    AbstractThe lightning protection measures of outdoor air conditioners and outdoor box-type transformers are discussed and it is proposed that the sideflash prevention measures are required for the outdoor air conditioners protruding from the external walls in high-rise buildingsan appropriate surge protective device shall be selected on the low-voltage side of the outdoor box-type transformer in order to prevent forward transformation overvoltage. The reasons for the failure of the surge protection of the control cabinet in the elevator machine room are analyzedand the corresponding solutions are given through the actual project case.
