Abstract

Automatic earth line detecting system for therapeutic electrostatic potential loading device is to secure grounding of a potential generator to protect a human body from danger of being electrificated by detecting leak current between each line of a commercial power source (particularly 100 volt a.c.) and an output, and connecting one line of the commercial power source judged as the grounding side with a grounding terminal. The earth line detecting system specifically designates one end of the power source 10 to be earthed, and can ensure a reliable earthing on the earth end 1a of the potential generator 1, thereby avoiding the occurrence of an electric shock on a human body.

The specific embodiment

Following with reference to description of drawings one embodiment of the present of invention.Fig. 1 is to use the connection layout of therapeutic apparatus of the treatment electrostatic potential loading device of one embodiment of the invention.Among Fig. 1, label 1 is the potential generator that produces the treatment electrostatic potential, and 1a is the lead-out terminal of this potential generator 1 output positive potential, and 1b is the ground terminal of output earthing potential.

The 3rd, insulation electrotherapy bed, the 4th, this insulation electrotherapy bed conductor inside, the 5th, insulator, the 6th, in adorn high-resistance negative electrode, the 7th, human body, 8a is the lead that is connected described potential generator 1, described insulation electrotherapy bed 3 and described negative electrode 6 with 8b, couples together like that as shown in the figure, treats with being applied to the electric charge that the described conductor 4 of described insulation electrotherapy bed 3 and the voltage between the human body 7 and electrostatic capacitance cause.

Fig. 2 is that the inside of the described potential generator 1 of one embodiment of the invention constitutes the block diagram that is connected with mains supply.Among Fig. 2, the 10th, single-phase 100V mains supply, the 11st, socket has

electrode

11a and 11b, and this electrode 11b detects the earth lead side that detects described mains supply by AC earth lead described later, and is connected ground connection with this earth lead.

The inside of potential generator 1 constitutes to be made up of the attaching plug 12 with

electrode

12a and 12b, electric fuse 13, circuit switching part 14, leakage current test section 15, ground connection connecting portion 16, control circuit 17, power supply unit 18, output circuit 19 and holding circuit 20 etc., and lead-out terminal 1a by the output positive potential and ground terminal 1b and external mechanical and human body couple together.
