Abstract

The utility model relates to a safety capacitor, which relates to a capacitor structure which uses insulators as media and uses conductors as two pole plates to separate the insulators. The utility model is designed in order to solve the problems that the thickness of the media of the capacitor is small when the media are separated by the two pole plates, the media are easy to be broken down by big current, and electric field strength is decreased if the thickness of the media is big. The utility model is characterized in that the thickness of the leading-out ends (10) of the two pole plates (8) of a capacitor body (6) is bigger than that of the other end (11) and has the advantages that gradients formed by the leading-out ends (10) of the two pole plates (8) and the other end (11) are extended, the media (7) can resist big current and the electric field strength is increased. The utility model is safer in use, and is especially suitable for a laser pulse circuit as a safety pulse capacitor.

Description

Safety type capacitor

The utility model relates to a kind of capacitor, especially a kind of shock-resistant big electric current, the capacitor that power output is big.

The purpose of this utility model is to provide a kind of volume little, the electrical property excellence, and shock-resistant big electric current, power output is big, especially in impulse circuit, when pulse frequency reaches 200 times/second, can keep the capacitor of the original state of pulse forming line.

The purpose of this utility model is such realization: safety type capacitor, it comprises housing (1), insulated terminal (2), wire column (3), connecting conducting wire between two-plate and the wire column (4), insulating barrier (5) around the enclosure interior, it is characterized in that described capacitor body (6), be one and have dielectric layer (7) and pole plate (8), and roll the capacitor body of the Cylinder shape on plastics mandrel (9), and be arranged on the inside of the insulating barrier (5) of housing (1), and its two-plate (8) is by connecting conducting wire (4) and the top that is arranged on housing (1), the inner wire column (3) of insulated terminal (2) links to each other.

Compared with prior art, advantage of the present utility model is, the two-plate of described capacitor body at the thickness of its exit thickness greater than the exit other end, makes the medium of capacitor have the proof voltage height concurrently, and shock-resistant electric current is big, uses safer.Except that being applied to impulse circuit, also can be widely used in capacitors such as filtering, energy storage, commutation as the pulse capacitor.

The utility model is described in further detail below in conjunction with drawings and Examples.
