Description

Technical Field

[0001] This utility model relates to the field of control cabinet technology, specifically to a modular power plant control cabinet wiring structure with strong and weak current isolation. Background Technology

[0002] In the field of power plant automation control, with the increasing integration of equipment and operational requirements, problems such as electromagnetic interference between strong and weak electrical signals, maintenance difficulties caused by messy wiring, and insufficient system scalability are becoming increasingly prominent. Traditional control cabinets often suffer from signal distortion, equipment malfunction, and even safety hazards due to the mixed wiring of strong electrical (such as power circuits) and weak electrical (such as control signals and communication lines). At the same time, non-modular design requires the replanning of a large number of lines when adding new equipment or making modifications, increasing downtime and costs. Against this background, modular power plant control cabinet wiring structures have emerged.

[0003] The existing modular power plant control cabinet wiring structure with strong and weak current isolation is difficult to separate the strong current circuits from the weak current circuits through physical partitioning, cannot effectively achieve electromagnetic shielding, and has poor anti-interference effect, thus failing to guarantee the safe operation of the system. Therefore, it is necessary to provide a modular power plant control cabinet wiring structure with strong and weak current isolation to solve the above technical problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To overcome the shortcomings of existing technologies, a modular power plant control cabinet wiring structure with strong and weak current isolation is proposed to solve the problems of difficulty in physically separating strong and weak current circuits, ineffective electromagnetic shielding, poor anti-interference effect, and inability to guarantee the safe operation of the system.

[0006] (II) Technical Solution

[0007] This utility model is achieved through the following technical solution: This utility model proposes a modular power plant control cabinet wiring structure with strong and weak current isolation, including a power plant control cabinet body. A left electromagnetic shielding metal partition is fixedly installed between the left side walls of the inner cavity of the power plant control cabinet body, and a right electromagnetic shielding metal partition is fixedly installed between the right side walls of the inner cavity of the power plant control cabinet body. Several horizontal plates are evenly fixedly installed from top to bottom between the left and right electromagnetic shielding metal partitions. A wire receiving box is fixedly installed at the bottom of each horizontal plate. Several first wiring rod mechanisms are evenly fixedly installed from left to right between the front and rear walls of the inner cavity of each wire receiving box. Several second wiring rod mechanisms are evenly fixedly installed between the front and rear walls of the inner cavity of the power plant control cabinet body and to the left of the left electromagnetic shielding metal partition. Several third wiring rod mechanisms are evenly fixedly installed between the front and rear walls of the inner cavity of the power plant control cabinet body and to the right of the right electromagnetic shielding metal partition.

[0008] Furthermore, each of the second wiring pole mechanisms is located to the left of the corresponding wire receiving box, and the spacing between the second wiring pole mechanisms and the adjacent wire receiving boxes decreases sequentially from top to bottom.

[0009] Furthermore, each of the third wiring pole mechanisms is located to the right of the corresponding wire receiving box, and the distance between the third wiring pole mechanisms and the adjacent wire receiving box decreases sequentially from top to bottom.

This structure also improves system stability and maintenance efficiency, adapts to the needs of intelligent upgrades in power plants, and has become an important development direction in the current industrial control field.

Several first wiring rod mechanisms 6 are evenly fixedly installed from left to right between the front and rear walls of the inner cavity of each wire receiving box 5. Several second wiring rod mechanisms 7 are evenly fixedly installed between the front and rear walls of the inner cavity of the power plant control cabinet body 1 and to the left of the left electromagnetic shielding metal partition 2. Several third wiring rod mechanisms 8 are evenly fixedly installed between the front and rear walls of the inner cavity of the power plant control cabinet body 1 and to the right of the right electromagnetic shielding metal partition 3.

[0021] Through the cooperation of the left electromagnetic shielding metal partition 2, the right electromagnetic shielding metal partition 3, the wire receiving box 5, the first wiring pole mechanism 6, the second wiring pole mechanism 7, and the third wiring pole mechanism 8, the high-voltage and low-voltage wires can be guided and arranged separately. Under the action of the left electromagnetic shielding metal partition 2 and the right electromagnetic shielding metal partition 3, the high-voltage circuit and the low-voltage circuit are separated by physical partitioning, effectively achieving electromagnetic shielding, reducing signal interference, and ensuring the safe operation of the system. This structure also improves system stability and maintenance efficiency, meets the needs of power plant intelligent upgrading, and has become an important development direction in the current industrial control field.
