Abstract
The utility model relates to a connection device of a plug-pull type cable terminal and a sleeve. The connection device is characterized by comprising a connecting sheet, a flange plate, and a lead cable of which two ends are respectively connected to the connecting sheet and the flange plate. The connection device has the advantages that the connecting sheet and the flange plate are respectively connected with the sleeve and the plug-pull type cable terminal; and because the connecting sheet and the flange plate are relatively smooth and burr-free, and the periphery of the flange plate does not have edge angles, requirements for current intensity and firm and tight connection are met, the aim of reducing partial discharge is fulfilled, the using safety and reliability of a transformer are improved, and installation and wiring of the transformer in certain special environments are facilitated.
Description
Technical field
The utility model relates to a kind of jockey, relates in particular to a kind of jockey that connects plug-in cable termination and sleeve pipe.
Background technology
Large oil immersed power transformer is one of capital equipment of electric power system, is the nucleus equipment of transformer station.In recent years, owing to receive Effect of Environmental, the transformer of novel line outgoing mode has appearred; No matter changed the outlet direction and the position of conventional transformer, also drawn a series of problem, be the partial discharge that the wedge angle burr is produced; Still angle, intensity and the connected mode to connecting portion all can exert an influence to transformer; The most influenced connected mode that is promptly is the junction between sleeve pipe and the plug-in cable termination, and this junction is relatively stricter for partial discharge and connection request; Partial discharge is in a single day excessive will to cause that the lead-in wire temperature rise is too high, insulation breakdown and short circuit.
Summary of the invention
The purpose of the utility model is to solve the problems referred to above of prior art existence and a kind of jockey that connects plug-in cable termination and sleeve pipe is provided; Through brace and ring flange respectively with sleeve pipe and plug-in cable termination; Reduce intensity and the tightness that connection is produced with this; Reach the purpose that reduces partial discharge, improved the transformer safety and reliability.
The above-mentioned technical purpose of the utility model mainly solves through following technical scheme: the jockey that connects plug-in cable termination and sleeve pipe; It is characterized in that comprising brace; Ring flange, and two ends are connected to the leader cable on brace and the ring flange.Through brace and ring flange respectively with sleeve pipe and plug-in cable termination; Reduce intensity and the tightness that connection is produced with this; Reached the purpose that reduces partial discharge, improved the transformer safety and reliability, made things convenient for installation and wiring because of transformer under some particular surroundings factors.And through facts have proved, used the jockey of connection plug-in cable termination that the utility model relates to and sleeve pipe after, greatly reduce the insulation fault that produces because of partial discharge.
As the further of technique scheme improved and replenish, the utility model adopts following technical measures:
The two ends of described leader cable are welded on respectively on brace and the ring flange.During use, brace is connected with sleeve pipe through connector, and ring flange is connected with ring flange on the plug-in cable termination through connector.Welding between leader cable and brace and the ring flange adopts brazing to connect.
Form the prominent head of connector on the ring flange surface for fear of the connector head, the connecting portion of described ring flange is uniformly distributed with a plurality of connection counterbores, and the prominent head of connector sinks to and connects in the counterbore.
For make between leader cable and the ring flange joint more firmly and contact area big, resistance and partial discharge when reducing electric current and flowing through, described ring flange middle part is provided with through hole, said leader cable inserts through hole and welds with ring flange.
Described ring flange is the red copper ring flange.
Described brace is the red copper brace.
Described brace is provided with at least two connecting holes.
The beneficial effect that the utlity model has: through brace and ring flange respectively with sleeve pipe and plug-in cable termination; Because brace and the smooth relatively no burr of ring flange and the no corner angle of ring flange periphery; Satisfy current strength and be connected firmly tight; Reached the purpose that reduces partial discharge, improved the transformer safety and reliability, made things convenient for installation and wiring because of transformer under some particular surroundings factors.

Embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technical scheme of the utility model.
Embodiment: connect the jockey of plug-in cable termination and sleeve pipe, as shown in Figure 1, it comprises brace 1, ring flange 2, and two ends are connected to the leader cable 3 on brace 1 and the ring flange 2.Brace 1 is provided with at least two connecting holes 5.Like Fig. 4-shown in Figure 5, during use, brace 1 is connected with sleeve pipe 8 on the transformer 7 through connector, and ring flange 2 is connected through the ring flange on the plug-in cable termination 9 on connector and the transformer 7.
The two ends of leader cable 3 adopt brazing to be connected on brace 1 and the ring flange 2 respectively.Adopt brazing to be connected to and be beneficial to resistance and the partial discharge that reduces weld.During welding, note the direction of firm welding and lug plate.
Shown in Fig. 2-3, the connecting portion of ring flange 2 is uniformly distributed with a plurality of connection counterbores 4, connects when using, and the connector head sinks to and connects in the counterbore, has avoided the connector head to form the prominent head of connector on the ring flange surface, also helps reducing partial discharge.
For make between leader cable and the ring flange joint more firmly and contact area big, resistance and partial discharge when reducing electric current and flowing through, ring flange 2 middle parts are provided with through hole 6, leader cable 3 insert through holes and with ring flange 2 welding.
In order further to reduce resistance and the partial discharge that this connects the jockey of plug-in cable termination and sleeve pipe, ring flange 2 is the thick red copper ring flange of 20mm, and brace 1 is the red copper brace.
