Less than performing timely.The result caused is exactly: when in main frame, the dust of deposition runs up to a certain degree, can cause heat radiation effect
The most bad, run into that there was dampness in the air also can cause host work not normal;When input power fault, energy-storage battery is negative by inverter
When carrying power supply, owing to energy-storage battery long-term work is at floating charge state, its life-span and performance can not get ensureing normally, as long as having one
Block battery failure, may result in load supplying and interrupts.Final result all will cause the impact produced, and it is passive to cause
Maintenance down.Contradiction between load power supply continuously and UPS interruption maintenance require is protruded.
Present UPS product all considers exchange auto by pass passage in the design of current supply circuit, in theory can be real
Existing double loop power supply switching, it is achieved UPS regularly interruption maintenance.Can along with the update of UPS product, the charging of UPS, inversion,
Electric discharge, bypass changeover and various protection control all to achieve intellectuality, and this intellectuality is all by micro-process of the internal configuration of UPS
Device realizes.Owing to the power supply of microprocessor and various switching equipment is all provided by UPS main frame, once UPS main frame breaks down,
Microprocessor work will be caused abnormal, make various intelligentized control method lose efficacy, thus cause UPS load supplying to interrupt.Such that
Ups power is made to provide exchange auto by pass passage, final as control to switch abnormal and affect load supplying.
Utility model content
In order to solve the above-mentioned problems in the prior art, this utility model provides a kind of beneficially UPS off-line maintenance
Switching circuit.
The technical solution adopted in the utility model is: a kind of switching circuit being beneficial to UPS off-line maintenance, including in parallel three
Branch road, three branch road tops in parallel connect with input power UPS, and wherein, the first branch road is hard maintenance bypass passage, the first branch road
In exchange manually hard maintenance bypass chopper is installed;Second branch road is exchange auto by pass passage, and the top of the second branch road is extremely
Exchange auto by pass chopper and static switch it is sequentially connected in series between end;The end of the first branch road and the end of the second branch road
Between output chopper is installed, the outfan of output chopper is power supply UPS outfan;The top of the 3rd branch road to end it
Between be sequentially connected in series lead-in circuit breaker, rectifier filter, inverter, isolating transformer, static switch;Rectifier filter and inversion
The connection line of device series connection is connected by wire with backup battery group.
Further, the hardest maintenance bypass chopper of exchange, exchange auto by pass chopper, output chopper, inlet wire
The load capacity of chopper is identical with the load capacity of input power UPS.
The beneficial effects of the utility model are: the utility model proposes the improvement that a set of simple and practical UPS powers and cut
Change circuit, solve the contradictory problems of UPS load power supply continuously and interruption maintenance, it is achieved that ups power is powered and bypass changeover;
Both solved manufacturing enterprise UPS to power continuously the contradictory problems with interruption maintenance, again economization UPS have employed hot standby, redundancy with
And the investment cost that N+1 etc. is expensive, it is achieved that the upper and lower line of ups power, it is ensured that ups power is fixed according to maintenance technique standard
Phase carries out maintenance, extends the UPS equipment life-span, reduces fault rate.

Detailed description of the invention
Below in conjunction with the accompanying drawings embodiment of the present utility model is described in detail.
A kind of switching circuit being beneficial to UPS off-line maintenance, including three branch roads in parallel, three branch road top and inputs in parallel
Power supply UPS connects, and wherein, the first branch road is hard maintenance bypass passage, is provided with the hardest maintenance bypass of exchange in the first branch road
Chopper 9;Second branch road is exchange auto by pass passage, is sequentially connected in series exchange the most other between the top of the second branch road to end
Circuit breaker 2 and static switch 7;Output chopper 10 is installed between end and the end of the second branch road of the first branch road, defeated
The outfan going out chopper 10 is power supply UPS outfan;The top of the 3rd branch road is sequentially connected in series lead-in circuit breaker between end
1, rectifier filter 3, inverter 5, isolating transformer 6, static switch 8;The connecting line that rectifier filter 3 is connected with inverter 5
Road is connected by wire with one end of backup battery group 4, the other end ground connection of backup battery group 4.
As it is shown in figure 1, after getting out the equipment such as the chopper suitable with power supply UPS load capacity and wire and material, profit
Implementing by the chance of load interruption maintenance, specific implementation process and content are as follows: carrying out on chopper 1 at original UPS
And connecing the hardest maintenance bypass chopper 9 of exchange, the outfan at original UPS installs output chopper 10 additional;Exchange auto by pass
Chopper 2, connects through inverter 5 and the outfan of static switch 8 and after connecing through outfan and the input power of static switch 7
Enter to export the input of chopper 10;The outfan of the hardest maintenance bypass chopper 9 of exchange accesses the defeated of output chopper 10
Go out end, power to the load.
In the case of UPS normal power supply, lead-in circuit breaker 1, output chopper 10 close, exchange auto by pass chopper 2, friendship
The hardest maintenance bypass chopper 9 of stream disconnects.When UPS or set of cells need off-line maintenance to safeguard, on the guidance panel of UPS
Being closed by exchange auto by pass chopper 2, UPS is switched to bypass condition, the harder maintenance bypass open circuit of manual closing exchange
Device 9, at this moment input power is by exchanging auto by pass chopper 2 and exchanging the hardest maintenance bypass chopper 9 simultaneously to load
Power supply;Disconnecting UPS the most again and export chopper 10, UPS lead-in circuit breaker 1, at this moment input power is by the hardest maintenance of exchange
Bypass breaker 9 powers to the load, and UPS and set of cells can be overhauled and safeguard by off-line.
When UPS and set of cells are overhauled and maintenance completes to need again to reach the standard grade, first close the lead-in circuit breaker 1 of UPS, make
Exchange auto by pass chopper 2 normally, is closed on the guidance panel of UPS by UPS main frame and micro-process power supply and action thereof,
UPS is switched to bypass condition, is closed again the output chopper 10 of UPS, and at this moment input power is by exchange auto by pass chopper 2
With powering load while of exchanging the hardest maintenance bypass chopper 9;Last disconnection again exchanges the hardest maintenance bypass chopper
9, start UPS by UPS guidance panel, now load by ups power normal power supply.
