Abstract

An application method for a coupling-releasing shield cable, configures a new coupling-releasing shield cable by adding an encircling insulative conductive coupling-releasing shield layer (2) between an insulative wire cable core (1) and an outer shield layer (4) of a common shield cable, the coupling-releasing shield layer (2) is connected to a control loop common port (COM) so that capacitance coupling of the outer shield layer (4) and the inner insulative wire cable core (1) is cut. And the new coupling-releasing shield layer (2) forms a new larger distribution capacitance together with the insulative wire cable core (1) connected with a control loop and the grounding outer shield layer (4), respectively, a coupling-releasing and filtering work state is showed on the controlled loop, thereby, the distribution capacitance can be converted into a good action of increasing antijamming ability of the loop.

Description

technical field [0001] The technology of the invention belongs to the field of electrical control, and relates to a special shielded cable and a connection method capable of simultaneously effectively suppressing system and loop electromagnetic interference and transmission channel coupling interference. Background technique [0002] In order to ensure that the large-scale control system can still operate in the case of reduced insulation or grounding at one point, the DC power supply of the control system usually adopts the system wiring method of indirect grounding. For anti-interference, control cables often use shielded cables, and because of the large distributed capacitance of general-purpose shielded control cables, the shielding layer is designed according to the direct grounding method. This cable and wiring method is used in the above-mentioned large-scale control system of suspension power supply, and its large distributed capacitance will inevitably provide a cou...
