Description

Technical Field

[0001] The present invention relates to the technical field of capacitor production, and in particular to a capacitor production and manufacturing method. Background Art

[0002] A capacitor is an electronic component whose main function is to store and release charge in a circuit. The construction of a capacitor usually consists of two conductive plates and a dielectric material, and the conductive plates are separated by the dielectric material. The capacity of the capacitor depends on the area of ​​the conductive plates, the properties of the dielectric material, and the distance between the conductive plates. Capacitors are widely used in circuits, including but not limited to the following aspects: Tuning: In radio communications, capacitors are used to adjust the frequency of the circuit so that it can receive or transmit signals of a specific frequency. Coupling: In an amplifier circuit, capacitors are used to connect amplifiers at various levels so that signals can be transmitted while blocking the transmission of DC voltage. Filtering: In a power supply circuit, capacitors are used to smooth voltage fluctuations and provide a stable DC voltage. Decoupling: In a circuit, capacitors are used to eliminate fluctuations in the power supply voltage to prevent these fluctuations from affecting the operation of the circuit. Passing AC and blocking DC: In a circuit, a capacitor can allow AC signals to pass while blocking DC signals.

[0003] There are many types of capacitors, including fixed capacitors, variable capacitors, and semi-variable (fine-tuning) capacitors. Different types of capacitors have different applications in circuits. In particular, some high-voltage capacitors and power capacitors may use insulating oil as an impregnant. This insulating oil can help improve the electrical properties of the capacitor, such as increasing the capacitance value and reducing the loss factor. In addition, the insulating oil can also play a role in cooling and moisture protection.

This method produces a capacitor core that meets the preset electrical parameter requirements, performs corresponding packaging on the cylindrical shell, fills the capacitor core in the cylindrical shell with oil, and performs pre-factory inspection on the AC tuning capacitor, so as to produce and manufacture AC tuning capacitors that meet the electrical and physical properties required by filter capacitors on vehicle equipment such as AC locomotives, and ensure the safety and reliability of the subsequent use of the AC tuning capacitor and the operation of the vehicle equipment to which the AC tuning capacitor is applied.
