Description
Technical field
This utility model belongs to power capacitor field, is specifically related to a kind of power capacitor Explosion-proof cap assembly.
Background technology
Power capacitor, for the capacitor of power system and electrical equipment, is applied to multiple industries such as electronics, household electrical appliances, communication, electric power, electric railway, hybrid vehicle, wind-power electricity generation, solar electrical energy generation；Owing to power capacitor application is more and more extensive, the quality requirements of capacitor is increasingly stricter, and the equipment of capacitor manufacturing is increasingly advanced, and manufacturing process, design concept are all in continuous lifting.Capacitor itself is container, and maximum hidden danger of quality is to turn pale, explode, after power capacitor puts into operation, producing very big heat, inside creates a large amount of gas and cannot get rid of, and capacitor works on, produce heat and more gas, finally result in blast.Therefore, it is an important task to the explosion-proof of power capacitor.
Utility model content
Many the solving the technical problem that of this utility model is: the problem exploded for power capacitor and turn pale, it is provided that a kind of power capacitor Explosion-proof cap assembly.
Technical solution adopted in the utility model is:
A kind of power capacitor Explosion-proof cap assembly, including bursting diaphragm, aluminium lid, electrode tip holder, bolt, silica bead, epoxy plate, nut, copper foil, aluminium rivet；Outside aluminium lid lid recessed, lid inner face is protruding, and outer capping is connected by bolt with electrode tip holder, bolt-through electrode tip holder and aluminium lid, utilizes silica bead, epoxy plate to be enclosed within bolt at aluminium lid lid inner face place, with nut screwing clamping, makes electrode tip holder be combined with aluminium lid.Bursting diaphragm arranges the hole corresponding with bolt, and copper foil is fixed on bursting diaphragm by hole end aluminium rivet；Aluminium lid and bursting diaphragm being bolted, bolt end just contacts with copper foil, utilizes spot welding to fix the two.
Further, described electrode tip holder center arranges oil filler point bolt.
Further, described bolt arranges bolt extended surface.
Further, the bolt quantity of described Explosion-proof cap is determined according to the number of phases of capacitor.
The beneficial effects of the utility model are: provide a kind of power capacitor Explosion-proof cap assembly, heat is produced when capacitor runs, when forming hot gas, internal pressure raises, by weaker for capacitor stress and containing male and fomale(M&F) aluminium lid protuberance deformation, the solder joint that Copper Foil on bursting diaphragm is connected with screw rod is subject to a pulling force upwards, along with pulling force is gradually increased, screw rod and Copper Foil come off, capacitor core body disconnects with binding post (screw rod), form open circuit, capacitor quits work, heat will not produced, just no longer produce hot gas, thus preventing the blast of power capacitor.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
A kind of Monophase electric power capacitor from explosion cap assembly as shown in Figure 1, Figure 2, Figure 3 shows, including bursting diaphragm 1, aluminium lid 2, electrode tip holder 3, bolt 4, silica bead 5, epoxy plate 6, nut 7, copper foil 8, aluminium rivet 9；Aluminium lid 2 lid outside is recessed, and lid inner face is protruding, and outer capping is connected by bolt 4 with electrode tip holder 3, bolt 4 penetrating electrode seat 3 and aluminium lid 2, utilizes silica bead 5, epoxy plate 6 to be enclosed within bolt 4 at aluminium lid 2 lid inner face place, tightens with nut 7, makes electrode tip holder 3 be combined with aluminium lid 2.Bursting diaphragm 1 arranges the hole corresponding with bolt 4, and copper foil 8 is fixed on bursting diaphragm by hole end aluminium rivet 9；Aluminium lid 2 and bursting diaphragm 1 being connected by bolt 4, bolt 4 end just contacts with copper foil 8, utilizes spot welding to fix the two.The male and fomale(M&F) of aluminium lid 2, the buffering of deformation when being conducive to it to be subject to capacitor internal pressure；Utilize silica bead 5 can block electrode and aluminium lid 2, it is prevented that the electric leakage of capacitor and sealing；Described biphase power capacitor Explosion-proof cap assembly fills on the capacitor; when capacitor internal produces a large amount of gas because of heating, chemical reaction etc.; gas makes aluminium lid deform protuberance; then the spot welding contact of bolt 4 and copper foil 8 place is broken; make circuit occur to form open circuit, make capacitor core body power-off, no longer work; do not produce gas, thus protecting power capacitor not have the danger of blast.
As required, as it is shown in figure 1, oil filler point bolt 10 can be arranged in the center of Explosion-proof cap, after Explosion-proof cap assembly and aluminium shell of capacitor are sewed up by crimping, again through oiling machine evacuation to power capacitor oiling.
Bolt 4 as shown in Figure 1, arranging bolt extended surface 11 with electrode tip holder 3 upper surface level place, when electrode tip holder 3 wiring, it is possible to increases the contact surface with line, is substantially reduced the generation of heat.
As shown in Figure 4, the design of described power capacitor Explosion-proof cap assembly has single-phase, three-phase, four phases.
Of the present utility model ultimate principle, principal character and of the present utility model advantage have more than been shown and described.This utility model is not restricted to the described embodiments; described in above-described embodiment and description is that principle of the present utility model is described; under the premise without departing from this utility model spirit and scope, this utility model also has various changes and modifications, and these changes and improvements both fall within claimed scope of the present utility model.This utility model claims scope and is defined by appending claims and equivalent thereof.
