Abstract
The utility model relates to a high temperature resistance working capacitor for metal halide lamp, comprising an aluminum shell whose top is provided with an explosion prevention sheet and a chip group, gap in the aluminum shell is replete with semi-liquid soakage material, characterized in that the chip group is provided with a plastic inner shell outwardly, epoxy soakage material is filled between the chip group and the plastic inner shell. What differ the production structure of the utility model from the production structure of general product are as follow: the plastic inner shell is added, and epoxy is cast in the first place to isolate the chip group from the air; then the chip group sealed by epoxy (with the plastic inner shell) is placed within the aluminum shell for vacuum soakage, thus forming the production structure with above properties. The utility model has the advantages that usage temperature of the capacitor can run up to 10 DEG C, and reduction of capacity of the capacitor while being used is small, the service life is long.
Description
Technical field
The utility model relates to the correlative technology field of capacitor, specifically a kind of high temperature resistant Metal halogen lamp working capacitor.
Background technology
At present, the metal halide lamp (abbreviation Metal halogen lamp) of domestic each factory's production is made up of following several parts with working capacitor: be full of semiliquid impregnant, outsourcing insulation, aluminium shell in cap assembly, burst disk, core group, the aluminum hull.Again according to following operation: after capacitor core was assembled into aluminum hull, crimping sealed-vacuum impregnation (semi-liquid material)-oil sealing eye-cleaning-finished product test-sign, makes the capacitor finished product.The maximum operation (service) temperature of this capacitor is 105 ℃, and the minimizing of discovery capacity is more in using, and useful life is short, causes Metal halogen lamp from putting out easily.
For this reason, need on the basis of former capacitor, improve product structure, improve the technology of critical process simultaneously, develop serviceability temperature and can reach 110 ℃, and capacity reduces less in using, the high temperature resistant Metal halogen lamp working capacitor that useful life is long is to fill up domestic blank.
The utility model content
The purpose of this utility model has provided a kind of high temperature resistant Metal halogen lamp working capacitor, solved the working capacitor maximum operation (service) temperature that traditional metal halide lamp uses and only be 105 ℃, and the minimizing of discovery capacity is more in using, and useful life is short, causes Metal halogen lamp from the problem of putting out easily.
For achieving the above object, the utility model has adopted following technical scheme:
The utility model discloses a kind of high temperature resistant Metal halogen lamp working capacitor, comprise aluminum hull, the aluminum hull top is provided with the cap assembly, be provided with burst disk and core group in the aluminum hull, gap in the aluminum hull is full of the semiliquid impregnant, it is characterized in that: described core group is outside equipped with plastic inner shell, is full of the epoxy impregnation material between core group and plastic inner shell with the sealed core group.
The utility model product structure and mill run structure do not exist together as follows: increased plastic inner shell, and first cast epoxy, the core group is completely cut off with air fully; And then, form the product structure of above-mentioned characteristic with carrying out vacuum impregnation in the core group behind the epoxy sealing (the connecting plastic inner shell) aluminum hull of packing into together.
Advantage of the present utility model is: the capacitor serviceability temperature can reach 110 ℃, and the condenser capacity minimizing is less in using, long service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
A kind of high temperature resistant Metal halogen lamp working capacitor, as shown in Figure 1, comprise aluminum hull 1, aluminum hull 1 top is provided with cap assembly 2, be provided with burst disk 3 and core group 4 in the aluminum hull 1, gap in the aluminum hull 1 is full of semiliquid impregnant 5, and it is characterized in that: described core group 4 is outside equipped with plastic inner shell 6, and 6 of core group 4 and plastic inner shell are full of epoxy impregnation material 7 with sealed core group 4.
For obtaining above-mentioned improved products structure and good electrical properties and heat resistance, we have also done following improvement to manufacturing process.1, this product is earlier core to be assembled into plastic inner shell, pours into a mould epoxy fully deaeration under vacuum then, and heating makes curable epoxide, thereby makes the interior air of fuse seldom, and core group and outside air is isolated fully.Make that capacitor temperature rise in use is low, capacity reduces seldom, long service life.2, the core of again band being moulded shell is assembled in the aluminum hull, and crimping seals the back by the semi-liquid material of vacuum impregnation for the second time, makes it be full of space in the aluminum hull.When at high temperature using, these semi-liquid materials can be fused into liquid, thereby improve the capacitor heat dispersion greatly, play the effect of improving the capacitor serviceability temperature to a certain extent.
Since this product improvement structure, adopt the technology of secondary vacuum dipping simultaneously, thereby improved the performance of capacitor significantly.Be below this product 1.25 times of rated voltages, the volume change data that after endurance test in 600 hours, record under 110 ℃ of ambient temperatures.
