DEVICE AND METHOD FOR FAST CLOSING CIRCUIT OF ELECTRIC CIRCUIT AND USE OF THIS DEVICE Russian patent published in 2015 - IPC H01T2/02 

FIELD: electricity.

SUBSTANCE: device for quick closing of an electric circuit has the main spark interval with the main electrodes and the starting device which has an additional spark interval with additional electrodes for ignition of electric arch in the main spark interval. Additional electrodes are screened from the main spark interval by means of the shielding unit (4) with the channel device (9, 10) passing through it from the outer side (11) of the additional spark interval to the outer side (12) of the main spark intervals of the shielding unit (4). The device also contains a nozzle (6) with the first end closest to the additional spark interval and with the second end, closest to the main spark interval. The first end has an inlet hole (7) which is interconnects with the channel device (9, 10), and the second end has an outlet hole (8).

EFFECT: possibility of activation of the main spark interval multiple times without the need for intermediate maintenance of the device.
