The utility model relates to a movable type power frequency pollution deposit test power supply system which is composed of a container, an operating console, a low-voltage switchgear, a voltage regulator, a power frequency transformer, a protection resistor, a power frequency voltage divider and a power frequency lead-out bushing. The movable type power frequency pollution deposit test power supply system is characterized in that a power frequency test power supply is mounted in the container for meeting requirements for a movable-type on-site test; the container adopts the design structure that a container body and a container pedestal are separated; and the container body and the container pedestal are fixed using 24 rapid container lockers. According to the movable type power frequency pollution deposit test power supply system, a 50Hz power frequency power supply is used for obtaining high voltage, is good in quality and large in capacity and can meet research requirements of a pollution deposit test; the design of the movable-type container is adopted, so that rapid layout can be achieved on a site for carrying out a test, and the on-site workload is reduced; and a generator can be used for power supply, so that the movable type power frequency pollution deposit test power supply system can be used in an area without power supply.
