<p>PURPOSE:To dispense with a special purpose casing and to simplify the constitution by enclosing a disconnector for a lightning arrestor into a bushing casing at the lower part of a line side bushing. CONSTITUTION:Beside a circuit breaker 1 a bus side bushing 3, a bus side earth switch 7, a disconnector 9, a checking earth switch 8, a checking earth switch 8, a disconnector 9, a line side earth switch 6, a line side bushing 2, a disconnector 5 for a lightning arrestor, a disconnector 9, a checking earth switch 8, a checking earth switch 8, a disconnector 9, a disconnector 5 for a lightning arrestor, a line side bushing 2, a line side earth switch 6, a disconnector 9, a checking earth switch 8, a checking earth switch 8, a disconnector 9, a bus side earth switch 7 and a bus side bushing 3 are rectilinearly arranged in parallel with the circuit breaker 1. A lightning arrestor 4 is arranged beside the disconnector 5 for the lightning arrestor, which is enclosed into a bushing casing 11 at the lower part of a line side bushing 2. The structure of the disconnector 5 for the lightning arrestor can thereby be simplified.</p> |
