Durable special wiring bottom plate capable of replacing electric energy meter without power failure, and electric energy meter

Abstract

The invention provides a durable special wiring bottom plate capable of replacing an electric energy meter without power failure, and the electric energy meter. The bottom plate is arranged in an electric energy metering box, and comprises a main body lining plate, a connector fixing terminal, a transition fit connector, an insulating protective cover plate and an electricity larceny prevention cover plate, a plurality of first through holes which are opposite to each other are formed in one end of the electricity larceny prevention cover plate; the insulation protection cover plate is provided with a second through hole right opposite to the first through hole, a rotating rod is arranged in the first through hole and the second through hole in a penetrating mode, the electricity larceny prevention cover plate can rotate around the rotating rod, the other end of the electricity larceny prevention cover plate is provided with a plurality of inserting rods, and the inserting rods are perpendicular to the end face of the electricity larceny prevention cover plate and are parallel; and the insulating protective cover plate is provided with slots matched with the inserting rods, the inserting rods are inserted into the slots, and the slots are provided with lock catch pieces, so that on one hand, an electricity larceny prevention function is realized; and the connector assembly fixing terminal is sealed on the main body lining plate, and on the other hand, the opening and closing of the electricity larceny prevention cover plate can be conveniently controlled by opening and closing the lock catch piece, so the electric energy meter can be conveniently maintained, disassembled and assembled.

Description

technical field [0001] The invention relates to the field of electric energy meters, in particular to a durable special wiring base plate and an electric energy meter that can replace the electric energy meter without interruption. Background technique [0002] Electric energy meter is an instrument used to measure electric energy, also known as watt-hour meter, fire meter, kilowatt-hour meter, refers to the instrument for measuring various electrical quantities, commonly known as watt-hour meter, fire meter. [0003] High-quality service is the lifeline of the State Grid, and power supply reliability is one of the most important indicators. Therefore, the requirements for reliability of units at all levels of the company are also increasing year by year. Within hours, the average number of power outages per household is less than 1 time per year. [0004] With the rapid development of society and economy, the total amount of electric energy meters in the power supply area ...

AI Technical Summary

Problems solved by technology

Taking a local power supply company as an example in 2018, there were 38,422 electric energy meters that were rotated every six years, and 3,067 electric energy meters had to be replaced due to failures. In addition, 9,869 electric energy meters were newly installed. 51358 pieces, a huge number of watch replacements

At the same time, the current general-purpose low-voltage meter replacement technology cannot achieve continuous power supply for the time being, which will lead to direct economic losses caused by power outages, as well as indirect economic losses including labor costs for meter replacement, and burnout of user electrical equipment due to power outages. Increased user complaints and reduced user satisfaction. Therefore, there is an urgent need for an electric energy meter structure that can be replaced without power failure, and at the same time can well realize the electric energy meter structure that prevents electricity theft.
