A coupled signal transmitter

Abstract

The invention provides a coupling signal transmitting device, comprising a handleless upper clamp device, a handle lower clamp device and a driving gear device with a handle, the handleless upper clamp device and the handle lower clamp device are semicircular Structure, the driving gear device with handle is fixed on the tail of the handleless upper pincer device, the tail of the handleless upper pincer device and the handle lower pincer device are combined through positioning pins and positioning tables of the two shells. The handleless upper pincer device includes a handleless pincer shell, an upper half magnetic core, an excitation coil 1, an upper magnetic conducting sleeve, and an upper stroke guide rail; the described lower pincer device with a handle includes a handle pincer shell 1. Lower half magnetic core, excitation coil 2. Lower magnetic sleeve, lower stroke guide rail; can effectively solve the problem that the accuracy and effectiveness of the test are affected by the impact deformation of the magnetic core and the leakage of the magnetic induction line.

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...
