Description

Technical Field

[0001] The invention belongs to the technical field of secondary debugging auxiliary equipment for transformer substations, and in particular relates to a carrying auxiliary device for a relay protection debugging instrument. Background Art

[0002] The relay protection debugging instrument is a special device for detecting and debugging relay protection devices in power systems. Relay protection devices refer to devices used in power systems to automatically detect faults and quickly cut off the faulty parts to protect equipment from damage. The debugging instrument can simulate various power system operating conditions and fault conditions to help engineers ensure that the relay protection devices can respond correctly and quickly, thereby ensuring the safe and stable operation of the power system. The debugging work of the relay protection device means that the relay protection personnel use the debugging instrument to input simulated voltage and current into the device or electrical equipment according to professional regulations and requirements, and then use the indoor device to collect electrical parameters to determine whether the protection can operate correctly, so as to timely cut off the fault and effectively reduce the economic losses of the power grid. Since the debugging work must be carried out when the equipment is out of power, the efficiency of this work affects the power transmission time and affects the life and production of users. The relay protection debugging instrument is a desktop instrument required for the debugging of relay protection devices. The debugging of relay protection devices is generally carried out at different locations outdoors, so a mobile mounting frame is required to facilitate the movement and carrying of the equipment. The existing mobile mounting frame is a trolley. Although the trolley meets the characteristics of mobility and portability, the relay protection debugging instrument is prone to sliding or even overturning when placed on the trolley going up and downhill or on uneven roads, which poses a safety hazard to the use of the equipment. Summary of the invention
