Abstract

The invention belongs to the field of electric power metering, particularly relates to a safety type electric power metering device with a heat dissipation function, and provides the following schemefor solving the problems that a heat dissipation device of an existing electric power metering device generally works continuously, a body of the existing electric power metering device is heated dueto long-time continuous work, the existing electric power metering device is damaged, and the use requirement cannot be met. The device comprises a device body, wherein a cavity is formed in the device body, a rotating motor is arranged at the top end of the inner wall of the cavity, the rotating motor is connected with a rotating shaft through an output shaft, the rotating shaft is fixedly sleeved with blades, and a fixing base is arranged on one side of the inner wall of the cavity. According to the invention, the movable disc can continuously and automatically drive the rotating shaft and the conductive block to rotate, so that power can be intermittently supplied to the rotating motor, self heat dissipation can be effectively guaranteed, the working efficiency is guaranteed, and the use requirements are met.

Description

technical field [0001] The invention relates to the technical field of power metering, in particular to a safe power metering device with heat dissipation function. Background technique [0002] Electric energy metering device is a measuring instrument used to measure and record power generation, power supply (mutual supply), plant power consumption, line loss power and user power consumption. Electric energy metering device refers to an electric energy meter (active and reactive energy meter, maximum demand meter, multi-rate electric energy meter, etc.), metering transformers (including voltage transformers and current transformers) and secondary connecting wires. overall. [0003] The cooling devices of existing power metering devices generally work continuously, and continuous work for a long time will cause the body to heat up, thereby causing self-damage and failing to meet the needs of use. Contents of the invention [0004] The purpose of the present invention is ...
