Problems solved by technology

Due to the limitations of its realization principle, AC capacitors will generate heat and overburn due to overload and aging of the wiring under the conditions of overvoltage, overcurrent, high ambient temperature, material aging, and material defects, etc., and the overheating temperature will slow down. Slow lead to the inside of the capacitor, causing the capacitor to catch fire, explode and other accidents, resulting in fire of home appliances, causing loss of life and property to users
Moreover, in long-term use, when the pins are aging and fractured, the entire capacitor is generally replaced, but the capacitor itself has not failed, so unnecessary waste is generated.

Abstract

The invention relates to the technical fields of capacitors, and in particular to a heat preservation material for a horn-shaped tube in a capacitor. The heat preservation material is prepared from the following raw materials (in percentage): 10 percent of cinerite, 10 percent of polyvinyl alcohol, 10 percent of water, 15 percent of hydrophobic resin, 15 percent of methyl cellulose, 5 percent of bis(2,2,6,6-tetramethyl-4-piperidyl)sebate, 5 percent of gamma-glycidoxypropyltrimethoxysilane, 5 percent of polyethylene vinyl acetate, 5 percent of pitchstone glass beads, 5 percent of ethylene-acrylate-glycidyl methacrylate copolymer, 5 percent of antigorite powder and 10 percent of modified composite fiber. The heat preservation material disclosed by the invention is extremely low in heat conductivity and good in adhesion, the heat preservation material is not easy to fall off after being painted on the surface of the horn-shaped tube, and cracks cannot be generated after long-term use.

Description

Technical field: [0001] The invention relates to the technical field of capacitors, in particular to a thermal insulation material for horn tubes in capacitors. Background technique: [0002] Capacitors, commonly referred to as capacitors, are the most widely used electrical components in electronic equipment. They are widely used in DC blocking, coupling, bypass, filtering, tuning circuits, and energy conversion control in circuits. [0003] In the prior art, the capacitor is composed of a shell cover, a shell and a core body. Generally, terminal pins are drawn out from the shell cover for connecting to the circuit, but the pins of the capacitor are generally directly welded to the core body. Up. Due to the limitations of its realization principle, AC capacitors will generate heat and overburn due to overload and aging of the wiring under the conditions of overvoltage, overcurrent, high ambient temperature, material aging, and material defects, etc., and the overheating te...
