The invention discloses an R pin type insulator replacement tool for electrifying indirect operation of a transmission line. The R pin type insulator replacement tool comprises a hook body (1) at the top end, a connector (2) at the middle and an operation rod (3) at the lower end, wherein the hook body (1) is connected with one end of the connector (2) in a sleeving manner, the other end of the connector (2) is provided with a fastening hole a (8), the axial lead of the fastening hole a (8) is vertical or parallel to the hook head of the hook body (1), the upper end of the operation rod (3) is provided with a fastening hole b (9), and the connector (2) is connected with the operation rod (3) by inserting a turning buckle into the fastening hole a (8) and the fastening hole b (9). The R pin type insulator replacement tool has the advantages of simpleness in disassembly and convenience for replacement, and ensures that an R pin type insulator of the transmission line is replaced more safely and rapidly during electrifying indirect operation.
Description
technical field [0001] The invention belongs to the technical field of the electric power industry, and the technical field of an R-pin type insulator replacement tool device device structure for replacing an R-pin insulator of a transmission line through live indirect operation. Background technique [0002] One of the most common defect handling in high-voltage transmission lines is the replacement of insulators, which can carry out blackout work and live work. In daily work, the replacement of insulators in live work accounts for a large proportion. At present, there are usually two types of insulator connection fittings on the line in operation, W pin and R pin. When replacing the insulator with power on, the W pin insulator can be replaced indirectly by using a six-purpose device equipped with an insulating operating rod, or by using the equipotential operation method. The R-pin insulator must be replaced by the equipotential operation method, and the staff needs to en...
