              從哪幾個方面來判斷接觸器的好壞?

              來源:http://www.cekidots.com/ 日期:2021-10-12 發布人:tongjid

              可以從以下幾個方面來測試下接觸器的好壞,一是看接觸器的線圈,二是看接觸器的觸頭,三是看電磁機構吸力是否充足。

              The quality of the contactor can be tested from the following aspects: first, the coil of the contactor, second, the contact of the contactor, and third, whether the suction of the electromagnetic mechanism is sufficient.
              1、接觸器的線圈
              1. Coil of contactor
              查看接觸器線圈的額定電壓,連接到相匹配的電源上,打開開關,查看接觸器是否吸合。如果不吸合,說明接觸器線圈存在故障問題。
              Check the rated voltage of the contactor coil, connect it to the matching power supply, turn on the switch and check whether the contactor is closed. If not, the contactor coil is faulty.
              或使用萬用表測量接觸器線圈的電壓,對于沒有相關經驗的來說,可以用一個新的同樣功率接觸器的參數來作為參考。
              Or use a multimeter to measure the voltage of the contactor coil. For those without relevant experience, the parameters of a new contactor with the same power can be used as a reference.
              從哪幾個方面來判斷接觸器的好壞
              From which aspects can we judge the quality of the contactor
              2、接觸器的觸頭
              2. Contact of contactor
              如果接觸器可以吸合,三相電源也正常,輸出端卻出現缺相的情況,可以通過測量三相任意兩相的電壓來判斷。
              If the contactor can be pulled in and the three-phase power supply is normal, but there is a lack of phase at the output end, it can be judged by measuring the voltage of any two phases of three phases.
              這時需要檢查接觸器的主觸頭,查看有沒有磨損燒毀的現象,如有則及時更換。
              At this time, it is necessary to check the main contact of the contactor to see if it is worn or burned. If so, replace it in time.
              3、電磁機構吸力不足
              3. Insufficient suction of electromagnetic mechanism
              一般表現為可以吸合,但主觸頭下端有缺相,施加外力外力后,缺相消失,這種也要及時更換。
              Generally, it can be pulled in, but there is a lack of phase at the lower end of the main contact. After external force is applied, the lack of phase disappears, which should also be replaced in time.
              電動機缺相的表現:振動加大、有異常聲響、溫度升高、轉速下降、電流加大、啟動時有強烈的嗡嗡聲無法啟動。
              Performance of motor phase loss: increased vibration, abnormal sound, increased temperature, decreased speed, increased current, strong buzzing during startup, unable to start.
              當出現上述現象時,應重 點檢查電源和接觸器有沒有缺相現象,需要及時更換,以避免產生更大的損失。
              When the above phenomena occur, focus on checking whether the power supply and contactor are out of phase and need to be replaced in time to avoid greater loss.
