Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of capacitor film detection, specifically relates to a detection device of capacitor film. BACKGROUND

[0002] The metalized film capacitor is made of organic plastic film as the dielectric and metalized film as the electrode, and is made by winding (except for the laminated structure). The film used in the metalized film capacitor includes polyethylene, polypropylene, polycarbonate, etc. In order to ensure the stability of the metalized film capacitor during use, the organic plastic film needs to be detected in the production process.

[0003] The Chinese patent with the publication number CN222144916U and the name of a capacitor film shrinkage detection device includes a box body, a moving damping mechanism is arranged at the bottom of the box body, a heating mechanism is arranged at the inner side of the box body, a box door is arranged at one side of the box body, a fixing mechanism is arranged at one side of the box door, a clamping groove is formed at the inner side of the box body, and a placing groove is formed at the inner side of the bottom of the box body. In the utility model, the driving motor is started to drive the threaded rod to rotate. Since the placing groove limits the movement of the moving frame, the threaded rod drives the moving frame to move forward, thereby driving the placing frame to move forward, moving the placing frame to the outside of the box body, and facilitating the removal of the film in the placing frame, making the detection process safer and more efficient.
