The maintenance of auto load booster

The auto load booster in the course of the general use of the cover is not allowed to remove the cover, the normal situation is about 200 hours per work to conduct a comprehensive inspection and maintenance, its contents are as follows:

Remove the cover and check the contact surface for dirt and burn. If there is dirt, you can use a cleaner paper to wipe the contact surface. If the contact occurs ablation or flat and lead to poor contact, generally with "00" sandpaper or sand to polish, and finally wipe with clean paper.

Check the firmness of each connector, measure the resistance and the resistance of each coil. If damaged, repair or replace new parts in time.

Check the closing voltage and reverse current of the interrupter, the limit voltage of the voltage regulator, the current limit of the restrictor, and the clearance and air gap of the various contacts. If not meet the requirements, should be adjusted.

4 Check the adjusted regulator. When starting the diesel engine, observe the indication of the charging ammeter. If the diesel engine is running at medium speed or higher, the ammeter pointer still points. "-" side, which means that the contact of the circuit breaker is not disconnected, should quickly disconnect the ground switch; otherwise, will damage the battery, adjusters and charging generators, etc. If the diesel engine starts to rated speed after the ammeter pointer still " 0 ", the adjustment is not adjusted according to technical requirements, should be re-check and adjust.

The reasons: high voltage auto load booster with a higher requirements

The high voltage auto load booster generally on the working environment requirements are higher, mainly because the device's integrated circuit requires a better working environment, easy to damage; carbon brush speed is slow, the need to start the instantaneous high pressure can not meet the start requirements; The cost is slightly higher than the product, the mission life is short, the maintenance cost is higher, this product can solve the instantaneous high pressure start, the purchase cost and the maintenance cost are lower, and the installation is simple and the use environment is not high, the volume is small, is convenient for the flow operation.

Application of the automatic voltage booster

1.It controls the voltage of the system and has the operation of the machine nearer to the steady state stability.

2.It divides the reactive load between the alternators operating in parallel.

3.The automatic voltage booster reduce the overvoltages which occur because of the sudden loss of load on the system.

4.It increases the excitation of the system under fault conditions so that the maximum synchronising power exists at the time of clearance of the fault.

When there is a sudden change in load in the alternator, there should be a change in the excitation system to provide the same voltage under the new load condition. This can be done by the help of the automatic voltage regulator. The automatic voltage regulator equipment operates in the exciter field and changes the exciter output voltage, and the field current. During the violent fluctuation, the ARV does not give a quick response.

For getting the quick response, the quick acting voltage regulators based on the overshooting the mark principle are used. In overshoot mark principle, when the load increase the excitation of the system also increase. Before the voltage increase to the value corresponding to the increased excitation, the regulator reduces the excitation of the proper value.

Working principle of automatic voltage booster

Oil-immersed high-pressure test transformer, also known as YDJ (G) AC test transformer, TDM (G) AC-DC dual-use automatic voltage booster using high-quality cold-rolled silicon steel sheet stacked from. The coil is a concentric pagoda-shaped multi-layer cylinder, low voltage coil, high voltage coil outside; shell for portable, with small size, light weight, beautiful appearance, easy to move and so on.With the power frequency 220V (10KVA above with 380V) power access control box (Taiwan) (for the test transformer supporting equipment, see the details of the control box (Taiwan) manual), the auto-regulator regulator 0-220V / 380V Voltage input to 100kva oil transformer primary winding According to the principle of electromagnetic induction, in the secondary (high voltage) winding according to its ratio with the primary winding turns to obtain the same multiple of the voltage amplitude. - Power frequency high voltage This high frequency of high voltage silicon reactor rectifier and capacitor filter can be obtained DC high voltage, which amplitude is the power frequency high voltage effective value times. Oil-immersed high-pressure test transformers are divided into three categories: AC type named YDJ (G), AC and DC type named TDM (G), and can be with 200V tap YDJ (G), TDM (G) Connected to a string test transformer.

Two types of high voltage auto load booster

step voltage regulators applied in the utility’s distribution systems are generally medium-voltage mechanical automatic voltage regulators (AVR). It should be noted that there are two distinct types of high voltage auto load booster: Medium-voltage (mechanical) and the Low-voltage regulators (mechanical or electronic). The difference in their operation and design clearly demonstrate that their applications are not the same. The latter is intended to protect end-user devices from overvoltage and undervoltage conditions.
