Description

Technical Field

[0001] The utility model relates to the technical field of circuit breakers, and more specifically to a direct-controlled switch mechanism. Background Art

[0002] Traditional 380V low-voltage molded case circuit breakers and 10KV medium-voltage circuit breakers (pole switches) are based on multi-link spring operating mechanisms, whose main function is protection, that is, once leakage (low voltage), short circuit, overload and other faults occur, they are immediately and quickly disconnected, requiring them to have the ability to quickly disconnect short-circuit currents. The opening process of this mechanism is very fast, and the spring force separates the contacts, but its closing is also based on the spring, which requires energy storage at ordinary times. The energy storage process takes a certain amount of time, which results in the inability of switches of this type of mechanism to achieve controlled rapid opening and closing operations.

[0003] In response to this situation, some manufacturers have launched low-voltage and medium-voltage circuit breakers based on the principles of permanent magnet mechanisms and magnetic control mechanisms that can be quickly opened and closed. Due to the use of new magnetic materials, their rapid magnetic control characteristics have been improved to a certain extent. They are currently collectively referred to as magnetic control circuit breakers. Whether it is a low-voltage or medium-voltage magnetic control circuit breaker, its closed state is maintained by relying on the magnetic attraction principle to tightly attract the moving and static contacts. The steady state of this attraction state is affected by many factors and is a non-locking connection. Under the influence of factors such as vibration, temperature rise, etc. that induce demagnetization of the magnet, the loose fit between the contact surfaces of the moving and static contacts, and the electric disassembly force of instantaneous large currents, the moving and static contacts are easily disengaged, that is, the so-called "sneak jump" phenomenon occurs. In fact, the phenomenon of sneak jump of this type of switch during application is common.

[0004] The existing Chinese patent with announcement number CN212517024U discloses a fast-acting magnetically controlled vacuum circuit breaker, including an isolating switch assembly, a sealed pole assembly, a magnetic control mechanism and a box assembly; the isolating switch assembly includes a moving blade, a stationary blade and an operating handle, the operating handle is used to control the movement of the moving blade, so that the moving blade is connected or disconnected with the stationary blade to achieve closing or opening; the sealed pole assembly is used to realize the transmission of the magnetic control mechanism and the isolating switch assembly; the magnetic control mechanism is used to drive the moving blade to move, so that the moving blade is connected or disconnected with the stationary blade to achieve closing or opening; the magnetic control mechanism is arranged inside the box assembly, and the sealed pole assembly is arranged on the upper part.

[0005] Although the above-mentioned prior art provides a magnetically controlled pole-mounted vacuum circuit breaker, it is necessary to maintain the magnetic force to stabilize the closed state when closing the circuit. As a result, when closing the circuit, if there is an impact of external environmental factors or the impact of current on the magnetic pole, the permanent magnet will not be able to provide stable and continuous magnetic force, causing the switch to still be prone to tripping. Since medium-voltage pole-mounted switches are used in distribution power grids, when tripping occurs, it is easy to cause great losses to the operation of the entire power grid. In this regard, the present application provides a directly controlled switch, which has the function of self-locking after closing the circuit, so that the closed state can be stably maintained when closing the circuit, and a weak current control unlocking is provided when opening the circuit, and rapid opening is achieved.

[0023] 1. The magnetic control unit is controlled to close or open by energizing the coil in the magnetic control assembly. When closing or opening, due to the overall structural setting, only a short current needs to be provided to the coil. When the closing or opening movement is completed, the coil can be stopped from being energized, avoiding the need to continuously energize the coil to keep the switch closed. When the switch is closed, an electromagnetic force is generated after the coil is energized. The moving core is driven by the electromagnetic force to close the magnetic control unit. At this time, the electromagnetic controller in the direct control assembly pushes the direct control push plate to move, and the direct control push plate pushes the lock body downward, so that when the magnetic control unit moves to the position corresponding to the lock tongue and the locking part, the lock tongue is locked with the locking part under the action of the direct control push plate and the reset part, achieving the effect of mechanical interlocking and limiting the magnetic control unit to maintain a stable closing state.

The lock body is reset by the reset elastic member and separated from the locking part. At this time, the reverse current during closing is passed through the coil, so that the direction of the electromagnetic force received by the moving core changes. Under the action of the electromagnetic force, the moving core is pushed to open the gate, driving the magnetic control unit to open the gate.

[0038] In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits detailed descriptions of known functions and known components.

[0039] refer to Figures 1 to 10As shown, a specific implementation of a direct-controlled switch mechanism of the utility model is shown. The direct-controlled switch mechanism of the present application is applied to a pole-mounted circuit breaker. The pole-mounted circuit breaker includes a circuit breaker box 7 and a sealed pole assembly 8. The sealed pole assembly 8 is arranged on the circuit breaker box 7. The sealed pole assembly 8 includes a pole shell 41, a vacuum arc extinguishing chamber and an insulating rod. The pole shell 41 is connected to the circuit breaker box 7. The vacuum arc extinguishing chamber is arranged in the pole shell 41 to provide a vacuum arc extinguishing environment. The insulating rod is arranged in the pole shell 41 and one end extends into the circuit breaker box 7. One end of the insulating rod extending into the circuit breaker box 7 is connected to the direct-controlled switch mechanism. The direct-controlled switch mechanism is used to control the insulating rod to limit and lock the position of the insulating rod when performing closing control, and release the lock of the insulating rod when opening is required to allow the insulating rod to perform opening movement.

