BACKGROUND OF THE INVENTION The present invention relates to a high-voltage switch for switching high-voltage output electrical power to various types of high-voltage or high-voltage generators of high-voltage output having the ability to change the polarity of the output electrical quantity, the fastest, reliability and safety changes. In the case of high-voltage stabilizers, it is most necessary to change the polarity of the output and electrical variables and the nature of the poor linkage of the regulator and the object stabilizer so that this poor bonding of the strand is the nature of a bad bond. In solutions of prior art high voltage stabilizers and generators of high voltage, the change in the polarity of the output electric current is usually solved in a complex manner, for example by two or more - in the case of an external multiplier by connectors - or by a switch, high voltage. relays and the like. The correct nature of the feedback of the stabilizer control circuit relative to the output polarity is usually set separately by the operator of the device, causing a risk of device failure in the case of unqualified or inattentive operators.

The above drawbacks are eliminated by the high voltage switch to switch the polarity of the output electrical variable rotatably mounted in the base body according to the invention, the principle being that zero contact and rotary contact are disposed on the front face of the rotor and the front face on the side there is a slidably mounted high-voltage connector and a protruding gripped position identifier, wherein in the rotational contact there is in its shaped opening a first sliding contact, which is insulated by a conductor, passing through an aperture formed centrally in the rotor and in the high-voltage connector connected to the outlet a clamp, wherein the null contact is connected to the zero potential by means of a resilient connection, passing through a hole formed eccentrically in the rotor, and a second slip contact is disposed on the rotational contact, and a third sliding contact is disposed at zero contact, wherein the switch is equipped with a zero terminal with zero potential. Further, the position identifier is in contact with the first position sensor connected to its first terminal and locked by the first detent device, the second position sensor with its second terminal and its second detent device being locked against the first position sensor. The advantages of a high voltage switch to switch the polarity of the high voltage output variable define the zero potential of one positive or negative - two output terminals of the high-voltage generator or stabilizer. This high-voltage generator is not otherwise coupled to zero potential. The remaining high voltage generator terminal forms the high voltage output terminal of the electrical output with a defined type of polarity to the zero potential of the device.

The invention is illustrated in the accompanying drawing in which Fig. 1 is a cross-sectional view of the B-B high-voltage switch and Fig. 2 is a sectional view of the A-A high-voltage switch. In the base body 1 of the switch, there is a rotatably mounted rotor 2 which carries a neutral contact 3, a rotary contact 4 and a positional identifier 5,. A removable 3-22S 449 high voltage connector 6 is inserted into the rotor 2 by means of which a high voltage output variable can be output to the output terminal 2 via an insulated conductor & which is connected to the output variable potential on the high voltage connector 4 side. the first sliding contact 9 is connected to the rotary contact 4 when the high-voltage connector 6 is inserted into the rotor 2. The neutral contact 4 is provided with a neutral contact 3 which is always connected to zero at any position of the rotor 2. the potential of the high-voltage switch by means of a flexible connection 10 which allows such a connection even in the case of zero contact rotation 3.0 According to FIG. 1, the positive output terminal 11 of the high voltage generator 19 at the given position of the rotor 2 is conductively connected with rotary contact 4 using a second sliding contact 13. The negative output terminal 12 of the high voltage generator 19 is conductively connected to the rotary zero contact 3 by the sliding contact 14 at the same rotor position 2. The semiconductor identifier 2 rotates together with the rotor 2 and the semi-circle, whose end points are defined by the first position sensor 16 and the second position sensor 17. They form, in conjunction with the position identifier 2, the rotational stop stops 2 required for the correct positioning of the second sliding contact 13 and the third sliding contact 14, but the first and second position sensors 16 and 17 respectively. providing electrical position signals at the first terminal 18 and the second terminal 19. These signals are of logical type and include information about the currently set polarity of the output electrical quantity, which is required for automatically adjusting the correct characteristic of the generator 19 in case it is connected as a stabilizer high voltage output j electrical value. When the positional identifier 2, when rotating the rotor 2, reaches the minimum distance from the respective first position sensor 16 and the second position sensor 17, respectively, the first detent device 20 and the second detector device 21, which prevent the rotor from rotating 2 «Polarity». the high-voltage output electrode 4 - 225 449 of the magnitude 23 is always unambiguously defined with respect to the zero potential of the zero terminal 22, which can be either a virtual or a fixed zero instrument potential.

The function of the high voltage switch is as follows: As the first position, as shown in the enclosed drawing, is one high voltage pole from the high voltage generator 15 via its positive output terminal 11, via the second sliding contact 13, through the rotary contact 4, through its first slip contact 2 »via insulated wire & to the output terminal 2 · The second pole of the voltage is fed from the negative output terminal 12 via the third sliding contact 14, which is the null contact 3, through the resilient connection 10 to the zero potential of the null terminal 22, the high voltage switch is in the second where the rotary contact 4 is connected to the third sliding contact 14 and the neutral contact 3 is connected to the second sliding contact 13 ", thereby switching the polarity of the high-voltage output electrical variable.
