High-temperature-resistant explosion-proof capacitor

Abstract

The invention discloses a high-temperature-resistant explosion-proof capacitor which comprises a shell, a sand layer and a mounting seat. A mounting frame is mounted on one side of the shell, the sand layer is arranged in the shell, a temperature sensor is mounted in the sand layer, the mounting seat is mounted at the bottom in the shell, a first conductor sheet is mounted at the top of the mounting seat, a second conductor sheet is mounted on the mounting seat on the inner side of the first conductor sheet, an insulating cover is mounted at the tops of the first conductor sheet and the second conductor sheet, a container is mounted at the top of the mounting seat on the inner side of the second conductor sheet, a wire is mounted in the container, and the end part of the wire penetrates through the shell and is provided with a resistor. According to the capacitor, the sand layer is installed in the shell, the buffer effect on explosion impact is large due to the fact that the sand layer is loose, and when the capacitor explodes accidentally, due to the fact that the sand layer is used for buffering, serious damage to an electric appliance caused by explosion is avoided, and the protection measures of the capacitor on explosion are effectively improved.

Description

technical field [0001] The invention relates to the technical field of capacitor production, in particular to a high temperature resistant explosion-proof capacitor. Background technique [0002] Capacitor is one of the electronic components widely used in electronic equipment. It is widely used in DC blocking, bypass, filtering and control in circuits. Any two conductors that are insulated from each other and are very close to each other form a capacitor. , During the use of the capacitor in the circuit, due to the excessive current in the circuit, it is easy to cause the capacitor to generate high temperature and cause an explosion. At this time, a high temperature resistant explosion-proof capacitor is needed. [0003] The disadvantages of existing capacitors are: [0004] 1. The current blocking ability of the existing capacitor is poor. When the current is too strong, it is easy to cause high temperature and cause the danger of explosion; [0005] 2. The existing capa...

Problems solved by technology

[0004] 1. The current blocking ability of the existing capacitor is poor. When the current is too strong, it is easy to cause high temperature and cause the danger of explosion;

[0005] 2. The existing capacitors have poor temperature perception and cannot provide early warning, which can easily lead to explosions;

[0006] 3. The internal structure of the existing capacitor is relatively simple, and its safety factor is low. Once it explodes, it may cause damage to the entire electrical appliance. Therefore, we propose a high-temperature-resistant explosion-proof capacitor to solve the existing problems.
