And – to the generator

The prevention

Wire fastening (In the marksman) make the moment of a tightening 15 1 Nanometer. If the moment of a tightening of a wire less demanded, that, probably, occurrence of following malfunctions:

  – Degree of gymnastics of the accumulator decreases;
  – Electric equipment work is broken;
  – As a result искрения there is a danger of ignition;
  – Pressure increase in an onboard network of the car, leading to failure of electronic blocks of management.

Dark blue wire (D ) tighten the moment 3,2 0,2 Nanometers.

6 – bolt М8х60, 25 Nanometers,
And – to the generator

In cars alternating current generators are established. Depending on model and the electric equipment established on the car generators of various capacity can be 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 клиновым 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 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, the pressure regulator 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

At generator checks, and also at car operation it is necessary to observe a number of simple rules not to put the generator out of action:

Not to suppose work of the generator with disconnected from a clip of the generator the storage battery. Without the storage battery in an onboard network of the car there are dangerous impulses перенапряже ния at switching-off of any consumers of the electric power. These pulse an overstrain can put out of action the electronic equipment of the car, including a regulator of pressure and diodes выпрямительного the generator block.

Not to check working capacity of the generator on a spark, even short-term connection плюсового a clip of the generator with weight. Thus through diodes the considerable current proceeds and they damage ся. To supervise pressure of the generator it is possible only the voltmeter.

The minus of the storage battery should incorporate always to weight of the car, and plus to be connected to a generator clip. Erroneous (return) inclusion of the battery will immediately cause passage of the raised current through generator diodes, and they will fail.

Not to check diodes pressure more than 12 In or мегометром as it has too high pressure for diodes and they at check will be punched (there will be a short circuit). At check of isolation of electroconducting мегометром it is necessary to disconnect all wires from the generator.

It is necessary to disconnect all wires from the generator and from the accumulator at electric welding of any details of a body.

To check chains and knots of an electric equipment and to eliminate malfunctions it is necessary at the idle engine and the disconnected storage battery.
