[0018] Beneficial effects of the present invention:

[0019] The present invention provides a control and protection method for an electrical system. The electrical cabinet shell is provided to protect the internal structure of the electrical system. A sliding plate and a waterproof pad are provided at the same time. A limiting rod and an abutting spring are used to achieve abutment and limitation of the sliding plate and the waterproof pad, so that the sliding plate and the waterproof pad will not affect the closing of a closed door, and can abut against one side of a waterproof groove, so as to achieve preliminary waterproofing of the closed door. At the same time, a plug-in baffle and a plug-in slot block are provided on the door gap of the closed door, so that the plug-in baffle is inserted into the inside of the plug-in slot block for waterproofing. At the same time, the design of the sliding rod and the reset spring on the door can ensure that the plug-in baffle can be freely extended and retracted, so that the waterproofing of the door gap can be achieved after the closed door is closed without affecting the opening and closing of the closed door. The combination of the two can achieve the basic waterproofing function of the electrical cabinet body, and well reduce the influence of rainwater on the electrical cabinet body.

[0020] The present invention provides a control and protection method for an electrical system. By setting a trigger structure, after the closed door is closed, the abutting slider is abutted and compressed, and then the abutting slider drives the limit trigger block to move and contact the trigger switch. At this time, the trigger switch will turn off the lighting lamp. At the same time, the abutting slider will compress the auxiliary spring in this process, and then after the closed door is opened, the auxiliary spring will bounce the abutting slider and the limit trigger block away from the trigger switch. At this time, the trigger switch starts to turn on the lighting lamp for lighting, so that the maintenance personnel can light up in time after opening the main body of the electrical cabinet.

[0021] The present invention provides a control and protection method for an electrical system. By setting a connecting rod, the closing of the closing door will synchronously drive the sliding top block to move and then lift the connecting sliding rod and the round bead bottom block. Furthermore, the sliding plate drives the insertion rod to rise and then snap into the inside of the fixed main body block. At this time, the fixed main body block is limited and fixed and cannot be detached. Similarly, after the closing door is opened, the sliding top block leaves, and then the round bead bottom block descends to drive the sliding plate to descend synchronously. At this time, the insertion rod no longer inserts into the inside of the fixed main body block, and at this time, the fixed main body block can be detached. Description of the Drawings

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] The following gives specific embodiments.

[0037] Please refer to Figures 1-10 , the present invention provides a control and protection method for an electrical system, including the following steps:

[0038] S1: First, a variety of control switches and individual modules and components are required in the control structure of the electrical system; at the same time, these switches and components usually need to be connected using the electrical cabinet main body; at the same time, KB0 is used; that is, a combination of an air switch and thermal protection and a contactor; KB0 can perform functions such as thermal protection, overvoltage protection, and leakage protection of the electrical system.

[0039] S2: In the electrical system; when the operation of the system is abnormal; and then the electrical system experiences overheating, overvoltage, and leakage phenomena; KB0 can detect this series of problems in a timely manner; and then timely turn off the operation of some switches of the electrical system; thereby reducing the occurrence of accidents.

[0040] S3: After KB0 operates; maintenance personnel can open the electrical cabinet main body for internal maintenance; and then detect the problems that occur in the electrical system; at the same time, maintenance personnel can perform module and component maintenance; and at the same time reset KB0.

