Single-phase and four-meter-position electric energy metering box

Abstract

The invention relates to a single-phase and four-meter-position electric energy metering box. The single-phase and four-meter-position electric energy metering box comprises a box body, a box cover, four electric protection assemblies, collectors and four electric energy meters. Each electric protection assembly comprises a breaker in front of one meter and a breaker behind the meter, wherein the breaker in front of the corresponding meter, the electric energy meter and the breaker behind the meter are sequentially connected to form the electric energy meter assembly. The four electric energy meters are connected with the collectors respectively; the collectors are connected with a remote terminal through a concentrator; the collectors collect electric pulse signals of the four electric energy meters, convert the electric pulse signals into digital data information and transmit the digital data information to the concentrator; the concentrator gathers the data information of all the collectors and transmits the data information to the remote terminal; the electric protection assemblies protect electric equipment against damage. Compared with the prior art, the single-phase and four-meter-position electric energy metering box has the advantages of being intelligent in meter reading, unified in specification to lower the cost, and the like.

Description

technical field [0001] The invention relates to electric equipment, in particular to a single-phase four-meter electrical energy metering box. Background technique [0002] Because the size of the landmarks is different and the latitude is different, the number of households on each floor is different for the commercial houses built by developers considering lighting and construction costs. Therefore, the design of the electric energy box has brought great inconvenience, because some commercial houses The floors are high, and the developer artificially reduces the size of the elevator, so it is becoming more and more unrealistic to send a special person to read the meter. Moreover, because the number of households on each floor is varied, the number of meters in the electric energy box is also varied. Too many specifications inadvertently increase production costs and maintenance costs. [0003] For example, the Chinese patent application number 201210517400.0 discloses a m...

AI Technical Summary

Problems solved by technology

But this electric energy meter metering box has two obvious disadvantages: one is only provided with one meter position, when there are two families in one floor, two metering boxes need to be installed, which increases the cost unintentionally, and also violates the principle The original intention of the invention design; the second is the need for on-site meter reading
