Description

Energy storage mechanism for state switching operation of electrical control system Technical Field

[0001] The present invention relates to the field of switches, and in particular to an energy storage mechanism used for state switching operations of an electrical control system. Background Art

[0002] With the development of current technology, especially in photovoltaic systems, photovoltaic DC switches are used in inverters to control the operating status of multiple core components. The reliability of photovoltaic DC switches is not only related to the smooth operation of the entire photovoltaic system, but also to the stable development of the photovoltaic industry.

[0003] Question 1: For the free tripping device currently on the market for the state switching unit of the electrical control system, when the driving handle (also called the knob) needs to store energy for the tripping device part, it is also necessary to store energy for the internal energy storage element of the driving mechanism part. This results in a relatively large torsional torque of the driving handle. It is not easy for ordinary people to hold the handle to drive energy storage, making the operation of the state switching unit of the electrical control system inconvenient and difficult to operate. One solution is to increase the size of the handle to increase the length of its handle force arm, so as to drive the mechanism to close the switch and store energy more effortlessly. However, this handle occupies a large space and the manufacturing cost of the handle is relatively high.

[0004] Question 2: The free tripping devices for the electrical control system state switching units on the market have the characteristics of rapid shutdown, but they cannot realize the free tripping function. For example, when inspecting and maintaining electrical lines and photovoltaic equipment, if the maintenance personnel need to energize the lines during the inspection process, the driving handle will close the electrical control system state switching unit. At the moment of closing, abnormalities are likely to occur inside the inverter. When abnormalities occur, it is necessary to immediately control the free tripping device to perform a free tripping action on the electrical control system state switching unit to complete the rapid opening. However, because the handle of the electrical control system state switching unit is manually held, the release cannot open the electrical control system state switching unit at the moment of closing, which can easily cause damage to the equipment and harm the personal safety of the operator. In other words, the free tripping process will be restricted by the handle, and the free tripping function cannot be completed.

[0005] Therefore, there is a need for further improvement of the existing energy storage mechanism used for state switching operations of electrical control systems.

[0006] The information disclosed in this background section is only intended to enhance understanding of the overall background of the invention and should not be considered as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

[0081] It should be understood that the accompanying drawings are not necessarily drawn to scale, but rather present simplified representations of various features to illustrate the basic principles of the invention. The specific design features disclosed in the present invention (including, for example, specific dimensions, directions, locations, and shapes) will be determined in part by the specific intended application and use environment.

[0082] In the figures, like reference numbers refer to the same or equivalent parts of the present invention throughout the several figures of the drawing. DETAILED DESCRIPTION

[0083] Reference will now be made in detail to various embodiments of the present invention, examples of which are presented in the accompanying drawings and described below. Although the present invention will be described in conjunction with the exemplary embodiments, it should be understood that this description is not intended to limit the invention to these exemplary embodiments. On the contrary, the present invention is intended to cover not only these exemplary embodiments, but also various alternative forms, modifications, equivalent forms and other embodiments that may be included within the spirit of the invention and the scope defined by the appended claims.

[0084] When an element is referred to as being “on” or “over” another element, the element may be in contact with the other element or intervening elements may also be present.

[0085] The clockwise direction and the counterclockwise direction in the embodiments of the present invention are directions when observing the energy storage mechanism used for state switching operation of the electrical control system from top to bottom.

[0086] The energy storage mechanism for state switching operation of an electrical control system according to an embodiment of the present invention will be described below with reference to FIG. 1 to FIG. 31 .

[0087] As shown in FIG1 , the energy storage mechanism for state switching operation of an electrical control system according to an embodiment of the present invention includes: a housing 1 , an operating component 2 , an actuator 3 , a locking component 4 and an unlocking component 5 .

[0088] The housing 1 is used to carry the operating assembly 2 , the actuator 3 , the locking assembly 4 and the unlocking assembly 5 .

[0089] The operating assembly 2 is mounted on the housing 1 , and the operating assembly 2 includes an energy storage element 21 .

[0090] The actuator 3 is connected to the electrical control system state switching unit.

[0091] The locking assembly 4 is installed to the operating assembly 2 or the actuator 3; the energy storage element 21 connects the operating assembly 2 and the actuator 3, and stores energy by changing the relative position between the operating assembly 2 and the actuator 3. After the relative position of the operating assembly 2 and the actuator 3 is changed to a predetermined position, the operating assembly 2 can be connected to the actuator 3 through the locking assembly 4 and be in a locked state; then the operating assembly 2 is driven to move in the opposite direction, and the actuator 3 is driven to move in the same direction. The operating assembly 2 drives the actuator 3 to reach the restricted position of the operating assembly 2 restricted by the shell 1, thereby causing the actuator 3 to drive the position state of the electrical control system state switching unit to change.

[0092] The unlocking component 5 is installed to the housing 1 or the operating component 2 or the actuator 3; the unlocking component 5 can release the locking state between the operating component 2 and the actuator 3 after receiving the trigger signal, so that the energy stored in the energy storage element 21 is released, and the operating component 2 is restricted by the housing 1 and cannot move in the direction of the force applied to it by the energy storage element 21. Driven by the energy release of the energy storage element 21, the actuator 3 can move in the direction of the force applied to the actuator 3 by the energy storage element 21, thereby driving the position state of the electrical control system state switching unit to change again.

[0093] The embodiment of the present invention unlocks the locking assembly 4 through the unlocking assembly, thereby releasing the locking state between the operating assembly 2 and the actuator 3. The operating assembly 2 is restricted by the shell 1 and cannot move in the direction (clockwise) in which the energy storage element 21 applies a torsional force to it, so that the actuator 3 is no longer restricted by the operating assembly 2 and rotates in another direction (counterclockwise) under the drive of the energy storage element 21, executing the opening action of the electrical control system state switching unit to achieve free tripping.

[0094] Changing the relative position between the operating component 2 and the actuator 3 may be changing the positions of the two along a straight line, or changing the positions of the two relative to each other, or changing the positions of the two along other paths.

[0095] The change here may be to adjust only the operating component 2, or only the actuator 3, or both.

[0096] The force applied by the energy storage element 21 to the operating assembly 2 may be a linear force, a rotational torsional force (ie, torsional torque), or a force in other directions or forms.

[0097] The embodiment of the present invention is to rotate the operating assembly 2 along a first direction (counterclockwise) to store energy in the energy storage element 21, and then rotate the operating assembly 2 along a second direction (clockwise) to close the circuit breaker.

[0098] In another embodiment, the operating assembly 2 can be rotated in the second direction (clockwise) to store energy in the energy storage element 21, and then the operating assembly 2 can be rotated in the first direction (counterclockwise) to close the circuit breaker. This also applies to linear motion or position changes in other forms of paths. That is, the relative position changes in one direction to store energy in the energy storage element 21, and then changes in the other direction to close the circuit breaker.

