Abstract

A fire-proof high-voltage alternating current capacitor is disclosed, including a housing, a cover, two terminals, leads, insulating sleeves and cores. Each terminal includes a tapered front end; theinsulating sleeves comprise an upper insulating sleeve and a lower insulating sleeve, the cores connected in parallel via leads are arranged in the upper insulating sleeve and the lower insulating sleeve in parallel, the tail end of the last core in the parallel cores in the upper insulation sleeve and the head end of the first core arranged in the parallel cores in the lower insulation sleeve areconnected through the insulating sleeves through leads, the head end of the last core in the parallel cores in the upper insulating sleeve and the tail end of the first corein the parallel cores in the lower insulating sleeve are respectively connected to the tapered front ends of the two terminals through leads, and the tapered front ends are fixedly connected with the leads and the leads are fixedly connected to the terminals of the cores through a tin spot welding method. The capacitor has the characteristics of large capacity, small heat generation, explosion protection and the like. Thedesign of tapered front ends reduces a welding contact surface and heat generation, and the method of tin spot welding also reduces heat generation of the capacitor.

Description

technical field [0001] The invention relates to a capacitor device, and more particularly to a flame-proof high-voltage AC capacitor. Background technique [0002] At present, there are many capacitors on the market, but there are also many shortcomings and safety hazards, such as high temperature during welding, high impact strength, and damage to the capacitor cover. When the temperature of the capacitor is too high during operation, it is easy to cause an explosion, and the circuit burns, causing a safety hazard. Contents of the invention [0003] The technical problem to be solved by the invention lies in the problem that the existing capacitor has small capacity, high heat generation and easy failure. [0004] The present invention solves the above-mentioned technical problems through the following technical solutions: a flame-proof high-voltage AC capacitor, including a shell, a cover, two connection terminals, a lead wire, an insulating sleeve, a core, an explosion...
