The high-voltage complete sets of equipment are mainly used for the control and protection of power systems (including power plants, substations, transmission and distribution lines, industrial and mining enterprises and other users). Part of the power equipment or lines can be put into or out of operation according to the needs of grid operation, or can be used in when the power equipment or line fails, the faulty part is quickly removed from the power grid, so as to ensure the normal operation of the fault-free part of the power grid and the safety of equipment and operation and maintenance personnel.
The low-voltage complete sets of equipment are widely used in power distribution, electric drive and automatic control equipment of low-voltage systems in power plants.
The series products use the structural section combination as the basic framework. All structural components are fixed with screws. After forming the basic framework, the doors, baffle, clapboard, drawer, mounting bracket, busbar and electrical components are fixed as required to make up the complete switchgear;
The framework uses rolled section. Positioned by three-dimensional board, and connected by bolt, without welding structure, in order to avoid welding deformation and stress and improve the installation accuracy;
All internal structure are galvanized, the external structure are sprayed with static epoxy powder after pickling and phosphating treated;
For indoor use, the elevation of using site ≤ 2000m (above this can be negotiated);
The relative humidity should not exceed 50% at +40℃, while at lower temperatures, larger relative humidity is acceptable, e.g. 90% at +20℃. Considering the change of temperature may sometime cause the condensation, the daily average should be less than 95% and the monthly average less than 90%.
