Studies on Solutions and Constructive Trends of Remote Control and Telemonitoring of an Outdoor Railway High-Voltage Circuit Breaker

The main objective of this article consists in studying solutions and constructive trends of the remote control and telemonitoring system of a 27.5 kV high voltage vacuum switching bipolar circuit breaker. The proposed study creates the premises for the design, development and testing in laboratory conditions of an experimental model of a remote control and telemonitoring system of an outdoor bipolar high voltage circuit breaker with vacuum switching (U
n
=27.5 kV, I
n
=1250 A, I
k
=25 kA). This equipment is intended for substations in the railway system and is used to supply 25 kV power lines. The proposed circuit breaker is a component of the 696PED/2022 experimental-demonstration project referred to remote control and telemonitoring of a high-voltage switch, with vacuum switching, for the railway system.
