Embodiment Construction

[0033] The present invention will be described in the form of embodiments below in conjunction with the accompanying drawings, so as to assist those skilled in the art to understand and realize the present invention. Unless otherwise stated, the following embodiments and technical terms therein should not be understood without departing from the background of technical knowledge in this technical field.

[0034] The invention provides an electric meter box to solve the technical problem that the interference effect of the anti-knock smart electric meter formed by using a bluetooth electromagnetic lock is low.

[0035]The technical specifications of the electric energy meter box stipulate that the meter box has an integrated structure, and the base of the box body is required to be an integrally formed overall structure base. Meter box structure Except for the three-phase 2-meter general-purpose meter box, which is a single electric energy meter room, the three-phase low-voltag...

Abstract

An electric meter box belongs to the field of electric meter boxes. It includes a box base and a box door, and an electric energy meter room for installing an electric energy meter is formed in the box body base. The electric energy meter has a constant light-emitting lamp group, and a physical isolation type Observation section; also includes a light sensor, a beam splitter is provided on the box door, and the beam splitter is used to divide the display light beam emitted by the constant-on type light-emitting lamp group of the corresponding electric energy meter into at least two beams, and make one of them It can be irradiated on the light sensor to form a detection beam, and another beam can pass through the physically isolated observation part to form an indicating beam. The light sensor is installed at the corresponding position in the box base, and a There is a light-shielding part, so that the light-shielding part can block the light beam incident from the outside of the box base and the box door to stimulate the false response of the light sensor. It does not produce electromagnetic radiation, and it can avoid the influence of electromagnetic interference.

Description

technical field [0001] The invention relates to the technical field of electric meter boxes, in particular to an electric meter box. Background technique [0002] The electric energy measurement method of my country's power grid is as follows: the load end of the meter is connected to multiple metering sub-meters, and multiple metering sub-meters are connected in parallel; the load end of the metering sub-meter is connected to multiple metering terminals, and multiple metering terminals are connected in parallel; The load end of each metering terminal corresponds to a power user. Considering the line loss, under normal circumstances, the ratio of the measured power consumption of the main meter to the sum of the measured power consumption of all the corresponding metering sub-meters is within a reasonable range, and the measured power consumption of the metering sub-meter and its corresponding The ratio of the sum of the measured electric energy usage of all metering termina...
