Description

Technical Field

[0001] This utility model relates to the field of operating mechanisms, and more particularly to a hydraulic disc spring operating mechanism for GIS. Background Technology

[0002] The hydraulic disc spring operating mechanism for GIS is the core actuator for driving the opening and closing of circuit breakers in high-voltage gas-insulated switchgear (GIS), primarily used for rapid control and protection of high-voltage circuits in power systems. Its core function is to provide active driving force through the hydraulic system to push the circuit breaker contacts to complete the opening (interrupting fault current) or closing (connecting the circuit) actions. Simultaneously, it utilizes a pre-compressed disc spring assembly as a backup energy storage unit, releasing elastic potential energy to achieve emergency opening in the event of hydraulic failure, ensuring operational reliability under extreme conditions. Combining the high power density of hydraulic transmission with the mechanical redundancy of disc springs, the mechanism can respond to commands within 10-30 milliseconds, meeting the stringent requirements of high-voltage circuit breakers for operating speed, breaking capacity (e.g., short-circuit current above 63kA), and resistance to arc erosion. It is particularly suitable for ultra-high-voltage power transmission, urban underground substations, and new energy grid connection scenarios.

[0003] However, there are certain defects in the operating mechanism in the existing technology. The disc spring mechanism mainly undertakes the core functions of energy storage, power transmission and emergency backup in high-voltage power equipment. During long-term operation, the disc spring is susceptible to fatigue damage and stress relaxation, which leads to a decrease in energy storage capacity and thus affects the response speed and reliability of the mechanism. If the disc spring is too loose, the crank arm transmission will be insensitive, causing the entire mechanism to fail to operate. In severe cases, it may cause the circuit breaker to fail to trip in time, resulting in power system failure.

[0004] Therefore, a hydraulic disc spring operating mechanism for GIS is proposed here to solve the above-mentioned problems. Utility Model Content

[0005] In order to overcome the shortcomings of existing technologies where disc springs are susceptible to fatigue damage and stress relaxation during long-term operation, resulting in a decrease in energy storage capacity, this utility model provides a hydraulic disc spring operating mechanism for GIS.

[0006] This utility model is achieved using the following technical solution:

An a-axis, b-axis, c-axis, c1-axis, a central shaft, and a rotation shaft are respectively installed between the a-side plate and the b-side plate. The a-axis has an a-tooth, and the b-axis has a b-tooth that meshes with the a-axis. One end of the b-axis has a first crank arm connected to a first disc spring. The end of the first disc spring has a transmission arm connected to one end of the c-axis. The c-axis has a c-tooth, and the central shaft has a central rotation tooth that meshes with the c-tooth. The c1-axis has a c1-tooth that meshes with the central rotation tooth. One end of the c1-axis has a second crank arm connected to a second disc spring. The end of the second disc spring is connected to the rotation shaft.

The first disc spring 31 and the second disc spring 61 do not interfere with each other during compression and extension, ensuring efficient operation between the gears.

[0043] The principle of this utility model is as follows: the device is fixed to the equipment to be connected through the reserved hole 81, and the energy storage box 1 is connected to the external electrical equipment. When it is necessary to close or open the circuit, the energy in the energy storage box 1 is transmitted to the a shaft 2 through the transmission shaft 11, which in turn drives the b shaft 23 to rotate. At the same time as the b shaft 23 rotates, the first crank arm 3 drives the first disc spring 31 to compress and extend. The transmission arm 32 then drives the c shaft 4 to rotate. The c tooth 41 on the c shaft 4 meshes with the intermediate rotation tooth 51 on the intermediate rotation shaft 5. The intermediate rotation tooth 51 then drives the c tooth 43 on the c1 shaft 42 to rotate.
