Description

Technical Field

[0001] The invention relates to an electrical cabinet, in particular to a wiring method for an electrical cabinet. Background Art

[0002] The low-voltage electrical cabinet of the Harmony electric locomotive mainly integrates a DC110V distribution single-pole circuit breaker, contactors for controlling the start and stop of auxiliary equipment such as traction fans, compressors, water pumps, and oil pumps, and three-phase circuit breakers for overcurrent and short-circuit protection, as well as contactors for auxiliary circuits, in-depot power supplies and other devices, grounding detection devices and other devices. It is a switch cabinet for the opening, closing, control and protection of various equipment on the electric locomotive. It has many connecting devices and the number of cables entering and leaving the cabinet can reach thousands.

[0003] There are two common modes of traditional wiring tables currently used: one is that the wiring table is arranged in order of wire number, and the other is that the wiring table is arranged in order of point positions.

[0004] 1. When the wiring table is arranged by wire size, the wiring operator first holds a wire number and searches the wiring table for the wiring device code and wiring point according to the wire number sequence. Then, the operator locates the corresponding device installation position and the precise wiring position of the device point in the panel cabinet. Repeat this process of finding the wiring location and then wiring for each cable.

[0005] 2. When the wiring diagram is arranged in point order, the wiring diagram is arranged in the order in which the components are actually installed. The wiring technician does not need to confirm the component installation location. He only needs to confirm the wire number of the precise wiring location of the component point, then find the wire number from the bundle and connect it to the corresponding location. Repeat this process for each cable, first find the corresponding cable, then connect it.

[0006] When wiring diagrams are arranged by wire number, operators must repeatedly search through the diagram while verifying the actual location of components. This time-consuming process can easily lead to issues like looking at the serial number, missing a number, or searching repeatedly to find the corresponding wire number. When wiring diagrams are sorted by point, while operators don't need to verify the actual location of components, they must repeatedly count the wires, which can easily lead to problems like tangled cables and missing wire numbers. Regardless of the traditional wiring method, the significant searching effort required leads to low efficiency, fatigue, and the potential for quality issues like incorrect and missed connections to go undetected. After wiring is complete, existing wiring diagrams cannot confirm whether all required cables for a particular component have been connected. Checking for incorrect connections requires backtracking, making post-process self-inspection and cross-checking inconvenient, leading to a high rate of rework in the panel wiring process. These issues demonstrate that existing wiring methods are not adequate for wiring electrical panels with a high number of terminations. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide an electrical cabinet wiring method to improve the efficiency and quality of wiring.

[0008] To solve the above technical problems, the technical solution of the present invention is: a wiring method for an electrical cabinet, wherein the electrical cabinet is provided with several rows of connection components, each row of connection components including several connection devices arranged in a line, and the wiring method comprises the following steps: (1) Prepare a visual wiring table for the connection components and a bundle table for the connection devices; the visual wiring table includes several columns of connection device wiring tables, and the positions of the connection device wiring tables correspond one-to-one to the positions of the connection devices in each row of the connection components in the electrical cabinet; the connection device wiring table in each column includes a component position code located in the middle position, a wiring requirement located below the component position code, an upper cable number located above the component position code, an upper wiring point corresponding to the upper cable number, a lower cable number located below the wiring requirement, and a lower wiring point corresponding to the lower cable number; the upper wiring point and the lower wiring point correspond one-to-one to the actual wiring point of the connection device; (2) Count the cables. Before wiring, operators should count the cables of the connectors to be wired. When dividing the cables, they should divide the cables at the corresponding points into a bundle according to the requirements of the bundle table and count whether the number of cables is consistent with that on the bundle table. (3) Wiring: After completing the cable bundling and terminal crimping work, the cable wiring work needs to be carried out. The operator connects the connectors in the order of their installation positions according to the intuitive wiring table. When wiring, the wiring points of the connectors are connected according to the connector wiring table; (4) Verification: After completing the cable wiring work, it is required to re-check the wiring points to check whether the wiring points of the component cables are correct.

[0009] The principle of this invention is to use an intuitive wiring diagram to perform wiring. Compared with the traditional wiring diagram, the independently designed intuitive wiring diagram simulates the actual wiring position intuitively, presenting the position and wiring requirements in full view of the operator, enhancing visibility and intuitiveness; the intuitive wiring diagram reduces the process of manual thinking and comprehensively improves the process efficiency and quality.

[0010] As an improvement, in step (3), the operator finds the corresponding connector according to the component position code in the intuitive wiring table, and then checks the cable line numbers and corresponding wiring points in the intuitive wiring table one by one.

[0011] As an improvement, the bundle splitting table includes cable numbers and connection points corresponding to the cable numbers, and the connection points in the bundle splitting table correspond one-to-one to the arrangement of the connectors.

[0012] The beneficial effects brought about by the present invention compared with the prior art are: Wiring is performed with the help of an intuitive wiring diagram. Compared with traditional wiring diagrams, the independently designed intuitive wiring diagram simulates the actual wiring position and fully presents the position and wiring requirements to the operator, enhancing visibility and intuitiveness. The intuitive wiring diagram reduces the human thinking process and comprehensively improves the process efficiency and quality. BRIEF DESCRIPTION OF THE DRAWINGS
