| 机械调试 Mechanical debugging 该方式主要是通过对手操部件和抽屉对配电柜进行调试。目的：检验每个机构是否灵活操作，质量可靠，抽屉在检验时要特别注意，连接与断开位置定位是否可靠尤为重要。上述这些都直接影响到低压配电柜能否正常使用。 The main method is to debug the distribution cabinet through the opponent's operator and drawer. Objective: to test whether each institution flexible operation, reliable quality, drawer should pay special attention to when inspection, reliable connect and disconnect position location is particularly important. All of these directly affect the normal use of low voltage distribution cabinets. 蜗牛分割线 The snail line 电气调试 Electrical commissioning 电气调试又分为三大类： There are three main types of electrical debugging: 电气操作实验；连锁功能试验；绝缘测试。 Electrical operation; Chain function test; Insulation test. 电气操作实验 Electrical operation experiment 在安装和接线都正确的前提下，按电气原理图进行模拟动作试验，即通电试验。主要包括：断路器合、分闸是否正常；按钮操作及相关的指示灯是否正常；手动投切是否正常；这种试验，要一台一台进行，先进行柜子的调试，然后将抽屉逐一调试如果是抽屉柜，要一只抽屉、一只抽屉调试。 In the case of installation and connection, the simulation test is carried out according to the electric principle diagram. Main include: circuit breaker close, divide lock is normal; Button operation and related indicator lights are normal; Manual casting is not normal; This kind of test, should undertake a a, first for the debugging of the cabinet, then put the drawer by commissioning if it is a chest of drawers, a drawer, a drawer debugging. 联锁功能试验 Interlocking function test 通电检查操作机构与门的联锁，抽屉与门的联锁。在合闸（通电）情况下，门是打不开的。只有分闸以后，才可以开门。双电源间的机械或电气联锁在正常电源正常供电时备用电源的断路器不能合闸， 在主电源切断时，备用电源自动完成互投。 The interlock of the operating mechanism and door, the interlock of the drawer and the door. In the case of the closed circuit, the door cannot be opened. Only after the lock can be opened. Mechanical or electrical interlock between the double power supply when the power is in the normal power supply is normal standby power circuit breaker closing, in the main power supply cut off, standby power supply automatically for each other. 绝缘电阻测试 Insulation resistance test 为确保操作人员、柜体、柜内器件的安全，绝缘电阻测试是必不可少的。其主要测量的部位有：开关柜的主开关在断开位置时，同极的进线和出线之间；主开关闭合时不同极的带电部件之间；主电路和控制电路之间；各带电元件与柜体金属框架之间。测试时间要达到1分钟，测试电阻必须达到0.5MΩ。 Insulation resistance testing is necessary to ensure the safety of operating personnel, cabinets and devices. Its main measurement is: the main switch of the switch cabinet is between the pole and the line. When the main switch is closed, different poles of charged parts; Between the main circuit and the control circuit; Between the charged components and the metal frame of the cabinet. Test time to 1 minute, must achieve 0.5 M Ω resistance. |
