Description
Technical field
The utility model relates to a kind of electrical components, and in particular to a kind of capacitor combined cap.
Background technique
With the development of domestic electrical electronics industry, the new energy such as SVG, photovoltaic, wind-powered electricity generation develop well.These current transformers
Manufacturing firm is numerous, more with electrolytic capacitor.As the ripple current characteristic of thin film capacitor is advantageous, current transformer has started
It, from now on can gradually steering thin film capacitor, market potential be larger with metallic film capacitor.
Existing low-voltage, low capacity power electronic capacitor be mainly cylindrical capacitor.
It is divided into oil immersed type in the middle part of this kind of capacitor at present, there is also the sealing performance of connecting terminal is poor, be easy to cause
Leakage of oil and the drawbacks of influence capacitor operational reliability and safety.In dry-type capacitor, voltage class is high, exists exhausted to shell
The problem of edge, while Structure of need is simple and convenient to operate.
Utility model content
In order to solve above-mentioned key technology, the utility model provides a kind of capacitor combined cap.
Technical solution used by the utility model solves the problems, such as is as follows.
Capacitor is made of shell, combined cap, center and the resin of filling.Combined cap is by lid, insulator, guide rod, sealing
Circle, insulating washer and fixture nut are constituted.Insulator is mounted in face is covered, and guide rod is set in insulator, the bottom of insulator and guide rod
Portion, which passes through, to be covered and covers upper seal, insulating washer and fixture nut, and when assembly tightens fixture nut.Sheathing material is aluminum material,
It is cylindrical.
Lid is aluminum material, and disc-shape has 2 hexagonal holes.The material of insulator is plastics, 2 cylinders of disjunctor
Structure, bottom are fluted.Guide rod material is brass, tin plating processing, " ten " shape, and guide rod upper part is M10 screw thread, and here is six
The platform of side shape, centre are polished rods, and lower end is the screw thread of M6, and least significant end has 1 cross through hole.Sealing ring material is silicon rubber,
40 ~ 45 degree of shore hardness, " mountain " shape has the through-hole of diameter 6mm, diameter 25mm among the column part of protrusion.Felt pad loop material
Material is epoxy plate, and round, there are through-hole, thickness 2mm, diameter 32mm in centre.Fixture nut material is copper, hexagon.
The depth of insulator bottom groove than the column part that sealing ring protrudes length more than 1mm, the width of groove with it is close
The thickness of the column part of seal protrusion is identical, and when assembly, which tightens fixture nut, both to be made just to combine closely, and reaches solution and seeps
The problem of oil leak.
The diameter of insulating washer is bigger than the diameter of sealing ring, increases effective creepage distance, meets Insulation Problems.
The utility model direct current capacitors structure is simple, good seal performance, also with stable, the more reliable property of operational safety
Advantage.

21- lid；22- insulator；23- guide rod；24- sealing ring；25- insulating washer；26- fixture nut.
Specific embodiment
The utility model is further described below in conjunction with the drawings and specific embodiments.
Visible in Fig. 1: capacitor is mainly by shell (1), combined cap (2), center (3) and resin (4) structure filled
At.
As can be seen from Fig. 2: combined cap (2) is by covering (21), insulator (22), guide rod (23), sealing ring (24), insulating washer
(25) it is constituted with fixture nut (26).Above mounted in lid (21), guide rod (23) is set in insulator (22) insulator (22), insulation
Sub (22) and the bottom of guide rod (23) pass through lid (22) and cover upper seal (24), insulating washer (25) and fixture nut (26),
Fixture nut is tightened when assembly.
From Fig. 3 and Fig. 4: lid (21) disc-shape；Insulator (22) is 2 cylindrical structures of disjunctor, bottom
Portion is fluted；Guide rod (23) is in " ten " shape, and guide rod upper part has screw thread, and here is the platform of hexagon, and centre is light
Bar, lower end have screw thread, and least significant end has 1 cross through hole；Sealing ring (24) is in " mountain " shape, is had among the column part of protrusion logical
Hole；Insulating washer (25) is circle, and there is through-hole in centre；Fixture nut (26) is hexagon.
The depth of insulator (22) bottom groove is 1mm more than the length for the column part that sealing ring (24) protrudes.Insulator
(22) width of bottom groove is identical as the thickness of column part that sealing ring (24) protrudes.When assembly, fixture nut is tightened
(26) make the two that can just combine closely, reach and solve the problems, such as leakage of oil.
The diameter of insulating washer (25) is bigger than the diameter of sealing ring (24), increases effective creepage distance, meets Insulation Problems.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in
Change or replacement, should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should
It is subject to the protection scope in claims.
