The invention discloses an automatic multipoint power supply switching system for a crown block sliding wires. The system comprises a crown block current-collector arranged on the crown block, a proximity switch sensing steel plate, an insulated isolation device, short sliding wires being 1.8m, a power switching device, a proximity switch A, a proximity switch B and a proximity switch C. According to the automatic multipoint power supply switching system, the sliding lines are divided into a plurality of sections for power supply; if even one of the sections is in power failure, the other sections can not influence the work of the crown block, the degree of automation of the crown block is improved, the power supply loss is reduced, the voltage on the sliding wire is not changed all the time when the crown block runs from a starting point to a terminal, and no influence on crown block devices can be caused. The automatic multipoint power supply switching system disclosed by the invention is particularly suitable for the crown block, and the longer the sliding lines are, the more obvious the advantages are.
