Gymnastics system - the general data and security measures The general information Generator Bosch elements In the car the alternating current generator is established. At installation of the additional electric equipment check up, that capacities of the generator was enough for a food of this equipment. The generator drive is carried out by a ridge belt from a cranked shaft of the engine. The generator represents the three-phase synchronous electric car with electromagnetic excitation. For transformation of an alternating current in constant the rectifier is built in the generator on diodes. Pressure is regulated by the built in microelectronic regulator of pressure. At work of the generator the electric current proceeding on a winding of excitation, creates a magnetic stream round rotor poles. At rotor rotation under each tooth статора passes that southern northern pole of a rotor and the working magnetic stream passing through teeth статора, varies on size and pressure. This variable magnetic stream creates in a winding статора electromotive power. The klinoobraznaja form of polar tips of a rotor is picked up in such a manner that allows to receive the form of curve electromotive power close to the sinusoidal. At high frequency of rotation of a rotor of the generator when pressure of the generator becomes more than 13.6 – 14.6 In, a regulator pressure is locked also a current through a winding of excitation does not pass. Pressure of the generator falls, the regulator opens and again passes a current through an excitation winding. The above frequency of rotation of a rotor of the generator, the is more time of a closed condition of a regulator, hence, that pressure on a generator exit more strongly decreases. Process of lock-out and regulator unlocking occurs to high frequency, therefore pressure fluctuations on a generator exit are not appreciable, and it is almost possible to consider to its constants supported at level of 13.6.14.6 Century The system of gymnastics does not demand periodic service, however приводной a belt, the storage battery and wires with sockets should be served according to resulted in the Head Current leaving and service by intervals. At ignition inclusion on a control panel the control lamp signalling about a discharge of the accumulator should light up. It should die away at once after engine start. If it does not die away or lights up during movement, the gymnastics system is faulty. If the lamp is not lighted at ignition inclusion or the lamp has fused, its conducting is torn off or the generator is faulty. Security measures at work with the generator
