Impregnated paper capacitance type transformer sleeve (dry sleeve) the major insulation capacitor core of industry gluing at present is entirely whole pours
It infuses, especially extra-high die pressing product, glue impregnated paper capacitor core length is long, and diameter is big, and pouring technology is extremely complex, reacts
Shi Wendu is difficult to control, and qualification rate is very low, although some products have passed through delivery test, and in later period operation, defect exposure, draws
It has sent out more serious problem and has led to heavy losses.
Summary of the invention:
The present invention is to provide a kind of extra-high moulding impregnated paper alternating current-direct current condenser type to solve the above-mentioned problems of the prior art
Casing.
The technical solution adopted in the present invention has: a kind of extra-high moulding impregnated paper alternating current-direct current condenser-type terminal, including center are led
Body, interior capacitor core, outer capacitor core, external insulation and mounting flange, the interior capacitor core are mounted on outer capacitor core
On center conductor, and the lower end of interior capacitor core is plugged in outer capacitor core, zero screen and interior capacitor core of outer capacitor core
End shield between equipotential link-up；
External insulation and mounting flange, and outer capacitance core are arranged on the outer wall of interior capacitor core and on the outer wall of outer capacitor core
The end of son is fixedly connected with the mounting flange on interior capacitor core by screw；
Capacitor tap is equipped on the mounting flange of outer capacitor core, capacitor tap is connected with the end shield of outer capacitor core.
Further, shading ring and sealing ring are equipped at the lower end cooperation of the interior capacitor core and outer capacitor core.
Further, the material of the external insulation uses silicon rubber composite sheath or insulator.
Further, between the external insulation and interior capacitor core and external insulation and outer capacitor core are filled with insulation silicone grease
Or insulating gas.
Further, the end of the interior capacitor core and the end of outer capacitor core are equipped with connection end seat.
Further, the connection end seat is made of aluminium alloy, is equipped with connecting hole in connection end seat.
The invention has the following beneficial effects:
The casting difficulty of major insulation capacitor core can be effectively reduced in the present invention, greatly improves major insulation capacitor core qualification rate,
Weight saving, cost reduce.
Detailed description of the invention:
Fig. 1 is structure of the invention figure.
Specific embodiment:
The present invention will be further described below with reference to the drawings.
As shown in Figure 1, a kind of extra-high moulding impregnated paper alternating current-direct current condenser-type terminal of the present invention, including center conductor 1, interior capacitor
Fuse 21, outer capacitor core 22, external insulation 3 and mounting flange 4, interior capacitor core 21 are mounted on center with outer capacitor core 22
On conductor 1, and the lower end of interior capacitor core 21 is plugged in outer capacitor core 22, zero screen and interior capacitance core of outer capacitor core 22
Equipotential link-up between the end shield of son 21.It is arranged on the outer wall of interior capacitor core 21 and on the outer wall of outer capacitor core 22 outer
Insulation 3 and mounting flange 4, and the end of outer capacitor core 22 is fixed with the mounting flange 4 on interior capacitor core 21 by screw
It connects and seals.Capacitor tap 7, capacitor tap 7 and outer capacitor core 22 are equipped on the mounting flange 4 of outer capacitor core 22
End shield is connected.
Shading ring 6 and sealing ring are equipped at the lower end cooperation of interior capacitor core 21 and outer capacitor core 22.
The material of external insulation 3 use silicon rubber composite sheath or insulator, between external insulation and interior capacitor core 21 and
External insulation and outer capacitor core 22 are filled with insulation silicone grease or insulating gas.
The end of interior capacitor core 21 and the end of outer capacitor core 22 are equipped with connection end seat.It connects end seat and uses aluminium
Alloy is made, and is equipped with connecting hole in connection end seat.In the connection end seat of outer 22 end of capacitor core and interior capacitor core 21
Mounting flange 4 is fixedly connected and is sealed by screw.
The condenser type fuse that glue impregnated paper capacitor core is independently produced by two is coaxially connected in series by the present invention (can also be by
It is multiple), interior 21 diameter of capacitor core is small, and length is long；Outer 22 diameter of capacitor core is big, and length is short.Interior capacitor core 21 it is outermost
Equipotential link-up between layer capacitance screen and outer capacitor core innermost layer capacitance plate 22, there is the shading ring of equipotential link in casing tail portion
6, the capacitor core of composition and integrated poured capacitor core field distribution are completely the same.The capacitor core of one entirety is divided into
Two parts are poured, and can solve conventional capacitance fuse because improving main exhausted the problem of the bad control of the big pouring technology of size
The qualification rate of edge capacitor core, while reducing because of waste of material caused by equipment limit.
External insulation 3 is silicon rubber composite sheath or insulator, is divided into two parts (being also possible to an entirety), respectively with it is interior
Side and the cooperation of capacitance outside fuse size and shape, two parts external insulation junction can by with two capacitor cores etc. it is electric
Position connection place is shorted, and achievees the purpose that uniform electric field.It is filled with insulation silicone grease or insulating gas between core and external insulation, meets gas
