GAS INSULATION SWITCHING DEVICE

摘要

In a double bus conductor type gas insulation switching device, a plurality of branch lead-out ports are provided at regular intervals (dimension H) along the vertical direction on the side face of the tank of a vertical circuit breaker (1), a line side apparatus is connected with the uppermost branch lead-out port, a bus side apparatus is connected with a branch lead-out port provided below, and the line side apparatus is arranged oppositely to the circuit breaker (1) while holding the double bus conductor therebetween thus constituting a unit (I) for transmission/reception line. In a unit (III) for bus conductor link line, length of the tank of a vertical circuit breaker (16) is set shorter by the dimension H than that of the circuit breaker (1), and the interval of the branch lead-out ports is set similarly to the dimension H for the plurality of branch lead-out ports provided along the vertical direction on the side face of the tank of the circuit breaker (16) for connecting with the bus side apparatus.
