ABB電容器（簡稱電容）是組成電子電路的主要元件。它可以儲存電能，具有充電、放電及通交流、隔直流的特性。電容器是由兩個相互靠近的金屬電極板，中間夾一層絕緣介質(zhì)構(gòu)成的。在電容器的兩個電極加上電壓時，電容器就能儲存電能。 ABB capacitor (referred to as capacitor) is the main component of the electronic circuit. It can store electrical energy, and has the characteristics of charging, discharging and communicating with AC and dc. The capacitor is made up of two metal electrode plates which are close to each other and are sandwiched with an insulating medium. When a voltage is applied to the two electrodes of the capacitor, the capacitor can store electrical energy. CLMD43/20KVAR 400V 50HZ電容器結(jié)構(gòu)： Capacitor structure:
1．電容器 1. capacitor(1)電容器：兩塊相互靠近又彼此絕緣的導(dǎo)體組成電容器．電容器可以儲存容納電荷． (2)電容器的帶電量：一個極板所帶電量的絕對值． (1) capacitor: two capacitors that are close to each other and insulated from each other. The capacitor can store and hold the charge. (2) the charge of the capacitor: the absolute value of the electric charge of a plate (3)電容器的充、放電： (3) charge and discharge of capacitor: ①充電：使電容器帶電的過程稱為充電，充電后兩板帶等量異種電荷． Charging: the process of charging the capacitor is called charging. After charging, the two plates have the same amount of dissimilar charge ②放電：使充電后的電容器失去電荷叫放電． Discharge: the charge of the charged capacitor is called discharge 2．電容： 2. capacitor: (1)定義：電容器所帶的電量與兩極板間電勢差的比值叫電容．定義式： (1) definition: ratio with capacitor charge and electric potential difference between the two electrode capacitance. The definition of call: (2)物理意義：電容是描述電容器儲存電荷本領(lǐng)大小的物理量，在數(shù)值上等于把電容器兩極板間的電勢差增加1 V所需充加的電量． (2) physical meaning is described: capacitor capacitor charge power physical size, equal in value to the potential difference between the plates of the capacitor two is increased by 1 V required charging power. 注意：電容C由電容器本身的構(gòu)造因素決定，與Q、U無關(guān)． Note: the capacitor C is determined by the structure of the capacitor itself and is independent of Q and U (3)電容的單位：法．符號F． 1 F=106 μF=1012pF (3) unit of capacitance: method. Symbols F.1, F=106, F=1012pF 3．平行板電容器的電容C：與平行板正對面積S、電介質(zhì)的介電常數(shù)ε成正比，與極板間的距離d成反比． The capacitance C of 3. parallel plate capacitor is proportional to the area of the parallel plate to the area of S and the dielectric constant of the dielectric, and is inversely proportional to the distance d between the plates 平行板電容器電容的公式：C= ． Formulas for capacitance of parallel plate capacitors: C=. 式中k為靜電力恒量．此式為平行板電容器的決定式，不難看出，電容器的電容大小是由電容器本身的特性決定的．電容是描述電容器的特性的物理量，與電容器帶電多少、帶不帶電荷無關(guān)． Where k is the static power constant. This type of parallel plate capacitor type decision, is not difficult to see that the capacitance of capacitor is determined by the characteristics of the capacitor itself. The capacitance is a physical quantity describing characteristics of the capacitor, capacitor, and many charged with or without charge. 4．常用電容器：從構(gòu)造上看，可分為固定電容器和可變電容器兩類． 4. commonly used capacitors: from a structural point of view, can be divided into fixed capacitors and variable capacitor two categories 固定電容器的電容是固定不變的；可變電容器一般是通過改變兩極的正對面積來改變電容．當(dāng)然也可以通過改變兩極間的距離、或者改變電容器所充的電介質(zhì)來改變電容． The fixed capacitor capacitor is fixed; the variable capacitor is by changing the polar opposite area to change the capacitance. Of course you can change the distance between the two poles, or the change of filling dielectric capacitor to change the capacitance. 5．電容器的額定電壓和擊穿電壓：擊穿電壓是電容器的極限電壓，超過這個電壓，電容器內(nèi)的介質(zhì)將被擊穿．額定電壓是電容器長期工作時所能承受的電壓，它比擊穿電壓要低．電容器在不高于額定電壓下工作都是安全可靠的，不要誤認為電容器只有在額定電壓下工作才是正常的． The 5. capacitor rated voltage and breakdown voltage, breakdown voltage is the voltage of the capacitor exceeds the limit, the voltage, capacitor in the medium will be breakdown. The rated voltage is the voltage of capacitor can withstand long-term work, it is to lower the breakdown voltage of capacitor voltage is not higher than that. In the work are safe reliable fixed, not that of the capacitor only work under rated voltage is normal. 電容器具有“通交流、隔直流”的特性。直流電的極性和電壓大小是固定不變的，不能通過電容器。而交流電的極性和電壓的大小是不斷變化的，能使電容器不斷地充電與放電，形成充、放電電流。 The capacitor has the characteristics of through AC and DC isolation. The polarity and voltage of the direct current are fixed and cannot be passed through the capacitor. The polarity of the alternating current and the size of the voltage are constantly changing, can make the capacitor constantly charging and discharging, forming charging and discharging current.
CLMD43/20KVAR 400V 50HZ電容器作用： Capacitor action:電容器廣泛應(yīng)用在各種高、低頻電路和電源電路中，起退耦（指消除或減輕兩個以上電路間在某方面相互影響的方法）、耦合（將兩個或兩個以上的電路連接起來并使之相互影響的方法）濾波（濾除干擾信號、雜波等）、旁路（與某元器件或某電路相并聯(lián)，其中某一端接地）、諧振（指與電感并聯(lián)或串聯(lián)后，其振蕩頻率與輸入頻率相同是產(chǎn)生的現(xiàn)象。例如，調(diào)諧選擇電臺頻率）、降壓、定時等作用。 Capacitors are widely used in all kinds of high and low frequency circuit and power supply circuit, which decoupling (refers to eliminate or affect each other in certain aspects of the method to reduce more than two circuits) and coupling (method of interaction will be two or more than two connecting circuit and make the filter to filter out the interference signal, () clutter), bypass (in parallel with a component or a circuit in which one end grounded), resonance (referring to the inductance in series or in parallel, the oscillation frequency and the input frequency is the same phenomenon. For example, tuning selects radio frequency), buck, timing, and so on. 低壓電容器 - CLMD型號 CLMD13/10KVAR 400V 50HZ CLMD13/15KVAR 400V 50HZ CLMD43/15KVAR 400V 50HZ CLMD43/20KVAR 400V 50HZ CLMD43/25KVAR 400V 50HZ CLMD43/30KVAR 400V 50HZ CLMD53/30KVAR 400V 50HZ CLMD53/40KVAR 400V 50HZ CLMD53/45KVAR 400V 50HZ CLMD53/50KVAR 400V 50HZ CLMD63/60KVAR 400V 50HZ CLMD63/70KVAR 400V 50HZ CLMD63/80KVAR 400V 50HZ CLMD83/100KVAR 400V 50HZ
