Узагальнення експериментальних досліджень. Підготовка наукового проміжного звіту. Head Savitsky Vladimir Nikolaevich, Registration Date 22-12-2004 Organization Ukrainian Scientific-Research, Designing and Technological Institute of Explosionproof and Mine Electrical Equipment with Research-Experimental Production popup.description2 Generalization of experimental studies of processes is Organized in distributing sets by voltage 1140 В at switchings of electric motors with two velocities by power 250/85 кВт, on the base which is designed algorithm, structured and circuitry of devices of said electric motor management. The analysis of element base is organized For physical realization of schemes for protected from blast of devices of switching, are shown their defect, and is developped variety of new elements, which will allow to develop the modern most latest devices of management and protection. Amongst them - sensors of current on 32 - 500 А, which differ the small size, linear features, devices of visual checking the value of load, devices warm-up and current protection of electric motors, made on modern high integrated schemes with provision for their individual features. They Are Organized their stand test, which have allowed to do the findings about correctness accepted decision. Developped new element base wake;arise prescribed in base of creation new modern protected from blast of devices. Product Description popup.authors popup.nrat_date 2020-04-02 Close
