Abstract
The utility model relates to a switch transformer with a warning device. The switch transformer with the warning device comprises a metal shell and a magnetic core contained in the metal shell. A primary winding coil and a secondary winding coil are wound around the magnetic core, a fault detector is arranged in the metal shell and connected with a fault alarm, an insulating plate is arranged between the primary winding coil and the secondary winding coil, and the metal shell stretches to the two sides to form guide needles, sealing terminals and pins, wherein the sealing terminals and the pins are used for fixing the guide needles. The switch transformer with the warning device can detect current temperature and the circuit connection condition of the transformer in real time, problems can be found as soon as possible when faults occur, service life is long, the insulation grade is high, iron loss and copper loss caused by temperature rise of the transformer are effectively retarded, and the switch transformer with the warning device is convenient to manufacture, safe in use and capable of improving running reliability.
Description
Technical field
The utility model relates to transformer technology field, especially a kind of switch transformer with warning device.
Background technology
At present, the conventional switch transformer stitch being applied in power supply control all adopts staight needle formula, because the diameter of stitch is less, and can only be soldered to the cross section of pin diameter in when welding, long-term use meeting causes sealing-off because solder side is too little, affect useful life, because transformer loss is large, therefore its class of insulation is had relatively high expectations, traditional insulating material result of use is not ideal enough, and the easily electric shock harm causing because leak electricity in transformer bottom surface, therefore higher for the security requirement of switch transformer, traditional switch transformer cannot carry out fault detect, the transformer bad meeting of dispelling the heat causes excess Temperature and is short-circuited.
Utility model content
The technical problems to be solved in the utility model is: for overcoming the problem of above-mentioned existence, provide a kind of long service life, the switch transformer of what insulating properties was high have warning device.
The utility model solves the technical scheme that its technical problem adopts: a kind of switch transformer with warning device, there is the switch transformer of warning device, comprise metal shell and be housed in the magnetic core in metal shell, on described magnetic core, be wound with primary winding coil and secondary winding coil, in described metal shell, be provided with fault locator, described fault locator connects fault alarm, between described primary winding coil and secondary winding coil, be provided with insulation board, described metal shell to both sides be extended with draw pin and fixing described in draw hermetic terminal and the stitch of pin, described metal shell surface is wound around insulating tape.
Further, described fault locator inside is integrated with temperature-detecting device and circuit checker, the connection situation of Current Temperatures and the circuit of transformer can be detected in real time.
Further, described primary winding coil and secondary winding coil outside are all coated with polyester film, can play effective insulation effect, have enough heat resistances, and have certain corrosion resistance.
Further, described stitch upper end is provided with silica gel glass fibre sleeve, plays the effect of reinforcing, is not easy sealing-off.
Further, described insulation board is epoxy resins insulation plate, can play the effect of isolation, promotes insulation effect.
The beneficial effects of the utility model are, the switch transformer with warning device of the present utility model can detect the connection situation of Current Temperatures and the circuit of transformer in real time, while breaking down, can investigate as early as possible the place of ging wrong, stitch is provided with silica gel glass fibre sleeve, be not easy sealing-off, long service life, winding coil is coated with polyester film, the class of insulation is high, the iron loss and the copper loss that cause due to the temperature rise of transformer are effectively slowed down, easily manufactured, improve the operational reliability of the switch transformer with warning device, use safety.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is vertical view of the present utility model.
1. metal shells in figure, 2. primary winding coil, 3. secondary winding coil, 4. fault locator, 5. fault alarm, 6. insulation board, 7. stitch.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.
The switch transformer with warning device as shown in Fig. 1 Fig. 2, comprise metal shell 1 and be housed in the magnetic core in metal shell 1, on magnetic core, be wound with primary winding coil 2 and secondary winding coil 3, in metal shell 1, be provided with fault locator 4, fault locator 4 connects fault alarm 5, between primary winding coil 2 and secondary winding coil 3, be provided with insulation board 6, metal shell 1 is extended with to both sides and draws pin and fixedly draw hermetic terminal and the stitch 7 of pin, and metal shell 1 surface is wound around insulating tape.Fault locator 4 inside are integrated with temperature-detecting device and circuit checker, the connection situation of Current Temperatures and the circuit of transformer can be detected in real time.In the time that transformer temperature is too high, fault alarm 5 can send chimes of doom, simultaneously, when circuit is short-circuited or when the fault such as electric leakage, fault alarm 5 also can send chimes of doom, staff can be investigated as early as possible go wrong, convenient for maintaining, has effectively improved operating efficiency, has also improved fail safe.Primary winding coil 2 and secondary winding coil 3 outsides are all coated with polyester film, can play effective insulation effect, have enough heat resistances, and have certain corrosion resistance.Stitch 7 upper ends are provided with silica gel glass fibre sleeve, play the effect of reinforcing, are not easy sealing-off.Insulation board 6 is epoxy resins insulation plate, can play the effect of isolation, promotes insulation effect, and has effectively slowed down the iron loss and the copper loss that cause due to the temperature rise of transformer.
Taking above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this utility model technological thought, carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to claim scope.
