The invention belongs to the technical field of pole-mounted circuit breakers in power systems, and particularly relates to a pole-mounted
circuit breaker integrating communication,
electricity taking and traveling wave
distance measurement. The
solid-sealed polar pole is located on the box body, an integrated
capacitor C1 is arranged in the
solid-sealed polar pole, and the wire inlet side of the integrated
capacitor C1 is a high-
voltage terminal; a
secondary side circuit is arranged in the box body, a self-integrated
capacitor C1 is sequentially connected in series with low-
voltage capacitors C2 and C3 of a capacitor
electricity-taking power supply and a high-frequency
transformer T2, and a power-frequency
electricity-taking
transformer T1 is connected in parallel with the C2 and C3; the protection circuit is connected to the C3 in parallel; the high-frequency
transformer T2 has two groups of output windings, one group of output windings is connected in series with the traveling wave acquisition circuit, and the other group of output windings is connected in series with the carrier communication circuit. Original four independent devices are integrated into one device, functions are deeply integrated, the limitation that in a traditional scheme, a plurality of devices achieve a single function is broken through, high integration of the devices is achieved, the number of the devices and the installation space are reduced, and the installation and maintenance cost is reduced.
