PURPOSE:To make the device compact and reduce the installation space by use of a current transformer with disconnecting switch. CONSTITUTION:In a current transformer with disconnecting switch, a current transformer 31 connected in series with a breaker 14 is fixed on a rotary table 24 rotated by an operating unit 29, a rotary disconnection blade 39 is fitted to the head of the current transformer 31, the blade 39 is opened and closed by means of the operating unit 29, and a fixed contact 44 which contacts and parts from the blade 39 is fitted to the head terminal 42 of a support insulator for fixing a lead-in bus. Compared with the case where a conventional separate type disconnecting switch is use, this constitution simplifies the structure of the whole device, makes the device compact, and largely reduces the installation space. |
