Description
Technical field
The utility model relates to high voltage bus, specifically a kind of sealing device for high voltage bus.
Background technology
Along with the fast development of China's economy, the demand of entire society to electric power increases day by day, high voltage bus is large with ampacity, good insulation preformance, mechanical strength are high, good heat dissipation, temperature rise is low, loss is low, be widely used gradually etc. advantage, but there is poor sealing to the sealing device of high voltage bus Systematical control, easily leak air long-time useful life phenomenon, causes equipment part short for useful life, increase cost, the problems such as inefficiency.
Utility model content
Technical problem to be solved in the utility model is, for the shortcoming of above prior art, proposes a kind of sealing device for high voltage bus, this is used for the sealing device of high voltage bus, and not only structure is simple, easy to operate, structure is simple, reduces originally low, long service life, versatility is high, and volume is little, easy accessibility, operating efficiency is provided, increases stability and the reliability of equipment.
In order to solve the problems of the technologies described above, the technical solution of the utility model is achieved in the following ways: a kind of sealing device for high voltage bus, comprise base, base is provided with the first case and the second case along its length successively, connecting rod is provided with between first case and the second case, sealing rubber cover is arranged with at the two ends of connecting rod, sealing rubber cover one end circumferencial direction is at least provided with a ring annular groove, on the inner side of the first case and the second case opposite face, equal fold inward goes out annulus, at least one circle annular boss is provided with at annulus endoporus circumferencial direction, annular boss and annular groove interference fit.
Like this, by arranging the annular groove and annular boss interference fit that caulking gum puts, make whole case airtight, good seal performance, owing to using the material of rubber, crocking resistance is good, energy Reusability, long service life, and adopt and multiple groove is set coordinates with boss, strengthen sealing effectiveness, ensure that the reliability of sealing, also air, water and dust can be avoided to enter in case simultaneously, increase the useful life of part, reduce costs.
The technical scheme that the utility model limits further is:
The aforesaid sealing device for high voltage bus, annular groove and annular boss are trapezoidal shape, arrange the effective length that trapezoidal shape can increase sealing, and adopt chamfered fit to facilitate plug, improve the operating efficiency of staff, simple and practical.
The aforesaid sealing device for high voltage bus, the quantity of annular groove and annular boss is three.
The aforesaid sealing device for high voltage bus, connecting rod is red copper bar, adopts red copper bar, reduces the loss of electric energy, and works long hours, there will not be the phenomenons such as oxidation.
The aforesaid sealing device for high voltage bus; the second annular boss is provided with in the inner side of the first case and the second case opposite face; the end face of sealing rubber cover is also provided with the annular groove matched with the second annular boss; end face is also provided with hermetically-sealed construction; play double protection; add the sealing effectiveness of this equipment, guarantee the foreign matter isolating such as equipment and extraneous air from, increase the safety and reliability of equipment.
The beneficial effects of the utility model are: by arranging the annular groove and annular boss interference fit that caulking gum puts, make whole case airtight, good seal performance, owing to using the material of rubber, crocking resistance is good, energy Reusability, long service life, and employing arranges multiple groove and coordinates with boss, strengthen sealing effectiveness, ensure that the reliability of sealing, air, water and dust also can be avoided to enter in case simultaneously, increase the useful life of part, reduce costs; First case and the second case end face are also provided with hermetically-sealed construction, play double protection, add the sealing effectiveness of this equipment, guarantee the foreign matter isolating such as equipment and extraneous air from, increase the safety and reliability of equipment.
