Abstract |
The purpose and objectives of this research is to develop methods to improve the efficiency of the protection devices of telecommunications systems when exposed to external pulsed electromagnetic interference. Develop requirements for the speed of protection devices of telecommunication networks, consistent with the volt-second characteristics of the protected equipment. Develop recommendations on drawing up diagrams of cascades of telecommunications equipment protection devices. We used the methods of statistical analysis, graph theory, methods for calculating and converting electrical circuits with complex variables, direct and inverse Fourier transforms, numerical methods for solving differential equations and simulation modeling of dynamic characteristics and SPD start-up circuits. High efficiency of the telecommunications network elements can be ensured only under the condition of their uninterrupted operation. In this regard, the task of improving the reliability of the existing means of protection equipment transmission systems when exposed to external electromagnetic fields is relevant. A developed method for calculating the amplitude-time characteristics of induced voltages and currents in a line with distributed parameters of a finite length, loaded with time-varying resistance of an SPD, is proposed for use in designing networks, systems and telecommunications devices to improve performance, under the influence of external pulsed electromagnetic fields. |
