Abstract
A foil-type hollow reaction coil is made up by continuously winding metal foil. Several ventilation bars are supported between adjacent turns of foil to form a ventilation channel. An insulating belt able to be solidified is wound around the coil to form an external layer. The current packs are arranged at its start and end points in diagonal line mode. Its end frames are fixed to both ends where there are hollow anticorona devices. Its advantages are light weight, simple technology and low cost.
Description
The invention belongs to the High-Voltage Electrical Appliances field, be specifically related to a kind of foil style hollow inductive coil.
Existing hollow reactance coil generally adopts multiply aluminum steel or copper conductor parallel connection to be wound in the cartridge type coil, and all wire turns are arranged vertically.This coil has closed and open two classes.Closed coil adopts the tight spiral of insulation multiply hinge line to twine, pad insulation lattice framing between layer and the layer, and excircle is sealed glass fiber yarn or glass wool cloth, the manufacturing process complexity, to the insulating requirements height of multiply hinge line, overall dimension is big, and weight is big; Open coil then adopts plain conductor, but turn-to-turn and interlayer are embedded with cross-over block, and the cushion block of turn-to-turn will be determined its thickness through strict calculating, waste time and energy during making, and weight is still bigger.Superhigh pressure reactance coil in the past adopts corona ring or the solid anti-not-go-end frame tip of corona ball (rod) corona to occur in addition, has the shortcoming that the amount of labour is big and consume material is many.
The purpose of this invention is to provide a kind of in light weight, simple novel foil style hollow inductive coil of technology.
This foil style hollow inductive coil, comprise reactance coil 1, end frame 2,3, water conservancy diversion row 4,16, corona-proofing device 5, it is characterized in that reactance coil adopts metal forming to twine continuously, form air channels 10 by supporting some air channels bar 7 between each circle, twine insulating tape at the outermost layer of coil and form fiberglass encapsulated layer 6, water conservancy diversion row 4,16 is separately fixed on the diagonal of the initiating terminal of coil and terminating end, end frame 2,3 is fixed on the upper and lower side of coil, in the end of end frame corona-proofing device 5 is arranged.
Corona-proofing device 5 is hollow oval type corona rod, have square type slotted hole 11 at the cylindrical section of hollow oval type corona rod less than cylindrical section, hollow cylinder and two semicircle hollow balls are connected as a single entity, position one end corresponding with the slotted hole axis has hemisphere groove 12, one ends and has groove 13 on the semicircle hollow ball.
Corona-proofing device 5 is a hollow ellipse type corona rod, has square type slotted hole 11 at the interlude of hollow ellipse type corona rod, and position one end corresponding with square type slotted hole axis has hemisphere groove 12, one ends and have groove 13 on the semicircular hollow ball.
When the end frame is the metal material making, between end frame and coil, install cross-over block 8 additional, the upper and lower groove 14,15 that on cross-over block 8, has and end frame and air channel bar to cooperate.
When being to be used for the above electric power system of 220KV, the hollow corona rod of oval or ellipse radius of curvature is 20mm～50mm.
Advantages such as the present invention has in light weight, and production technology is simple, the requirement of suspension bracket intensity reduces greatly during to the trap on-line operation, also brings great convenience for transportation.Owing to adopt the hollow anticorona rod of expendable mo(u)ld moulding to replace solid corona rod and corona ring, can save material simultaneously, reduce cost, the special equipment of making corona ring has been saved in weight reduction, has simplified the manufacture craft of corona-proofing device.
