Embodiment 1

[0043] Example 1: Such as Figure 1-2 As shown, the present invention provides a technical solution, an on-line industrial frequency high-power UPS, including a protective shell, an input transformer is installed on the inner wall of the protective shell, the input transformer is connected to a PFC rectifier through a first filter, and the PFC rectifier is through a three-phase half bridge The inverter is connected to the second filter, and the output end of the second filter is connected to the input end of the static switch;

[0044] The output terminal of the first filter is connected in parallel with the voltage and current detector and the input terminal of the charger, the charger is connected with the DC converter through the battery pack, and the output terminal of the DC converter is connected in parallel with the input terminal of the three-phase half-bridge inverter;

[0045] The voltage and current detector is connected to the voltage and current detector, the DC conver...

Embodiment 2

[0051] Example 2: Such as image 3 As shown, the present invention provides a technical solution, an online power frequency high-power UPS operating system, including a shunt module, a charging module, an insulation monitoring unit, an operation module, a protection module, and a DC system bus detection module;

[0052] After the shunt module is mutually input by the AC power distribution unit, one of the AC inputs is selected to provide the charging module, and the charging module outputs a stable DC power supply. On the one hand, it supplements the battery for charging, and on the other hand, it provides switching output to provide normal work for the load. Current

[0053] The insulation monitoring unit can monitor the ground insulation status of the DC bus and each branch online. The centralized monitoring unit can realize the collection of operating parameters and the control and management of each unit, and can accept the monitoring of the background operator through the remot...

Abstract

The invention discloses an on-line power frequency high-power UPS and an operating system thereof, an on-line power frequency high-power UPS includes a protective shell, an input transformer is installed on the inner wall of the protective case, the input transformer is connected with a PFC rectifier through a first filter, the PFC rectifier is connected with a second filter through a three-phasehalf-bridge inverter, the output end of the second filter is mutually connected with the input end of the static switch, so that that structure of the invention is scientific and reasonable, safe andconvenient to use, through the three-phase half-bridge inverter, torrents of positive and negative phases are formed, achieving three-phase equality, voltage and current in the circuit are detected bya voltage-current detector and a current-voltage detector, so as to realize the self-protection of the line, stabilize the voltage through the input transformer, prevent the voltage fluctuation and damage the line, facilitate the voltage stability and the mutual protection of the internal components when the UPS operating system is operated at the power frequency, and prolong the service life ofthe UPS when the power frequency is operated.

Description

Technical field [0001] The invention relates to the technical field of UPS, in particular to an online industrial frequency high-power UPS and its operating system. Background technique [0002] UPS stands for uninterruptible power supply. It is a system equipment that connects the battery to the host and converts DC power into mains power through the host inverter and other module circuits. It is mainly used for single computer, computer network system or other power electronic equipment such as electromagnetic Valves, pressure transmitters, etc. provide a stable and uninterrupted power supply. When the mains input is normal, the UPS will stabilize the mains and supply it to the load for use. At this time, the UPS is an AC voltage stabilizer. It also charges the battery in the machine; when the utility power is interrupted, the UPS immediately uses the DC power of the battery to continue supplying 220V AC power to the load through the inverter switching method, so that the load ...
