Problems solved by technology
[0003] In the previous motor heat dissipation device, it was necessary to regularly clean the heat dissipation network port and cooling fan of the power distribution cabinet, which was cumbersome to operate and the cleaning efficiency was low. In addition, when the unused power distribution The continuity causes moisture and dust accumulation of internal components, which reduces the service life of the shelving distribution box when it is used next time

The invention discloses a heat dissipation device for a power distribution cabinet of a steam-electricity double-drive steam turbine. The device comprises a power distribution cabinet, a heat dissipation net opening is fixedly formed in the side wall of the power distribution cabinet, and a fan blade cleaning assembly used for blowing and cleaning heat dissipation fan blades is arranged in the power distribution cabinet. And moisture-proof dust removal through collision dust removal and accompanying sealing is arranged in the power distribution cabinet. Through the cooperation among an air inlet, an inner sliding rod, a pneumatic spring and a ventilation assembly, the blowing cleaning function of a cooling fan when the cooling fan stops working is realized by utilizing the wind power of the cooling fan and the elastic extrusion between pneumatic springs, so that the timely fan blade cleaning effect is achieved after each cooling is finished; and in addition, through the cooperation of a rolling rotating wheel, a driving rope, a driving assembly and a sealing assembly, and through the driving rolling generated by wind power, the accompanying opening and closing function that a dustproof baffle is opened when the cooling fan works and closed when the cooling fan stops working is achieved.
Description
technical field [0001] The invention relates to the technical field of power distribution cabinet heat dissipation, in particular to a heat dissipation device for a power distribution cabinet of a steam-electric dual-drive steam turbine. Background technique [0002] The purpose of setting up the power distribution cabinet is to facilitate the distribution of power by the system. When the line fails, it is beneficial to control the scope of the fault, and it is convenient to quickly find out the fault point and eliminate it in time. There is no need to carry out large-scale power outage operations. The main components of the power distribution cabinet include: terminal blocks, various knife switches, protection equipment, measuring equipment, metering equipment, and various protection equipment. The protection equipment includes fuses to prevent short circuits and prevent Overloaded air switch. [0003] In the previous motor heat dissipation device, it was necessary to regu...
