              小型接觸器廣泛用作電力的開斷和控制電路

              來源:http://www.cekidots.com/ 日期:2021-06-11 發布人:tongjid

              ABB接觸器利用主接點來開閉電路,用輔助接點來執行控制指令。主接點一般只有常開接點,而輔助接點常有兩對具有常開和常閉功能的接點,小型的接觸器也經常作為中間繼電器配合主電路使用。

              ABB contactor uses main contact to open and close circuit and auxiliary contact to execute control command. The main contact usually has only normally open contact, while the auxiliary contact often has two pairs of normally open and normally closed contacts. Small contactors are often used as intermediate relays to cooperate with the main circuit.
              交流接觸器的接點,由銀鎢合金制成,具有良好的導電性和耐高溫燒蝕性。ABB小型接觸器的動作動力來源于交流電磁鐵,電磁鐵由兩個“山”字形的幼硅鋼片疊成,其中一個固定,在上面套上線圈,工作電壓有多種供選擇。為了使磁力穩定,鐵芯的吸合面,加上短路環。交流接觸器在失電后,依靠彈簧復位。
              The contact of AC contactor is made of silver tungsten alloy, which has good conductivity and high temperature ablation resistance. ABB small contactor is driven by AC electromagnet. The electromagnet is made up of two "mountain" shaped young silicon steel sheets, one of which is fixed and covered with coil. There are various working voltages to choose from. In order to stabilize the magnetic force, a short-circuit ring is added to the pull-in surface of the iron core. AC contactor in the power loss, rely on spring reset.
              另一半是活動鐵芯,構造和固定鐵芯一樣,用以帶動主接點和輔助接點的開短。20安培以上的接觸器加有滅弧罩,利用斷開電路時產生的電磁力,快速拉斷電弧,以保護接點。交流接觸器制作為一個整體,外形和性能也在不斷提高,但是功能始終不變。無論技術的發展到什么程度,普通的交流接觸器還是有其重要的地位。
              The other half is a movable iron core with the same structure as the fixed iron core, which is used to drive the opening and closing of the main contact and auxiliary contact. The contactors with more than 20 amperes are equipped with arc extinguishing cover. The electromagnetic force generated when the circuit is disconnected can quickly pull off the arc to protect the contact. AC contactor as a whole, shape and performance are constantly improving, but the function is always the same. No matter to what extent the technology develops, ordinary AC contactor still has its important position.
              小型接觸器其實就是一種短路保護器,廣泛用于配電系統喝控制系統,主要進行短路保護或嚴重過載保護。工作時,熔斷器串連在被保護的電路中。當電路發生短路或嚴重過載時,熔斷器中的熔斷體將自動熔斷,起到保護作用,常見的就是保險絲。
              In fact, small contactor is a kind of short-circuit protector, which is widely used in power distribution system and control system, mainly for short-circuit protection or serious overload protection. When working, the fuse is connected in series in the protected circuit. When the circuit short circuit or serious overload, the fuse link in the fuse will automatically fuse, play a protective role, the common is the fuse.
              另外還有斷路器,俗稱"空氣開關",也是一種短路保護器,當過流時,它會自動跳閘,起到保護作用;熔斷器、斷路器都是保護電器。但它們不是一樣.斷路器是總稱,它分為兩種——框架式斷路器和塑料外殼式斷路器。
              In addition, there is a circuit breaker, commonly known as "air switch", which is also a kind of short-circuit protector. When it is over-current, it will trip automatically and play a protective role; Fuses and circuit breakers are protective appliances. But they are not the same. Circuit breaker is a general term, it is divided into two kinds - frame circuit breaker and plastic case circuit breaker.
              框架式斷路器俗稱萬 能斷路器;塑料外殼式斷路器俗稱空氣開頭。他們具有短路和過載保護,可重復使用。壽命一般在幾千次到幾萬次。熔斷器是靠熔體熔化保護線路的一種電器,不可重復使用,保護以后需要更換熔體。
              Frame circuit breaker is commonly known as universal circuit breaker; Plastic case circuit breaker is commonly known as air circuit breaker. They have short circuit and overload protection and can be reused. The life span is from thousands to tens of thousands of times. Fuse is a kind of electrical equipment which depends on the melt to protect the circuit. It can not be reused and needs to be replaced after protection.
