Capacitor with high safety

Abstract

The invention discloses a high-safety capacitor and belongs to the field of capacitors. The high-safety capacitor comprises a capacitor protection shell, wherein the capacitor protection shell comprises an insulating outer sleeve, an embedded telescopic net and a flame-retardant sheath which are fixedly connected in sequence from outside to inside, and one side, close to the flame-retardant sheath, of the embedded telescopic net is connected with a plurality of deformation recovery assemblies; an inner end of the deformation recovery assembly penetrates through the flame-retardant sheath and is fixedly connected with a buffer adsorption ball, and the buffer adsorption ball is arranged on an inner wall of the capacitor protection shell, so a purpose of effectively preventing the interior of a power supply device from being burnt and damaged is achieved, breakdown resistance of the capacitor protection shell is improved, and the flame-retardant adsorption particles are matched with the deformation recovery assemblies, the embedded telescopic net is reinforced, the service life of the capacitor is prolonged, meanwhile, an alarm controller and a self-alarm system in the alarm controller are arranged, a reminding signal is timely sent to a worker from an outer end, and use safety of the capacitor is improved.

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
