                塑殼斷路器怎樣避免和接觸器發生線頭故障?這個問題值得大家來了解一番,下面來講講吧。
                How can molded case circuit breaker avoid wire head failure with contactor? This problem is worth understanding, let's talk about it.
                塑殼斷路器是能夠在電流超過跳脫設定后自動切斷電流的一種電氣設備。塑殼指的是使用塑料絕緣體來作為設備的外殼,來隔離導體之間以及接地金屬的部分。塑殼斷路器會含有熱磁跳脫單元,大型號的斷路器會配備固態跳脫傳感器。常用的斷路器額定電流有以下幾種:60、75、80/100/126/160/200A等等。
                Molded case circuit breaker is a kind of electrical equipment which can cut off the current automatically when the current exceeds tripping setting. Molded case refers to the use of plastic insulation as the outer shell of the device to separate conductors from each other and to ground metal parts. Molded circuit breakers may contain thermal-magnetic trip units, and larger ones may be equipped with solid state trip sensors. The common rated current of circuit breakers are as follows :60, 75, 80/100/126/160/200A, etc.
                在使用斷路器時,經常會遇到接觸器和斷路器線接好了卻不通電,在沒有測試的情況下拿去用,就會導致電路出現故障。很多人都懷疑這樣的原因是產品出了問題,其實是因為我們在接線的方式上出了問題,導致產品缺相或產生了相間短路的情況。下面跟大家介紹一下正確的接線方式。
                In the use of circuit breakers, often encounter contactor and circuit breaker wire is connected but not energized, in the absence of testing to use, will lead to circuit failure. Many people suspect that the reason is that there is something wrong with the product. In fact, it is because there is something wrong with the way of wiring, which leads to phase deficiency or short circuit between phases. Here is to introduce the correct way of wiring.
                引線。ABB塑殼斷路器代理認為要避免這樣的情況發生,首先,我們在接線前要選擇合適的引線,最好使用單股銅線,如果沒有,使用多股軟銅線,用錫將線頭焊接在一起,形成單股線。這樣做的目的就是防止多股銅線漏出產生短路狀況。
                Lead. ABB plastic case circuit breaker agent that to avoid such a situation, first of all, we should choose the right lead before wiring, the best use of a single copper wire, if not, the use of multiple soft copper wire, tin will be welded together to form a single wire. The purpose of this is to prevent the leakage of multiple strands of copper wire short circuit.
                接線方式。接線方式都采用線框方式接線,這樣做的好處是先不會像用1字型接線方式那樣會產生內部觸頭發生側滑,如果直接壓在接線框的旁邊,在擰緊螺絲的時候就容易造成靜觸點位移,導致斷路器接觸不良。
                Connection mode. Wiring mode are wire frame wiring, the advantage of doing so is not like using 1 type wiring mode will produce internal contact side slip, if the direct pressure next to the wiring frame, when tightening the screw is easy to cause static contact displacement, resulting in poor contact of the circuit breaker.
                螺絲選擇。接觸器采用螺絲帽壓片壓線,做成這樣的原因是當螺絲往下擰的時候壓片就會向下壓緊引線,也會讓產品在接線的時候有一個平衡點,接線也不會出現壓不緊的情況,降低了故障率。
                Screw selection. The contactor uses screw cap pressing plate to press the line. The reason for this is that when the screw is twisted down, the pressing plate will press the lead downward. It will also make the product have a balance point when wiring, and the wiring will not be pressed tight, reducing the failure rate.
