Description
Technical field:
The invention belongs to electronic applications, particularly relate to a kind of high-voltage capacitor with rectifying device.
Background technology:
The traditional microwave circuit mesohigh capacitor of prior art and high-voltage diode are that partial installation connects to form, like this because high-voltage diode exposes pollutions such as being subject to oil smoke and air plankton, make that the proof voltage intensity of diode is low, and then cause diode breakdown and scrap, thereby influence the normal operation of whole system.And the someone wants high-voltage capacitor and diode as one before, but owing to connect and the difficult problem of insulation aspect can't solve, and succeed.So the useful life of diode is short, a difficult problem that becomes industry useful life that how to protect diode, prolongs diode.
Summary of the invention:
The present invention is directed to above problem a kind of high-voltage capacitor that improves diode proof voltage intensity and prolong the band rectifying device in diode useful life is provided.
The present invention overcomes the above problems used technical scheme: a kind of high-voltage capacitor with band rectifying device of following structure is provided, it comprises shell, irritate insulating oil and the weld tabs that has in the capacitor, the openend of described shell is provided with lid, the inner chamber of shell is provided with capacitor core, two electrodes of described capacitor core are electrically connected with an end of two weld tabs respectively, and be provided with resistance between two electrodes, the other end of described weld tabs extends the outside of lid, be provided with silicagel pad between weld tabs and the lid, and weld tabs extend cover an end around be provided with insulating base, it also comprises the diode that places shell inner cavity, one end of described diode is electrically connected with capacitor core, the other end of diode is electrically connected with lid, between diode and the shell, be equipped with insulating board between diode and the lid and between diode and the weld tabs.
The electrode that one end of described diode is electrically connected with capacitor core in two electrodes of an end and capacitor core that are meant diode is electrically connected.
After adopting above structure, the present invention compared with prior art, because diode has been located in the can of high-voltage capacitor, and irritate in the high-voltage capacitor insulating oil is arranged, therefore the present invention in use, diode and air insulated, and the heat radiation and the insulating effect of insulating oil are arranged make the proof voltage intensity height and the long service life of diode in the high-voltage capacitor.

Below in conjunction with accompanying drawing and concrete embodiment, the present invention is described further, but the present invention is not limited only to following concrete embodiment:
A kind of high-voltage capacitor as shown in Figure 1 with rectifying device, it comprises shell 1, irritate insulating oil 10 and the weld tabs 3 that has in the capacitor, described shell 1 is tightly connected with lid 2, the inner chamber of shell 1 is provided with capacitor core 9, described capacitor core 9 is to be dielectric with kraft capacitor paper and polypropylene film, two aluminium foils are done electrode, two electrodes respectively with the end welding of two weld tabs 3, and be provided with discharge resistance 7 between two electrodes, weld with two electrodes respectively at the two ends of discharge resistance 7, the other end of described weld tabs 3 extends and covers 2 the outside, be provided with silicagel pad 5 between weld tabs 3 and the lid 2, and weld tabs 3 extend cover 2 one ends around be provided with insulating base 4, it also comprises the diode 8 that places shell 1 inner chamber, one end of described diode 8 and capacitor core 9 welding, the other end of diode 8 and lid 2 welding are between diode 8 and the shell 1, be equipped with insulating board 6 between diode 8 and the lid 2 and between diode 8 and the weld tabs 3.
One end of described diode 8 and capacitor core 9 welding are meant an end and the welding of the electrode in 9 two electrodes of capacitor core of diode 8.
Operation principle, as shown in Figure 2, press figure with the assembling of each element after, insulating oil 10 be injected into fill fullly by covering oilhole on 2 at last, and scolding tin oil sealing hole can be inserted in other circuit and be used.
