Description

Technical Field

[0001] This application relates to the field of isolating grounding switch technology, and in particular to a magnetic induction control mechanism suitable for isolating grounding switches. Background Technology

[0002] Among the various devices in a smart substation, the isolating grounding switch is a key device for ensuring the safe operation of the power system. The accuracy and reliability of its opening and closing operations are directly related to the stability of the power grid and the safety of personnel and equipment. Existing isolating grounding switches typically use a single-motor three-position operating mechanism that uses a spring structure to transmit the opening or closing position signal. In actual operation, due to the change in elastic force of the spring during the extension and contraction process, as well as the characteristics of the mechanical structure itself, severe vibrations will inevitably occur. The severe vibrations generated by the spring structure will cause fluctuations and distortions in the signal transmission process, making it difficult for the control system to accurately obtain the switch status. This makes it impossible for operators to accurately know whether the isolating grounding switch has been successfully switched to the corresponding position according to the instructions. Summary of the Invention

[0003] In view of this, this application proposes a magnetic induction control mechanism suitable for isolating grounding switches, comprising: a mechanism, a motor, a transmission device, a cam, a magnetic induction accessory, and a sensor module;

[0004] The mechanism has a main shaft and an output shaft, which are linked together. One end of the main shaft passes through the upper plate of the mechanism, and a cam is fixed on the main shaft. One end of the output shaft passes through the lower plate of the mechanism. It is suitable for driving the DSE mechanism to perform closing or opening operations.

[0005] The motor is fixed on one side of the mechanism, the transmission device is installed inside the mechanism, and the output end of the motor is connected to the main shaft through the transmission device.

[0006] The magnetic induction attachment is fixedly mounted on the cam so that it rotates with the rotation of the cam. The sensor module is fixedly mounted on the upper plate of the mechanism and is arranged adjacent to the magnetic induction attachment to sense the change of magnetic field in the space where the sensor module is located during the rotation of the magnetic induction attachment, thereby controlling the corresponding sensor in the sensor module to turn on or off according to the change of magnetic field.

[0007] In one possible implementation, the sensor module includes: an isolation closing magnetic induction sensor, an isolation grounding opening magnetic induction sensor, and a grounding closing magnetic induction sensor;

[0008] The isolation closing magnetic induction sensor, the isolation grounding opening magnetic induction sensor, and the grounding closing magnetic induction sensor are arranged circumferentially along the cam.

[0009] In one possible implementation, the transmission device includes: a reduction gear, a bevel gear, a transmission gear, a oscillating sector gear, and a driven sector gear;

[0010] The reduction gear is fixedly mounted on the output end of the motor, and meshes with the bevel gear. The transmission gear also meshes with the bevel gear, and the oscillating sector gear is fixedly mounted on the transmission gear.

[0011] The driven sector gear is mounted on the main shaft, and the driven sector gear is meshed with the oscillating sector gear.

[0012] In one possible implementation, a limiting shaft is also included; a limiting groove is provided on the transmission gear, and the limiting groove is positioned opposite to the opening of the oscillating sector gear; the limiting shaft is fixedly installed inside the mechanism, and one end of the limiting shaft passes through the limiting groove of the transmission gear.

[0013] In one possible implementation, a sector gear is also included; the sector gear is mounted on the main shaft and meshes with the output shaft.

[0014] In one possible implementation, an auxiliary switch is also included; the auxiliary switch is fixedly mounted on one side of the mechanism, and the trigger end of the auxiliary switch is connected to the output shaft via a connecting rod.

[0015] In one possible implementation, a locating pin is also included; one end of the main shaft away from the cam is disposed through the lower plate of the movement, and the locating pin is fixedly disposed on the main shaft and located at the end of the main shaft away from the cam.

