Description

Technical Field

[0001] The utility model relates to the technical field of electrical devices, in particular to an electric operating mechanism for a bipolar frame disconnecting switch. Background Art

[0002] A circuit controller refers to a master device that changes the wiring of the main circuit or control circuit and changes the resistance value in the circuit in a predetermined order to control the starting, speed regulation, braking, reverse or other specific actions of motors, electronic devices, etc. It usually consists of parts such as a program counter, instruction register, instruction decoder, timing generator, and operation controller. It is the "decision-making body" that issues commands and can coordinate and command the operation of the entire system. There are many types of circuit controllers, including but not limited to the following:

[0003] Logic controllers: including combinational logic controllers and microprogram controllers. The combinational logic controller is composed of logic circuits and completely relies on hardware to implement the functions of instructions. It is complex to design but has a fast execution speed; the microprogram controller is convenient to design, has a simple structure, and is relatively easy to modify or expand.

[0004] Timers: Control the switch of the circuit according to a preset time interval, and are divided into monostable timers and bistable timers. They are often used to control electronic clocks, electronic doorbells, timer switches, etc.

[0005] Flip-flops: Convert a short-time signal into a persistent switch state, and are divided into types such as RS flip-flops, D flip-flops, JK flip-flops, etc. They are often used in fields such as digital logic circuits, memories, counters, frequency dividers, etc.

[0006] Logic gates: Elements that implement digital logic operations, including AND gates, OR gates, NOT gates, XOR gates, etc., and are widely used in electronic computers, digital meters, electronic counters, etc.

[0007] Resistors and capacitors: Resistors control the circuit current and voltage by adjusting the resistance value, and capacitors are used to store electrical energy. Both are important components in the control circuit.

[0008] In the prior art, when controlling the closing and opening of a circuit, in the event of a circuit failure, due to the single manual or automatic control being extremely easy to damage, a single control method may not be able to timely switch the circuit state. To solve the above problems, we provide an electric operating mechanism for a bipolar frame disconnecting switch. Summary of the Utility Model

[0009] The technical problem to be solved by the present utility model is how, when a user wants to perform closing and opening operations on a circuit, the user can choose a manual or automatic operation method to drive a self-locking operation structure that requires a large driving force with a small driving force and thereby perform closing and opening operations on the circuit. A double-pole frame disconnecting switch electric operating mechanism is provided.

[0010] The technical solution adopted by the present utility model to solve its technical problems is: a double-pole frame disconnecting switch electric operating mechanism, including: a self-locking operation structure, a manual-automatic integrated operation mechanism.

[0011] An arc extinguishing structure is provided on the side of the manual-automatic integrated operation mechanism, and a wiring terminal is provided on the upper part.

[0012] The self-locking operation structure is arranged on the side of the manual-automatic integrated operation mechanism, is connected to the manual-automatic integrated operation mechanism, and is connected to the arc extinguishing structure.

[0013] When a user wants to perform closing and opening operations on a circuit, the user can choose to manually start or automatically start the manual-automatic integrated operation mechanism. After the manual-automatic integrated operation mechanism is started, the manual-automatic integrated operation mechanism can use a small driving force to start the self-locking operation structure. The self-locking operation structure controls the arc extinguishing structure to open or close, and the arc extinguishing structure can extinguish the arc generated when the circuit is opened or closed. Thereby, safe opening and closing control of the circuit is achieved.

[0014] In such a working mode, when a user wants to perform closing and opening operations on a circuit, the technical effect is achieved that the user can choose a manual or automatic operation method to drive a self-locking operation structure that requires a large driving force with a small driving force and thereby perform closing and opening operations on the circuit.

[0015] Further, the manual-automatic integrated operation mechanism includes: a driving motor, a planetary gear set, a main transmission shaft, a handle.

[0016] The driving motor is arranged below the wiring terminal and is fixedly arranged.

[0017] The planetary gear set is arranged below the driving motor and is connected to the rotating shaft of the driving motor through a gear structure.

[0018] The main transmission shaft is arranged below the driving motor, on the side of the planetary gear set. One end of the main transmission shaft is fixedly connected to the planetary gear set, and the other end is also connected to the self-locking operation structure.

[0019] The handle is sleeved on the main transmission shaft and is fixedly connected to the main transmission shaft.

[0020] When the user starts the drive motor, the rotation of the drive shaft of the drive motor can drive the main drive shaft to rotate together through the gear structure and the planetary gear set. The main drive shaft drives the handle to rotate, causing the handle to change from the initial position, thereby indicating the current circuit state.

