Abstract
The utility model relates to an environmental-protection low-voltage parallel-connection film capacitor, comprising a film, a housing and an electrode, wherein the film is formed by multilayer concentric winding. An anode and a cathode of the film are respectively connected with an anode and a cathode of the electrode. The housing mainly adopts a zinc-aluminium composite metallization-film material. An environmental-protection paint protection film is covered on an external surface of a zinc-aluminium composite metallization film by a high temperature technology. The film capacitor has the advantages of good anticorrosion and antirust performances, simple production technology, high production efficiency and long service life of products and is suitable for capacitors of low-voltage electrical-network power-factor compensation apparatuses.
Description
Technical field
The utility model relates to electronic element, specifically about a kind of diaphragm type electric power capacitor.The utility model is applicable to the capacitor of low voltage electric network power factor compensation device.
Background technology
Low pressure film capacitor in parallel is used for low voltage electric network and improves power factor, reduces line loss, improves quality of voltage.But existing capacitor product shell is divided into two kinds, and a kind of is that the surface lacquer another kind is surface frosted.The shell of surface lacquer has stronger rust-resisting property, but paint is aging coming off easily, if the Spray Painter or wipe clearly the worker will cause because of carelessness shell to spray paint inhomogeneous or cause the surface the false phenomenon of spraying paint, time one can make naked surface part cause corrosion for a long time, directly affects the useful life of capacitor.And benzene, first that painting process produces are stupid, the xylene pollutant injures human body and contaminated environment.The shell of surface frosted is only suitable for the interior fittings as reactive power compensator; because the noisy shell of mill is without the anticorrosive protective layer of rust-proofing; and all need in process of production operation element to wear gloves and can not allow shell be infected with water stain and may cause the pollutant that gets rusty and corrode; production process is had relatively high expectations, and affects production efficiency.
Summary of the invention
The purpose of this utility model is the shortcoming that exists for prior art, and a kind of anticorrosion, good antirust property, production technology is simple, production efficiency is high, life of product is long environmental protection low pressure film capacitor in parallel are provided.
The technical solution of the utility model comprises film, shell and electrode; thin-film multilayer is rolled into one heart; the positive and negative electrode of film is connected with the positive and negative electrode of electrode respectively; mainly be that shell adopts zinc-aluminium composition metal membrane material, scald by high-temperature technology at zinc-aluminium composition metal film outer surface and cover one deck environment protection oil paint diaphragm.
The utility model has the advantages that shell adopts zinc-aluminium composition metal film to scald by high-temperature technology and covers one deck
The environment protection oil paint diaphragm, it is anticorrosion, good antirust property, production technology is simple, production efficiency is high, life of product is long.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The film capacitor in parallel of environmental protection low pressure as shown in Figure 1; comprise film 4, shell 1 and electrode 3; film 4 multilayer concentrics are rolled into; the positive and negative electrode of film 4 is connected with the positive and negative electrode of electrode 3 respectively; shell 1 adopts zinc-aluminium composition metal membrane material, scalds by high-temperature technology at zinc-aluminium composition metal film outer surface and covers one deck environment protection oil paint diaphragm 2.This environment protection oil paint diaphragm 2 is in shell raw material manufacturing process; directly overlay on the metal level by high-temperature technology; and the two is combined together, and be equivalent to add layer protecting film to metal, avoiding manually sprays paint causes the waste of paint and the impact of environmental pollution and health of human body.In the course of processing, only needing that zinc-aluminium composition metal film is struck out the capacitor case shape can use, avoid the antiseptic property of the enamelled coating quality influence shell 1 that manually sprays paint, have environmental protection, anticorrosion, good antirust property, an advantage such as production efficiency is high, life of product is long.
