Summary of the invention
The purpose of this invention is to provide a kind of explosion-proof type series capacitor, it has can stop the increasing of sub-prime spalling degree, thereby reduces the characteristics of its harm that causes.
the technical solution adopted in the present invention is: the explosion-proof type series capacitor, the aluminium shell that comprises upper opening, the oral area of this aluminium shell is fixed with the plastics explosion-proof block, the top of this plastics explosion-proof block is provided with crown cap, this crown cap seals the oral area of this aluminium shell, simultaneously, this aluminium enclosure is provided with core parts, these core parts comprise inductance and two sub-primes that are cascaded, and these core parts are provided with leading-out end line, the pin that described leading-out end line comprises the lead-out wire that connects with this core parts and is positioned at this explosion-proof type series capacitor outside, simultaneously, this crown cap is provided with rivet, this plastics explosion-proof block lower surface is provided with the Copper Foil that connects this lead-out wire, and this rivet top connects this pin, the bottom connects this Copper Foil.
Be provided with insulating board between described plastics explosion-proof block and crown cap.
Be provided with the insulating end bowl between described plastics explosion-proof block and crown cap.
Described inductance is enamelled wire, and this enamelled wire is around on inductive rack.
Described core parts outside is provided with the insulation stator cover.
Be provided with inserts between described core parts and aluminium shell.
