Problems solved by technology

However, the aluminum-plated metallized film is easily oxidized in the air to form a dense oxide layer with aluminum oxide as the main component. Although this oxide layer can prevent the metallized film from being oxidized further, when working under AC high voltage and high current, the The oxide layer will cause the capacity of the capacitor to drop rapidly

Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0029] The metallized film processing technology for rail transit locomotives comprises the following steps:

[0030] Step 1. Insulation base film pretreatment

[0031] Spray shielding oil to the surface of the first printing roller, and form the first oil layer 2 by the first printing roller with the shielding oil printed on the working surface of the insulating base film 1 to be processed, as figure 1 As shown; wherein, the first oil layer 2 is provided with rectangular blank processing areas 21 distributed in an array, and the surface of the first printing roller is provided with a relief patte...

Abstract

The invention relates to a metalized film used for a rail transit locomotive and a processing technology thereof. The processing technology comprises the steps of insulation basal film pretreatment, primary evaporation for preparing an aluminum coated layer, insulation basal film secondary treatment and performing secondary evaporation on the aluminum coated layer for composite preparing a tin coated layer. Oxidation of the aluminum coated layer can be effectively prevented by the tin coated layer, and sharp declining of the capacity of the capacitor does not occur in working under the AC high voltage and high current. The subsequent capacity of the capacitor does not influenced even insulation defects exist on the insulation basal film; and continuous breakdown of the multilayer insulation basal film does not occur in case of self-healing so that the phenomenon of large-area burning can be avoided. Therefore, the capacitor prepared by coiling of the metalized film can be massively applied to the rail transit locomotive to act as the energy storage component.

Description

technical field [0001] The invention relates to a metallized film for rail transit locomotives and a processing technology thereof, belonging to the technical field of capacitors. Background technique [0002] Urban rail transit refers to a mode of transportation with the characteristics of large volume, high speed, safety, punctuality, environmental protection, energy saving and land use, including subway, light rail, maglev, express rail, tram, new transportation system, etc. Therefore, the comprehensive utilization of new energy in the field of urban rail transit technology has also become the development demand of future urban rail transit. In the Chinese national standard "Common Terminology of Urban Public Transportation", urban rail transit is defined as "the general term for fast and large-capacity public transportation that is usually powered by electric energy and adopts wheel-rail operation." [0003] In rail transit locomotives, it is usually necessary to use AC...
