The power frequency electromagnetic field generation platform comprises an electric field generation apparatus, a magnetic field generation apparatus and a movable plastic object-placing vehicle, the electric field generation apparatus comprises an insulator, an electric field generation apparatus upper pole plate, an electric field generation apparatus lower pole plate and a support frame, the electric field generation apparatus upper pole plate is vertically suspended on a top beam of a laboratory through the insulator by employing an laboratory top beam hoisting mode, the electric field generation apparatus lower pole plate is horizontally arranged on the support frame and parallel to the upper pole plate and used for generating an electric field in a vertical direction, the magnetic field generation apparatus comprises magnetic field generation coils arranged at the left side and the right side of the electric field generation apparatus with an equal interval in a vertical manner and is used for generating a magnetic field in a horizontal direction, andthe movable plastic object-placing vehicle is arranged at the very center of the electric field generation apparatus lower pole plate and used for placing test equipment. According to the power frequency electromagnetic field generation platform, simultaneous output of the power frequency electric field and the magnetic field of the site of the substation can be simulated, and a laboratory powerfrequency electromagnetic field environment is provided for the metering characteristic research of various high-voltage test devices such as live detection / online monitoring devices in a high power frequency electromagnetic field environment of the site of the substation.

Description

technical field [0001] The invention relates to the technical field of high-voltage metering, in particular to a power-frequency electromagnetic field generating platform for simulating substation sites, which is used to assess various types of high-voltage test equipment (such as various live detection / online monitoring equipment) under power-frequency electromagnetic fields performance of the measurement accuracy. Background technique [0002] At present, in the laboratory, the inspection of the high-voltage test equipment used in the substation, such as on-line monitoring of dielectric loss, live detection / on-line monitoring of lightning arresters, and on-line monitoring of iron core grounding current, is to output standard current or standard voltage through standard sources. In the testing process, the influence of the on-site electromagnetic environment was not considered, because the laboratory lacked a power-frequency electromagnetic field generator that simulated ac...
