Description

Technical Field

[0001] The utility model relates to the technical field of capacitors, in particular to an intelligent capacitor. Background Art

[0002] Capacitors are components that store electricity and energy, and smart capacitors have added intelligent measurement and control units. They are smaller in size, lower in power consumption, cheaper, more cost-saving, more flexible to use, easier to maintain, longer in service life, and more reliable, meeting the higher requirements of modern power grids for reactive power compensation. There are still unreasonable aspects in the structure of existing smart capacitors: during use, the wiring terminals of existing smart capacitors will become loose and detached when pulled by external forces, which will cause the device to no longer work normally. This undoubtedly poses certain safety hazards, increases the risk of device failure, and causes many inconveniences to the staff.

[0003] In addition, existing smart capacitors are usually placed on the ground when not connected to the power system. When the ground becomes moist due to environmental changes, the bottom of the capacitor body is in direct contact with the ground. Over time, the bottom of the capacitor is prone to rust and damage, affecting the subsequent normal use of the capacitor and being detrimental to the long-term preservation of the capacitor.
