Description

Technical Field

[0001] This application relates to the field of power equipment drive technology, and in particular to an open disconnect switch drive mechanism. Background Technology

[0002] Disconnect switches, as critical high-voltage electrical equipment in power systems, are primarily used to isolate power sources and ensure maintenance safety during equipment upkeep, as well as to switch circuits to change system operating modes. Their core function relies on reliable opening and closing operations, and the performance of the drive mechanism directly affects the accuracy, stability, and service life of the disconnect switch. With the expansion of power grids and the increasing demand for intelligent systems, the technical requirements for the drive mechanisms of open-type disconnect switches are becoming increasingly stringent.

[0003] Existing technologies suffer from several drawbacks: low control precision; slow response speed and large torque fluctuations in asynchronous motors make precise adjustment of opening and closing speeds difficult; reliance on mechanical limit feedback makes real-time monitoring of the action process (such as jamming or overtravel) impossible, leading to contact erosion or isolation failure due to overshoot or under-travel. Poor environmental adaptability: open disconnect switches are mostly deployed outdoors, requiring tolerance to harsh environments such as high temperatures, high humidity, salt spray, and dust. In traditional mechanisms, gearboxes are prone to jamming due to aging and failure of lubricating grease, contactor contacts are susceptible to dust contamination and adhesion, and motor windings are prone to short circuits due to moisture, resulting in a high failure rate. High maintenance costs: mechanical transmission chains (such as gears and connecting rods) suffer severe wear from long-term operation, requiring regular manual calibration; electronic components have weak anti-interference capabilities, making them prone to malfunctions and other technical problems due to complex electromagnetic environments (such as corona discharge from nearby high-voltage equipment).

[0007] In one feasible implementation, the housing assembly further includes: A flange edge is provided along the circumference of the inner wall of the housing; A sealing strip is disposed inside the flange edge.

[0008] In one feasible implementation, it further includes: A fixing component is disposed inside the housing, and the speed reducer is fixedly connected to the housing through the fixing component.

[0009] In one feasible implementation, the fixing component includes: Mounting flange, which is disposed on the side surface of the reducer; A hollow bolt, one end of which passes through the mounting flange, and the other end of the hollow nut having a wing plate, and a hexagonal hole being formed at the center of the hollow bolt; A fastening bolt passes through the hexagonal hole of the hollow bolt and through the mounting hole of the housing, and is connected to the external platform.

[0010] In one feasible implementation, it further includes: A device mounting plate, wherein the device mounting plate has an upper mounting plate and a lower mounting plate; The upper mounting plate is equipped with a circuit breaker, a trip switch, a closing switch, an emergency stop switch, and a rotary switch; The lower mounting plate is provided with double-layer wiring terminals, which are electrically connected to circuit breakers, trip switches, closing switches, emergency stop switches, and rotary switches.

[0011] In one feasible implementation, the servo driver is electrically connected to a double-layer terminal block; Indicator lights are disposed on the surface of the servo driver and have indications for power, operation, zero position, and alarm.

[0012] In one feasible implementation, it further includes: A hand-cranked assembly is connected to the reducer and is used to manually drive the reducer.

[0013] In one feasible implementation, the hand-cranked assembly includes: A hand-cranked interface is located on one side of the reducer; A hand crank linkage, one end of which is connected to the hand crank interface, and the other end of which extends out of the housing assembly; An electric wrench, wherein the electric wrench is connected to one end of the hand crank that extends out of the housing assembly.

[0014] In one feasible implementation, it further includes: A temperature sensor, which is electrically connected to the heater; A humidity sensor, which is electrically connected to the dehumidifier.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: The open disconnect switch drive mechanism provided in this application includes a servo motor, a housing assembly, a reducer, a heater, a dehumidifier, a servo driver, and an auxiliary switch group.

[0018] This technical solution uses a speed reducer, whose input end is connected to the output end of the servo motor, and finally outputs force to the disconnect switch through the output port of the speed reducer. This achieves a servo control strategy for the large operating torque of the disconnect switch, which can reach several thousand Newton-meters. This reduces the possibility of motor overheating or damage due to overload and effectively improves the quality of the equipment.

