DETAILED DESCRIPTION

[0033] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples and cannot be used to limit the protection scope of the present invention.

[0034] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.

[0035] like Figure 1-11As shown, the isolating switch combination of the embodiment of the present invention includes at least two isolating switch bodies 1 and an operating mechanism for synchronously controlling all the isolating switch bodies 1, wherein the operating mechanism includes a rotating shaft 10 and linkage components 2 matched with the number of the isolating switch bodies 1, and each isolating switch body 1 is provided with an opening and closing drive mechanism, one end of the linkage component 2 is connected to the rotating shaft 10, and the other end of the linkage component 2 is connected to the opening and closing drive mechanism of the corresponding isolating switch body 1, so as to control the rotation of the rotating shaft 10 to drive the opening and closing drive mechanism to operate through the linkage component 2, thereby controlling the opening and closing actions of the isolating switch body 1.

[0036] By using the same operating mechanism to synchronously drive two or more isolating switch bodies 1, and each isolating switch body 1 driven is not limited to being able to perform a unified opening or closing, that is, the designed isolating switch combination can be adjusted accordingly according to different usage occasions. For example, when uniformly driven, part of the isolating switch bodies 1 can be designed to perform a closing operation structure according to needs, while part of the isolating switch bodies 1 can be designed to perform an opening operation structure, thereby greatly improving the adaptability of the present invention to various occasions. In addition, the driving of the operating mechanism can also be designed according to usage requirements. That is, if it is matched with an occasion that requires automatic control, a corresponding mechanism that can be used to rotate the rotating shaft 10 can be connected to the rotating shaft 10, and if it is used for In some occasions where manual drive is required, a handle 3 can be correspondingly set on the rotating shaft 10, so that the isolating switch group can be manually controlled. As a result, the isolating switch combination involved in the present invention can further improve the adaptability of occasions and meet different usage requirements. When the same operating mechanism is used for driving, the separation and closing process can be convenient to operate. At the same time, it can also avoid the situation similar to the existing situation that in certain specific occasions, in order to meet the usage requirements, it is sometimes necessary to install two or three isolating switches at the same position, and each isolating switch is equipped with an independent operating mechanism. In actual operation, the user can only perform separate separation and closing control of each isolating switch, which makes the operation more troublesome and reduces the user's usage experience in specific occasions.

[0037] like Figure 1-5As shown, in the design method of each isolating switch body 1 in the isolating switch combination involved in the present invention, since the operating mechanism used controls each isolating switch body 1, it is synchronously driven by the rotating shaft 10 cooperating with the linkage member 2. Therefore, in the design process of each isolating switch body 1, it is preferred to distribute all the isolating switch bodies 1 in a stacked manner, and the corresponding rotating shaft 10 is arranged along the stacking direction, so that the design convenience of the operating mechanism involved can also be improved accordingly, that is, one end of each linkage member 2 can be directly connected to the circumferential surface of the rotating shaft 10, and the other end is correspondingly connected to the opening and closing drive mechanism of each isolating switch body 1, so that when the rotating shaft 10 rotates, it can drive each linkage member 2 to rotate synchronously, and when it is transmitted to each isolating switch body 1, convenient synchronous opening and closing operation can be achieved.

[0038] like Figure 1-6 As shown, the isolating switch body 1 also includes a housing 11, a static contact 7 limited on the housing 11, a moving contact 8 corresponding to the static contact 7, and a contact frame 9 for mounting the moving contact 8, wherein the contact frame 9 is movably arranged in the housing 11; the opening and closing drive mechanism includes a contact opening and closing drive member 5 limited in the housing 11 and performing a circumferential swinging action, and a fast opening and closing drive mechanism 6, the contact opening and closing drive member 5 is linked with the contact frame 9, and a swinging portion 51 connected to the linkage member 2 is protruded on the contact opening and closing drive member 5, so as to realize that when the rotating shaft 10 rotates, the contact opening and closing drive member 5 is driven to swing through the linkage member 2, thereby driving the contact frame 9 to move; the fast opening and closing drive mechanism 6 is connected to the contact opening and closing drive member 5, and is designed to generate a morphological change of compressing the stored energy first and then releasing the stored energy during the swinging process of the contact opening and closing drive member 5; the isolating switch combination involved in the present invention can make the corresponding linkage feedback inside each isolating switch body 1 in the synchronous driving stage through the operating mechanism, thereby ensuring the design reliability of the present invention.

