成果简介	NOVELTY - Invention relates to electrical engineering, namely to relay protection equipment. Device of combined current conductor protection contains current-carrying bus fixed on insulators inside current conductor casing. At that, current conductor combined current protection device is equipped with plate with first and second inductance coils fixed on its outer side, to which inputs of first and second voltage amplifiers are connected, respectively, support plate, first and second motors with their own first and second drive shafts, four planks, first lugs installed on lateral sides of support plate and located in them first running axes, hollow cylinder installed on the second plank, Limiting stop located on the second drive shaft and made in the form of a round disc, the second lugs installed on sides of the plate and located in them the second running axes. Also, the device for combined current conductor protection includes a time relay with a contact with time delay for closing, a direct current source, two intermediate relays, two indicating relays and a tripping coil of the current conductor circuit breaker. First and second engines are fixed on the first and third planks, respectively. First and second planks are attached to the current conductor casing. Plate with first and second inductance coils is made with possibility of transverse movement inside current conductor by means of first motor along first drive shaft to hollow cylinder, and also with possibility of longitudinal movement relative to current-carrying bus with the help of second motor along second drive shaft to limit stop. First and the second motors are fixed on the first and the third planks, respectively, and are made with possibility of connection of a microcontroller to control their movement. Outputs of the first voltage amplifier are connected to the winding of the time relay, the contact with time delay for closing of which is connected to the direct current source, and the winding of the first intermediate relay is connected to its output, the outputs of the second voltage amplifier are connected to the winding of the second intermediate relay, inputs of the first and second indicating relays are connected to outputs of contacts and the first and second intermediate relays, and current conductor breaker tripping coil is connected to their outputs. USE - Electrical engineering. ADVANTAGE - Increasing the reliability and expanding the functionality of combined current protection for TEKN type current conductors with voltage of 6-10 kV. 1 cl, 3 dwg
