Summary:The utility model discloses a power supply lightning protection case and a power supply system of a machine room, wherein the power supply lightning protection case comprises a lightning protection module (10), and a main branch communicating with an input end and an output end of the power supply lightning protection case. The main branch is sequentially connected with the lightning protection module (10) and a low pass filter (20), and the lightning protection module (10) and the low pass filter (20) are grounded. When the low pass filter is serially connected in the power supply lightning protection case, current with low frequency is allowed to pass through during thundering and lightning days without cutting off power supply, thereby ensuring continuous power supply for a machine room by the machine room power supply system.
