Problems solved by technology

[0003] In order to solve the problem that the requirement of the safety distance cannot be met by changing the margin distance or the utilization rate of the capacitor medium is seriously reduced by changing the margin distance when individual components in the capacitors connected in series bear higher voltage under special circumstances, the present invention provides a capacitor, The capacitive core of the capacitor has an insulating structure with polar plate offset, which fully guarantees the insulation requirements of the ends of each component under the premise of ensuring a reasonable use of the capacitor medium

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] The capacitor in this embodiment includes a high-voltage electrode 1, a ground electrode 2, and a capacitor core 5 between the high-voltage electrode 1 and the ground electrode 2. The capacitor core 5 includes a first pole plate 301, a second pole plate 32, and the same size. The third pole plate 33, the fourth pole plate 34 and the fifth pole plate 310, the capacitor core 5 also includes an insulating medium 4 positioned between adjacent pole plates, and the vertical distance between each insulating medium and the high voltage electrode 1 is the same , the height of the insulating medium 4 is greater than the height of the plate (defining the vertical direction between the high voltage electrode and the ground electrode as the height direction);

[0026] The first pole plate 301 is placed perpendicular to the high-voltage electrode 1, a...

Abstract

The invention relates to a capacitor, particularly relates to a capacitor having a pole plate offset structure capacitor core, and relates to a capacitor suitable for various environments of AC / DC high voltage. The capacitor comprises a high voltage electrode, a grounding electrode and the capacitor core which is arranged between the high voltage electrode and the grounding electrode. The e capacitor core comprises a first pole plate, an Nth pole plate and N-2 pole plates which are arranged between the first pole plate and the Nth pole plate, wherein all the pole plates are arranged in parallel in turn and identical in size. The capacitor core also comprises an insulating medium which is arranged between the adjacent pole plates and identical in size. The vertical distance between each insulating medium and the high voltage electrode is identical, and the vertical distance between each pole plate and the high voltage electrode is different. The problems that the requirement of safe distance cannot be achieved by changing the margin distance or the utilization rate of the capacitor media declines sharply due to the fact that the individual element in the series capacitor bears higher voltage under the special condition can be solved.

Description

technical field [0001] The invention relates to a capacitor, in particular to a capacitor with a capacitive core with a polar plate offset structure, which is suitable for capacitors used in various AC and DC high voltage environments. Background technique [0002] As we all know, the electric strength of a single component of a capacitor is limited. For capacitors used under high AC and DC voltages, the series connection of components must be used to ensure that the voltage resistance of the entire unit meets the requirements, and the end insulation of a single component is through the dielectric film 8 and The edge between the aluminum foil plates 7 is solved, the length of the edge is usually 3-10mm, and the structure is as follows Figure 5 shown. Since they are wound with the same design, the elements have the same withstand voltage level. However, in some special cases, due to the placement position, individual components will withstand higher voltages, and the margin...
