A Locomotive Capacitor With Extrusion-Resistant, High Heat Dissipation Case

Abstract

The invention discloses a locomotive capacitor with an extrusion-resistant and high-heat dissipation shell. The locomotive capacitor comprises the shell and a cover plate, wherein the shell comprisesan inner shell and an outer shell, an upper end of the outer shell is flush with an upper end of the inner shell, and a sandwiched layer is arranged between the outer shell and the inner shell. The important key of the capacitor lies in that high-efficiency cooling performance is possessed, the dual-layer shell is arranged, the shells prop against each other by a reinforcement block to form the sandwiched layer, and the sandwiched layer is used for cooling; and in order to improve the cooling effect, an outer surface of the shell is processed to form cooling fins, meanwhile, an air ventilationhole and a cooling hole are formed in the sandwiched layer, a heat conduction pipe is further arranged between a core and the outer shell, and heat transferring is facilitated.

Problems solved by technology

[0003] Locomotive capacitors generally bear a large amount of electricity and generate a lot of heat. The service life of capacitors is often affected by the working environment. One of the biggest problems is temperature. The heating accelerates the aging of the internal components of the capacitor and shortens the service life. It is one of the problems that capacitor improvement has been committed to

Not only that, mechanical hard damage has also been one of the reasons for the shortened service life of capacitors in recent years. In high-light mechanical operations, accidents such as extrusion, friction and collision are prone to occur, resulting in deformation, damage and unstable fixation of the capacitor shell. , resulting in continuous work being affected. In the high-demand capacitor manufacturing field, the internal core deformation caused by the deformation of the capacitor shell alone will greatly reduce the function of the capacitor and affect the maximum function. Therefore, the protection of the capacitor shell It is also quite important; it will be a very difficult problem to solve the protection of the shell and the problem of heat dissipation at the same time
