Abstract

The invention discloses a pulse capacitor used for a rapid discharging unit. The pulse capacitor comprises: a capacitor leading electrode plate, which is directly covered on an end surface of a capacitor serial module and is pressed tightly as well as is led out of a plastic housing by a cylinder electrode; a capacitor and switch discharging branch switch electrode; a capacitor side surface charging electrode, which is connected with the leading electrode plate inside the housing; a packaging plastic housing and a sealing ring and the like. All assemblies of a capacitor slug are formed by metal electrode plates and dielectric film materials by a winding mode; the plurality of assemblies are in series connection to form the capacitor slug; and the metal electrode plates at two ends of the capacitor slug are respectively connected with the capacitor leading electrode plate. According to the invention, the pulse capacitor employing the above-mentioned structure has a good insulation characteristic and is not easy to be broken down; besides, the material stability is good and service life is long. In addition, there is no welding point inside the capacitor slug and safety coefficient is high.

Description

Technical field: [0001] The invention relates to the technical field of pulse power, in particular to a pulse capacitor used for a fast discharge unit. Background technique: [0002] Fast pulse discharge has a very wide range of applications in high voltage technology, pulse power and other fields. Generally speaking, high-voltage pulse capacitors used for fast pulse discharge mainly have two structures. One is the paper inner string structure, that is, aluminum foil is used as an electrode and a composite medium composed of plastic film or insulating paper and film is wound into a capacitor; The other is a full-film metallization structure, that is, a plastic film or insulating paper is plated with a very thin metal layer as an electrode in a vacuum state, and then wound to form a capacitor. However, the pulse capacitors of these two structures have defects such as low safety factor, large volume, small current-carrying capacity, and short service life. In the present inv...
