The invention provides a wheel type electrical equipment creepage distance measuring device. The measuring device comprises a shell; the measuring wheel is arranged on the shell and is connected with the shell in a rotatable manner; and the angular displacement sensor is arranged on the measuring wheel. According to the invention, the measuring wheel is attached to the surface of electrical equipment to be measured and rotates from top to bottom along the outer insulation surface; when the measuring wheel rotates along the surface of the to-be-measured electrical equipment, the angular displacement sensor detects the rotation angle of the measuring wheel, obtains the travel of the measuring wheel walking along the to-be-measured electrical equipment, and further obtains the creepage distance of the to-be-measured electrical equipment. The creepage distance measuring device solves the problems of inaccurate measuring precision, inconvenient operation and the like when a conventional tool such as an adhesive ta
