Abstract
The invention relates to a transposed conductor with a continuously sensing function, which mainly comprises self-adhesive enameled flat wires and a covering insulating layer. The transposed conductor is characterized in that the self-adhesive enameled flat wires are arranged into two lines with mutually contacted narrow edges, a pressure strain element and a heat-sensitive element are arranged between two lines with mutually leaned narrow edges, a whole bundle of wires is formed through twisting transposition, and the covering insulating layer is enwound outside the whole bundle of the wires to form a whole body. The pressure stress element is formed by spot-welding pure copper wires on two surfaces of a polyimide substrate to form grid-type metal wires, then covering all the exposed grid-type metal wires by pressure sensitive adhesive tapes, heating the metal wires, and pressurizing and solidifying the metal wires and the pressure sensitive adhesive tapes into a whole body. The transposed conductor uses induction transposed conductors to coil a transformer coil, has the function of monitoring the deformation and the temperature rise of the coil in running at any time, and can take measures in time for hidden dangers so as to avoid transformer accidents; and in the use process, the status of the transposed conductor is controllable, and the induction sensitivity is improved.
Description
Technical field
The present invention relates to a kind of transposed conductor with continuous inducing function, specifically sensing element is made with transposed conductor and be embedded in the surface in advance and be bonded to one, STRESS VARIATION etc. between the reflection transposed conductor single line belongs to sensing technology and applies to the lead process technology.
Background technology
Transformer coil is in operation and can produces vibration and temperature rise, when circuit generation abnormal conditions, even can produce high vibration and short time high temperature.Vibrate and excessively may cause winding deformation, and the too high meeting of temperature makes wire insulation aging, these phenomenons all are to cause the hidden danger of Accident of Transformer.In the prior art, all be to become transformer coil around coil, optionally to arrange thermocouple according to sunykatuib analysis more afterwards winding transposition wire, to reach the purpose of monitoring temperature.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby provide a kind of transposed conductor with inducing function, it utilizes induction winding transposition wire transformer coil, possesses the function of monitoring operating deformation of coil and temperature rise at any time, can in time take measures to potential faults, avoid the generation of Accident of Transformer.
According to technical scheme provided by the invention, a kind of transposed conductor with inducing function, comprise self-adhesion enameled sheet wire, outer insulating layer coating, feature is: two row that the assortment of described self-adhesion enameled sheet wire becomes narrow limit to be in contact with one another, placement force strain gauge element and temperature-sensitive element in the middle of two row that lean on mutually on narrow limit, form whole bunch through transposition by twisting, insulating layer coating forms one outside twining outside whole bunch.
Described self-adhesion enameled sheet wire comprises lenticular wire copper conductor, acetal insulation enamelled coating, epoxy self-bonding layer, and described lenticular wire copper conductor applies acetal insulation enamelled coating outward, and acetal insulation enamelled coating applies the epoxy self-bonding layer outward.
Described pressure-strain element comprises polyimide base film, grid type wire, the pressure sensitive adhesive tape of dual coating fluororesin, fine copper wire point is welded on the polyimide base film two sides of dual coating fluororesin, form grid type wire, use pressure sensitive adhesive tape evenly to cover all exposed grid type wires then, after the heating again cure under pressure be integral.
The present invention is simple, compact and reasonable for structure; It utilizes induction winding transposition wire transformer coil, possesses the function of monitoring operating deformation of coil and temperature rise at any time, can in time take measures to potential faults, avoids the generation of Accident of Transformer; In use state is controlled, improves induction sensitivity.

Embodiment
Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
As Fig. 1～shown in Figure 4, comprise self-adhesion enameled sheet wire 1 (lenticular wire copper conductor 1-1, acetal insulation enamelled coating 1-2, epoxy self-bonding layer 1-3), pressure-strain element 2 (the polyimide base film 2-1 of dual coating fluororesin, grid type wire 2-2, pressure sensitive adhesive tape 2-3), temperature-sensitive element 3, outer insulating layer coating 4.
Two row that the present invention becomes narrow limit to be in contact with one another 1 assortment of self-adhesion enameled sheet wire, and sensing is carried out force analysis at the carrying and the approaching face of power, determine the position of sensing element, the pressure-strain element 2 and the temperature-sensitive element 3 of long rice number can be placed between transposed conductor two row accurately, enameled sheet wire 1 opposed in order be the transposition of direction, insulating layer coating 4 forms one through the traction compacting outside outermost layer is wrapped, reel according to the transformer core internal diameter.
Described self-adhesion enameled sheet wire 1 comprises lenticular wire copper conductor 1-1, acetal insulation enamelled coating 1-2, epoxy self-bonding layer 1-3, and described lenticular wire copper conductor 1-1 applies acetal insulation enamelled coating 1-2 outward, and acetal insulation enamelled coating 1-2 applies epoxy self-bonding layer 1-3 outward.
Consider that there are inductive reactions such as strong eddy current in transposed conductor coil environment for use, serious interference, and temperature fast rise thereupon when electromagnetic force sharply changes, so use two types the supporting use of sensing element, confirmation mutually, temperature-sensitive element 3 is selected the hot sensing of optical fiber type, pressure-strain element 2 adopts fine copper wire point is welded on the polyimide base film 2-1 two sides of dual coating fluororesin, form grid type wire 2-2, use pressure sensitive adhesive tape 2-3 evenly to cover all exposed grid type wire 2-2 then, after the heating again cure under pressure be integral.Because the length of transposed conductor is longer, general length surpasses 1000m, and present resistance strain gage can't satisfy instructions for use, so make the pressure-strain element of growth band forms according to sensing principle.
During use, power supply connected 2 opposite polarity loops when external inductor connect pressure-strain element 2, can determine the serious point of winding stress deformation according to increased resistance value, ahead of time protection.
