Summary of the invention
The object of the present invention is to provide a kind of industrial uninterrupted power supply, to solve problems such as reliability that prior art exists is low.
In order to address the above problem; Industrial uninterrupted power supply provided by the invention comprises bypath system first mainframe identical with structure, second mainframe; Said bypath system is connected with said first mainframe, said second mainframe, and said bypath system is identical with the syndeton of said first mainframe, said second mainframe; Be provided with the filter, the first input isolating transformer, pulse rectifier, inverter, contravariant transformer, first static switch that connect successively in said first mainframe; Also be provided with second static switch in said first mainframe; The output of said second static switch is connected with the output of said first static switch; The node of said pulse rectifier and said inverter is connected with the negative electrode of a check diode, and the anode of said check diode is connected with an anti-end of irritating noise elimination inductance; Said bypath system comprises second input isolating transformer and the pressurizer that connects successively, and the output of said pressurizer all is connected with the output of said first static switch of said first mainframe, the input of said second static switch; Wherein, the output of the output of said first static switch of the output of the output of said first static switch of said first mainframe, said second static switch and said second mainframe, said second static switch links together as the output of said industrial uninterrupted power supply.
According to a kind of preferred implementation of above-mentioned industrial uninterrupted power supply, wherein, said filter comprises and connects electromagnetic interface filter and THD filter successively.
By on can know, the present invention includes first mainframe, second mainframe, can realize parallel operation function/working power double copies; Improve the operational reliability of equipment to a greater extent; Especially the product that guarantees fault can not cause the paralysis of system, and in addition, the present invention also has multiple advantages.
Description of drawings
Fig. 1 is the theory structure block diagram of the preferred embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is explained further details.
Fig. 1 schematically shows the theory structure of the preferred embodiment of the present invention; As shown in Figure 1; This preferred embodiment comprises that the structure of first mainframe 1, second mainframe 2 and bypath system 6, the first mainframes 1, second mainframe 2 is identical, the two and ancillary equipment; For example bypath system 6 is eliminated inductance with the anti-noise of irritating, connecting circuit also identical.
Because first mainframe 1, second mainframe 2 are identical, in order not produce the sense of giving unnecessary details, only first mainframe 1 are elaborated below.
Be provided with EMI (the Electro Magnetic Interference that connects successively in first mainframe 1; Electromagnetic interference) filter 11, THD (total harmonic distortion, total harmonic distortion) filter 12, input isolating transformer 13, pulse rectifier 14, inverter 15, contravariant transformer 16, static switch 17.In addition; Also be provided with static switch 18 in first mainframe 1; The output of static switch 18 is connected with the output of static switch 17; The node of pulse rectifier 14 and inverter 15 is connected with the negative electrode of check diode 19, and the anode of check diode 19 is connected with an anti-end of irritating noise elimination inductance 7.Wherein, the input of electromagnetic interface filter 11 is provided with terminal 4, and terminal 4 is used for directly importing civil power.The anti-other end of irritating noise elimination inductance 7 is provided with terminal 5, and terminal 5 is used for directly being connected with the 220V direct current cabinet.
This preferred embodiment comprises bypath system and two mainframes, and two mainframes include rectifier and inverter.For pulse rectifier 14, the input of three-phase forceful electric power obtains stable dc power supply through controllable silicon pulse control, and reaches the slow effect that opens of power.General direct voltage is in 200V ± 25% scope.For inverter 15, electricity or power failure are arranged, inverter 15 all can DSP the SPWM technology of control be responsible for changing DC power supply into AC power, reach the purpose of sinewave output.Bypath system 6 is used in the inversion fault, comprises two major parts: the input isolating transformer, do isolation to forceful electric power and load.Utilize AC voltage regulator (AVR) stable within the specific limits, reliable and secure with proof load bypass supply.
