Technical Field

[0001] The utility model relates to the technical field of capacitors, in particular to a capacitor with a fireproof function. Background Art

[0002] Two conductors close to each other with a layer of non-conductive insulating medium in between form a capacitor. When voltage is applied between the two plates of the capacitor, the capacitor will store charge. The capacitance of the capacitor is numerically equal to the ratio of the charge on one conductive plate to the voltage between the two plates.

[0003] The existing capacitors on the market do not have fireproof properties. When a capacitor catches fire, it is easy to cause an explosion. For this reason, we propose a capacitor with fireproof function. Utility Model Content

[0004] The purpose of the utility model is to provide a capacitor with fire protection function to solve the problems raised in the above background technology.

[0013] Preferably, a flame retardant layer is provided on the inner wall of the fireproof outer shell.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. A capacitor with fireproof function is used in combination with a fireproof shell, a storage box, a liquid storage cavity, a compression pump, a liquid extraction pipe and a liquid discharge pipe. When a fire occurs in the capacitor body, smoke is detected by a smoke sensor, and then the compression pump is controlled to start. After the compression pump is started, the flame retardant liquid stored in the liquid storage cavity is extracted through the liquid extraction pipe, and then the flame retardant liquid is sent into the cavity between the base and the capacitor body through the liquid discharge pipe until the cavity is filled. In this way, the capacitor body can be flame-retarded and fire-extinguished, thereby achieving the purpose of facilitating fire prevention.

[0016] 2. The capacitor with fireproof function is used in combination with a rectifier plate, a straight tube, an air hole, an elbow and a liquid storage chamber. While conveying the flame retardant liquid, the flame retardant liquid flows downward through the guide of the rectifier plate, and the smoke and high-temperature fire generated by the fire rise along the rectifier plate. In this way, the flame retardant liquid can extinguish the fire point in advance during the circulation of the flame retardant liquid on the rectifier plate. The high-temperature gas at the bottom of the fireproof shell and the cavity of the capacitor body rises and is poured into the air hole outside the straight tube, and then flows into the liquid storage chamber through the elbow. In this way, the liquid storage chamber can be further pressurized, so that the speed of the flame retardant liquid sprayed out of the liquid outlet pipe is increased, thereby improving the fire extinguishing efficiency.
