Explosion-proof rail transit locomotive capacitor

Abstract

The invention relates to an explosion-proof rail transit locomotive capacitor, which comprises a base, a buffer mechanism, a third heat dissipation mechanism and a body, and is characterized in that the third heat dissipation mechanism is detachably connected to the periphery of the body, the third heat dissipation mechanism comprises a protection shell, a heat dissipation filler and a heat conduction rod, an inner groove is formed in the protection shell, and the heat dissipation filler is filled in the inner groove. The buffer mechanism can provide a buffer effect on the body, the body is prevented from being in a hard contact shaking state, components in the body are prevented from being damaged, one end of the heat conduction rod makes contact with the body and the other end of the heat conduction rod makes contact with the heat dissipation filler under the action of the heat conduction rod while buffering is conducted, heat generated on the body can be conducted out through the heat conduction rod and then transmitted into the heat dissipation filler, the heat is transmitted into the heat dissipation holes through the heat dissipation filler, then the heat is rapidly dissipated outside, heat dissipation and buffering can be conducted on the body at the same time, and meanwhile the situation that the capacitor bursts can be avoided.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to an explosion-proof rail transit locomotive capacitor. Background technique [0002] Two conductors that are close to each other, with a layer of non-conductive insulating medium in between, constitute a capacitor. When a voltage is applied between the two plates of the capacitor, the capacitor will store charge. The capacitance of a capacitor is numerically equal to the ratio of the amount of charge on a conductive plate to the voltage between the two plates. Capacitors play an important role in tuning, bypassing, coupling, filtering and other circuits. A capacitor is an element that stores electricity and electrical energy (potential energy). A conductor surrounded by another conductor, or the electric field lines emitted by one conductor all terminate in another conductor, is called a capacitor. The rail locomotive will shake when it is running, which will cause the loc...

AI Technical Summary

Problems solved by technology

The rail locomotive will shake when it is running, which will cause the locomotive capacitor to be in a state of constant shaking. In the state of constant hard contact shaking, the internal components of the capacitor will be damaged, and the capacitor will generate more internal components when it is in use. In the case of constant shaking, as the heat continues to rise, the damage speed of components will be accelerated, which not only reduces the service life of the capacitor, but also accelerates the expansion speed of the capacitor, which will cause the capacitor to burst. Greatly reduces the use efficiency of rail transit locomotive capacitors, so it cannot meet the needs of existing technologies
