[0039] An end ball cavity 805 is provided in the magnetic end ball 804 , a lever connecting cavity 806 is provided in the control lever 8 , and a movable connecting tube 807 is provided for external communication with the control lever 8 . The movable connecting tube 807 is connected to the end ball cavity 805 through the lever connecting cavity 806 .

[0040] A three-level determining seat 808 is fixedly provided on the fixed hanging frame 5, and a cylindrical inner cavity 809 is opened in the three-level determining seat 808.

[0041] A scheduling connection socket 101 is provided on the main control backplane 1, and the main control backplane 1 is connected to the power grid through the scheduling connection socket 101. A panel moving groove 301 is provided on the dial button panel 3, and the dialing protrusion 7 passes through the panel moving groove 301 and extends to the outside of the dial button panel 3.

[0042] A control method for a power grid dispatching control device, the method comprising the following steps:

[0043] Step 1: According to the grid dispatching requirements, set the preset mode to the corresponding preset state button 4;

[0044] Step 2: Press the preset state button 4 to energize the corresponding switching electromagnet 9 in the preset mode;

[0045] Step 3: When the switching electromagnet 9 is energized, the lever 8 is controlled to move the convex portion 7 to complete the dispatching control.

[0046] When the power grid dispatching control device of the present invention is in use, when the toggle protrusion 7 on the two-stage toggle button 6 is toggled, the two-stage toggle button 6 will change on and off, thereby cooperating with the main control backplane 1 to realize the control of power grid dispatching; according to the different allocation of power grid dispatching control under different accidents, different accident handling modes are preset in advance, and correspond one-to-one with the preset status button 4.

[0047] When an accident occurs and a certain mode needs to be quickly entered, the corresponding preset state button 4 can be pressed. When the preset state button 4 is pressed, the corresponding switching electromagnet 9 in the corresponding mode will be energized to generate magnetic force; Figure 7 and Fig. 9 As shown in the figure, after the switching electromagnet 9 generates magnetic force, it cooperates with the magnetic end ball 804 to drive the control lever 8 to rotate around the fulcrum shaft 802. Through the lever principle, the lever convex part 7 is pried to move, so that the lever convex part 7 can move into place quickly, eliminating the need for manual one-by-one manipulation.

[0048] When the control lever 8 is not stuck, when the switching electromagnet 9 generates magnetic force, it will simultaneously attract the magnetic end ball 804 and the secondary magnetic suction cup 505 to move toward the switching electromagnet 9. Therefore, the rotation of the control lever 8 and the movement of the L-shaped bracket plate 502 are carried out simultaneously. While the secondary detection spring 506 moves toward the matching contact piece 507, the matching contact piece 507 swings in the direction away from the secondary detection spring piece 506; the secondary detection spring piece 506 and the matching contact piece 507 do not contact each other. At this time, the warning light 508 is not on, indicating that the button is operating normally.

[0049] When the control lever 8 is stuck, the switching electromagnet 9 generates magnetic force, and the control lever 8 does not rotate. The secondary magnetic suction cup 505 cooperates with the switching electromagnet 9 by magnetic attraction, so that the L-shaped bracket plate 502 drives the secondary detection spring 506 to move toward the matching contact piece 507. At this time, the matching contact piece 507 is stuck and does not rotate because the control lever 8 is stuck, and the matching contact piece 507 is also in a static fixed state. When the secondary detection spring piece 506 moves toward the matching contact piece 507, it will contact and conduct with the matching contact piece 507, and the warning light 508 will light up to alarm.

[0050] After the switching electromagnet 9 is energized, it needs to be maintained for a period of time. The switching electromagnet 9 generates magnetic force, attracting the magnetic end ball 804 to fit and contact it. As the switching electromagnet 9 continues to be energized, it will gradually heat up, and the heat will be transferred into the magnetic end ball 804. Fig. 9 As shown in , the gas in the end ball cavity 805 is heated and expanded, and the gas pressure increases. The gas pressure enters the cylindrical cavity 809 through the movable connecting tube 807, as shown in Fig.10As shown in , the sealing plug shaft 810 is pushed out and moved, so that the three-level bridge plate 811 is connected and contacted with the determination contact piece 813, and the two groups of determination contact pieces 813 are short-circuited and connected to achieve detection; at this time, it means that after the switching electromagnet 9 is energized, the magnetic end ball 804 is in contact with it, and its priority is the highest, and the final determination of the in-place detection is achieved, which can cover the alarm of the warning light 508 and avoid the short circuit connection between the secondary detection spring piece 506 and the matching contact piece 507 due to water ingress and entry of debris, which causes the warning light 508 to misreport.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
