<p>PROBLEM TO BE SOLVED: To make it possible to check one of systems in maintenance, together with a control power system, while the other system is in an operational state in a gas insulation breaker operated in a double measurement method or having one measurement and a bypass circuit. SOLUTION: A gas insulation breaker includes two measurement voltage/ current transformer units PU, and a connection unit CU for connecting the primary and secondary sides of the two units PU, and a transformer connection unit TU for connecting an incoming power unit LU and the transformer. In this case, each connection unit is made up of two breakers 1 and 4, and two grounding breakers 2 and 3. One breaker and one grounding breaker are stored an a container, and each container set at upper and lower stages is elongated linearly at right angles to each unit.</p> |
