Outdoor high-voltage alternating current breaker has very product quality and service life due to being in outdoor environmental work, weather for a long time
The cataclysm of big influence, temperature can cause enclosure interior to generate condensation, and operating mechanism is made to gradually appear rusty stain, and then influence to use
Function, even results in failure, and the cost of field maintenance is very high.
Part common box type outdoor high-voltage alternating current breaker mostly uses the mode for filling SF6 gases, not only plays insulating effect, but also right
Operating mechanism accomplishes effective protection, but SF6 is a kind of greenhouse gases, will be prohibited to make after requiring many decades according to the Kyoto Protocol
With.Column support type outdoor high-voltage alternating current breaker is although reasonable for structure, and insulation is reliable, and production cost is low, but degree of protection stops always
The level of IP65 is stayed in, even if individual manufacturers are claimed to be IP67, practical effect is unsatisfactory, caused by condensation
Operating mechanism key component corrosion, makes the event of mechanism akinesia happen occasionally.
Invention content
In place of the purpose of this utility model is to overcome above-mentioned deficiency, to provide a kind of no-welding sealing structure, into one
Step improves the sealing effect of case for circuit breaker, realizes the environmental protection to enclosure interior parts, makes to use the technology with this
Breaker reach high reliability.
According to technical solution provided by the utility model, a kind of no-welding sealing structure includes Shell of circuit breaker, sealing ring
And top sealing plate, it is characterized in that：Shell of circuit breaker upper end inside edge is equipped with the sealed groove of U-shaped structure, is embedded in sealed groove
Sealing ring；Shell of circuit breaker upper end is equipped with top sealing plate, and top sealing plate will be sealed by multiple connection Shell of circuit breaker that hold down assembly
Circle is pressed in sealed groove；The sealing ring is equipped with o-ring groove towards sealed groove end face center, sealed groove and disconnected
Road device shell is integrally formed.
Further, it holds down assembly including top board, hold-down bolt, lower platen and locking nut, top board is welded on top
On sealing plate, lower platen is welded on Shell of circuit breaker, and hold-down bolt sequentially passes through lower platen and top board and passes through from the bottom up
It is threadedly coupled hold-down bolt.
Further, multiple hold down assembly is uniformly distributed along the top sealing plate left and right sides.
Further, top sealing plate lower end is equipped with sealing plate flanging.
Further, adjacent seals groove junction is equipped with notch.
Compared with the prior art the utility model has the following advantages：
The utility model is simple in structure, compact, reasonable, and sealing circle center is equipped with o-ring groove, and o-ring groove is set
Set surrounding of the pressing force peptizaiton in o-ring groove that can be allowed and act on sealing ring so that the pressing force effect of being evenly distributed
On sealed groove end face, avoid because being damaged caused by the effect of pressing force concentration；The setting of sealing plate flanging make top sealing plate and
It is more preferable that sealing performance is contacted between sealing ring；Sealed groove and Shell of circuit breaker use the same board making, improve entirety
Structural strength and sealing performance, while manufacture craft is also more convenient.
