<p>PROBLEM TO BE SOLVED: To improve installation efficiency of a gas insulated on/off device by arranging an operation machine at the lower portion of a circuit breaker and at the same time fixing a trestle for instructing a line side unit in the box of the circuit breaker unit, and providing a leg at the opposite side of the operation machine of the trestle removably. SOLUTION: A line side unit 3 is connected and fixed to a circuit breaker unit 2 by a bolt via an insulation spacer 10 that is installed for airtight retention. Then, the circuit breaker unit 2 is fixed to the box of an operation equipment 4 for the circuit breaker by a flange provided at the lower end of a container 16a. Also, a trestle 37 is provided at the lower portion of the line side unit 3, and two legs 45 are mounted to a position that is opposite to the trestle 37 and the circuit breaker unit 2. Then, the line unit 3 is supported by the trestle 37 that is fixed to the box of the operation equipment 4, thus removing the legs 45 when mounting a current transformer 41 or the like.</p> |
