Description

The invention relates to electrical engineering, as well as to the field of labor protection and safety, and can be used to accumulate the energy of the electrostatic field or directly power consumers of electric current, while ensuring increased electrostatic safety.

Known devices that convert the energy of an electrostatic field into the energy of an electric current and provide electrostatic safety. These are various grounding systems that contribute to the discharge of electrostatic charge to the ground: anti-electrostatic rings, bracelets and straps [GOST 12.4.124-83 SSBT. Protective equipment against static electricity. General technical requirements. M .: IPK Publishing house of standards, 1983. - S.2-4 .; GB 2279875, A61N 1/14, H02B 3/00, published 1995; US patent 4373175, A61N 1/14, H05F02, published 1983], reducing the electrostatic potential of the human body; various contacting devices for removing electrostatic charge from surrounding objects [patent RU 2205524, H05F 3/02, published 2003], including those recommended for use in the electronics industry [patent DE 2621672, A61N 1/14, A61N 1/00, H05F 3 / 00 published 1977; patent RU 2288551, H05F 3/02, published 2006]; antistats for the removal of static charges from moving objects, such as vehicles [patent GB 2180204, B60R 16/06, H05F 3/02, published 1987] or when draining (filling) flammable liquids [RU 2160977, H05F 3/02, published 2000].

The disadvantage of these devices is that they provide only the removal of the formed electrostatic charges, but do not involve the use of electrostatic field energy.

The closest technical solution adopted for the prototype is an antistatic bracelet [USSR copyright certificate 997266, H05F 3/02, published 1983, bull. No. 6]. The prototype diagram is presented in figure 1 (1 - body, 2 - metal base, 3 - upper metal electrode, 4 - nonlinear resistance). This device is used to combat the harmful effects of static electricity, ensuring the discharge of electrostatic charge from an electrified object.

The disadvantage of the prototype is the inability to use the energy of the electrostatic field.

The task of the invention is to use the energy of the electrostatic field of charges formed on the surfaces of materials as a result of their natural electrification during interaction, for example, to charge a battery.

The problem is solved in that in the device (figure 2), containing a body of insulating material 1 with a contact element (metal base) 2 and the upper metal electrode 3, between which the nonlinear resistance 4 is located, a rectifier bridge 5 is introduced, and the first output of the variable the current of the rectifier bridge 5 is connected to the upper metal electrode 3, the second AC terminal of the rectifier bridge 5 is connected to the common bus, the positive terminal of the rectifier bridge 5 is the first output of the device wa 6, and the negative output of the rectifier bridge 5 - the second output of the device 7.

The energy of the electrostatic field arising in the processes of natural electrification is negligible. So the energy of the electrostatic field created by man at a potential on his surface of 25 kV, taking into account the average capacity of the human body of 350 pF, is of the order of 0.1 J. Moreover, static electricity is characterized by a fairly high voltage - tens of kilovolts, and a very small electric current . Therefore, the best way to use the energy of the electrostatic field is to charge the battery 8 (figure 2) or power low-power consumers of electric current having high resistance 9, such as an electronic clock, various sensors.

The proposed device for using the energy of the electrostatic field provides the work of consumers of electric current, while reducing the electrostatic charge that accumulates directly on the clothes and body of a person, as well as on the working surfaces of tables, chairs and other surrounding objects, including devices under voltage.

The principle of operation of the proposed device for using the energy of the electrostatic field is as follows: the high potential of static electricity through the contact element, the ground circuit and the rectifier bridge creates electric current through the battery, charging it, and, if necessary, directly provides power to consumers of electric current. The rectifier bridge provides the necessary polarity of the current through the battery.

Thus, the technical result of the invention is to use the energy of the electrostatic field resulting from the natural electrification of materials, for example, to charge the battery, and expand the functionality of systems that provide electrostatic safety.
