Problems solved by technology

[0003] When the existing electric metering current transformer is in use, the dust in the external environment may have a certain influence on the current transformer, which hinders the normal use of the current transformer, and is easy to cause certain damage to the internal components. Not good for long-term use

Abstract

The invention discloses a current transformer for electricity larceny prevention metering. A bottom plate is included. Vertical plates are fixedly connected to two sides of a top of the bottom plate.The tops of the vertical plates are fixedly connected with a transverse plate; dust suction devices are fixedly connected to the two sides of the top of the transverse plate; a motor box is fixedly connected to the top of the bottom plate; a motor is fixedly connected to the bottom of an inner wall of the motor box; a rotating rod is fixedly connected to an output shaft of the motor; a first gearis fixedly connected to a surface of the rotating rod, and a second gear is meshed with one side of the first gear. In the invention, the dust suction devices and the transformer device are arranged so that when the current transformer works, interference of dust in the outside on the current transformer is effectively reduced, structural stability of the current transformer is improved, and an influence of external vibration on the normal work of a power supply transformer is prevented to a certain extent; and electricity of the current transformer can be prevented from being stolen in time,and normal transmission of electric energy is ensured.

Description

technical field [0001] The invention relates to the field of current transformers, in particular to a current transformer for anti-electricity theft measurement. Background technique [0002] The principle of the current transformer is based on the principle of electromagnetic induction. The current transformer is composed of a closed iron core and a winding. Its primary side winding has a small number of turns and is connected in the line of the current to be measured. Therefore, it often has all the lines of the line. The current flows, the number of turns of the secondary side winding is relatively large, and it is connected in series in the measuring instrument and the protective circuit. When the current transformer is working, its secondary side circuit is always closed, so the measuring instrument and the protective circuit are connected in series. The impedance is very small, and the working state of the current transformer is close to a short circuit. The current t...
