Problems solved by technology
The electric carbon brush is in contact with the surface of the polished coil. During the voltage regulation process, the brush will short-circuit the two turns of the coil. Due to the large resistance of the electric carbon, the electric carbon itself will generate a high temperature rise when the current passes through it. , the voltage regulating coil is often burned out during use
In addition, the manufacturing power is also limited due to the large resistance of electric carbon

Description
technical field [0001] The invention relates to a voltage regulator, in particular to a screw type contact voltage regulator. Background technique [0002] The column type contact voltage regulator and voltage stabilizer are composed of column type silicon steel sheet iron core, enameled wire and voltage regulating carbon brush. The electric carbon brush is in contact with the surface of the polished coil. During the voltage regulation process, the brush will short-circuit the two turns of the coil. Due to the large resistance of the electric carbon, the electric carbon itself will generate a high temperature rise when the current passes through it. , The voltage regulating coil is often burned out during use. In addition, the manufacturing power is also limited due to the large resistance of electric carbon. These are the disadvantages of the current column contact voltage regulator and voltage stabilizer. Contents of the invention [0003] The technical problem to be ...
