Abstract

The utility model discloses an explosion-proof capacitor, including a shell and electrolyte sealed in the shell. The top part and the bottom part of the shell are provided with an outgoing line and a bottom shell respectively. A plurality of criss-crossing ribs are disposed on the surface of the bottom shell. The ribs and the bottom shell are integrally molded. The criss-crossing ribs form a plurality of #-shaped pits, greatly improving the loading capacity of the bottom shell. When pressure in the capacitor reaches a critical value and the capacitor explodes, the bottom shell splits in #-shaped manner, and the electrolyte leaks from cracks rather than ejection, thus the risks caused by capacitor explosion is greatly reduced.

Description

A kind of explosion prevention capacitor

Technical field

The utility model relates to a kind of electric elements, particularly a kind of explosion prevention capacitor.

Background technology

Existing liquid electric capacity, during work, after temperature rises to certain value, the electrolyte of the electric capacity the inside generation gas that can seethe with excitement, cause the electric capacity internal pressure to rise, will explosion when rising to capacitance shell and can't bear, understand some electrolyte and hydrogen injection after the explosion out, with on fire easily after the airborne combination with oxygen, thereby bring great potential safety hazard.

Summary of the invention

The purpose of this utility model provides a kind of not ignitable explosion prevention capacitor.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of explosion prevention capacitor, comprise shell and be sealed in the interior electrolyte of shell, cover top portion and bottom are respectively equipped with lead-out wire and drain pan, and described drain pan surface is provided with many crisscross fins.

Wherein, described fin and drain pan are one-body molded.

The beneficial effects of the utility model are: be provided with crisscross fin on the electric capacity drain pan, form a plurality of groined type pits, greatly improved the bearing capacity of drain pan, when the pressure of electric capacity inside reaches the critical value explosion, drain pan is groined type and splits, electrolyte can ooze out from the crack rather than eject, thereby greatly reduces the risk that the electric capacity explosion causes.

Fig. 2 is upward view of the present utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

With reference to Fig. 1, shown in Figure 2, the utility model discloses a kind of explosion prevention capacitor, comprise shell 1 and be sealed in electrolyte 2 in the shell 1, shell 1 top and bottom are respectively equipped with lead-out wire 3 and drain pan 4, described drain pan 4 surfaces are provided with crisscross many fins 5, described fin 5 is one-body molded with drain pan 4, crisscross fin 5 forms a plurality of groined type pits, greatly improved the bearing capacity of drain pan 4, when the pressure of electric capacity inside reaches the critical value explosion, drain pan 4 is groined type and splits, and electrolyte can ooze out from the crack rather than eject, thereby greatly reduces the risk that the electric capacity explosion causes.

Above-described embodiment is illustrative principle of the present utility model and effect thereof only; and the embodiment of part utilization; for the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection range of the present utility model.

Claims

1. an explosion prevention capacitor comprises shell and is sealed in the interior electrolyte of shell, and cover top portion and bottom are respectively equipped with lead-out wire and drain pan, it is characterized in that: described drain pan surface is provided with many crisscross fins.

2. explosion prevention capacitor according to claim 1 is characterized in that, described fin and drain pan are one-body molded.
