Abstract

The invention discloses a glass capacitor and an encapsulating device. The glass capacitor comprises a glass medium layer, a first metal electrode layer and a second metal electrode layer, wherein the first metal electrode layer is attached to one side of the glass medium layer; the second metal electrode layer is attached to the other side of the glass medium layer, and is centrally symmetrical to the first metal electrode layer; the first metal electrode layer is rectangular; one end of the first metal electrode layer is taken as the leading-out end 2b of an electrode 2a, and the other three ends of the first metal electrode layer form reserved edges 3a, 3b and 3c together with corresponding boundaries of the glass medium layer respectively; the reserved edges 3a, 3b and 3c are taken as insulated ends; the leading-out end 2b is flush with the glass medium layer; and the thickness of the leading-out end 2b is larger than that of the electrode 2a. The energy storage density of the glass capacitor provided by the invention is much higher than that of polypropylene; alkali-free glass is adopted, so that the application environment temperature of the capacitor can be raised greatly; and due to the adoption of the alkali-free glass, local surface discharge caused by surface unevenness can be weakened, and the working stability of the glass capacitor is enhanced.

Description

technical field [0001] The invention belongs to the field of high-voltage electrical appliances, and more specifically relates to a glass capacitor and a packaging device. Background technique [0002] Capacitors are widely used as energy storage, filtering and reactive power compensation devices in power electronics and power systems. Its capacitance is proportional to the dielectric constant of the energy storage medium. Under the condition that the thickness of the energy storage medium is fixed, the working voltage of the capacitor is proportional to the working field strength. In order to increase the energy storage density of capacitors and reduce their space requirements as energy storage components, it is necessary to further increase the working field strength and dielectric constant of capacitors. At present, biaxially oriented polypropylene materials are widely used as the medium of high-density energy storage capacitors. However, due to the characteristics of po...