[0040] The direct-control switch mechanism includes a direct-control link 1, a self-locking component 2, a direct-control component 3 and a magnetic control component 4. A shell 41 is provided in the circuit breaker box 7. The magnetic control component 4 is installed in the shell 41. A bracket 23 is also connected to one side of the shell 41. The self-locking component 2 and the direct-control component 3 are connected to the bracket 23. The direct-control link 1 includes a magnetic control component 11 and a direct control component 12. One end of the magnetic control component 11 is threadedly connected to the sealed pole component 8. The end of the magnetic control component 11 away from the sealed pole component 8 is connected to the direct control component 12 through a fastener 5. In this application, the fastener 5 is selected as a bolt, and the bolt is used to The direct control 12 is connected to the magnetic control 11, and a coil 43 is arranged inside the magnetic control component 4. The magnetic control component 4 provides electromagnetic force to control the magnetic control 11 to close or open the switch through the coil 43, thereby controlling the magnetic control 11 to close and open the switch. The self-locking component 2 includes a lock body 21 and a lock tongue 22. The lock body 21 is connected to the direct control 12, and the lock tongue 22 is connected to the lock body 21. A lock groove 13 for the lock tongue 22 to lock is provided in the magnetic control 11. The direct control component 3 is used to provide a driving force to push the lock body 21 to move and drive the lock tongue 22 and the lock groove 13 to lock or unlock. When the coil 43 is energized to provide an electromagnetic force to control the closing movement of the magnetic control 11, the magnetic control 11 drives the direct control 12 to move, the direct control component 3 pushes the lock body 21 to move, and drives the lock tongue 22 to be stuck in the lock slot 13, so that when the closing is completed, there is no need to continue to energize the coil 43 to maintain the electromagnetic force, and a stable closing lock is provided by the limit locking method of the lock tongue 22 and the lock slot 13, thereby maintaining a stable closing state, and it is not easy to have a "sneak jump" phenomenon, and the purpose of maintaining a stable closing is achieved through a mechanical interlocking method. When the coil 43 is reversely energized, an electromagnetic force is provided to control the opening movement of the magnetic control 11, and the lock body 21 is driven to move under the action of the direct control component 3, so as to drive the lock tongue 22 to disengage from the lock slot 13, so as to achieve the effect of unlocking the magnetic control 11, so that the magnetic control 11 can perform the opening movement, achieving the effect of facilitating the control of closing or opening, and having the effect of stable closing when closing, thereby improving the safety of the overall column-mounted circuit breaker.

[0041] The magnetic control assembly 4 also includes a moving core 42, a winding cavity is formed on the shell 41, and the coil 43 is arranged in the winding cavity. A core cavity is formed in the shell 41, and the moving core 42 is arranged in the core cavity. The moving core 42 is connected to the magnetic control component 11, and the coil 43 is energized to provide electromagnetic force to control the moving core 42 to close or open the switch along the core cavity, so as to drive the magnetic control component 11 to move axially along the shell 41. When the closing or opening movement control is performed, it is only necessary to energize the coil 43 for a short time and with a small current to control the closing or opening movement of the moving core 42. When the closing or opening is completed, the coil 43 can be de-energized. This not only provides stable closing and opening movement control, but also reduces the energy consumption when maintaining the closing.

[0042] A winding shaft 24 for connecting the lock body 21 is provided on the bracket 23, and a movable groove 14 is opened on the direct control part 12. The winding shaft 24 is inserted into the movable groove 14. When the magnetic control part 11 moves and drives the direct control part 12 to move, the winding shaft 24 moves along the movable groove 14, so that when the closing or opening movement is performed, the winding shaft 24 is not easy to hinder the movement of the direct control part 12, and the movable groove 14 can also play the effect of guiding and limiting the winding shaft 24.

[0043] The self-locking component 2 also includes a reset member 25 and a reset elastic member 26. The reset member 25 is connected to the lock body 21. The reset elastic member 26 is connected to the connection between the reset member 25 and the lock body 21. The outer wall of the magnetic control unit 11 is provided with a push flange 15. When the magnetic control unit 4 drives the magnetic control unit 11 to close the switch, the push flange 15 contacts the reset member 25 and provides a downward pressure on the reset member 25. The reset elastic member 26 is deformed and stored by the downward pressure. When the magnetic control unit 4 drives the magnetic control unit 11 to open the switch, the reset elastic member 26 is deformed and stored. Component 26 releases elastic force to assist in driving the reset component 25 to reset and drive the lock body 21 to reset. Under the action of the reset component 25 and the reset elastic component 26, the reset elastic component 26 is deformed and stores force when the closing movement is performed. When the opening movement is performed, the reset elastic component 26 provides elastic force to assist the lock body 21 and the lock tongue 22 to reset. When the opening movement is performed, the lock tongue 22 can quickly separate from the lock slot 13, releasing the limit on the magnetic control component 11, so that the magnetic control component 11 can quickly open the door.

