Contact resistance reduction device for contact

The present disclosure relates to a contact resistance reduction device for a contact, the contact comprising a first contact and a second contact, the contact resistance reduction device comprising a controller and a boost module. The boosting module is electrically connected with the controller, the boosting module is provided with a first positive terminal and a first negative terminal, the first positive terminal and the first negative terminal are used for being connected with the first contact and the second contact respectively, and the boosting module can increase voltage to enable the first contact and the second contact to generate electric arcs in a contact state. The boosting module can generate a high voltage, so that a high-voltage arc is generated between the first contact and the second contact, and an oxidation film on the surface of the contact is burnt by utilizing high temperature generated when the high-voltage arc is generated, so that the oxidation film on the surface of the contact is
