Abstract
The utility model discloses a kind of three-dimensional wound core dry type transformer clamp with good insulation properties, comprise upper clamping piece and lower clamping piece, and connect upper clamping piece and lower clamping piece draw screw rod, described upper clamping piece, lower clamping piece, draw on screw rod and be provided with insulating coating.Insulating coating makes folder possess certain electrical strength, width is to the coil of power transformer product and lead-in wire can being made folder and drawing the distance of screw rod to reduce 60%, axially axially upper and lower folder can will can be reduced 40% to the distance of coil, thus make product outer container size reduce 20%.Make power transformer product and outer container become compacter like this, the manufacturing cost of product can be reduced simultaneously, and can installing space be saved.
Description
Technical field
The utility model relates to transformer technology field, particularly relates to a kind of three-dimensional wound core dry type transformer clamp with good insulation properties.
Background technology
At present, the three-dimensional wound core dry type transformer clamp on market is steel and iron parts and does not carry out insulation processing, needs to amplify the main insulating structure of coil to folder to ensure the electrical strength of product when carrying out transformer device structure design for this reason.So substantially increase the consumption of steel and iron parts, and product design size is increased, outer container size also can increase thereupon, and then adds the manufacturing cost of power transformer product and outer container.
Utility model content
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of three-dimensional wound core dry type transformer clamp with good insulation properties.
The utility model is the technical scheme that technical solution problem adopts:
There is a three-dimensional wound core dry type transformer clamp for good insulation properties, comprise upper clamping piece and lower clamping piece, and connect upper clamping piece and lower clamping piece draw screw rod, described upper clamping piece, lower clamping piece, draw on screw rod and be provided with insulating coating.
Further, described insulating coating is epoxy coating.
Further, described upper clamping piece and lower clamping piece are the hexagonal-shaped frame of hollow.
Further, the middle position of described upper clamping piece, lower clamping piece is respectively equipped with triangle casting die, and each bight of described triangle casting die compresses single coil respectively, and upper and lower two triangle casting dies are connected by drawing screw rod.
Further, described coil upper surface and lower surface are respectively provided with four insulation pressing, and coil is compressed by insulation pressing by described upper clamping piece, lower clamping piece and triangle casting die.
The beneficial effects of the utility model are: a kind of three-dimensional wound core dry type transformer clamp with good insulation properties that the utility model adopts, at upper clamping piece, lower clamping piece, draw on screw rod insulating coating is set, insulating coating makes folder possess certain electrical strength, width is to the coil of power transformer product and lead-in wire can being made folder and drawing the distance of screw rod to reduce 60%, axially upper and lower folder can be reduced 40% to the distance of coil, thus make product outer container size reduce 20%.Make power transformer product and outer container become compacter like this, the manufacturing cost of product can be reduced simultaneously, and can installing space be saved.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and example, the utility model is described in further detail.
Fig. 1 is front view of the present utility model;
Fig. 2 is vertical view of the present utility model.
Embodiment
See figures.1.and.2, a kind of three-dimensional wound core dry type transformer clamp with good insulation properties of the present utility model, comprise upper clamping piece 2 and lower clamping piece 6, and connect upper clamping piece 2 and lower clamping piece 6 draw screw rod 7, described upper clamping piece 2, lower clamping piece 6, draw on screw rod 7 and be provided with insulating coating.Particularly, described insulating coating is the coating adopting epoxide resin material to coat.This insulating coating makes upper clamping piece 2, lower clamping piece 6 and draws screw rod 7 to possess certain electrical strength, can by the coil 4 of power transformer product and lead-in wire 8 pairs of upper clamping pieces 2, lower clamping pieces 6, draw the width of screw rod 7 to and axial distance reduce: width is to the coil 4 of power transformer product and lead-in wire 8 can being made upper and lower folder and drawing the distance of screw rod 7 to reduce 60%, axially axially upper and lower folder can will can be reduced 40% to distance D1, the D2 of coil 4, thus make product outer container size reduce 20%.Make power transformer product and outer container become compacter like this, both can reduce the manufacturing cost of product, can installing space be saved again.
In the present embodiment, described upper clamping piece 2 and lower clamping piece 6 are the hexagonal-shaped frame of hollow.Simultaneously for strengthening the structural strength of folder, the middle position of described upper clamping piece 2, lower clamping piece 6 is respectively equipped with triangle casting die 5, and each bight of described triangle casting die 5 compresses single coil 4 respectively.Described coil 4 upper surface and lower surface are respectively provided with four insulation pressing 3, and coil 4 is compressed by insulation pressing 3 by described upper clamping piece 2, lower clamping piece 6 and triangle casting die 5, and upper and lower two triangle casting dies 5 are connected by drawing screw rod 7.
The above, just preferred embodiment of the present utility model, the utility model is not limited to above-mentioned execution mode, as long as it reaches technique effect of the present utility model with identical means, all should belong to protection range of the present utility model.
