Abstract
A clamping type lead large-current rectifier transformer comprises a transformer body and a junction copper bar, wherein the junction copper bar is of a double-layer copper bar, punches are arranged on the copper bar correspondingly, a fastening bolt is arranged on each punch, and a double-cake outgoing wire led out from a low-tension coil is led out between the double-layer junction copper bars according to corresponding arrangement and is directly clamped and fixed by the fastening bolts; and one end of the junction led-out soft connection is clamped between the double-layer junction copper bars and is directly clamped and fixed by the fastening bolts. The fastening bolts adopt copper bolts or stainless steel bolts. For the clamping type lead large-current rectifier transformer, lead heads which are scrapped cleanly are inserted in the double-layer junction copper bars in sequence when a lead is in installation and then the fastening bolts are fastened, so that welding materials and energy resources can be saved, and the working time can be shortened; no welding exists during the lead installation and production processes, no heat and carbide is produced, the hidden hazard of burning the coil is avoided, and the transformer body is clean and attractive; and no environmental pollution is caused so as to be beneficial to environment friendliness and health of operators.
Description
Technical field
The utility model relates to a kind of rectifier transformer, the big current commutates transformer of particularly a kind of clipping lead-in wire.
Background technology
The low-voltage lead technology of the big current commutates transformer of tradition is two cakes that low-voltage coil is drawn to be lifted one's head line utilize oxygen welding technology or resistance-welding process that the end of a thread directly is welded on the confluence copper bar according to corresponding arrangement with the phosphor-copper welding rod to draw.The following deficiency that the rectifier transformer of this kind connected mode exists:
Have naked light to produce during 1, owing to welding, the heat of generation is big, can burn out coil because of carelessness;
2, because the high temperature of welding makes the confluence copper bar appearance surfaces that oxidative phenomena be arranged, not attractive in appearance; And, pollute the device body easily at welding process generation carbide, whole device body insulation or oil insulation are had a negative impact;
3, welding is generally adopted gas welding, is wasted energy and welding material, wastes man-hour.
Summary of the invention
The purpose of this utility model is to provide a kind of big current commutates transformer of clipping lead-in wire that does not have welding process when lead-in wire is installed, to overcome the existing above-mentioned deficiency of prior art.
The technical scheme that the utility model is taked is: the big current commutates transformer of a kind of clipping lead-in wire, comprise low-voltage coil and confluence copper bar, described confluence copper bar is double-deck confluence copper bar, have punching successively according to corresponding arrangement on the double-deck confluence copper bar, be installed with fastening bolt in each punching, two cakes that low-voltage coil is drawn are lifted one's head line and are drawn successively in being fixedly clamped by fastening bolt between two copper bars about double-deck confluence copper bar according to corresponding arrangement.
Its further technical scheme is: the described end of drawing copper strips that confluxes is fixedly clamped on double-deck confluence copper bar by fastening bolt.
Described fastening bolt adopts brass bolt or stainless steel bolt.
Owing to take above technical scheme, the big current commutates transformer of a kind of clipping lead-in wire of the utility model has following beneficial effect:
1, because the clipping lead-in wire of the big current commutates transformer adopting of a kind of clipping lead-in wire of the utility model, two cakes that low-voltage coil is drawn are lifted one's head line and are directly drawn with the bolted clamping with confluence copper bar according to corresponding arrangement, no welding process, do not produce heat, carbides-free produces, avoid the burning hidden danger of coil, and device body cleaning is attractive in appearance;
2, the big current commutates transformer of a kind of clipping lead-in wire of the utility model only needs to scrape clean the end of a thread and injects successively between the double-deck copper bar when lead-in wire is installed, and tightens fastening bolt then and gets final product, and has both saved the welding material and the energy, shortens man-hour again;
3, the big current commutates transformer of a kind of clipping lead-in wire of the utility model environmentally safe in the production process that lead-in wire is installed, environmental and operating personnel's health.
Be further described below in conjunction with the technical characterictic of drawings and Examples the big current commutates transformer of a kind of clipping lead-in wire of the utility model.
