Make various circuits or electrical equipment work normally under the rated working voltage. The contact voltage regulator is a compensated AC voltage regulator, which adjusts the output voltage by adjusting the different positions of the brushes.

The contact voltage regulator will generate a lot of heat during the working process. In order to stabilize its working state, the heat must be disposed of. The traditional heat dissipation method is to attach cooling fins on the side wall of the main body of the contact voltage regulator. A large number of cooling fins are formed on these cooling fins. The heat generated by the contact voltage regulator depends on these cooling fins to transfer heat to the air. walk away. Some contact voltage regulators have a large power consumption and generate a lot of heat, so the manufacturer has equipped a special cooling fan, which blows air against the heat sink. However, in actual use, the above heat dissipation methods are not ideal. During the blowing and heat dissipation process of the fan, due to the obstruction of other components or the problem of the installation position of the fan, there are many dead angles that cannot be blown by the wind, and the heat dissipation efficiency is very low. In order to solve this problem, some manufacturers equip high-power fans for heat dissipation, which in turn leads to a large loss of electric energy and is not environmentally friendly.
