A capacitor with high safety

Abstract

The invention discloses a high-safety capacitor, which belongs to the field of capacitors. A high-safety capacitor includes a capacitor shield, and the capacitor shield includes an insulating jacket fixedly connected sequentially from outside to inside, a fitted stretchable net and a resistor. The flame-retardant sheath, the side of the embedded telescopic net close to the flame-retardant sheath is connected with multiple deformation recovery components, the inner end of the deformation recovery component penetrates the flame-retardant sheath, and is fixedly connected with a buffer adsorption ball, which is set on the inner wall of the capacitor shell Buffer the adsorption balls to effectively prevent the internal burning and damage of the power supply device, and also improve the breakdown resistance of the capacitor shell, and through the cooperation of flame-retardant adsorption particles and deformation recovery components, a reinforcement is made for the embedded telescopic net. To improve the service life of the capacitor, an alarm controller and an internal self-alarm system are set up to send a reminder signal to the staff at the external end in time to improve the safety of the capacitor.

Description

technical field [0001] The invention relates to the field of capacitors, more specifically, to a capacitor with high safety. Background technique [0002] Two conductors that are close to each other, with a layer of non-conductive insulating medium in between, constitute a capacitor. A capacitor stores charge when a voltage is applied between its two plates. Capacitors play an important role in tuning, bypassing, coupling, filtering and other circuits. They are used in tuning circuits of transistor radios, and in coupling circuits and bypass circuits of color TV sets. [0003] Since a capacitor is a "container" that stores charges, there is a problem with the size of its "capacity". In order to measure the ability of a capacitor to store charge, the physical quantity of capacitance is determined. Capacitors must be under the action of an applied voltage to store charge. Different capacitors may also store different amounts of charge under voltage. In addition to the eff...

Problems solved by technology

[0004] When the capacitor is working, due to the overvoltage of the internal power supply device, the discharge will break down the shell, and the shell will easily expand or crack, and even the shell will burst. The existing inner wall of the capacitor shell does not have a certain degree of self-repair function. , at the same time, there is no alarm function when a failure occurs inside the shell. Therefore, we propose a capacitor with high safety to solve the above problems
