1. Product Overview
Dual power supply is mainly pided into PC-level dual power supply (integral type) and CB-level dual power supply (dual circuit breaker type)
(1) PC-level dual power supply: dual power supply that can be turned on, carried, but not used to break short-circuit current
Dual power supplies: If a load switch without an overcurrent release is selected as the actuator, it is a PC-grade automatic transfer switch. It does not have a protection function, but it has a high tolerance and switching ability, which can ensure the safety of the switch itself, not damaged by faults such as overload or short circuit, and ensure a reliable switching circuit in this case.
(2) CB level dual power supply: dual power supply equipped with overcurrent tripper, its main contact can be turned on and used to break short-circuit current
If a circuit breaker with an overcurrent release is selected as the actuator for dual power supplies, it is a CB class automatic transfer switch. With selective protection function, it can provide short circuit and overload protection for the load and cable at the lower end; Its turn-on and breaking capacity is much greater than the use of other components such as contactors and relays.
Dual power automatic switching device (ATSE), is the introduction of foreign advanced technology, the use of the United States MIC company cutting-edge technology chip micro-processing system as the core, set switch and intelligent controller in one, no additional controller, panel LCD display, full Chinese menu operation, truly realize mechatronics automatic transfer switch, with voltage detection, frequency detection, communication interface, remote fire interface, electrical, mechanical interlock and other functions, can realize automatic, electric remote, emergency manual control.
The operation is realized by the logic control board with various logic commands to manage the operation of the motor and gearbox, the motor drives the switch spring energy storage, instantaneous release of the acceleration mechanism, quickly turn on the breaking circuit or carry out circuit conversion, through the obvious visible state to achieve safety isolation, greatly improve the electrical performance and mechanical properties.
The overall design of the switch below 100A is a metal housing, which is small and robust. 125A and above switch, the control part is a metal shell, the switch part is made of unsaturated polyester glass fiber resin to make the shell, which has strong dielectric properties, protection ability and reliable operation safety.
2. Product use
Mainly used in critical power supply systems, it is a switch that automatically switches the load circuit from one (common) power source to another (backup) power supply to ensure continuous and reliable operation of important loads.
The switch is suitable for the automatic conversion of the main power supply and the backup power supply of the power supply system of laboratories, laboratories, clean rooms, computer rooms, colleges and universities, scientific research, industrial and mining enterprises and civil buildings, or the automatic conversion and safety isolation of two load equipment.
The switch has beautiful shape, novelty, simplicity, small size and full function, which is an ideal choice for similar products.
1. Building block switch body structure, small size, light weight;
2. Using excitation drive, the coil is instantly charged to complete the conversion, the conversion speed is fast, energy saving and environmental protection;
3. Pat-on dynamic and static contact structure, fast separation, conducive to contact arc extinguishing;
4. Unique silver alloy contact material, improve the arc resistance and oxidation resistance of the contact;
5. Equipped with independent arc extinguishing cover, arc extinguishing quickly, good protection of contacts, improve service life;
6. "V" type control mechanism to ensure that the two power supplies will not be turned on at the same time.
