Description
Technical field
The utility model relates to capacitor, is specifically related to a kind of two-terminal power electronic capacitor of built-in explosion-protection equipment.
Background technology
At present, on market, cylindrical low voltage parallel capacitor majority adopts screwed joint, cable is connected with electrode for capacitors joint, cable is welded to the head of the bolt in bursting diaphragm by the mode of soldering, the key influence factor of this kind of blast resistance construction is diameter and the welding quality of capacitor body lead-in wire, when carrying out capacitor body and cover plate turns weldering, heat during welding can by capacitor body leading conductive on kind of solder joint, damage kind of solder joint, particularly for the product of big current, because of the capacitor body lead-in wire that it has selected diameter thicker, during welding, heat conduction is larger, even more serious on the welding quality impact at kind of solder joint place, so the kind solder joint of capacitor body lead-in wire becomes the main hidden danger of the quality problems of noinductive capacitor.When capacitor failure, be not easy fast capacitor to be disconnected from the circuit, easily cause the danger such as short circuit, blast.
Utility model content
Technical problem to be solved in the utility model realizes a kind of advantages of simple, the two-terminal power electronic capacitor of the built-in explosion-protection equipment that reliability is higher.
To achieve these goals, the technical solution adopted in the utility model is: a kind of noinductive capacitor, be fixed in capacitor case by the molecular core group of some cores, described shell one end is provided with cover plate, be fixed with end seat outside described cover plate, described end seat is provided with binding post, is provided with bursting diaphragm inside described cover plate, be provided with metal weld tabs inside described bursting diaphragm, described binding post electrode is through the wire bonds of end seat, cover plate, bursting diaphragm and metal weld tabs and core group.
Described cover plate is aluminium panels, and cover plate upper punch is pressed with the groove placing end seat.
The electrode of described binding post is copper nickel plating material, and its one end is cylindric, and the other end runs through the end corresponding aperture of seat, cover plate, bursting diaphragm and metal weld tabs and affixed with metal weld tabs.
Described binding post is by rivet and metal weld tabs riveted.
Described end seat is fixing on the cover board by screw bolt and nut, and establishes sealing gasket between end seat and cover plate.
Described bolt end inserts in bursting diaphragm, and bolt-center is set to through hole.
Be filled with heat radiation filler in described shell, and core group is fixed in positioning sleeve in the enclosure, between the fuse of described core group, be provided with grid spacer.
Be provided with dress protective cover outside described end seat, described protective cover is provided with fixed leg, and described cover plate is provided with the built-in hole of matching with fixed leg.
