Abstract
The utility model relates to a large ripple resistant aluminum electrolytic capacitor. Due to a bidirectional leading-out structure in an ultralow internal resistance and resistant to high ripple current, and the design that the width of each of a positive piece or a negative piece is larger than the width of barrier paper, the problems that equivalent series resistance is increased in a traditional leading-out connection manner and that heating is severe because of application of ripple current are solved. The large ripple resistant aluminum electrolytic capacitor has the advantages including novel structure, reliable performance, ultralow equivalent series resistance, and high bearing ripple current.
Description
Technical field
The utility model relates to a kind of aluminium electrolytic capacitor, specifically, is a kind of anti-large ripple aluminium electrolytic capacitor.
Background technology
Capacitor is the requisite elements of various electronic product terminals, plays vital effect in electronic system.In industry, power supply etc. were used, system manufacturer was more urgent to the demand of the capacitor of, low ESR, small size, and in automobile, military project and Aero-Space etc. are used, to capacitor life-span, high power capacity is withstand voltage, reliability etc. is had higher requirement.
In recent years, be rapidly developed in recent years take wind energy, solar energy as the power technology of representative.Frequency converter and the inverter in solar power system at wind generator system all need to use aluminium electrolytic capacitor, fast development along with wind energy, solar power generation industry, ultra-low equivalent series resistance has been proposed aluminium electrolytic capacitor, the requirement of anti-high ripple current and extra long life.
The lead-out mode that traditional bolt-type aluminum electrolytic capacitor adopts is unidirectional drawing, lead-out mode adopts many to aluminium matter lead and cover plate machine riveting, traditional connected mode of drawing increases the inside equivalent series resistance of capacitor, capacitor causes heating serious owing to having applied ripple current when work, thus the useful life of having limited capacitor.
Summary of the invention
For overcoming defects, the purpose of this utility model is to provide a kind of anti-large ripple aluminium electrolytic capacitor, its structure novel structure, dependable performance solve traditional series resistance such as connected mode effect of drawing and increase, applied ripple current and cause the serious problem of generating heat.
The utility model realizes that the technical scheme of above-mentioned purpose is:
A kind of anti-large ripple aluminium electrolytic capacitor comprises positive plate, negative plate, barrier paper, core bag and aluminium shell, anodal leading-out terminal, seal, safe explosion-proof device, negative pole leading-out terminal; Barrier paper is between positive plate and negative plate, and the three is rolled into together core Bao Erxin bag and is arranged in the aluminium shell and is fixedly connected with the aluminium shell; Anodal leading-out terminal is drawn from the left side of aluminium shell and is isolated with seal between anodal leading-out terminal and aluminium shell and the negative pole leading-out terminal is drawn from the right side of aluminium shell and integrated connection between negative pole leading-out terminal and aluminium shell; Positive plate is fixedly connected with anodal leading-out terminal, and similarly, negative plate is fixedly connected with the negative pole leading-out terminal; The pattern of anodal leading-out terminal and negative pole leading-out terminal is all screw bolt-type, and safe explosion-proof device is arranged on the left side of aluminium shell, and the width of described positive plate and negative plate is greater than the width of barrier paper.
The utility model novel structure, dependable performance solve traditional series resistance such as connected mode effect of drawing and increase, applied ripple current and cause the serious problem of generating heat.The utlity model has ultralow equivalent series resistance, can bear very high ripple current, significantly extended the useful life of product.
