Abstract
The utility model relates to a thermal -insulated protector of transposed conductor paper bag equipment belongs to transformer transposed conductor production technical field. Technical scheme is: thermal -insulated protecting tube (8) install at hollow shaft (6) insidely through spring leaf (7), transposed conductor (5) are passed at the center of thermal -insulated protecting tube (8), spring leaf (7) quantity is a plurality of, and the one end of every spring leaf is fixed in the hollow shaft, and the other end is fixed on thermal -insulated protecting tube, and transmission shaft (4), hollow shaft and thermal -insulated protecting tube are arranged with one heart. Transposed conductor passes through in thermal -insulated protecting tube, has avoided paper bag head equipment to cause the influence of the temperature rise of self to transposed conductor because of rotating etc. Under the radiating condition of the equipment that does not influence, both reached thermal -insulated purpose, solved the influence of paper bag head hollow shaft dust to product quality again, avoided softening again of in transposed conductor production process self -adhesion lacquer layer, effectively solved this difficult problem of the local adhesion of transposed conductor, improved product quality greatly.
Description
Technical field
The utility model relates to a kind of heat-insulating protective device of transposed conductor paper bag equipment, belongs to transposed conductor of transformer production technical field.
Background technology
Transposed conductor insulate after enameled sheet wires replace on request by many self-adhesions, with electrician's insulating paper strip multilayer continuously, closely wrapped after winding wire.Along with the continuous increase of power transformer individual capacity, the electric current of low pressure winding also increases thereupon, and therefore the transposed conductor of larger cross-section is also more and more applied.Transposed conductor is in wrapped process, paper bag head produces heat in continuous print operation process, the in particular cases bearing pedestal temperature rise at paper bag head two ends may reach 70-80 DEG C, and background technology produces transposed conductor self-adhesion paint used, will occur to soften again when about 110 DEG C under stress-free condition through test, the self-adhesion paint existed under wrapped pressure softens again, and temperature can obviously reduce.In the wrapped process of transposed conductor, wire by hollow shaft time without provision for thermal insulation, because of guidewire movement speed in normal productive process, wire is influenced by heat not obvious, but when paper is changed in parking, the wire time of staying is longer, the outer field self-adhesion enamelled coating of transposed conductor is easily caused to soften, make to occur adhesion phenomenon between adjacent wires, have a strong impact on properties of product.In actual applications, often occur that wire hardens in high-power transformer coil-winding process, coiling is not smooth, disassembles between the wire of rear discovery local and there is irregular self-adhesion paint adhesion phenomenon, have a strong impact on the quality of product.
Utility model content
The utility model object is to provide a kind of heat-insulating protective device of transposed conductor paper bag equipment, by installing heat-insulating protective device additional, when not affecting equipment cooling, both heat insulation object had been reached, solve again paper bag head hollow shaft dust to the impact of product quality, effectively prevent this difficult problem of transposed conductor focal adhesion, substantially increase product quality, solve the problems referred to above that background technology exists.
The technical solution of the utility model is: a kind of heat-insulating protective device of transposed conductor paper bag equipment, comprise needle bearing, bracing frame, bearing, power transmission shaft, transposed conductor, hollow shaft, spring leaf and heat insulation protecting tube, hollow shaft is fixedly mounted in power transmission shaft by needle bearing and bracing frame, heat insulation protecting tube is arranged on hollow shaft inside by spring leaf, and transposed conductor passes at the center of heat insulation protecting tube; Described spring leaf quantity is multiple, and one end of each spring leaf is fixed in hollow shaft, and the other end is fixed on heat insulation protecting tube, power transmission shaft, hollow shaft and heat insulation protecting tube arranged concentric.
Described spring leaf quantity is three, and spaced 120 degree are arranged in the gap between hollow shaft and heat insulation protecting tube.
Described power transmission shaft, is arranged on bearing by bearing and bearing pedestal.
Described heat insulation protecting tube is the tubular body adopting heat-barrier material to make.
During use, transposed conductor passes through in heat insulation protecting tube, supported by spring leaf between heat insulation protecting tube and hollow shaft, transposed conductor paper bag equipment is dispelled the heat by gap between heat insulation protecting tube and hollow shaft, heat insulation protecting tube carries out heat insulation protection to transposed conductor, meanwhile, avoid paper bag head hollow shaft dust on the impact of product quality.
Good effect of the present utility model: the utility model by installing the heat insulation protecting tube be made up of heat-barrier material additional in the hollow shaft that transposed conductor passes through, during use, wire passes through in heat insulation protecting tube, avoids paper bag head apparatus and causes self the impact of temperature rise on transposed conductor because to rotate etc.; Simultaneously for not affect equipment cooling, between heat insulation protecting tube and hollow shaft, adopt spring leaf to support, when not affecting equipment cooling, both heat insulation object had been reached, solve again paper bag head hollow shaft dust to the impact of product quality, avoid softening again of self-adhesion enamelled coating in transposed conductor production process, efficiently solve this difficult problem of transposed conductor focal adhesion, substantially increase product quality.
