And electric energy meter incoming and outgoing lines are reversely connected with quick inspection instrument

Abstract

The invention belongs to the field of quick inspection instruments. The invention relates to an electric energy meter incoming and outgoing line reverse connection quick inspection instrument. In thecase of power connection, reverse connection often occurs due to large workload of power workers. Influence on electricity consumption of residents or enterprises, the problem that the use requirementcannot be met is solved; proposed now is the following scheme, the inspection instrument comprises an inspection instrument body, wherein the inspection instrument body is of a hollow structure; a mounting base is arranged at the bottom end of the inner wall of the inspection instrument body; a rotating motor is arranged on the mounting base; the rotating motor is connected with a driven shaft through an output shaft; a movable through hole is formed in the inspection instrument body; the device is reasonable in structure, drives the indication ball to rotate through the rotating motor, can quickly judge whether the incoming and outgoing lines of the electric energy meter are reversely connected or not according to the rotating direction of the indication ball, and can avoid a condition that the rotating direction of the indication ball cannot be judged because the rotating motor rotates too fast because of convenient use through the movement of the conductive part on the conductive coil.

Description

technical field [0001] The invention relates to the technical field of quick checkers, in particular to a quick checker for reverse connection of incoming and outgoing wires of electric energy meters. Background technique [0002] An electric energy meter is an instrument used to measure electric energy, also known as an electric meter, a fire meter, or a kilowatt-hour meter, and refers to an instrument for measuring various electrical quantities. When using the energy meter, it should be noted that in the case of low voltage (not exceeding 500 volts) and small current (tens of amps), the energy meter can be directly connected to the circuit for measurement. In the case of high voltage or high current, the electric energy meter cannot be directly connected to the line, and needs to be used with a voltage transformer or a current transformer. Most of the electric energy meters currently in use are electronic, and the electronic electric energy meter will not be able to use e...
