Intelligent AC low-voltage switchgear is a kind of scientific and technological development equipment supported by the state. The transmission design institute is in accordance with the requirements of the national key technology innovation project plan. Combined with more than a dozen industry complete sets of plants to form a national joint design group, the latest generation of intelligent low-voltage complete sets of equipment that passed the type test and developed based on the specific conditions of the domestic industry. The product fully complies with the requirements of GB7251.1-1997 "Low-voltage switchgear and control equipment Part 1: Type test and partial type test equipment" and other standards. This product is suitable for all levels of power grids with AC 50HZ, rated voltage 660V and below, and rated current up to 4000A. It can be used as motor control center, power center, reactive power compensation, main power distribution device and distribution device.
Conditions of use The ambient air temperature must not exceed +40 °C, not less than -5 °C, and the average temperature within 24 h must not exceed +35 °C. The air is clean. At a maximum temperature of +40°C, the relative humidity must not exceed 50%. At lower temperatures, a greater relative humidity is allowed. Pollution degree 3. The altitude of the installation site shall not exceed 2000m.
What are his uses? GCK series switchgear is suitable for industrial and mining enterprises, three-phase AC frequency 50HZ, rated voltage 380V to 600V, primary power distribution of the power system and secondary distribution or control equipment with asynchronous motors as the main control objects; also suitable for stations and docks , High-rise buildings, especially suitable for group control systems and field control devices of electric motors in power plants, substations, petroleum, chemical, metallurgy, machinery, light industry production lines. If equipped with appropriate interfaces, they can also be connected with PC (program controller) or The computer processor constitutes an automatic control system for distribution.
What structural features does its machine have? The main feature of the control cabinet is that it can be flexibly combined according to the required circuit scheme of each unit, and once a failure occurs, the unit can be drawn out in a short time, replaced with a spare unit to continue to use, the same unit can be in any Interchangeable on the cabinet. Unit compartment equipment ventilation channel, the top of the cabinet is equipped with a pressure release device, which is used to release the high-pressure free gas generated during the internal failure of the power distribution cabinet
