UPS power distribution system

Abstract

The invention discloses a UPS power distribution system. The UPS power distribution system comprises a power distribution box and a UPS power supply apparatus; the power distribution box comprises a microprocessor, a camera, an image processing unit, a storage unit, a first power supply circuit, a second power supply circuit, an automatic selector switch, a communication unit, a display module anda reset key; the microprocessor, the camera, the storage unit, the first power supply circuit, the communication unit, the display module and the reset key are connected with the image processing unit separately; the second power supply circuit, the automatic selector switch and the microprocessor are connected in sequence; the first power supply circuit and the second power supply circuit are electrically connected with the mains supply separately; and the automatic selector switch is connected with the UPS power supply apparatus. When the microprocessor detects that the UPS power supply apparatus is in an abnormal state, the mains supply is switched automatically for supplying power, thereby avoiding power supply interruption, and ensuring stable operation of the power distribution system; and meanwhile, the condition of the power distribution box can be monitored remotely through the camera, so that convenience in maintenance is achieved.

Description

technical field [0001] The invention relates to the technical field of power distribution, in particular to a UPS power distribution system. Background technique [0002] During the operation of the power system, due to lightning strikes, short-circuit to ground, fault reclosing, standby automatic switching, external or internal power grid faults, large-scale equipment start-up, etc., the voltage may fluctuate instantaneously or be cut off for a short time. In just a few seconds, it is catastrophic for enterprises that require a large number of equipment in continuous production that do not allow the motor to trip and shut down in the technological process. The light ones are hundreds of thousands or tens of millions of economic losses, and serious fires, explosions and even Personal safety. [0003] Currently, an uninterruptible power system (UPS) is generally used in this field to supply power to different devices and different users. However, the currently used dual UPS...

Problems solved by technology

However, the currently used dual UPS power distribution system often only uses one power supply. When the grid voltage fluctuates, it will cause a short-term power failure or low voltage in the working coil of the electromagnetic or AC contactor, resulting in dynamic, The suction force of the static iron core is less than the elastic force of the release spring, which will further cause the DCS system to shut down or the DCS monitoring operation to be interrupted, resulting in production accidents and seriously affecting the stability of the production system
