Technical field
The utility model relates to a kind of capacitor device for power equipment etc., and the multiple capacitor elements that are made up of dielectric and the electrode foil of the sheet plain body that configuration forms is side by side made together with dielectric is sealing in canister.
Background technology
About prior art, describe with Fig. 3.Fig. 3 represents the formation of capacitor device 1.Accommodating capacitor element 3 in the inside of metal container 2.Capacitor element 3, after clamping multiple capacitor elements by integrated board, braces and utilizes insulating paper 4 to pack by congregation zone.Upper surface at capacitor element 3 is derived leading-out terminal 5.And the formation of capacitor element has been disclosed in patent documentation 1 grade.
After capacitor element 3 is contained in to the inside of container 2, baffle 6 is disposed to the upper surface of capacitor element 3.And, cover plate (not shown) is disposed to the top of container 2, surrounding's utilization welding of cover plate and container and engaging.Baffle 6 is for strengthening the insulation of capacitor element 3 and container 2, and in the time that bridge welding is connected to container, is not subject to the impact of sputter for the protection of the insulating paper 4 of covering capacitor element body 3.And, thereby capacitor device 1 is made in the inside that dielectric is enclosed container.In addition, safeties described later (not shown) are installed in capacitor device 1.
Then, safeties are described.In capacitor device, can there is the abnormal of unknown cause or rise container and expand because of interior pressing.Use the object of safeties to be to prevent that container expands and breaks as described.Safeties utilize the pressure rise of internal tank or the expansion of container to cut off the electric current of capacitor device.In safeties, have the pressure switch form of working pressure switch, maybe by be installed on internal tank cut-out substrate film cut off cut-out substrate film form.Pressure switch form is cut off electric current by the pressure rise of pressure switch Sensing container inside.Cutting off substrate film form is that utilization is followed the pressure rise of internal tank and caused container to expand.And the formation of a kind of safeties that cut off substrate film form of the prior art has been disclosed in patent documentation 2 grades.
The safeties 7 that cut off substrate film form are described with Fig. 2.Metallic plate is the bending of L word shape by mounting panel 8, at the upper surface of mounting panel 8,2 insulation boards 9 is installed.Use 2 groups of mounting panels 8 that insulation board 9 is installed, be disposed at the top of capacitor element 3.The mode of cutting off substrate film 10 to clip between 2 insulation boards 9 arranges.Insertion section 11 is being set on mounting panel 8, by insertion section 11 is inserted in the fixing metal part 12 of the inside that is installed on container 2, and safeties 7 is being fixed on to container 2.Cutting off substrate film 10 utilizes wire (not shown) that its two ends are connected to capacitor element 3 and leading-out terminal 5.
Effect to the safeties 7 that cut off substrate film form describes.In capacitor device 1 the abnormal generation of unknown cause or because of interior press rise cause container 2 to expand.Mounting panel 8 is fixed on container 2 via fixing metal part 12, thereby, if container 2 expands, cut off substrate film 10 to be stretched, can be cut off soon.Cut off substrate film 10 and be electrically connected between capacitor element 3 and leading-out terminal 5 via wire, thereby become the path of electric current, if thereby cut-out substrate film 10 be cut off, electric current also can be cut off.

Utility model content
The technical problems to be solved in the utility model
When wanting in the capacitor device that the safeties of setting pressure switch form form, when the safeties that cut off substrate film form are installed, exist baffle to disturb the insulation board of safeties or cut off substrate film and the problem that cannot install occurs.
If can not baffle be installed at the upper surface of capacitor element, the insulation of container and capacitor element cannot be enhanced, thereby causes the reliability of capacitor device to reduce.And in the time that bridge welding is connected to container, the insulating paper of covering capacitor element body is likely because sputter is damaged, this breakage also can cause the reliability of capacitor device to reduce.
The technological means of taking for technical solution problem
Of the present utility model being characterised in that: the safeties and the baffle that accommodating capacitor element in container, cut off substrate film form; and airtight and filling in the capacitor device of dielectric by cover plate, in the part of disturbing with described safeties of described baffle, notch is set.
The effect of utility model
Utilize the straightforward procedure of notch is set on baffle, need not increase capacitor device self and just can strengthen the insulation of capacitor element and container.And, can capacitor for voltage protection the impact of the insulating paper of the element body sputter while not being subject to cover plate with container welding, thereby just can realize the reliability raising of capacitor device with low cost.
