The invention discloses an electric energy meter calibrating device with an electric shock prevention function, and the device comprises: a calibrating platform which comprises an installation platform, wherein a plurality of to-be-detected electric energy meters are fixedly installed on the installation platform, and a calibrating circuit is arranged on the periphery of each calibrating electric energy meter; a plurality of to-be-detected areas which are uniformly distributed on the detection platform at the installation positions of the to-be-detected electric energy meters and the detection circuit; and an insulating cover which selectively covers the periphery of the to-be-detected area, wherein the insulating cover and the to-be-detected electric energy meters are arranged at an interval. According to the electric energy meter calibrating device, before the to-be-detected electric energy meters is detected, the insulating cover is covered on the to-be-detected area of the to-be-detected electric energy meters and the calibrating circuit, and then the to-be-detected electric energy meters are electrified, so that an operator is prevented from accidentally touching a conductive element in the to-be-detected area, and the safety of the detector is ensured; and the safety coefficient of the verification work of the electric energy meter is improved.
Description
technical field [0001] The invention relates to the technical field of electric equipment maintenance, in particular to an electric energy meter verification device with an electric shock prevention function. 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 the watt-hour meter is connected to the circuit under test, alternating current flows through the current coil and the voltage coil, and these two alternating currents generate alternating magnetic flux in their iron cores respectively; the alternating magnetic flux wears Passing through the aluminum disc, an eddy current is induced in the aluminum disc; the eddy current is subjected to force in the magnetic field, so that the aluminum disc obtains torque (active torque) and rotates. [0003] In order to monitor the a...
