Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] figure 1 Schematically shows the principle structure of the preferred embodiment of the present invention, as figure 1 As shown, this preferred embodiment includes a first main cabinet 1, a second main cabinet 2 and a bypass system 6. The first main cabinet 1 and the second main cabinet 2 have the same structure, and the two are connected with peripheral equipment, such as a bypass system 6 and the anti-noise elimination inductance, the connection circuit is the same.

[0015] Since the first main cabinet 1 and the second main cabinet 2 are the same, only the first main cabinet 1 will be described in detail below in order not to create redundant descriptions.

[0016] The first main cabinet 1 is provided with an EMI (Electro Magnetic Interference, electromagnetic interference) filter 11, a THD (total harmonic distortion, tota...

Abstract

An industrial uninterruptible power supply comprises a bypass system, and a first mainframe and a second mainframe identical in structure, wherein a filter, a first input isolation transformer, a pulsed rectifier, an inverter, an inverter transformer and a first static switch, which are connected with each other in sequence, are arranged in the first mainframe; a second static switch is also arranged in the first mainframe; the output end of the first static switch is connected with the output end of the first static switch; the nodes of the pulsed rectifier and the inverter are connected with the cathode of a blocking diode; the anode of the blocking diode is connected with one end of a reflected noise eliminating inductor; the bypass system includes a second input isolation transformer and a voltage stabilizer connected with each other in sequence; and the output end of the voltage stabilizer is connected with the output end of the first static switch, and with the input end of the second static switch. The industrial uninterruptible power supply provided by the invention has at least one advantage to improve the running reliability of equipment.

Description

[0001] technical field [0002] The present invention relates to a UPS (Uninterruptible Power System), in particular to an uninterruptible power supply including two main cabinets suitable for the industrial field. [0003] Background technique [0004] UPS is a constant voltage and constant frequency uninterruptible power supply with energy storage device and inverter as the main component. It is mainly used to provide uninterrupted power supply to a single computer, computer network system or other power electronic equipment. When the mains input is normal, the UPS will stabilize the mains and supply it to the load. At this time, the UPS is an AC mains voltage stabilizer, and it also charges the battery inside the machine; when the mains is interrupted (accident power failure) At this time, the UPS will continue to supply 220V AC power to the load through the method of inverting the electric energy of the internal battery immediately, so as to maintain the normal operati...
