Calibration device for automatically advancing and retreating electric energy meter

Abstract

The invention discloses a calibration device for automatically advancing and retreating an electric energy meter, the calibration device is used for calibrating a to-be-calibrated electric energy meter, the calibration device comprises a cabinet body, a controller, an error processing system, a current and voltage generating device and a standard electric energy meter are arranged in the cabinet body, a control panel is installed on the surface of the cabinet body, the control panel is connected with the controller, and the controller is connected with the error processing system. The cabinet body is provided with an electricity meter bin, the electricity meter bin is provided with a drawer, the drawer comprises a panel and a bottom plate, the panel is perpendicular to the bottom plate, the panel is used for shielding an opening of the electricity meter bin, a ball screw is arranged between the bottom plate and the inner wall of the electricity meter bin, and the cabinet body is provided with an observation window. An observation window is arranged on the cabinet body, a transparent cover is installed at the observation window, the observation window is located above the electric meter bin, a cabinet door is arranged on the cabinet body, and the calibration device can enable calibration of the electric energy meter to be simpler and more convenient.

Description

【Technical field】 [0001] The invention relates to a calibration device for an electric energy meter that automatically advances and retreats, and belongs to the technical field of calibration devices for electric energy meters. 【Background technique】 [0002] At present, the inspection of electric energy meters is all concentrated in the power metering centers of the provincial companies, and the county power supply companies do not have electric energy meter inspection devices; In the metering center of the prefectural and municipal bureaus, when users have doubts about the accuracy of the energy meter, there will be multiple round-trip verifications, which will greatly increase the workload of front-line employees, and the service cycle is long, but sometimes it still cannot allow users Satisfied; in order to improve the service timeliness of electric energy meter complaints from users in various places and quickly solve users' questions, it is recommended to set up a set ...

[0002] At present, the inspection of electric energy meters is all concentrated in the power metering centers of the provincial companies, and the county power supply companies do not have electric energy meter inspection devices; In the metering center of the prefectural and municipal bureaus, when users have doubts about the accuracy of the energy meter, there will be multiple round-trip verifications, which will greatly increase the workload of front-line employees, and the service cycle is long, but sometimes it still cannot allow users Satisfied; in order to improve the service timeliness of electric energy meter complaints from users in various places and quickly solve users' questions, it is recommended to set up a set of application and inspection system for electric energy meters in the service window (business hall) of the power supply station, which can solve users in the first time at the business outlets complaints

However, the existing professional electric energy meter calibration platform is high in purchase cost, bulky and complex in construction, which is only suitable for professionals and not suitable for the business hall of power supply stations.
