Abstract
THE PURPOSE. To justify the need to use an arc breakdown protection device (ABPD) in electrical networks up to 0.4 kV, in order to reduce the number of fires. To analyze the existing types of damage, compare the protection devices against various types of damage in electrical networks up to 0.4 kV. To consider the requirements for ABPD, as well as the main characteristics of protection devices and types of execution. To determine the area of application of the ABPD in electrical installations for various purposes. METHODS. To solve the problems associated with the peculiarities of the arc processes in various electrical circuits and the lack of criteria for many key parameters in terms of the requirements and applicability of the ABPD, it was proposed to conduct a series of tests for specific network parameters in order to understand whether a case can really take place in the current power system when ABPD will not work properly. RESULTS. A test bench has been developed for testing the protection devices against arc breakdown and spark gaps for the effectiveness of operation for specific network conditions, instructions for its operation are given. CONCLUSION. It has been established that a sequential arc breakdown can only switch off an arc breakdown protection device (ABPD) and, accordingly, increase the safety of operation of electrical networks up to 0.4 kV in order to reduce fires caused by violation of the rules for the design and operation of electrical equipment. The proposed device for testing protection devices against arc breakdown and spark gaps allows you to control the fact of mandatory operation of the ultrasonic detector for a certain time and formulate the requirements necessary for the design of power grids.
