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

Abstract

The invention discloses an auxiliary device for a carrying relay protection debugging instrument in the technical field of secondary debugging auxiliary equipment for substations. The bottom of the load-bearing underframe is provided with a climbing wheel set close to one side of the reversing frame, and the other side of the bottom of the load-bearing underframe is provided with adjustable feet. and the test line transfer mechanism of the grounding phase. The bottom of the load-bearing chassis is provided with a test line transfer mechanism that serves as the external ground of the relay protection debugger. Mechanism, with the carrying, operation and storage of the relay protection debugger and its related accessories.

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 ...