[0041] Furthermore, as Figure 2 ,Figure 3 , Figure 4 , Figure 8 and Figure 9 As shown in the figures, it includes an electrical cabinet housing 1; a hinge 4 is installed on the side of the electrical cabinet housing 1; the hinge 4 is fixedly connected to a first closing door 5 and a second closing door 6 respectively; waterproof grooves 10 are provided on one side of the first closing door 5 and the second closing door 6; a plug-in block 11 is fixedly connected to one side of the second closing door 6; a fixed door nose 7 is fixedly connected to the other side of the second closing door 6; a limit track block 12 is fixedly connected to one side of the first closing door 5; a door upper slide bar 33 is fixedly connected to the inner wall of the limit track block 12; a plug-in baffle 13 is slidably connected to the outer wall of the door upper slide bar 33; the plug-in baffle 13 is fixedly connected to a return spring 34 through the limit track block 12; a sliding groove 9 is provided on the other side of the first closing door 5; a sliding door nose 8 is fixedly connected to the side of the plug-in baffle 13 through the first closing door 5; a limit rod 31 is fixedly connected to the inner wall of the electrical cabinet housing 1; a sliding plate 20 is slidably connected to the outer wall of the limit rod 31; the sliding plate 20 is slidably connected to the inner wall of the electrical cabinet housing 1; the sliding plate 20 is fixedly connected to a contact spring 32 through the electrical cabinet housing 1; a waterproof pad 21 is fixedly connected to the side of the sliding plate 20; a mounting plate 2 is fixedly connected to the outer wall of the electrical cabinet housing 1; a rain shield 3 is fixedly connected to the top of the electrical cabinet housing 1. During operation, the rotation and closing of the first closing door 5 and the second closing door 6 can be realized through the hinge 4. At the same time, the closing of the first closing door 5 and the second closing door 6 will squeeze the sliding plate 20 and the waterproof pad 21, causing the sliding plate 20 to slide on the outer wall of the limit rod 31 and simultaneously squeezing the contact spring 32 until the contact spring 32 will re-contact the squeezed sliding plate 20 and the waterproof pad 21 into the waterproof groove 10 after the first closing door 5 and the second closing door 6 are closed. At the same time, during the closing process of the first closing door 5 and the second closing door 6, it is necessary to pull the sliding door nose 8, so that the sliding door nose 8 drives the plug-in baffle 13 to slide on the door upper slide bar 33, synchronously squeezing the return spring 34 until the first closing door 5 and the second closing door 6 are completely closed, and then release the sliding door nose 8. At this time, the return spring 34 will pop out and reset the plug-in baffle 13 until the plug-in baffle 13 is inserted into the plug-in block 11.

[0042] Furthermore, as shown in Figure 5 and Figure 10As shown in the figure, a lighting lamp 25 is installed on the inner top wall of the electrical cabinet housing 1; a trigger main body 24 is fixedly connected to the inner top wall of the electrical cabinet housing 1; a trigger switch 38 is installed on the inner surface wall of the trigger main body 24; the trigger switch 38 is electrically connected to the lighting lamp 25; a contact slider 35 is slidably connected to the inner surface wall of the trigger main body 24; a limit trigger block 36 is fixedly connected to the outer surface wall of the contact slider 35; a connecting rod 39 is fixedly connected to the side surface of the contact slider 35; the connecting rod 39 penetrates through the trigger main body 24; the connecting rod 39 is slidably connected to the trigger main body 24; the contact slider 35 is fixedly connected to an auxiliary spring 37 through the trigger main body 24. During operation, in the process of closing the first closing door 5 and the second closing door 6, the first closing door 5 and the second closing door 6 will abut against the side surface of the contact slider 35, so that the contact slider 35 can slide on the inner surface wall of the trigger main body 24, and at the same time, the limit trigger block 36 abuts against the trigger switch 38, thereby closing the trigger switch 38 to turn off the lighting lamp 25. At the same time, in this process, the contact slider 35 will drive the connecting rod 39 to slide, and synchronously compress the auxiliary spring 37. To sum up, when the first closing door 5 and the second closing door 6 are opened, the compressed auxiliary spring 37 will eject the contact slider 35 and the limit trigger block 36. At this time, the limit trigger block 36 is separated from the trigger switch 38, thereby enabling the trigger switch 38 to start the lighting lamp 25 for lighting.