[0019] This technical solution incorporates a servo driver and an auxiliary switch group. The servo driver receives feedback from its built-in encoder to determine the motor's rotation angle. When the motor reaches the target angle, it receives a signal. Simultaneously, the auxiliary switch group, located on one side of the reducer, comprises multiple pairs of switches. During reducer rotation, each pair of auxiliary switches independently outputs open and close signals, allowing for electromechanical verification of the reducer's rotation angle. This solution, through the cooperation of the servo driver and auxiliary switch group, cross-verifies signal accuracy, effectively improving equipment reliability. Even minor errors in the servo controller or a fault in one set of auxiliary switches prevent misjudgments and reduce false alarms. Significant inconsistencies between the signals from the servo controller and the auxiliary switch group indicate potential jamming, slippage, or damage in the servo motor or reducer, enabling timely repairs and enhancing the solution's self-diagnostic capabilities, further improving equipment reliability.

[0022] To better understand the above technical solutions, the technical solutions of the embodiments of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this application and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.

[0023] like Figure 1-7 As shown in the embodiment of this application, an open isolating switch drive mechanism is proposed, comprising: a servo motor 100; a housing assembly 200, wherein the servo motor 100 is disposed inside the housing assembly 200; a reducer 300, wherein the reducer 300 is disposed inside the housing assembly 200, and the output end of the servo motor 100 and the input point of the reducer 300 are rigidly connected; a heater 400, wherein the heater 400 is disposed inside the housing assembly 200; a dehumidifier 500, wherein the dehumidifier 500 is disposed inside the housing assembly 200; a servo driver 600, wherein the servo driver 600 is electrically connected to the servo motor 100; and an auxiliary switch group 110, wherein the auxiliary switch group 110 is disposed at one end of the shaft of the reducer 300, and the auxiliary switch group 110 has a plurality of auxiliary switches.

[0024] The open disconnect switch drive mechanism provided in this application embodiment includes a servo motor 100, a housing assembly 200, a reducer 300, a heater 400, a dehumidifier 500, a servo driver 600, and an auxiliary switch group 110.

[0025] In this technical solution, a servo motor 100 is introduced to replace the asynchronous motor, and its high-precision speed regulation and torque control advantages are utilized to effectively solve the problem of low control accuracy of asynchronous motors.

[0026] The outer casing assembly 200 is equipped with a dehumidifier 500 and a heater 400. When facing harsh environments such as severe cold weather, high humidity, high salt spray, and sandstorms, the internal humidity and temperature can be adjusted through the dehumidifier 500 and the heater 400, which effectively improves the environmental adaptability of this technical solution.

[0027] This technical solution includes a speed reducer 300, whose input end is connected to the output end of the servo motor 100. The speed reducer 300 outputs force to the disconnect switch, thus realizing a servo control strategy for the large operating torque of the disconnect switch, which can reach several thousand Newton-meters. This reduces the possibility of motor overheating or damage due to overload and effectively improves equipment quality.

[0028] This technical solution includes a servo driver 600 and an auxiliary switch group 110. The servo driver 600 can obtain the motor rotation angle through feedback from its built-in encoder. When the motor rotates to the target angle, the servo motor 100 receives a signal. Simultaneously, the auxiliary switch group 110 is located on one side of the reducer 300 and has multiple pairs of auxiliary switches. During the rotation of the reducer 300, each pair of auxiliary switches can independently output open and close signals, thus confirming the rotation angle of the reducer 300 at the electromechanical level. This technical solution, through the cooperation of the servo driver 600 and the auxiliary switch group 110, can cross-confirm the accuracy of the signals, thereby effectively improving the reliability of the equipment. Even if the servo controller has a minor error, or a switch in the auxiliary switch group 110 fails, it can avoid system misjudgment and reduce the probability of false alarms. When the signals fed back by the servo controller and the auxiliary switch group 110 are significantly inconsistent, it can be considered that there is a fault in the servo motor 100 or the reducer 300, such as jamming, slippage, or damage. Personnel can then perform timely repairs, effectively improving the self-diagnosis capability of this technical solution and further enhancing the reliability of the equipment.

