ABB微型断路器的4个极数的工作原理

来源:http://www.jntongyu.com/ 日期:2021-12-02 发布人:tongjid

断口极数一般用英文" P"表示,英文" pole",选型表里的1 P、2 P、3 P、4 P代表所选断路器1、2、3、4极的断路器。
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.
在实践中,由于电源相序排序为 A、 B、 C、 N, ABC指三相电流的火线, N指三相四线的零线,1 P可接任意一相火线;
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断路器可接任意一相火线和一零线;3 P断路器接三相火线;
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
当设备负载的额定电压为220 V时,即可使用1 P或2 P的断路器,如果是380 V,则需要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.
对于加载设备无需零时,仅选择3 P即可,如电机、风机、水泵等仅用3 P断路器;如380 V开水器、热水器等设备,则需4 P,并带有漏电保护功能的ABB微型断路器,这是为了防止漏电事故,保障人身安全是必须用的。
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.
熟知微断路器的朋友都知道,一般1 P的断路器宽度都是18 mm,2 P为36 mm,以此类推。模的数量表示小型断路器的宽度,1 P (单极)的断路器有两个模数,通常称一位。
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
因为模数的宽度是半位(9 mm),1 P断路器的宽度为18 mm。2 P (双极性)、3 P (三极)、4 P (四极)的断路器等等等等,如3 P (三极)宽为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微型断路器的宽度不一定与极数成比例,如施耐德的 DPNa系列,虽然是双极,却只占一个位(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,单相漏电断路器有很多种宽度,如通宇机电 VigiDPN系列,分为两位半宽(45 mm),新的 DPNa vigi+与 DPNN vigi+系列只有两个模块(18 mm,一个宽)。
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) .
