Description
Technical field
The invention belongs to power capacitor field, be specifically related to a kind of noinductive capacitor.
Technical background
Capacitor, as the term suggests the device being a kind of stored charge, presss from both sides one deck insulation dielectric between two blocks of metal electrodes, when adding voltage between two metal electrodes, will stored charge on electrode, and so capacitor is energy-storage travelling wave tube.Capacitor effect in circuit widely, comprises coupling, filtering, resonance, integration, differential etc.
Power capacitor is being widely used in the various situations such as factory's distribution system, residential quarter distribution system, municipal commercial building, traffic tunnel distribution system, case change, complete cabinet, distributed board outdoor; But power capacitor is in current disturbing process, and can produce HTHP, there is potential safety hazard, therefore the explosion prevention function of capacitor is the function that must not lack.
Summary of the invention
Technical scheme to be solved by this invention is: provide a kind of capacitor, not only can be explosion-proof, can also prevent high temperature.
Technical scheme of the present invention is:
A kind of noinductive capacitor, comprises cylindrical tube, Explosion-proof cap assembly, capacitor body; Wherein Explosion-proof cap assembly comprises middle recessed aluminium lid, and is arranged on the binding post on aluminium lid, and binding post is fixed on aluminium lid by binding post insulating case and insulating case retainer plate, and insulate with aluminium lid; Bursting diaphragm is cylindrical tube shape, and cylinder edge props up aluminium lid edge, and the bottom surface of cylinder arranges bursting diaphragm conductive pole; Described bursting diaphragm conductive pole is connected by explosion-proof and thermoswitch with the hypomere of binding post.The other end of bursting diaphragm conductive pole connects capacitor core.
Further, described explosion-proof is middle narrow copper sheet, can limit, regulate the width at the narrow easily broken place of copper sheet according to required explosion-proof pressure.
The invention has the beneficial effects as follows: capacitor internal pressure increase, after increasing to certain pressure, aluminium lid is out of shape, explosion-proof under tension, and arrive certain pressure size, explosion-proof fracture, makes capacitor short-circuit.Meanwhile, be also provided with temperature detect switch (TDS), when capacitor produces amount of heat because being subject to big current, when causing temperature to exceed the work allowable temperature of capacitor, temperature detect switch (TDS) disconnects, and preventing continues to heat up causes the damage of capacitor.This temperature control process can restore, and after temperature lowers, capacitor recovers normal work.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
A kind of noinductive capacitor as shown in Figure 1, comprises cylindrical tube 1, Explosion-proof cap assembly 2, capacitor body 3; Wherein Explosion-proof cap assembly 2 comprises middle recessed aluminium lid 28, and concave configuration is the weak link of lid, under high pressure first deforms; Be arranged on the binding post 21 on aluminium lid 28, binding post 21 is fixed on aluminium lid 28 by binding post insulating case 22 and insulating case retainer plate 23, and binding post insulating case 22 completely cuts off binding post 21 and the contact of aluminium lid 28, is fixed by binding post 21 above aluminium lid 28; Insulating case retainer plate 23 with nut form at aluminium lid 28 bottom link post 21.Bursting diaphragm 26 is in cylindrical tube shape, and cylinder edge props up aluminium lid 28 edge, and the bottom surface of cylinder arranges bursting diaphragm conductive pole 27; When aluminium lid is because of high pressure generation deformation, deformation place is concave configuration, and the flat configuration at edge will remain unchanged shape; Thus bursting diaphragm keeps fixing in aluminium lid 28 deformation process, is the stiff end of explosion-proof.Described bursting diaphragm conductive pole 27 is connected by explosion-proof 24 and thermoswitch 25 with the hypomere of binding post 21; Explosion-proof 24 is middle narrow copper sheet, can limit, regulate the width at the narrow easily broken place of copper sheet according to required explosion-proof pressure; And thermoswitch 25 meeting automatic short-circuit under the limiting temperature of setting, capacitor for voltage protection.The other end of bursting diaphragm conductive pole 27 connects capacitor core 3.
More than show and describe general principle of the present invention, principal character and advantage of the present invention.The present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in claimed scope of the present invention.Application claims protection range is defined by appending claims and equivalent thereof.
