Description

Technical Field

[0001] This utility model relates to an integrated control module, and more particularly to a universal integrated control module for ring main units, belonging to the field of power equipment technology. Background Technology

[0002] Currently, new ring main unit (RNB) equipment manufacturers are constantly emerging in the power equipment industry. The power equipment procured by State Grid Corporation of China and China Southern Power Grid is supplied by multiple equipment manufacturers, and the production processes and technologies of the equipment supplied by each manufacturer are inconsistent.

[0003] The secondary control of the ring main unit has the following two wiring methods:

[0004] 1. Relay wiring method: The disadvantage is that there are many wiring points, making troubleshooting troublesome and requiring professional personnel to complete.

[0005] 2: Add wiring to the controller. The advantage is that there are fewer wiring harnesses and the modular troubleshooting efficiency is relatively faster than the first method. The disadvantage is that if the controller fails, the original module needs to be purchased for replacement, and some single procurement channels are costly and inefficient.

Without changing the original mechanical performance, this module solves the compatibility problem of secondary control modules for ring main unit equipment from various manufacturers. This module is compatible with mainstream ring main unit manufacturers, which can improve the efficiency of power distribution automation operation and maintenance, reduce maintenance costs, and lay a solid foundation for ensuring more stable intelligent power remote control and power operation.

[0056] Furthermore, such as Figure 1 As shown, the power chip controls the power output module to output DC24V-220V DC voltage from the rectifier bridge. After passing through the power chip control power output module, the fixed power output of the functional module is obtained. The input power can be divided into power supply and operating power. This module can realize the power supply to be used separately or in parallel, thus expanding the scope of application.

[0057] In this embodiment, as Figure 1 As shown, the power input includes multiple voltage inputs such as AC / DC 24V, AC / DC 48V, AC / DC 110V, or AC / DC 220V, with multiple input methods, further expanding the scope of application.

Without it, numerous wiring connections, relays, terminals, fuses, and necessary accessories are required. Furthermore, the wiring configuration varies between different cabinet models, making troubleshooting difficult and preventing universal or interchangeable connections. This module significantly reduces wiring complexity, integrates the core control components, and allows for easy replacement, greatly improving maintenance convenience and reducing costs.
