When the coil assembly of the large-scale transformer is sleeved, the upper iron yoke needs to be disassembled, and after the coil assembly is sleeved, the silicon steel sheets of the upper iron yoke are sequentially reassembled, namely iron insertion is carried out. When the iron is inserted, the main-level silicon steel sheet is firstly inserted into the final stage from one side and then inserted into the other side, so that the main-level silicon steel sheet can topple over or generate waves in the iron inserting process, joints of the inserted iron are uneven, no-load loss of the transformer is increased, the clamping degree of an upper iron yoke is reduced, and noise of the transformer is increased.
At present, a steel plate and a door-shaped puller are commonly used for auxiliary iron insertion, the steel plate is 1000mm high, 2000mm long and 5mm thick, and the door-shaped puller is used for fixing the steel plate and part of main-grade silicon steel sheets together to meet the requirements of flatness and verticality. However, because the sizes of the silicon steel sheets of the iron yoke on different transformers are different, the silicon steel sheets cannot be used under the conditions of too long, too high, too short and the like, and because the door-shaped pickups are used, the width of the door-shaped pickups is generally 90mm, the silicon steel sheets cannot be used initially when the iron is inserted, and the positioning effect cannot be achieved.

Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of an embodiment of the present invention. An iron insertion positioning device comprising: the positioning device comprises a positioning cross beam 1 with adjustable length and more than two auxiliary inserting plates 2 with adjustable height, wherein the positioning cross beam 1 is vertically and fixedly connected with the auxiliary inserting plates 2. The positioning cross beam 1 and the auxiliary insertion plate 2 are respectively provided with fixing holes corresponding to the positions, and the positioning cross beam 1 and the auxiliary insertion plate 2 are fixed into a whole after bolts penetrate through the fixing holes.
The positioning cross beam 1 is preferably of a square tube structure and is made of stainless steel and carbon steel subjected to blackening treatment. Positioning beam 1 form through the bolt structure combination by the short side pipe of many different lengths, through bolted connection in order to make up different length between the short side pipe, positioning beam 1 can make up the length of going out and preferably: 3000mm, 2000mm and 1500 mm.
The auxiliary insertion plates 2 are made of stainless steel and carbon steel after blackening treatment, the number of the auxiliary insertion plates 2 is determined according to the number and the positions of the iron core columns and the width of the silicon steel sheet, and generally 2 auxiliary insertion plates 2 are used for one iron core column correspondingly; if the upper yoke silicon steel sheet of a core limb is particularly wide, 3-4 or more auxiliary insert plates 2 may be provided for one core limb. The height of the auxiliary inserting plate 2 which can be combined is preferably as follows: 370mm and 500 mm.
Because the iron inserting positioning device is composed of stainless steel and carbon steel after blackening treatment, the transformer cannot be polluted, the parts are very light, and the carrying and the disassembly are very convenient.
Fig. 2 is a schematic diagram of a field application of the embodiment of the present invention. According to the sizes (length and width) of the transformer iron core structure and the upper iron yoke silicon steel sheet, the length of the positioning beam 1 and the height of the auxiliary insertion plate 2 are adjusted, so that the iron insertion positioning device is adaptive to the sizes of the iron core structure and the silicon steel sheet; and determining the number of the auxiliary inserting plates 2 so that the iron inserting positioning device is adaptive to the sizes of the iron core structure and the silicon steel sheet.
When inserting iron, the auxiliary inserting plate 2 is inserted into the position 30mm away from the iron core oil duct of the main level of the iron core column, the insertion depth is not less than 100mm, and the action position of the positioning cross beam 1 is about 100mm above the center of the silicon steel sheet. The positioning cross beam 1 is fixed on the auxiliary inserting plate through bolts, and the positioning cross beam 1 can be freely overlapped to be in a proper length according to actual conditions.
The auxiliary insertion plate 2 is fixed in the iron core column and fixed with the positioning cross beam 1 through the auxiliary insertion plate 2, so that iron insertion positioning is realized. When inserting iron, the silicon steel sheet is guaranteed not to topple over through the structure that positioning beam 1 and supplementary picture peg 2 constitute, uses the contact of door type rake reinforcing positioning beam 1 and silicon steel sheet. Because the iron core column is fixed, the iron core can be positioned initially, so that the silicon steel sheet is not inclined, has no wave degree and has a smooth structure.
The iron inserting positioning device can realize the adjustment of the height and the length direction, ensure the flatness of the silicon steel sheet during iron inserting and is beneficial to clamping the silicon steel sheet; meanwhile, the iron inserting positioning device is light, so that the operation is convenient, and the production efficiency of the transformer is improved.
