[CN 201720652501.7] Disc spring support flange for hydraulic mechanism of UHV circuit breaker


[CN 201720652501.7] Title of disc spring support flange for UHV circuit breaker hydraulic mechanism: Application number of disc spring support flange for UHV circuit breaker hydraulic mechanism: CN 201720652501.7 Applicant: Shandong Taikai High Voltage Switch Co., Ltd. Application Date: 2017-6-7 Patent Type: Utility Model The utility model relates to a disc spring support flange for UHV circuit breaker hydraulic mechanism, and the disc spring support flange is symmetrically arranged on both sides of the main cylinder body, it is connected with the main cylinder body by multiple bolts. The small end of the disc spring support flange is threaded and connected with the spring support sleeve. The disc spring is sleeved on the spring support sleeve, and the spring lower tray and the support half ring are used for limiting. The disc spring supports the flange plate with multi-step structure, and the step transition adopts conical fillet transition, which optimizes the mechanical characteristics, avoids stress concentration and has a reasonable structure. The flange plate is provided with a positioning stop to ensure that the flange plate is aligned with the main cylinder body, prevent the flange plate from moving backward under force, and eliminate the lateral shearing force of the bolt. The central part of the flange plate is a large through hole. Without changing the mechanical characteristics of the flange plate, effectively reduce the weight of the product, while also improving the stress state of the product. The structure of this flange makes the high compression force of the disc spring act on the disc spring support flange, which not only does not require higher requirements on the main cylinder, but also has higher reliability.
