Abstract
A novel environment-friendly and efficient high-pressure traction energy-storage capacitor relates to capacitors, comprises a casing and a core covering group positioned in the casing, and is characterized in that a vacuum encapsulation layer is arranged between the casing and the core covering group, and the core covering group is formed by connecting core coverings in series or in parallel, and each core covering is wound to be cylindrical or flat by a polypropylene metallization film layer and a polyester film layer in an overlapping manner. Compared with the prior art, the polyester film layer is utilized to increase the thickness of insulating medium so that the withstand voltage value of the capacitor is greatly enhanced; according to the withstand voltage bearing value of the medium of the capacitor being 200Vdc/mum, the thickness of a normal polypropylene metallization film only is 4-12mum, whereas the thickness of the polyester film can achieve 18mum, so that higher voltage can be born, further the withstand voltage value can be greatly improved, and the volume is correspondingly reduced greatly; and the overlapping wound core coverings are adopted to form the capacitor, the number of the core coverings is less, and the welding points are less, therefore, the capacitor has small inductance, low inductance, even no inductance, as well as good self-healing performance.
Description
Technical field
The utility model relates to capacitor, is specifically related to a kind of novel environment friendly high-efficiency high pressure traction energy storage capacitor.
Background technology
High-voltage energy storage capacitor is divided into two kinds, and a kind of is that crosstalk is held in the papery, and another is an aluminum foil type electric capacity.Crosstalk is held and is adopted several paper capacitor bond pads to be cascaded in the papery, because solder joint is more, under heavy current impact, if certain any pad loose contact then can cause condenser failure.Even add the unit fuse, also can't accurately control and shove, when circuit occurs when unusual, have the situation that the too early fusing of capacitor maybe can't fuse and take place, the product safety coefficient is lower.
Aluminum foil type electric capacity is made up of aluminium foil, film, papery etc., and its plate is an aluminium foil, by the lead wire of a pair of alignment, middle lining insulation reaches the target of low inductance, the defective that aluminum foil type electric capacity exists is as follows: plate resistance is big, the concussion attenuation block of discharge, and portion of energy consumption is in plate; Lead wire is pressed on the aluminium foil plate, and contact resistance is big, and big electric current is by the pair of lead wires sheet during discharge, and sharp pounding between lead wire and aluminium foil is destroyed minor insulation, causes component breakdown, shortens the electric capacity life-span; Aluminium foil forms by the dilute sulfuric acid oxidation, exists the very big hidden danger of pollution.
The utility model content
Technical problem to be solved in the utility model is to provide the high novel environment friendly high-efficiency high pressure of good, the high pressure resistant value of a kind of not self-healing performance to draw energy storage capacitor.
Technical problem to be solved in the utility model realizes by the following technical solutions,
A kind of novel environment friendly high-efficiency high pressure traction energy storage capacitor, comprise shell and be positioned at the core package of shell, it is characterized in that: be provided with the vacuum encapsulation layer between described shell and the core package, described core package is in series or in parallel to form by the core bag, and described core bag is by the polypropylene layer of metallized film and polyester film is stacked is rolled into cylindrical or flat.
Described polypropylene layer of metallized film is two-layer, and the polyester rete is one deck, and ground floor from bottom to top is the polypropylene layer of metallized film, and its metal level makes progress, and the second layer is the polyester rete, and uppermost is the three-layer polypropylene layer of metallized film, and its metal level is downward.
Described polypropylene layer of metallized film is two-layer, the polyester rete is two-layer, ground floor from bottom to top is the polyester rete, the second layer is the polypropylene layer of metallized film, the 3rd layer is the polyester rete, uppermost is the 4th strata propylene layer of metallized film, and wherein the metal level of the second polypropylene layer of metallized film, the 4th strata propylene layer of metallized film is in the same way.
Be provided with castor oil as dummy stack in the described vacuum encapsulation layer.
The utility model at first utilizes up-coiler with polypropylene metalized film and the folded capacitor core bag that is wound into of polyester film when making; The folded capacitor core bag of spooling is placed in the vacuum drying oven, carries out vacuumize; Metal spraying is carried out to the outer surface and the both ends of the surface of capacitor core bag in dry back; A plurality of capacitor core bags are welded behind the metal spraying, the capacitor core package that welding is good is put into metal shell, and uses the castor oil embedding again.
The beneficial effects of the utility model are: the utility model compared with prior art, the utility model utilizes the polyester rete to increase dielectric thickness, strengthened the withstand voltage of capacitor greatly, withstand voltage bearing value according to the medium 200Vdc/ μ m of capacitor, the thickness of normal polypropylene metalized film has only 4～12 μ m, and the thickness of polyester media film is up to 18 μ m, can bear higher voltage, therefore go up the raising withstand voltage very significantly, volume correspondingly reduces greatly simultaneously, and adopts its core bag quantity of capacitor core bag composition capacitor of folded volume few, pad is few, its interior sensibility reciprocal of capacitor is little like this, low sense even noninductive, and self-healing performance is good.
