Problems solved by technology

When the output DC voltage of this type of silicon rectifier is higher than 600 volts, the air humidity will increase due to the pure water flowing inside, resulting in a decrease in the insulation level of the material. The insulating material in the rectifier is prone to voltage breakdown and silicon eleme...

Abstract

A high-power electric-arc-explosion-preventing rectifier is disclosed. The rectifier comprises a sealing steel shell, an alternating current wire-inlet copper bar, a current-sharing connecting copper bar, an overvoltage absorption protection apparatus, a high-power silicon element, a high-speed fuse and a direct current wire-outlet copper bar, wherein the high-speed fuse is connected with the high-power silicon element in series to form a rectifying assembly, and the rectifying assembly is mounted in the sealing steel shell; each rectifying assembly is connected with the alternating current wire-inlet copper bar and the direct current wire-outlet copper bar separately through the current-sharing connecting copper bar; the sealing steel shell is full of transformer oil; a transformer oil insulating online detector is mounted on the sealing steel shell and immersed in the transformer oil; the sealing steel shell is equipped with a pressure relief valve; and a cooler is connected with the inner cavity of the sealing steel shell through an oil inlet/outlet connecting pipe. The high-power electric-arc-explosion-preventing rectifier provided by the invention is creative in design, high in insulation, compact in structure, simple and convenient to mount, small in occupied space, and capable of greatly improving the insulation property, the antifouling property and the thermal dissipation property, eliminating electric arc explosion accidents of the rectifier, and ensuring the safe and reliable operation of the overall power supply.
