Abstract

The invention discloses a high voltage test mechanism used for producing a flat bridge, and mainly relates to the technical field of bridge rectifiers. The high voltage test mechanism comprises a double-switch cylinder, a lower electrode, an upper internal electrode, an upper external electrode, a high voltage test base, a high voltage test cylinder base, a high voltage test cylinder, a track and a material blocking cylinder. The double-switch cylinder and the material blocking cylinder are fixed at one side of the track. The track and the high voltage test cylinder base are fixed on a rack panel. The high voltage test base is installed at the lower end of the high voltage test cylinder. The upper internal electrode and the upper external electrode are installed on the high voltage test base in parallel. An insulating layer is arranged between the lower electrode and the track. The high voltage test mechanism is quite simple in overall structure and operation process, convenient and rapid in maintenance, low in cost, high in degree of automation and simple in manual operation and can guarantee long-time and high-efficiency stable testing. The invention also discloses a working method of the high voltage test mechanism used for producing the flat bridge.

Description

technical field [0001] The invention relates to the technical field of bridge rectifiers, in particular to a high-voltage testing mechanism for producing flat bridges and a working method of the high-voltage testing mechanism. Background technique [0002] The bridge rectifier is made of four rectifying silicon chips connected in a bridge type and packaged externally with insulating plastic. There are many types of bridge rectifiers: flat, round, square, bench-shaped (in-line and patch), etc., among which the flat bridge is a kind of bridge rectifier. [0003] In recent years, with the continuous development of science and technology, related industries have higher and higher technical requirements for flat bridges. However, the existing high-voltage testing institutions for the production of flat bridges still have the following defects: [0004] 1. The overall structure and operation process of the high-voltage testing mechanism are very complicated, and at the same tim...
