Abstract

The invention discloses a DCS uninterruptible power supply control system of a PTA device, which includes an uninterruptible power supply I, an uninterruptible power supply II, a dual-power-supply conversion switch, a load I and a load II. The structure of the uninterruptible power supply I is the same with that of the uninterruptible power supply II. The uninterruptible power supply I is connected with one end of the dual-power-supply conversion switch, and the other end of the dual-power-supply conversion switch is connected with the load I. The uninterruptible power supply II is connected with one end of the dual-power-supply conversion switch and the load II. Because the power supply mode of the load I carried by the uninterruptible power supply I is changed, another power supply is added. The added power supply is realized by the dual-power-supply automatic conversion switch. Under normal circumstances, the two uninterruptible power supplies supply power to their respective loads.When the uninterruptible power supply I fails and has no output, the dual-power-supply automatic conversion switch detects the fault and switches the system to the uninterruptible power supply II forpower supply. Thus, the reliability of power supply is greatly improved, and the power supply of the uninterruptible power supply II itself will not be affected.

Description

technical field [0001] The invention relates to the technical field of PTA production, in particular to a DCS uninterruptible power supply control system for a PTA device. Background technique [0002] In order to maximize production capacity and maximize the utilization of public resources in the current PTA industry, several sets of PTA devices will be built together to ensure production, reduce consumption, and increase the competitiveness of the industry. Due to the particularity of the process characteristics of the PTA refining unit and the risk of a long operation period, coupled with the instability of the operation, some unexpected problems will occur in some of the main equipment and catalysts in the unit, which requires a short time for the refining unit to Stop for maintenance. The overhaul of the refining unit will cause the oxidation unit to be shut down, which means that the output will be reduced and the consumption will increase fearlessly. According to in...
