Coupling signal transmitting device

Abstract

The invention provides a coupling signal transmitting device, which comprises a handle-free upper pincerlike device, a handle-equipped lower pincerlike device and a handle-equipped driving gear device, wherein the handle-free upper pincerlike device and the handle-equipped lower pincerlike device are both semicircular structures, the handle-equipped driving gear device is fixed at the tail part of the handle-free upper pincerlike device, and the tail parts of the handle-free upper pincerlike device and the handle-equipped lower pincerlike device are combined together through a positioning pin and the positioning table surfaces of the two shells. The handle-free upper pincerlike device comprises a handle-free pincerlike shell, an upper half magnetic core, a first magnet exciting coil, an upper magnetic sleeve and an upper stroke guide rail; and the handle-equipped lower pincerlike device comprises a pincerlike shell with the handle, a lower half magnetic core, a second magnet exciting coil, a lower magnetic conductive sleeve and a lower stroke guide rail. The problem that the test accuracy and effectiveness are influenced by impact deformation and magnetic induction line leakage of the magnetic core can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of power system devices, in particular to a coupling signal transmitting device. Background technique [0002] At present, with the development of the city, the overhead line can no longer meet the power supply demand of the power system for the city, and the underground cable has the characteristics of concealment and safety, and has already dominated the urban power supply network. [0003] As the number of underground cables increases, the number of faults also increases, often requiring a lot of work such as path query and cable identification. [0004] For the live cable, since the core part of the cable cannot be directly contacted, the coupling method is usually used to couple the signal to the inside of the cable, and the entire cable has a coupled input test signal, so as to complete the path query and cable identification. [0005] The most commonly used coupling for transmitting signals is a clam...
