The invention relates to a new type of explosion-proof film capacitor, which belongs to the field of capacitors. The connection mode of "serial first and then parallel" is adopted between winding cores to reduce the influence of winding core breakdown on capacitors; It is not easy to damage the adjacent winding core or insulate the shell; use heat-conducting epoxy resin, heat-conducting oil, and arc-shaped concave surface to improve the heat exchange effect, which is beneficial to prevent the expansion of the fault or the explosion of the shell; The circuit is burned or exploded due to the breakdown caused by the excessive current, so as to ensure the continuous stability of the current and voltage in the bypass components; the overvoltage protection device protects the electrical components from the impact of overvoltage and high voltage. The capacitor has a compact structure, saves installation space, reduces operating failure rate, lower overall loss, and lower cost, which is conducive to reducing manufacturing quality defects; the capacity of electrical components is large, the number of winding cores is small, the production efficiency is high, and the explosion-proof performance is good.
