Abstract
The invention discloses a remote power supply system and provides a complete solution. The remote power supply system is particularly convenient to supply power to buildings by telecom operation enterprises, and consists of power end equipment and power utilization end equipment, wherein the power end equipment comprises a boosting module and a current-limiting protection module, wherein the boosting module is used for boosting the DC power supply voltage from 48 V to 280 V and the current-limiting protection module is used for limiting the current; the power utilization end equipment comprises a voltage stabilization buffer module used for reducing the received power supply voltage from 280V to 48 V; a power supply output end of the power end equipment and a power supply input end of the power utilization end equipment are connected through a commercial telephone line; and the power supply transmission power can reach 1KW, and the transmission distance can reach 10KW. Due to the adoption of suspended power supply design, the remote power supply system can transmit the current through the commercial telephone line, saves cost, does not form lightning ring current during lightning stroke, cannot cause the damage to a switch power supply, cannot cause electric shock when people touch the power supply carelessly, and has the advantages of convenience and reliability, and extremely high safety. Meanwhile, the remote power supply system also can automatically detect load power; and when the load power exceeds the threshold, the power is automatically power-off, so the remote power supply system is safe and reliable.
Description
Technical field

Background technology
A large amount of enforcements along with the WLAN of telecommunications enterprise, indoor distributed system, bring loose, communication space easily to the user, but in the work progress of WLAN, indoor distributed system, to switch, AP, WLAN power amplifier and directly put/but trouble very of dried power supply of putting, because wlan system and chamber subsystem are multi-point and wide-ranging, and WLAN production and construction unit and chamber subsystem production and construction unit adhere to disparity items separately, often fight separately, respectively execute a cover, so both increase the maintenance cost of telecommunications enterprise, increased difficulty of construction again.
No matter be wlan system, or indoor distributed system, the requirement of powering is all had very big general character: the individual equipment output power is less (general≤50W; ≤ 170W); Input: alternating current 220V AC, direct current 12VDC/48VDC; Work between same building pipe well and floor; Be limited by the influence of identical power utilization environment;
For telecom operation enterprise, no matter what family WLAN, indoor distributed system production and construction unit are, final operation, safeguard it all is telecom operation enterprise self.How to set up the comprehensive power supply plan of a cover, very seem important at building.
Summary of the invention
In view of this,, the present invention proposes a kind of remote electric power system in order to address the above problem, safe and reliable, make things convenient for the building power supply of telecom operation enterprise especially.
The object of the present invention is achieved like this: remote electric power system is made of power end equipment and electricity consumption end equipment; Wherein power end equipment comprises:
Boost module is in order to be promoted to 280V with DC power supply voltage by 48V;
The current-limiting protection module is carried out current limliting to electric current;
Electricity consumption end equipment comprises:
The voltage stabilizing buffer module is reduced to 48V with the supply voltage that receives by 280V.
Further, power delivery power is 1KW, and transmission range is 10KM;
Further, described remote electric power system adopts the power supply design that suspends;
Further, the power output end of described power end equipment is connected with telephone wire by the city with the power input of electricity consumption end equipment;
Further, described power end equipment comprises that also one isolates levitation device, and described isolation levitation device is isolated power end equipment and the earth;
Further, power end equipment, electricity consumption end equipment and the transmission line between them are all isolated with the earth;
Further, also comprise the lightning protection module in power end equipment and the electricity consumption end equipment;
Further, also comprise the network management monitoring module in the described power end equipment,, when power surpasses threshold value, cut off the power supply automatically in order to detect bearing power.
Remote electric power system of the present invention, a total solution is proposed, make things convenient for the building power supply of telecom operation enterprise especially, in further technical scheme, remote electric power system adopts the power supply design that suspends, can pass through the local telephone transmission current, save cost, when thunderbolt, even if sense very strong thunder and lightning energy in the supply line, but since any link all do not have and the earth between leakage path, therefore can not form thunder and lightning circulation, can not cause Switching Power Supply to damage, the people touches power supply accidentally and also can not get an electric shock, convenient and reliable, and fail safe is high; Can also detect bearing power automatically simultaneously, when surpassing threshold value, cut off the power supply automatically, safe and reliable.
Other advantages of the present invention, target, to set forth in the following description to a certain extent with feature, and to a certain extent,, perhaps can obtain instruction from the practice of the present invention based on being conspicuous to those skilled in the art to investigating hereinafter.Target of the present invention and other advantages can be passed through following specification, claims, and the specifically noted structure realizes and obtains in the accompanying drawing.