[0029] like Figure 3 As shown, the drive mechanism provided by this technical solution allows all components to be removed and maintained through the opening of the housing assembly 200. This makes both controller wiring and device wiring more convenient, and also makes device damage and fault maintenance easier.

[0030] like Figure 1-7As shown, the housing assembly 200 includes: a housing 210 made of stainless steel; a housing cover 220 made of stainless steel, rotatably connected to the housing 210; an output spindle 230 disposed on the side surface of the housing 210, the input end of the output spindle 230 connected to the output end of the reducer 300; a lifting ring 240 disposed on the side surface of the housing 210 and on the same side as the output spindle 230; a manual door lock 250 disposed on the housing cover 220 for locking and unlocking the housing cover 220 and the housing 210; and a nameplate 260 disposed on the housing cover 210. Cover 220; Dehumidification drain pipe 270, which is disposed inside the housing 210, with one end connected to the dehumidifier and the other end connected to the cover 220; Cable lock head 280, which is disposed on the side surface of the housing 210, through which an external cable enters the housing 210, and is disposed on the opposite side of the housing 210; Fixing bolt 290, which is disposed on the housing 210 and on the opposite side of the cover 220; Padlock 211, which is provided with lugs on both the housing 210 and the cover 220, and is used to connect the housing 210 and the cover 220.

[0031] In this technical solution, the outer casing assembly 200 includes a housing 210, a cover 220, an output spindle 230, a lifting ring 240, a hand-tight door lock 250, a nameplate 260, a dehumidification drain pipe 270, a cable lock head 280, a fixing bolt 290, and a padlock 211.

[0032] The output spindle 230 is located on one side of the housing 210. The output end of the output spindle 230 is connected to the reducer 300 inside the housing 210. The output end of the output spindle 230 is used to connect to the external partition switch.

[0033] The lifting ring 240 and the fixing bolt 290 are used to fix the housing 210 to the external mounting platform, thereby improving the stability of this technical solution.

[0034] Padlock 211 is used to protect the equipment when no one is maintaining it, to prevent unauthorized personnel from operating the equipment and causing damage or even accidents. However, padlock 211 cannot achieve a tight closure between housing 210 and cover 220. Therefore, a hand-tight door lock 250 is added so that cover 220 is tightly attached to housing 210 when closed.

[0035] The housing 210 has a cable lock head 280 on its side wall, which is used to clamp and fix the external power and control cables and form an effective seal at the cable entry point to prevent dust and moisture from entering the interior of the housing 210.

[0036] like Figure 1-7 As shown, the housing assembly 200 further includes: a flange edge, which is disposed along the periphery of the inner wall of the housing 210; and a sealing strip, which is disposed inside the flange edge.

[0037] In this technical solution, the housing assembly 200 also includes a flange and a sealing strip. The flange and sealing strip effectively improve the sealing performance of the housing 210 and cover 220 when closed. Combined with the cable locking head 280 mentioned above, the overall sealing capability of the housing assembly 200 reaches IP54 or higher. This effectively protects the internal electronic components of the housing assembly 200 from dust, moisture, water, and even salt spray corrosion, improving the environmental adaptability of this technical solution.

[0038] like Figure 1-7 As shown, it also includes: a fixing component 700, which is disposed inside the housing 210, and the reducer 300 is fixedly connected to the housing 210 through the fixing component 700.

[0039] like Figure 1-7 As shown, the fixing assembly 700 includes: a mounting flange 710 disposed on the side surface of the reducer 300; a hollow bolt 720, one end of which passes through the mounting flange 710, the other end of which has a wing plate, and a hexagonal hole at the center of the hollow bolt 720; and a fastening bolt 730, which passes through the hexagonal hole of the hollow bolt 720 and through the mounting hole of the housing 210, and is connected to the external platform.

