The emergency power supply configured by chemical enterprises is:
The emergency power supply consists of chargers, inverters, batteries, isolation transformers, switches and other devices, which can reverse the DC power supply into AC power supply. Suitable for loads with power off time greater than 0.25 seconds
Two, UPS uninterruptible power supply:
Third, the enterprise's own emergency diesel generator set:
With diesel engine as the power, the power generation device of frequency AC synchronous generator is towed. The self-starting generator set is suitable for buildings with power outage of more than 15s. The working time of the emergency power supply should be considered according to the power failure time allowed by the production process, and should not be less than 10 minutes when used with the automatic start generator set.
A special feed circuit with an automatic switching device independent of the normal power supply. The operating time of the automatic switchgear can meet the emergency power supply with the allowable power failure time of 1.5s or 0.6s or more If the DC power supply can be used for particularly important loads with the allowable power failure time of milliseconds and small capacity, the battery pack should be used as the emergency power supply.
