Description

Technical Field

[0001] The utility model relates to the technical field of electric power equipment, in particular to a mobile AC / DC modulation trolley. Background Art

[0002] The most important feature of the mobile AC / DC modulation trolley is its light weight and easy mobility. It is suitable for different sites, and is especially convenient for debugging and repairing the control and protection panel cabinets of the outdoor secondary equipment of the power system in the debugging center. The trolley is mainly composed of a detachable equipment platform, simulated circuit breakers, simulated knife switches, PDUs, etc.

[0003] During use, the mobile AC / DC modulation cart needs to be started by a worker and moved to the area that needs debugging before debugging.

During movement, it is easy to block the user's line of sight, causing the cart to deviate from the route and collide with other equipment, causing damage to the equipment. In addition, the existing carts do not have corresponding protective measures for the worker's operating area. During the operation, the worker is likely to fall off the cart due to the bumps on the road and be injured. Utility Model Content
