Embodiment 1
[0028] refer to figure 1 , a high-temperature-resistant ultra-quiet explosion-proof sealed capacitor, including a metal case 1, the outer surface of the metal case 1 is sprayed with medium green gray baking paint 2, the middle and bottom of the metal case 1 are equipped with sensors 3, and the upper end of the inner wall of the metal case 1 is fixed. Tantalum cover 4, the middle part of the lower end of the tantalum cover 4 is connected with an insulating layer 5, the inner side of the insulating layer 5 is provided with a tantalum powder sintered block 6, the upper end of the tantalum powder sintered block 6 is fixedly connected with a positive nickel wire 7, and the lower end of the tantalum powder sintered block 6 deviates from One side of the positive nickel wire 7 is fixedly connected with the negative copper wire 8, the outer side of the insulating layer 5 is provided with a sound-absorbing layer 9, the outer side of the sound-absorbing layer 9 is provided with a heat-res...
Embodiment 2
[0031] Such as figure 1 and 2 As shown, this embodiment is basically the same as Embodiment 1. Preferably, the sound-absorbing layer 9 includes an adhesive layer 901 and a porous layer 902. The porous layer 902 is glued and fixed to the adhesive layer 901, and the porous layer 902 is located close to the insulating layer 5. side.
[0032] In this embodiment, the porous layer 902 is glued and fixed inside the adhesive layer 901 , so as to absorb the noise generated by the capacitor, thereby ensuring the sound-absorbing effect of the capacitor.
Embodiment 3
[0034] Such as figure 1 As shown, this embodiment is basically the same as Embodiment 1. Preferably, the heat-resistant layer 10 is a mixture of methyl-terminated vinyl silica gel G795, heat-resistant agent, and silicon nitrogen.
[0035] In this embodiment, the heat-resistant layer 10 is made by mixing methyl-terminated vinyl silica gel G795, heat-resistant agent, and silicon nitrogen. Since vinyl silica gel G795 and heat-resistant agent have good heat resistance, and the mixture of the two will not When chemical reaction occurs, the performance of the substance will not change, so that the heat-resistant layer 10 achieves a good heat-resistant effect.

Abstract
The invention discloses a high-temperature-resistant ultra-silent explosion-proof sealed capacitor, which comprises a metal shell. Medium-green grey baking varnish is sprayed on the outer surface of the metal shell. Sensors are mounted in the middle and at the bottom of the metal shell; a tantalum cover is fixedly connected to the upper end of the inner wall of the metal shell; an insulating layeris connected to the middle of the lower end of the tantalum cover; tantalum powder agglomerates are arranged on the inner side of the insulating layer; one side of the upper end of the tantalum powder agglomerate is fixedly connected with a positive nickel wire; one side of the lower end of the tantalum powder agglomerate deviating from the positive nickel wire is fixedly connected with a negative copper wire; a silencing layer is arranged on the outer side of the insulating layer; a heat-resisting layer is arranged on the outer side of the silencing layer; an explosion-proof layer is arranged on the outer side of the heat-resisting layer; and high-temperature resin fills gaps between the explosion-proof layer and the inner wall of the metal shell, between the heat-resisting layers, between the heat-resisting layer and the silencing layer and between the silencing layer and the insulating layer. Good silencing, heat-resisting and explosion-proof effects can be achieved, parameters ofthe capacitor during working are monitored in real time, and the use safety of the capacitor is well guaranteed.
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...
