Do you want to know what ceramic dielectric materials are available? And the basic characteristics of ceramic dielectric capacitors? 🌻Ceramic dielectric materials for ceramic capacitors are generally divided into three categories. ✨Class Ⅰ ceramic dielectric material, Class Ⅱ ceramic dielectric material, Class Ⅲ ceramic dielectric material, do you know the difference between them? How to choose [...]
Reasons for the burning of the starting capacitor A single-phase motor with a slightly larger power is generally equipped with two capacitors, namely the starter and the running capacitor. Before 70 years, single-phase motors were mostly a capacitor, which is a starting capacitor. After the motor is started, the capacitor is thrown off by the centrifugal [...]
Capacitor circuit characteristics 👉Traditional dielectric capacitors, supercapacitors and chemical batteries are all energy storage electronic devices, all of which have the function of storing electrical energy. The charge on the capacitor is the integral of the charging current "i" to the time "t", as shown in the following formula: 🌞Q=∫idt (Formula 1) According to the formula, [...]
What happens when AC power is applied to the capacitor? Capacitors behave differently from resistors-in resistors, the flow of electrons is proportional to the voltage drop; in capacitors, when it is charged or discharged to a new voltage level, it resists changes in voltage by absorbing or releasing current . When providing direct current (DC) to [...]
power supply-1. If the electrolytic capacitors is not dehydrated, the leakage current will increase. The influence of the electrolytic capacitor with increased leakage current on the power supply: At the input of the power supply, there will be no-load power consumption When used for IC startup, the startup time will be extended When the leakage current [...]
An individual can form its own unique operating system, and multiple structures together can form the entire electrical operation process. The core component is the capacitor. Although the proportion of other parts is not as good as the capacitor, the individual is indispensable, so it is probably Summarize the composition and function of the various factors [...]
How to measure the quality of high voltage capacitors Everyone knows that the voltages of high voltage capacitors are 1KV, 2KV, 3KV, etc. Recently, I have seen a small partner suggest how to judge the quality of their 10KV high-voltage capacitors. In fact, the method is very simple. I hope it can also help novices to [...]
Why can't the Y capacitor capacity be too large? Y capacitors are capacitors that are respectively connected between the two lines of the power line and the ground (LE, NE). The medium is ceramic, which is a type of ceramic capacitor. Y capacitors are different from high-voltage ceramic capacitors. Y capacitors are safety capacitors. After failure, it [...]
Y capacitors are safety capacitors. This type of capacitor meets safety standards and has passed safety standards testing/certification. Therefore, even if this type of capacitor fails, it will not cause electric shock and will not endanger personal safety. In addition, it is made of flame-retardant materials and only It produces explosions, no sparks, only gas. The [...]
What is capacitance compensation Capacitance compensation is reactive power compensation or power factor compensation. The electrical equipment of the power system generates reactive power when in use, and it is usually inductive, which will reduce the efficiency of the power supply capacity, which can be improved by appropriately adding capacitance in the system. Power capacitor compensation [...]
