Description

Technical Field

[0001] The utility model relates to the technical field of reactive power compensation capacitors, and more specifically, to a reactive power compensation capacitor. Background Art

[0002] Capacitors are basic electrical components used to store charge and electrical energy. They are typically composed of two conductors (called plates) separated by an insulating medium (called a dielectric). When voltage is applied to the two plates, the capacitor accumulates charge between the plates, forming an electric field and storing electrical energy. In power systems, power factor refers to the ratio of useful power to apparent power. Reactive power compensation capacitors can compensate for reactive power in circuits by introducing capacitors into the circuit, thereby improving the power factor of the system. By adjusting the flow of reactive power, transmission losses can be reduced, grid stability can be improved, and overheating of equipment can be reduced.

[0003] The Chinese patent publication number CN217214470U discloses a reactive compensation capacitor, in which a metallized film core is installed inside the reactive compensation capacitor body, a resistor shell is fixedly connected to the top of the metallized film core, and a terminal is fixedly connected to the outside of the resistor shell. By providing a base, the resistor shell is rotated to separate the external thread inside the base from the internal thread inside the reactive compensation capacitor body, and the wire connected to the terminal is removed by a screwdriver, thereby facilitating the removal of the metallized film core and the resistor shell from the inside of the reactive compensation capacitor body through the base, making it convenient to repair the metallized film core.

[0039] The capacitor body 1 in this solution is mainly used in a reactive power compensation device. The reactive power compensation device is a device used to improve the power factor in an electric power system. The power factor is an indicator that measures the effective utilization of electric energy by a circuit. By improving the power factor of the system, the reactive power flow in the circuit can be changed, thereby reducing transmission losses and improving grid stability.

[0048] Working principle: When using the device, three studs 62 are installed on the fixing plate 61. The bottom of the stud 62 passes through the pad 4 and the top cover 3 and is connected to the inside of the capacitor body 1. A thread is provided on the top of the stud 62, so that it can form a threaded terminal, so that it can be directly used for wiring.
