<p>PROBLEM TO BE SOLVED: To ensure and simplify the mounting by forming a first current detecting part by winding a coil on an iron core of annular body, making the annular body openable and closable, so that a high voltage distribution line is inserted into the iron core to detect the current value. SOLUTION: A first current detecting part 2 is formed of iron cores 21, 22 of halved annular bodies. The iron cores 21, 22 are supported by an opening and closing support part 23 in such a manner as to be openable and closable, and a high-tension line within a voltage receiving and transforming equipment is inserted thereto to directly detect the current by magnetic bonding. A second current detecting part 3 is formed by interlinking a short-circuit line 27 short- circuiting the leading wire of the winding of the first current detecting part 2 with the iron core, and winding a winding on the iron core, and it detects the current of the high-tension line on the basis on the current induced in the winding. The iron cores 21, 22 are opened to both sides, and a holder installed to the high-tension line is inserted thereto, and then fixed by a fixing band 24. A current sensor 1 can be surely and easily mounted in an optional position of the high-tension line while preventing the displacement and dropping-out.</p> |
