Abstract

A thin-film capacitor structure integrated with a shielding function disclosed by the present invention comprises a thin-film capacitor element, a controller assembly, an outer shell and a top cover shell. The interior of the outer shell is a shielding protection bin, and inner shielding layers are uniformly distributed on the side surface of the shielding protection bin; the upper end and the lower end of the shielding protection bin are provided with a shielding partition plate and a shielding bottom plate respectively to form an integral shielding protection structure, the shielding partition plate is located between the outer shell and the top cover shell, a main cooling fan and an auxiliary cooling fan are arranged in the outer shell and the top cover shell respectively, and a temperature sensor is installed in the outer shell. The thin-film capacitor structure integrated with the shielding function is provided with an all-dimensional shielding protection bin structure composed of an inner shielding layer, a shielding partition plate and a shielding bottom plate, and is also provided with a movable baffle plate structure which is arranged between a top cover shell and a shielding protection bin and plays a role in airflow linkage adjustment; ventilation heat dissipation or closed shielding protection can be flexibly adjusted and started through a linkage structure.

Description

technical field [0001] The invention relates to the related technical field of capacitors, in particular to a film capacitor structure with integrated shielding function. Background technique [0002] Capacitors are widely used in power systems and electrical equipment. The basic principle is that any two conductors are separated by an insulating medium such as an insulating film to form a capacitor. In low-voltage power distribution, power capacitors are often used. Low-voltage power capacitors can be used as a reactive power compensation device, and have the advantages of low energy consumption, small size, long service life and high reliability. [0003] However, when the existing low-voltage power capacitor is installed and used, the shielding protection function is often not perfect, such as poor electromagnetic shielding effect, poor sound insulation and noise reduction effect, and is easily affected by environmental factors such as static electricity and dust. Now the...