[0016] Beneficial effects of this application

[0017] Compared with existing technologies, this application, by setting up a magnetic induction attachment and a sensor module, achieves precise cooperation between the magnetic induction attachment and the sensor module. The magnetic induction attachment rotates with the cam on the main shaft to the position of the corresponding sensor in the sensor module. At this time, the corresponding sensor in the sensor module detects the change in the magnetic field generated by the magnetic induction attachment and, based on the change in the magnetic field, enables the corresponding sensor to achieve circuit conduction. The conducted sensor generates an electrical signal and uploads it to the remote terminal. Thus, by cooperating with the magnetic induction attachment and the sensor module, the spring structure in conventional technology is replaced, thereby avoiding signal interference caused by spring vibration. This allows the control system to accurately obtain the opening and closing status of the isolating grounding switch, improving the accuracy of status detection. The magnetic induction attachment and the sensor module adopt the non-contact magnetic induction principle, achieving circuit conduction and signal upload through close-range magnetic induction based on the change in the magnetic field caused by the operation of the isolating grounding switch. There are no cables connected to the rotating parts of the DSE mechanism, eliminating the hidden dangers of cables swinging and entangled in the DSE mechanism, avoiding equipment failures and safety accidents that may be caused by cable problems, and ensuring the stable operation of the equipment.

[0018] By setting an auxiliary switch, which is connected to the output shaft via mechanical transmission to obtain status information, and by combining the detection methods with the magnetic attachment and sensor module, the dual-confirmation mechanism from different sources increases the reliability and accuracy of the system, avoiding erroneous operation or false status alarms caused by failure or misjudgment due to a single detection method.

Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0031] This application proposes a magnetic induction control mechanism for a grounding switch (DSE), comprising: a core 100, a motor 200, a transmission device 300, a cam 410, a magnetic induction accessory 420, and a sensor module; the core 100 contains a main shaft 110 and an output shaft 120, which are linked together; one end of the main shaft 110 passes through the upper plate 101 of the core 100; the cam 410 is fixedly mounted on the main shaft 110; one end of the output shaft 120 passes through the lower plate 102 of the core 100, and is suitable for driving the DSE mechanism to perform closing or opening operations; the motor 200... The motor 200 is fixed on one side of the mechanism 100, the transmission device 300 is installed inside the mechanism 100, and the output end of the motor 200 is connected to the main shaft 110 through the transmission device 300. The magnetic induction attachment 420 is fixedly mounted on the cam 410 so that the magnetic induction attachment rotates with the rotation of the cam 410. The sensor module is fixedly mounted on the upper plate 101 of the mechanism 100 and is arranged adjacent to the magnetic induction attachment 420 to sense the change of magnetic field of the space where the sensor module is located during the rotation of the magnetic induction attachment, so as to control the corresponding sensor in the sensor module to be turned on or off according to the change of magnetic field.

[0032] It should be noted that the mechanism 100 is used to provide an installation foundation and operating space for the control mechanism; the main shaft 110 and the output shaft 120 are linked to ensure synchronous power transmission, so that the motion state of the output shaft 120 is consistent with that of the main shaft 110; one end of the output shaft 120 passes through the lower plate 102 of the mechanism 100, and the DSE mechanism is fixedly mounted on the output shaft 120. The output shaft 120 is used to drive the DSE mechanism to perform closing or opening operations; a fixing plate 210 is provided on the side wall of the mechanism 100, and the motor 200 is fixedly mounted on the fixing plate 210. The motor 200 is used to provide stable power for the control mechanism. The transmission device 300 is installed inside the mechanism 100 and located between the output end of the motor 200 and the main shaft 110. The transmission device 300 is used to transmit the power output by the motor 200 to the main shaft 110, so that the main shaft 110 can rotate at a predetermined speed and direction. The cam 410 is fixedly mounted on... On the main spindle 110, the cam 410 is used to provide a mounting base for the magnetic induction accessory 420, which is firmly fixed on the cam 410. The magnetic induction accessory 420 moves with the rotation of the cam 410 to generate or sense changes in the magnetic field and works in conjunction with the sensor module. The sensor module is used to detect changes in the magnetic field generated by the rotation of the magnetic induction accessory 420. When the magnetic induction accessory 420 rotates to a specific position with the cam 410, the corresponding sensor in the sensor module detects the change in the magnetic field and generates a corresponding induced electromotive force, thereby realizing the conduction of the corresponding sensor circuit in the sensor module. After the corresponding sensor circuit in the sensor module is conducted, an electrical signal is generated. At the same time, the sensor in the sensor module with the circuit conducted uploads the generated electrical signal to the remote terminal. The remote terminal judges the status of the isolation grounding switch based on the received electrical signal and performs subsequent operations. In this system, the ground closing, isolation closing, and isolation grounding opening states of the DSE mechanism are always synchronized with the states detected by the sensor module. Specifically, when the magnetic induction accessory 420 rotates with the cam 410 to the ground closing position, the corresponding sensor in the sensor module detects the change in magnetic field and activates its circuit, thereby generating an electrical signal indicating the ground closing state. At this time, the main shaft 110 is in the position corresponding to the ground closing state. Due to the linkage mechanism between the main shaft 110 and the output shaft 120, the output shaft 120 is also in the position corresponding to the ground closing state. Therefore, the overall state of the DSE mechanism is also the ground closing state. Similarly, when the cam 410 rotates to the isolation closing or isolation grounding opening position, the corresponding sensor in the sensor module will also detect the change in magnetic field state and generate a corresponding electrical signal, ensuring that the state of the DSE mechanism is consistent with the state detected by the sensor module.

