Problems solved by technology
For example, the operating device of Patent Document 1 has the following problems: a worm gear is used in the reduction mechanism, and the rotating shafts are perpendicular to each other, which not only has poor transmission efficiency, but also complicates the structure
In addition, in the operating device of Patent Document 2, there is a problem that the one-way clutch is provided on the side of the switch main body. This structure is not suitable for the case where high-speed operation is required on both the open side and the close side, and the structure becomes complicated.
Furthermore, in the operating device of Patent Document 3, the link structure used to reduce the operating force used is directly connected to the switch main body through rollers. These are to re-evaluate the linkage structure used to reduce the operating force used, which is not suitable for standardization

The invention relates to an opening-closing operating device which can simplify a structure and can obtain relatively big action force during the later half period of a closing action. An output transmission mechanism (40) comprises: a transmission lever (44) rotating around an output shaft (45) and transmitting release force to the output shaft (45); a connecting rod (43) with one end thereof connected at the front end of the transmission lever (44) by a second connecting peg (47); and a release lever (42) supported by a main shaft (35) mounted at a position different from the position of the output shaft (45), connected with the other end of the connecting rod (43) by a first connecting peg (46), and rotating by means of release force of an energy-stored spring (53). With the action of an opening-closing main body (80) from an opening state to a closing state, the mutually bent transmission lever (44), connecting rod (43) and release lever (42) are correspondingly extended when the opening-closing main body (80) is in the opening state so as to make the main shaft (35), the first connecting peg (46) and the second connecting peg (47) arranged in an approximate straight line.
Description
technical field [0001] The present invention relates to an operating device of a switch used in a substation, a power plant, etc., and in particular to an operating device of a spring-operated switch. The released force of the stored energy spring causes the contacts of the switch to switch at high speed. Background technique [0002] Many proposals have been made in the past regarding an operating device that uses the release force of such an energy storage spring to switch contacts of a switch at high speed. For example, it has been proposed to provide the spring as a coil spring and connect two or more of the coil springs to the same spring shaft to increase the output without causing damage (for example, refer to Patent Document 1). [0003] In addition, in a switch with a manual operation shaft that can be manually operated, a proposal has been proposed that when high-speed operation is required only for one of the open side and the close side, the rotating main shaft ...
