Week is by spring banding；The interior oil package includes inner casing skeleton and inner casing forming part, is provided in the inner casing forming part secondary close
It seals lip and holds out against portion；Joint portion in the shell forming part is fixedly connected by bonding agent with inner casing skeleton, described to hold out against portion
Corresponding and shape matches with the position of the primary seal lip in shell forming part and the transition position between joint portion.
Further, the section of the outer casing framework and inner casing skeleton is L-shaped, and the inner casing skeleton includes flat section and sticks up
Section.
Further, the primary seal lip of shell forming part is located at the top that inner casing skeleton sticks up section on the outer casing framework.
Further, the joint portion in the shell forming part and the abutting edge of inner casing skeleton are particularly located at inner casing skeleton
Stick up a section outer wall.
Further, inner casing forming part holds out against portion and the primary seal lip in shell forming part and connects on the inner casing skeleton
Transition position between conjunction portion is in close contact.
Further, the side that the secondary sealing lip in the inner casing forming part is directed away from primary seal lip is obliquely installed；Institute
The minimum diameter for stating primary seal lip is less than the minimum diameter of secondary sealing lip.
The utility model has the following beneficial effects: one kind can High-voltage-resistatransformer simple combination oil sealing, only by external oil sealing and inside
Oil sealing is constituted, and in the case where higher oil liquid pressure can be born without failing by guaranteeing, simplifies the structure of combination oil seal, therefore can
Difficulty of processing is greatly reduced, while the production cost of high-pressure resistant oil seal can be reduced.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the utility model is described in further detail.It should be appreciated that specific embodiment described herein is only to explain this
Utility model is not used to limit the utility model.
With reference to Fig. 1, one kind can High-voltage-resistatransformer simple combination oil sealing, be made of external oil sealing 1 and internal oil sealing 2；It is described outer
Portion's oil sealing 1 includes outer casing framework 11 and shell forming part 12, and primary seal lip 14 and engagement are provided in the shell forming part 12
Portion 13, the periphery of the primary seal lip 14 is by 15 banding of spring；The internal oil sealing 2 includes inner casing skeleton 21 and inner casing forming part
22, it is provided with secondary sealing lip 23 in the inner casing forming part 22 and holds out against portion 24；Joint portion 13 in the shell forming part 12
It is fixedly connected by bonding agent with inner casing skeleton 21, it is described to hold out against portion 24 and the primary seal lip 14 in shell forming part 12 and engage
The position of transition position between portion 13 is corresponding and shape matches.
The section of the outer casing framework 11 and inner casing skeleton 21 is L-shaped, and the inner casing skeleton 21 includes flat section 211 and sticks up
Section 212.
The primary seal lip 14 of shell forming part 12 is located at the top that inner casing skeleton 21 sticks up section 212 on the outer casing framework 11.
The abutting edge at joint portion 13 and inner casing skeleton 21 in the shell forming part 12 is particularly located at inner casing skeleton 21
Stick up 212 outer wall of section.
On the inner casing skeleton 21 primary seal lip 14 of inner casing forming part 22 held out against in portion 24 and shell forming part 12 and
Transition position between joint portion 13 is in close contact, and the portion 24 that holds out against is for the transition between primary seal lip 14 and joint portion 13
Place forms and holds out against support.
The side that secondary sealing lip 23 in the inner casing forming part 22 is directed away from primary seal lip 14 is obliquely installed；The master
The minimum diameter of sealing lip 14 be less than secondary sealing lip 23 minimum diameter, the secondary sealing lip 23 for stop external dust or
