Abstract

The invention relates to a cam operating mechanism with self-locking stations and an operating method thereof, which are designed to solve the technical problem of poor structure design of the existing similar products. The cam operating mechanism mainly uses the movement principle of a disk cam to achieve the purpose that a crank arm of an output shaft rotates for a certain angle during outward output, i.e. the disk cam is provided with an ear-shaped groove meeting the requirement of the output angle, and the ear-shaped groove comprises a two-station conversion spiral groove and a three-station localization circular groove. When a disk cam shaft rotates continuously clockwise (or counterclockwise), the disk cam shaft drives a roller bearing of the crank arm of the output shaft to rotate together to realize the station conversion of the output shaft. The cam operating mechanism is mainly used on an EDS (earthing disconnecting switch), a DS (disconnecting switch) or an ES (earthing switch) of a power system, and has the characteristics that the localization is accurate, no rebound exists, the defects of starting with load and power failure with inertial rotation of a motor are eliminated, and the like.

Description

technical field [0001] The invention relates to an isolating switch of a high-voltage switching device, and relates to a position self-locking cam operating mechanism and an operating method thereof. Background technique [0002] The isolating switch is the most widely used electrical appliance in high-voltage switching appliances. It plays an isolation role in the circuit and is an important switching device for the power system to realize switching and switching circuits. Its working principle and structure are relatively simple, but due to the large amount of use and high reliability requirements, it has a great impact on the design, establishment and safe operation of substations and power plants. At present, there are two types of problems. One is that the isolation position cannot achieve accurate mechanical limit, which is easy to cause position misalignment, resulting in unpredictable changes in the travel distance from the isolation position to the closing or ground...
