薄膜电容器可分为直流薄膜电容器和交流薄膜电容器两大类:
直流薄膜容器是指工作在以直流电源供电的电路中的薄膜容器
,可分为通用类、抑制电源电磁干扰类、脉冲类和精密类四类;交
流薄膜容器是指工作在以交流电源供电的电路中的薄膜电容器,
按功能分电动机启动运行、功率因素补偿等。
特点:
1.它具有充放电特性和阻止直流电流通过,允许交流电流通过的能力。
2.在充电和放电过程中,两极板上的电荷有积累过程,也即电压有建立过程,因此,
电压不能突变。
充电:两板分别带等量异种电荷,每个极板带电量的绝对值叫带电量。
放电:两极正负电荷通过导线中和。在放电过程中导线上有短暂的电流产生。
3.容抗与频率、容量之间成反比。即分析容抗大小时就得联系信号的频率高低、
容量大小 。
Thin film capacitors can be divided into two categories: DC film capacitors
and AC film capacitors.DC film capacitors refer to thin film capacitors operating
in DC power supply circuits.It can be divided into four categories: general purpose,
electromagnetic interference suppression, pulse type and precision class.A thin film
capacitor is a thin film capacitor operated in an AC power supply circuit.According
to function, the motor starts operation and power factor compensation.
Characteristic:
1. it has charge and discharge characteristics and prevents DC current passing,
allowing AC current to pass through.
2. during charging and discharging, the charge on the two plate is accumulated,
that is, the voltage is established.
The voltage on the capacitor can not be mutated.
Charging of capacitors: two plates are charged with the same amount of dissimilar
charges. The absolute value of the charged capacity of each plate is called the
capacitor band.
Electricity.
Discharge of capacitors: the positive and negative charges of capacitors are neutralized
through wires. There is a short passage on the wire during the discharge.
The current is produced.
The capacitance of 3. capacitors is inversely proportional to the frequency and capacity.
That is to say, when analyzing capacitance reactance, the frequency of signal must be
contacted.High and low, capacity size.
