Description

Technical Field

[0001] This utility model relates to the field of switchgear, and in particular to an operating device for a rotary disconnect circuit breaker. Background Technology

[0002] In power systems, rotary vacuum circuit breakers are important power distribution equipment, especially suitable for industrial and mining enterprises, substations, and power plants. These circuit breakers not only possess the functions of a circuit breaker but also function as a disconnecting switch, thus achieving functional integration and simplified operation. However, the design and application of rotary vacuum circuit breakers present a series of technical challenges in the configuration and installation of the operating device.

[0003] The operating mechanism of a rotary vacuum circuit breaker needs to meet specific operational and safety requirements. On the one hand, the operating mechanism needs to be able to drive the circuit breaker to perform opening and closing operations to ensure the stable operation of the power system; on the other hand, because the movement of the isolating contacts needs to be observed from below to ensure operational safety and reliability, the distance from the rotation center to the mounting surface cannot be too large. This requirement limits the design and installation of the operating mechanism, resulting in most traditional operating mechanisms having a relatively large output center, which cannot meet the safety requirements of rotary vacuum circuit breakers.

[0004] Specifically, traditional operating devices typically have a large output center, which results in an excessive distance between the rotation center and the mounting surface when applied to rotary vacuum circuit breakers. This affects the observation of the movement of the isolating contacts. This design not only increases the difficulty of operation but may also reduce equipment safety. For example, during operation, if the movement of the isolating contacts cannot be clearly observed, the operator may be unable to accurately judge the status of the circuit breaker, thus increasing the risk of misoperation. Utility Model Content

[0005] The purpose of this utility model is to solve the above-mentioned technical problems and provide a longitudinal rotating isolating circuit breaker operating device. This application aims to optimize the spatial structure of the longitudinal rotating isolating circuit breaker operating device to facilitate the operator's observation of the movement of the isolating contacts of the circuit breaker.

[0006] A rotary disconnector operating device includes a mounting housing, a rotating mechanism, an energy storage mechanism, and a direct-acting mechanism. The rotating mechanism includes a rotating output ring and a rotating motor. The direct-acting mechanism includes a direct-acting output shaft. The energy storage mechanism stores energy for the direct-acting mechanism. The rotating output ring is sleeved on the direct-acting output shaft. The mounting housing has an output hole. The rotating output ring and the direct-acting output shaft are located at the output hole and have a coaxial axis. The energy storage mechanism includes an energy storage motor and an energy storage transmission system. The energy storage motor is mounted on the bottom of the mounting housing to the right of the axis, and the energy storage transmission system is connected to the output end of the energy storage motor. The direct-acting mechanism is mounted on the mounting housing above the energy storage mechanism. The rotating mechanism is mounted on the mounting housing above the direct-acting mechanism, and the rotating motor is mounted on the mounting housing to the right of the axis.

[0007] According to the operating device of the longitudinal rotating isolating circuit breaker of this application, through spatial layout design, the energy storage motor is designed on the right side and combined with the energy storage transmission system, which shortens the height dimension of the existing operating device. This structure is more suitable for longitudinal rotating isolating circuit breakers and solves the problem of the height limitation of the axis. By arranging the rotating mechanism behind and above the direct-acting mechanism and the rotating motor on the right side, the rotating mechanism and the direct-acting mechanism are closely integrated, resulting in a smaller longitudinal dimension and solving the problem of the longitudinal dimension limitation when the rotating mechanism and the direct-acting mechanism are combined. Furthermore, due to the compact spatial layout adopted in this application, the space utilization rate of the operating device in the length, width and height directions is higher, and the space occupied by the internal mechanism of the operating device is smaller. This allows the operating devices of various models of isolating circuit breakers to be compatible with this solution through the assembly rack, thereby improving product standardization, reducing production preparation and inventory, and solving the problem of the universality of the operating mechanism of longitudinal rotating isolating circuit breakers.

[0008] Furthermore, the rotating mechanism also includes a lead screw and a sliding block. The output end of the rotary motor is connected to the lead screw via a transmission. The sliding block moves along the lead screw as it rotates. A transmission fork extends from the rotating output ring along the movement trajectory of the sliding block. The existence of this movement trajectory allows the sliding block to engage with the transmission fork, thereby driving the rotating output ring to rotate. Through the cooperation of the sliding block and the transmission fork, the linear motion of the lead screw is converted into the rotational motion of the rotating output ring, enabling the operating device to generate a rotational output, thus realizing the isolation function of the circuit breaker.

