It used to be a chlor-alkali plant, with traditional high and low voltage bus couplers (manual) and ATS switching devices (automatic). The common feature is that the switching time is relatively long; any fault in any section of the power supply will result in a shutdown of the entire system. Switching to another power source is also merely a measure to enable the motor to be restarted in batches as part of emergency handling. The new project falls under the category of fine chemicals, involving high temperatures and pressures, and is therefore very dangerous. The electricity consumption is relatively low. Now consider this: 1. The more important equipment, as well as those whose operation is triggered by power outages, are powered via STS static switches. This allows for a switching time of just a few milliseconds in the event of a power outage in any supply line, ensuring that these important devices remain powered. 2. Set the bus coupler to automatic mode; after the switch is made, the power supply is restored, and then the DCS is used to restart the devices that have stopped, thereby ensuring that the production system continues to operate without interruption. Prerequisite: The transformer meets the required standards. Is this approach feasible? What factors have not been taken into account? What additional equipment is needed to achieve such continuous production?
