              ABB微型斷路器的4個極數的工作原理

              來源:http://www.cekidots.com/ 日期:2021-12-02 發布人:tongjid

              斷口極數一般用英文" P"表示,英文" pole",選型表里的1 P、2 P、3 P、4 P代表所選斷路器1、2、3、4極的斷路器。
              The number of broken pole is usually expressed in English “P”, English “Pole”. The 1P, 2P, 3P, 4P in the selection table represent the circuit breaker with 1,2,3 and 4 Poles.The number of broken pole is usually expressed in English “P”, English “Pole”. The 1P, 2P, 3P, 4P in the selection table represent the circuit breaker with 1,2,3 and 4 Poles.
              在實踐中,由于電源相序排序為 A、 B、 C、 N, ABC指三相電流的火線, N指三相四線的零線,1 P可接任意一相火線;
              In practice, because the sequence of power supply phase is A, B, C, N, ABC refers to three-phase current wire, n refers to three-phase four-wire zero line, 1P can be connected to any one-phase wire;
              2 P斷路器可接任意一相火線和一零線;3 P斷路器接三相火線;
              The 2P circuit breaker can connect any one phase fire line and one zero line, and the 3P circuit breaker can connect three phase fire lineThe 2P circuit breaker can connect any one phase fire line and one zero line, and the 3P circuit breaker can connect three phase fire line
              當設備負載的額定電壓為220 V時,即可使用1 P或2 P的斷路器,如果是380 V,則需要3 P或4 P。
              A 1P or 2P circuit breaker can be used when the rated voltage of the equipment load is 220V, or 3P or 4P if it is 380V.
              對于加載設備無需零時,僅選擇3 P即可,如電機、風機、水泵等僅用3 P斷路器;如380 V開水器、熱水器等設備,則需4 P,并帶有漏電保護功能的ABB微型斷路器,這是為了防止漏電事故,保障人身安全是必須用的。
              For loading equipment without zero, only choose 3P, such as motor, Fan, water pump only 3P circuit breaker, such as 380v water heater, water heater and other equipment, then need 4P, and with leakage protection function of ABB Miniature Circuit Breaker, this is in order to prevent leakage accident, to ensure personal safety is necessary.
              熟知微斷路器的朋友都知道,一般1 P的斷路器寬度都是18 mm,2 P為36 mm,以此類推。模的數量表示小型斷路器的寬度,1 P (單極)的斷路器有兩個模數,通常稱一位。
              Familiar with the micro-circuit breaker friends know that the General 1P circuit breaker width is 18 mm, 2p for 36 mm, and so on. The number of modules represents the width of the miniature circuit breaker. A 1p (unipolar) circuit breaker has two modules, usually one bit. Oh, Shit
              因為模數的寬度是半位(9 mm),1 P斷路器的寬度為18 mm。2 P (雙極性)、3 P (三極)、4 P (四極)的斷路器等等等等,如3 P (三極)寬為54 mm (六模)。
              Since the width of the modulus is half a bit (9mm) , the width of the 1P circuit breaker is 18mm. 2P (bipolar) , 3P (three-pole) , 4P (four-pole) circuit breaker and so on, such as 3P (three-pole) width of 54mm (six-mode) .
              有些ABB微型斷路器的寬度不一定與極數成比例,如施耐德的 DPNa系列,雖然是雙極,卻只占一個位(18 mm)。
              Some ABB miniature circuit breakers are not necessarily proportional in width to the number of Poles, such as Schneider’s DPNA series, which, although bipolar, occupy only one position (18 mm) .
              另外,單相漏電斷路器有很多種寬度,如通宇機電 VigiDPN系列,分為兩位半寬(45 mm),新的 DPNa vigi+與 DPNN vigi+系列只有兩個模塊(18 mm,一個寬)。
              In addition, the single-phase residual-current device comes in a variety of widths, such as the tongyu electromechanical vigidppn series, which is divided into two half-digit widths (45 mm) , and the new DPNA Vigi + and DPNN Vigi + series, which have only two modules (18 mm, one width) .