[0099] In an exemplary embodiment, as shown in Figures 1 to 3, the operating component 2 is rotated along a first direction (counterclockwise) to change the relative position between the operating component 2 and the actuator 3, so that the energy storage element 21 stores energy. After the operating component 2 is rotated to a predetermined position relative to the actuator 3, the operating component 2 can be connected to the actuator 3 through the locking component 4 and is in a locked state. Then, the operating component 2 is rotated along a second direction (clockwise) and drives the actuator 3 to rotate along the second direction (clockwise). The operating component 2 drives the actuator 3 to reach the restricted position of the operating component 2 restricted by the shell 1, thereby causing the actuator 3 to drive the position state of the electrical control system state switching unit to change.

[0100] In an exemplary embodiment, the operating component 2 and the actuator 3 are locked by the locking component 4 so that they can be combined into a whole and can move together. At the same time, the energy storage element 21 connected between the operating component 2 and the actuator 3 stores energy, which can force the operating component 2 and the actuator 3 to have a tendency to move away from each other relative to each other, or can force the operating component 2 and the actuator 3 to have a tendency to move closer to each other relative to each other.

[0101] The moving away or approaching here can be moving away or approaching in a linear direction, or can be moving away or approaching in a circumferential direction between the contact position of the energy storage element 21 and the operating component 2 (i.e., the energy storage element stop plate 35 of the actuator 3 contacted by the first torsion arm 211 of the energy storage element 21 introduced later) and the contact position of the energy storage element 21 and the actuator 3 (i.e., the drive plate 235 of the drive disk 23 of the operating component 2 contacted by the second torsion arm 212 of the energy storage element 21 introduced later) during the relative rotation process, or can be moving away or approaching in other forms of paths.

[0102] In an exemplary embodiment, as shown in FIG. 1 , the housing 1 includes a base 11 and a top cover 12 , and the base 11 and the top cover 12 form a receiving cavity.

[0103] In an exemplary embodiment, as shown in Figure 1, the housing 1 also includes a buffer 13 arranged on the base 11. When the energy storage element 21 releases energy and drives the actuator 3 to rotate along the first direction (counterclockwise), the buffer 13 can buffer and stop the actuator 3 to limit the rotation of the actuator 3 along the first direction (counterclockwise) and make the actuator 3 stay in the open position.

[0104] In the exemplary embodiment, as shown in Figures 3 and 32, the base 11 is provided with a first stopper 14 and a second stopper 15. The first stopper 14 can stop a locking rod fixing bent plate 231 of the drive disk 23, described later, to limit rotation of the drive disk 23 in the second direction (clockwise). The second stopper 15 can stop a driving plate 235 of the drive disk 23, described later, to limit rotation of the drive disk 23 in the second direction (clockwise). The dual stopper structure of the first stopper 14 and the second stopper 15 ensures stable positioning.

[0105] In FIG3 , two stoppers are provided. The number of the stoppers can be adjusted according to actual conditions, for example, it can be set to one, three or even more.

[0106] 25A and 25B , the actuator 3 includes a plate-shaped actuator body 38 having an actuator center hole 33 through which a drive shaft 22, described later, passes. The actuator body 38 is rotatably mounted within the base 11 .

[0107] The outer edge of the actuator body 38 has three upwardly extending energy storage element limiting plates, namely energy storage element limiting plate 341, energy storage element limiting plate 342, and energy storage element limiting plate 343. One of the three energy storage element limiting plates, energy storage element limiting plate 343, is located on a first side of the energy storage element limiting plates 341 and 342.

[0108] The energy storage element limiting plates 341 , 342 , and 343 are used to limit the position of the energy storage element 21 to be described later, so as to prevent the energy storage element 21 from being significantly offset during the energy storage process.

[0109] The outer edge of the actuator body 38 also has an upwardly extending push plate 32, a locking boss 31 and an energy storage element stop plate 35 in sequence, wherein the push plate 32, the locking boss 31 and the energy storage element stop plate 35 are located on the second side of the energy storage element limit plates 341 and 342.

[0110] The locking boss 31 can be locked in cooperation with the locking groove 412 of the locking rod 41 to be described later.

[0111] The push plate 32 can contact the stop plate 413 of the lock rod 41 in the lock assembly 4 introduced later, and can force the lock rod 41 to rotate around the lock rod fixing shaft 45 along the first direction (counterclockwise direction) after contact.

[0112] The energy storage element stop plate 35 cooperates with the buffer 13 to keep the actuator 3 stationary relative to the housing 1. The energy storage element first torsion arm 211 of the energy storage element 21, described later, abuts against the energy storage element stop plate 35, applying a torsional torque to the energy storage element stop plate 35 of the actuator 3 in a first direction (counterclockwise), thereby driving the actuator 3 to rotate in the first direction (counterclockwise).

[0113] The outer edge of the actuator body 38 further has a connection positioning plate 36 extending downward. The connection positioning plate 36 is located between the energy storage element limiting plate 343 and the energy storage element limiting plate 341 .

[0114] The connection positioning plate 36 extends downward from the base 11 and is connected to the electrical control system state switching unit.

[0115] The actuator body 38 further has a deflection torsion spring limiting hole 37 , into which the deflection torsion spring first torque arm 251 of the deflection torsion spring 25 to be described later is inserted.

[0116] In an exemplary embodiment, as shown in FIG. 1 , FIG. 35 and FIG. 36 , the unlocking assembly 5 includes an electromagnetic driving element 51 , an unlocking lever 52 , an unlocking lever return spring 53 and an unlocking lever fixing shaft 54 ​​.

[0117] The electromagnetic drive element 51 is mounted within the base 11 and is electrically connected to an external circuit and is capable of receiving a trigger signal from the external circuit. Upon receiving the trigger signal, the electromagnetic drive element 51 drives the unlocking lever 52 to rotate about the locking lever fixed axis 45 in a first direction (counterclockwise).

[0118] As shown in FIG30 , the unlocking lever 52 includes an unlocking lever body 525 having an unlocking lever center hole 521 through which the unlocking lever fixed shaft 54 ​​passes. The unlocking lever 52 is rotatably mounted within the base 11 via the unlocking lever fixed shaft 54 ​​(i.e., the center of rotation of the unlocking lever 52 is the unlocking lever fixed shaft 54).

[0119] The first end of the unlocking lever body 525 has a first extension plate 526 extending downward, and an unlocking lever push rod 522 extending from the lower end of the first extension plate 526 away from the unlocking lever body 525. The unlocking lever push rod 522 is close to or in contact with the electromagnetic drive element 51 and can be pushed by the electromagnetic drive element 51. Similarly, the unlocking lever push rod 522 can also push the electromagnetic drive element 51 to reset the electromagnetic drive element 51 after unlocking is triggered.