[0033] When the DSE mechanism performs the required operation, the motor 200 is started. The power output by the motor 200 is transmitted to the main shaft 110 through the transmission device 300. The main shaft 110 and the output shaft 120 rotate synchronously. The magnetic induction accessory 420 rotates with the cam 410 on the main shaft 110 to the position of the corresponding sensor in the sensor module. At this time, the corresponding sensor in the sensor module detects the change in the magnetic field generated by the magnetic induction accessory 420 and realizes the circuit conduction of the corresponding sensor based on the magnetic induction principle. (Where the magnetic induction principle refers to: when the magnetic field changes, the corresponding sensor in the sensor module generates a corresponding induced electromotive force based on the change in the magnetic field, thereby realizing the conduction of the circuit of the corresponding sensor in the sensor module.) After conduction, the sensor generates an electrical signal and uploads it to the remote terminal. The remote terminal judges the status of the isolation grounding switch based on the received electrical signal and performs subsequent operations. This application ensures that the signal detected by the sensor module is strictly consistent with the actual state of the DSE mechanism by linking the main shaft 110 and the output shaft 120.

[0034] Compared with the prior art, this application, by setting up a magnetic induction attachment 420 and a sensor module, achieves precise cooperation between the magnetic induction attachment 420 and the sensor module. The magnetic induction attachment 420 rotates with the cam 410 on the main shaft 110 to the position of the corresponding sensor in the sensor module. At this time, the corresponding sensor in the sensor module detects the change in the magnetic field generated by the magnetic induction attachment 420 and, based on the change in the magnetic field, enables the corresponding sensor to achieve circuit conduction. After conduction, the sensor generates an electrical signal and uploads it to the remote terminal. Thus, the cooperation between the magnetic induction attachment and the sensor module replaces the spring structure in conventional technology, thereby avoiding signal interference caused by spring vibration. This allows the control system to accurately obtain the opening and closing status of the isolating grounding switch, improving the accuracy of status detection. The magnetic induction attachment 420 and the sensor module adopt a non-contact magnetic induction principle, achieving circuit conduction and signal upload through close-range magnetic induction based on the change in the magnetic field caused by the operation of the isolating grounding switch. There are no cables connected to the rotating parts of the DSE mechanism, eliminating the hidden dangers of cables swinging and entangled in the DSE mechanism, avoiding equipment failures and safety accidents that may be caused by cable problems, and ensuring the stable operation of the equipment.

[0035] Furthermore, a preset distance is provided between the magnetic induction accessory 420 and the sensor module. By setting the preset distance, the sensor module can operate within the optimal magnetic field strength range, thereby ensuring the measurement accuracy of the magnetic field changes of the magnetic induction accessory 420 by the sensor module, reducing electromagnetic interference between the magnetic induction accessory 420 and the sensor module from surrounding components, ensuring that the signal received by the sensor module is true and reliable, and thus improving the stability and accuracy of the entire monitoring system.

[0036] Furthermore, the preset distance ranges from 8mm to 12mm, and preferably, the preset distance is 10mm.

[0037] Furthermore, the magnetic induction accessory 420 can be an electromagnetic coil or a permanent magnet, etc.

[0038] In one possible implementation, the sensor module includes: an isolation closing magnetic induction sensor 431, an isolation grounding opening magnetic induction sensor 432, and a grounding closing magnetic induction sensor 433; the isolation closing magnetic induction sensor 431, the isolation grounding opening magnetic induction sensor 432, and the grounding closing magnetic induction sensor 433 are arranged circumferentially along the cam 410.

