Large efficient cooling explosion-proof capacitor

Abstract

The invention relates to a large efficient cooling explosion-proof capacitor, and the capacitor comprises a shell, a core body, an anode lead and a cathode lead; the anode lead and the cathode lead are connected to the core body; a pressure relief opening is formed in the shell, and the pressure relief opening is covered with an explosion-proof piece; a cooling pipe is arranged at the center of the core body in the axial direction in a penetrating mode, and a cooling circulating pump containing cooling liquid is arranged on the outer wall of the shell; the two ends of the cooling pipe are communicated with the cooling circulating pump, the water inlet end of the cooling pipe is communicated with a cooling ring pipe, the cooling ring pipe is spirally arranged around the core body and attached to the core body, the other end of the cooling ring pipe is communicated with the water outlet end of the cooling pipe, the cooling circulating pump is connected with an anode connecting wire and a cathode connecting wire, and the anode connecting wire is connected with the anode lead; and the cathode connecting line is connected with the cathode lead. According to the invention, the temperature rise of the core body is pre-controlled in a cooling manner, and the emergency pressure release of the explosion-proof sheet is combined, so that the possibility of high-temperature expansion of the core body is reduced on the premise of ensuring the safety, and the possibility of damage to the capacitor is further reduced.

Description

technical field [0001] The present application relates to the field of large-scale capacitors, in particular to a large-scale high-efficiency cooling explosion-proof capacitor. Background technique [0002] Capacitors are common energy storage components in electronic and electrical equipment, and play an important role in tuning, bypassing, coupling, filtering and other circuits. Capacitors are composed of two metal electrodes with a layer of insulating dielectric sandwiched between them. When a voltage is applied across the electrodes, charge is stored on the electrodes. 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, and the basic unit of the capacitance of a capacitor is Farad (F). [0003] With the development of metallized film capacitors, the capacity and volume of capacitors are getting larger and larger, and there are more and more applications for large capacitors...
