Embodiment
Describe the present invention below in conjunction with drawings and the specific embodiments.
As one embodiment of the invention, electric control system as shown in Figure 1 powers to power consumption equipment 4 with main power source 5, and stand-by power supply 1 is for powering to power consumption equipment 4 when main power source 5 cannot be powered.Realize main power source 5 or stand-by power supply 1 to be connected to uninterrupted power supply 3 by distribution box 2, and then be connected to power consumption equipment 4.Distribution box 2 is arranged in when main power source 5 can be powered and is connected with uninterrupted power supply 3 by main power source 5, forms open circuit between uninterrupted power supply 3 and stand-by power supply 1; Form open circuit when main power source 5 cannot be powered by between main power source 5 and uninterrupted power supply 3, be connected between stand-by power supply 1 with uninterrupted power supply 3.Wherein, described stand-by power supply 1 can be storage battery, diesel engine generator or gasoline engine generator.Described main power source 5 can be civil power.
The concrete structure of distribution box 2 as shown in Figure 2, comprises in instant diverter switch 201, main power source contact 204 and stand-by power supply contact 205, Fig. 2 and the state that instant diverter switch 201 is not connected with main power source contact 204 or stand-by power supply contact 205 has been shown.Instant diverter switch 201 is connected with uninterrupted power supply 3, and main power source contact 204 is connected with main power source 5, and stand-by power supply contact 205 is connected with stand-by power supply 1.When main power source 5 can be powered, instant diverter switch 201 contacts with main power source contact 204, thus makes to form path between main power source 5 and uninterrupted power supply 3; When main power source 5 cannot be powered, instant diverter switch 201 automatically switches to and contacts with stand-by power supply contact 205, thus makes to form path between stand-by power supply 1 and uninterrupted power supply 3.Such as, by arranging pre-fastening moment mechanism and electromagnet in instant diverter switch 201, main power source 5 make when can be powered, electromagnet produces magnetic force and instant diverter switch 201 is linked together with main power source contact 204, when main power source 5 is without electricity, electromagnet loses magnetic force thus instant diverter switch 201 is driven under the drive of pre-fastening moment mechanism and contacts with stand-by power supply contact 205, thus realizes instant diverter switch 201 and to automatically switch power supply.
When stand-by power supply 1 is generator, in distribution box 2, also comprise the starting switch 203 of generator, instant diverter switch 201 is also provided with stand-by power supply contact 202.As shown in Figure 2, when main power source 5 cannot be powered, drive stand-by power supply contact 202 to contact with starting switch 203 downwards when instant diverter switch 201 switches, thus starter-generator starts generating, power to give power consumption equipment 4.
The concrete structure of uninterrupted power supply 3 as shown in Figure 3, comprise the rectifier 301, inverter 302 and the conversion pressurizer 303 that connect successively, respectively rectification, inversion and voltage stabilizing are carried out to the electric current flowed through, with the demand making the electric current exported from uninterrupted power supply 3 meet power consumption equipment 4.Uninterrupted power supply 3 also comprises battery pack 304, battery pack 304 is connected with inverter 302 with rectifier 301 respectively, when main power source 5 or stand-by power supply 1 are powered, electric current flows through rectifier 301, and battery pack 304 is charged, to ensure that in battery pack 304, energy storage remains in zone of reasonableness; When main power source 5 and stand-by power supply 1 all cannot be powered, battery pack 304 is outwards powered through inverter 302 and conversion pressurizer 303, to ensure that power consumption equipment 4 normally works.
Uninterrupted power supply 3 also comprises electric quantity display device 305, is connected with battery pack 304, for detecting and showing the dump energy of battery pack 304.
Uninterrupted power supply 3 also comprises warning device 306, is connected with described electric quantity display device 305, sends alarm signal when being arranged in the early warning value that described dump energy reaches default.When main power source 5 and stand-by power supply 1 cannot restore electricity for a long time, cannot power for power consumption equipment 4 for a long time because energy storage in battery pack 304 is limited, therefore early warning value is set, such as 60%, alarm signal be sent automatically to attendant when the dump energy in battery pack 304 reaches early warning value, attendant is made to show up when safeguarding power consumption equipment 4 in time also still in work, in order to avoid the situation that unexpected power-off causes device damage or loss of data occurs power consumption equipment 4.Described alarm signal can be such as note form or mail he.
Above embodiment only for illustration of technical scheme of the present invention, is not limited to protection scope of the present invention.The amendment that those skilled in the art can carry out technical scheme of the present invention or replace on an equal basis, and do not depart from the spirit and scope of technical solution of the present invention.
