Abstract
The utility model discloses a fixing structure for a low-voltage lead of an oil-immersed distribution transformer. A core and a clamp are arranged in an oil tank of the transformer, wherein a coil is sleeved on the core; a low-voltage bushing is fixedly supported on transformer box cover; three holes are punched in an upper low-voltage clamp; a 4mm-thick 3240 epoxy glass cloth plate is screwed on the upper low-voltage clamp through the three holes by bolts; four slotted holes are punched in the glass cloth plate; low-voltage lead connecting pieces of each phase penetrate through the four slotted holes, the upper ends of the low-voltage lead connecting pieces are connected to low-voltage conducting rods to lead a circuit out of the oil tank, and the lower ends of the low-voltage lead connecting pieces are connected with the coil through low-voltage lead copper bars; low-voltage porcelain insulators are sleeved outside the low-voltage conducting rods. According to the fixing structure, the use of a wood lead clamping plate for clamping the low-voltage lead is avoided, so that raw materials are saved, and the production cost of a product is lowered; the fixing structure is simple and convenient and easy to operate, and can be smoothly operated by a worker, so that the production efficiency is improved.
Description
Technical field
The utility model belongs to field transformer, relates to a kind of fixed structure of oil immersion-type distribution transformer low-voltage lead.
Background technology
Present stage, the low-voltage lead of oil immersion-type distribution transformer is all with wooden clamp plate holder, this structure workman is pretty troublesome while working, with clamp, must on low pressure upper clamping piece, weld two down-lead brackets, be used for fixing wooden cable guide, increased welding sequence, operation is many, time-consuming, effort, production efficiency is low, increased the solder joint of low pressure upper clamping piece, affect transformer semi-finished product presentation quality, make product seem very not attractive in appearance, use wooden folder folder lead-in wire, multiplex two down-lead bracket accessories and wooden cable guide, waste raw material, increase production cost.
Summary of the invention
The utility model is in order to make up the deficiencies in the prior art, and a kind of fixed structure of oil immersion-type distribution transformer low-voltage lead of simple in structure, easy for installation, the material that avoids waste is provided.
The utility model is achieved by the following technical solution:
The fixed structure of oil immersion-type distribution transformer low-voltage lead of the present utility model, iron core and folder are housed in oil tank of transformer, on iron core, overlapping coil, transformer box cover upper support is fixed with low-tension bushing, it is characterized in that: on low pressure upper clamping piece, make a call to three holes, by these three holes, 3240 thick epoxy resin bonded fibers of 4mm are screwed on low pressure upper clamping piece with bolt, on glass-cloth board, make a call to four slotted holes, the low-voltage lead brace of each phase is connected on low voltage conductive bar through these four slotted holes and upper end, circuit is drawn to fuel tank, the lower end of low-voltage lead brace is through low-voltage lead copper bar connecting coil, low voltage conductive bar overcoat has low pressure porcelain vase.
The beneficial effects of the utility model are, 1. do not use wooden clamp plate holder low-voltage lead, have saved raw material, have reduced the production cost of product; 2. simple in structure, easy to operate, workman while working very smoothly, has therefore improved production efficiency; 3. not be used in welding lead support on low pressure upper clamping piece, therefore do not need polishing welding seams, transformer semi-finished product presentation quality increases, not only save material but also enhance productivity, reduced welding sequence, workman works conveniently, solder joint is reduced, increased the aesthetics of product.
Accompanying drawing explanation

In figure: 1, wooden clamp, 2, low pressure porcelain vase, 3, low-voltage lead brace, 4, transformer box cover, 5, coil, 6, low pressure upper clamping piece, 7, low-voltage lead bronze medal, 8, down-lead bracket, 9, solder joint, 10, low voltage conductive bar, 11,3240 epoxy resin bonded fibers.
Embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.
The fixed structure of oil immersion-type distribution transformer low-voltage lead of the present utility model, iron core and folder are housed in oil tank of transformer, on iron core, overlapping coil 5, transformer box cover 4 upper supports are fixed with low-tension bushing, on low pressure upper clamping piece 6, make a call to three holes, by these three holes, 3240 thick epoxy resin bonded fiber 11 use bolts of 4mm are screwed on low pressure upper clamping piece, on glass-cloth board, make a call to four slotted holes, the low-voltage lead brace 3 of each phase is connected on low voltage conductive bar 10 through these four slotted holes and upper end, circuit is drawn to fuel tank, the lower end of low-voltage lead brace is through low-voltage lead copper bar 7 connecting coils, low voltage conductive bar overcoat has low pressure porcelain vase 2.
The utility model is not used wooden clamp plate holder low-voltage lead, has saved raw material, has reduced the production cost of product; The utility model is simple in structure, easy to operate, and workman while working very smoothly, has therefore improved production efficiency; The utility model not be used in welding lead support on low pressure upper clamping piece, does not therefore need polishing welding seams, and transformer semi-finished product presentation quality increases, not only save material but also enhance productivity, reduced welding sequence, workman works conveniently, solder joint is reduced, increased the aesthetics of product.
