Design of Smart Hoisting Apparatus for Valve Cooling Main Pump in UHV Converter Station
A smart hoisting apparatus suitable for valve cooling main pumps of ultra-high voltage converter stations is de-signed to address the current situation of insufficient hoisting methods,low smartization and low work efficiency in main pumps maintenance.First the composition of valve cooling system and problems existing in hoisting installation of its main pump are analyzed.Second based on the ideas of smartization,high efficiency,and ease of operation,by separating the hoisting platform from the operating terminal,the functions,overall architecture,power source,information acquisition and transmission scheme of the hoisting apparatus are designed.On this basis,the recommended hoisting installation strategy is given by employing a case of main pump disassembly.Finally a three-dimensional simulation is conducted on the smart hoisting apparatus,and a comparison is made between the new hoisting installation schemes and the currently prevailing disassembly and assembly schemes for valve cooling main pumps.It can be concluded that the designed appara-tus is of high smartization and efficiency as well as wide application range and significant promotion potential,as it can carry out hoisting work without relying on on-site power supply.
