Abstract

In order to solve the problem of poor contact and short-circuit failure during the verification process of the verification smart meter, the present invention provides a verification device for an electric energy meter, including a platform on which: a multimeter and a verification indicator light are arranged , emergency stop button, table body current wiring interface, electric energy meter current wiring interface, meter position data display unit, and multiple electric energy meter positions for accommodating electric energy meters to be verified and multiple hanging meter holders for electric energy meters to be verified , wherein the plurality of epitopes are connected in series. The device can quickly find out where the fault occurs in the current loop, and at the same time, has strong compatibility, and is suitable for the rapid verification of electric energy meters with different numbers of single-phase to three-phase phases.

Description

technical field [0001] The invention relates to the technical field of electric energy meter verification, in particular to an electric energy meter verification device, which is used for quickly detecting the short circuit of the meter of the electric energy meter verification device. Background technique [0002] The electric energy meter is an instrument specially used to measure the accumulated value of electric energy in a certain period of time. [0003] The principle of the electric energy meter verification device to verify the electric energy meter is to use the standard meter method such as figure 1 shown. When verifying the electric energy meter, the electric energy meter is hooked to the meter position of the verification device for the first inspection, the current circuit of the electric energy meter to be tested is connected in series, and the voltage circuit is connected in parallel, and the reference voltage and reference current output generated by the ver...
