Description
Technical field
A kind of isolated-phase enclosed bus bellows of the utility model, the machine circuit that is related to generating electricity are flexible coupling technical field.
Background technology
Generator outlet isolated-phase enclosed bus and generator, excitation-transformation variable, factory's height change etc. are using its shell of position being flexible coupling
It is both needed to be flexible coupling using bellows, is currently mainly used soft rubber bellows, function is that prevent inner conductor to be flexible coupling directly naked
Dew, while can have certain compensation surplus in bus temperature variation, unit vibration.
For existing soft rubber bellows as shown in Fig. 1 of Figure of description, label 11 is metal anchor ear in Fig. 1, uses screw rod
Locking；Label 12 is soft rubber bellows, and typically the both ends of soft rubber bellows are set to outside the metal of isolated-phase enclosed bus
On shell, then metal anchor ear is locked.
Since soft rubber is easy to aging, deformation, in addition the vibrations generated when unit operation and bellows itself expand with heat and contract with cold,
In During Process of Long-term Operation, bellows will produce crackle, breakage and displacement, also be easy to cause bellows both sides clip and loosens, exists
Clip is fallen into the risk for causing short circuit, earth fault in busbar.Once the generator one caused by metal anchor ear loosens occurred
The case where point ground connection.And after bellows aging, envelope mother need to be flexible coupling dismounting when replacement, workload is larger, constructs extremely
It is inconvenient.In addition, most of rubber sulfur-bearing itself, the sulfide that is discharged in ageing process easily with the female conductor of envelope and the surface plating that is flexible coupling
Silver layer chemically reacts, and forms silver sulfide, causes silver coating blackening, influence its electric conductivity.
Invention content
In order to solve the above technical problems, the utility model provides a kind of isolated-phase enclosed bus bellows, using two
Semi-circular features connection it is assembled, have the characteristics that it is convenient for disassembly and assembly simply, reliability it is high；Using the utility model bellows, no
It is only capable of saving time cost, while equipment operation risk can also be reduced, there is preferable reliability and economic benefit.
The technical solution that the utility model is taken is：
A kind of isolated-phase enclosed bus bellows, including ripple tube body, flange assembly, the ripple tube body, flange group
Part is two semicircular structures, and flange assembly is locked at by bolt assembling on enclosed busbar shell, two semicircular structures
Ripple tube body and flange assembly fasten, an entirety is connected as by axis pin.
The ripple tube body, flange assembly are all made of MC/PTFE polymer composites and are made.
The flange assembly is lined with sealing strip.
The ripple tube body includes point half bellows of two semicircular structures.
The flange assembly include be arranged bellows body upper part loose flange, set consolidating in bellows body lower part
Determine flange, the loose flange, the semi-circular flange unit that mounting flange is symmetrical by two, diameter is consistent are constituted.
Each semi-circular flange unit has been fixedly connected with free bearing, and loose flange is arranged with two and carries arc-shaped concave
The first free bearing, mounting flange be arranged with two carry arc-shaped concave the second free bearings.Along the lug boss of ripple tube body
Point, multiple third free bearings with arc groove are equipped with, axis pin from top to bottom sequentially passes through：First free bearing, multiple thirds hinge
Seat, the second free bearing fix ripple tube body.
A kind of isolated-phase enclosed bus bellows of the utility model, has the following advantages：
1, sealing strip is housed, to increase the friction between enclosed busbar shell, bellows in the bellows flange assembly
Ontology is buckled in the card slot of flange assembly, and an entirety is connected as by axis pin.Simultaneously because MC/PTFE materials are preferably strong
Degree, even if the loose flange at both ends, mounting flange lock portion loosen the risk that there will not be and fall off because of temperature, vibration.
2, MC/PTFE materials have that density is small, water absorption rate is low, anti-aging property is good, good insulation and flame retardant property, right
Strong acid, highly basic, strong oxidizer have very high corrosion stability, non-aging decomposition not to have any influence to the female conductor silvering of envelope；
3, the bellows is formed by connecting by two semicircular structures, has the characteristics that demolition, installation are convenient and simple.
4, because bellows is flexible coupling place shell position using more in isolated-phase enclosed bus, the utility model ripple is used
Pipe, can not only save time cost, while can also reduce equipment operation risk, have preferable reliability and economic benefit.

Specific implementation mode
As shown in Fig. 1 ~ Fig. 4, a kind of isolated-phase enclosed bus bellows, including ripple tube body, flange assembly.
The ripple tube body, flange assembly are two semicircular structures, and flange assembly is locked at by bolt assembling
On enclosed busbar shell 7, ripple tube body and the flange assembly of two semicircular structures fasten, and one is connected as by axis pin 4
It is whole.Axis pin 4 uses split pin.
The ripple tube body, flange assembly are all made of MC/PTFE polymer composites and are made.
The flange assembly is lined with sealing strip.
The ripple tube body includes point half bellows 3 of two semicircular structures.
The flange assembly include be arranged bellows body upper part loose flange 1, set in bellows body lower part
