Embodiment 1

[0039] In a typical embodiment of the present invention, such as Figure 1-Figure 4 As shown, a control cable terminal identification system is proposed, including a core wire terminal identification device, a measuring device, and several grounding leads 8 for connecting the core wire terminal identification device to the grounding grid.

[0040] Among them, there are several core wire terminal identification devices installed on the local equipment side, and one measuring device is installed on the side of the centralized control cabinet. A single core wire terminal identification device corresponds to a single core wire to be calibrated one by one. The core wire terminal identification device is connected to one end of the corresponding core wire, and the other ends of several core wires to be calibrated are collectively connected to the measuring device.

[0041] Specific as figure 1 As shown, the core wire terminal identification device is composed of the first plug 1, t...

Embodiment 2

[0070] In another typical embodiment of the present application, a method for using a control cable terminal identification system as described in Embodiment 1 is provided, specifically as follows:

[0071] Step 1: Calibration personnel sort out the core wires that need to be calibrated, and according to the wiring diagram, customize the cable numbers one by one as the number used in this embodiment, such as customizing the NL45853 core wire in the wiring diagram as # 1 core wire, make a comparison table;

[0072] Step 2: Insert the core wires into the corresponding actual number plates one by one at the equipment terminals on each local equipment side, and insert them into the core wire contact socket 6 in the core wire terminal identification device to ensure good metal contact of the core wires;

[0073] Wherein, the number of the actual number plate is determined according to the number plate 2 in the core wire terminal identification device corresponding to the core wire;...

Description

technical field [0001] The invention relates to the technical field of power system calibration detection technology, in particular to a control cable terminal identification system and method. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] In the construction, transformation and operation and maintenance of modern power plants, substations / distribution stations, chemical plants, municipal buildings and other projects, a distributed control system (multiple local devices, a centralized control center) is essential, and a large number of control cables will be used Or secondary wire cores, it is inevitable to carry out a large number of centralized calibration lines during construction, renovation and operation and maintenance. Engineers need to check dozens or even hundreds of unidentifiable core wires one by one to confirm the wiring at both ends...
