| 摘要 | PURPOSE: To obtain a driving device with a mechanical trip release system at a low cost by providing a trip link rotatably supported by a pin slid interlockingly with a trip lever connected to a pin via a long hole at one end and driven by a trip device at the other end. CONSTITUTION: Connecting rods 31, 32 are connected by a connecting pin 35, two links 31, 32 are bent only to one side while the connecting pin 35 serves as a fulcrum across the dead center, and a return spring 36 exciting the links 31, 32 in the extending direction is provided. A trip link 37 is provided to act on the links 31, 32, and it is rotatably supported by a slide pin 39 provided to be slid interlockingly with a trip lever 44 connected to the connecting pin 35 via a long hole 38 at one end and driven and rotated by a trip device 46 via a trip command at the other end. A trip release system can be easily added, and a circuit breaker with the mechanical trip release system having high reliability is obtained at a low cost. COPYRIGHT: (C)1992,JPO&Japio |
