It is featured as converting single-phase power supply circuit to be three-phase four-wire system booster mixed power supply circuit and using branch circuit to supply power for emission unit and UPS electric power storage unit.
Description
Technical field: the present invention relates to a kind of communications transmit base station power supply device and method thereof, middle-size and small-size communications transmit base station power supply device in particularly a kind of rural area and method thereof.
Background technology: the general shared single-phase 220V power supply circuits of existing vast farmer communication transmitting base station power devices system and battery system are as the requirements of support, this single phase circuit existence is big because of the voltage loss of circuit distance, pressure drop is big and load heavy, cause frequent single-phase power failure easily, particularly outstanding for outlying mountain area especially.According to investigations, the communications transmit base station of rural area outlying mountain area majority all is based upon on the mountain top, more needs the transmission line of long distance, strengthened the kwh loss of circuit self virtually, and voltage attenuation is very serious, often causes outage or phase shortage situation to take place.At present, for the transmitting base station communication equipment that high standardization requires, then can't adapt to and satisfy the demand of normal electricity consumption.Simultaneously, because of outage and phase shortage problem often occurring, make storage battery often be in undercharge and scrapped, Huawei's 3006 transmitters for example, comprise battery system when 220 volts of voltage power supplies, electric current can reach more than 17 amperes, and so big electric current carries the above long distance of km to realize, have a strong impact on the transmitting base station normal operation like this, but the most important thing is the reputation of directly influence and infringement common carrier.
Summary of the invention: the object of the present invention is to provide a kind of electric power system of transmitting base station equipment and standby accumulating system to boost and hybrid power supply, effectively solve single-phase load overload, phase shortage and power cut problem, guarantee the middle-size and small-size communications transmit base station power supply device in rural area and the method thereof of transmitter and standby accumulating system safe operation.The present invention is achieved in that method of supplying power to of the present invention is that the single phase power supply circuit is transformed to three-phase four-wire system hybrid power supply circuit, and parallel circuit provides safety power supply for transmitter and UPS accumulating system.Electric supply installation of the present invention by civil power, two check cutter, transformer, stabilized voltage power supply, UPS accumulating system, change relay switch, transmitter and stand-by generator automatically and form.Civil power adopts three two check cuttves that are connected, and is divided into two-way by two check cuttves, and one tunnel two phase line enters transformer; Another road phase line and center line enter the UPS accumulating system, the voltage of transformer output enters automatic conversion relay switch by stabilized voltage power supply, and directly provide power supply for transmitter, the voltage of UPS accumulating system output enters automatic conversion relay switch equally, and providing back-up source for transmitter by automatic conversion relay switch, two check cuttves also are connected with stand-by generator and form.
Description of drawings: Fig. 1 is circuit theory diagrams of the present invention, and Fig. 2 is a circuit block diagram of the present invention.
Execution mode: as shown in Figure 1, 2, method of supplying power to of the present invention is that the single phase power supply circuit is transformed to three-phase four-wire system hybrid power supply circuit, and parallel circuit provides safety power supply for transmitter and UPS accumulating system.Electric supply installation of the present invention by civil power (1), two check cutter (2), transformer (3), stabilized voltage power supply (4), UPS accumulating system (5), change relay switch (6), transmitter (7) and stand-by generator (8) automatically and form.Civil power (1) adopts three-phase four-wire system to connect two check cuttves (2), the contact A of civil power (1), B, C, N is connected to a of two check cuttves (2), b, c, the n contact, and be divided into two-way by two check cuttves (2), one tunnel two phase line 380V inserts transformer (3), another road phase line and center line 220V insert UPS accumulating system (5), transformer (3) output voltage is 220V, and by the automatic conversion of stabilized voltage power supply (4) access relay switch (6), directly provide power supply for transmitter (7), UPS accumulating system (5) output voltage also is 220V, and the same conversion relay switch (6) automatically that inserts, and provide back-up source for transmitter (7) by changing relay switch (6) automatically, two check cuttves (2) also are connected with stand-by generator (8), stand-by generator (8) is provided with F, H, S, four contacts of E are respectively with the f of two check cuttves (2), h, s, e connects.
When the civil power three-phase four-line system entered transformer by two check cutter one tunnel two phase line 380V, output voltage was 220V, and directly by stabilized voltage power supply and automatic conversion relay switch, sent into transmitter; Another road phase line and the center line 220V of three-phase four-line system by two check cuttves then enters the UPS accumulating system and charges, and as the back-up source of transmitter; When civil power cut off the power supply, the inversion system of UPS accumulating system started automatically, and at this moment civil power just cuts off automatically, and the back-up source of UPS accumulating system provides 220V AC power by changing relay switch automatically to transmitter; After civil power changed normal power supply over to, back-up source automaticallyed switch, and the UPS accumulating system is stopped power supply, and civil power continues as transmitter power supply is provided, and at this moment the UPS accumulating system just keeps charged state; When civil power cuts off the power supply for a long time,, just can substitute civil power and finish power supply task into transmitter and UPS accumulating system as long as start stand-by generator.
Advantage of the present invention is with former communications transmit base station equipment and the shared single phase power supply circuit of accumulating system, be transformed to the three-phase four-wire system hybrid power supply circuit that boosts, effectively solve single-phase load overload, phase shortage and power cut problem, guaranteed the safe operation of transmitting base station equipment and accumulating system, the more important thing is the useful life that has prolonged accumulating system, can be because of often power failure or circuit phase shortage influence the reputation of common carrier.
