The double power interlock circuit can improve the operation safety of the main steam pressure regulating system in the retrofit of the boiler in power plant. The regulator receives the signals of main steam pressure, drum pressure and governing stage pressure. After internal calculation, IT SENDS OUT 4 ~ 20 MA signals to the general operator, which is responsible for the task of automatic and manual switching and synchronous direct operation. When the system is switched to automatic state, the total operator Sends 1 ~ 5V signal to the layer operator, and then the layer operator sends 1 ~ 5V signal to each single operator on the same layer, and then the single operator sends 4 ~ 20mA signal to the control converter, change the output frequency, control motor speed, to control the amount of powder. System in the manual state, direct operation of the button single operator, you can also control the amount of powder. The reliability of three-phase power supply plays an important role in the main steam pressure regulation system. Therefore, the regulating system uses a double power interlock circuit. The working principle is that after the knife switch is closed, the main power switch and the standby power switch are closed in turn, so that the main power supply is supplied by 6 inverters. When the main power supply failure, the main power supply side coil power loss, the standby power supply to 6 frequency converters to complete the automatic switching function. The actual power interlock circuit is powered by two groups of main and standby power sources, each group is powered by six inverters. To ensure the safe and reliable operation of the boiler unit, the interlock signals of full stop and stop of the forced draft fan and boiler are introduced in the circuit. INVERTER is not in any case can be normal use, so it is necessary for users to have more knowledge of the load, environmental requirements and inverter. 1. Load type and frequency converter selection: Motor driven by the load is not the same, the frequency converter requirements are not the same
六月的夜晚，星星闪烁着亮晶晶的光芒，一点，两点，三点……璀璀璨璨，闪烁不定，就像一双双淘气、幼稚，然而又充满神秘、智慧的眼睛。它们仿佛看到了我们，便和我们玩儿起“藏猫猫”的游戏来。它们那灵巧的身躯，东躲西藏，时隐时现，弄得我们眼花缭乱。忽然，一颗流星飞来，吸引着我们的目光，一眨眼的工夫，它又从我们的目光底下隐遁了。我高仰起头，睁大眼睛，从西到东，仔仔细细地察看了一遍，却连个影子也找不着。