[0120] The second end of the unlocking lever body 525 has a second extension plate 527 extending downward, and an unlocking lever pressing rod 523 extending from the lower end of the second extension plate 527 in a direction away from the unlocking lever body 525. The unlocking lever pressing rod 523 can approach or contact the tripping arm 434 of the tripping lever 43, and can drive the tripping lever 43 to rotate about the tripping lever fixed axis 46 in the second direction (clockwise) by pressing the tripping arm 434, thereby unlocking the lock assembly 4.

[0121] When the unlocking lever 52 rotates along the first direction (counterclockwise), the unlocking lever pressing rod 523 can push the tripping arm 434 of the tripping lever 43 to be described later.

[0122] An unlocking lever stop plate 528 is provided near the first end of the unlocking lever body 525 , and one end of the unlocking lever return spring 53 is abutted against the unlocking lever stop plate.

[0123] The unlocking lever body 525 has an unlocking lever reset boss 524 near the second end. When the drive disk 23 described later rotates in the first direction (counterclockwise), it can push the unlocking lever reset boss 524, so that the unlocking lever 52 rotates around the unlocking lever fixed axis 54 in the second direction (clockwise), so that the electromagnetic drive element 51 after the unlocking is triggered is reset. Alternatively, when the drive disk 23 described later rotates in the second direction (clockwise), it can also push the unlocking lever reset boss 524, so that the unlocking lever 52 rotates around the unlocking lever fixed axis 54 in the second direction (clockwise), so that the electromagnetic drive element 51 after the unlocking is triggered is reset.

[0124] The unlocking lever return spring 53 is used to provide elastic support force to the unlocking lever 52, so that the unlocking lever push rod 522 of the unlocking lever 52 remains close to or in contact with the electromagnetic drive element 51, and prevents the unlocking lever 52 from rotating.

[0125] In an exemplary embodiment, as shown in FIG. 1 , the operating assembly 2 includes an energy storage element 21 , a drive shaft 22 , a drive disc 23 , a sleeve 24 , and a deflection torsion spring 25 .

[0126] The energy storage element 21 is a torsion spring accumulator or a spring coil accumulator.

[0127] The energy storage element 21 is sleeved on the sleeve 24 and has a first energy storage element torsion arm 211 and a second energy storage element torsion arm 212 extending radially outward (see FIG. 21 for details).

[0128] The first torsion arm 211 of the energy storage element is stopped on the energy storage element stop plate 35 of the actuator 3. The first torsion arm 211 of the energy storage element can apply a torsional torque to the energy storage element stop plate 35 of the actuator 3 along the first direction (counterclockwise direction) so that the actuator 3 rotates around the drive shaft 22 along the first direction (counterclockwise direction).

[0129] The second torsion arm 212 of the energy storage element is abutted against the driving plate 235 of the driving disk 23 to be introduced later. The second torsion arm 212 of the energy storage element can be twisted under the drive of the driving disk 23 to enable the energy storage element 21 to store energy. At the same time, the second torsion arm 212 of the energy storage element can apply a torsional torque in the second direction (clockwise direction) to the driving plate 235 of the driving disk 23.

[0130] The drive shaft 22 passes through the top cover 12 , the drive disc 23 , the sleeve 24 , the deflection torsion spring 25 , the actuator center hole 33 of the actuator body 38 of the actuator 3 , and the base 11 in sequence from top to bottom.

[0131] A handle 16 is installed on the top of the driving shaft 22 , and the user drives the driving shaft 22 to rotate around its own axis through the handle 16 .

[0132] As shown in FIG. 1 , the drive shaft 22 includes a rotating shaft 221 , a pin 222 , a sealing ring 223 and a retaining ring 224 .

[0133] As shown in Figure 2, shaft 221 forms the main structure of drive shaft 22, passing, from top to bottom, through top cover 12, drive plate 23, sleeve 24, deflection spring 25, actuator center hole 33 of actuator body 38 of actuator 3, and base 11. Shaft 221 is connected to handle 16 via pin 222.

[0134] As shown in Figure 2, a sealing ring 223 is provided on the rotating shaft 221 and engages with the rotating shaft mounting hole provided on the top cover 12 to achieve a sealing effect between the rotating shaft 221 and the top cover 12. A retaining ring 224 is provided between the rotating shaft 221 and the base 11 to limit the actuator 3 in the axial direction to prevent it from moving downward.

[0135] As shown in Figures 22A and 22B, the drive disk 23 includes a plate-shaped drive disk body 236. The sleeve 24 supports the drive disk 23. The outer edge of the drive disk body 236 has a downwardly extending locking rod fixing bent plate 231 and a trip rod fixing bent plate 232. The locking rod fixing bent plate 231 is used to mount the locking rod 41, which will be described later, while the trip rod fixing bent plate 232 is used to mount the trip rod 43, which will be described later.

[0136] The driving disc body 236 also has three limiting slots 233, a driving disc center hole 234 and a driving plate 235 extending downward from one of the limiting slots 233. The driving plate 235 may not extend downward from the limiting slot 233, but may extend downward from other positions.

[0137] The limiting chute 233 has a predetermined length in the circumferential direction. The limiting chute 233 has a first limiting surface 233A at a first end in the circumferential direction and a second limiting surface 233B at a second end in the circumferential direction. The limiting chute 233 extends from the first limiting surface 233A to the second limiting surface 233B along a first direction (counterclockwise) (see FIG. 7A for details). The number of limiting chute 233 can be adjusted according to actual conditions, for example, it can be set to any number between 1 and 6.

[0138] The sleeve drive boss 242 of the sleeve 24 introduced later is inserted into the corresponding limiting groove 233. The sleeve drive boss 242 can slide along the limiting groove 233 so that the sleeve 24 can rotate around the drive shaft 22 relative to the drive disk 23 by a predetermined angle, thereby realizing the handle deflection indication.

[0139] The central hole 234 of the driving disk is used for the rotating shaft 221 of the driving shaft 22 to pass through.

[0140] When the driving plate 235 rotates along the first direction (counterclockwise), the driving plate 235 can push the second torsion arm 212 of the energy storage element to twist, so that the energy storage element 21 stores energy.

[0141] The driving plate body 236 further has a clearance slot 237. One of the second torsion arms 422 of the locking lever torsion spring, which will be described later, can pass through the clearance slot 237 of the driving plate 23, so that one of the second torsion arms 422 of the locking lever torsion spring 42 slides along the clearance slot 237, thereby preventing the driving plate 23 from hindering the torsion of the second torsion arm 422 of the locking lever torsion spring.

[0142] The drive disk body 236 also has a drive disk boss 238. When the drive disk 23 rotates in the first direction (counterclockwise), the drive disk boss 238 can push the unlocking rod reset boss 524, so that the unlocking rod 52 rotates around the unlocking rod fixed axis 54 in the second direction (clockwise).

[0143] In an exemplary embodiment, as shown in FIG. 2 , the sleeve 24 is sleeved on the rotating shaft 221 of the driving shaft 22 , and the sleeve 24 rotates synchronously with the driving shaft 22 .

