Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
As shown in figures 1-4, the high-speed rail locomotive dedicated capacitor, including capacitor protector 10, be located at capacitor protector 10 inside
Capacitor core group 20, capacitor cover 40, the inside of the capacitor protector 10 is filled with, and capacitor core group 20 is completely covered
Insulation stopping 30, the capacitor cover 40 are tightly connected with capacitor protector 10；The capacitor core group 20 is by multiple capacitors
Core is made up of in parallel or mixed connection.The Insulation stopping 30 is one of capacitor wax, epoxy resin, insulating oil.
The outside of the capacitor cover 40 is provided with anti-explosion mechanism 50, and the anti-explosion mechanism 50 includes outer tube 51, positioned at outer
Inner tube 52, counterweight column 53 compatible with 52 inner cavity of inner tube, the capping 54 that 51 upper end of outer tube is set inside pipe 51, by outer tube
The rubber slab 55 of 51 lower ends sealing, the check valve 56 that is arranged in outer tube 51 outside, the center of the capacitor cover 40 be provided with and
The compatible mounting hole in 51 lower end of outer tube, the lateral wall of 51 lower end of outer tube and the hole wall of mounting hole are tightly connected, the rubber
The inside of capacitor protector 10 is arranged in offset plate 55, and more connecting rods 57, the connecting rod are provided between the outer tube 51 and inner tube 52
57 one end is fixedly connected with the inner wall of outer tube 51, and the other end of the connecting rod 57 is fixedly connected with the outer wall of inner tube 52, described
The side wall of connecting rod 57 is close to the upper face of rubber slab 55；The center of 55 upper face of rubber slab is provided with the first blind hole of back taper
552, the center of 55 lower face of rubber slab is provided with the second blind hole of taper 551, the lower end and second of first blind hole 552
Spacing is provided between the upper end of blind hole 551；The lower end of the counterweight column 53 is provided with tapering compatible with the first blind hole 552
531, the side wall of said inner tube 52 is provided with through-hole 521, and the capping 54 and the upper end of outer tube 51 are tightly connected, said inner tube 52
Upper end and capping 54 between be provided with gap, the import of the check valve 56 is connected to the inner cavity of outer tube 51, the outer tube 51
Internal air pressure is 51~65kPa.
Insulation stopping 30 is perfused in the inside of the capacitor protector 10 under normal pressure.By the way that the outlet of check valve 56 is connected
Vacuum pump, vacuum pump vacuumize operation and the air pressure inside outer tube 51 are made to be less than atmospheric pressure.When in capacitor core group 20
Self-healing or breakdown occur for capacitor core to generate gas, this increases the air pressure inside capacitor protector 10, the air pressure of increase
Meeting is so that the central part stress of rubber slab 55 is heaved upwards, while be will push counterweight column 53 and being moved upwards；Due to the second blind hole
551 be taper, and the deformation degree that the center of 55 lower face of rubber slab occurs in this is bigger；53 shell of counterweight column uses lead block
It being made, the density of lead is big, under equal quality, the small volume of lead block；The central part of rubber slab 55 is by capacitor protector
Bulging inside 10 is pushed dynamic so that the tapering 531 of 53 lower end of counterweight column is easier to puncture the central part of rubber slab 55；Work as capacitor
When air pressure inside device shell 10 reaches threshold, the central part of rubber slab 55 is punctured, and the gas inside capacitor protector 10 can push away
Dynamic counterweight column 53 moves upwards and enters the inner cavity of outer tube 51 by through-hole 521；The inner cavity of outer tube 51 and the inner cavity of inner tube 52
In connected state, the gas inside capacitor protector 10 can lead the inner cavity for entering outer tube 51 off, to avoid capacitor protector
10, bulge, explosion occur for inner tube 52.When air pressure recovery inside outer tube 51 situation equal with atmospheric pressure, if outer tube 51
Internal air pressure continues to increase, i.e. air pressure inside outer tube 51 is greater than atmospheric pressure, at this point, the gas inside outer tube 51 can pass through list
Outwardly lead off to valve 56；And the presence of check valve 56, ambient atmos can be stopped to enter the inside of outer tube 51.Therefore, energy
Enough avoid capacitor premature failure.
The presence of rubber slab 55, so that the inside of capacitor protector 10 keeps enough leakproofness, even if because the originals such as aging
Because causing the inside of outer tube 51 to enter water vapour, rubber slab 55 avoids water vapour from entering capacitor as last line of defense
The inside of shell 10 avoids Insulation stopping 30 because overly moist cause insulating properties to decline.The presence of connecting rod 57, so that rubber slab 55
It can deformation occurs in intermediate position stress.The setting of first blind hole 552 and the second blind hole 551, so that rubber slab 55 can only be at it
Central part is broken.For the accuracy for guaranteeing holes, the axis of the axis of first blind hole 552 and the second blind hole 551 is total
Line.The cone angle of first blind hole 552 is less than the cone angle of the second blind hole 551, and the maximum diameter of hole of first blind hole 552 is less than
The maximum diameter of hole of two blind holes 551；This makes the central part of rubber slab 55 be easier to be punctured by tapering 531 when stress is heaved.Institute
Stating inner tube 52 is round tube shape structure, and the maximum diameter of hole of first blind hole 552 is less than the internal diameter of inner tube 52.
When the inner cavity to outer tube 51 vacuumizes, if being not provided with counterweight column 53, in huge differential pressure action
Under, the central part of rubber slab 55 is easily popped；And counterweight column 53 can apply pressure to the central part of rubber slab 55, avoid
The central part of rubber slab 55 deforms in vacuumizing operation process, to effectively avoid 55 premature failure of rubber slab.
It further, is reduction resistance；It is clearance fit between 52 inner cavity of the counterweight column 53 and inner tube.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
