What is dual power automatic transfer switch?
Dual-power automatic transfer switch is microprocessor, which is used to start and switch between grid power and grid power or between grid power and generator power supply in power grid system. It can supply power continuously. Series of dual power supply, when the common use of sudden failure or power outage, through the dual power automatic transfer switch, automatically put into the standby power supply (under small load standby power supply can also be supplied by generators), so that the equipment can still operate normally. The most common are elevators, fire protection, monitoring, lighting and so on.When the generator set is used as emergency lighting power supply, the start-up time and power conversion time of the generator should not exceed 15s. Double power automatic switching switch should choose "city power - generator conversion" special type.
Dual-power automatic transfer switch has the functions of short circuit and overload protection, over-voltage, under-voltage, phase-gap automatic conversion and intelligent alarm, automatic conversion parameters can be set freely outside, and intelligent protection of operating motor. When the fire control center gives a control signal to the intelligent controller, two circuit breakers enter the sub-unit. In the gate state, the computer network interface is reserved for the realization of remote control, remote adjustment, remote communication, remote measurement and other four remote functions.
Application
1.CJQ2 series terminal type dual power supply automatic transfer switch is suitable for 50Hz/60Hz, rated working voltage 220V (2P),380V (3P,4P), rated current 6A-630A terminal type double circuit power supply system.Automatic conversion between common power supply and backup power supply can be completed to ensure the reliability of power supply.
2.It is mainly used in high-rise buildings, shopping malls and other places such as fire pumps, smoke elimination fans, elevators, domestic water pumps, accident lighting, and distribution signs.
Features
1.High reliability: The terminal dual power supply can provide dual power supply. Once one power supply fails, the other power supply can continue to supply power, which improves the reliability of power supply.
2.Flexible power supply: The terminal dual power supply can select different power supplies for power supply as needed, and can be switched according to actual conditions, which improves the flexibility of power supply.
3.Convenient maintenance: The maintenance of the terminal dual power supply is relatively simple. Once a fault occurs, it can be quickly located and repaired, reducing maintenance costs and time.
Normal working conditions
1.Ambient air temperature: the upper limit does not exceed +40°C,the lower limit does not exceed -15°C, and the average value of 24 hours does not exceed +35°C;
2.Installation site: the altitude does not exceed 2000m;
3.Atmospheric conditions: The relative humidity of the atmosphere does not exceed 50% when the surrounding air temperature is +40°C. At a lower temperature, there can be a higher temperature. When the average minimum temperature of the wettest month is +25°C, the average maximum relative humidity is 90%, And taking into account the condensation that occurs on the surface of the product due to humidity changes,special measures should be taken;
4.Pollution level: lll level;
5.Installation environment: no strong vibration and shock at the operating site, no corrosion and harmful gases that damage insulation, no serious dust, no conductive particles and explosive hazardous substances, no strong electromagnetic interference;
6.Use category: AC-33iB
