Abstract
A kind of bellows, including mounting plate, across the transmission shaft of mounting plate, the hole that bellows can be allowed to pass through is offered on a mounting board, stud is welded with around hole, bellows passes through mounting plate and is arranged on the outside of transmission shaft, the lower end of bellows and mounting flange weld, the upper end of bellows and bellows-welding flange welding, transmission shaft is together with bellows-welding flange welding, it is provided with mounting hole on mounting flange, a "O"-ring slot is provided on the upper surface of mounting flange, and be placed with " O " type sealing ring in the "O"-ring slot.The present invention is able to achieve in vacuum circuit breaker seal-moving connection between external agency and internal arc-chutes, meets the requirement of gas insulation switch cabinet.
Description
Technical field
The present invention relates to vacuum circuit breaker fields, relate in particular to a kind of bellows.
Background technique
Existing gas-filling cabinet is that one kind is filled with switchgear of the gas as dielectric inside it, this just has switchgear
The requirement of leakproofness.And vacuum circuit breaker is an important moving component on switchgear, does switching on and off movement in breaker
When, main axis can transfer energy to vacuum interrupter, and the vacuum interrupter as primary element is necessary in gas-filling cabinet
It is sealed in insulating gas, the breaker mechanism of front is placed on outside gas-filling cabinet, convenient for adjusting and safeguarding；This just needs one
Component with seal-moving function connects breaker mechanism part and vacuum interrupter, to realize entire switching on and off fortune
It is dynamic.And the seal-moving component in existing gas-filling cabinet mostly uses rubber seal greatly to realize rotary seal, there are easy agings
The shortcomings that.
Summary of the invention
It is able to achieve in vacuum circuit breaker between external agency and internal arc-chutes and seals the object of the present invention is to provide one kind
Move the vacuum circuit breaker bellows of connection.
Realizing the technical solution of above-mentioned purpose is: opening up on a mounting board including mounting plate across the transmission shaft of mounting plate
There is the hole that bellows can be allowed to pass through, stud is welded with around hole, bellows passes through mounting plate and is arranged on the outside of transmission shaft, ripple
The lower end of pipe and mounting flange weld, the upper end of bellows and bellows-welding flange welding, transmission shaft and bellows-welding method
Orchid welds together, and mounting hole is provided on mounting flange, is provided with a "O"-ring slot on the upper surface of mounting flange, and
" O " type sealing ring is placed in the "O"-ring slot.
After adopting the above technical scheme, the upper surface of mounting flange is leaned against on the mounting plate of breaker, on mounting flange
Mounting hole set stud on a mounting board on, by nut and tight, make the upper surface of mounting flange and mounting plate closely paste and,
Due to being provided with a "O"-ring slot on the upper surface of mounting flange, and it is placed with " O " type sealing ring in the "O"-ring slot, makes
It obtains and completely cuts off outside interior of the cabinet gas and cabinet body, and the upper end of bellows connects vacuum interrupter, the machine of lower end connection breaker
Structure part, to realize the seal-moving connection in vacuum circuit breaker between external agency and internal arc-chutes.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
The invention will now be described in further detail with reference to the accompanying drawings.
As shown in Figure 1, the present invention includes mounting plate 4, across the transmission shaft 1 of mounting plate 4, energy is offered on mounting plate 4
It allows the hole that bellows passes through, stud 7 is welded with around hole, bellows 3 passes through mounting plate 4 and is arranged on the outside of transmission shaft, ripple
The lower end of pipe 3 and mounting flange 6 weld, and the upper end of bellows 3 and bellows-welding flange 2 weld, and transmission shaft 1 and bellows weld
Acting flange 2 welds together, and mounting hole is provided on mounting flange 6, and a "O"-ring is provided on the upper surface of mounting flange 6
Slot, and " O " type sealing ring 5 is placed in the "O"-ring slot.
It is provided with the hole that bellows can be allowed to pass through on the mounting plate 4 of breaker, is welded with stud 7 around hole, when installation,
The mounting plate 4 that bellows is passed through to breaker, the mounting hole on mounting flange 6 is covered on stud 7, then by mounting flange 6
There is the side of " O " type sealing ring 5 to lean against on breaker mounting plate 4, with nut and tight.Thereby realize the fortune inside gas-filling cabinet
The connection of dynamic component and gas-filling cabinet external moving part has reached the requirement of gas insulation switch cabinet.
