Capacitor.
Background technology
With continuing to develop for China's economy, pollution problem is also increasingly serious, and China's economic development policy is also gradually to ring
Protect industrial slope in investment.Enhancing with country to energy-conserving and environment-protective demand, simultaneously because the development of Power Electronic Technique, electrostatic precipitation row
Industry gradually develops into more advanced high frequency electric source by traditional power frequency supply, then to more efficient more energy efficient high-voltage pulse electric precipitation side
Formula, to more preferable effects of energy conservation and environmental protection can be reached.
In order to coordinate the development of high-voltage pulse electric dust-removing power supply, its supporting high voltage thin film electric capacity is researched and developed.By to reality
Substantial amounts of research work has been done in the Microsecond grade pulse power supply technology of the electric cleaner of application and application.It uses energy-storing-type principle,
There are significant power saving advantages.Its canonical parameter is the μ s of pulse width 70 ~ 200,25 ~ 400pps of pulse recurrence frequency, basic direct current
Voltage 40kV, pulse peak-peak voltage 80kV.
In this application scenario, the requirement to electric capacity is just very high.The rated voltage requirement 80kV ~ 100kV of electric capacity, discharge and recharge
Frequency requirement reach 10 ~ 50kHz, discharge current reaches 100 ~ 500A.
Although conventional thin-film capacitor has good adaptability, but general its uses voltage in below 3kV, to reach 80kV
Use voltage must be very many capacitances in series, while the frequency requirement that cannot meet discharge and recharge reaches 10 ~ 50kHz, electric discharge
Electric current reaches the use requirement of 100 ~ 500A.
General high voltage pulsed capacitance can be using the structure of metal foil oil formula, but such product has the disadvantage that volume weight is excessive,
There is oil leak risk, be unfavorable for the reliable and stable operation of equipment.
The content of the invention
In order to solve the above problems, the utility model provides a kind of dry type film electric capacity for being applied to pulse dust removal field
Device, its application conditions that disclosure satisfy that high voltage, high current and high charge-discharge frequency.
Its technical scheme is such：A kind of dry type film capacitor for being applied to pulse dust removal field, it includes housing,
Potting compound, left side fuse group and right side fuse group, the left side fuse group and the right side fuse group are provided with the housing
Between be provided with insulation board, the left side fuse group and the right side fuse group are by welding copper coin connection electrode, the left side
Side core subgroup includes the single subgroup of two groups and connecting welding with the right side fuse group respectively, and the single subgroup is by least four
Individual capacitor core is in series, and includes at least ten string metallized films in the capacitor core, the left side fuse group and described
Right side fuse group concatenation connection, is coated with aluminium film on the metallized film of the capacitor core, the aluminium film edges at two ends is thickening
Layer.
It is further characterized by, and the potting compound is heat conductive flame-retarding epoxy；
The housing is plastic alloy housing；
The electrode is copper nut or brass bolt；
Connected by copper plate between the capacitor core；
Connected by copper bar or braiding copper strips between the capacitor core and the electrode.
After structure of the present utility model, internal many string membrane structures, while being connected into single between capacitor core
In parallel again after group, last left side fuse group and right side fuse group are together in series again, are finally reached the structure of many string series connection, greatly
The field intensity for reducing one layer metallization film it is pressure-resistant, while can cause that the pulse current of capacitor core is greatly enhanced, so
Single thin-film capacitor undertension is solved the problems, such as, the application conditions of super-pressure 80kV ~ 100kV is met, on metallized film
It is coated with aluminium film, and aluminium film edges at two ends is thickening layer, while metallized film is had higher pressure-resistant, there is greatly excessively electric
Stream ability, meets discharge and recharge frequency high（10~50kHz）, the big problem of pulse current.

Specific embodiment
See Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4, a kind of dry type film capacitor for being applied to pulse dust removal field, it includes shell
Body 1, is provided with potting compound 4 in housing 1, left side fuse group 31 and right side fuse group 32, left side fuse group 31 and right side fuse group
Insulation board 6 is provided between 32 so that left side fuse group and right side fuse group separate increase creep age distance, the He of left side fuse group 31
By welding the connection electrode 2 of copper coin 5, left side fuse group 31 includes two groups simultaneously to right side fuse group 32 respectively with right side fuse group 32
The single subgroup of connecting welding, single subgroup is in series by four capacitor cores 3, and at least ten string gold are included in capacitor core 3
Categoryization film 7, left side fuse group 31 and right side fuse group 32 concatenate connection, and aluminium film is coated with the metallized film 7 of capacitor core 3
8, the edges at two ends of aluminium film 8 is thickening layer 9.
Potting compound 4 must use metal foil, gold using traditional high-voltage capacitor after dry type heat conductive flame-retarding epoxy, is changed
The mentality of designing of category shell and oily formula, housing 1 employs plastic alloy housing, leakage and flammable problem will not occur, safely may be used
Lean on, electrode 2 employs copper nut or brass bolt, connected by copper plate between capacitor core 4, between capacitor core 4 and electrode 2
After copper bar or braiding copper strips are connected so that small product size weight greatly reduces, easier for installation.
The many string membrane structures in capacitor core inside（10 strings ~ 20 are gone here and there）Using newest thin film processing techniques, while using aluminium
Film coating processing mode, edge thickeies sheet resistance form, while metallized film is had higher pressure-resistant, there is great overcurrent
Ability, meets discharge and recharge frequency high（10~50kHz）, the big problem of pulse current.
