessary energy for the work of various equipment, and the three wires of the AC power supply, the live wire, the neutral wire, and the ground wire, will have breakpoints when they work normally. A long time of use or too much force in the construction stage or quality problems of the wire itself will cause breakpoints after use, and these breakpoints are sometimes definite and sometimes intermittent, no matter what the situation is. point, it is difficult to determine the location of the breakpoint. [0003] Therefore, how to provide a breakpoint detecting device for an AC line that can effectively detect the line break position of the AC line is a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0004] In view of this, ...