[0144] As shown in Figure 23A, the sleeve 24 has a sleeve center hole 241 that passes through in the vertical direction. The top of the sleeve 24 has three sleeve drive bosses 242. Each sleeve drive boss 242 is inserted into the corresponding limiting groove 233 of the drive disk 23. The sleeve drive boss 242 can slide along the limiting groove 233 so that the sleeve 24 can rotate a predetermined angle relative to the drive disk 23 around the axis where the drive shaft 22 is located, thereby realizing the handle deflection indication.

[0145] The number of the limiting sliding slots 233 can be adjusted according to actual conditions, for example, it can be set to any number between 1 and 6.

[0146] As shown in FIG. 23B , the bottom of the sleeve 24 has a recessed hole 243 , a relief groove 244 and a limiting groove 245 .

[0147] The recessed hole 243 is used to accommodate the deflection torsion spring 25 .

[0148] The clearance groove 244 is used to accommodate a first torsion arm 251 of the deflection torsion spring 25 (see FIG19B for details), and the limiting groove 245 is used to accommodate a second torsion arm 252 of the deflection torsion spring 25 (see FIG19B for details). The clearance groove 244 has a predetermined length in the circumferential direction. The clearance groove 244 has a first clearance end surface 244A at a first end in the circumferential direction and a second clearance end surface 244B at a second end in the circumferential direction. The clearance groove 244 extends from the first clearance end surface 244A to the second clearance end surface 244B along the second direction (clockwise direction) (see FIG23A and FIG23B for details). The first torsion arm 251 of the deflection torsion spring 25 can slide along the clearance groove 244.

[0149] As shown in FIG. 2 , the deflection torsion spring 25 is installed in the recessed hole 243 of the sleeve 24 . As shown in FIG. 24 , the deflection torsion spring 25 has a first deflection torsion spring torsion arm 251 and a second deflection torsion spring torsion arm 252 .

[0150] The first torsion arm 251 of the deflection torsion spring passes through the clearance groove 244 of the sleeve 24 and is inserted into the deflection torsion spring limiting hole 37 of the actuator body 38 of the actuator 3 (see FIG. 19A for details).

[0151] The setting angle of the give way groove 244 is greater than the movable range of the first torsion arm 251 of the deflection torsion spring, and there is a gap margin, that is, the first torsion arm 251 of the deflection torsion spring will not contact the first give way end face 244A and the second give way end face 244B, so that the first torsion arm 251 of the deflection torsion spring has movable space.

[0152] The second torsion arm 252 of the deflection torsion spring is inserted into the limiting groove 245 of the sleeve 24 and is capable of applying a torsional moment to the sleeve 24 .

[0153] As shown in FIG2 , the base 11 supports the actuator 3 , the actuator 3 supports the sleeve 24 , and the sleeve 24 supports the drive disc 23 . The sleeve 24 can transmit the torsional torque of the drive shaft 22 to the drive disc 23 .

[0154] As shown in FIG31 , a step 225 is provided on the rotating shaft 221 of the driving shaft 22 , and the driving disc 23 is provided below the step 225 . The step 225 can limit the upward movement of the driving disc 23 in the axial direction.

[0155] The step 225 and the retaining ring 224 of the drive shaft 22 are combined to limit the axial movement of the actuator 3, the deflection torsion spring 25, the sleeve 24, and the drive disc 23.

[0156] In an exemplary embodiment, the locking assembly 4 includes a locking portion and a release portion. By changing the position state of the locking portion, the connection between the operating assembly 2 and the actuator 3 is achieved and locked, so that the operating assembly 2 can move in the same direction as the actuator 3, thereby driving the position state of the electrical control system state switching unit to change.

[0157] Alternatively, the unlocking component 2 changes the position state of the tripping portion to release the locking state between the operating component 2 and the actuator 3, thereby allowing the energy storage element 21 to release energy and drive the actuator 3 to move.

[0158] In the exemplary embodiment, as shown in Figures 1, 37, and 38, the lock assembly 4 includes a lock rod 41, a lock rod torsion spring 42, a trip rod 43, a trip rod torsion spring 44, a lock rod fixing shaft 45, and a trip rod fixing shaft 46. The lock rod 41 and the lock rod torsion spring 42 constitute a lock portion, and the trip rod 43 and the trip rod torsion spring 44 constitute a trip portion.

[0159] As shown in FIG4 , the striker lever 41 is mounted to the striker lever fixed bent plate 231 via a striker lever fixed shaft 45 and is rotatable about the striker lever fixed shaft 45. As shown in FIG26A , the striker lever 41 includes a horizontal striker lever upper plate 416, a striker lever lower plate 417, and a vertical striker lever connecting plate 418. The striker lever upper plate 416 is connected to the striker lever lower plate 417 via the striker lever connecting plate 418.

[0160] The locking rod upper plate 416 and the locking rod lower plate 417 each have a locking rod limiting hole 411 , and the locking rod limiting hole 411 allows the locking rod fixing shaft 45 to pass through.

[0161] The lock rod lower plate 417 has a stop plate 413, which can contact the push plate 32 of the actuator 3 and force the lock rod 41 to rotate around the lock rod fixed axis 45 along the first direction (counterclockwise direction) after contact.

[0162] The end surface of the locking rod connecting plate 418 facing the locking rod limiting hole 411 has a locking groove 412, and the end surface of the locking rod connecting plate 418 away from the locking rod limiting hole 411 is a locking rod abutting surface 414. The locking rod connecting plate 418 also has a locking rod stopping surface 415 facing away from the stopping plate 413 (see Figure 26B for details).

[0163] The locking groove 412 can cooperate with the locking boss 31 of the actuator 3 to lock.

[0164] The locking rod abutting surface 414 of the locking rod 41 can form an abutting state with the tripping rod abutting surface 433 of the tripping rod lower plate 436 of the tripping rod 43 to be described later, thereby achieving the first locking state.

[0165] The locking rod stop surface 415 of the locking rod 41 can cooperate with the tripping rod stop surface 432 of the tripping rod 43 to be described later to form a resisting state.

[0166] The lock bar torsion spring 42 is mounted to the lock bar fixed shaft 45 . As shown in FIG. 27 , the lock bar torsion spring 42 has a lock bar torsion spring first torsion arm 421 and two lock bar torsion spring second torsion arms 422 .

[0167] The first torsion arm 421 of the locking rod torsion spring is abutted against the locking rod fixed bent plate 231 .

[0168] One of the two second torsion arms 422 of the torsion spring of the locking rod abuts against the upper plate 416 of the locking rod and is inserted into the clearance groove 237 of the driving disk 23, thereby providing a torsional torque to the upper plate 416 of the locking rod. The other of the two second torsion arms 422 of the torsion spring of the locking rod abuts against the lower plate 417 of the locking rod and is thereby providing a torsional torque to the lower plate 417. During the rotation of the locking rod 41 about the locking rod fixed axis 45, one of the two second torsion arms 422 of the torsion spring of the locking rod 42 can slide along the clearance groove 237 of the driving disk 23, thereby preventing the driving disk 23 from obstructing the torsion of one of the two second torsion arms 422 of the torsion spring of the locking rod 42.