[0039] like Figure 1-6As shown, the contact separation and connection driving member 5 includes a limiting portion 52 for limiting the contact separation and connection driving member 5 in the housing 11, and the swinging portion 51. Each linkage member 2 includes a connecting plate 21 fixed to the rotating shaft 10, and a pulling plate 22 connected to the connecting plate 21 in a hinged manner. The end of the pulling plate 22 away from the connecting plate 21 is connected to the swinging portion 51. The rotating shaft 10 rotates to drive the pulling plate 22 to pull the swinging portion 51 to make the contact separation and connection driving member 5 swing. The swing shaft 511 is provided on the moving part 51, and the swing shaft 511 is connected to the contact frame 9. The design enables each linkage member 2 to drive the connecting plate 21 and the pulling plate 22 in sequence through the rotating shaft 10, and then drive the swing part 51 on the opening and closing drive mechanism to move through the driving force of the pulling plate 22. In the process of driving the swing part 51 to move, when it swings to a certain amplitude, the contact frame 9 can move accordingly, thereby realizing the convenient driving of the opening and closing process of the corresponding disconnector. In addition, in order to ensure To ensure reliable driving of the contact frame 9, a corresponding slide groove 91 can be provided on the contact frame 9 relative to the position toward the swinging portion 51, that is, after the swinging portion 51 extends into the slide groove 91 and the pull plate 22 pulls the swinging portion 51 to move, when it is pulled to a certain extent, the rapid opening and closing drive mechanism 6 is actuated, so that the swinging portion 51 quickly moves toward one side of the slide groove 91 and pushes the contact opening and closing drive member 5, thereby realizing the closing or opening of the disconnector body 1, and after the rotating shaft 10 is reversed, the pull plate 22 drives the swinging portion 51 to pull in the opposite direction, and at the same time, when it is pulled to a certain extent, the rapid opening and closing drive mechanism 6 also performs a corresponding rapid opening and closing action, so that the swinging portion 51 quickly moves toward the other side of the slide groove 91 and pushes the contact frame 9, thereby realizing the required opening and closing switching of the disconnector body 1, thereby further ensuring that the same operating mechanism involved in the disconnector combination can realize the reliable driving of the opening and closing of each disconnector body 1.

[0040] like Figure 2-7As shown, the fast opening and closing drive mechanism 6 includes a swing contact 63, an elastic member 62, and an opening and closing actuator 61. One end of the opening and closing actuator 61 faces the swing contact 63, and the other end abuts against the housing 11. The swing contact 63 includes a swing contact side and a penetration side 632. The swing contact side of the swing contact 63 faces the swing portion 51 of the contact opening and closing drive member 5, and a limiting groove 631 is formed on the swing contact side to be engaged with the swing portion 51. The swing contact 63 is connected to the opening and closing actuator through the penetration side 632. The design of the fast opening and closing drive mechanism 6 used in each isolating switch body 1 to ensure reliable opening and closing drive of the moving and static contacts, wherein the specific opening and closing process of the fast opening and closing drive mechanism 6 is as follows: when the rotating shaft 10 drives the connecting plate 21 and the pulling plate 22 to perform linkage action, the action of the pulling plate 22 can synchronously drive the swinging portion 51 of the contact opening and closing drive member 5, so that it swings when the swinging contact member 63 swings. The swing contact piece 63 moves on the limit slot 631 on the contact side, and the swing contact piece 63 moves in the direction of the opening and closing actuator 61, and at the same time drives the elastic piece 62 to compress and store energy. When the limit portion 52 and the swing portion 51 of the contact opening and closing driving member 5, and the swing contact piece 63 and the opening and closing actuator 61 on the fast opening and closing driving mechanism 6 are distributed on the same straight line, as the pull plate 22 continues to pull, the fast opening and closing driving mechanism 6 is unbalanced and turns, and the elastic force of the synchronous elastic piece 62 is instantly released, so that the swing contact piece 63 and the opening and closing actuator 61 on the fast opening and closing driving mechanism 6 are The actuator 61 moves rapidly in the direction in which the pull plate 22 is pulled, and causes the swinging portion 51 of the contact separation and closing driving member 5 to act on the contact frame 9, thereby enabling the disconnector to quickly separate and close the switch. Furthermore, when the rotating shaft 10 is reversed, the pull plate 22 pulls the swinging portion 51 of the moving contact separation and closing driving member 5 in the opposite direction of the previous separation and closing. When the rapid separation and closing driving mechanism 6 is unbalanced again, the disconnector can thereby achieve rapid separation and closing switching. At the same time, the preferred structural style of the above-mentioned limit slot 631 is an arc surface structure.

