              塑殼斷路器線圈燒毀的原因

              來源:http://www.cekidots.com/ 日期:2021-06-07 發布人:tongjid

              一、塑殼斷路器開路線圈燒毀

              1、 The open coil of MCCB is burnt out
              1、開式電磁鐵的機械故障。當線圈松動時,電磁鐵鐵芯在斷路器斷開時移動,鐵芯卡住,線圈燒毀。還可能由于鐵芯的主動行程較短,當開啟電路的電源接通時,鐵芯不會打開跳閘機構,使線圈長時間通電,造成燃燒。
              1. Mechanical failure of open electromagnet. When the coil is loose, the electromagnet iron core moves when the circuit breaker is disconnected, the iron core is stuck, and the coil is burned. It is also possible that due to the short active stroke of the iron core, when the power to open the circuit is turned on, the iron core will not open the tripping mechanism, and the coil will be electrified for a long time, causing combustion.
              2、死點調整不當,機構無法及時釋放,導致線圈過載,使分閘線圈燒毀。
              2. Improper adjustment of dead point makes the mechanism unable to release in time, resulting in overload of coil and burnout of opening coil.
              3、輔助開關開路狀態調整不當,檔輔助開關超出了分閘狀態的行程范圍時,會導致輔助開關無 法 正常切換分閘回路,導致分閘線圈燒毀。
              3. If the open circuit state of the auxiliary switch is not adjusted properly and the auxiliary switch is beyond the travel range of the opening state, the auxiliary switch will not be able to switch the opening circuit normally and the opening coil will be burned.

              4、輔助開關觸電使用不當。當斷路器的合閘時間很短時,遠遠小于斷路器的開啟時間,斷路器不及時,則斷路器處于關閉位置。開關控制電路的延遲觸點的延遲效應會消失,相反的,由于輔助開關的動、靜觸電絕緣間隙小,經常發生拉弧現象,燒壞輔助開關觸點,造成線圈燒壞。
              4. Improper use of auxiliary switch in case of electric shock. When the closing time of the circuit breaker is very short, far less than the opening time of the circuit breaker, and the circuit breaker is not in time, the circuit breaker is in the closed position. The delay effect of the delay contact of the switch control circuit will disappear. On the contrary, due to the small insulation gap between the dynamic and static electric shock of the auxiliary switch, the arcing phenomenon often occurs, which burns out the auxiliary switch contact and causes the coil to burn out.
              5、當裝置中的分流繼電器發生故障,或者分流器的輔助開關觸點有較大的以偶定,會導致分流器不能及時退出,分流器線圈會長時間通電,導致燒毀。
              5. When the shunt relay in the device fails, or the auxiliary switch contact of the shunt has large coupling, the shunt can not exit in time, and the shunt coil will be energized for a long time, resulting in burnout.
              6、當開關線圈的電路絕緣降低,或電路電阻過小時,會導致開關電路電壓衰減,導致電壓達不到線圈開關的電壓值,導致開關線圈充電時間過長,燒毀線圈。
              6. When the circuit insulation of the switch coil is reduced, or the circuit resistance is too small, the voltage of the switch circuit will be attenuated, resulting in the voltage not reaching the voltage value of the coil switch, resulting in the switch coil charging time is too long, and the coil will be burned.
              二、塑殼斷路器閉合線圈燒壞的原因
              2、 The reason of closing coil burn out of moulded case circuit breaker
              1、斷路器本體的內導電桿由于斷路器工作機構不匹配,傳動連桿的阻塞不好,由于保護鎖緊聯鎖機構操作不當,機構無法開啟斷路器,導致關閉線圈因合閘鐵芯過載而燒毀。
              1. Due to the mismatching of the working mechanism of the circuit breaker, the blocking of the transmission link is not good. Due to the improper operation of the protection locking interlock mechanism, the mechanism can not open the circuit breaker, resulting in the burnout of the closing coil due to the overload of the closing iron core.
              2、當保護控制裝置發出開啟指令時,裝置中的開關繼電器發生故障或者閘門控制回路的輔助開關的操作行程大,就無法及時撤回開啟指令,導致開關線圈被長時間充電并燒毀。
              2. When the protection and control device sends the opening command, the switch relay in the device fails or the auxiliary switch of the gate control circuit has a large operation stroke, so the opening command cannot be withdrawn in time, resulting in the switch coil being charged and burned for a long time.
              3、當斷路器閉合時,由于閉合電流較大,控制回路不能直接控制閉合線圈,只能通過閉合接觸器間接連接閉合線圈,當閉合接觸器失效時,不能及時斷開,導致閉合線圈開啟時間過長,燒毀線圈。
              3. When the circuit breaker is closed, due to the large closing current, the control circuit can not directly control the closing coil, and can only indirectly connect the closing coil through the closing contactor. When the closing contactor fails, it can not be disconnected in time, resulting in too long opening time of the closing coil and burning the coil.