[0169] The lock lever torsion spring 42 can apply a torsional moment to the lock lever 41 to cause the lock lever 41 to rotate in the second direction (clockwise direction), or to cause the lock lever 41 to have a tendency to rotate in the second direction (clockwise direction).

[0170] The trip rod 43 is mounted to the trip rod fixed bent plate 232 (see FIG33 for details) via the trip rod fixed shaft 46 and is rotatable about the trip rod fixed shaft 46. As shown in FIG28 , the trip rod 43 includes a horizontal trip rod upper plate 435, a trip rod lower plate 436, and a vertical trip rod connecting plate 437. The trip rod upper plate 435 is connected to the trip rod lower plate 436 via the trip rod connecting plate 437. The height of the trip rod upper plate 435 of the trip rod 43 is approximately flush with the height of the lock rod upper plate 416 of the lock rod 41, and the height of the trip rod lower plate 436 of the trip rod 43 is between the height of the lock rod upper plate 416 of the lock rod 41 and the height of the lock rod lower plate 417.

[0171] The tripping rod upper plate 435 and the tripping rod lower plate 436 each have a tripping rod limiting hole 431. The tripping rod limiting hole 431 is for the tripping rod fixing shaft 46 to pass through.

[0172] The trip rod lower plate 436 has a trip rod stopping surface 432 and a trip rod abutting surface 433 .

[0173] The trip rod stop surface 432 is used to cooperate with the lock rod stop surface 415 on the lock rod 41 to form a resisting state. In this resisting state, the operating component 2 completes the locking of the actuator 3 into an interlocking structure through the lock component 4, that is, the second locking state.

[0174] The tripping rod abutting surface 433 of the tripping rod lower plate 436 of the tripping rod 43 and the locking rod abutting surface 414 of the locking rod 41 form an abutting state, thereby reaching the second locking state.

[0175] The trip lever lower plate 436 also has a trip arm 434. When the unlocking lever 52 rotates in the first direction (counterclockwise), the unlocking lever pressing rod 523 of the unlocking lever 52 can push the trip arm 434 of the trip lever 43, so that the trip lever 43 rotates in the second direction (clockwise) around the trip lever fixed shaft 46.

[0176] When the trip rod 43 rotates around the trip rod fixing shaft 46 in the second direction (clockwise), the trip rod 43 can twist the trip rod torsion spring 44 , so that the trip rod torsion spring 44 stores energy.

[0177] When the tripping rod 43 rotates around the tripping rod fixing shaft 46 in the second direction (clockwise direction), the tripping rod 43 can release the abutment against the locking rod 41 .

[0178] The trip lever torsion spring 44 is mounted to the trip lever fixed shaft 46 . As shown in FIG. 29 , the trip lever torsion spring 44 includes a first torsion arm 441 and a second torsion arm 442 .

[0179] The first torsion arm 441 of the trip rod torsion spring abuts against the trip rod fixed bent plate 232, and the second torsion arm 442 of the trip rod torsion spring abuts against the trip rod connecting plate 437 of the trip rod 43, thereby applying a torsional torque to the trip rod 43. In other words, the trip rod torsion spring 44 can apply a torsional torque to the trip rod 43, thereby causing the trip rod 43 to rotate in the first direction (counterclockwise) or causing the trip rod 43 to have a tendency to rotate in the first direction (counterclockwise).

[0180] There are two locking states between the actuator 3 and the lock assembly 4:

[0181] First lock state:

[0182] The trip rod abutting surface 433 of the trip rod lower plate 436 of the trip rod 43 forms an abutting state with the locking rod abutting surface 414 of the locking rod 41 (see Figure 5 for coordination), that is, a locking state between the locking rod 41 and the trip rod 43. At this time, the locking boss 31 of the actuator 3 is not locked with the locking groove 412 of the locking rod 41.

[0183] Second lock state:

[0184] The trip rod stop surface 432 of the trip rod lower plate 436 of the trip rod 43 forms abutting state with the lock rod stop surface 415 of the lock rod 41 (see Figure 6 and Figure 20 for cooperation), and the lock boss 31 of the actuator 3 is located in the lock groove 412 of the lock rod 41, and the lock boss 31 of the actuator 3 cooperates with the lock groove 412 of the lock rod 41 to be locked (see Figure 12 for cooperation), that is, the locking state between the lock rod 41, the trip rod 43 and the actuator 3, so that the actuator 3 can be connected with the operating component 2 through the lock component 4 and be in a locked state.

[0185] The deflection torsion spring 25 has two energy storage states:

[0186] One is the reverse torsion (expanded direction in the torsion spring) energy storage state, in which the first torsion arm 251 of the deflection torsion spring and the second torsion arm 252 of the deflection torsion spring have a tendency to contract inward, that is, the first torsion arm 251 of the deflection torsion spring applies a torsion torque along the second direction (clockwise) to the actuator 3, and the second torsion arm 252 of the deflection torsion spring 25 applies a torsion torque along the first direction (counterclockwise) to the sleeve 24.

[0187] The other is the forward torsional (shrinking direction in the torsion spring) energy storage state, in which the first torsion arm 251 of the deflection torsion spring and the second torsion arm 252 of the deflection torsion spring have a tendency to expand outward, that is, the first torsion arm 251 of the deflection torsion spring applies a torsional torque along the first direction (counterclockwise) to the actuator 3, and the second torsion arm 252 of the deflection torsion spring 25 applies a torsional torque along the second direction (clockwise) to the sleeve 24.

[0188] The operation of the energy storage mechanism for state switching operation of an electrical control system according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0189] Before re-energizing, the energy storage mechanism for operating the electrical control system state switching unit is in the state shown in FIG7A : the tripping rod abutting surface 433 of the tripping rod lower plate 436 of the tripping rod 43 forms an abutting state with the locking rod abutting surface 414 of the locking rod 41, and the locking boss 31 of the actuator 3 is not locked with the locking groove 412 of the locking rod 41, i.e., the first locked state. Furthermore, the sleeve driving boss 242 of the sleeve 24 contacts the first limiting surface 233A. The energy storage element stop plate 35 of the actuator 3 contacts the buffer member 13 on the base 11, and the actuator 3 is in the open position.

[0190] The deflection torsion spring 25 is in a reverse torsion (expanded direction in the torsion spring) energy storage state (the stored energy at this time is the energy stored after the free tripping process is completed), the first torsion arm 251 of the deflection torsion spring is in a position close to the first yielding end face 244A (see Figure 7B for details), and the first torsion arm 251 of the deflection torsion spring applies a torsional torque along the second direction (clockwise) to the actuator 3, and the second torsion arm 252 of the deflection torsion spring 25 applies a torsional torque along the first direction (counterclockwise) to the sleeve 24 to push the corresponding handle 16 to deflect a certain angle, that is, deflect to the tripping position.

