<p>PROBLEM TO BE SOLVED: To miniaturize a gas insulated switching apparatus for receiving power which comprises a circuit breaker element, a cable head element and a bus disconnector element. SOLUTION: A container 25 of the bus disconnector element Ebs is connected to an upper part on a back face of a container 23 of the circuit breaker element Ecb. The cable head element Ech disposed under the bus disconnector element Ebs is directly connected to the back of the circuit breaker element Ecb. The cable head element is lowered and can be disposed under the bus disconnector element by using an electrostatic capacity voltage measuring instrument, whose detecting electrodes are disposed in a container of the cable head element, as a line voltage measuring instrument. An arrester element can be removed by accommodating an arrester LA in the container of the cable head element. The cable head element can be directly connected to the circuit breaker element.</p> |
