Portable electricity stealing and leakage checking measuring instrument

Abstract

The invention discloses a portable electricity stealing and leakage checking measuring instrument, belongs to an electric power measurement facility. The measuring instrument comprises a box body anda sliding block, a storage battery is mounted in the box body; a current collector is fixed at the top of the box body close to the storage battery; the storage battery and the current collector are isolated through a partition plate, a handle is fixed to one side of the exterior of the box body, mounting grooves are formed in the four corners of the side, close to the current collector, of the box body, mounting blocks are fixed to the side, close to the mounting grooves, of the current collector, and fixing grooves are formed in the sides, away from the current collector, of the mounting blocks. The utility model discloses a portable electricity stealing and leakage checking measuring instrument. The mutual inductor is connected with the current collector; the current of the input end isdetected through the mutual inductor, the current of the output end is detected through the mutual inductor by the other current collector, and through comparison between the current of the input endand the current of the output end, when the sum of the currents of the output end is smaller than the current of the input end, the circuit has the phenomena of electric leakage or electricity stealing and the like, and the circuit is convenient to detect.

Description

technical field [0001] The invention relates to the technical field of circuit detection, in particular to a portable electric leakage measuring instrument. Background technique [0002] At present, the 0.4kV line is mainly routed along the perimeter of the house. When the line passes through the shop, the line is surrounded by billboards, so that the inspectors cannot understand the situation of the line inside the billboard. There is a risk of leakage and stealing of electricity in the line inside the billboard. In order to avoid leakage and stealing of electricity, the circuit needs to be checked detection. [0003] When the existing circuit detection device detects electric leakage and electricity theft, it needs to check the condition of the circuit inside the billboard, and the billboard needs to be removed, causing damage and waste, and there is also the risk of being complained by users, which is inconvenient to use. Use brings certain inconvenience. Contents of ...
