The mechanism comprises aprotection base, a coil base is fixedly connected to the interior of the protection base, a voltage regulating base is fixedly connected to the outer surface of the protection base, a mounting base is fixedly connected to the outer surface of the voltage regulating base, a limiting groove is formed in the voltage adjusting base, a compression rod is movably connected into the mounting base, a guide rail is movably connected to the side surface of the compression rod, a limiting plate is fixedly connected to the side surface of the compression rod, a telescopic rod is movably connected to theside surface of the limiting plate, a limiting frame is fixedly connected to the side surface of the telescopic rod, and the side surface of the telescopic rod is movably connected with a telescopic spring. When the mechanism is used, a contact base is connected with other conductive bases, and then the corresponding coil base is conducted, so that the purpose of voltage regulation is achieved, the mechanism is convenient to use, the cost of the mechanism is reduced to a certain extent, and the safety is high.

Description

technical field [0001] The invention belongs to the technical field of three-phase autotransformers, in particular to a three-phase autotransformer safety voltage regulating mechanism. Background technique [0002] Three-phase autotransformer is a special transformer whose output and input share a set of coils. The step-up and step-down are implemented with different taps. The tap voltage of the parts less than the shared coil will be lowered, and the tap voltage of the part more than the shared coil will be raised. high. In fact, the principle is the same as that of ordinary transformers, except that its primary coil is its secondary coil. In general transformers, the left primary coil generates voltage through electromagnetic induction to make the right secondary coil generate voltage. The autotransformer affects itself.

AI Technical Summary

Problems solved by technology

[0003] When adjusting the voltage of a three-phase autotransformer, it is generally adjusted by the staff themselves, which is troublesome to use, with a large workload and low safety. It is not only costly, but also relatively cumbersome. Therefore, in view of this, we will study and improve the existing structure and defects, and provide a three-phase autotransformer safety voltage regulation mechanism, in order to achieve a more practical value.
