Electrical Power Distribution Transformer Working Method

The operating voltage of Electrical power transformer should not be higher than 105% of the operating tap voltage, and should not exceed the maximum operating voltage of the system. For special use, it is allowed to operate under rated voltage of not more than 110%.
The top oil temperature of oil-immersed transformer shall not exceed the operating rules or the requirements of the manufacturer. For forced oil circulation water-cooled transformers, the top oil temperature should not often exceed 700℃.
The Electrical Power Transformer with strong oil circulation cooling should be able to control the cooler according to the temperature and/or load.

Electrical Power Transformers in operation should always monitor the instructions of instruments and keep abreast of the operation of transformers in time. If defects or abnormal phenomena are found, measures should be taken to eliminate them in time. If it could not be eliminated at that time, surveillance must be strengthened. Prevent accidents from expanding. The countermeasures are determined as soon as possible.

1. Water supply mode of Transformer cooling water system

When transformer is loaded, the cooling water is usually taken from the technical water supply pipe of the unit. When no-load is running, the cooling water is usually taken from the common water supply pipe of the power station, and is pressurized to supply water to the transformer through the no-load cooling water pump.

2. Drainage mode of Transformer cooling water system

Normally, the cooling water of transformer under no-load and load is discharged to the draft pipe of the unit through the main drainage pipe of the technical water supply system of the unit. Connecting valves are provided for drainage pipes of transformers. When the connecting valve is normally closed, the draft tube of the unit is required to be emptied while the transformer is still operating under narrow load. The connecting valve between the transformer and the adjacent transformer can be opened, and the no-load cooling water can be discharged to the draft pipe of other units.

CNC MACHINE BE CLASSIFIED BY SERVO CONTROL MODE

Servo control mode to classify CNC machine tool. (1) open loop control CNC machine tool The feed servo drive of this kind of machine tool is open-loop, that is, there is no detection feedback device. Generally, its driving motor is a stepping motor. The main feature of stepping motor is that every time the control circuit changes the command pulse signal, the motor will rotate a step angle, and the motor itself has self-locking ability. The drive circuit is controlled by the pulse distributor, which controls the coordinate displacement by changing the number of pulses, the displacement speed by changing the frequency of pulses, and the direction of displacement by changing the distribution sequence of pulses. Therefore, this control mode is characterized by convenient control, simple structure and low price. The command signal flow from the CNC system is unidirectional, so there is no stability problem of the control system, but because the error of the mechanical transmission...

SELECTION PRINCIPLE OF CUTTING PARAMETERS FOR SCREW THREAD TURNING

Because the pitch (or lead) of the thread is specified by the drawing, the key to choose the cutting parameters when  turning  the screw thread is to determine the spindle speed n and the cutting depth AP. 1) SELECTION OF SPINDLE SPEED TO DO SCREW THREAD TURNING According to the mechanism that the spindle turns 1 and the cutter feeds 1 lead when turning the thread, the feed speed of the CNC lathe is determined by the selected spindle speed. The thread lead (which is the pitch when the thread is single head thread) instructed in the thread processing program section is equivalent to the feed speed VF VF = n f (1) expressed by the feed rate f (mm / R) From Formula 1, it can be seen that the feed speed VF is proportional to the feed amount F. if the spindle speed of the machine tool is selected too high, the converted feed speed will greatly exceed the rated feed speed of the machine tool. Therefore, when selecting the rotation speed of the main shaft for turning the threa...

SCREW THREAD MACHINING METHOD

In  Metal parts machining  works, screw thread (tapping) be required. The screw thread is mainly divided into: connecting thread and driving thread For  connecting thread , the main  machining  methods are: tapping, threading, turning, rolling, etc. For  transmission thread , the main  machining methods  are: rough and fine turning – grinding；whirlwind  milling  – rough and fine  turning , etc. CNC turned screw thread part The following describes the various screw machining methods: THREAD CUTTING Generally, it refers to the method of machining thread on workpiece with forming tool or grinding tool, mainly including  turning , milling, tapping, threading, grinding and whirlwind cutting, etc. THREAD MILLING On the thread milling machine, the disc milling cutter or comb milling cutter is used for milling. Disc  milling  cutter is mainly used for milling trapezoid external thread of screw rod, worm and o...
