    After the transformer is put into capacitance compensation, only the current between the factory distribution cabinet and the high-voltage power supply line will be reduced, but the current between the distribution cabinet and the factory electrical appliances will not be reduced.

    When there is no capacitance compensation, the factory (electric motor, welding machine.

    The reactive current is flowed from the power plant (including substations at all levels) to the motor, and the current flow must occupy the [capacity resources] between the power plant and the motor, so that the line load capacity is reduced, and the [reactive current] produces [active loss] on the remote transmission line between the generator and the factory, in order to avoid a series of losses such as generator-substation-high-voltage line, the power department stipulates that the user transformer must be put into the capacitance compensation cabinet.

    The reactive current of the plant is absorbed between the distribution cabinet and the motor with a capacitor.

    In summary, it can be seen that the output current of the transformer will be reduced, but the current between the capacitor cabinet and the consumer will not be reduced.

    Transformers, after capacitance compensation, the transformer output current will be reduced, but not in the way you understand.

    The compensation capacitance of the transformer is the power factor;

    Increasing the power factor can reduce the reactive power.

    Reactive power is a kind of power consumed by the current that flows repeatedly in the ** circuit caused by the electrical characteristics of the electrical appliance but does not drive the electrical appliance and does not pass through the ammeter. The reactive current does not drive electrical appliances, but it can heat up the line, increase the burden on the transformer, and ...... the action of the protection circuit. So it's a harmful current.

    This current hazard can be reduced by applying capacitance compensation.

    Investing in capacitance compensation will reduce the output of the transformer's reactive current, which can improve the efficiency of the transformer.

    Let's talk about it briefly. For example, the full-load output current is 2300A, in fact, the active current only accounts for part of it, and the other part is the reactive current, and the active power output of the transformer cannot reach 1600kW, which may only be 1200kW. After the capacitor is put in, the reactive current can be reduced, and the active power output of the transformer remains unchanged, which is still 1200kW, but the output current may be reduced to 2000A, and the transformer can carry more loads, and the efficiency is improved.

    Dear, hello, according to the description of your question, the assistant will answer the following for you: 1. If the conversion ratio is 10:04kv, then the rated current of the low-voltage side is 1kw0,9,000 if the force rate is 0,7 before compensation, and the force rate is 0,8 according to 1kw0, and the stool is 8kw.

    How many kilowatt capacitors should be compensated for when the 800 kVA transformer is no-load? Hello, the active power of the transformer of the pro 800kva: p=s*cos=800*compensation capacity determined by the power factor standard:

    qc=p(tan 1-tan 2)=680*((Therefore, the reactive power compensation capacity of an 800kVA transformer is determined to be 200kvar.) In order to minimize the line loss and voltage loss, it is advisable to balance the compensation on the spot, that is, the reactive power of the low-voltage part should be compensated by the low-voltage capacitor, and the reactive power of the high-voltage part should be compensated by the high-voltage capacitor.

    The power factor proves that your electricity consumption is not small. The grouping of 16 groups should also be reasonable Wang Qing. If you can't vote, you should first check the controller to see if the controller is not set up properly, or it is broken at all.

    If it's a problem with the controller, just reset the controller or replace it. If the controller is fine, then you should consider the problem of harmonics. Because if the harmonic content in the system is large, the capacitor will amplify the harmonic wavelength current, and the capacitor will naturally not be able to be cast when the current is large.

    If this is the case, it is necessary to install a set of filtering compensation devices on the Liling key. If the main components in your capacitor cabinet are of the right specifications, they can also be transformed, so that the cost can be less.

    Summary. Hello dear, if the 1000kva transformer is an ordinary utility transformer, the compensation device is calculated according to 20%-30% of the capacity, that is, 200-300kvar; If it is a factory transformer, 30%-60% of the installed capacity of the compensation device is calculated, that is, between 300-600kvar, according to the real-time reactive capacity selection of the plant's electricity load, and it cannot be undercompensated or overcompensated. Reactive power compensation is a technology that plays a role in improving the power factor of the power supply system, reducing the loss of power supply transformer and transmission line, improving power supply efficiency and improving the power supply environment.

    The reactive power compensation cabinet plays a role in reducing the loss of the power grid and improving the quality of the power grid. The state stipulates that more than 100kVA (transformer) distribution room must do reactive power compensation, and must reach the above, otherwise it will be fined.

    The 1000kva transformer is only about 600A, and the full input of 10 groups of 4OK AF capacitors can only be compensated to a few.

    Hello dear, 1000kva transformer is only 600A left bucket right, 10 groups of 4ok AF capacitor compensation full input can only compensate to a few, this pro, 1000kva transformer compensation capacity is a 30x10=300kvar compensation cabinet. 1) The calculation of the electro-pneumatic destruction current of the main circuit is 433A, and the coefficient to be multiplied is 584A according to the requirements of Yu Meng's above-mentioned specifications, and 630A needs to be configured. , I hope mine can help you!

    Is it a capacitance problem or something, but my capacitor cabinet is only a year.
