Disconnecting Circuit Breaker

These combination switches are becoming more and more common in air insulated substations to save space. A simple switch=DCB would be enough I think. Gazer75 (talk) 16:30, 2 June 2020 (UTC)

As most circuit breakers can cut both normal and abnormal currents, I see no difference with common circuit breakers. Why should they be distinguised from other circuit breakers?

In air insulated substation, dedicated and cheaper disconnectors are here to save on usage of circuit breaker at every disctonnecting point, but you could only use circuit breakers if you want to Fanfouer (talk) 17:07, 3 June 2020 (UTC)

Nomal circuit breakers with vacume, oil or sf6 do not have a disconnector inside like the DCBs. They are there to protect from abnormal currents only, thus you also have to have a disconnector in the same bay. Gazer75 (talk) 17:41, 3 June 2020 (UTC)

Which type of switches are they?

Which type of switches are they?

On the left is the transformer, next the 3 switches and then the busbar follows.

You can find the place where the photo was taken here.

Can someone help me with the exact name? --geozeisig (talk) 09:25, 21 August 2020 (UTC)

Hi

1 is not a switch, it may be a current transformer for measurement purposes. I don't know OSM tagging for them currently

2 is a circuit breaker (switch=circuit_breaker). 3 phases are mechanically linked, then cables=3 is suitable here if all 3 circuit breakers are mapped on one single node.

3 is a disconnector (switch=disconnector). 3 phases are mechanically linked, then cables=3 is suitable here as well.

I think this situation is similar to yours
