Electric power meter with convenient assembly and disassembly and clear observation

Abstract

The invention relates to an electric power meter with convenient assembly and disassembly and clear observation, which comprises a display plate, a meter shell, a protection cover and four mounting mechanisms, wherein the protection cover is internally provided with a cleaning mechanism; the meter shell is provided with a display screen and a plurality of keys; the mounting mechanism comprises a fixing plate, a connection rod and two mounting assemblies; the mounting assembly comprises a fixing pipe, an insertion rod, an insertion ring and a fixing unit; the fixing pipe is internally providedwith a pressing plate and a first spring; the cleaning mechanism comprises a lifting plate, a translation assembly, a translation plate, a cleaning assembly and two lifting assemblies; the cleaning assembly comprises a cleaning block, a second spring and two directional units; and the directional unit comprises a directional rod and a directional pipe. According to the electric power meter with convenient assembly and disassembly and clear observation, the display plate and the meter shell can be connected conveniently through the mounting mechanisms, assembly and disassembly of the meter canbe more convenient and quicker, and besides, a protection frame is cleaned by the cleaning mechanism in wet weather, and the user can thus clearly observe the contents on the display screen, thus improving the practicability of the device.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to an electrical instrument with clear observation which is convenient for loading and unloading. Background technique [0002] Power meters are power measurement and control equipment that provide solutions for power parameter measurement, power quality monitoring and analysis, and electrical equipment control. As an advanced intelligent and digital grid front-end acquisition component, power meters have been widely used in various control systems. System, SCADA system, energy management system, substation automation, community power monitoring, industrial automation, intelligent part-time job, intelligent power distribution cabinet, switch cabinet and other equipment, it has the characteristics of convenient installation, simple wiring, and small engineering quantity. [0003] A power meter usually consists of a watch case and a display panel. In order to achieve a fixed connec...

AI Technical Summary

Problems solved by technology

[0003] A power meter usually consists of a watch case and a display panel. In order to achieve a fixed connection between the watch case and the display board, people usually use four screws to fix the display board. The meter is disassembled by turning the screws, but the disassembly of the meter requires a screwdriver. and other tools, and after long-term use of the screws, it is prone to slipping and rusting, which affects the loading and unloading of the instrument. Not only that, in order to protect the display screen on the instrument, people usually use a protective cover to isolate the display screen from the outside, but when When encountering wet weather such as rainy days, water mist is easy to form on the protective cover, making it impossible for people to see the content on the display screen, which affects the use of power meters and reduces the practicability of existing power meters
