In addition, in the description with reference to the drawings, the same mark in different drawings represents the same element.

[0027] According to a first aspect of the present disclosure, a control cabinet for a hydropower station unit is provided, referring to Figures 1 to 5As shown, the hydropower station unit includes multiple groups of generator sets, and the control cabinet includes a cabinet body 1 and a control module 3. A plurality of functional areas 110 are arranged inside the cabinet body 1, and at least some of the functional areas 110 are provided with identification marks 2 to distinguish each functional area 110; at least some of the functional areas 110 are each provided with a control module 3, and the number of the control modules 3 is the same as the number of the generator sets and they are signal-connected one-to-one. The control module 3 includes a control button 310 and a signal transmission component 320. The control button 310 is signal-connected with the corresponding generator set through the signal transmission component 320 to control the start and stop of the corresponding generator set and the opening and closing of the water inlet gate of the generator set.

[0028] Through the above technical solution, that is, the control cabinet of the hydropower station unit provided by the present invention, the control cabinet is provided with multiple functional areas 110 inside the cabinet body 1, and at least some of the functional areas 110 are provided with identification marks 2. In this way, since the identification marks 2 are provided on the functional areas 110, a clear visual distinction can be formed, which is convenient for operation and maintenance personnel to distinguish each functional area 110, so as to reduce the possibility of misoperation of the operation and maintenance personnel during the operation of the control cabinet, reduce the risk of shutdown of multiple groups of generator sets, such as non-maintenance generator sets, and emergency door drop operation of the water inlet gate of the non-maintenance generator sets due to misoperation, and improve the safety of the hydropower station units.

[0029] In some embodiments, reference Figures 1 to 5 As shown, a function panel 4 may be provided in the function area 110, a control button 310 may be provided on the function panel 4, and an identification mark 2 may be provided on the function panel 4, and the identification mark 2 may include at least one of a coating mark, a color mark, a pattern mark or a text mark provided on the function panel 4.

In this way, each English letter corresponds to a group of generator sets, which makes it easier for operation and maintenance personnel to better distinguish between the various function panels 4.

[0031] Of course, the specific embodiments of the above-mentioned identification mark 2 are exemplary. In other embodiments not shown in the figure, the above-mentioned identification mark 2 can also be, for example, a color mark set on the function panel 4. For example, different function panels 4 can be sprayed with different colors to distinguish different function panels 4, or, in other embodiments not shown in the figure, pattern marks such as icons or symbols of different shapes can also be set on the function panel 4 to facilitate operation and maintenance personnel to better distinguish each function panel 4, or, in other embodiments not shown in the figure, different coatings can be sprayed on different function panels 4 to form a coating mark. In this way, not only can the coating mark provide intuitive visual cues, but the coating can also play a protective role. The present disclosure is not limited to this.

[0032] In addition, the above-mentioned identification mark 2 is not limited to the above-mentioned coating mark, color mark, pattern mark or text mark. In other embodiments, different indicator lights or different unit prompt information can be displayed on a display screen to form an identification mark 2. By way of example, indicator lights of different colors can be set on the function panel 4, such as light-emitting diodes or LED lights to distinguish each function panel 4, or a display screen can be set on the function panel 4 to display different unit prompt information on different function panels 4 through the display screen to distinguish each function panel 4. The present disclosure does not specifically limit such deformation methods, and those skilled in the art can design adaptively according to actual application requirements.

[0033] In addition, it should be noted that those skilled in the art can adaptively set one or more of the above-mentioned coating identification, color identification, pattern identification, text identification, indicator light or display screen on the functional panel 4 according to actual application requirements. The present disclosure does not make specific limitations on this. The purpose is to be able to form an intuitive visual distinction on the functional panel 4, which helps operation and maintenance personnel to quickly identify and operate the functional panel 4 of the corresponding generator set, thereby reducing the possibility of misoperation.

[0036] It should be noted that the signal transmission between the control button 310 and the corresponding generator set through the signal transmission component 320 is a conventional technology known in the art. For example, after the operation and maintenance personnel presses the control button 310, the button action signal can be transmitted to the water inlet gate control panel of the corresponding generator set through, for example, hard wiring, to achieve, for example, emergency door closing operation. At the same time, the button action signal can be transmitted to the input module of the main control LCU of the corresponding generator set through, for example, the optical terminal box 325 to execute the emergency shutdown process of the unit. The main control LCU door closing command of the generator set is transmitted through the input of the remote I / O control panel set in the water inlet hydraulic hoist room. The module hard-wired circuit performs the door-dropping operation, and the key action can be transmitted to the protection control panel of the corresponding generator set through, for example, the optical terminal box 325 to execute the water machine protection emergency shutdown process. The water machine protection door-dropping command is hard-wired to the door-dropping circuit of the gate control panel through the remote I / O control panel optical terminal signal output circuit set in the water inlet hydraulic hoist room to realize the emergency door-dropping operation.