[0009] Furthermore, the output end of the rotary motor extends from the right side of the mounting housing, and the lead screw also extends from the right side of the mounting housing. The output end is connected to the lead screw via a gear train. This fully utilizes the side space of the mounting housing, making the structure more compact.

[0010] Furthermore, the rotating mechanism also includes a guide rod, which guides the sliding block along the movement trajectory of the lead screw.

[0011] Furthermore, the direct-acting mechanism includes a closing / opening transmission system and an opening spring. One end of the closing / opening transmission system is connected to the energy storage mechanism, and the other end is connected to the direct-acting output shaft. The closing / opening transmission system includes a transmission main shaft, and the opening spring is mounted on the transmission main shaft.

[0012] Furthermore, the mounting housing is provided with a limiting groove, the extension direction of which is parallel to the direction of the axis. Under the limitation of the limiting groove, the closing and opening transmission system pushes the direct-acting output shaft to move along the direction of the axis. Through the limitation of the limiting groove, the direct-acting output shaft can output linear motion under the transmission of the closing and opening transmission system, thereby enabling the circuit breaker to perform the functions of closing and opening.

[0013] Furthermore, the end of the direct-acting output shaft is provided with a connecting shaft inside the mounting housing. Both ends of the connecting shaft are provided with limiting grooves, and both ends of the connecting shaft extend into the limiting grooves. The closing / opening transmission system is connected to the connecting shaft. The connecting shaft facilitates the connection between the closing / opening transmission system and the direct-acting output shaft, and also facilitates matching for limiting.

[0014] Furthermore, the energy storage mechanism also includes an energy storage spring, which is installed at the bottom of the mounting housing below the axis. The energy storage motor is connected to the energy storage spring via an energy storage transmission system. The energy storage spring is installed on the mounting housing to the left of the axis and is used to store energy for the closing action of the direct-acting mechanism. This ensures that the energy storage mechanism does not interfere with the installation of the direct-acting mechanism above.

[0015] Furthermore, the energy storage transmission system is a gear transmission system.

[0016] Furthermore, it also includes a mounting bracket, on which the mounting housing and the mounting bracket are respectively provided with engagement mounting holes. The mounting bracket is installed on one side of the output hole of the mounting housing by bolts engaging with the engagement mounting holes. The mounting bracket is used to install the isolating circuit breaker, so that the isolating circuit breaker is connected to the rotary output ring and the direct-acting output shaft.

[0023] The present invention relates to a longitudinal rotary isolating circuit breaker operating device, which is described in conjunction with the accompanying drawings.

[0024] like Figures 1 to 6 The illustrated operating device for a rotary disconnector includes a mounting housing 1, a rotating mechanism 2, an energy storage mechanism 3, and a direct-acting mechanism 4. The rotating mechanism 2 includes a rotating output ring 26 and a rotating motor 21. The direct-acting mechanism 4 includes a direct-acting output shaft 45. The energy storage mechanism 3 stores energy for the direct-acting mechanism 4. The rotating output ring 26 is sleeved on the direct-acting output shaft 45. Figure 2 As shown, the mounting housing 1 has an output hole 11. The mounting housing 1 includes two intermediate mounting partitions 13 on both sides of the output hole 11 and two outer mounting partitions 14 on the outer sides of the two intermediate mounting partitions 13. The rotary output ring 26 and the direct-acting output shaft 45 are located at the output hole 11 and have a coaxial axis. The energy storage mechanism 3 includes an energy storage motor 31 and an energy storage transmission system 32. The energy storage motor 31 is installed at the bottom of the mounting housing 1 on the right side of the axis. Figure 1 As shown, the energy storage motor 31 is installed between the middle mounting plate 13 and the outer mounting plate 14 on the right side. The energy storage transmission system 32 is connected to the output end of the energy storage motor 31. The energy storage transmission system 32 is installed between the two middle mounting plates 13. By designing the energy storage motor 31 to the right side and combining it with the energy storage transmission system 32, the height dimension of the existing operating device is shortened. This structure is more suitable for use in longitudinal rotary circuit breakers, solving the problem of the height limitation of the axis. The direct-acting mechanism 4 is installed on the mounting housing 1 above the energy storage mechanism 3. The rotating mechanism 2 is installed on the mounting housing 1 above the direct-acting mechanism 4. The rotating motor 21 is installed on the mounting housing 1 on the right side of the axis. Figure 1 As shown, the rotary motor 21 is installed between the middle mounting partition 13 and the outer mounting partition 14 on the right side. By arranging the rotary mechanism 2 above and behind the linear mechanism 4 and the rotary motor 21 on the right side, the rotary mechanism 2 and the linear mechanism 4 are tightly integrated, resulting in a smaller longitudinal dimension and solving the problem of limited longitudinal dimension when the rotary mechanism 2 and the linear mechanism 4 are combined.