[0044] The lock slot 13 on the magnetic control 11 includes a locking portion 131 and a yielding portion 132. The yielding portion 132 is opened along the axial direction of the magnetic control 11. The locking portion 131 is located at the end of the yielding portion 132 and forms a stepped groove with the locking portion 131. The direct control component 3 includes an electromagnetic controller 31 and a direct control push plate 32. A rotating shaft 33 is provided on the inner wall of the bracket 23. The direct control push plate 32 is arranged in the bracket 23 and is rotatably connected to the rotating shaft 33. The reset member 25 is between the rotating shaft 33 and the magnetic control 11. The magnetic control 11 is inserted into the direct control push plate 32. The electromagnetic controller 31 is arranged outside the bracket 23 and is used to provide a driving force to push the direct control push plate 32 to rotate along the rotating shaft 33. A tower spring 35 is also provided on the electromagnetic controller 31, and the tower spring 35 is arranged between the direct control push plate 32 and the electromagnetic controller 31. When closing the switch, the electromagnetic controller 31 pushes the direct control push plate 32 to rotate around the connection with the rotating shaft 33, and pushes the lock body 21 to move, so as to drive the lock tongue 22 to press down and lock with the locking part 131 in the lock groove 13. When locking and limiting, due to the closing movement of the magnetic control unit 11, the lock tongue 22 moves along the yielding part 132 to the locking part 131, and the lock tongue 22 is locked with the locking part 131 after being pressed down by the lock body 21, thereby achieving the effect of mechanical interlocking after closing the switch, and after interlocking, the lock body 21 is located in the plate groove 34 of the direct control push plate 32, thereby improving the stability of the limit locking of the lock body 21. When opening the switch, the electromagnetic controller 31 pulls the direct control push plate 32 to reset and compresses the tower spring 35, so that the tower spring 35 is in a compressed deformation and force storage state, providing auxiliary elastic force for pushing the direct control push plate 32 when closing the switch again. Under the action of the electromagnetic controller 31, the direct control push plate 32 is separated from the lock body 21, and the downward pressure on the lock body 21 is released. At this time, the reset elastic member 26 releases the elastic force to assist in driving the lock body 21 to reset, so as to drive the lock to separate from the locking part 131, thereby releasing the limit on the magnetic control unit 11, so that the magnetic control unit 11 can move to open the switch.

[0045] A damping member 6 is also sleeved on one end of the direct control 12 away from the magnetic control 11. The damping member 6 is used to provide a damping force when closing or opening the switch, so as to reduce the vibration of the entire circuit breaker box 7 when closing or opening the switch.

[0046] Working principle and its effect:

[0047] The magnetic control component 11 is controlled to close or open by energizing the coil 43 in the magnetic control component 4. When closing or opening the switch, due to the setting of the overall structure, only a short current needs to be provided to the coil 43. When the closing or opening movement is completed, the power supply to the coil 43 can be stopped, thereby avoiding the need to continuously energize the coil 43 to keep the switch closed. When the closing movement is performed, the coil 43 generates electromagnetic force after being energized, and the moving core 42 is driven by the electromagnetic force to drive the magnetic control unit 11 to close the switch. At this time, the electromagnetic controller 31 in the direct control component 3 pushes the direct control push plate 32 to move, and the direct control push plate 32 pushes the lock body 21 downward, so that when the magnetic control unit 11 moves to the position where the lock tongue 22 corresponds to the locking part 131, the lock tongue 22 is locked with the locking part 131 under the action of the direct control push plate 32 and the reset member 25, thereby achieving the effect of mechanical interlocking and limiting the magnetic control unit 11 to maintain a stable closing state. At this time, the coil 43 remains stably closed even when it is powered off, so that the "sneak jump" phenomenon is not easy to occur.

[0048] When the opening movement is performed, the electromagnetic controller 31 pulls the direct control push plate 32 to reset, and the downward pressure and limit on the lock body 21 are released. The lock body 21 is reset by the reset elastic member 26 and separated from the locking part 131. At this time, the reverse current during closing is passed through the coil 43, so that the direction of the electromagnetic force received by the moving core 42 changes, and the moving core 42 is pushed to open the gate under the action of the electromagnetic force, driving the magnetic control unit 11 to open the gate. At this time, the lock tongue 22 moves along the yielding part 132, and the limit on the magnetic control unit 11 is released, thereby realizing rapid opening movement control, realizing mechanical interlocking during closing, so as to maintain a continuous and stable closing state, and being able to perform rapid opening control.
