Disconnecting Circuit Breaker | Introductory Guide | TheElectricalGuy

Get introduced with the disconnecting circuit breaker (DCB) with this easy to understand video with 3D animation. Disconnecting circuit breaker is simple terms is a combination of a circuit breaker and a disconnector. Two functionalities in one device.

So helpful as always. Specifically the 3D model made it extremely understandable. Thanks indeed

[mulengakalyafye]

please do performance of transmission lines.... current, resistance, capacitance, sending end and receiving end voltages

If we are planning to phase out SF6, then what can we replace it with in these DCBs?

[EdEOS]

This is cool, what about the visual proof of the specific circuit isolation from the rest of the circuit? ( maintenance folks always want to see that) and clearance ground to the disconnect switch?

[chrisnachos]

Is the lack of visual proof a big negative? How can you be sure it is isolated before earthing? Current transformer to measure the current downstream or something else?

[adnantanjir]

How did you make this 3D video. Thats awesome brother. Make it easy to understand the topic.

How these C.B. CAN BE USED FOR EHV LINES IN GREED ? Supply is present from both side. These can be suitable for Transformer breaker, but not for ICT.

Una desventaja que puedo encontrar, por ejemplo: en una subestación de 220 KV de una central de generación; para poder darle el mantenimiento a su transformador de potencia de salida, necesitaría también poner fuera de servicio la línea de transmisión. Con la configuración antigua puedo abrir el interruptor, abrir el seccionador de barra (lado del transformador) y cerrar el seccionado a tierra del lado del transformador y mantener la línea de transmisión energizada. Con la configuración actual al tener un solo seccionador e tierra no podría aterrar mientras no ponga fuera de servicio a la línea.

TRADUCCIÓN: "One disadvantage I can find, for example, in a 220 kV substation of a generation plant, is that in order to perform maintenance on its output power transformer, I would also need to take the transmission line out of service. With the old configuration, I can open the circuit breaker, open the bus disconnect switch (on the transformer side), and close the ground disconnect switch on the transformer side, keeping the transmission line energized. With the current configuration, having only one ground disconnect switch, I wouldn't be able to ground while the line remains in service."

Have you heard of a HV disconnecting "switch" (breaker)? That crazy thing Americans have
