Adjustable security and anti-theft transformer

Abstract

The invention discloses an adjustable safety and anti-theft transformer, which comprises a casing, the top of the casing is provided with a top cover, the left and right side walls of the inner cavity of the casing are provided with slide grooves, the outer walls of two sets of slide grooves are provided with sliders, and the sliders Matching with the chute, a connecting rod is arranged between the two groups of sliders, a screw hole is arranged on the outer wall of the top cover, an adjusting bolt is arranged on the top of the top cover, the bottom of the adjusting bolt penetrates the bottom of the screw hole, and the top of the connecting rod There is a positioning screw groove, and the adjusting bolt is connected with the connecting rod through the positioning screw groove. The adjustable safety and anti-theft transformer of the present invention can realize the compression and stretching of the coil by rotating the knob, change the inductance parameter in the intermediate frequency transformer, and change the inductance of the coil. Quantity, so as to realize the precise adjustment of the inductance of the transformer, and the safety protection performance is good, which can effectively prevent theft. In addition, it is convenient for wiring, has a certain shock absorption and anti-seismic ability, and has good stability.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to an adjustable safety and anti-theft transformer. Background technique [0002] With the gradual increase of the power transmission and transformation voltage of the power grid, the application of large-capacity outdoor transformers with a voltage level of 3KV and above is becoming more and more common. Large-capacity main transformers of 35 kV and above are generally placed outdoors, and need to have certain protection and anti-theft safety performance. General transformers do not have the function of shock absorption, and the normal operation of the transformer will be affected by vibration. The existing adjustable intermediate frequency transformer is mainly composed of a metal shell, a magnetic core, an inductance coil and an adjustable magnetic cap. The inductance parameter can be adjusted by rotating the angle of the adjustable magnetic cap. The intermediate frequency t...

Problems solved by technology

Large-capacity main transformers of 35 kV and above are generally placed outdoors, and need to have certain protection and anti-theft safety performance. General transformers do not have the function of shock absorption, and the normal operation of the transformer will be affected by vibration.

The existing adjustable intermediate frequency transformer is mainly composed of a metal shell, a magnetic core, an inductance coil and an adjustable magnetic cap. The inductance parameter can be adjusted by rotating the angle of the adjustable magnetic cap. The intermediate frequency transformer with this structure is not easy to adjust. Inconvenient to use
