Abstract

The present invention provides a disconnection spark detecting circuit for a physical treatment device which can securely detect a disconnection spark caused by a defective contact of a treatment conductor. Two equally-divided first coils 6p1 and 6p2 are wound around the output line 2 for sensing to generate magnetic flux in reverse directions to each other, and a disconnection spark in said output line 2 is detected by the detection transformer 6 which takes out signals from a secondary coil 6s. In this way, a disconnection in the output line can be securely detected.

Description of the Invention (u), the additional waveform on the primary side cannot be transmitted to the secondary side. For the rectifier / integral circuit in Figure 1 7 No h voltage is applied and no detection output will be generated. The voltage of the high-frequency voltage generator 1 described above is often a voltage of several hundreds of volts. Therefore, the treatment conductor 3 becomes a poor contact under the influence of changes over the years and the like, thereby causing a disconnected discharge state. When such an output line is in a state caused by a disconnection discharge, as shown in an example in FIG. 2B: f, the primary waveform of the inspection transformer 7 is increased. In the above case κ, the primary induction coil of the inspection transformer 7 is divided into 6pl and 6p2, and a magnetic field in the opposite direction is induced by induction. Therefore, the fundamental wave component of the high-frequency voltage will cause the voltage on the secondary side. The discharge state in Figure 2B above Current is added to the primary induction coil, and then based on the passing current of the primary induction coils 6pl and 6p2 divided into two parts, high-frequency components will be caused in the secondary coil due to the imbalance of the magnetic field. The high-frequency component signal caused by the secondary induction coil converts the DC signal into a detection output in the rectification / product-free circuit V, but it is not shown in the figure, and the abnormality detection circuit is driven. Next, in the disconnection discharge detection circuit of Fig. 3, please refer to the description of Fig. 3 for the structure of the transformer used for inspection. In this figure, the detecting transformer 8 is the same as the detecting transformer 7 of Fig. 1. This instrument for testing 8 has two toroidal cores (Torial Dial coils and cores) 8c1 '8c2, and 2 times rK' '· Interconnected (1 nter-1 ink) response j _ 8pl, 8P2 is shown as L in the second figure.

Description of the invention u) The direction of the magnetic field is shown as arrow A, and the direction of the magnetic field of the iron core 8c2 is shown as arrow B, so the magnetic fields in the secondary induction coil cancel each other out. No voltage holding effect is generated for the fundamental wave of the flowing current. As the toroidal core used, the thickness of the core used is light and small, and the influence of external interference from each individual direction can be reduced. The secondary induction coil can No external interference is generated. Above, the operation of one embodiment of the present invention, please refer to the figure In conjunction with the detailed description above, the present invention is not limited to this embodiment, and design changes made without departing from the scope of the present invention are included in the present invention. For example, as the above-mentioned two ring cores 8cl and 8c2, the number of cycles used In the field of high-frequency modulation, it is sufficient to use materials with mutually different characteristics and to take out the effects of the high-frequency component signals. Furthermore, the use of the abnormality check signal described above can also easily output an alarm based on sound or light, such as the power supply of a device. OFF, the output line can also be OFF. As explained above, if the present invention uses a high-frequency voltage for a therapeutic conductor to perform charge therapy on a human body, the object is separated from the therapeutic device by an output line so that it is divided into two equal parts. The primary induction coil generates a magnetic field in the opposite direction. According to the signal taken from the secondary induction coil in the detection transformer, the output line is disconnected. This output line and the disconnection detection circuit are electrically separated, which is not easily affected by external interference. Influence, the structure of the output line disconnection check circuit can obtain good results. Although the present invention The best embodiment is disclosed as above, but it is not intended to limit the present invention. Anyone skilled in this art can make various modifications and retouches without departing from the spirit and scope of the present invention.
