Abstract：
 The invention relates to a flexible Roe coil for pulse current measurement, pertaining to the high-pressure measurement technology in the art of electricians. The invention includes a casing, a metal shielding layer, a flexible frame, a coil, a conductive core wire and an integrator. The casing, metal shielding and flexible frame are relatively fixed as concentric rings from outside to inside and one side of the ring is provided with an opening. The coil is wound on the flexible frame, the conductive core wire is buried in the flexible frame and the coil is connected with the integrator. The the flexible Roe coil of the invention improves the prior rigid casing and coil frame into a flexible structure and the flexible coil is designed to have an opening with the head end connected with the tail end through a connector, so that Roe coil has the advantages of good flexibility, easy installation and dismantling, compact and portable, simple and convenient installation, which is applicable to field use. Compared with the prior rigid Roe coil, the invention greatly expands the application range of Roe coil.
