成果简介	NOVELTY - The resistor has an electrically insulating heat-conducting casing (1) made in the form of a hollow cylinder, inside which a heat resistive element (2) is located, and made in the form of a metal spiral located in a medium of pressed, heat-treated, heat-resistant heat-conducting material (3) at both ends of the resistive element current leads (4) are fixed. The electrically insulating heat-conducting casing is made in the form of metal rods attached to the resistive element. The sealing units are located in the annular gap between the casing and each current lead. The sealing unit is made in the form of a technological polymer sealant (5) filled on the outer side with a liquid elastic high-temperature sealant (6) in the annular gap between each current lead and a preheated casing with a heat-conducting material located in a preheated casing. The polymer sealant is made in an annular shape and is located around the current lead. USE - Constant resistor used in power electrical engineering. ADVANTAGE - The reliability of the resistor is increased by sealing, which is ensured by the fact that the constant resistor contains an electrically insulating heat-conducting casing. The resistor ensures a high level of operational reliability of the resistor and a high level of its operating voltage and electrical strength of insulation and high resistor power of up to 100 kW without deterioration of the electrical and thermal characteristics over time. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of a constant resistor. 1Electrically insulating heat-conducting casing 2Heated resistive element 3Heat-conducting material 4Resistive element current lead 5Polymer sealant 6Liquid elastic high-temperature sealant 7High-temperature solder
