DEVELOPMENT OF THE SOCKET MODULE OF THE ELECTRICAL NETWORK

Abstract

Purpose of the work is to determine the method of emergency de-energization of the object by cutting stranded live wires without the manifestation of emergency modes of electrical networks. Methods. As research methods, a comprehensive approach is used, which includes the analysis of research on emergency de-energization, laboratory research to determine a safe way to cut stranded wires under voltage. Results. De-energizing various objects during rescue operations and firefighting is one of the important tasks that must be performed in order to create safe working conditions for rescuers themselves. It is established that one of the ways by which it is possible to cut live multicore wires without short circuits is the use of abrasive cutting discs made of rotating electrocorundum. The design of a device for trouble-free cutting of live wires, which has a rod, a cutting element, a transmission mechanism and a device for fixing the wire. In the middle of the rod is a transmission mechanism, which is used as a shaft, one end of which is connected to the motor, and the other end through a gearbox, which is fixed to the device for fixing the wire, with a cutting element. In the laboratory conducted experimental studies that showed that the cutting of wires occurs without the manifestation of dangerous factors of electric current – short circuits, sparks, electric arcs. Scientific novelty. Approaches to cutting live multicore wires with corundum disks are substantiated, which excludes the occurrence of emergency modes of electrical networks, in particular short circuits. Practical significance. The obtained results can be used to create tools for safe emergency de-energization, which creates the preconditions for improving the safety of this type of work.