[0039] It should be noted that the isolation grounding trip magnetic induction sensor 432 is located between the isolation closing magnetic induction sensor 431 and the grounding closing magnetic induction sensor 433. The three magnetic induction sensors, distributed circumferentially along the cam 410, fully utilize the space around the cam 410, avoiding mutual interference between sensors. These three sensors precisely correspond to specific positions of the cam 410 at different operating stages. Each time the cam 410 rotates to a specific angle, the corresponding magnetic induction sensor accurately detects the change in magnetic field, achieving precise positioning and monitoring of different operating states such as isolation closing, isolation grounding tripping, and grounding closing. Furthermore, each magnetic induction sensor operates independently, responsible for detecting different operating states without interference. This ensures accurate and reliable detection results for each operating state, preventing misjudgments due to the influence of other operations.

[0040] Furthermore, the setting positions of the isolation closing magnetic induction sensor 431, the isolation grounding opening magnetic induction sensor 432, and the grounding closing magnetic induction sensor 433 are consistent with the operating positions of the DSE mechanism, thereby ensuring that the signals detected by the three sensors are consistent with the actual state of the DSE mechanism, and ensuring that the detection results are accurate and reliable.

[0041] Furthermore, such as Figure 4 As shown, the isolation closing magnetic induction sensor 431, the isolation grounding opening magnetic induction sensor 432, and the grounding closing magnetic induction sensor 433 are respectively connected to the remote terminal via cable 4304. Each sensor corresponds to a specific interface on the remote terminal. Specifically, when the isolation closing magnetic induction sensor 431 is turned on due to a change in the external magnetic field or when the preset triggering condition is met, the electrical signal is transmitted to the corresponding interface on the remote terminal via cable 4304, thereby triggering the associated isolation closing status indicator light to light up.

[0042] Furthermore, the isolation closing magnetic induction sensor 431, the isolation grounding opening magnetic induction sensor 432, and the grounding closing magnetic induction sensor 433 all include: a glass tube 4301, a spring sheet 4302, and a contact 4303; the spring sheet 4302 and the contact 4303 are arranged opposite each other inside the glass tube 4301, and the contact 4303 must be located in a position that can be reached after the spring sheet 4302 is deformed. When the magnetic induction accessory 420 rotates to a specific position, the spring sheet 4302 in the corresponding sensor deforms and contacts the contact 4303 to realize the circuit conduction of the corresponding sensor and generate an electrical signal. The electrical signal is transmitted to the back-end terminal through the cable 4304 to make the corresponding indicator light on the back-end terminal light up.

[0043] Furthermore, the spring sheet is made of a ferromagnetic material.

[0044] In one possible implementation, the transmission device 300 includes: a reduction gear 310, a bevel gear, a transmission gear 330, an oscillating sector gear 340, and a driven sector gear 350; the reduction gear 310 is fixedly installed on the output end of the motor 200, the reduction gear 310 is meshed with the bevel gear, the transmission gear 330 is meshed with the bevel gear, the oscillating sector gear 340 is fixedly mounted on the transmission gear 330, and the driven sector gear 350 is sleeved on the main shaft 110, and the driven sector gear 350 is meshed with the oscillating sector gear 340.

[0045] It should be noted that the reduction gear 310 is fixedly installed at the output end of the motor 200, and the bevel gear is fixedly installed on the transmission shaft 323 inside the mechanism 100. The bevel gear and the reduction gear 310 are meshed together. The bevel gear is suitable for changing the transmission direction of the output power of the reduction gear 310, realizing the transmission of power between different planes, thereby effectively utilizing the internal space of the mechanism 100 and making the overall structure more compact. The transmission gear 330 meshes with the bevel gear, and the transmission gear 330 receives the power transmitted by the bevel gear and rotates, thereby driving the oscillating fan gear 340 to rotate. The driven sector gear 350 meshes with the oscillating sector gear 340, receiving power transmitted from the oscillating sector gear 340, driving the main shaft 110 to rotate, thereby achieving synchronous rotation of the main shaft 110 and the output shaft 120, and driving the DSE mechanism to perform closing or opening operations. The power of the oscillating sector gear 340 is accurately transmitted to the main shaft 110, so that the main shaft 110 and the output shaft 120 rotate at a predetermined speed and direction, realizing precise control of the DSE mechanism and precise detection of the status of the isolating grounding switch, ensuring the accuracy and reliability of the operation of the isolating grounding switch.

