Boiler steam after Bao Biwen how? when shutdown to control steam drum wall temperature difference? From a run standpoint, what are the main measures to reduce coal consumption for power supply? Talk about how to control the water level? Generator after splitting, 6KV why to promptly exit the standby power switch? Why the current transformer secondary side in the operation are not allowed to open? Why synchronous generator excitation circuit of the degaussing switch can be changed into a lively breaker? Generator stepup process, why the rotor and stator currents to monitor? Why are rotor one point ground prone to 2nd after ground? Try 380V discussed following the grounding of auxiliary power system, wiring for threephase fivelimb terminal of PT secondary voltage change? Generator inplete phase operation principle is what? Yn,d11 (Y0/11) connection of generatortransformer systems, generator openphase running any help? Why to install 100% stator grounding protection for large generator? Why does not allow running secondary short circuit? Generator excitation, excited, what is the of the overexcitation limit? Generator loss of excitation in the running, what is the impact on the system and the generator itself? Anticuozhong on the prevention of excitation system of generator caused by fault what damage? try discussing what are the measures of improving power system dynamic stability? What is a switching operation of the electrical equipment? main content switching operation of power plants and power systems are there? Try discussing malignant electric misoperation, which misuse personal, most of the equipment? Switch service power fast cutting device in several ways? in the alternate to the State, the standby power switch refused to deal with? Try discussing switching operations should focus on preventing misoperation accident? New operation or after majorrepair of transformers why test? Try discussing steps measured with a Megger insulationresistance of electrical equipment? Lu method is used to find DC grounding considerationarewhat? when there are two point grounding with the polarity should be ... supercritical supplementary questions, blank mini disk can be divided into manual and two oil turbine。 oil turbine disc wheel car, the turning speed of the rotor can be controlled at around 80~120 RPM (high speed), and it is fulfilled by controlling access to the oilpressure turbine oil turning on/off and speed level. Mediumspeed Coal mill explosionproof steam from a wind room, _, _ separator casing into the ground to prevent the mill explosion in the process of starting and stopping. Mill load is to accept current signal to the coal control proportional pressure relief valve size, change of hydraulic accumulators and hydraulic cylinders, to achieve load changes. Sealed Air for coal pulverizer drive, Rod bearings, roller. Cold wind of a user with a sealed air blower air, sealed air, ground coal to a cold wind. Turbine sealing oil primary oil source is airside seal oil pump, the first alternate oil sources (mainly alternative oil source) is the main oil pump of turbine. When the primary oil source failure, the first spare source automatic put into operation. Second alternate oil sources primary alternate supply AC electric sealing oil pump on the fuel tank, when the turbine speed is less than 2/3 rated speed or first alternate source failure occurs, the second spare source automatic switch. Third alternative oil source is provided by DC sealing oil pump. Main fuel tank exhaust throttle should be located 2 steel closing door operation handwheel locking is not allowed and obvious warning signs should be hung. Steam engine room caught fire, when it threatened to tank or fuel system, shall immediately destroy the vacuum emergency stop, and turn on the tank accident put the throttle, speed and control on oil should be appropriate, to ensure that the rotors lubricants are not interrupted before static. Shaft seal overflow overflow to 8 the low pressure under normal conditions, when 8 the low pressure overflow when the outage to the condenser. Sliding pressure operation of deaerator may avoid deaerator steam source for throttling losses. Normal operation of steam turbine steam distribution mode for steam distribution nozzle. After the turbines stopped, if the rotor cannot rotate for a short time, rotor _ __ under bending, highest in __ ___ highs at this point rotor should be reset, close the hydrophobic __ __ cylinder, keeping __ up and down temperature difference between cylinder _ monitor rotor __ __ deflection, when after you verify that the rotor is, and then manually turning 180 186。. When turning the motor over current or rotor disc doesn39。t move, do not forcibly barring ___ __, but can not turn __ forced _ or turning the crane broke. Stop turning _8__ hours later, to stop the lube oil system. Condensate pumps due to transportation of saturated water, the pump is most prone to cavitation __ ___, therefore is posed of __ inducer __, and at the time of installation ensure the pump inlet has some highly ____ __ intrusion, and design _ export recycled __ tubes, also in order to solve this problem. When the condenser when the water level is too low _ setting up __ pumps are turned on, into the air to prevent the pump design __ ___ seal water, prevent the pump output is not normal. ... Threaded tube within a water wall, deterioration of heat transfer does not occur. X turbine cold starts, heat transfer of steam to the cylinder wall is based on condensation heat transfer and convective heat transfer in two ways at the same time. (X) the furnace higher excess air coefficient, smaller chemical heat loss due to inplete bustion. (√) Boiler of soda expansion is inevitable. √ Startup incorporations, boilerDC operation, adjustment of main st
