Description

Technical Field

[0001] The invention relates to the field of switch equipment, in particular to an operating device for a longitudinally rotating isolating circuit breaker. Background Art

[0002] In the power system, the longitudinal-rotation isolating vacuum circuit breaker is an important power distribution equipment, especially suitable for industrial and mining enterprises, substations and power plants. This type of circuit breaker not only has the function of a circuit breaker, but also has the function of an isolating switch, thus achieving the combination of functions and the simplification of operation. However, in the design and application of the longitudinal-rotation isolating vacuum circuit breaker, the configuration and installation of the operating device face a series of technical challenges.

[0003] The operating device of the longitudinal-rotation isolation vacuum circuit breaker needs to meet specific operation and safety requirements. On the one hand, the operating device needs to be able to drive the circuit breaker to open and close to ensure the stable operation of the power system; on the other hand, since the movement of the isolation contact needs to be observed from the front and bottom to ensure the safety and reliability of the operation, the distance from the rotation center to the mounting surface cannot be too large. This requirement limits the design and installation of the operating device, making the output center of most traditional operating devices larger and unable to meet the safety requirements of the longitudinal-rotation isolation vacuum circuit breaker.

[0004] Specifically, traditional operating devices usually have a large output center, which results in a large distance from the rotation center to the mounting surface when applied to longitudinally rotating isolating vacuum circuit breakers, thus affecting the observation of the movement of the isolating contacts. This design not only increases the difficulty of operation, but may also reduce the safety of the equipment. For example, during operation, if the movement of the isolating contacts cannot be clearly observed, the operator may not be able to accurately judge the status of the circuit breaker, thereby increasing the risk of misoperation.

[0023] A longitudinal rotation isolating circuit breaker operating device of the present invention is described in conjunction with the accompanying drawings.

[0024] like Figures 1 to 6 The longitudinal rotation disconnecting circuit breaker operating device shown in the figure comprises a mounting housing 1, a rotating mechanism 2, an energy storage mechanism 3 and a direct-acting mechanism 4, wherein the rotating mechanism 2 comprises a rotating output ring 26 and a rotating motor 21, the direct-acting mechanism 4 comprises a direct-acting output shaft 45, the energy storage mechanism 3 is used to store energy for the direct-acting mechanism 4, and the rotating output ring 26 is sleeved on the direct-acting output shaft 45, as shown in FIG. Figure 2 As shown, the mounting housing 1 is provided with an output hole 11, and the mounting housing 1 includes two middle mounting baffles 13 on both sides of the output hole 11 and two outer mounting baffles 14 outside the two middle mounting baffles 13. The rotating output ring 26 and the direct-acting output shaft 45 are arranged 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 partition 13 and the outer mounting partition 14 on the right side, the energy storage transmission system 32 is transmission-connected with the output end of the energy storage motor 31, and the energy storage transmission system 32 is installed between the two middle mounting partitions 13. The energy storage motor 31 is designed to the right side and is combined with the energy storage transmission system 32. Now, for the existing operating device, its height dimension is shortened. This structure is more suitable for longitudinal rotation isolating circuit breakers, which solves the height limitation problem of the axis centerline; the direct-acting mechanism 4 is installed on the mounting shell 1 above the energy storage mechanism 3, the rotating mechanism 2 is installed on the mounting shell 1 above the direct-acting mechanism 4, and the rotating motor 21 is installed on the mounting shell 1 on the right side of the axis centerline, as shown in FIG. Figure 1 As shown, the rotating motor 21 is installed between the middle mounting partition 13 and the outer mounting partition 14 on the right side. By arranging the rotating mechanism 2 above and behind the direct-acting mechanism 4 and the rotating motor 21 on the right side, the rotating mechanism 2 is tightly combined with the direct-acting mechanism 4 to obtain a smaller longitudinal size, thereby solving the problem of limited longitudinal size of the combination of the rotating mechanism 2 and the direct-acting mechanism 4.

[0025] Furthermore, due to the compact spatial layout adopted in the present application, the space utilization rate of the operating device in the three directions of length, width and height is higher, and the space occupied by the mechanism inside the operating device is smaller, so that the operating devices of various types of isolating circuit breakers can be compatible with this solution through the assembly rack, so that product standardization is improved, production preparation and inventory are reduced, and the problem of universalization of the operating mechanism of the longitudinal rotation isolating circuit breaker is solved.

[0026] like Figure 3 As shown, the rotating mechanism 2 also includes a screw rod 23, a guide rod 25, and a sliding block 24.

In the present application, the guide rod 25 and the screw rod 23 are mounted using the same mounting piece. The output end of the rotating motor 21 is transmission-connected with the screw rod 23 so that the screw rod 23 can rotate. The sliding block 24 moves along the screw rod 23 as the screw rod 23 rotates. The guide rod 25 guides the sliding block 24 along the motion trajectory of the screw rod 23. A transmission fork 261 extends from the rotating output ring 26 toward the motion trajectory of the sliding block 24. The existence of the motion trajectory causes the sliding block 24 to abut against the transmission fork 261, thereby driving the rotating output ring 26 to rotate. The forward and reverse rotation of the screw rod 23 can drive the sliding block 24 to reciprocate on the screw rod 23. The reciprocating movement of the sliding block 24 can drive the rotating output ring 26 to rotate forward or reverse.

The closing and opening transmission system 41 includes a transmission main shaft 43, and the opening spring 42 is installed on the transmission main shaft 43.

[0029] like Figure 5 As shown, the mounting housing 1 is provided with a limiting groove 12. Figure 2As shown, the limit groove 12 is arranged on two middle mounting partitions 13, and the extension direction of the limit groove 12 is parallel to the direction of the axis center line. The closing and opening transmission system 41 pushes the direct-acting output shaft 45 to move along the axis center line under the limitation of the limit groove 12. Through the limitation of the limit groove 12, the direct-acting output shaft 45 can output linear motion under the transmission of the closing and opening transmission system 41, so that the circuit breaker can realize the closing and opening functions.

[0030] like Figure 5 As shown, a connecting shaft 44 is provided at the end of the direct-acting output shaft 45 in the mounting shell 1, and both ends of the connecting shaft 44 are provided with the limiting grooves 12, and both ends of the connecting shaft 44 extend into the limiting grooves 12, and the closing and opening transmission system 41 is connected to the connecting shaft 44, and 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, and the energy storage spring 33 is installed at the bottom of the mounting shell 1 below the axis. The energy storage motor 31 is connected to the energy storage spring 33 through an energy storage transmission system 32. The energy storage spring 33 is installed on the mounting shell 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 upper direct-acting mechanism 4.

[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 frame 5, and the mounting housing 1 and the mounting frame 5 are correspondingly provided with engaging mounting holes (15, 51), and the mounting frame 5 is mounted on one side of the output hole 11 of the mounting housing 1 by bolts cooperating with the engaging mounting holes (15, 51).
