1results about How to "Short breaking time" patented technology

This utility model relates to a double-acting arc-extinguishing chamber based on ball screw transmission, including a housing, a moving contact and a stationary contact disposed within the housing, a ball screw rotatably disposed within the housing, a first fixed block fixedly connected to the moving contact, and a second fixed block fixedly connected to the stationary contact. One end of the ball screw is connected to a drive device. The ball screw has a first threaded section and a second threaded section with opposite directions of rotation. The first fixed block is threadedly connected to the first threaded section, and the second fixed block is threadedly connected to the second threaded section. A first guide rail is fixedly disposed on the housing, slidingly engaging with the first fixed block, and a second guide rail is slidably engaged with the second fixed block. This utility model, through ball screw transmission, converts rotational motion into linear motion of the first and second fixed blocks, realizing the opposite or opposite movements of the moving and stationary contacts, improving the closing and opening speeds of the arc-extinguishing chamber, shortening the breaking time, and effectively improving the breaking capacity of the circuit breaker.
