[0029] The aluminum electrolytic capacitor body 1 and bolt leads 2 together constitute the aluminum electrolytic capacitor body, model number 630V1500UF. This model also has a certain degree of explosion-proof effect. The supplier is Shenzhen Qingquan Electronics Co., Ltd. The aluminum electrolytic capacitor body is fixed to the surface of other parts using clamps. This technology is existing. The working principle of the aluminum electrolytic capacitor body is as follows:
[0030] S1, Formation of the dielectric layer
[0031] During the manufacturing process, the anode aluminum foil undergoes anodizing (applying DC voltage) to form a dense aluminum oxide (Al2O3) insulating layer. The thickness of this aluminum oxide layer is proportional to the voltage, which determines the voltage rating of the capacitor.
[0032] S2, Charge storage under the influence of an electric field
[0033] When a positive voltage is applied (anode connected to positive electrode, cathode connected to negative electrode), the alumina layer of the anode aluminum foil acts as an insulating medium, preventing electrons from passing directly. Ions in the electrolyte (such as negative ions) migrate to the surface of the dielectric layer under the action of the electric field, forming a double electric layer structure to store charge. The charge is stored on both sides of the dielectric layer in the form of an electrostatic field, realizing the capacitance effect.
[0034] S3, polarization characteristics
[0035] Aluminum electrolytic capacitors are polarized capacitors, and the positive and negative terminals should be distinguished. If the reverse voltage exceeds a certain threshold, the aluminum oxide layer may be damaged, leading to overheating, a surge in leakage current, or even an explosion.
[0036] In terms of working principle or structural principle, firstly, during daily use, the aluminum electrolytic capacitor body 1 can be cooled by the heat dissipation holes 303 to prevent high temperature damage to the parts. In the event of an "explosion" or breakage, the casing 302 and the hollow plate 402 can intercept the splashed electrolyte in multiple ways, preventing the electrolyte from spilling onto the surface of other parts and causing damage. If it is necessary to replace the aluminum electrolytic capacitor body 1, the operator can use a tool to rotate the screw 702 to disengage the side plate 701 and the bottom plate 603. Then, the bottom plate 603 can be rotated by using the hinge relationship between the rotating rod 601 and the vertical plate 502, thereby allowing the aluminum electrolytic capacitor body 1 inside the casing 302 to be removed and replaced.
[0037] In summary, this device has advantages such as good heat dissipation and comprehensive explosion protection.
