Abstract
The utility model discloses a mechanism for facilitating circuit breaker detection. The mechanism for facilitating circuit breaker detection includes an arc extinguishing chamber; a positioning pin which can move up and down vertically and is located at a movable end of the arc extinguishing chamber is a long pin; the arc extinguishing chamber is a vacuum arc extinguishing chamber; a fixed end of the vacuum arc extinguishing chamber is provided with a vacuum inductor; one end of the vacuum inductor is connected with a short pin; and the short pin is U-shaped or cylinder-shaped or cone-shaped. According to the mechanism for facilitating circuit breaker detection of the utility model, a short pin which moves up and down vertically with the movable end of the arc extinguishing chamber is changed into the long pin, and therefore, test of a computer-type switch characteristic tester can be facilitated, and assembly detection efficiency and accuracy of data can be improved, and as a result, a problem of incapability of automatically testing data such as the opening distance and over travel of a circuit breaker, and a problem of low accuracy of testing data can be solved.
