AI Technical Summary

Technical Problem

When existing integrated power capacitors are installed in the open or semi-open air, the top terminals are easily corroded by rain and dust, resulting in reduced insulation performance, difficulty in dissipating heat, inaccurate wiring, and cumbersome maintenance.

Method used

The capacitor box features a closed structure, equipped with insulating sleeves and outgoing terminals. The top surface has a removable protective cover, which includes a rectangular outer frame, an exhaust fan, an intake fan, a short tube, and a rubber short tube. Combined with a removable locking structure, it achieves sunshade, heat dissipation, precise wiring, and convenient maintenance.

Benefits of technology

It effectively protects the outgoing terminals from environmental corrosion, dissipates heat quickly, ensures stable operation of the capacitor, simplifies the wiring process, and reduces maintenance costs.

Abstract

The utility model discloses a novel collection formula power capacitor relates to the field of power electronics, and this capacitor includes the closed type capacitor box, and the box top surface evenly assembles insulating sleeve and the outgoing line terminal, and the four corners are equipped with hexagon bolt, and the detachable assembly protective cover, the box bottom surface is equipped with metal support foot, and the front and back surface and both sides are equipped with no. The protective cover contains rectangular outer frame, air outlet fan, air inlet fan, short cylinder, rubber short cylinder, mounting piece, top cover, rectangular rubber frame and limiting bolt. Rectangular outer frame is locked with the box through hexagon bolt, and air outlet fan and air inlet fan form one -way heat dissipation air duct, and short cylinder and outgoing line terminal one -to -one corresponding cable are set up, and rubber short cylinder seals and fixes cable, and top cover is locked with mounting piece through limiting bolt, and rectangular rubber frame seals gap. The capacitor can isolate the outside harm, strengthen heat dissipation, and the auxiliary wiring is convenient to dismount, and the operation stability and service life are improved.
