Abstract
The invention relates to a ceramic dielectric annular capacitor. The capacitor comprises a dielectric ceramic body 1 which has a cylindrical structure with a middle through hole, and is characterized by also comprising an inner lead ring 2 arranged on the inner ring surface of the dielectric ceramic body, and an outer lead ring 3 arranged on the outer side surface of the dielectric ceramic body, wherein the inner lead ring 2 and the outer lead ring 3 are isolated and staggered from each other, and an insulation section is formed between the inner lead ring 2 and the outer lead ring 3; and a clamping groove 4 is formed at the bottom of the inner ring surface of the dielectric ceramic body 1. The capacitor effectively solves the problem that the influence of a distance between pole plates of a cylindrical high-voltage ceramic capacitor on capacity and a creepage distance is mutually exclusive, has the function of shielding an electric field of a central cavity while the volume utilization rate of a sensor is improved, has small volume and a compact structure and is convenient and practical.
Description
Technical field
The present invention relates to a kind of electric capacity, especially relate to a kind of ceramic dielectric annular capacitor.
Background technology
The pottery high-voltage capacitance is the normal power taking sensing element that uses in the high-voltage alternating circuit.Because usually high-voltage capacitance is a cylindrical shape, and capacitor plate is on two relative disks.Make when the distance size that designs between the pole plate; Satisfying the selection that occurs contradiction on bigger creepage distance and the bigger capacitance value: for making the creepage distance long enough between pole plate; Should design enough cylinder height; But high more cylinder height, it is far away more that polar plate spacing is left, and causes the capacitance value more little.Simultaneously, capacitor is cooperated with other elements, lower in the utilization ratio of spatial volume, above defective has just proposed new requirement to the development and the improvement of electric capacity.For example, annular capacitor 0820179476.6 has adopted the annular stereo structure, but two electrodes can not solve the volume size and the two interelectrode creep distance sizes contradiction big or small with capacitance of capacitance material all at inner ring surface, can not be adapted to high pressure power taking occasion.
Summary of the invention
Problem the object of the present invention is to provide a kind of ceramic dielectric annular capacitor.
The technical scheme that the present invention is adopted for its technical problem of solution is:
A kind of ceramic dielectric annular capacitor; Comprise the dielectric ceramic body; Said dielectric ceramic body is the cylindrical configuration of middle perforation; It is characterized in that: also comprise the lead ring of being located at said dielectric ceramic body inner ring surface and the outer lead ring of being located at the external side of dielectric ceramic, said lead ring and outer lead ring are isolated each other.
Further, stagger each other between said lead ring and the outer lead ring, form an insulating segment between the two.
In addition, the bottom of said dielectric ceramic body inner ring surface is provided with the screens groove.
The invention has the beneficial effects as follows: the present invention is as a kind of ceramic dielectric annular capacitor; Because the one of which utmost point is arranged on the lead ring of ceramic dielectric inner ring surface, another utmost point is arranged on the outer lead ring of ceramic dielectric lateral surface, can be according to two ends of concrete needs adjustment die opening; Therefore for cylinder electric capacity; Can utilize the length of inside and outside anchor ring to increase creepage distance and pole plate area, the thickness of annulated column capable of using shortens the distance between capacitor plate simultaneously, between the bigger pole plate of acquisition in the creepage distance; Obtain the effect that increases capacitance, effectively solve the contradiction of pole plate apart from design; On the other hand, ceramic dielectric annular capacitor inside and outside circle cylinder pole plate of the present invention just in time can partly provide the shielding action to the electric field of outside for the cylindrical cavity of central authorities; The ceramic dielectric annular capacitor also has the electric field shielding function to center cavity when improving the sensor bulk utilance; In addition, therefore characteristics such as the present invention also has little, the compact conformation of volume, and is convenient and practical are fit to apply.
Description of drawings
Below in conjunction with accompanying drawing and specific embodiment the present invention is further specified:
Fig. 1 is an overall structure sketch map of the present invention;
Fig. 2 is a schematic top plan view of the present invention.
Embodiment
See figures.1.and.2; A kind of ceramic dielectric annular capacitor; Comprise dielectric ceramic body 1; Said dielectric ceramic body 1 is the cylindrical configuration of middle perforation, it is characterized in that: also comprise the lead ring 2 of being located at said dielectric ceramic body 1 inner ring surface and the outer lead ring 3 of being located at dielectric ceramic body 1 lateral surface, said lead ring 2 is isolated with outer lead ring 3 each other.
As preferred implementation of the present invention, stagger each other between said lead ring 2 and the outer lead ring 3, form an insulating segment between the two.
One utmost point of said ceramic dielectric annular capacitor is arranged on the lead ring 2 of ceramic dielectric inner ring surface; Another utmost point is arranged on the outer lead ring 3 of ceramic dielectric lateral surface, as can be seen from Figure 1, one section insulation spacing district is arranged between said lead ring 2 and the outer lead ring 3; Can adjust two distances between the end utmost point according to actual needs; Therefore for common electric capacity, its creepage distance is bigger, and coefficient of safety is higher.
Ceramic dielectric annular capacitor of the present invention generally is used in the high-voltage alternating transducer.Can be used for directly from High Level AC Voltage, obtaining other circuit working usefulness of faint powered minor transducer, and the electric field shielding effect is provided for the voltage signal acquisition cuicuit of electronic sensor.For example, through with being used of resistance string, as the current limliting step-down part of the prime of high pressure electricity getting device; Ring electrode connects high voltage in this moment; Outer ring electrode connects low-voltage, and the maskable external electrical field is to the influence of central resistance string, thus the precision and the stability of raising voltage sampling.
In addition, the bottom of said dielectric ceramic body 1 inner ring surface is provided with screens groove 4.More than preferable enforcement of the present invention is specified; Certainly; The present invention can also adopt the form different with above-mentioned execution mode; Those of ordinary skill in the art should belong in protection scope of the present invention conversion of under the prerequisite of spirit of the present invention, being done that is equal to or corresponding the change.
