The system comprises a phytotron body (1), a wall bushing (2) for leading-in the power supply, a wind speed simulation apparatus (3), a refrigeration system (4), an evacuation system (5), a steam fog system (6), a water treatment system (7), an ice coating, fog spraying and raining system (8), a hook and rotating apparatus (9) and a test environment measurement system (10). The large-scale multifunctional phytotron system of the utility model enables to simulate altitude of 232 to 7000m, atmospheric pressure of 98.6 to30KPa, temperature of -45 DEG C to 70 DEG C, wind speed of 0 to 12m / s and water electrical conductivity of 10 to 5000MuS / cm, and enables simulation and regulation of complex meteorological environment such as high altitude, ice coating, fog spraying, raining and other environments.

Description

technical field [0001] The invention belongs to the technical field of high voltage and insulation, in particular to a manual simulation test system for the external insulation of power transmission and transformation equipment in complex atmospheric environments. Background technique [0002] The external insulation of the power system in operation is inevitably affected by complex meteorological conditions such as high altitude, ice (snow), acid rain (acid fog), pollution, etc., which seriously threaten the safe and reliable operation of the power system. On-site operation experience shows that meteorological conditions such as high altitude, icing (including icing type, icing period, icing period, icing water conductivity, and icing degree), pollution (including fog concentration, acid rain, and acid fog) have great impact on power generation. The electrical performance of the external insulation of the system is seriously affected. [0003] The artificial simulation tes...

AI Technical Summary

Problems solved by technology

The above two simulated environment devices do not consider the altitude problem, so they can only simulate the altitude of the device location, and because there is no power supply device and power introduction device, it cannot be used for external insulation of power systems in complex environments electrical test

[0004] So far, there are many kinds of artificial climate chambers for simulating a single environment such as high altitude, icing, and pollution. The existing test devices at home and abroad are mainly developed for a single environmental condition (such as icing or pollution or high altitude). , its function is far from meeting the actual needs of the electrical test research on the external insulation of the power system
