Description

Maintenance platform for wind tower converter cabinet and use method Technical Field The invention relates to the technical field of electronic power maintenance, in particular to a maintenance platform for a wind tower converter cabinet and a use method thereof. Background The converter is a core device for converting one form of energy, signal or substance into another form, and is widely applied to a plurality of fields of electronics, power, industrial production, daily life and the like, and the core principle of the converter is unfolded around energy conservation, signal modulation or substance form conversion. Converter cabinets are used for integration, device and protection of converters. In the fan tower, the converter cabinet bears static load of heavy equipment such as a converter and vibration load generated by fan operation for a long time, structural fatigue, weld cracking and bolt loosening are easy to occur, and in addition, the fan tower is often in a severe environment (such as offshore high-humidity high-salt mist and onshore high-temperature high-sand dust), so that the converter cabinet is affected. As is well known, the space in the fan tower is very narrow and small, the converter cabinet is required to be maintained when failing, the operation personnel is required to operate and maintain at the top of the converter cabinet, the existing maintenance device for the converter cabinet is often integrally arranged, and therefore the problems of in-out and inconvenient use exist when the operation personnel uses the maintenance device in the narrow space. Disclosure of Invention The invention provides a maintenance platform for a wind tower converter cabinet and a use method thereof, which aim to solve the problems that the space in a wind tower cylinder is very narrow, the converter cabinet is required to be maintained when a fault occurs, an operator needs to perform operation maintenance on the top of the converter cabinet, and the existing maintenance device for the converter cabinet is often integrally arranged, so that the operator has inconvenient in and out and use when using the maintenance device in the narrow space.