[0041] like Figure 2-3As shown, a limiting groove portion 111 is formed on one side of the shell 11 relative to the opening and closing actuator 61, and the end of the opening and closing actuator 61 relative to the swing contact 63 extends into the limiting groove portion 111 and interferes with the limiting groove portion 111. In the design scheme, for the other end of the opening and closing actuator 61 relative to the swing contact 63, its preferred structure may be a structure similar to a pointed angle, and the preferred structural style of the limiting groove portion 111 may be a design with an angle groove on the shell 11, thereby enabling the opening and closing actuator 61 to be reliably flipped in the shell 11 area when the rapid opening and closing drive mechanism 6 is unbalanced, thereby ensuring the reliability of the design of the present invention.

[0042] like Figure 2-7 As shown, the limiting portion 52 is a positioning column limited on the shell 11, the swinging portion 51 is sleeved on the positioning column, and the end of the pull plate 22 away from the chain plate is sleeved on the swing shaft 511 and forms a connection with the swinging portion 51; the contact separation and closing drive member 5 can be reliably limited in the shell 11, and the swinging portion 51 after limiting, that is, the swinging portion 51 can reliably swing around the position of the positioning column, and through the action of the swing shaft 511, the contact frame 9 can be reliably driven to move, thereby realizing reliable separation and closing drive of the disconnector and separation and closing switching action.

[0043] like Figure 2-7 As shown, a swing shaft blocking block 54 is formed on the swing portion 51 on the side away from the swing shaft 511, the swing shaft 511 is distributed on one side of the positioning column, and the swing shaft blocking block 54 is distributed on the other side of the positioning column. A swing shaft rotation amplitude limiting block 53 is formed on the positioning column on the side facing the swing shaft blocking block 54, and a swing shaft rotation amplitude limiting groove 531 is provided on the swing shaft rotation amplitude limiting block 53. The swing shaft blocking block 54 extends into the swing shaft rotation amplitude limiting groove 531 to limit the relative swing angle between the swing portion 51 and the limiting portion 52. This design can make the contact separation and closing driving member 5 designed by the present invention reliable and will not have a swing overtravel, that is, when the swing portion 51 slides on the limiting groove portion 111 and is in an unbalanced stage of the fast separation and closing driving mechanism 6, the swing portion 51 can be prevented from accidentally sliding out of the limiting groove portion 111 through the action of the swing shaft rotation amplitude limiting groove 531 and the swing shaft blocking block 54.

[0044] like Figure 8-11As shown, the operating mechanism also includes a fixing frame 20 and a handle 3, the fixing frame 20 is relatively fixed to the isolating switch body 1, the rotating shaft 10 is mounted on the fixing frame 20, the handle 3 is mounted on one end of the rotating shaft 10, and a panel 30 is fixed on the fixing frame 20 near the end of the handle 3; a rotation angle limiter 50 is fixed on the rotating shaft 10, and a limiting protrusion 201 is formed on the panel 30. When the rotating shaft 10 rotates to the limit position, the rotation angle limiter 50 abuts against the limiting protrusion 201 to form a stopper; when the isolating switch combination involved in the present invention is manually controlled, reliable driving can be achieved. At the same time, during use, the rotation angle limiter 50 and the limit protrusion 201 can be used to cooperate with each other to realize that when the handle 3 is rotated to a certain extent, the rotation angle limiter 50 and the limit protrusion 201 can cooperate to inform the user that the handle 3 has been rotated to the right position, thereby ensuring the reliability of the design of the present invention and further preventing the occurrence of overtravel. In addition, the upper sleeve 4 can also be involved in the rotating shaft 10, that is, when the connecting plate 21 extends to the rotating shaft 10, the connecting plate 21 can be clamped by the sleeve 4, thereby making it possible for the connecting plate 21 to be reliably set on the rotating shaft 10.

[0045] like Figure 8-11 As shown, a handle lock 40 is installed on the handle 3, and the handle lock 40 has a rotation stop portion 401 and a lock hole 402; a through hole 31 is opened in the area corresponding to the lock hole 402 on the handle 3, and a handle locking groove 202 is opened in the area corresponding to the rotation stop portion 401 on the panel 30. The handle lock 40 can move relative to the handle 3 to allow the rotation stop portion 401 to extend into or exit the handle locking groove 202. When the lock passes through the through hole 31 and the lock hole 402, the handle lock 40 is locked, so that the rotation stop portion 401 on the handle lock 40 is kept in the state of extending into or exiting the handle locking groove 202. This design can achieve the safety of the operating mechanism and the isolating switch combination during their use and prevent the occurrence of misoperation.

[0046] For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. However, these obvious changes or modifications derived from the essential spirit of the invention still fall within the scope of protection of the present invention.
