Description
Technical field
The utility model belongs to aluminium electrolutic capacitor field, the more particularly to a kind of impulse high voltage of resistance to transient overvoltage aluminium electroloysis
Capacitor.
Background technology
For convertible frequency air-conditioner products application, the past, there are a mistaken ideas, always considered that air-conditioning is strong using seasonality, and the time is short,
In addition cost pressure is big, therefore, 85 DEG C of common product, the common product of 400V, the common product of 450V etc. can be generally selected in past type selecting.
In fact, it for air conditioning applications, first has to fully take into account use environment extreme conditions, such as：
(1) mounted on balcony in the south, the summer long-time sun is exposed to the sun, and causes Product environment temperature just higher；
(2) for some remote districts, since voltage ripple of power network is bigger, there is overvoltage or overcurrent, will lead
Interiors of products is caused seriously to generate heat；Eventually lead to large capacitor failure；
(3) if ambient atmosphere pollution is more severe, such as long-term existence, some halogen-containing gases, can also seriously affect electricity
The service life of container；
(4) many domestic conditions are superior now, and winter, air-conditioning available machine time in summer are very long, have surmounted past design
Imagine.
Therefore, it is necessary to developing a kind of new aluminium electrolutic capacitor adapts to the new demand that air-conditioning uses.
Invention content
The technical problem to be solved by the utility model is to provide a kind of impulse high voltage of resistance to transient overvoltage alminium electrolytic condensers
Device, the capacitor enhance the ability of resistance to transient overvoltage relative to common aluminium electrolutic capacitor, reduce product market fraction defective,
Normal operation under the conditions of India, southeast asian market spread of voltage can be met.
The utility model provides a kind of impulse high voltage of resistance to transient overvoltage aluminium electrolutic capacitor, including shell, inner casing, envelope
Gate material, anode paillon, cathode paillon and electrolytic paper；The joint filling material is packed into inner casing and forms sealing, the inner casing and shell
Mating assembling, the anode paillon, cathode paillon and electrolytic paper are set to inner housing inner and form core packet, and the anode paillon is born
Pole paillon is fixed on the both sides of electrolytic paper；The electrolytic paper forms core using cotton pulp extrusion coating paper winding anode paillon, cathode paillon
Packet.
40 μm of paper in the electrolytic paper select cotton pulp extrusion coating paper, and ESR reduces by 12% than common.
The anode paillon and cathode paillon are low-leakage current formed aluminum foil.The V-I characteristics of the formed aluminum foil are very superior,
Product leakage current is small, and resistance to overvoltage ability is strong.
The anode paillon and cathode paillon are by being fixed by caulking to the both sides of electrolytic paper.
The anode paillon and cathode paillon are fixed on the both sides of electrolytic paper by Cold welding.
Advantageous effect
The utility model enhances the ability of resistance to transient overvoltage relative to common aluminium electrolutic capacitor, reduces product market
Fraction defective can meet normal operation under the conditions of India, southeast asian market spread of voltage；Surge voltage meets 550V, resistance to wink
Between overvoltage meet 620V (1 minute), have a good application prospect.
