    In the low-voltage distribution part there are incoming cabinets, outgoing cabinets, of course, capacitor repair cabinets, so what is the role of the capacitor compensation cabinet, as the name suggests is to play the role of capacitance supplement, first look at the principle of capacitance supplement, capacitance and load are connected in parallel, capacitance is the same as the power library, when the load increases, due to the internal resistance of the power supply, the output voltage of the power supply will drop, because the two ends of the capacitor to maintain the original voltage, that is, the capacitor in the capacitor to flow out of a part, delaying the downward trend of voltage, which is the principle of capacitance supplementation.

    1. The compensation principle of power capacitors.

    A capacitor is in principle equivalent to a generator that generates capacitive reactive current. The principle of reactive power compensation is to connect a device with a capacitive power load and an inductive power load in parallel on the same capacitor, and the energy is converted between the two loads. In this way, the load on the transformers and transmission lines in the grid is reduced, and the output functional force is increased.

    In the case of a certain amount of active power output, the loss of the power supply system is reduced. Capacitors are comparatively the easiest and most cost-effective way to reduce the load on transformers, power supply systems, and industrial power distribution. Therefore, it is imperative for capacitors to be used as reactive power compensation for power systems.

    At present, it is very common to use shunt capacitors as reactive power compensation devices.

    After the capacitor of the power distribution room is turned off, all the capacitors will no longer run, which will affect our electricity consumption, and the reactive power automatic compensator installed inside will also have problems.

    Safety precautions for power transmission in the distribution room.

    1. The power distribution room must be cleaned regularly every day to maintain a cleanliness of the power distribution room, and some sundries and cables can not be left in the power distribution room.

    2. If you want to enter the power distribution room for power transmission, you must wear the corresponding insulating shoes, insulating gloves and insulating rods, etc., when entering the power distribution room for power transmission, try not to enter alone, you need to find two people together, one person is responsible for power transmission, one person is responsible for supervision, to prevent accidents, the other person can be rescued urgently.

    3. When the power is transmitted, the on-site personnel of the power transmission also need to carefully check the simulation diagram of a system in the room. The operator needs to confirm the range of power transmission according to the sequence of operations on this drawing.

    If the load is an inductive load, without a compensation cabinet, the power factor will be reduced, the actual load power of the line will be reduced, the power supply facilities and line loss will increase, and the power supply bureau will be fined when it is lower than a certain value.

    The capacitors in the distribution cabinet are used for reactive power compensation, which is to improve the power factor of the system and save electric energy. Wherever the power factor needs to be improved, reactive power compensation is required, or a capacitor bank is needed. Only the reactive capacitance compensation cabinet will use capacitors.

    In the power system, motors and other devices with coils are used in many ways. This type of equipment has a part of the current to do work, and a part of the inductor current that does not do work. This makes the current on the line extra large, and the power factor is used to measure the current that does not do work.

    The additional burden on generators, power transformers and power distribution devices is also larger, which not only reduces the utilization rate of lines and power equipment, but also increases the power loss on the line, increases the voltage loss, and reduces the quality of power supply.

    The most convenient way to improve the power factor is to parallel the capacitors, generate capacitive current to offset the inductor current, and reduce the so-called reactive current that does not do work to a certain range. Slow noisy reactive power supply and active power supply, is to ensure the quality of power indispensable part of the service, in the power system should maintain the reactive balance, otherwise, will make the key system voltage decrease, equipment damage, power factor decrease, serious, will cause voltage collapse, system cracking, resulting in a large area of power outage accidents.

    The capacitance compensation of the distribution cabinet is based on the above reasons. The significance of capacitance compensation in the distribution cabinet is to solve the insufficient reactive power capacity of the power grid, install reactive power compensation equipment, improve the power factor of the network, reduce loss and save electricity, and make the power system operate safely.

    The overcurrent of the capacitor in operation is generally caused by overvoltage or higher harmonics. The standard states that the capacitor can be operated at times the rated current. Since the capacitance value of the permissible capacitor has a 10% error, the actual allowable overcurrent can reach times the rated current.

    If the overcurrent of the capacitor bank exceeds the above allowable value, the capacitor bank should be disconnected from the network and appropriate measures should be taken to eliminate the cause of the high overcurrent before continuing operation. If the capacitor bank or digging overcurrent is caused by overvoltage, I hope I can help you <>

    When the capacitance compensation capacitor of the distribution cabinet needs to be discharged, you can follow the following steps to operate Zhaopei: 1First of all, the power supply needs to be disconnected from the capacitor to avoid the risk of electric shock during the discharge process.

    2.Then, using a special tool for discharge, it is necessary to connect it to both ends of the capacitor to ensure that the capacitor can be discharged quickly and completely. 3.

    Next, you need to follow the instructions for using the tool, usually by inserting the tool into both ends of the capacitor for a few seconds until the capacitor is fully discharged. 4.Finally, confirm that the capacitor has been fully discharged before proceeding with other operations, such as service, replacement, or maintenance.

    It should be noted that during the discharge process, it is necessary to pay attention to safety to avoid electric shock or other accidents. At the same time, it is also necessary to understand the specific parameters and characteristics of the capacitor before operation to ensure that the operation can be carried out correctly.

    Whether the capacitors in the capacitor cabinet in the distribution room are connected in parallel or in series in the three-phase circuit, and the capacitors are stored in direct current, why.

    1.The capacitors in the capacitor cabinet can be connected in parallel, or they can be connected in series. The shunt capacitor can reduce the total capacitance of the circuit, and the series capacitor can be used to compensate for the total capacitance of the sail.

    2.The capacitors in three-phase circuits store direct current because they can filter out fluctuations in alternating current, keeping the voltage stable. Capacitors can compensate for the power loss caused by resistance in three-phase circuits and improve the power factor of the power system.

    In addition, capacitors can also eliminate electromagnetic interference in the power grid and reduce unbalanced currents in the power grid, thereby improving the reliability and safety of the power grid.

The current of the capacitor compensation cabinet is only related to the capacity of the capacitor, and has nothing to do with the load. Capacitance is power factor related to making and disconnecting. Your thermal protection jump may be a mismatch between the thermal protection and the capacitor, the setting current is too small, or the capacitance compensation is too frequent, and the power factor and the compensation value are not matched, causing a group of capacitors to be engaged and disconnected.

When a capacitor is put in, it will generate an inrush current that is more than 5 times greater, and unless a larger reactor is added, the inrush current may cause a quick-break protection operation. If it is a trip caused by the inrush current (the input is tripped instantly), the inrush current will be greater if the reactor is removed, so it is not recommended to remove the reactor, and the setting time limit of the superior circuit breaker can only be appropriately adjusted in this situation; If the capacitor trips after a few seconds of input, it should be considered that it is caused by harmonic resonance, and the reactor can be removed.
