Power data recorder capable of latching in power-off state

Abstract

The invention provides an electric power data recorder capable of latching in power failure, relates to the technical field of electric power electronic instruments, and aims to solve the problem that when an existing electric power data recorder is used, a wire is long and is easy to wind in use, the electric power data recorder comprises a body, inclined heat dissipation holes are formed in the two sides of the body, and the heat dissipation holes are communicated with the heat dissipation holes. A display mechanism is mounted on the front side of the body; a panel in the display mechanism is installed on the side face of the carrier plate, and supporting plates in the display mechanism are installed on the two sides of the panel; an inner groove in the heat dissipation piece is formed in the side wall of the body, a clamping groove in the heat dissipation piece is formed in the rear side of the panel, and the heat dissipation piece is installed on the side face of the body; and the collecting structure is installed in the body, and a guide wheel in the collecting structure is installed on the inner side wall of the vertical groove through a rotating shaft. The rotating plate is rotated, so that a detection wire on the electric power data recorder is wound on the rotating rod, and the wire is pulled outwards according to the use requirement for the use length.

Description

technical field [0001] The invention belongs to the technical field of power electronic instruments, in particular to a power data recorder capable of power-off latching. Background technique [0002] The power data recorder is an instrument used to measure power quality, power, voltage, current, harmonics and flicker and display real-time data and save them. According to the data saved by the recorder, it can be found during power transmission and use. Seek solutions to problems and make timely recommendations. [0003] For example, the application number: CN201410474201.5 relates to a three-phase power equipment data recorder and analyzer based on an embedded system. The invention has the advantages of a large number of connectable devices, fast speed, multiple functions and strong expandability, and can complete centralized monitoring of a large number of electric devices. Among them, the data record analyzer system as a whole includes: computer management system, data ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a power data recorder that can be powered off and latched to solve the problem that the existing power data recorder has a long wire length and is prone to entanglement when used. It is cumbersome to sort out, and when the power data recorder is not working, the dust in the air easily enters the recorder through the ventilation and cooling holes, and the adhesion of dust affects the heat dissipation effect of the recorder and affects the normal operation of the recorder
