Abstract
The utility model relates to the technical field of transformer parts, in particular to a transformer footrest lower part positioning device which comprises a positioning peg (1), a footrest soleplate (3), an insulating rubber plate (4), fastening pieces (2) and an insulating device. The positioning peg (1) is fixedly connected with the lower segment of an oil tank (5); the footrest soleplate (3) and the insulating rubber plate (4) pass through the positioning peg (1) and then are fixed with the lower segment of the oil tank (5) through the fastening pieces (2); and the insulating device is arranged among the footrest soleplate (3), the positioning peg (1) and the fastening piece (2). By insulating the footrest soleplate (3) with the positioning peg (1) and the lower segment of the oil tank (5), the transformer footrest lower part positioning device ensures that the clamping pieces and the side beams connected on the footrest soleplate can not be grounded through the lower segment of the oil tank (5), and instead, the clamping pieces can be led out to be grounded separately, so that detection and maintenance are facilitated. The transformer footrest lower part positioning device improves the safety operation coefficient of the transformer and increases the long-term operation reliability of the transformer, and has the advantages of reasonable structure, convenient operation, low cost and easy installation.
Description
Technical field
The utility model relates to a kind of transformer part technical field, specifically a kind of transformer pad underfooting portion positioner.
Background technology
At present, traditional transformer pad underfooting portion location structure is: locating pin is welded in lower oil tank, after the pad sole passes locating pin, to fill up sole and pad connector such as the folder etc. on the sole by nuts and washers and fix, thereby reach the purpose of the unshakable in one's determination and folder of stationary transformer with lower oil tank.But because folder from top to bottom unshakable in one's determination, the arm-tie unshakable in one's determination of common transformer; curb girder pad pin all is to have connected into as a whole by bolt; though between pad sole and the lower oil tank insulation offset plate is set; but the pad sole contacts with locating pin regular meeting in running; cause the pad sole to be connected with lower oil tank by locating pin; therefore and the folder on the pad sole also can only pass through lower oil tank ground connection, can't draw separately, can not detect transformer inside folder to earth-current.When break down or have hidden danger in the transformer part, can not grasp transformer internal operation situation rapidly, thereby make accurate judgement, rapidly removing faults or remove a hidden danger.
Summary of the invention
The purpose of this utility model provides a kind of transformer pad underfooting portion positioner, make folder, pad sole, curb girder etc. and lower oil tank insulation, folder can be drawn separately, is convenient to safeguard, detect, improve the safe operation coefficient of transformer, strengthen the reliability of long-time running.
The purpose of this utility model realizes by following new construction: a kind of transformer pad underfooting portion positioner, comprise locating pin, securing member, pad sole and insulation offset plate, locating pin is fixedlyed connected with lower oil tank, pad sole bottom is provided with the insulation offset plate, pad sole and insulation offset plate are fixed its and lower oil tank by securing member after passing locating pin, are provided with seal filling up between sole and locating pin, the securing member.
Described seal comprises insulating washer and insulated tube, and insulating washer is arranged between pad sole and the locating pin, and insulated tube is arranged between pad sole and the securing member.
Described insulated tube can be insulating paper pipe or phenolic aldehyde paper tube.
Because the utility model is all adopting seal at interval between pad sole and the packing ring and between pad sole and the locating pin, the pad sole can be connected with lower oil tank by locating pin, guaranteeing to fill up the folder that connects on the sole, curb girder etc. can be therefore by lower oil tank ground connection, folder can be drawn ground connection separately, be convenient to detect and maintenance, improve transformer safe operation coefficient, strengthened the long-time running reliability.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model
Embodiment
Now in conjunction with the accompanying drawings the utility model is further described, Fig. 1 is a kind of embodiment of the present utility model, comprises locating pin 1, pad sole 3, insulation offset plate 4, securing member 2 and seal etc.Locating pin 1 is welded on the boxboard of lower oil tank 5, in pad sole 3 bottoms insulation offset plate 4 is set, after insulation offset plate 4, pad sole 3 pass locating pin 1, with securing member 2 that itself and lower oil tank 5 is fixing, securing member 2 can adopt nuts and washers etc., what present embodiment adopted is that two nuts and a packing ring are fastening from the top of pad sole 3 by locating pin 1, is provided with seal between pad sole 3 and locating pin 1 and securing member 2.Seal comprises insulating washer 6 and insulated tube 7 in the present embodiment, and insulating washer 6 is arranged between pad sole 3 and the securing member 2; Insulated tube 7 is arranged between pad sole 3 and the locating pin 1.Insulated tube 7 of the present utility model can be that the insulation paper tube also can be the phenolic aldehyde paper tube.
The utility model is guaranteed the feet base plate with feet base plate and locating pin and lower oil tank insulation The folder of upper connection, curb girder etc. can be therefore by lower oil tank ground connection, and folder can be drawn separately ground connection, Be convenient to detect and maintenance, improved transformer safe operation coefficient, strengthen the long-time running reliability, tool Have rational in infrastructurely, easy to operate, cost is low, be easy to the characteristics such as installation.
