Auxiliary device for carrying relay protection debugging instrument

Abstract

The invention discloses an auxiliary device for carrying a relay protection debugging instrument, belonging to the technical field of secondary debugging auxiliary equipment for substations. The auxiliary device comprises a load-bearing underframe, wherein one side of the top of the load-bearing underframe is hinged with an overturning frame through hinges; the top of the overturning frame is provided with a handle; one side, close to the overturning frame, of the bottom of the load-bearing underframe is provided with a climbing wheel set; an adjustable foot support is arranged on the other side of the bottom of the load-bearing underframe; four test wire switching mechanisms which serve as an A phase, a B phase, a C phase and a grounding phase respectively are arranged on the overturning frame side by side; a test wire switching mechanism which serves as external grounding of the relay protection debugging instrument is arranged at the bottom of the load-bearing underframe; and four groups of fixing mechanisms corresponding to four corners of the relay protection debugging instrument are arranged on the load-bearing underframe. The auxiliary device of the invention can realize carrying, operation, storage and arrangement of the relay protection debugging instrument and related accessories thereof.

Description

technical field [0001] The invention relates to the technical field of auxiliary equipment for secondary commissioning of substations, in particular to an auxiliary device for a commissioning instrument for carrying relay protection. Background technique [0002] Debugging of relay protection devices, that is, the relay protection personnel use the debugger to input analog voltage and current to the device or electrical equipment according to professional regulations and requirements, and then use the indoor device to judge whether the protection can operate correctly by collecting electrical parameters. In this way, the fault can be removed in time, and the economic loss of the power grid can be effectively reduced. Since the commissioning work must be carried out when the equipment is powered off, the efficiency of this work will affect the power transmission time and affect the life and production of users. [0003] The relay protection debugging instrument is a desktop ...

AI Technical Summary

Problems solved by technology

[0005] The relay protection debugging instrument is a desktop instrument and equipment required for the debugging of relay protection devices. The debugging of relay protection devices is generally carried out in different places outdoors, so a mobile mounting frame is required for the equipment to be moved. The mobile placement frame is a small trolley. If the small trolley encounters high sills and steps during the push and pull process, it will be difficult to pass smoothly. The inclined state prevents the debugger equipment on the carrier from tilting, making it inconvenient to operate