[0025] Furthermore, due to the compact spatial layout adopted in this application, the space utilization rate of the operating device in the length, width and height directions is higher, and the space occupied by the internal mechanism of the operating device is smaller. This allows the operating devices of various models of disconnect circuit breakers to be compatible with this solution through the assembly rack, thereby improving product standardization, reducing production preparation and inventory, and solving the problem of universality of the operating mechanism of longitudinal rotary disconnect circuit breakers.

[0026] like Figure 3 As shown, the rotating mechanism 2 also includes a lead screw 23, a guide rod 25, and a sliding block 24. The lead screw 23 is rotatably mounted on the mounting housing 1 via a mounting component. The guide rod 25 is installed parallel to the lead screw 23. In this application, the guide rod 25 and the lead screw 23 are mounted using the same mounting component. The output end of the rotary motor 21 is connected to the lead screw 23 for transmission, enabling the lead screw 23 to rotate. The sliding block 24 moves along the lead screw 23 as the lead screw 23 rotates. The guide rod 25 guides the sliding block 24 along the movement trajectory of the lead screw 23. The rotating output ring 26 has a transmission fork 261 extending towards the movement trajectory of the sliding block 24. The existence of the movement trajectory causes the sliding block 24 to engage with the transmission fork 261, thereby driving the rotating output ring 26 to rotate. The forward and reverse rotation of the lead screw 23 can drive the sliding block 24 to reciprocate on the lead screw 23. The reciprocating movement of the sliding block 24 can drive the rotating output ring 26 to rotate forward or reverse.

[0027] like Figure 4 As shown, the output end of the rotary motor 21 extends out from the right side of the mounting housing 1, and the lead screw 23 also extends out from the right side of the mounting housing 1, that is, it extends out from the outer side of the right side mounting partition 14, so as not to occupy the internal space of the mounting housing 1. The output end is connected to the lead screw 23 through the gear train 22.

[0028] like Figure 1 and Figure 5 As shown, the direct-acting mechanism 4 includes a closing and opening transmission system 41 and an opening spring 42. One end of the closing and opening transmission system 41 is connected to the energy storage mechanism 3, and the other end is connected to the direct-acting output shaft 45. The closing and opening transmission system 41 includes a transmission main shaft 43, and the opening spring 42 is mounted on the transmission main shaft 43.

[0029] like Figure 5 As shown, the mounting housing 1 is provided with a limiting groove 12, such as Figure 2As shown, the limiting groove 12 is installed on the two intermediate partition plates 13. The extension direction of the limiting groove 12 is parallel to the direction of the axis. The closing and opening transmission system 41 pushes the direct-acting output shaft 45 to move along the axis direction under the limiting of the limiting groove 12. Through the limiting of the limiting groove 12, the direct-acting output shaft 45 can output linear motion under the transmission of the closing and opening transmission system 41, thereby enabling the circuit breaker to realize the functions of closing and opening.

[0030] like Figure 5 As shown, the end of the direct-acting output shaft 45 is provided with a connecting shaft 44 inside the mounting housing 1. Both ends of the connecting shaft 44 are provided with the limiting groove 12, and both ends of the connecting shaft 44 extend into the limiting groove 12. The closing and opening transmission system 41 is connected to the connecting shaft 44. The connecting shaft 44 can facilitate the connection between the closing and opening transmission system 41 and the direct-acting output shaft 45 and facilitate the cooperation for limiting.

[0031] like Figure 1 As shown, the energy storage mechanism 3 also includes an energy storage spring 33, which is installed at the bottom of the mounting housing 1 below the axis. The energy storage motor 31 is connected to the energy storage spring 33 via the energy storage transmission system 32. The energy storage spring 33 is installed on the mounting housing 1 on the left side of the axis. The energy storage spring 33 is used to store energy for the closing action of the direct-acting mechanism 4, so that the energy storage mechanism 3 does not affect the installation of the direct-acting mechanism 4 above.

[0032] Preferably, the energy storage transmission system 32 is a gear transmission system.

[0033] like Figure 4 and Figure 6 As shown, it also includes a mounting bracket 5. The mounting housing 1 and the mounting bracket 5 are respectively provided with engagement mounting holes (15, 51). The mounting bracket 5 is installed on one side of the output hole 11 of the mounting housing 1 by bolts engaging with the engagement mounting holes (15, 51). The mounting bracket 5 is used to install the isolating circuit breaker, so that the isolating circuit breaker is connected to the rotary output ring 26 and the direct-acting output shaft 45.

Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