[0191] The energy storage element 21 is in a pre-tightened state, and the first torsion arm 211 of the energy storage element 21 applies a torsion torque along the first direction (counterclockwise direction) to the energy storage element stop plate 35 of the actuator 3, and the second torsion arm 212 of the energy storage element 21 applies a torsion torque along the second direction (clockwise direction) to the drive plate 235 of the drive disk 23.

[0192] In the embodiment of FIG. 7A , the indicated direction of the pin 222 is the direction of the handle 16 .

[0193] Re-deduction energy storage process:

[0194] Manually rotating the handle 16 in the first direction (counterclockwise) causes the drive shaft 22 to rotate in the first direction (counterclockwise), thereby driving the sleeve 24 to rotate in the first direction (counterclockwise), thereby driving the drive disk 23 to rotate in the first direction (counterclockwise). The drive disk 23 drives the lock assembly 4 (in the first locked state) to rotate around the drive shaft 22 in the first direction (counterclockwise) (see Figures 7A and 8A for details).

[0195] During the process of the driving disk 23 rotating along the first direction (counterclockwise direction), the driving disk boss 238 of the driving disk 23 can push the unlocking rod reset boss 524 of the unlocking rod 52 (see Figure 8A for details) to push the unlocking rod 52 to rotate along the first direction (counterclockwise direction) around the unlocking rod fixed axis 54, thereby causing the unlocking rod push rod 522 of the unlocking rod 52 to push the electromagnetic driving element 51 of the unlocking assembly 5, thereby resetting the electromagnetic driving element 51 of the unlocking assembly 5 (see Figure 7A, Figure 8A and Figure 9A for details).

[0196] As the drive disc 23 rotates in the first direction (counterclockwise), the drive plate 235 of the drive disc 23 twists the energy storage element second torsion arm 212 of the energy storage element 21 (see FIG18 ), causing the energy storage element 21 to store energy. The energy storage element first torsion arm 211 of the energy storage element 21 applies a torsional torque in the first direction (counterclockwise) to the energy storage element stop plate 35 of the actuator 3. However, the energy storage element stop plate 35 of the actuator 3 is restrained by the buffer 13. Therefore, the deflection spring first torsion arm 251 of the deflection spring 25 and the actuator 3 are both stationary relative to the base 11 of the housing 1.

[0197] Continue to rotate the handle 16 in the first direction (counterclockwise), the drive disk 23 and the locking assembly 4 continue to rotate in the first direction (counterclockwise) around the drive shaft 22, and the drive disk 23 drives the stop plate 413 of the locking rod 41 in the locking assembly 4 to contact the push plate 32 set on the actuator 3 (see Figure 10 for coordination).

[0198] Since the actuator 3 is in a stationary state relative to the housing 1 at this time, when the lock assembly 4 continues to rotate around the drive shaft 22 in the first direction (counterclockwise), the push plate 32 of the actuator 3 will contact the stop plate 413 of the lock rod 3 and push the stop plate 413 to move, thereby prompting the lock rod 41 in the lock assembly 4 to rotate around the lock rod fixed axis 45 in the first direction (counterclockwise).

[0199] During the process of the locking rod 41 rotating around the locking rod fixed axis 45 along the first direction (counterclockwise direction), the locking rod connecting plate 418 of the locking rod 41 pushes the locking rod torsion spring first torsion arm 421 of the locking rod torsion spring 42 to twist, so that the locking rod torsion spring 42 stores energy. At the same time, the locking rod abutting surface 414 of the locking rod 41 no longer abuts against the tripping rod abutting surface 433 of the tripping rod lower plate 436 of the tripping rod 43 (see Figure 10 for coordination), that is, the first locking state is released.

[0200] As shown in FIG10 and FIG11 , after the locking rod abutting surface 414 of the locking rod 41 is disengaged from the tripping rod abutting surface 433 of the tripping rod 43 , the locking rod 41 no longer restricts the tripping rod 43 from rotating in the first direction (counterclockwise).

[0201] Under the action of the torsional torque provided by the trip rod torsion spring 44, the trip rod 43 rotates around the trip rod fixed axis 46 in the first direction (counterclockwise) until the stop surface 438 of the trip arm 434 of the trip rod 43 contacts the trip rod fixed bent plate 232 of the operating assembly 2 and stops rotating (see Figure 11 for details).

[0202] During the process of the locking rod 41 rotating along the first direction (counterclockwise) around the locking rod fixed axis 45, the tripping rod 43 rotates along the first direction (counterclockwise) until the locking rod stop surface 415 of the locking rod 41 is close to the tripping rod stop surface 432 of the tripping rod 43. At this time, the locking boss 31 of the actuator 3 passes over and enters the locking groove 412 of the locking rod 41, but the locking boss 31 does not contact the locking groove 412 (see Figure 11 for coordination).

[0203] When the stopper plate 413 of the lock rod 41 contacts the lock rod fixed bent plate 231 of the drive disk 23, the lock rod 41 no longer rotates in the first direction (counterclockwise) about the lock rod fixed axis 45 (see Figure 11 for details). At this time, the handle 16 is twisted in the first direction (counterclockwise) to the maximum twisting position during the re-locking energy storage process. In Figure 11, the contact point between the stopper plate 413 of the lock rod 41 and the lock rod fixed bent plate 231 of the drive disk 23 is exactly blocked by the lock rod torsion spring 42.

[0204] The handle 16 is released to release the driving force of the driving shaft 22 , thereby releasing the driving force of the driving disk 23 .

[0205] Under the action of the torsional torque provided by the energy storage element 21, the energy storage element first torsion arm 211 of the energy storage element 21 can apply torsional torque to the drive plate 235 of the drive disk 23 in the second direction (clockwise), causing the drive disk 23 to rotate in the second direction (clockwise), thereby driving the lock rod 41 to rotate in the second direction (clockwise) around the drive shaft 22. When the lock boss 31 contacts the lock groove 412 of the lock rod 41, and the trip rod stop surface 432 forms an abutment with the lock rod stop surface 415 of the lock rod 41 (see Figure 12 for details), i.e., in the second locked state, the drive disk 23 stops rotating.

[0206] During the process of the locking rod 41 rotating around the drive shaft 22 along the second direction (clockwise direction), the push plate 32 of the actuator 3 moves away from the stop plate 413 set on the locking rod 3, releasing the abutment between the push plate 32 and the stop plate 413, and under the combined action of the torsional torque applied by the locking rod torsion spring 42 and the locking boss 31 of the actuator 3, the locking rod 41 rotates around the locking rod fixed axis 45 along the second direction (clockwise direction) until the locking groove 412 of the locking rod 41 is locked with the locking boss 31 of the actuator 3 (see Figures 11 and 12 for coordination). At this time, the operating component 2 is locked with the actuator 3 through the locking component 4 into an interlocking structure, that is, the second locking state.