[0040] In this technical solution, the reducer 300 is fixed to the housing assembly 200 and the external platform by a fixing component 700. Specifically, mounting flanges 710 are provided on both sides of the reducer 300, and hollow bolts 720 extend into the mounting flanges 710. The lower end of the hollow bolts 720 has threads, and the bottom plate of the housing assembly 200 has threaded mounting holes. The hollow bolts 720 can be screwed into the mounting holes of the housing assembly 200 through the threads at their lower ends, thereby fixing the reducer 300 and the housing assembly 200. The fastening bolts 730 use the hexagonal holes of the hollow bolts 720 as mounting holes, pass through the hollow bolts 720, and extend into the external mounting platform of the housing assembly 200. In this configuration, the weight and vibration of the reducer 300 are mainly borne by the external mounting platform, rather than entirely acting on the housing assembly 200. Therefore, the possibility of deformation of the housing assembly 200 and seal failure is reduced, greatly improving the convenience of equipment maintenance and the reliability of the equipment.

[0041] like Figure 1-7 As shown, it also includes: a device mounting plate 910, which has an upper mounting plate and a lower mounting plate; the upper mounting plate is provided with a circuit breaker 920, a trip switch 930, a closing switch 940, an emergency stop switch 950 and a rotary switch 960; the lower mounting plate is provided with a double-layer terminal block 970, which is electrically connected to the circuit breaker 920, the trip switch 930, the closing switch 940, the emergency stop switch 950 and the rotary switch 960.

[0042] In this technical solution, the drive device also includes a device mounting plate 910, which is divided into two layers. The upper layer is equipped with a circuit breaker 920, a trip switch 930, a closing switch 940, an emergency stop switch 950, and a rotary switch, while the lower layer is equipped with a double-layer terminal block 970. In this configuration, opening the cover 220 allows direct operation of the circuit breaker 920, the trip switch 930, the closing switch 940, the emergency stop switch 950, and the rotary switch, which is more convenient. The double-layer terminal block 970 on the lower layer makes reasonable use of space for cable connection, resulting in a more rational spatial layout.

[0043] like Figure 1-7 As shown, the servo driver 600 is electrically connected to a double-layer terminal block 970; an indicator light is disposed on the surface of the servo driver 600, and the indicator light has indication items for power, operation, zero position and alarm.

[0044] In this technical solution, the servo driver 600 has an indicator light, and the housing assembly 200 has an observation window at the location where the indicator light is located on the servo driver 600. With this setting, the operating status of the drive device can be judged by observing the indicator light of the servo driver 600 through the observation window without opening the housing assembly 200, so that the device can be repaired in time when a fault occurs.

[0045] Understandably, a sealing strip is provided at the observation window of the housing assembly 200, and the servo drive 600 is positioned by abutting against the sealing strip, thereby avoiding damage to the sealing of the housing assembly 200.

[0046] like Figure 1-7 As shown, it also includes: a hand crank assembly 800, which is connected to the reducer 300 and is used to manually drive the reducer 300.

[0047] like Figure 1-7 As shown, the hand-crank assembly 800 includes: a hand-crank interface 810, which is disposed on one side of the reducer 300; a hand-crank connecting rod 820, one end of which is connected to the hand-crank interface 810, and the other end of which extends out of the housing assembly 200; and an electric wrench 830, which is connected to the end of the hand-crank connecting rod 820 that extends out of the housing assembly 200.

[0048] In this technical solution, the drive mechanism also includes a hand crank assembly 800. This configuration ensures that when the equipment malfunctions or loses power, the hand crank linkage 820 and the electric wrench 830 can be inserted into the housing assembly 200 and connected to the hand crank interface 810 to temporarily drive the reducer 300 manually.

[0049] like Figure 1-7 As shown, it also includes: a temperature sensor electrically connected to the heater 400; and a humidity sensor electrically connected to the dehumidifier 500.

[0050] In this technical solution, the drive mechanism also includes a temperature sensor and a humidity sensor. The temperature sensor is connected to the heater 400, and the humidity sensor is connected to the dehumidifier 500. When the temperature sensor and the humidity sensor detect that the ambient temperature reaches the threshold, they can control the heater 400 and the dehumidifier 500 to start working. This technical solution realizes the automatic adaptation of the drive mechanism to the environment, without the need for manual control of the heater 400 and the dehumidifier 500.
