A DCS-Based Power Supply Switching Method

Abstract

The invention discloses a DCS-based power switching method, comprising: step 1, a data acquisition module collects the off state of the first switch and the current passing through it, the off state of the second switch and the current passing through it, and sent to the DCS controller; step 2, if the first switch has no current passing through, the DCS controller sends an instruction to close the second switch to the switch controller, which receives the instruction and closes the second switch; the present invention It can realize remote switching of the power supply in real time, switch the other power supply in real time when one power supply fails, avoid the impact of power disconnection on the external circuit, and set up an interlock switch, which improves the safety of power supply switching and avoids power failure in the circuit In the case of maintenance, the automatic switching of the power supply causes personal injury. The present invention overcomes the problems of high cost and many failures caused by the switching of the power supply switching device in the prior art, and has a good market application prospect.

Description

technical field [0001] The invention belongs to the field of power switching methods, and in particular relates to a DCS-based power switching method. Background technique [0002] With the rapid development of society, almost all walks of life are inseparable from electricity, while petrochemical, metallurgy, textile and other large-scale manufacturing industries have put forward higher requirements for the reliability and continuity of power supply. Bring huge economic losses, more importantly, may also cause personal injury accidents, resulting in irreparable losses. [0003] At present, power switching is mainly achieved by using power switching devices in the market, such as switch cabinets. However, this power switching method usually has the problems of high cost of power switching devices, easy switching failures, and poor safety of such switching devices. If one power supply is disconnected, the other power supply is switched directly, which is prone to personal in...

[0003] At present, power switching is mainly achieved by using power switching devices in the market, such as switch cabinets. However, this power switching method usually has the problems of high cost of power switching devices, easy switching failures, and poor safety of such switching devices. If one power supply is disconnected, the other power supply is directly switched, which is prone to personal injury accidents caused by automatic switching of the power supply during the maintenance process.
