Abstract

The invention discloses an intelligent low-voltage power capacitor based on a dry capacitor, which includes a casing, heat dissipation grids are evenly arranged on both sides of the casing, and external terminals are arranged on the upper end surface of the casing through an outer cover plate. The inner cavity of the outer shell is symmetrically arranged with an inner shell, and the inner cavity of the inner shell is connected with a dry capacitor through a mounting seat, and the mounting ears are symmetrically arranged on both sides of the inner shell. The end surface is provided with an inner cover plate, the upper end surface of the inner cover plate is provided with an internal terminal, and the lower end of the internal terminal is electrically connected to the upper end of the dry capacitor through an internal wire. The present invention relates to the technical field of capacitors. The intelligent low-voltage power capacitor based on dry capacitor solves the problem of insufficient heat dissipation performance of multiple groups of capacitors in the existing low-voltage power capacitor box. The problem of messy wiring.

Description

An intelligent low-voltage power capacitor based on dry capacitor technical field The present invention relates to capacitor technical field, be specifically a kind of intelligent low-voltage power capacitor based on dry capacitor device. Background technique The coating of existing self-healing high and low voltage capacitor elements is mostly zinc-aluminum film, silver-zinc film or silver-zinc-aluminum Membranes, such components are resin-sealed dry-type or wax-dipped dry-type structures when such components are made into capacitors, resin-sealed dry-type structures exist The problem is that the energy generated by the component body and the energy generated by the component self-healing during the operation of the capacitor are conducted outward through the resin. Not ideal, the solid resin is easy to burst, the dispersion of the inner fuse is large, the protection effect is not ideal, and the protection method is single; The problem with the wax-dipped dry stru...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides an intelligent low-voltage power capacitor based on dry capacitors, which solves the insufficient heat dissipation performance of multiple sets of capacitors in the existing low-voltage power capacitor box, and at the same time is prone to pull-out during the capacitor protection process. The arc is too long, the positioning and installation of the capacitor is inconvenient, and the internal wiring of the capacitor is messy.
