KYN28A-12(Z)(GZS1) steel-clad movable-type AC metal-enclosed switchgear (“switchgear” for short) is applicable for three-phase AC50Hz power systems and used for receiving and distributing electric energy and controlling, protecting and monitoring a circuit.Normal Usage Conditions
1. Ambient air temperature: maximum temperature of +40¡æ and minimum temperature of -15¡æ.
2. Relative humidity:
Daily mean relative humidity: ≤95%
Daily mean water vapor pressure: not more than 2.2KPa
Daily mean relative humidity: ≤90%
Daily mean water vapor pressure: not more than 1.8KPa
3. Altitude: less than 1000m
4. Seismic intensity: not more than 8 degrees
5. Ambient air is not polluted by corrosive or combustible gas, water vapor and so on obviously.
6. Places without violent vibration
Structural features
The structure of the switchgear is shown in the following figure. An all-metal modular assembled structure is adopted, and the cabinet body is made from an imported aluminum-zinc coated plate with strong corrosion resistance, does not need surface treatment, is processed by CNC high-accuracy equipment, adopts an advanced multiple folding process, uses rivet nuts and high-strength bolts for connection, and has high accuracy, light weight and good strength.
