Description
Technical field
The present invention relates to a kind of insulated tube bus, the jockey between especially a kind of single insulated tube bus belongs to the transmission equipment accessory technical field.
Background technology
Along with the increasing of transforming plant main transformer capacity, transformer 10kV and 35kV side bus rated current have surpassed 3000A, conventional rectangular bus bar big loop of incompatibility operating current on technology and structure.When the separate unit main transformer capacity reaches 180MVA when above; Because the shared proportion of rated current, short circuit current and the separate unit main transformer capacity of step down side increases, main transformer low pressure outlet side not only has the electric power problem of bus bridge own, heating problem, also has the reinforcing bar heating problem that inductive loop causes in alternating intense magnetic field near the concrete column of bus bridge post insulator, steel framework and bus bridge, the basis.Advantages such as the insulated tube bus is as the substitute of rectangular bus bar, and is big with its ampacity, that mechanical strength is high, thermal diffusivity is good are adopted by increasing power plant, substation gradually.The length of single insulated tube bus is 6-8m, need connect into long insulated tube bus through middle jockey, to satisfy instructions for use.Existing insulated tube bus adopts the middle jockey of outer hood type, and transition joint is partly much thick than the insulated tube bus that is connected, and cost is high, and insulating barrier is difficult to be made, and influences the bus outward appearance; And outer hood type causes partial discharge quantity bigger because of the protruding tip part is unavoidably arranged, and has shortened the useful life of insulated tube bus greatly.
Chinese invention patent (CN20112588) discloses a kind of " composite type insulated tube bus intermediate connector "; There is quiet conductive head on the middle transition moving conductive head both sides of this intermediate connector; Cooperate with middle transition moving conductive head through fastening transmission key with the fastening screw mandrel of positive and negative rectangle screw thread that quiet conductive head links together, middle transition moving conductive head inner conical conductive contact surfaces closely contacts with quiet conductive head conical contact face.During use; The non-taper surface one end welding of insulated tube bus end and quiet conductive head; The fastening screw mandrel of forward and reverse rectangle screw thread is with middle transition moving conductive head, quiet conductive head firm locking, and the outside is fixed with prefabricated protected type shrinkage insulating case, forms the intermediate connector of bulk shielding insulation.Advantages such as this intermediate connector has the compactness of being connected firmly, and contact area is big, and electric conductivity is strong, and tensile strength is big, and connected two sections insulated tube bus smooth-shapeds are smooth, and insulation property are strong, and the moistureproof and waterproof ability is strong.But connected two sections insulated tube bus ends all need be welded with the first end of quiet conduction, influence site operation speed, have strengthened construction cost.The fastening screw mandrel of positive and negative rectangle screw thread is housed in the middle transition moving conductive head; And connect through key, the fastening screw mandrel of positive and negative rectangle screw thread again with the quiet conductive head at two ends through positive and negative rectangle screwed connection, complex structure; The part kind is many; And, influence the electric conductivity of connected two sections insulated tube buses because the influence in rectangle screw thread gap causes the bellmouth of middle transition moving conductive head can't be connected very closely with quiet conductive head conical head.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, low cost of manufacture, can improve the reliability that the insulated tube bus connects, and simplify step of connecting in the middle of the site operation, improve jockey in the middle of the insulated tube bus of installation effectiveness.
The present invention is achieved through following technical scheme:
Jockey in the middle of a kind of insulated tube bus; Comprise bus transition joint, nut positioning groove plate, holding screw, nut, joint drift; Said bus transition joint is the pipe fitting that the middle part is provided with radial flange, and said pipe fitting two ends are set in two sections insulated tube buses, and said radial flange external diameter equates with the insulated tube bus external diameter that is connected; Radial flange is provided with the radial hole that penetrates bus transition joint tube wall, and the tube wall of said radial hole offside is opened axial wedge-shaped slot; Nut is arranged in the nut positioning groove plate, and said nut location notch is positioned at the radial hole downside; Said holding screw passes radial hole and is screwed into nut, and the holding screw lower end is pressed in joint drift upside, and joint drift downside is clamp-oned in the axial wedge-shaped slot of bus transition joint.
The object of the invention can also further realize through following technical measures.
Jockey in the middle of the aforesaid insulated tube bus, the gradient of wherein said joint drift and wedge-shaped slot is 1:4～1:5.
The present invention is simple in structure, number of parts is few, low cost of manufacture, installation are quick and convenient; Promote the axial wedge-shaped slot that joint is carved the transition joint of iron extruding bus through holding screw; 1:4～1:5 gradient that joint drift and wedge-shaped slot equate can be locked in the axial wedge-shaped slot of bus transition joint the joint drift, utilizes the huge extruding force of joint drift two inclined-planes to the axial wedge-shaped slot of bus transition joint; The bus transition joint pipe fitting that two ends are sleeved in two sections isolated buses is squeezed back external diameter change greatly; Tightly fit with insulated tube bus inwall, and keep excellent contact, thereby have conductivity preferably.Two sections isolated buses connect smoothly, and the no ledge in surface is convenient to make insulation, has guaranteed the safe operation of isolated bus.
Advantage of the present invention and characteristics will illustrate through the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide with reference to accompanying drawing as an example.
