A speed measuring bracket for a switch characteristic instrument

Abstract

The invention discloses a switch characteristic instrument speed measurement bracket, which comprises a regulation fixing plate, a strut, a cylinder, a cylinder fixing plate, two spherical connection seats, a vertical connecting rod, a horizontal connecting rod, a C-shaped clamping seat, a plurality of screws, a plurality of screw caps and a plurality of nuts, wherein one end of the regulation fixing plate is fixed with the screw caps by the screws; the middle of the regulation fixing plate is provided with a groove along the length direction; the lower end of the strut is inserted into the groove; the cylinder is arranged above the strut; the side surface of the cylinder is provided with the cylinder fixing plate; the tail end of the cylinder fixing plate is connected with the first spherical connection seat; the lower end of the vertical connecting rod is inserted into the first spherical connection seat; the upper end of the vertical connecting rod is connected with a second spherical connection seat; the horizontal connecting rod is horizontally inserted into the second spherical connection seat; and the other end of the horizontal connecting rod is provided with the C-shaped clamping seat. According to the switch characteristic instrument speed measurement bracket provided by the invention, the data discreteness of the switch characteristic instrument is reduced, the accuracy is improved, and the switch characteristic instrument speed measurement bracket has the advantages of convenience in use and easiness in operation.

Description

technical field [0001] The invention relates to a support for a speed-measuring instrument of a high-voltage circuit breaker, in particular to a support for a speed-measuring instrument of a switch characteristic. Background technique [0002] High voltage circuit breaker is one of the most important control devices in power system. The number of high-voltage circuit breakers in the power grid is the largest, and the operating conditions and technical requirements are relatively complicated. Its operational reliability is not only related to the high-voltage circuit breaker itself, but also affects other equipment and even the entire power grid. Therefore, testing the dynamic characteristics of high-voltage circuit breakers is a very important task, but the traditional method of testing the dynamic characteristics of high-voltage circuit breakers has disadvantages such as complicated operation and low test accuracy. In order to solve these problems, high-voltage switch The ...

Problems solved by technology

In this way, many different brackets need to be made for different switches, and it is very difficult to install and disassemble on site.

At the same time, the existing switch characteristic meter speed measuring bracket generally uses the principle of electromagnet, but with the vibration of the switch opening and closing, the electromagnet will shift and the data will be discrete.