[0207] During the re-buckle energy storage process, the actuator 3 is restricted by the buffer member 13 and is in a relatively static state relative to the housing 1 , and the actuator 3 does not perform a switching action.

[0208] After the handle 16 is released, its deflection torsion spring 25 is in a forward torsion state. Under the torsional torque provided by the deflection torsion spring 25, the sleeve 24 rotates in the second direction (clockwise), thereby driving the handle 16 to rotate in the second direction (clockwise) back to the opening indication position.

[0209] During the re-buckle energy storage process, the specific changes of the deflection torsion spring 25 are as follows:

[0210] During the re-buckle energy storage process, the deflection torsion spring 25 is connected to the actuator 3 by the first torsion arm 251, which is a fixed torsion arm. When the handle 16 is rotated along the first direction (counterclockwise) by the first preset angle, the storage torque of the deflection torsion spring 25 is released (in a certain state in Figure 8B to Figure 9B, since the re-buckle energy storage process involves over-twisting by the second preset angle, the deflection torsion spring should be in the middle of the give way groove 244, deviating to a position about the second preset angle of the first limit surface 233A, and the energy release of the deflection torsion spring is completed).

[0211] In the illustrated embodiment, the first preset angle is 40 degrees, but its value can be adjusted according to circumstances, for example, it can be set to any number between 30 degrees and 50 degrees.

[0212] In the illustrated embodiment, the second preset angle is 8 degrees, but its value can be adjusted according to circumstances, for example, it can be set to any number between 3 degrees and 15 degrees.

[0213] Continue to rotate the handle 16 along the first direction (counterclockwise) to rotate the deflection torsion spring 25 clockwise (the direction of the torsion spring after shrinkage), that is, drive the deflection torsion spring second torsion arm 252 to twist counterclockwise, so that the deflection torsion spring 25 stores energy again (clockwise energy storage). At this time, the deflection torsion spring second torsion arm 252 of the deflection torsion spring 25 applies a torsional torque to the sleeve 24 along the second direction (clockwise), and the deflection torsion spring first torsion arm 251 of the deflection torsion spring 25 applies a torsional torque to the actuator 3 along the first direction (counterclockwise).

[0214] After the energy is stored again, the second locking state is completed.

[0215] Release the handle 16, and under the action of the deflection torsion spring 25, the sleeve 24 drives the sleeve 24 to rotate along the second direction (clockwise) until the sleeve driving boss 242 of the sleeve 24 contacts the second limiting surface 233B of the limiting slide groove 233 and stops (see Figure 12 for details). At this time, the handle 16 is deflected from the over-tightening angle to the open position, and the pin 222 corresponding to the handle 16 is also deflected from the over-tightening angle to the open position (see Figures 11 to 12 for details).

[0216] Manual closing process:

[0217] As shown in Figure 13, after the aforementioned re-buckle energy storage is completed, the handle 16 is rotated in the second direction (clockwise). The handle 16 drives the operating assembly 2 to rotate in the second direction (clockwise), which in turn drives the actuator 3, which is locked with it, to rotate in the second direction (clockwise). The connection positioning plate 36 of the actuator 3 can perform the closing operation of the electrical control system state switching unit. At this time, the locking rod fixed bent plate 231 of the drive disk 23 is restrained by the first stop portion 14 of the base 11, and the drive plate 235 of the drive disk 23 is restrained by the second stop portion 15 of the base 11, so that the drive disk 23 cannot further rotate in the second direction (clockwise).

[0218] Manual opening process:

[0219] As shown in Figure 14, when the above-mentioned closing is completed, the handle 16 is rotated along the first direction (counterclockwise), and the handle 16 drives the operating component 2 to rotate along the first direction (counterclockwise), and can also drive the actuator 3 in a locked state therewith to rotate along the first direction (counterclockwise). The connection positioning plate 36 of the actuator 3 can execute the opening action of the electrical control system state switching unit.

[0220] During the process of manual closing and manual opening, the interior of the lock assembly 4 is in the second locking state, and the energy storage element 21 is in the energy storage state.

[0221] The energy storage torque of the energy storage element 21 is greater than the energy storage torsional moment of the internal energy storage element of the operating mechanism of the state switching unit of the electrical control system.

[0222] Free tripping process:

[0223] As shown in Figures 15 and 34, after the above-mentioned closing action is completed, in some special cases, the electromagnetic drive element 51 of the unlocking assembly 5 is triggered after receiving the unlocking signal to push the unlocking rod push rod 522, so that the unlocking rod 52 rotates around the unlocking rod fixed axis 54 along the first direction (counterclockwise direction), and then the unlocking rod pressure rod 523 of the unlocking rod 52 pushes the tripping arm 434 of the tripping rod 43 to move, so that the tripping rod 43 rotates around the tripping rod fixed axis 46 along the second direction (clockwise direction).

[0224] As the trip lever 43 rotates in the second direction (clockwise) about the trip lever fixed axis 46, the trip lever connecting plate 437 of the trip lever 43 twists the second torsion arm 442 of the trip lever torsion spring 44, causing the trip lever torsion spring 44 to store energy. Simultaneously, the trip lever 43 rotates in the second direction (clockwise) about the trip lever fixed axis 46 until the locking lever stop surface 415 of the locking lever 41 no longer abuts the trip lever stop surface 432 of the trip lever 43, thereby releasing the second locking state (see FIG15 for details).

[0225] After the locking rod stop surface 415 of the locking rod 41 and the tripping rod stop surface 432 of the tripping rod 43 no longer abut against each other, the tripping rod 43 releases the abutment with the locking rod 41 and no longer restricts the locking rod 41 from rotating in the second direction (clockwise direction).

[0226] Under the action of the torsional torque provided by the lock rod torsion spring 421, the lock rod 41 rotates around the lock rod fixed axis 45 in the second direction (clockwise) until the lock rod stop surface 415 on the lock rod 41 contacts the trip rod fixed bent plate 232 and stops rotating, or contacts the trip arm 434 of the trip rod 43. At the same time, the lock rod abutting surface 414 of the lock rod 41 approaches or abuts the trip rod abutting surface 433 of the trip rod 43 (see Figure 16 for details). When the unlocking rod 52 is reset, the lock rod abutting surface 414 of the lock rod 41 and the trip rod abutting surface 433 of the trip rod 43 are in a complete abutment state; if the unlocking rod 52 continues to apply force to the trip rod 43, the lock rod abutting surface 414 of the lock rod 41 and the trip rod abutting surface 433 of the trip rod 43 can be in a close state or in abutment.

[0227] When the locking rod 41 rotates in the second direction (clockwise) around the locking rod fixed axis 45, the locking groove 412 of the locking rod 41 disengages from the locking boss 31 provided on the actuator 3, so that the locking rod 41 no longer restricts the rotation of the actuator 3 in the first direction (counterclockwise), that is, the locking rod 41 and the tripping rod 43 provided on the locking assembly 4 are in the first locking state.

