Particularities of conducting emergency processes in electrical transportation facilities at the electric stake dalliance: Generator – battery

Abstract

The article presents the results and identified problems in the context of conducting comprehensive expert investigations into emergency conditions and the operation of electrical equipment of transport vehicles in the electric stake area: generator – rechargeable battery. Electrical devices are a significant part of the causes of fires in transport vehicles. All electrical devices in the car are connected to the main power supply, battery and generator, through additional wiring. the structure of electrical wiring consists of a conductor, which transmits electrical signals, and an insulator, which releases the conductor. Basically, the shape and structure of the conductor, as well as the thickness of the insulator, are divided differently depending on the difference in the permissible flow. It is therefore not safe to adjust the connector that connects a number of electrical devices to one device, or it is inadvisable to connect external wiring to connect several electrical devices. If the re-engineering is blocked, which exceeds the permissible flow at the lance, there may be a short-circuit in the electrical wiring and damage to the insulation due to overheating, which can lead to a direct risk of seizing the car. It is common knowledge that among the most common causes of fires are wiring faults, which most often lead to a short circuit. If the insulation is damaged for these and other reasons, the exposed parts of the wires have the potential to come into contact with each other or with the “mass” of the car. the darts, as a result of the flow of a short flow through them, which is too great for passing through this crossbar, begin to heat up. Due to the high temperature, the insulation melts and ignites, along with adjacent parts made of plastic and other flammable materials. Based on the results of the investigation, it was established that the cause of the fire in the monitored car was the manifestation of the thermal effect of an electric shock in the installed core, which called for the insulation of the wire along which we will make constructive decisions during the operation of the internal combustion engine installed on the vehicle, so that a stream is supplied from the vehicle generator to the on-board electrical system. The diversity of current transport means of foreign production and the constant development of their electrical design necessitates the need for thorough development of the information base. creation of available operating evidence, methods of conducting examinations and expert investigations of electrical equipment
