<p>PURPOSE:To prevent hot gas generated by a breaker from directly striking against a current transformer and badly influencing it, in a gas insulation switching device which has the breaker housed in an insulation gas-filled tank and the current transformer located above the breaker. CONSTITUTION:A primary circuit conductor located above a breaker 2 in a cutoff tank 14 is extended to form an isolated section 23 which is parallelly isolated from the breaker 2 and is parallel with the center of an axis of the breaker 2. A current transformer 3 is installed in the isolated section 23.</p> |
