Charge system - the general data and security measures On considered cars the alternating current generator is used. At installation of an additional electric equipment check up, that capacities of the generator was enough for maintenance of new consumers with the electric power. The generator drive is carried out клиновидным by a 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 generator it is built in диодный the rectifier. Adjustment of target pressure is carried out by the built in regulator. At work of the generator the electric current proceeding on a winding of excitation, creates a magnetic stream round rotor poles. At rotor rotation there is a periodic change of its magnetic poles under each tooth статора, as a result, the magnetic stream passing through teeth, continuously changes on size and pressure. This variable magnetic stream creates in a winding статора electromotive power (ЭДС). The klinoobraznaja form of polar tips of a rotor is picked up in such a manner that allows to receive close to sinusoidal the form of curve ЭДС. At high frequency of rotation of a rotor when target pressure of the generator starts to exceed 13.6 - 14.6 In, the pressure regulator is locked, and the current through a winding of excitation does not pass. When pressure decreases, the regulator opens again, providing freedom пропускания a current through an excitation winding. The above frequency of rotation of a rotor, the longer a regulator remains locked and, that accordingly pressure on a generator exit more strongly decreases. Process of lock-out and regulator unlocking occurs to high frequency, therefore target fluctuations remain almost imperceptible and it is possible to consider pressure of the generator to the constants supported at level 13.6 - 14.6 Century The system of gymnastics does not demand periodic service, however check of a condition and replacement приводного a belt of the generator, the storage battery and its electroconducting it is necessary to make on a regular basis according to the schedule THAT (see the Head of Adjustment and car routine maintenance). At ignition inclusion on a combination of devices should light up quickly К/Л a charge (Controls and operation receptions see the Head). If the lamp is not disconnected after start of the engine or lights up in the course of functioning of the last, check up a condition of components of system of a charge. Refusal of activation of a lamp at ignition inclusion testifies to its exit out of operation, damage of corresponding electroconducting, or infringement of serviceability of functioning of the generator (including breakage приводного a belt).
