CTY type spring energy storage hydraulic operating mechanismDetailed product description：

In the field of high-voltage SF6 switches, the hydraulic operating mechanism is generally responsible for the switch operation task. Most of these mechanisms use nitrogen as the energy storage medium, and their working pressure varies with the ambient temperature, and there is a problem of nitrogen leakage. In terms of structure, each hydraulic component is separated and needs to be connected by pipelines. As a result, there are too many sealing links and serious external oil leakage problems, which affect the reliability of high-pressure switch operation. To this end, the separated hydraulic component system has been replaced with an integrated module combination system, reducing the sealing link and replacing the nitrogen energy storage medium with a disc spring. This has fundamentally improved and enhanced the leak prevention and pressure characteristics of nitrogen and oil leakage, and is a major breakthrough for similar foreign products. This mechanism not only eliminates and improves the serious defects of old hydraulic mechanisms, but also provides convenience for various high-pressure switch configurations with newly added opening and closing operation functions and speed adjustable functions. It has been recognized by the Chinese market and even the world market. However, the control of the HMB-4 mechanism is still based on the principle of multi-stage control valves, and practical experience has shown that there are still deficiencies that affect its reliability. Wenzhou Yikun Electric Co., Ltd. has introduced and digested advanced foreign technology, and independently developed the CTY-4 spring energy storage hydraulic operating mechanism, which is superior to the HMB-4 mechanism in terms of design principles and structure. With highly simplified technology, it has achieved excellent and reliable performance.
