An acceleration sensor positioning platform for circuit breaker spring operating mechanism

Abstract

The invention discloses an acceleration sensor positioning platform for a breaker spring operating mechanism. The acceleration sensor positioning platform is characterized in that the accelerometer positioning platform comprises a left clamping block and a right clamping block; a quarter sphere groove is formed at one side approaching the top surface of the left and right clamping blocks, and is connected with the side; a positioning ball is arranged in a half-sphere groove encircled by the quarter sphere groove of the left and right clamping blocks; the positioning ball can be fixed in the half-sphere groove through fastened connection of the left clamping block and the right clamping block through a fastener; and the upper end of the positioning ball is fixedly connected with a platform which is provided with an acceleration sensor through a quarter butt. The acceleration sensor positioning platform for a breaker spring operating mechanism can provide a mounting platform when an acceleration sensor is arranged on an energy storage spring of the breaker spring operating mechanism, and enables the acceleration sensor and the moving direction of the spring to maintain in the mutually parallel direction or the same horizontal line, and can guarantee that the accelerated speed during the moving process of the energy storage spring can be accurately measured.

[0002] At present, the monitoring of the mechanical characteristics of the circuit breaker spring operating mechanism in the power system generally only focuses on the measurement of parameters such as opening and closing time and speed, and does not monitor the acceleration of the action process of the energy storage spring of the operating mechanism.

For the relationship between the operating force and resistance of the energy storage spring, it can be monitored through the acceleration change in the action process, and the measurement of the acceleration change requires the installation of an acceleration sensor at the active end of the spring. The technical means of adding an acceleration sensor. In the prior art, when an acceleration sensor is installed on the spring of the circuit breaker spring operating mechanism, the acceleration sensor is simply fixed on a certain plane at the movable end of the spring under test, but because the plane It is not exactly perpendicular to the direction of motion of the spring, so that the direction of motion of the acceleration sensor and the spring is not in a parallel direction, so the acceleration sensor cannot obtain a good acceleration response, and cannot accurately measure the acceleration of the energy storage spring during the action process
