Abstract
The utility model discloses an isolating switch three-phase linkage test device, which comprises a base, a main switch fixing platform, a static contact hanger and a main switch driving device, wherein the main switch fixing platform is fixedly arranged on the base, and a driving device fixing plate is vertically fixed on the base at one side of the main switch fixing platform; the main switch driving device can be movably arranged on the fixing plate, and a dynamic torque sensor is arranged on the power output shaft of the driving device; the main switch fixing platform is fixedly connected with a supporting rack, and the static contact hanger is arranged at the top of the supporting rack. With the structure, the main switch part of an isolating switch can be separated from the base and a porcelain insulator, the three-phase linkage mechanical property test of the main switch part can be separately carried out, and the synchronization requirement and other mechanical properties can be tested without fully assembling and installing all parts of the isolating switch; and meanwhile, the difference between switch-on and switch-off force moment of the main switch can be accurately measured, the labor intensity of the test is reduced, and the labor efficiency is improved.
Description
Technical field
The utility model relates to a kind of inspection of high-voltage switch gear, relates in particular to a kind of verifying attachment that three synchronised, divide-shut brake torque difference and dynamic/static contact contact situation are tested and measured.
Background technology
At present, known experimental examination method is a simulated field, all parts of disconnector are carried out Installation and Debugging according to the installation requirement at scene, check its three synchronised and other mechanical property then, but, it is big that all parts simulated fields of disconnector are carried out the Installation and Debugging workload, as the Installation and Debugging of a GW16-550 type disconnector, carry out workload 3 people that mechanical property detects and need 3 day time; Simultaneously, this detection method can not be checked single-phase divide-shut brake torque difference, and divide-shut brake torque difference classic method is to use spring balance to add torsion bar to carry out manual measurement.The measurement of manual measurement divide-shut brake torque difference is after the general assembly (GA) of main switch cutter, manual measurement out of true and dispersed big.
The utility model content
Task of the present utility model is: a kind of disconnector three-phase linkage test device is provided, reaches the coarse problem of divide-shut brake torque difference of measuring greatly to solve disconnector mechanical test workload.
The technical solution of the utility model is: a kind of disconnector three-phase linkage test device, comprise base, main switch cutter stationary platform and static contact hanger and main switch driving device for cutter, described main switch cutter stationary platform is fixedly mounted on the base, vertical fixing has a drive unit fixed head on the base of main switch cutter stationary platform one side, described main switch driving device for cutter is mobilizable to be installed on this fixed head, and the power output shaft of described drive unit is provided with the dynamic torque sensor; Described main switch cutter stationary platform also is fixedly connected with a bracing frame, and described static contact hanger is installed in the top of this bracing frame.
On described bracing frame, also be provided with debug platform, described debug platform is divided into upper mounting plate and lower platform, and wherein, upper mounting plate is installed in the position of close static contact hanger on the bracing frame, so that detect main switch cutter divide-shut brake situation, the position of the corresponding main switch cutter of lower platform is installed in the bracing frame middle part.
Described reducing gear is a turbine and worm motor deceleration mechanism.
Adopt said structure, do not need all parts of disconnector are installed according to the installation requirement at scene, the main switch cutter part of disconnector can be separated with its base and porcelain vase, carry out the three-phase interlocking mechanism performance test of main switch cutter part separately, check it to require synchronously and other mechanical property and each parts of disconnector all need not being assembled, simultaneously, also can accurately measure the divide-shut brake torque difference of main switch cutter by the dynamic torque sensor, alleviated the labour intensity of test, raise labour efficiency, the raising of product quality is very helpful.
