Controllable explosion-proof capacitor

Abstract

A controllable explosion-proof capacitor disclosed by the present invention comprises a capacitor shell and a capacitor body which are coaxially arranged, the bottom of the capacitor shell is fixedly connected with a cooling base, the cooling base is provided with an explosion-proof coaming, the explosion-proof coaming and the capacitor shell are coaxial, and the explosion-proof coaming is located at the outer side of the capacitor shell. An insulating plate is arranged in the cooling base in a sealed and sliding mode, and a plurality of compression springs are symmetrically connected between the insulating plate and the inner bottom wall of the cooling base. Compared with a conventional combined spring damping mechanism, the device can prevent the capacitor body from shaking frequently, the position of the capacitor body is not changed when the vibration intensity is small, and when the impact force borne by the capacitor body is large, the kinetic energy of the capacitor body can be converted into the kinetic energy of the cooling liquid and the internal energy of the compression spring, so that the capacitor body is prevented from shaking frequently. And the cooling liquid enters the cooling coil to circulate, so that the phenomenon that more heat is accumulated in the capacitor shell when the capacitor body is used for a long time can be avoided.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to a controllable explosion-proof capacitor. Background technique [0002] Capacitors are widely used in circuit coupling, filtering, energy conversion, circuit control, etc. For large capacitors, it is easier to accumulate more heat during long-term use, and the outside of the capacitor is usually equipped with a shell to protect it Protection further reduces heat exchange. If the capacitor vibrates significantly due to external impact or the instantaneous current is too large due to breakdown, the air pressure in the capacitor case will increase rapidly, which will easily cause the element to expand or even burst. [0003] The conventional capacitor protection and damping mechanism is mostly composed of combined spring components. Although it has a good damping effect, it is easy to cause frequent shaking of the capacitor body and cannot reduce the internal pressure of the comp...