[0043] Further, as Figure 4 , Figure 6 , Figure 7 and Figure 10As shown, one end of the connecting rod 39 is fixedly connected with a sliding top block 23; the inner wall of the electrical cabinet housing 1 is fixedly connected with a module fixing main body 19; a plugging slot 22 is formed on the side surface of the module fixing main body 19; a sliding frame 28 is slidably connected to the inner wall of the module fixing main body 19; a plugging rod 29 is fixedly connected to the top of the sliding frame 28; a connecting sliding rod 26 is fixedly connected to the inner wall of the sliding frame 28; the connecting sliding rod 26 passes through the module fixing main body 19 and is fixedly connected with a round bead bottom block 27; the round bead bottom block 27 abuts against the sliding top block 23; a KB0 main body 15 is arranged on the side surface of the module fixing main body 19; a KB0 wiring board 16 is electrically connected to the side surface of the KB0 main body 15; an electrical system control switch 17 is arranged on the side surface of the module fixing main body 19; an electrical system wiring board 18 is electrically connected to the bottom of the electrical system control switch 17; a display screen 14 is arranged on the side surface of the module fixing main body 19; a fixing main body block 30 is fixedly connected to the side surface of the display screen 14; the fixing main body block 30 is respectively fixedly connected to the side surfaces of the KB0 main body 15 and the electrical system control switch 17; the fixing main body block 30 is slidably connected to the inner wall of the module fixing main body 19; the fixing main body block 30 is slidably connected with the plugging rod 29. During operation, after the first closing door 5 and the second closing door 6 are opened, the connecting rod 39 drives the sliding top block 23 to move, and then the round bead bottom block 27 moves and falls along the upper end surface of the sliding top block 23. At this time, the sliding frame 28 will be affected by gravity, causing the sliding frame 28 to descend and drive the plugging rod 29 to descend. At this time, the plugging rod 29 disengages from the fixing main body block 30, and the display screen 14, the KB0 main body 15 and the electrical system control switch 17 can be conveniently detached. Similarly, when the first closing door 5 and the second closing door 6 are closed, the sliding top block 23 moves, and then the connecting sliding rod 26 and the round bead bottom block 27 are jacked up. At this time, the plugging rod 29 can be inserted into the bottom of the fixing main body block 30, thereby limiting and fixing the fixing main body block 30.

[0044] Working principle: The rotation and closing of the first closing door 5 and the second closing door 6 can be achieved through the hinge 4. At the same time, the closing of the first closing door 5 and the second closing door 6 will squeeze the sliding plate 20 and the waterproof pad 21, causing the extrusion sliding plate 20 to slide on the outer wall of the limit rod 31 and simultaneously squeezing the abutting spring 32 until the abutting spring 32 will re-abut the extrusion sliding plate 20 and the waterproof pad 21 against the inside of the waterproof groove 10 after the first closing door 5 and the second closing door 6 are closed. At the same time, during the closing process of the first closing door 5 and the second closing door 6, it is necessary to pull the sliding door nose 8, so that the sliding door nose 8 drives the plugging baffle 13 to slide on the door slide bar 33, synchronously squeezing the reset spring 34 until the first closing door 5 and the second closing door 6 are completely closed, then release the sliding door nose 8. At this time, the reset spring 34 will pop out and reset the plugging baffle 13 until the plugging baffle 13 is inserted into the inside of the plugging block 11. During the closing process of the first closing door 5 and the second closing door 6, the first closing door 5 and the second closing door 6 will abut against the side of the abutting slider 35, enabling the abutting slider 35 to slide on the inner wall of the trigger body 24, and at the same time causing the limit trigger block 36 to abut against the trigger switch 38, thereby closing the trigger switch 38 to turn off the lighting lamp 25. At the same time, during this process, the abutting slider 35 will drive the connecting rod 39 to slide, synchronously squeezing the auxiliary spring 37 to compress. To sum up, when the first closing door 5 and the second closing door 6 are opened, the compressed auxiliary spring 37 will pop out the abutting slider 35 and the limit trigger block 36. At this time, the limit trigger block 36 is separated from the trigger switch 38, thereby causing the trigger switch 38 to start the lighting lamp 25 for lighting. After the first closing door 5 and the second closing door 6 are opened, the connecting rod 39 drives the sliding top block 23 to move, so that the sliding top block 23 no longer abuts against the round ball bottom block 27. At this time, the sliding frame 28 will be affected by gravity, causing the sliding frame 28 to descend and drive the plugging rod 29 to descend. At this time, the plugging rod 29 is separated from the fixed main body block 30, and the display screen 14, the KB0 main body 15, and the electrical system control switch 17 can be detached conveniently. Similarly, when the first closing door 5 and the second closing door 6 are closed, the sliding top block 23 moves, thus jacking up the connecting slide rod 26 and the round ball bottom block 27. At this time, the plugging rod 29 can be inserted into the bottom of the fixed main body block 30, thereby limiting and fixing the fixed main body block 30.

[0045] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
