of Course, we all always want to any external circumstances have not made discomfort routine. To such circumstances is not only off the water or heating but of course the power outage. The last trouble may not just spoil a cozy evening, but also seriously damage sensitive plans.
However, in some cases, the disappearance of electricity is simply unacceptable, and in such situations, you need a backup option that will provide uninterrupted power to the grid. For solving such problems are designed Cabinet automatic power reserve, which will switch the power from the disconnected line on the feed.
How does the ATS work?
There are several schemes which can operate similar equipment. Wiring diagrams come with the metering devices or metering devices. But also apply schemes with multiple inputs involving the main input and backup input.
In cabinets automatic transfer switch with standby and primary electrical inputs during normal operation, electricity passes through a line circuit breaker in a pair of contactor. These devices in the event of a power outage at the main input switch power from the main to the backup input. If the power on the main input is restored the switch to normal operation occurs automatically.
In cabinets automatic transfer switch, which is working on the scheme with sectional switch, both electric input in normal operation are working, and the sectional switch comes off. However, the disappearance of electricity on one of the two inputs of the contactor is de-energized input is disabled, and contactor sectional Vice versa, switches to the "on" position. In the case where the power supply is restored, the switches are triggered in reverse order.
In cabinets automatic transfer switch with installed metering devices input devices installed to disconnect the load and input circuit breakers 10 kA or more.
Where applicable cabinets ABP?
These devices work effectively where necessary to ensure continuous current supply switching from 32 to 630 amp method transfer to a backup power source and disconnect from the main power line. At the end of the emergency situation the device shall automatically restore the usual power scheme from the main entry.
