为确保电阻制动控制箱装车之后的正常运行,在装车前需要进行性能检查,该项检查可以借助电阻制动控制箱测试台来进行,也可用外加电压的办法进行。下面将分别予以介绍。一、外观检查检查控制箱在运输过程中是否有严重摔、撞、损坏之处,开关、按钮动作是否正常,插座、插针有否弯曲变形。如有必要还可以打开机箱观察内部有无明显损坏之处。 In order to ensure the normal operation of the resistance brake control box after loading, a performance check is required before loading. This check can be performed by means of a resistance brake control box test stand or by applying an external voltage. The following will be introduced separately. First, the appearance of the inspection Check the control box in the transport process whether there is a serious fall, collision, damage, switch, button action is normal, socket, pin bending deformation. If necessary, you can also open the case to observe the internal obvious damage.
