Description

Relay protection test line auxiliary device Technical Field The invention relates to the technical field of auxiliary devices, in particular to a relay protection test line auxiliary device. Background The relay protection test line auxiliary device is widely applied to test and maintenance work of relay protection equipment, a relay protection system is an important component for guaranteeing safe operation of the equipment in an electric power system, the test line plays a key role in verifying whether the system can work normally or not and ensuring that a protection function is achieved, in the actual operation process, the relay protection test line is required to be accurately and reliably clamped and positioned so as to be prevented from being mistakenly operated or falling off, in the prior art, although some devices can fix and clamp the test line, the problems of low precision, unstable clamping, complex operation and the like exist in most of the devices, particularly when the test line with different models and sizes is faced, the adaptability of the existing device is poor, the adjustment cannot be flexibly carried out, the falling off or unstable clamping of the test line is easy to be caused, and the accuracy and the safety of the test are affected. Disclosure of Invention The utility model aims to provide an auxiliary device for a relay protection test line, so as to solve the problems in the background technology. In order to achieve the purpose, the relay protection test line auxiliary device comprises a mounting seat, wherein connecting grooves are formed in the front side and the rear side of the upper portion of the mounting seat, connecting shafts are connected inside the connecting grooves in a sliding mode, connecting plates are fixedly connected to the upper portions of the connecting shafts, mounting columns are fixedly connected to the upper portions of the connecting plates, clamping jaws are uniformly and fixedly connected to the opposite sides of the mounting columns, driving assemblies are arranged inside the mounting seat and used for driving the connecting shafts, fixing plates are uniformly and fixedly connected to the left side and the right side of the mounting seat, mounting rods are fixedly connected to the upper portion and the lower portion of the inside of the fixing plates, springs are sleeved on the front side and the rear side of the outer sides of the mounting rods, and limiting assemblies are arranged on the outer sides of the mounting rods and used for limiting the test line.
