Abstract

A double-series capacitor bank relates to the capacitor technology field; two sets of capacitor cores with same numbers and equal capacitance are firstly connected in parallel and then connected in series to from the capacitor bank; capacitor core end faces on the backside of the capacitor bank are transversely connected through parallel copper bars; two ends of the parallel copper bars are vertically connected by two copper twisted wires; one copper twisted wire is led out from each capacitor core end face on the front side of the capacitor bank, the copper twisted wires with a number consistent with that of the cores are uniformly divided into two parts and are gathered into two electrode lead-out buses; and the middle of the front side of the capacitor bank is isolated by an insulation layer. A plurality of parallel copper bars are employed on the backside of the capacitor bank, and a cross section of the copper bar needs not to be big; and the copper bar can be better welded than copper wires, so a welding time is shorter. The vertical copper twisted wires connecting the parallel copper bars are welded on the copper bar, and will not affect the capacitor cores. One copper twisted wire is led out from each capacitor core on the front side of the capacitor bank; and the wire diameter of the copper twisted wire is not thick, so the copper twisted wire is easy to be welded, and uses short welding time. Service life of the capacitor can be ensured by employing the structure.

Description

Two series capacitor bank

Technical field

The utility model relates to the capacitor technology field, is specifically related to a kind of by series capacitors group again after the parallel connection of many metallic film capacitor fuses.

Background technology

At present, many capacitors are back in parallel series capacitors groups earlier, use the very big copper cash of sectional area to be connected between capacitor body and draw.Because the sectional area of copper cash is very big, when being connected with the capacitor body end face, need to use a lot of soldering tin materials, use the time of flatiron welding also very long.

The temperature tolerance of organic film is generally more than 100 degree centigrade, if the direct contact membrane of electric iron of welding can directly be scalded film.During actual welding, what contact with electric iron is gilding layer on the capacitor body end face.The composition of gilding layer is generally metal or their alloys such as zinc, tin, and thickness is generally about 0.5mm.Because gilding layer is thinner, if lack (as less than 10 seconds) weld time, welding if the time is longer, then can be damaged to film, thereby increase the loss of capacitor not influence of the film under the gilding layer, influences the useful life of capacitor.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of time that reduces the capacitor bond pads, and the loss of capacitor body can not increased unusually, guarantees capacitor two series capacitor bank in useful life.

Technical problem to be solved in the utility model realizes by the following technical solutions:

A kind of two series capacitor bank, described capacitor group is identical by two groups of quantity, after the capacitor body parallel connection that capacitance equates, be in series again, it is characterized in that: each capacitor body end face at the described capacitor group back side laterally connects by parallel copper bar, the two ends of described parallel copper bar are vertically connected by two copper stranded conductors, every capacitor body end face in described capacitor group front is all drawn a copper stranded conductor, the copper stranded conductor consistent with the capacitor core quantum count is divided into two parts, accumulate two electrodes and draw bus, the positive center of described capacitor group is insulated layer and separates.

In order to prevent capacitor group two series connection partial short circuits, be insulated layer 6 in the positive center of capacitor group and separate, it is the best that insulating barrier 6 cuts off with T shape, namely inserts between the capacitor body sidewall it is separated, the terminal with the both sides fuse covers in then.

Insulating barrier should have the good insulation performance characteristic, and heat-resisting, oil resistant can be selected plastic film, insulation wrap film, fish paper, cable paper etc. for use.

When capacitor core assembly quantum count more after a little while, the copper stranded conductor that can use that laterally connects connects, and does not use parallel copper bar.

The beneficial effects of the utility model are: many parallel copper bars have been used at the capacitor group back side in this structure, and its sectional area does not need too big, and than the better welding of copper cash, weld time is shorter.The vertical copper stranded conductor that connects parallel copper bar is to be welded on the copper bar, can not have influence on capacitor body.Positive every the capacitor body of capacitor group is drawn a copper stranded conductor, and the line footpath can be too not thick, welding easily, and weld time is short.Use this structure can guarantee the useful life of capacitor.
