Abstract

The invention relates to the technical field of power capacitors, and especially relates to an anti-harmonic power capacitor with a connector convenient to replace according to the model of a connecting piece. The capacitor comprises a shell, a heat insulation plate is arranged in an inner cavity of the shell, a reactor is arranged on the left side of the heat insulation plate, and a mounting plate is arranged on the right side of the lower surface of the inner cavity of the shell. Three first sliding grooves are formed in the upper surface of the mounting plate, capacitor fixing devices are installed in the first sliding grooves, a capacitor body is arranged on the upper surface of the mounting plate, the capacitor body is located between the capacitor fixing devices, an adjusting deviceis installed on the upper surface of the mounting plate, three threaded pipes are installed on the upper surface of shell, and the outer side of each threaded pipe is in threaded connection with a threaded cylinder. Through mutual cooperation of the structures, the anti-harmonic capacitor has an anti-harmonic function, the terminals can be conveniently replaced, the service life of the capacitor is prolonged, the capacitor body can be conveniently disassembled and assembled when needing to be maintained, and the working efficiency of capacitor maintenance is effectively improved.

Description

technical field [0001] The invention relates to the technical field of power capacitors, in particular to an anti-harmonic power capacitor which can conveniently replace connectors according to the type of connectors. Background technique [0002] Two conductors that are close to each other, with a layer of non-conductive insulating medium in between, constitute a capacitor. When a voltage is applied between the two plates of the capacitor, the capacitor will store charge. The capacitance of the capacitor is numerically It is equal to the ratio of the amount of charge on a conductive plate to the voltage between the two plates. Capacitors play an important role in tuning, bypassing, coupling, filtering and other circuits. It is used in the tuning circuit of transistor radios. It is also used in the coupling circuit and bypass circuit of color TV sets. With the rapid development of electronic information technology, the upgrading speed of digital electronic products is gettin...

Problems solved by technology

[0003] The application of power electronic equipment is becoming more and more common. Power electronic devices are indispensable in the production process. The harmonics generated by these non-linear electrical equipment can lead to waste of electric energy, reduce system capacity, accelerate equipment aging, reduce productivity, If the power distribution system itself or other equipment connected to the system fails, and the existing capacitor terminals are generally of fixed design, long-term use will easily lead to poor contact and difficult cleaning. There are anti-harmonic capacitors. The internal capacitance is not easy to disassemble and maintain, and it takes a lot of time to disassemble.
