Description

Technical Field

[0001] This utility model relates to the field of intelligent capacitor technology, specifically to a Type 95 intelligent capacitor. Background Technology

[0002] Intelligent capacitors are power devices that integrate advanced technologies such as modern measurement and control, power electronics, network communication, and automatic control. They are mainly used for low-voltage reactive power compensation.

[0003] Intelligent capacitors have revolutionized traditional reactive power compensation devices by replacing outdated controller technology and the use of mechanical contactors or electromechanical switches for capacitor switching, thus meeting the higher requirements of modern power grids for reactive power compensation. Intelligent capacitors primarily consist of high-quality capacitors, reactors, intelligent measurement and control modules, switching modules, line protection modules, and human-machine interface modules. They are widely used in factory power distribution systems, residential power distribution systems, municipal and commercial building power distribution systems, traffic tunnel power distribution systems, as well as in prefabricated substations, switchgear, and outdoor distribution boxes.

[0004] However, the existing Type 95 intelligent capacitor has structural shortcomings: the internal component placement is unreasonable, resulting in a large size and high manufacturing cost. Furthermore, the placement of the heat dissipation holes at the top of the capacitor allows dust to easily enter, accumulating inside and affecting heat dissipation, leading to overheating and impacting its lifespan and performance. In addition, dust can reduce the capacitor's insulation level, increasing the risk of electrical breakdown and even causing short circuits or malfunctions, posing safety hazards.