[0021] When the user wants to manually close or open the circuit, the user can pull or push the handle to the initial position. When the handle moves, the handle will drive the main drive shaft to rotate at this time, so that the main drive shaft can drive the self-locking operation structure to rotate together, enabling the self-locking operation structure to control the arc extinguishing structure to close or open.

[0022] Furthermore, the planetary gear set includes: a sun gear, three planetary gears, a fixed plate, a planetary carrier, and an inner ring gear.

[0023] The fixed plate is fixedly arranged and parallel to the main drive shaft.

[0024] The axis of the sun gear coincides with the axis of the main drive shaft and is rotationally connected to the fixed plate through a rotating shaft. The rotating shaft of the sun gear is connected to the gear structure.

[0025] The three planetary gears are arranged around the sun gear and are rotationally connected to the fixed plate. The three planetary gears mesh with the sun gear.

[0026] The planetary carrier is arranged on the side of the three planetary gears and is rotationally connected to the three planetary gears.

[0027] The axis of the inner ring gear coincides with the axis of the main drive shaft. The inner ring gear is sleeved outside the three planetary gears and meshes with the three planetary gears. The inner ring gear is fixedly connected to the main drive shaft.

[0028] When the user starts the drive motor, the rotation of the drive shaft of the drive motor will drive the sun gear to rotate by driving the gear structure. The sun gear drives the three planetary gears to rotate. The rotation of the three planetary gears drives the inner ring gear to rotate. The inner ring gear drives the main drive shaft to rotate. The rotation of the main drive shaft drives the self-locking operation structure to start. By setting the planetary gear set, the self-locking operation structure can be started with a smaller driving force.

[0029] Furthermore, a number of anti-slip protrusions are provided on the surface of the handle.

[0030] The provision of anti-slip protrusions on the surface of the handle can prevent the user from accidentally slipping and touching other components and getting an electric shock during manual operation.

[0031] Furthermore, the connecting ring of the handle is provided as a hollow structure.

[0032] By setting the connecting ring of the handle as a hollow structure, the weight of the handle can be effectively reduced, so that the driving force provided by the sun gear to the main transmission shaft will not be weakened too much due to the weight of the handle, and at the same time, it is convenient for users to pull the handle more easily.

[0033] Furthermore, the handle, sun gear, three planet gears, fixed plate, planet carrier, inner ring gear, and main transmission shaft are respectively made of insulating materials.

[0034] By using insulating materials to make the handle, sun gear, three planet gears, fixed plate, planet carrier, inner ring gear, and main transmission shaft, it can be ensured that the driving motor will not be affected by external current during operation, thus preventing the driving motor from being damaged.

[0035] Advantages of the present utility model:

[0036] 1. Through the mutual cooperation and support between the self-locking gear structure and the manual-automatic integrated operation mechanism of the present utility model, users can choose to manually or automatically start the manual-automatic integrated operation mechanism, so as to drive the closing and opening control of the arc extinguishing structure through the self-locking gear structure. Similarly, when the user wants to perform closing and opening operations on the circuit, the user can choose to manually or automatically operate in a way that uses a relatively small driving force to drive the self-locking operation structure that requires a relatively large driving force, and thus perform closing and opening operations on the circuit.

After the manual-automatic integrated operation mechanism is started, the manual-automatic integrated operation mechanism can use a smaller driving force to start the self-locking operation structure. The self-locking operation structure controls the arc extinguishing structure to open or close, and the arc extinguishing structure can extinguish the arc generated when the circuit is opened or closed. In this way, the safe opening and closing control of the circuit is realized.

[0047] In this working mode, when the user wants to perform closing and opening operations on the circuit, the user can choose the manual or automatic operation mode to drive the self-locking operation structure that requires a larger driving force with a smaller driving force and thereby perform closing and opening operations on the circuit.

[0064] The connecting ring of the handle 4 is set as a hollow structure.

[0065] By setting the connecting ring of the handle 4 as a hollow structure, the weight of the handle 4 can be effectively reduced, so that the driving force provided by the sun gear 5 to the main transmission shaft 3 will not be weakened too much due to the weight of the handle 4, and at the same time, it is convenient for the user to pull the handle 4 more easily.

[0066] The handle 4, sun gear 5, three planet gears 6, fixed plate 7, planet carrier 8, inner ring gear 9, and main transmission shaft 3 are respectively made of insulating materials.
