Abstract
The utility model provides a from looks enclosed bus connecting piece, includes two semicircular PI panels, and two semicircular PI panel upper portions, lower parts are all connected aluminium through coupling nut and are closed the tight mechanism of golden lock, and each aluminium closes the tight mechanism of golden lock and includes two semicircular staple bolts, and two semicircular staple bolts pass through locking screw and connect fixedly. All be provided with the screw on semicircular staple bolt, the semicircular PI panel, the screw is waist shape hole. The utility model relates to a from looks enclosed bus connecting piece can not only practice thrift working hour cost, can also move the risk by reduction equipment simultaneously, has better reliability and economic benefits.
Description
Technical field
The utility model relates to a kind of bellows, particularly a kind of isolated-phase enclosed bus connector.
Background technology
Generator outlet isolated-phase enclosed bus and generator, excitation become, factory's height to become etc. and adopts its shell of position be flexible coupling all to need to adopt bellows to be flexible coupling.At present mainly use soft rubber bellows, function is that to prevent inner conductor to be flexible coupling directly exposed, can have certain compensation surplus when bus temperature change, unit vibration simultaneously.
Existing soft rubber bellows as shown in Fig. 1 of Figure of description, wherein: 6 is metal anchor ear, and metal anchor ear is locked by screw rod; 7 is soft rubber bellows, is normally set on the metal shell of isolated-phase enclosed bus by the two ends of soft rubber bellows 7, is then locked by metal anchor ear 6.
Due to soft rubber easily aging, distortion, expanding with heat and contract with cold of the vibrations produced when adding unit operation and bellows self, in During Process of Long-term Operation, bellows can crack, damaged and displacement, also easily cause bellows both sides clip to get loose, clip drops the risk entering and can cause short circuit, earth fault in bus.Once occurred to cause the situation of generator one point earth because metal anchor ear gets loose.And after bellows is aging, need be flexible coupling envelope mother during replacing dismounting, and workload is comparatively large, and construction is inconvenience very; In addition, the sulfur-bearing of most of rubber own, the sulfide discharged in ageing process is easy and seal female conductor and the plated surface silver layer generation chemical reaction that is flexible coupling, and forms silver sulfide, causes silver coating blackening, affect its electric conductivity.
Summary of the invention
Easily aging and discharge sulfide for solving rubber described in background technology; Soft rubber bellows is changed, dismounting inconvenience; Soft rubber bellows because of temperature disturbance reason cause anchor ear to loosen after easily cause the problem of bus one point earth.The utility model provides a kind of isolated-phase enclosed bus connector, can not only save time cost, can also reduce equipment operation risk simultaneously, have good reliability and economic benefit.
The technical scheme that the utility model adopts is:
A kind of isolated-phase enclosed bus connector, comprise two semicircular PI sheet materials, two semicircular PI sheet material top, bottom are all by attaching nut's connecting aluminum alloy retaining mechanism, each aluminium alloy retaining mechanism comprises two semicircular anchor ears, and two semicircular anchor ears are connected and fixed by tie down screw.Described semicircular anchor ear, semicircular PI sheet material are provided with screw, and described screw is mounting hole.
The stitching portion of described two semicircular PI sheet materials is provided with sealing strip.
Two semicircular anchor ear internal layers of described aluminium alloy retaining mechanism are provided with sealing strip.
A kind of isolated-phase enclosed bus connector of the utility model, technique effect is as follows:
1), semicircular anchor ear, semicircular PI sheet material are provided with mounting hole, are used for compensating upper and lower end and seal the eccentric phenomena that female shell may exist.
2), two semicircular PI sheet materials stitching portion is provided with sealing strip, two semicircular anchor ear internal layers are provided with sealing strip, to increase the friction between enclosed busbar shell; Simultaneously due to the good supportive of PI sheet material, even if the aluminium alloy retaining mechanism at its two ends loosens because of temperature disturbance, do not have the risk come off yet.
3), PI panel density is little, has very high corrosion stability, not easily degradation and decomposition to strong acid, highly basic, strong oxidizer, can not have any impact to the female conductor silvering of envelope.
4), this connector entirety is formed by connecting by two semicircle anchor ears, semicircular PI sheet material, has the simple feature of easy accessibility.
Accompanying drawing explanation
Fig. 1 is the soft rubber bellows structure schematic diagram described in background technology.
Fig. 2 is a kind of isolated-phase enclosed bus connecting-piece structure of the utility model schematic diagram.
Embodiment
As shown in Figure 2, a kind of isolated-phase enclosed bus connector, the stitching portion comprising two semicircular PI sheet material, 4, two semicircular PI sheet materials 4 is provided with sealing strip.Two semicircular PI sheet materials 4 are spliced into the bellows entirety of tubulose, and the overall top of described bellows, bottom are provided with the first outstanding connection edge 5.
Each aluminium alloy retaining mechanism 2 comprises two semicircular anchor ears, and two semicircular anchor ear internal layers are provided with sealing strip.Be positioned at two semicircular anchor ears on the overall top of described bellows, be connected and fixed by the tie down screw 1 being arranged on two semicircle anchor ear sides.Be positioned at two semicircular anchor ears of the overall bottom of described bellows, be connected and fixed by the tie down screw being arranged on these two semicircle anchor ear sides.
The upper and lower part of each aluminium alloy retaining mechanism 2 is provided with the second outstanding connection edge 5 '.
Described first connection edge 5 ', connection edge 5, second is provided with multiple screw, described multiple screw is mounting hole, each aluminium alloy retaining mechanism 2, through the screw be arranged on the first connection edge 5 ', connection edge 5, second, is fixed with described bellows integrated connection by attaching nut 3 correspondence.
Claims (3)
1. an isolated-phase enclosed bus connector, comprise two semicircular PI sheet materials (4), it is characterized in that, two semicircular PI sheet material (4) top, bottom are all by attaching nut (3) connecting aluminum alloy retaining mechanism (2), each aluminium alloy retaining mechanism (2) comprises two semicircular anchor ears, and two semicircular anchor ears are connected and fixed by tie down screw (1);
