Problems solved by technology

[0002] Capacitor is a device that holds charge. Before the core body of the polypropylene film capacitor is gold-sprayed, in order to prevent the metal dust generated during the gold-spraying process from entering the interior of the mandrel lumen and causing an internal short circuit of the mandrel, it is necessary to Insert dust-proof plugs into the round holes at both ends. At present, the known dust-proof plugs are a kind of hollow cap-shaped rubber parts, which are easily deformed and not durable. As a result, there will still be some metal dust entering the inside of the mandrel lumen

Abstract

The invention discloses an inflatable dustproof plug for a capacitor core. The inflatable dustproof plug comprises an inflatable plug body and a plug cap which are fixed into a whole, the plug cap is provided with an inflation valve and a display screen, the plug cap is internally provided with a controller which is connected with the display screen through a line, and a pressure sensor is connected to the lower portion of the controller through a line. The dustproof plug is safe and durable and can be highly attached to the inner wall of a mandrel, no gap is left, and the dustproof effect is guaranteed;furthermore, the inflatable dustproof plug can be repeatedly used, and expenditure is reduced for enterprises.

Description

technical field [0001] The invention relates to the technical field of capacitor accessories, in particular to an air-filled dustproof plug for a capacitor core. Background technique [0002] Capacitor is a device that holds charge. Before the core body of the polypropylene film capacitor is gold-sprayed, in order to prevent the metal dust generated during the gold-spraying process from entering the interior of the mandrel lumen and causing an internal short circuit of the mandrel, it is necessary to Insert dust-proof plugs into the round holes at both ends. At present, the known dust-proof plugs are a kind of hollow cap-shaped rubber parts, which are easily deformed and not durable. As a result, there will still be some metal dust entering the inside of the mandrel lumen. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an air-filled dust-proof plug for capacitor cores. The dust-proof plug is safe and durable. ...
