[0035] According to some embodiments of the present invention, the first electrical component 13 is configured as a control transformer.

[0036] In some specific embodiments, the first electrical component 13 can be constructed as a control transformer, that is, a transformer and an air switch. The transformer and the air switch are respectively connected through a high-voltage wire harness. The main function of the transformer is to change the voltage in the electric control cabinet 100 without changing the frequency. The transformer can convert high voltage into low voltage, or convert low voltage electricity into high voltage electricity, so as to facilitate power transmission, distribution and use. In electronic circuits, transformers can be used to match the impedance between different circuits to achieve the effect of maximum power transmission. The transformer can also provide electrical isolation between two circuits to protect equipment safety and personnel safety; the air switch is also called a circuit breaker. It is a protective device that can automatically disconnect the circuit in the event of overload or short circuit. When the current in the circuit exceeds a predetermined value, the air switch will automatically disconnect the circuit to prevent the electric control cabinet 100 from overheating and fire. When the circuit is short-circuited in the electric control cabinet 100, the air switch can quickly cut off the power supply to avoid equipment damage and safety accidents. Through the cooperation of the transformer and the air switch, the reliability and safety of the electric control cabinet 100 during operation are improved.

[0037] According to some embodiments of the present invention, the second electrical component 14 is configured as a current controller 12 .

[0038] In some specific embodiments, the electric control cabinet 100 generally includes a high-voltage part and a low-voltage part. The first electrical component 13 is constructed as a high-voltage part for receiving and processing high-voltage electricity from the power grid, and the second electrical component 14 is constructed as a low-voltage part for distributing electricity to other devices. The second electrical component 14 can be constructed as a current controller 12, that is, a contactor, a relay and an isolation module. The contactor, the relay and the isolation module are connected to the controller 12 through a high-voltage wiring harness and a low-voltage wiring harness respectively. The contactor is an electrical device used to frequently connect and disconnect the main circuit. The contactor can carry a large current through its larger contacts and is suitable for switching the main circuit, that is, controlling the start and stop of the electric control cabinet 100; the contactor can control the start and stop of the electric control cabinet 100 through a smaller control signal (usually from a PLC, a button A relay is an electrically controlled switch used to control a larger load or circuit using a smaller control signal. The relay can amplify weak electrical signals to control a larger current or voltage. The relay can provide electrical isolation to protect the control system from the direct impact of high voltage or high current. The isolation module, or isolator, is used to eliminate interference during signal transmission to ensure signal accuracy and system security. The isolation module can prevent mutual interference between the signal source and the load, especially when there is a voltage difference between the signal source and the load. The isolation module in the electrical control cabinet 100 can effectively suppress electromagnetic interference and radio frequency interference to protect the integrity of the signal in the electrical control cabinet 100.

[0039] According to some embodiments of the present invention, the electric control cabinet 100 further includes: a main circuit breaker 21, which is arranged on the cabinet body 11 and located on a side of the first wiring slot 101 away from the controller 12 in the first direction, and the main circuit breaker 21 is connected to the control transformer.

[0040] In some specific embodiments, a main circuit breaker 21 is also provided in the electric control cabinet 100. The main circuit breaker 21 is provided on the cabinet body 11 and is connected to the control transformer. The main circuit breaker 21 can monitor the current passing through it. When the current exceeds the set safety threshold, it will automatically disconnect the circuit to prevent equipment damage or fire caused by overload. At the same time, when a short circuit occurs in the electric control cabinet 100, the main circuit breaker 21 can respond quickly and immediately disconnect the circuit to prevent damage caused by large current. The main circuit breaker 21 and the controller 12 are respectively located on both sides of the first wiring slot 101 in the first direction. The first wiring slot 101 separates the main circuit breaker 21 and the controller 12. Isolating the main circuit breaker 21 from the controller 12 can reduce the impact of electromagnetic interference on the controller 12 and ensure the accuracy of the control signal and the stability of the system. The main circuit breaker 21 may generate heat when disconnecting a large current. Placing it in a position with sufficient space can help dissipate heat and extend the life of the electric control cabinet 100.

[0041] According to some embodiments of the present invention, the electrical control cabinet 100 also includes: a terminal block 22, which is arranged on the cabinet body 11 and is located on the side of the second electrical component 14 away from the controller 12 in the second direction. The terminal block 22 is arranged away from the controller 12 to reduce electromagnetic interference, and at the same time it is convenient for maintenance personnel to approach the terminal block 22 for wiring or inspection without having to be too close to the controller 12 which may carry high voltage or large current, thereby ensuring the safety of maintenance personnel during maintenance. The terminal block 22 is respectively connected to the first electrical component 13, the second electrical component 14 and the controller 12. The terminal block 22 acts as a bridge, which connects the first electrical component 13, the second electrical component 14, the controller 12 and the external circuit. The terminal block 22 is the key point for connecting the internal and external circuits of the electrical control cabinet 100. Through the terminal block 22, the external line can be safely and reliably connected to the circuit network inside the electrical control cabinet 100, and the internal circuit can be organized and aggregated, which facilitates the management and maintenance of the internal circuit of the electrical control cabinet 100.
