The concrete structure of the utility model is provided by following accompanying drawing and embodiment:
Fig. 1 is three grades of insurance communication base station electric power system circuit theory diagrams.
Five, embodiment:
The utility model does not receive the restriction of following embodiment, can confirm concrete execution mode according to the technical scheme and the actual conditions of the utility model.
Embodiment: as shown in Figure 1, three grades of insurance communication base station electric power systems are by three power supply sources independently, and control power supply source work whether system controller, and transformation, rectification, pressure stabilizing device, and breaker of plastic casing, inverter are formed.Transformation, rectification, pressure stabilizing device, breaker of plastic casing, inverter are the market purchasing part, are prior art, do not do detailed description at this.
Three independently power supply source adopt grid alternating current source, direct current electric generator using fuel battery power supply respectively, exchange the diesel engine generator power supply, three power supply sources be parallelly connected.
The power output end of grid alternating current source, interchange diesel engine generator power supply is divided into two-way; One the tunnel is connected with system controller; Be connected with transformation, current stabilization, rectifying installation therebetween, this road utilizes transformation, current stabilization, rectifying installation output to be fit to the voltage that system controller uses, and is its power supply; Another road is connected with breaker of plastic casing; And be connected with system controller, output AC electricity behind the breaker of plastic casing, and be divided into two-way; One the tunnel directly is connected with AC load; Another road connects transformation, rectification, pressure stabilizing device, and output is fit to the DC power supply that communication equipment uses, and the DC power supply that is suitably for charge in batteries.
The power output end of direct current electric generator using fuel battery power supply is divided into three the tunnel; One the tunnel connects pressurizer is connected with system controller again, and another road connects breaker of plastic casing, and is connected with system controller; Connect AC load behind the breaker of plastic casing simultaneously; Like illumination, air-conditioning etc., also have one the tunnel directly to be connected, like communication equipment, storage battery with DC load.
Simultaneously storage battery is connected with communication equipment, direct current electric generator using fuel battery power supply respectively, is the communication equipment power supply when being respectively applied for power source conversion, and when being the direct current machine startup of direct current electric generator using fuel battery power supply, starting current is provided.
The main control chip of system controller is the P87C591 single-chip microcomputer, is externally connected with at main control chip to show and button part, current detection section, phase shortage test section, communication interface part, test section, the position of the switch, driving circuit section.Current detection section and phase shortage test section are in order to detect the working condition of three power supply sources; Show the working condition that shows three power supply sources with the button part with the form of LED lamp; Communication interface partly connects monitor network, at any time three power supply source monitor messages is published to Surveillance center through monitor network; The power supply type that current operate as normal is detected in test section, the position of the switch is grid alternating current source, direct current electric generator using fuel battery power supply, interchange diesel engine generator power supply.Driving circuit section will be sent drive signal to exchanging diesel engine generator power supply or direct current electric generator using fuel battery power supply, to start diesel engine generator or electric generator using fuel battery.
Breaker of plastic casing is used to break off or closed power supply is connected with circuit between the power consumption equipment, and this breaker of plastic casing is controlled by the drive circuit of system controller.
During use; Have in the grid alternating current source under the situation of electricity; The current detection section of system controller detects after the power supply signal; Show the operating state in grid alternating current source by the display part of system controller, and open the breaker of plastic casing in grid alternating current source by drive circuit, be illumination, air-conditioning, communication equipment, storage battery power supply by the grid alternating current source this moment.
Under the situation of grid alternating current source power failure, after system controller detects power cut signal through current detection section, show grid alternating current source power cut signal in the display part, and produce alarm signal.According in advance program setting in the system controller, direct current electric generator using fuel battery power supply is at first launched after having a power failure in the grid alternating current source.The drive circuit of system controller sends enabling signal to direct current electric generator using fuel battery power supply, and opens the breaker of plastic casing of direct current electric generator using fuel battery power supply, and be power devices by direct current electric generator using fuel battery power supply this moment.
Fuel at direct current electric generator using fuel battery power supply is used up, and the grid alternating current source also not the incoming call situation under, system controller receives the signal that runs out of gas from direct current electric generator using fuel battery power supply.The drive circuit of system controller sends enabling signal for exchanging the diesel engine generator power supply; And be that direct current electric generator using fuel battery power supply sends off signal; Open the breaker of plastic casing that exchanges the diesel engine generator power supply simultaneously, be power devices by exchanging the diesel engine generator power supply this moment.
As in direct current electric generator using fuel battery power supply or the power supply of interchange diesel engine generator power supply; Grid alternating current source incoming call; The drive circuit of system controller will or exchange the diesel engine generator power supply for direct current electric generator using fuel battery power supply and send off signal; And close direct current electric generator using fuel battery power supply or exchange the breaker of plastic casing of diesel engine generator power supply, with the breaker of plastic casing of opening the grid alternating current source, supply power by the grid alternating current source.In like manner when exchanging the power supply of diesel engine generator power supply; After direct current electric generator using fuel battery power supply is filled it up with fuel; System controller detects fuel fill it up with signal after; The device drive circuit will send off signal for exchanging the diesel engine generator power supply, and close the breaker of plastic casing that exchanges the diesel engine generator power supply, and opening direct current electric generator using fuel battery power supply simultaneously is power devices.
Synchronization has only one road power supply in running order, and each road power supply all will produce alternating current and direct current.Alternating current is alternating-current installation/AC installation power supplies such as illumination, air-conditioning; Direct current is the communication equipment power supply; Direct current is the less relatively lead acid battery charge of a pool-size simultaneously; Keep the uninterrupted power supply of communication equipment in conversion, fuel cell power generation and the diesel generation transfer process to guarantee that fuel cell power generation and grid alternating current are supplied power, and drive current is provided for fuel cell start-up.
Above technical characterictic has constituted the most preferred embodiment of the utility model, and it has stronger adaptability and best implementation result, can increase and decrease inessential technical characterictic according to actual needs, satisfies the needs of different situations.