[0046] Furthermore, the bevel gear includes a first gear 321 and a second gear 322. The first gear 321 is coaxially connected to the reduction gear 310, and the planes containing the first gear 321 and the second gear 322 are perpendicular to each other. The second gear 322 is fixedly sleeved on the transmission shaft 323 and meshes with the first gear 321. The design of the first gear 321 and the second gear 322 being perpendicular to each other and meshing with each other realizes the change of the direction of the output power of the reduction gear 310.

[0047] Furthermore, motor 200 adopts a servo motor as used in existing technology.

[0048] In one possible implementation, a limiting shaft 332 is also included; a limiting groove 333 is provided on the transmission gear 330, and the limiting groove 333 is disposed opposite to the opening of the oscillating fan gear 340; the limiting shaft 332 is fixedly disposed inside the movement 100, and one end of the limiting shaft 332 passes through the limiting groove 333 of the transmission gear 330.

[0049] It should be noted that the limiting shaft 332 is used to limit the swing of the transmission gear 330. By cooperating with the upper limit groove 333 of the transmission gear 330, the swing range of the transmission gear 330 is limited. When the transmission gear 330 rotates with the drive of the motor 200 and the transmission of other gears, the limiting shaft 332 will move within the limiting groove 333. When it reaches the end of the limiting groove 333, it will stop the transmission gear 330 from continuing to swing, ensuring that its swing angle is within the design requirements. This ensures that the DSE mechanism can accurately reach the position when performing closing or opening operations, avoiding operational errors caused by excessive swing or positional deviation of the transmission gear 330.

[0050] In one possible implementation, a sector gear 111 is also included; the sector gear 111 is sleeved on the main shaft 110 and meshes with the output shaft 120. It should be noted that the sector gear 111 is designed to rotate synchronously with the main shaft 110 and, through its meshing connection with the output shaft 120, transmits power to the output shaft 120, thereby achieving synchronous linkage between the main shaft 110 and the output shaft 120.

[0051] In one possible implementation, an auxiliary switch 500 is also included; the auxiliary switch 500 is fixedly disposed on one side of the mechanism 100, and the trigger end of the auxiliary switch 500 is connected to the output shaft 120 via a connecting rod 510. It should be noted that one end of the connecting rod 510 is hinged to the output shaft 120, and the other end of the connecting rod 510 away from the output shaft 120 is hinged to the trigger end of the auxiliary switch 500. When the output shaft 120 rotates and drives the DSE mechanism to perform opening and closing operations, the trigger end of the auxiliary switch 500 will be displaced accordingly. This allows the auxiliary switch 500 to monitor the movement state of the output shaft 120 in real time, thereby reflecting the opening and closing status of the DSE mechanism. The auxiliary switch 500 generates an electrical signal by switching the normally open and normally closed contacts, and uploads the status information of the DSE mechanism to the remote terminal in the form of an electrical signal, providing accurate equipment status data for remote monitoring. By setting up the auxiliary switch 500, which is connected to the output shaft 120 through mechanical transmission to obtain status information, and its combination detection method with the magnetic attachment and sensor module is independent of each other. This dual-confirmation mechanism from different sources can increase the reliability and accuracy of the system and avoid erroneous operation or false status alarms caused by failure or misjudgment due to a single detection method.

[0052] In one possible implementation, a positioning pin 520 is also included; one end of the main shaft 110 opposite to the cam 410 is disposed through the lower plate 102 of the movement 100, and the positioning pin 520 is fixedly disposed on the main shaft 110 and located at the end of the main shaft 110 opposite to the cam 410. It should be noted that the main body of the positioning pin 520 has a rod-shaped structure. The positioning pin 520 is fixedly disposed at one end of the main shaft 110 that passes through the lower plate 102 of the movement 100, and the positioning pin 520 is disposed through the main shaft 110. The length direction of the positioning pin 520 is perpendicular to the length direction of the main shaft 110. The positioning pin 520 is used to restrict the axial movement of the main shaft 110, ensuring that the position of the main shaft 110 within the movement 100 is fixed and preventing the main shaft 110 from falling out of the movement 100.
