Description

technical field

[0001] The invention relates to a relay protection test, in particular, a relay protection test vehicle which centrally installs various instruments and equipment required for the relay protection test with an AC voltage level of 500kV and below on a motor vehicle. Background technique

[0002] During on-site inspection of relay protection, in order to conduct primary side flow test, protection device insulation, zero drift, sampling accuracy, logical judgment, and action behavior inspection, a complete set of inspection equipment is required. At present, the basic situation of relay protection inspection work is: the equipment required for relay protection inspection is stored in the warehouse. Before work every day, the working team will manually transport the equipment from the warehouse to ordinary motor vehicles. After the work of the day is over, the equipment is carried back to the company and then unloaded and put back into the warehouse. There are m...
