Description

technical field

The invention relates to the technical field of power distribution equipment, in particular to a complete set of reactive power compensation devices on a high-voltage column capable of rapidly replacing capacitors.

Background technique

The main function of the reactive power compensation device is to compensate the loss of reactive power from the power system in the power supply area. It is usually erected on a high-voltage column and used in conjunction with the lines in the power system to increase the bus voltage and maintain a relatively stable system voltage. This is also an important guarantee link for the power quality of the power supply system, but the load on the user side is constantly changing, so the required reactive power gap is also different, so the reactive power compensation needs to take corresponding actions, and the use is more reasonable. Compensation capacity to cope with and requires rapid response.

The existing reactive power compensation device is divided into a capacitor device part and a cabinet switch part. The cabinet switch part includes circuit breakers, contactors, isolation switches, series reactors, lightning arresters, fuses and relay protectors installed in the cabinet. and other devices, in which the capacity of the capacitor device is configured according to the ratio of the rated capacity of the main transformer, and it is a fixed value. When using, the capacitor device is connected to the power grid through the switch cabinet as required, so as to perform reactive power compensation on the power grid. When the voltage of the power system is low or there is a lack of reactive power, the device is put in to increase the voltage and compensate for the reactive power; when the voltage of the power system is high or the reactive power is too much, the device is cut off to reduce the voltage and reduce the reactive power. Switching and switching operations achieve the purpose of adjusting voltage and balancing reactive power. During operation, the device can only be put in or removed with full capacity, and it is difficult to expand the capacity.

To sum up, the existing reactive power compensation device still has the following problems in actual use: the capacity of the capacitor device is fixed, even if the capacity is changed by replacing the capacitor, the volume of the capacitor will change after the capacity is changed. The change makes the installation and connection position of the capacitor device in the switch cabinet also change accordingly. It is no longer suitable for installation with electrical equipment such as contactors, and the traditional installation method requires dismantling the switch cabinet door and then disassembling the entire capacitor device. Removing, the operation process is cumbersome and difficult. It can be seen that the existing reactive power compensation device usually cannot be replaced by capacitors, and the applicability is poor. Therefore, the entire reactive power compensation device can only be replaced, and the manufacturing cost is high. Usage requirements.
