Microcomputer simulation circuit breaker

Microcomputer simulation circuit breakerDetailed introduction:

1. This machine can be powered by AC/DC 110V-250V, making it convenient for users to use the DC power supply in the substation. AC power supply can also be used. Greatly convenient for users to use (please specify when placing an order).

2. This simulated circuit breaker input control terminal can input AC/DC current signals to trigger the action of the simulated circuit breaker. Thus, the operating characteristics of AC/DC circuit breakers can be simulated.

3. This simulated circuit breaker adopts a low-energy design and is equipped with a large capacity lithium battery. In the absence of AC power supply on site, it can be used continuously for more than 10 hours and standby for more than 30 hours. When using internal lithium power supply and external input power supply as DC, the DC output power supply provided by this machine is not available. (This function is an optional feature, please specify it when ordering)

4. This machine has a fault locking contact input port, which is convenient for users to use.

5. This device adopts a modular design, which can be infinitely expanded by adding tripping and closing modules and control units. It can form simulated circuit breakers with two or more circuits, and can form simulated circuit breakers with multiple circuits, thus simulating the actions of multiple three-phase circuit breakers. Multiple analog circuit breaker input and output circuits are isolated from each other, and when the tripping and closing coil currents are used in parallel through corresponding channels, the current can be doubled, thereby achieving more functions. It can also be used to form a simulated circuit breaker screen for teaching and experimental purposes.

In summary, this simulated circuit breaker can simulate the automatic reclosing test, automatic backup power input test, and three-phase synchronization test of AC/DC circuit breakers.
