System of shop - the general instructions and precautionary measures
By car the generator of alternating current is defined. At the device of the additional electric equipment you check that it was the authorities of the generator enough for power supply of this equipment.
The incentive of the generator is carried out from a ridge belt of a bent shaft of the motor.
The generator represents the three-phase synchronous electrical machine with an electromagnetic incentive. For transformation of alternating current in constantly the rectifier on diodes is installed in the generator. The effort is regulated by the installed microelectronic regulator of effort.
In operating time of the generator current which passes after an incentive parcel around poles of the motor creates magnetic current. At turn of the motor under each subzom statora it goes to the South, the North Pole of the motor and magnetic working current which goes subzy statora changes in size and effort. This variabele magnetic current creates electromotive force in a parcel of statora. klinoobrasnaja the poljusnych form of tops of the motor thus is chosen that allows to receive a form of the bent electromotive force which is close to in the form of a sine.
With a high frequency of Drehens of the motor of the generator if the effort of the generator increases as 13.6 - 14.6 In, the regulator the effort is locked also current parcels of an incentive does not go. The effort of the generator falls, the otpirajetsja regulator passes current parcels of an incentive also again. Sometime is available above than the frequency of Drehens of the motor of the generator, subjects several time of the locked condition of the regulator, falls so from this effort at the generator exit stronger. Process of Verriegelung and Aufschließens of the regulator happens with high frequency therefore fluctuations of effort at the exit of the generator are not remarkable, and they can really constantly stop, support at the height of 13.6 - 14.6 watts
The system of shop demands periodic service, however, there is no priwodnoj of belts, the battery and lines with plugs have to be served Routine maintenance of intervals is appropriately given in the head.
At the application of ignition on the control panel the control lamp which signals about an accumulator discharge has to ignite. It has to lose force after start of the motor at once. If it does not lose force or ignites during the movement, the system of shop is wrong. If the lamp at the appendix of ignition does not light up, then is burned or the lamp, its line took down or it is the generator incorrectly.
Precautionary measures in operating time with the generator Before performing some works on system of shop, it is necessary to get acquainted it is necessary with the following precautionary measures:
You never switch off the battery or the regulator of effort if the motor and the generator work.
You never close a clip of an incentive of the generator or the cable strengthened on it on weight.
You never confuse lines of the regulator of effort.
You never accept the effort regulator if it is connected with the weight (the real damage).
You never accept the generator if the battery of a contour is not switched off.
At the battery device you follow that the negative clip joined weight.
You never use the effort indicator which directly joins on the budgetary network (110/220). Use only the indicator on 12 W.
Do not check diodes of transfer of effort more than 12 V or to an outstanding knife of resistance as it has an effort too highly for diodes and they will be punched when checking (short circuit) will happen. When checking isolation of the electric leading device of an outstanding knife of resistance it is necessary to exclude all lines of the generator.
If the battery is invited in a certain condition of the charger, batteries have to be switched off to both cables. To connect a positive clip of the charger with a positive clip of the battery, and a negative clip of the charger with a negative clip of the battery.
Exclude all lines of the generator and from the accumulator at electric welding of some details of a body.
Check chains and knots of the electric equipment and remove defects at not working motor and the excluded battery.
Wrong accession of lines leads to destruction of the rectifier and regulator of effort.
