Embodiment 1

[0031] Embodiment one (see Fig. 1):

[0032] This example is a capacitor with a parallel connection inside the core, as shown in the figure: the capacitor is wound into a capacitor core through a layer of metallized polyester film 1 and a layer of metallized polypropylene film 2 in parallel, and the metallized polyester film The thicknesses of the film 1 and the metallized polypropylene film 2 can be matched in different thicknesses, so as to achieve the best matching of capacity stability at different temperatures.

[0033] The internal shunt capacitor process steps are:

[0034] 1. Use a winding machine to wind a layer of metallized polypropylene film and a layer of metallized polyester film into a capacitor core. The thickness of the film material can be selected and proportioned according to actual needs;

[0035] 2. Flatten the capacitor core and place it on the cold-press fixture, and set the surface pressure of the core to 1.20~1.40kg / mm 2 , pressurize the core for 5 ...

Embodiment 2

[0043] Embodiment two (see Fig. 2):

[0044] This example is a capacitor with external parallel connection of the core, as shown in the figure: the capacitor is externally connected in parallel through a core 3 wound by a metallized polyester film and a core 4 wound by a metallized polypropylene film. Capacitors, the capacities of the two capacitor cores can be freely matched, so as to achieve the best match of capacity stability at different temperatures.

[0045] External shunt capacitor process steps:

[0046] 1. Use a winding machine to wind two layers of metallized polypropylene film into a capacitor core, and wind two layers of metallized polyester film into a capacitor core. The core capacity is wound according to the pre-designed ratio;

[0047] 2. After flattening the capacitor cores, place them on the cold pressing fixture respectively, and set the surface pressure of the cores to 1.20~1.40kg / mm 2 , pressurize the core for 5 minutes, then put the metallized polypr...

Abstract

This invention relates to a compound dielectric capacitor, in which, its main body is a core formed by a metalized polymer film and a metalized polypropylene film and the capacitor is made by internal parallel winding and winding outer parallel method,which can solve the problem that the production process of PC, the main material of current metalized PC capacitors will pollute environment and stabilize the volume of capacitors under different temperatures.

Description

Technical field: [0001] The invention relates to an electrical component capacitor, in particular to a capacitor with good capacity and temperature stability and a manufacturing method thereof. Background technique: [0002] Among the various existing organic film capacitors, metallized polycarbonate capacitors have good temperature stability and can be widely used in important scientific and technological fields such as national defense and aviation. However, polycarbonate, the main material of the capacitor, is not only expensive, but also the production of polycarbonate will cause some pollution to the environment, and production has basically stopped at present. Therefore, there is an urgent need to invent a capacitor with the same good temperature stability. Invention content: [0003] The purpose of the present invention is to provide a capacitor with good capacity and temperature stability and its manufacturing method, which mainly solves the technical problem that...
