Metallized polypropylene film capacitor

Abstract

The invention discloses a metallized polypropylene film capacitor. Themetallized polypropylene film capacitor structurally comprises a wiring terminal, a closing cover, an equipment box and a mountingbracket. A damping vibration isolation layer is arranged on the surface of the vibration isolation block of the metallized polypropylene film capacitor, and the vibration of equipment is reduced through a vibration isolation method; the long-strip shaft of an overturning block separates the wall of the equipment from the vibration isolation block by a certain distance to prevent the acting forceof vibration from being directly transmitted to the vibration isolation block, and an arc-shaped spring shaft is connected to the included angle of the long-strip shaft of the overturning block, so that when the equipment vibrates, one part of the acting force of vibration is transmitted to the long-strip shaft of the overturning block; and the wall body connected between the pieces of equipment can press the overturning block backwards, the spring shaft is arranged on the included angle of the long-strip shaft, a spring has the springback characteristic and forms counter-acting force with theoverturning extrusion force of the long-strip shaft, energy generated by vibration can be consumed in the mutual abutting and buckling movement of component force of the equipment, and the vibrationreduction effect is achieved.

Description

technical field [0001] The invention relates to the field of capacitors, in particular to a metallized polypropylene film capacitor. Background technique [0002] Metallized polypropylene film has become one of the main materials for capacitors. Metallized polypropylene film has the characteristics of low loss, good stability, high volume resistivity, and small thermal shrinkage. Therefore, metallized polypropylene film is used in electric power Widely used in equipment capacitors; [0003] In the existing society, when metallized polypropylene film capacitors are installed on large-scale power equipment, the space for metallized polypropylene film capacitors that can be installed is limited, and it is impossible to install shock absorbers on the capacitor's installation site, while The larger the power equipment, the greater the impact of its own gravity and structure. The power equipment will vibrate when it is working, and the capacitor will run in a long-term vibration ...

Problems solved by technology

[0003] In the existing society, when metallized polypropylene film capacitors are installed on large-scale power equipment, the space for metallized polypropylene film capacitors that can be installed is limited, and it is impossible to install shock absorbers on the capacitor's installation site, while The larger the power equipment, the greater the impact of its own gravity and structure. The power equipment will vibrate when it is working, and the capacitor will run in a long-term vibration environment, which will cause problems such as loosening of the internal parts of the capacitor and damage the capacitor.
