Abstract
The invention discloses an anti-explosion capacitor which comprises an anti-explosion valve. The anti-explosion valve is disposed on the oil filling hole of a capacitor body. The anti-explosion valve comprises an anti-explosion sleeve with a cavity. The anti-explosion sleeve is provided with an inlet communicated with the inside of the capacitor body. A cock is inserted in the anti-explosion sleeve. An anti-explosion aluminum sheet for blocking the inlet is disposed at the lower end of the cock. A brass washer is disposed between the anti-explosion aluminum sheet and the cock. The anti-explosion capacitor has the advantages that the aluminum sheet with relatively low strength is used as the anti-explosion material, and one side of the anti-explosion aluminum sheet is adhered to the brass washer through sealant so as to increase grinding-in degree; due to the fact that the pressure resistance of the anti-explosion aluminum sheet is smaller than that of the stainless steel of a case, during internal pressure increasing, the internal pressure reaches the pressure resistance limit of the anti-explosion aluminum sheet first and breaks the anti-explosion aluminum sheet, the internal pressure is therefore released, and the capacitor can be prevented from exploding due to excessively large pressure; due to the fact that a spring device is omitted, the size of the anti-explosion valve is reduced.
Description
Technical field
The present invention relates to capacitor area.
Background technology
Capacitor is after long-time use, and inside is easy to produce heat energy, causes internal pressure to raise.In the time that pressure is elevated to certain numerical value, be easy to cause the even situation generation of capacitor blast of condenser breakdown.
Existing capacitor mainly adopts increase relief valve to carry out inner pressure release in the time preventing capacitor internal hypertonia, traditional relief valve is as disclosed structure in number of patent application " 201310400664.2 ", this structure is referring to this patent accompanying drawing 1, mainly comprise: explosion-proof plug, seal one, anti-explosion set, described explosion-proof plug and described nested cooperation of anti-explosion set screw thread, described seal one is between described explosion-proof plug and described anti-explosion set, also comprise spring and lower compact heap, described explosion-proof plug axle center place is provided with through hole, in described through hole, top is provided with position limiting structure, in described through hole, below is provided with contraction mouth, described lower compact heap is arranged between described position limiting structure and described contraction mouth, described spring is between described position limiting structure and described lower compact heap.Described anti-explosion set is for being welded on the seal casinghousing of capacitor.
Said structure, because needs arrange spring, is therefore difficult to control explosion-proof valve at longitudinal volume.And due in capacitor internal pressure increase process, spring coverage can reduce, thereby produce finedraw, at this moment the liquid of capacitor internal just can spill from finedraw.
Summary of the invention
For the deficiencies in the prior art, the invention provides noinductive capacitor, in timely releasing capacitor internal pressure, noinductive capacitor of the present invention has less explosion-proof valve installation volume and can not produce the seepage of capacitor internal liquid.
The present invention is achieved through the following technical solutions: noinductive capacitor, comprise capacitor body, on described capacitor body, offer oil filler point, on described oil filler point, explosion-proof valve is set, described explosion-proof valve comprises the anti-explosion set with cavity, and anti-explosion set has the entrance with capacitor body internal communication, in described anti-explosion set, plugs cock, be provided with the explosion-proof aluminium flake of establishing described entrance for stifled in described cock lower end, between described explosion-proof aluminium flake and described cock, brass washer be set.
In technique scheme, described explosion-proof aluminium flake and described brass washer are bonding by sealant.
In technique scheme, described anti-explosion set upper surface arranges groove, and the first sealing ring is set in described groove, and described the first sealing ring is between described cock and described anti-explosion set.
In technique scheme, between described anti-explosion set and described explosion-proof aluminium flake, the second sealing ring is set.
The present invention has following beneficial effect: the present invention utilizes aluminium flake that intensity is relatively little as explosion-proof lamp, the one side of explosion-proof aluminium flake with sealant by brass washer sticky and together with increase break-in degree.Because the voltage endurance capability of explosion-proof aluminium flake is less than the stainless voltage endurance capability of case shell itself, in internal pressure increase process, first internal pressure can reach the withstand voltage limit of explosion-proof aluminium flake, in this case, first explosion-proof aluminium flake is broken, thereby by earth pressure release out, avoid capacitor to blast because pressure is excessive.Owing to having reduced spring assembly, the volume of explosion-proof valve is reduced.
Brief description of the drawings
Fig. 1 is the structural representation of capacitor of the present invention.
Fig. 2 is the structural representation of explosion-proof valve.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail: referring to Fig. 1 to Fig. 2, noinductive capacitor, comprise capacitor body 100, on described capacitor body 100, offer oil filler point 102, on described oil filler point 102, explosion-proof valve 101 is set, described explosion-proof valve 101 comprises the anti-explosion set 7 with cavity, anti-explosion set 7 has the entrance 6 with capacitor body 100 internal communication, in described anti-explosion set 7, plug cock 1, be provided with the explosion-proof aluminium flake 4 of establishing described entrance 6 for stifled in described cock 1 lower end, between described explosion-proof aluminium flake 4 and described cock 1, brass washer 3 is set, described brass washer 3 is bonding by sealant and described explosion-proof aluminium flake 4, for strengthening the edge strength of explosion-proof aluminium flake 4, improve the fastening degree of explosion-proof aluminium flake 4 and cock 1.
Described anti-explosion set 7 upper surfaces arrange groove 70, and the first sealing ring 2 is set in described groove 70, and described the first sealing ring 2 is between described cock 1 and described anti-explosion set 7.Between described anti-explosion set 7 and described explosion-proof aluminium flake 4, the second sealing ring 2 is set.
The present invention utilizes aluminium flake that intensity is relatively little as explosion-proof lamp, the one side of explosion-proof aluminium flake with sealant by brass washer sticky and together with increase break-in degree.Because the voltage endurance capability of explosion-proof aluminium flake is less than the stainless voltage endurance capability of case shell itself, in internal pressure increase process, first internal pressure can reach the withstand voltage limit of explosion-proof aluminium flake, in this case, first explosion-proof aluminium flake is broken, thereby by earth pressure release out, avoid capacitor to blast because pressure is excessive.Owing to having reduced spring assembly, the volume of explosion-proof valve is reduced.And the mounting points using oil filler point as explosion-proof valve, has improved installation convenience.
