Description
Technical field
The utility model relates to a kind of power supply changeover device, a kind of automobile power source transducer of more specifically saying so.
Background technology
At the characteristics and the requirement of the transregional maneuver warfare of field army, on leader's command car, want allocating radio and notebook computer, to finish the task such as in good time commander, transfer of data and satellite fix in motor-driven.Give the power supply of the radio station on leader's command car in the past, mainly contained following three kinds of modes: 1, on command car, install the 28V generator special additional; 2, carry big capacity storage battery; 3, carry small-sized alternating current generator.The deficiency of first kind of mode is the structure that will change automobile engine, complex process, cost height; The deficiency of the second way is the restriction that is subjected to the storage battery capacity, can not work long hours, and is difficult for again storage battery is charged in motor-driven; The deficiency of the third mode is the smoke evacuation system that alternating current generator is not set on leader's command car, is difficult for using in motor-driven.
Summary of the invention
The purpose of this utility model provides the not only reliable and stable but also simple automobile power source transducer that is suitable for of a kind of radio station power supply on leader's command car.
In order to realize above-mentioned purpose, the automobile power source transducer that is provided, its design feature is to comprise isolating transformer, the primary coil of this isolating transformer is connected with the output of automobile current generator, on the secondary coil of isolating transformer, be connected to rectifier, the output of rectifier is connected to filter, and the output of filter is the positive output end of automobile power source transducer, the negative output terminal ground connection of automobile power source transducer.
In order to improve rectification effect, above-mentioned rectifier is a bridge rectifier, also can be the rectifier of other form.
In order to make filter have pressure stabilization function concurrently, above-mentioned filter is the storage battery group of 28V.
Output voltage for energy display automobile power supply changeover device is parallel with voltmeter at the two ends of filter.
In order to show load current, be in series with ammeter at the output of rectifier.
The operation principle of automobile power source transducer provided by the utility model is: the alternating current of the 12V that automobile current generator sent, boost to 24V through isolating transformer, after rectifier rectification, the filtering of storage battery group and voltage stabilizing, become stable direct current 28V again, to the stable power supply in radio station.As long as the engine operation on the command car, automobile current generator is generating just, is not subjected to the restriction of storage battery capacity, accomplishes that the moving electricity of car has, the car leakage of electricity is walked, car has a power failure foot, for " communication in moving " provides reliable power supply guarantee.
Learn automobile power source transducer provided by the utility model, the radio station power supply on leader's command car, not only reliable and stable but also simple being suitable for by above narration.Can also export the voltage of different numerical value, to other power devices by changing the no-load voltage ratio of isolating transformer.
