Abstract
The utility model discloses a DC support filter capacitor for an automobile, which is characterized in that a capacitor core is arranged in a shell, and the two ends of the capacitor core are welded with copper sheets used as leading-out lines; and the two leading-out lines are riveted with a frame to form two electrodes of the capacitor, and epoxy resin is filled around the capacitor core in the shell. The capacitor is suitable for oil-electric hybrid automobiles, and has small temperature rise when at work for a long time, and good filter effect.
Description
Technical field
The utility model relates to a kind of capacitor, relates in particular to the direct current support filtering capacitor that a kind of oil electric mixed dynamic automobile is used.
Background technology
Through the test of groping for many years, oil electric mixed dynamic (HEV) formally is established as the mainstream technology of automobile industry energy-saving and emission-reduction.Each automobile production commercial city constantly has new vehicle to introduce to the market quickening research and development, as Toyota general sharp this, the A5 of Cherry, the outstanding merit in Chang'an, BYD F3DM.
In the oil electric mixed dynamic automobile, there is an alternating current machine to provide main or auxiliary power for automobile.The electric energy that the electric energy of the battery stores on the automobile or generator produce is sent to inverter by a DC-link (DC-Link) circuit, is reverse into alternating current, as the power supply that is alternating current machine.In this DC-link circuit, must jumbo capacitor in parallel, be that inverter circuit provides support by its charge-discharge characteristic, the ripple current that the inverter circuit of filtering simultaneously produces prolongs useful life of storage battery.This capacitor is commonly called direct current and supports filtering capacitor.
Different inverter circuits supports filtering capacitor to direct current different requirements.This key reaction is on following parameter: ripple voltage, electric current, frequency, maximum impact voltage, peak inrush current, maximum current, self-inductance, equivalent series resistance (ESR), maximum operating temperature.The direct current that also is not specifically designed to the oil electric mixed dynamic automobile on the market supports filtering capacitor now, a lot of clients are only selecting capacitor according to voltage and capacity, tend to cause support/filter action not obvious, though or temporarily can use, but during long-term work, capacitor lost efficacy because of temperature rise is too high.Therefore press for a direct current that satisfies the requirement of oil electric mixed dynamic automobile specially and support filtering capacitor.
Summary of the invention
The utility model provides a kind of long-term work temperature rise little, and the automobile of good wave filtering effect supports filtering capacitor with direct current.
A kind of automobile that the utility model embodiment provides supports filtering capacitor with direct current, be provided with capacitor body in the enclosure, the two ends of described capacitor body are welded with copper sheet as lead-out wire, and two described lead-out wires are riveted to two electrodes that form capacitor on the framework; Be filled with epoxy resin around the capacitor body in the enclosure.
Further, described capacitor body constitutes by being wound into a cylindrical polypropylene film, and its two ends are coated with the layer of metal coating.
Further, described shell and framework are formed a dry-type encapsulated structure.
The utility model provides a kind of automobile to support filtering capacitor with direct current, compares with traditional similar capacitor, and its technical parameter is more suitable for being used for the oil electric mixed dynamic automobile.Major advantage shows:
1) have the ability of outstanding processing ripple current, the long-term work temperature rise is little, good wave filtering effect;
2) have extremely low self inductance and equivalent series resistance, the dV/dt function admirable makes capacitor have the favorable charge-discharge ability;
3) complete dry construction does not exist the withered problem of electrolyte of electrolytic capacitor, longer service life.
4) have bigger energy storage density, small product size is littler, and weight is lighter;
5) maximum operating temperature reaches 105 ℃, and existing plain edition has only 85 ℃, is more suitable for the operational environment of automotive interior;
6) install and fix and the mode of connection solid and reliable, the vibration proof performance is good.
Description of drawings
Fig. 1 is a kind of automobile of providing of the utility model embodiment supports filtering capacitor with direct current a structural representation.
Embodiment
For making the utility model easier to understand, the present invention is further elaborated below in conjunction with accompanying drawing, but the embodiment in the accompanying drawing does not constitute any restriction of the present utility model.
As shown in Figure 1, the utility model embodiment provides a kind of automobile to support filtering capacitor with direct current, in shell 1, be provided with capacitor body 2, the two ends of described capacitor body 2 are welded with copper sheet 3 as lead-out wire, and two described lead-out wires are riveted to two electrodes 5 that form capacitor on the framework 6 that an epoxy plate makes; Be filled with epoxy resin 4 around the capacitor body in the enclosure.Promptly the good assembly of welding is installed in the shell, casting epoxy resin allows epoxy resin cure up to the faucal position in the shell.
With the high temperature metallization polypropylene film, reeling becomes a cylinder, in two end face sprayings of cylinder layer of metal, forms capacitor body.
Described shell and framework are formed a dry-type encapsulated structure, and capacitor does not exist the withered problem of the electrolyte of electrolytic capacitor, longer service life.
The automobile that described oil electric mixed dynamic automobile is used supports filtering capacitor with direct current and has the ability of outstanding processing ripple current, and the long-term work temperature rise is little, good wave filtering effect; Also have extremely low self inductance and equivalent series resistance, the dV/dt function admirable makes capacitor have the favorable charge-discharge ability;
The above is a preferred implementation of the present utility model; certainly can not limit the interest field of the utility model with this; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvement and change, these improvement and change also are considered as protection range of the present utility model.
