Abstract
The utility model relates to the improvement of a capacitor, particularly a rail compensation capacitor with a full sealing structure. The utility model comprises a shell body, a capacitor core which is arranged in the shell body, a pole plate on the capacitor core, a leading wire which is arranged on the pole plate and a shell cover which is connected with the shell body by sealing. A seal insulator is arranged at the threading hole point that the leading wire penetrates through the shell cover. The outside of the shell body is provided with a protective box, and insulation sealing materials are injected into the protective box. The seal insulator is welded on the shell cover, and the leading wire is led out from the insulator and is connected with an outer leading wire by a leading out end. The utility model has the advantages of economy, practicality, simple structure, safety, convenience and reliable and stable performance, and can be free from the influence of the external environment.
Description
Affiliated technical field:
The utility model belongs to the capacitor technology field, relates to a kind of improvement to capacitor, relates in particular to a kind of track compensating capacitor of all-sealed structure.
Background technology:
Present CBG type capacitor all is with capacitor body encapsulating compound (epoxy resin), be encapsulated in plastic casing, this product structure belongs to the semitight structure, the isolating exterior environment is to the influence of the main electrical performance indexes of capacitor fully, outside it, because external environment influence factor, performance to capacitor produces infringement, cause the product capacity decay, insulation resistance does not reach requirement, and tg δ increase etc. directly cause capacitor to lose efficacy, influence the stability of reliability of products and operation, cause the out of control of whole system.
Summary of the invention:
The purpose of this utility model is to overcome the deficiencies in the prior art and the track compensating capacitor that a kind of convenient and safe, strong operability is provided, is not affected by the external environment.
The purpose of this utility model is achieved in that and comprises housing, is arranged on capacitor body, the pole plate on the capacitor body in the housing, is arranged on the lead-in wire on the pole plate, the cap that is connected with housing seal; the place, hole that passes of passing cap at lead-in wire is provided with sealing insulator; be added with the protection box in the outside of housing, at the inner insulator seal material that injects of protection box.Sealing insulator is welded on the cap, and lead-in wire is drawn from insulator, and is connected with outer lead by exit.
The utlity model has economical and practical, simple in structure, be not affected by the external environment, safe ready, dependable performance, stable advantage.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
As shown in Figure 1; the cap 10 that the utility model comprises housing 1, be arranged on capacitor body 6, the pole plate 11 on the capacitor body 6 in the housing 1, be arranged on lead-in wire on the pole plate 11, be tightly connected with housing 1; the place, hole that passes of passing cap 10 at lead-in wire is provided with sealing insulator 9; be added with protection box 7 in the outside of housing 1, at the protection box 7 inner insulator seal material 8 that inject.Sealing insulator 9 is welded on the cap 10, and lead-in wire is drawn from insulator, and is connected with outer lead by exit 5.Described housing 1 is a nonmagnetic material.Described sealing insulator 9 is a pottery.2 is the welded seal place of housing 1 and cap 10, and 3 is the welded seal place of sealing insulator 9 and cap 10, and 4 are the welded seal places of lead-in wire with sealing insulator 9.
