A high temperature resistant ultra-quiet explosion-proof sealed capacitor

Abstract

The invention discloses a high-temperature-resistant ultra-quiet explosion-proof sealed capacitor, which comprises a metal shell, the outer surface of the metal shell is sprayed with medium green gray baking paint, sensors are installed in the middle and bottom of the metal shell, and the upper end of the inner wall of the metal shell is fixedly connected to the There is a tantalum cover, and the middle part of the lower end of the tantalum cover is connected with an insulating layer. A sintered block of tantalum powder is arranged on the inner side of the insulating layer. The upper end of the sintered block of tantalum powder is fixedly connected with a positive nickel wire, and the lower end of the sintered block of tantalum powder is away from the positive nickel wire. The negative electrode copper wire is fixed on the side of the insulation layer. A sound-absorbing layer is provided outside the insulating layer. A heat-resistant layer is provided outside the sound-absorbing layer. An explosion-proof layer is provided outside the heat-resistant layer. High-temperature resin is filled between the heat-resistant layer and the sound-absorbing layer, and between the sound-absorbing layer and the insulating layer. The invention can achieve good noise reduction, heat resistance and explosion-proof effects, and can monitor the parameters of the capacitor during operation in real time, thus ensuring the safety of the capacitor.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to a high-temperature resistant ultra-quiet explosion-proof sealed capacitor. Background technique [0002] Capacitors are usually called capacitance, and capacitance is also called capacitance, which refers to the amount of charge stored under a given potential difference. Charges will move under force in an electric field. When there is a medium between conductors, it will hinder the movement of charges and make The charge accumulates on the conductor, resulting in the accumulation and storage of charge, and the stored charge is called capacitance. Capacitor is a common electronic component in electronic equipment, which is used in DC blocking, coupling, bypass, filtering, tuning loop, energy conversion, In terms of control circuits, etc., in the prior art, capacitors will generate heat energy during long-term use. For example, the capacitor casing is prone to explosion in a hi...
