Example Embodiment

[0017] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0018] In order to make it easier to understand the present invention, specific examples are used to describe the implementation of the present invention in detail below.

[0019] Such as figure 1 , figure 2 As shown, a new type of industrial frequency inverter power supply with a combined structure of the present invention is characterized in that it mainly includes a standard cabinet unit 6 whose inner bottom layer is installed; input and output transformer units 5. The upper layer of the input and output transformer unit 5 includes: AC output filter, inverter, bypass output, and electronic static transfer switch unit 4. The upper layer of the AC output filtering, inverter, bypass output, and conversion electronic static switch unit 4 includes an inverter and a drive system unit 3. The upper layer of the inverter and drive system unit 3 has; the w...

Abstract

The invention relates to a novel power frequency inverter power supply in a combined-type structure. The novel power frequency inverter power supply mainly comprises a standard cabinet unit. An input/ output transformer unit is arranged on the bottom layer in the standard cabinet unit; an AC output filtering, inversion, bypass output and electronic static transfer switch unit is arranged on the upper layer of the input/ output transformer unit; an inverter driving system unit is arranged on the upper layer of the AC output filtering, inversion, bypass output and electronic static transfer switch unit; an overall machine control, display and monitoring circuit system unit is arranged on the upper layer of the inverter driving system unit; and a commercial power AC input rectification charging unit is arranged on the upper layer of the overall machine control, display and monitoring circuit system unit. The advantages are that 1) the detachable parts are arranged in the same standard cabinet, and thereby facilitating assembly; 2) fault units can be replaced quickly, thereby saving maintenance time; 3) replacement of the whole machine is prevented, thereby saving cost; 4) the units can be carried and installed detachably; 5) the units are especially suitable for standard cabinet size installation in a machine room; and 6) standard match production of each independent unit is realized conveniently.

Description

Technical field [0001] The present invention relates to a power frequency inverter power supply, which is precisely a new type of power frequency inverter power supply with a combined structure. It is mainly used for power supply; single input single output, three input three output, three input single output, industrial The manufacturing of power supply products of various specifications and capacity models of uninterruptible power supplies. Background technique [0002] At present, the existing power frequency online uninterruptible power supply is composed of input rectifier, inverter, control and display circuit, isolated output transformer (and mains input transformer), AC output filter circuit and electronic conversion output switch circuit. These are all installed in a cabinet to form an integral uninterruptible power supply. The model with this assembly structure has the following disadvantages: 1. The whole machine needs to be transported, installed, and debugged, and th...
