Abstract
The utility model relates to a paper-covered copper flat wire with a continuous induction function, which mainly comprises a flat wire copper conductor and an external insulating layer and is characterized in that a pressure strain element and a thermo-sensitive element are arranged on the flat wire copper conductor and are subjected to transposition by twisting to form a whole bundle of wire; the whole bundle of wire is wound with the external insulating layer to form into the whole body; the pressure strain element comprises a polyimide substrate with both surfaces coated with fluororesin, grating-type metal wires and a pressure sensitive adhesive tape; pure copper metal wires are subjected to spot welding on the both surfaces of the polyimide substrate with both surfaces coated with fluororesin to form the grating-type metal wires; then the pressure sensitive adhesive tape is uniformly covered on all the bare grating-type metal wires; and the grating-type metal wires and the pressure sensitive adhesive tape are heated, pressurized and cured into one body. Since the induction paper-covered copper flat wires are utilized to wind a transformer coil, the utility model has the function of monitoring deformation and temperature rising in the operating process of the coil at any time, can adopt measures for fault hidden dangers in time to avoid a transformer accident, has controllable condition in the using process and improves induction sensitivity.
Description
Technical field
The utility model relates to a kind of paper bag copper strap wire with continuous inducing function, specifically sensing element is made with the paper bag copper strap wire and be embedded in the surface in advance and be bonded to one, STRESS VARIATION etc. between each circle of reflection paper bag copper strap wire 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 purpose of this utility model is to overcome above-mentioned weak point, thereby provide a kind of paper bag copper strap wire with continuous inducing function, it utilizes induction paper bag copper strap wire coiling 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.
The technical scheme that provides according to the utility model, a kind of paper bag copper strap wire with continuous inducing function, comprise lenticular wire copper conductor, outer insulating layer coating, feature is: placement force strain gauge element and temperature-sensitive element above the described lenticular wire copper conductor, form whole bunch through transposition by twisting, insulating layer coating forms one outside twining outside whole bunch.
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 utility model is simple, compact and reasonable for structure; It utilizes induction paper bag copper strap wire coiling transformer coil, possesses the function of monitoring operating deformation of coil and temperature rise at any time, can in time take potential faults
The generation of Accident of Transformer is avoided in measure; In use state is controlled, improves induction sensitivity.
Description of drawings
Fig. 1 is the utility model structural section schematic diagram;
The pressure-strain element pedion schematic diagram of Fig. 2 for relating in the utility model
Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
As Fig. 1～shown in Figure 2, comprise lenticular wire copper conductor 1, 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 and outer insulating layer coating 4.
The utility model is incited somebody to action 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 on above the lenticular wire copper conductor 1 (wide face) accurately, lenticular wire copper conductor 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.
Consider that there are inductive reactions such as strong eddy current in paper bag copper strap wire 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 is welded in fine copper wire point 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 lead 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.
