The invention discloses an arc suppression overvoltage protection device, and belongs to the field of on-off arc suppression overvoltage protection. A fast on-off arc suppression overvoltage protection device includes a protection body. An upper support plate is fixedly connected to the bottom side of the protection body. The upper support plate is connected to a lower support plate through a buffer spring. A space between the upper support plate and the lower support plate is filled with thermoplastic buffer rubber. The thermoplastic buffer rubber can be heated to be softened in order to improves the shock absorption and buffering effect of the fast on-off arc suppression overvoltage protection device, achieve effective shock absorption, and prevent excessive vibration. In addition, a hole-type semiconductor and an electron-type semiconductor are disposed at one end in a cooling and dust removal ventilation box to absorb heat, thereby effectively lowering the temperature of the cooling water. Cold air is delivered into the protection body through an air blower to decrease the temperature, thereby effectively achieving shock absorption and prolonging the service life, effectively preventing the accumulation of dust and excessively high temperature, and effectively improving work efficiency.
Description
technical field [0001] The invention relates to the field of switch type arc suppression overvoltage protection, and more specifically relates to a fast switch type arc suppression overvoltage protection device.
