To achieve the above object, the utility model provides the following technical solutions：A kind of ups system, including breaker, isolation
Transformer, rectifier, inverter, static switch module, check diode, the breaker include bypass input breaker, master
Alternating current inputs breaker, and there are two the isolating transformers, wherein the bypass input breaker is connected to static switch
Module, the main alternating current input breaker, isolating transformer, rectifier, inverter, isolating transformer, static switch module
It is sequentially connected.
Preferably, the breaker can also include exchange output breaker, and the exchange export breaker with it is quiet
State switchs module connection.
Preferably, the breaker can also include maintenance bypass breaker, and maintenance bypass breaker both ends
It is separately connected bypass input breaker and exchanges output breaker.
Compared with prior art, the beneficial effects of the utility model are as follows：This ups system of the utility model is a kind of advanced
The super online sine wave uninterruptible power system of isolation of technical grade, it can provide reliable, high-quality, pure for precision equipment
AC power；It has the extremely extensive scope of application, all from computer equipment, electric power, communication system to industrial automation equipment
It can use；Due to super isolation design, it can not only solve the problems, such as caused by low-quality AC power, effectively eliminate leakage ground electricity

Specific implementation mode：
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.
According to Fig. 1, a kind of ups system, including breaker, isolating transformer, rectifier, inverter, static switch module,
Check diode, breaker include bypass input breaker, main alternating current input breaker, and there are two isolating transformers, wherein institute
The bypass input breaker stated is connected to static switch module, main alternating current input breaker, isolating transformer, rectifier, inversion
Device, isolating transformer, static switch module are sequentially connected, and breaker can also include exchange output breaker, and exchange output
Breaker is connect with static switch module；Breaker can also include maintenance bypass breaker, and maintenance bypass breaker both ends
It is separately connected bypass input breaker and exchanges output breaker.
The operational mode of the utility model：
1, normal operation mode
According to fig. 2, AC power is converted to DC power supply and exported to inverter by rectifier, then is converted and struck a bargain by inverter
The output of galvanic electricity source is used for load, and when AC power is converted to DC power supply, UPS inputs isolating transformer, rectifying and wave-filtering
Device and various protective devices will eliminate abnormal surging in alternating current, noise interference and since frequency shakiness or voltage fluctuation etc. are various
Influence caused by factor exports so that it is guaranteed that inverter is capable of providing stable and clean power supply to load.
2, bypass power supply pattern
According to fig. 3, when inverter is in abnormal situation, such as inverter do not open, excess temperature, short circuit, output voltage are different
Often or load is beyond inverter tolerance range etc., and inverter will be automatically stopped operation with anti-tamper, and static switch is by handing at this time
Galvanic electricity source is used through bypass output to load.
3, maintenance bypass pattern
According to Fig. 4, for there is the apolegamy maintenance bypass system type can be by UPS when UPS equipment need to carry out maintenance, repair
It switches to operation under " maintenance bypass pattern " and can guarantee that UPS equipment still supplies the lasting, stable of load in maintenance, repair
Electricity.
Embodiment provided above is the better embodiment of the utility model, only is used for facilitating illustrating the utility model, and
It is non-to impose any limitation on the present invention, any those of ordinary skill in the art, if not departing from
In the range of the carried technical characteristic of the utility model, locally changes or repair using made by the utility model disclosed technology content
The equivalent embodiment of decorations, and without departing from the technical characteristics of the utility model content, still fall within the utility model technical characteristic
In the range of.