[0228] The first torsion arm 211 of the energy storage element 21 applies a torsional torque to the energy storage element stop plate 35 of the actuator 3 (the torsional torque is much larger than the torsional torque of the deflection torsion spring 25, and larger than the energy storage torsional torque of the internal energy storage element of the operating mechanism of the electrical control system state switching unit), so that the actuator 3 rotates around the drive shaft 22 in the first direction (counterclockwise direction) (see Figure 17 for details), and then the automatic opening action of the electrical control system state switching unit can be executed to realize the free tripping process (i.e., automatic opening process).

[0229] When the actuator 3 rotates in the first direction (counterclockwise) to the opening position, it collides with the buffer 13 provided on the base 11 and stops (see FIG. 17 for details).

[0230] During the energy release process of the energy storage element 21, a torsional torque is applied to the driving disk 23. The torsional torque causes the driving disk 23 to tend to rotate along the second direction (clockwise direction). The locking rod fixed bent plate 231 of the driving disk 23 is restricted by the first stop portion 14 of the base 11, and the driving plate 235 of the driving disk 23 is restricted by the second stop portion 15 of the base 11. The driving disk 23 cannot rotate along the first direction (counterclockwise direction), and the driving disk 23 is static relative to the base 11.

[0231] After free tripping, the energy storage element 21 applies a torsional torque along the second direction (clockwise direction) to the drive disk 23 of the operating component 2, and the first stop portion 14 and the second stop portion 15 of the base 11 of the shell 1 can limit the clockwise rotation of the drive disk 23 of the operating component 2.

[0232] Handle deflection indication:

[0233] After the free tripping process, the handle 16 needs to be rotated back to the tripping position, that is, the handle deflection indication needs to be automatically achieved.

[0234] When the switch is in the closed state, the handle 16 points to the closed position.

[0235] When free tripping is performed, that is, when the handle 16 or the rotating shaft is stuck, free tripping can be achieved and automatic opening is completed; when the release handle 16 is stuck or the rotating shaft 221 connected to the release handle 16 is stuck, the handle 16 cannot point to the closing position, and the handle 16 needs to be driven to deflect a certain angle from the closing position to the opening position.

[0236] At this time, the deflection torsion spring 25 can drive the sleeve 24 to drive the drive shaft 22 and the handle 16 to rotate along the first direction (counterclockwise) to point to the tripping position.

[0237] Before free tripping, the deflection torsion spring is in an energy storage state (the stored energy at this time is the energy stored after the re-tripping process is completed).

[0238] In the first stage of the free tripping process, the torsional torque applied by the first torsion arm 251 of the deflection torsion spring to the actuator 3 is along the first direction (counterclockwise), that is, the actuator 3 is driven to rotate along the first direction (counterclockwise). When the stored energy of the deflection torsion spring 25 is released, the first stage of the free tripping process ends.

[0239] In the second stage of the free tripping process, under the action of the torsional torque provided by the energy storage element 21, the actuator 3 drives the first torsion spring torsion arm 251 to rotate along the first direction (counterclockwise), so that the deflection torsion spring 25 stores energy again (reverse torsion energy storage). After the deflection torsion spring 25 stores energy, the second torsion spring 252 of the deflection torsion spring 25 is connected to the sleeve 24, and the second torsion spring 252 applies a torsion torque along the first direction (counterclockwise) to the sleeve 24 to drive the sleeve 24 to rotate along the first direction (counterclockwise) within the range of motion of the limiting slide 233 of the drive disk 23 (i.e., from the position in contact with the second limiting surface 233B to the position in contact with the first limiting surface 233A), thereby driving the handle 16 to point to the tripping position.

[0240] At the same time, the first torsion arm 251 of the deflection torsion spring 25 that stores energy drives the actuator 3 to rotate along the first direction (counterclockwise) for a certain angle until the energy storage of the deflection torsion spring 25 is released. Then the energy storage element 21 continues to drive the actuator 3 to rotate along the first direction (counterclockwise), so that the actuator 3 continues to drive the first torsion arm 251 of the deflection torsion spring to rotate along the first direction (counterclockwise), driving the deflection torsion spring 25 to twist and store energy again (reverse torsion energy storage), thereby causing the second torsion arm 252 of the deflection torsion spring 25 to apply a torsional torque along the first direction (counterclockwise) to the sleeve 24.

[0241] Before the re-buckle energy storage process begins, the state of the deflection torsion spring 25 is reverse torsion energy storage (energy stored in the free tripping process). During the re-buckle energy storage process, the deflection torsion spring 25 changes from reverse torsion energy storage, releases energy, and then changes to forward torsion energy storage.

[0242] Before the free tripping process begins, the state of the deflection torsion spring 25 is forward torsion energy storage (energy stored in the re-tripping energy storage process). During the free tripping process, the state of the deflection torsion spring 25 changes from forward torsion energy storage, energy release, and then to reverse torsion energy storage.

[0243] The re-decoupling energy storage process and the free tripping process form a cyclic process.

[0244] Before re-decoupling and energy storage, the deflection torsion spring can store energy in a forward torsion direction; before free tripping, the deflection torsion spring can store energy in a reverse torsion direction; that is, the deflection torsion spring is a cyclic process; changing the rotation direction of the deflection torsion spring can achieve the opposite torque set in the deflection torsion spring in this embodiment, and can achieve the same effect. The purpose of the design of this embodiment is to take one of the following methods: the closed state of the electrical control system state switching unit is the normal use state of the electrical control system state switching unit; the closed state of the electrical control system state switching unit is the state of the deflection torsion spring in the forward torsion energy storage state.

[0245] The energy storage mechanism for the state switching operation of the electrical control system of the embodiment of the present invention can realize independent tripping and energy storage, that is, the tripping and energy storage process are independent of the internal energy storage element energy storage process of the electrical control system state switching unit operating mechanism. Before operating the electrical control system state switching unit operating mechanism, it is necessary to first perform re-tripping and energy storage of the tripping device. Only after re-tripping and energy storage can the electrical control system state switching unit operating mechanism be normally operated. That is, before operating the electrical control system state switching unit operating mechanism, the tripping device must first be re-tripped and energy stored. Before re-tripping and energy storage, closing and opening operations cannot be performed. This makes it easier, safer and more reliable to operate the electrical control system state switching unit operating mechanism. The energy storage mechanism for the state switching unit operation of the embodiment of the present invention also has a free tripping function. At the moment of closing the operating switch, if the handle 16 or the handle shaft is stuck, the tripping function can still be achieved, thereby improving the safety performance of the electrical control system state switching unit. In addition, the structure is simple, the function is stable, and the energy storage element energy release utilization rate is high. In addition, the closing process of the energy storage mechanism and the closing process of the electrical control system state switching unit operating mechanism are not performed simultaneously, so that the torsional torque of the energy storage process and the torsional torque of the closing process of the electrical control system state switching unit operating mechanism cannot be superimposed, avoiding the generation of a large operating torque.
