Description

Technical Field

[0001] The present invention belongs to the technical field of inspection vehicles, and in particular relates to an intelligent complete equipment inspection vehicle. Background Art

[0002] In the power industry, complete sets of equipment below 35kV are widely used in power systems such as substations and distribution stations. The factory inspection of these equipment is crucial to ensure the safe operation of the equipment in the power system. Traditional inspection methods usually rely on manual inspection, which is not only inefficient, but also may have safety hazards and data accuracy issues. Therefore, with the development of science and technology, automation and intelligent detection technology are gradually applied to the inspection field of power equipment.

[0003] At present, the switch cabinet power-on inspection vehicle is usually used in the market to conduct various power-on tests on the high and low voltage switch cabinets produced by complete switch cabinet manufacturers before they leave the factory. It can provide various AC power supplies and DC power supplies to facilitate the power-on test and detection of the switch cabinet, and greatly improve work efficiency while ensuring the safety of the test personnel. The switch cabinet power-on inspection vehicle is mainly composed of a control system and a test device. The control system is the brain of the inspection vehicle, responsible for adjusting and managing the entire test process. The test device includes the part that provides power and the wiring part connected to the switch cabinet being tested.

However, the manual control method has low working efficiency and is not convenient for emergency stop operation in an emergency. There are certain safety hazards. Therefore, we need to propose an intelligent complete equipment inspection vehicle that can use electric control to control the current output of the inspection vehicle.
