Description

Double-power supply switching device

Technical field

The utility model relates to a kind of double-power supply switching device.

Background technology

At present, the application of DCS control system furthermore achieved that and the automation of control system simplifies EOP, improves reliability and the economy of gen-set.Due to computer-controlled high concentration, make it very high to the requirement of power supply, not only require power good, require reliable, every minute and second does not stop simultaneously.If power cut-off, just mean that DCS control system is paralysed, the lighter causes shutting down, and severe one may cause unit out of control, causes catastrophic consequence.Unit operation so far, due to configuration when DEH dispatches from the factory, when causing DEH rack UPS dead electricity, by loss redundant manipulator and all T equipment, produces not predictable risk to the stable operation of unit.

Utility model content

For solving the problems of the technologies described above, the utility model proposes a kind of double-power supply switching device, this device makes out-put supply more stable.

In order to achieve the above object, the technical solution of the utility model is as follows: a kind of double-power supply switching device, comprise four power modules and three redundant power handover modules, wherein four power modules are respectively the first power module, second source module, the 3rd power module and the 4th power module, and three redundant power handover modules are respectively the first redundant power handover module, the second redundant power handover module and triple redundance electrical source exchange module;

The two-way power supply of electric power incoming line one accesses the input of the first power module, second source module respectively, and accesses the input of the first redundant power handover module and the second redundant power handover module through the output of the first power module, second source module; Wherein output OUT1 with OUT2 of the first power module is connected with the input IN1 of the second redundant power handover module with the input IN1 of the first redundant power handover module respectively, and the output OUT1 of second source module is connected with the input IN1 of triple redundance electrical source exchange module;

The two-way power supply of electric power incoming line two accesses the input of the 3rd power module and the 4th power module respectively, and accesses the input of the first redundant power handover module, the second redundant power handover module and triple redundance electrical source exchange module through the output of the 3rd power module the 4th power module; Wherein the output OUT1 of the 3rd power module accesses the input IN2 of the first redundant power handover module, its output OUT2 accesses the input IN2 of the second redundant power handover module, and the output OUT2 of the 4th power module accesses the input IN2 of triple redundance electrical source exchange module;

The two-way power supply of electric power incoming line one and electric power incoming line two exports a road power supply respectively after three redundant power handover modules, and external triple redundance equipment R, triple redundance equipment S and triple redundance equipment T.

The beneficial effects of the utility model:

The power transfer device of this patent achieves the requirement of triple redundance equipment to power supply reliability, achieves the no-harass switch of duplicate supply, adds the reliability of the out-put supply of this equipment, ensure that the reliable and stable operation of DCS, DEH dispatch control system.
