Electricity larceny prevention ammeter box

Abstract

The invention discloses an electricity larceny prevention ammeter box. The electricity larceny prevention ammeter box comprises a square-shaped main body which comprises a casing and an upper cover, wherein the upper cover can open and close the enclosed casing through a cipher lock. The cipher lock comprises a lock body; a controller which is arranged in a cavity and comprises a first control unit, a first unit and a second unit, wherein the first control unit is connected with an external power source and a battery, the first control unit is connected with the first unit and the second unit, the first unit is connected with the external power source, and the second unit is connected with the battery; a first alarm which is connected with the first control unit; a motor which is connected with the first unit; an emergency motor which is connected with the second unit; a lock bolt which is driven by the motor or the emergency motor; a lock catch; and a keyboard. The electricity larceny prevention ammeter box provided by the invention is quite high in safety, prevents ammeter damage or electricity larceny caused when non-workers open the ammeter box, and enables the electricity larceny prevention ammeter box to have wider applicability through arrangement of two power supply modes of the external power source and the battery.

Description

technical field [0001] The invention relates to the field of electric power technology. More specifically, the present invention relates to an anti-theft electric meter box. Background technique [0002] Electric meter, the abbreviation of electric energy meter, is an instrument used to measure electric energy, also known as electric meter, fire meter, electric energy meter, kilowatt-hour meter, and refers to an instrument for measuring various electrical quantities. The traditional meter is one meter per household, and the meter is placed in a moisture-proof meter box. The moisture-proof meter box is mainly used to protect the meter for measuring power consumption and isolate the meter from the external environment. Municipal, residential, telecommunications, electric power, rural power grids, factories, enterprises, institutions, heating, fire protection and other places with public facilities need to install ammeters, which also require ammeter boxes. [0003] Most of t...

Problems solved by technology

[0003] Most of the existing electric meter boxes are box-type structures composed of a box body and a box cover. The door of the box is locked by a mechanical lock, which is easy to be opened by human damage.

The meter is installed inside the box, and the meter can be accessed by opening the box door. In some areas where the supervision of the meter box is not in place, this kind of meter box is often opened by residents privately, connecting the lines, and stealing electricity. When reading the meter at the end of the month , removed the lapped lines, and restored the measurement of the electric energy meter, all of which caused serious economic losses to the power sector

At the same time, changes in temperature will affect the measurement error of the electric energy meter, especially in summer, when the temperature in the closed electric meter box is too high, causing changes in current and voltage, resulting in errors, and finally inaccurate measurement results. Therefore, it is urgent to find a An anti-theft electric meter box with high security and can reduce the measurement error of the electric energy meter in the electric meter box
