Description
Technical field
The invention belongs to controller switching equipment manufacturing technology fields, and in particular to a kind of system of solid sealing electrode pole of high voltage vacuum breaker
Preparation Method.
Background technology
High-pressure vacuum breaker is also very high to the requirement of its insulation degree because its voltage class is higher, otherwise holds very much
Easily influence the performance of breaker.Solid sealing electrode pole of high voltage vacuum breaker in the prior art, production technology exist very much
Deficiency uses insulated barrel-type mounting structure, vacuum interrupter is installed in insulating cylinder, and such structure is easy by air
In moisture, dust, condensation etc. influence, in addition, there are holes between vacuum interrupter and pole shell, to be easy production
Raw ionization puncture arc-chutes；In breaker interrupting process, the high-voltage arc that vacuum interrupter generates makes arc extinguishing room temperature increase,
Cause to expand with heat and contract with cold, can to generate relative displacement between vacuum interrupter and insulation crust, to generate hole, influence vacuum
The performance of arc-chutes.
For the above problem existing for existing high-pressure vacuum breaker, it is urgent to provide a kind of high-pressure vacuum breaker sealings
The preparation method of pole, to overcome the deficiencies in the prior art, so as to improve the performance of vacuum high-pressure breaker.
Invention content
The above problem existing for the existing high-pressure vacuum breaker of the present invention, provides a kind of high-pressure vacuum breaker sealing
The preparation method of pole is insufficient existing for the production technology of current solid sealing electrode pole of high voltage vacuum breaker to overcome.
To achieve the above object, the technical scheme is that：A kind of preparation work of solid sealing electrode pole of high voltage vacuum breaker
Skill includes the following steps：A, prepare mold：It is ranked sequentially according to lower core pulling, quiet mould, dynamic model, upper core pulling, ensures dynamic model and quiet
The positioning pin of mould and the positioning pin of lower core pulling are in the center of location hole；Be closed dynamic model, quiet mould and upper core pulling, under
Mould pressurizing is given in core pulling, and mold is made to be in packing state, and setting die gap is less than 0.04mm；
B, parts pre-process：Vacuum interrupter, upper wire outlet seat, lower wire outlet seat are cleaned with alcohol, remove zero
The greasy dirt and dust on part surface；
C, it preheats：Vacuum interrupter, upper wire outlet seat, lower wire outlet seat are put into oven, setting heating time is 2.5H；
D, dispensing：Choose epoxy resin, curing agent, silica flour, toner mass ratio be 1:1:4:0.05, it successively will solidification
Agent, epoxy resin, silica flour, toner are put into vacuum pressure agitator tank, and the material after mixing is stirred evenly, and extract agitator tank and are
Vacuum state, and vacuum state 20min is kept, setting whipping temp is 70 DEG C, mixing time 1.5H.
E, it is injection moulded：By in epoxy resin injection to mold, 160 DEG C of temperature is kept, pressure remains 0.5MPa, keeps
Pole demoulds after 20-30min, and the pole after depanning is cleared up, is corrected, is then placed in curing oven and is consolidated
Change, in this step, injection pressure is set as 0.1-0.2MPa, injection time 10min, and hardening time is set as 15H, solidification
Temperature setting is 150 DEG C
In parts pretreatment stage, a transition zone can also be uniformly smeared in vacuum extinction chamber surface, first along contact
Movement is longitudinal uniformly to smear entire arc-chutes, then is radially smeared along arc-chutes cambered surface, using such smearing mode so that transition
Layer is more uniform in the covering of vacuum extinction chamber surface, smears after completing, and dries in the air to transition zone and dries, and transition region thickness is set as
0.5mm smears transition zone so that vacuum interrupter and epoxy resin later can be engaged closely, buffer layer material
It is selected as natural rubber.
Simple using above-mentioned measure present invention process flow, the product insulation performance produced is outstanding, vacuum circuit breaker fortune
Dependable performance is stablized when row, and has very strong adaptability for rugged environment.'s
Description of the drawings：
Attached drawing 1 is the process flow chart of the present invention.
Specific implementation mode：
With reference to embodiment, the invention will be further described.It is the process flow diagram of the present invention referring to Fig. 1, Fig. 1,
It can be seen that from block diagram, the step of preparation process of pole of the invention includes：A, prepare mold, since mold is for life
The quality of the pole of production is extremely important, it is desirable that the good seal performance of mold, and cavity is highly polished, and convenient for demoulding,
It must be ranked sequentially according to lower core pulling, quiet mould, dynamic model, upper core pulling, ensure the positioning pin of dynamic model and quiet mould and lower core pulling
Positioning pin is in the center of location hole；It is closed dynamic model, quiet mould and upper core pulling, lower core pulling, mould pressurizing is given, makes mold
In packing state, setting die gap is less than 0.04mm；
B, parts pre-process：Vacuum interrupter, upper wire outlet seat, lower wire outlet seat are cleaned with alcohol, remove zero
The greasy dirt and dust on part surface；In this step, even closer in order to make vacuum interrupter and subsequent epoxy resin engage,
Vacuum extinction chamber surface uniformly smears a transition zone constituted with natural rubber, in order to ensure that the transition zone is smeared uniformly, needs
It is smeared according to the following steps：Longitudinal direction is moved along contact first and uniformly smear entire arc-chutes, then radially applied along arc-chutes cambered surface
It smears, is that transition zone is evenly distributed to vacuum extinction chamber surface using this smearing twice, dried in the air later to transition zone and dried, transition
Layer thickness is 0.5mm；
C, it preheats：Vacuum interrupter, upper wire outlet seat, lower wire outlet seat and some necessary Embedded Zero components are put into
Oven, setting heating time are 2.5H；
D, dispensing：Choose epoxy resin, curing agent, silica flour, toner mass ratio be 1:1:4:0.05, it successively will solidification
Agent, epoxy resin, silica flour, toner are put into vacuum pressure agitator tank, and the material after mixing is stirred evenly, and extract agitator tank and are
Vacuum state, and vacuum state 20min is kept, setting whipping temp is 70 DEG C, mixing time 1.5H.
E, it is injection moulded：By in epoxy resin injection to mold, 160 DEG C of temperature is kept, pressure remains 0.5MPa, keeps
Pole demoulds after 20-30min, and the pole after depanning is cleared up, is corrected, is then placed in curing oven and is consolidated
Change；Amendment for pole is to dispose the burr on its surface and impurity, ensures the finish on pole surface.
The above combination attached drawing is described above in detail the preferred embodiment of the present invention and embodiment, but the present invention is not
The above-described embodiment and examples are confined to, for those skilled in the art, are not departing from structure of the present invention
