Description

Novel capacitor

Technical Field

The utility model belongs to the technical field of electronic equipment, especially, relate to a novel explosion-proof capacitor.

Background

The pressure valve of current electric capacity sets up near anodal and negative terminal, and electrolyte is electrically conductive, and traditional structure spouts electrolyte from the pressure valve and can switch on positive negative terminal, leads to the electric capacity to strike sparks, ignites electrolyte, brings danger.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve the problem that pressure valve blowout electrolyte leads to electric capacity to catch fire, the utility model provides a novel electric capacity, including the electric capacity body, the electric capacity body top is equipped with the end cover, the electric capacity body outside is equipped with the casing, the electric capacity body below is equipped with the bottom plate, be equipped with positive pole and negative pole on the electric capacity end cover, the pressure valve has on bottom plate or the casing, casing and bottom plate integrated into one piece.

Preferably, the bottom plate is provided with a thickness reduction area, the thickness reduction area forms the pressure valve, and the release pressure of the thickness reduction area is 0.8-2.0 MPa. The pressure valve is arranged at the thinnest position, when the pressure in the capacitor is too high, the electrolyte can be sprayed out from the thinnest position firstly, the anode and the cathode cannot be contacted, and the safety is improved.

Further, the shell is provided with a thickness reduction area, the thickness reduction area forms the pressure valve, and the release pressure of the thickness reduction area is 0.8-2.0 MPa. The pressure valve is arranged on the shell, when the internal pressure of the capacitor is overlarge, the electrolyte can be sprayed out from the thinnest part firstly, and the anode and the cathode cannot be contacted, so that the safety is improved.

Preferably, the shell outside the capacitor body is an explosion-proof shell.

Has the advantages that: the utility model discloses set up the electric capacity pressure valve on the bottom plate, when electrolyte from the pressure valve blowout, can't contact positive pole and negative terminal, avoided the fire, improved the security.

Detailed Description

Example one

As shown in fig. 2, a novel capacitor comprises a capacitor body, an end cover 4 is arranged above the capacitor body, a bottom plate 6 is arranged below the capacitor body, an anode 1 and a cathode 2 are arranged on the capacitor end cover 4, a pressure valve 5 is arranged on the bottom plate 6, and the shell 3 and the bottom plate 6 are integrally formed. The bottom plate 6 is provided with a thickness reduction area, the thickness reduction area forms the pressure valve 5, and the release pressure of the thickness reduction area is 0.8-2.0 MPa. The shell 3 is an explosion-proof shell. And an insulating sleeve is arranged on the outer side of the shell 3.

The specific working principle is as follows: in order to improve the safety of the capacitor, the pressure valve 5 is arranged on the bottom plate 6, and when the electrolyte is sprayed out of the pressure valve 5, the electrolyte cannot contact the positive electrode 1 and the negative electrode 2, so that the safety of the capacitor is improved.

Example two

The difference from the first embodiment is that: as shown in FIG. 3, the housing 3 has a reduced thickness region which forms the pressure valve 5, and the relief pressure of the reduced thickness region is 0.8 to 2.0 MPa.

The specific working principle is as follows: in order to improve the safety of the capacitor, the pressure valve 5 is arranged on the shell 3, when the pressure exceeds 0.8-2.0 MPa, the electrolyte can be sprayed out from the pressure valve 5, and at the moment, the pressure valve is arranged on the shell, so that the anode 1 and the cathode 2 can not be contacted, and the safety of the capacitor is improved.
