Abstract
The invention relates to a building weak current power supply system, in particular to an independent intelligent building weak current power supply system. A mains supply power distribution cabinet is connected with and supplies power to an uninterruptible power supply (UPS). The UPS is connected with and supplies power to a switch cabinet. The switch cabinet is connected with multiple switch boxes. The switch boxes are connected with and supplies power to machine room devices and site devices respectively. The independent intelligent building weak current power supply system can be used in emergency, and the situation that the voltage shock caused by sudden outage influences the normal operation of the devices, so that weak current device elements are damaged can be avoided; by the adoption of the independent intelligent building weak current power supply system, power source pollution such as a surge on the mains supply, an instant high voltage, an instant low voltage, wire noise and frequency deviation can also be eliminated, the quality of a power source is improved, and the high-quality power source is provided for a weak current system.
Description
Technical field
The present invention relates to building light current electric power system, especially a kind of weak current of intelligent building autonomous power supply system.
Background technology
In the design of weak current of intelligent building system, equipment power-extracting mostly adopts the mode of getting civil power nearby to power, and this power taking is nearby difficult to the power supply quality ensureing weak current equipment.Now a large amount of microelectronic devices is applied and is networked in weak electricity system, the integrated level of its components and parts is more and more high, information storage is more and more large, speed and precision improve constantly, operating voltage only has a few volt, information current only has microampere order, thus disturb extremely responsive to external world, relative with superpotential ability to bear fragile to electromagnetic pulse, when equipment overvoltage and electromagnetic field intensity reach a certain threshold values, light then cause system down, such as: malfunction, information dropout, characteristic deteriorate, fluctuation of service etc., heavy then cause whole equipment or its components and parts permanent damage.
Summary of the invention
For solving the problem, the invention provides a kind of reliable and stable weak current of intelligent building autonomous power supply system.
The technical solution used in the present invention is:
A kind of weak current of intelligent building autonomous power supply system, civil power power distribution cabinet connects power supply to uninterrupted power supply UPS, described uninterrupted power supply UPS connects power supply to switch cubicle, and described switch cubicle connects multiple switch-box, and described switch-box connects power supply respectively to calculator room equipment and field apparatus.
In described civil power power distribution cabinet, master switch is provided with 24V shunted exciter tripping element.
At the reserved road ups power socket of the annex of switch cubicle, a reserved road socket in switch cubicle, civil power power distribution cabinet, uninterrupted power supply UPS are all placed on machine room power distribution station.
When field apparatus distance center machine room is far away, adopts on-the-spot UPS direct feeding system, install a set of UPS at the scene additional, then power to switch electricity cabinet by on-the-spot UPS, switch electricity cabinet is powered to multiple switch-box again, and switch-box is powered to field apparatus.
Compared with prior art, the invention has the beneficial effects as follows:
Weak current of intelligent building autonomous power supply system can do Emergency use, and the voltge surge preventing unexpected power-off from bringing affects equipment and normally runs, and causes damage to weak current equipment element; The surge on civil power, instant high-voltage, instantaneously low-voltage, electric wire noise and frequency shift (FS) etc. " power pollution " can be eliminated simultaneously, improve power quality, for weak electricity system provides high-quality power supply.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention 1;
Fig. 2 is the structural representation of the embodiment of the present invention 2;
In figure: civil power power distribution cabinet 1, uninterrupted power supply UPS 2, switch cubicle 3, switch-box 4, calculator room equipment 5, field apparatus 6.
Embodiment
To illustrate below in conjunction with accompanying drawing and embodiment describes the present invention in detail.
Embodiment 1:
As shown in Figure 1, weak current of intelligent building autonomous power supply system, in civil power power distribution cabinet 1, master switch is provided with 24V shunted exciter tripping element, after civil power power distribution cabinet 1 cuts off mains supply by civil power power distribution cabinet 1 bypass power supply to uninterrupted power supply UPS 2, uninterrupted power supply UPS 2 powers to switch cubicle 3, switch cubicle 3 connects multiple switch-box 4, and switch-box 4 is powered respectively to calculator room equipment 5 and field apparatus 6.
Embodiment 2:
When field apparatus distance center machine room is far away, adopt on-the-spot UPS direct feeding system, as shown in Figure 2, connect uninterrupted power supply UPS 2 respectively and secondary uninterrupted power supply UPS 21, uninterrupted power supply UPS 2 power to switch cubicle 3 in the bypass of civil power electricity cabinet 1, switch cubicle 3 connects multiple switch-box 4, switch-box 4 is powered to calculator room equipment 5, secondary uninterrupted power supply UPS 21 powers to auxiliary switch cabinet 31, and auxiliary switch cabinet 31 connects multiple auxiliary switch case 41, and auxiliary switch case 41 is powered to field apparatus 61.
At switch cubicle 3 and the reserved road ups power socket of auxiliary switch cabinet 31 annex, reserve a road socket in switch cubicle 3 and auxiliary switch cabinet 31, civil power power distribution cabinet 1, uninterrupted power supply UPS2 and secondary uninterrupted power supply UPS 21 are all placed on machine room power distribution station.
For ensureing power supply high-quality, UPS selects inversion preferential.
Adopt at Emergency use after above-mentioned two schemes, the voltge surge that can prevent unexpected power-off from bringing affects equipment and normally runs, and causes damage to weak current equipment element; Eliminate the surge on civil power, instant high-voltage, instantaneously low-voltage, electric wire noise and frequency shift (FS) etc. " power pollution " simultaneously, improve power quality, for weak electricity system provides high-quality power supply.
