Problems solved by technology

[0003] This kind of three-color lamp can only be used when the number of voltage-resistant devices of the smart energy meter is small. When multiple devices are subjected to a voltage-resistant test together, it is difficult for the operator to observe and it is easy to cause misoperation.

Abstract

The present invention discloses an intelligent electric energy meter withstand voltage warning device and method. The device comprises a signal control panel, the signal control panel receives the withstand voltage state of an intelligent electric energy meter and sends pulse signals and direction signals to a stepping motor according to the withstand voltage state to control the motion of the stepping motor, and the motion of the stepping motor drives the motion of a warning rod. In the device withstand voltage process, the intelligent electric energy meter withstand voltage attention device does not need manual intervention control, and perform real-time protection once the withstand voltage device starts to work to visually display the work state of the withstand voltage device and avoid operators' maloperation so as to reach the protection and warning effects in the withstand voltage process.

Description

technical field [0001] The invention relates to the technical field of smart electric meter detection, in particular to a smart electric energy meter withstand voltage warning device and a warning method. Background technique [0002] With the increasing requirements of the State Grid Corporation of China for electric energy meters, it is necessary to conduct AC withstand voltage tests on smart electric energy meters. During the AC withstand voltage test, the equipment outputs high voltages up to 4KV, which poses certain safety risks to operators. At present, in the verification device of the withstand voltage test of the smart electric energy meter, the safety protection measures generally used are three-color withstand voltage lamps, which are generally embedded on the columns or beams of the withstand voltage equipment of the electric energy meter, and are controlled by pulses. When it is on, it means that the device has entered an alarm state or has illegal operations; g...
