SU822299A1 - Pulse capacitor - Google Patents

Description

The invention relates to electrical engineering, in particular to high-voltage pulsed capacitors, and can be used to create powerful impulse current generators.

A capacitor is known, comprising a housing with parallel-connected cylindrical sections with protruding plates and two end contacts, one of which is a housing, the other is made in the form of a metal washer with a central rod insulated from the housing l.

The disadvantage of this construction is that it allows only two cylindrical sections to be connected in parallel.

. The closest in technical essence to the present invention is a pulsed capacitor, comprising a case with cylindrical sections placed in it, with protruding plates and two end contacts made in the form of strips of foil with a bent end, in one of which the ends are turned to the center, friend to the outer circumferential section and soldered cooTBOTCTBOHFjo to the central terminal and housing.

The disadvantages of this design is its low reliability, due to the complexity of parallel connection of a large number of sections with minimal distances between their ends, since it is necessary to make a connection by soldering the lower end of the subsequent section to the central outlet or housing.

0 In addition, foil strips, attached to the central outlet and the housing, cannot ensure the removal of a large amount of heat when a capacitor with an increased pulse tracking frequency is used. When using this design of the capacitor in the mode, when the rate of change

sparking between individual ends of adjacent foil of the same polarity, not covered by current collection.

The purpose of the invention is to increase reliability.

To achieve this goal, a pulse capacitor, comprising a housing, cylindrical sections with protruding plates and. end pins: 1ktam, center and side

0 pins, provided with an elastic strut, an elastic fastener, a corrugated sleeve with a concave wall and insulating sleeves, the insulating sleeves being located between the central terminal and the cylindrical sections, and the end contacts of each section are made in the form of metallic glasses with holes in the bottom , at the same time, on the side surface of one of the glasses, corrugated arched protrusions are made, pressed against the case of the condenser by an elastic spacing, and inside the second glass a corrugated sleeve is fixed, pressed to the central output by an elastic stitch. The drawing shows a pulse capacitor, a longitudinal section. The pulse capacitor contains a housing 1, in which cylindrical sections 2 with protruding plates and end contacts 3 and 4, a cover 5, an isolator b and a central outlet 7 are located. The side output is housing 1. The end contacts 3 and 4 are made in the form of two metal cups facing each other, with axial holes in the bottoms through which the central terminal 7 passes. The side surface 8 of one glass is pressed to the housing 1 (side terminal) of the condenser by corrugated arcuate protrusions, from the inside of which A springy strut 9 is installed. Inside the second cup 4, along its axis, a corrugated sleeve 10 is rigidly mounted, which, with its arcuate protrusions, is pressed to the central terminal 7. by means of an elastic fastener 11. and 16 of the required diameter. During operation, all sections are connected in parallel to the operating voltage of the capacitor. With intense heat generation in the sections of the capacitor, massive end contacts in contact with the capacitor case provide intensive heat transfer from the center of the section to the case only for metal. The temperature difference between the center of the section and the water cooled body does not exceed 18, which is 4 times less than the known capacitor designs. Using the proposed design, due to the face contacts in the form of metal cups in contact with the central side terminals, a reliable pulse capacitor with a working voltage of 5 kV and a capacity of 100 µF, with a specific energy of 100 J / dm, allowing operation with 100 imp / s and higher with minimal overheating. Claims of the invention A pulsed capacitor comprising a body, cylindrical sections with protruding plates and end contacts, central and lateral leads, distinguished by the fact that, in order to increase reliability, it is equipped with an elastic strut, an elastic tie, a corrugated sleeve with a concave wall and insulating bushings, the insulating sleeves being located between the central terminal and the cylindrical sections, and the end contacts of each section are made in the form of metal cups with holes in the bottom part, This on the side surface of a cup made corrugated, arcuate protrusions pressed against the body of the capacitor elastic spacer, and fixed inside the second cup corrugated sleeve, is pressed against the central terminal zhkoy elastic article.
