Analysis on the cause of power capacitors explosion damage In recent years, more and more power capacitors have been put into operation, but due to poor governance and other technical reasons, power capacitors are often damaged and exploded. The reasons are as follows: Breakdown of internal components of the capacitor: mainly caused by poor manufacturing process. [...]
Capacitors are components that store electricity and electrical energy (potential energy). the classification of capacitors is 10 categories. 1. The classification of capacitors is divided into three categories according to the structure: fixed capacitors, variable capacitors and trimmer capacitors. 2. Classified by electrolyte: organic dielectric capacitor, inorganic dielectric capacitor, electrolytic capacitor, electric heating capacitor and air [...]
Electrolytic capacitors are usually made of metal foil (aluminum/tantalum) as the positive electrode, and the insulating oxide layer of the metal foil (aluminum oxide/tantalum pentoxide) as the dielectric. Electrolytic capacitors are divided into aluminum electrolytic capacitors and tantalum electrolysis based on their positive electrodes. Capacitors. The negative electrode of an aluminum electrolytic capacitor is composed of [...]
Capacitors are the key components for starting air-conditioning motors. Most air conditioners on the market today use capacitors to integrate air-conditioning and operation.What is the function and principle of air conditioner capacitors in air conditioner?The following is an introduction to the functions and principles of air conditioning capacitors. The role of air conditioning capacitors Capacitors are the [...]
Polyester capacitors is also called CL11 (PEI) capacitor, which is vacuum encapsulated with epoxy resin, which improves the mechanical strength and moisture resistance of the product, has good stability, high reliability, high insulation resistance, small loss, small size and light weight , Low price, widely used in the DC and pulse circuits of TV sets, tape [...]
Tantalum capacitor, full name is tantalum electrolytic capacitor .It is a kind of electrolytic capacitor. It uses metal tantalum as a medium. Unlike ordinary electrolytic capacitors, it uses electrolyte. Therefore, it is suitable for working at high temperatures. It is a small-capacity product in a capacitor that can achieve a large capacitance.The following describes the advantages,disadvantages [...]
SMD capacitor is a kind of capacitor material. The full name of chip capacitors is: multilayer (laminated, stacked) chip ceramic capacitors, also known as chip capacitors and chip capacitors. There are two ways to express chip capacitors, one is expressed in inches and the other is expressed in millimeters. Chip capacitors The chip multilayer ceramic dielectric [...]
The application of film capacitors is mainly in electronics, home appliances, communications, power, electrified railways, hybrid vehicles, wind power generation, solar power generation and other industries. The stable development of these industries has promoted the growth of the film capacitor market. The application of film capacitors is also included in the cross-linking of analog signals, the [...]
Solid capacitor full name solid aluminum electrolytic capacitor, the difference between solid capacitors and electrolytic capacitors is mainly the following points： 1. Different dielectric materials are used. The liquid aluminum capacitor dielectric material is electrolyte, while the solid capacitor dielectric material is conductive polymer. 2. Overheating of the electrolytic capacitor will cause the electrolyte to expand [...]
Ceramic capacitor are also called porcelain dielectric capacitors or monolithic capacitors. As the name implies, porcelain dielectric capacitors are capacitors whose dielectric material is ceramic. According to different ceramic materials, it can be divided into two types: low-frequency ceramic capacitor and high-frequency ceramic capacitors. According to the structure, it can be divided into wafer capacitors, tubular [...]
