Function tester for conventional stability control device

Abstract

The invention discloses a function tester for a conventional stability control device. The function tester comprises a tester body and a back side of the tester body is provided with a packing groove, and an internal wall of a side of the packing groove away from a packing groove opening is provided with a through-hole. The through-hole is connected with an inside of the tester body and the surrounding of the through-hole is provided with a threaded hole placed on the internal wall of the side of the packing groove far away from the packing groove opening. A card groove is arranged on a side of the tester body and is connected with the packing groove. A cover plate is actively arranged in the packing groove and the surrounding of the cover plate is provided with a fastening hole matched with the threaded hole. A fastener is installed in the fastening hole and the fastener comprises a fixed block which is pressed against a side of the cover plate away from the through-hole. A threaded rod is welded on a side of the fixed block closed to the through-hole. The function tester is convenient to disassemble, install, repair and change, capable of starting an overall test towards a function of the security stability control device, simple in structure and convenient to use.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a function tester for a conventional stability control device. Background technique [0002] The regional security and stability control device is the third line of defense for the safety protection of the regional large power grid. The function of the stability control device is changeable, and there are many lines to be tested. It is difficult for the general testing equipment to meet the requirements in the output circuit and functional test, which brings difficulties to the equipment testing, and cannot be easily installed and disassembled, resulting in inconvenient maintenance or replacement. [0003] Therefore, we propose a conventional stability control device function tester specially designed for the safety and stability device function to solve the above problems. Contents of the invention [0004] Based on the technical problems existing in the background tech...
