Embodiment 1

[0033] Embodiment one (see figure 1 ):

[0034] 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.

[0035] The internal shunt capacitor process steps are:

[0036] 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;

[0037] 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 fo...

Embodiment 2

[0045] Embodiment two (see figure 2 ):

[0046] 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.

[0047] External shunt capacitor process steps:

[0048] 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;

[0049] 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 p...

Abstract

The invention relates to a capacitor of an electric element, in particular to a method for manufacturing a capacitor in parallel connection outside a core. The capacitor is a composite dielectric capacitor, and the main component of the capacitor is a capacitor core formed by a metallized polyester film and a metallized polypropylene film. The capacitor can be manufactured by a method of winding an external part in parallel connection. The method mainly solves the technical problems that the production process of a main body material polycarbonate of the conventional metallized polycarbonate capacitor can cause certain pollution to the environment; besides, the method ensures that the capability of the capacitor is more stable at different temperatures, and greatly reduces the cost.

Description

[0001] This application is a divisional application of invention patent application 200610023957.3 (application date: February 17, 2006, name: a capacitor with good capacity and temperature stability and its manufacturing method). Technical field: [0002] The invention relates to an electrical component capacitor, in particular to a method for making a capacitor connected in parallel outside the core. Background technique: [0003] 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. I...
