Oil immersed power transformer Cooling methods and Standard

How many cooling methods do oil immersed power transformer have? And what is the Oil immersed power transformer Cooling methods Implementation Standard?

Cooling mode of Oil immersed Power Transformer

In the operation of oil-immersed power transformer, the heat of winding and iron core is transferred to oil first, and then to cooling medium through oil. The cooling methods of oil-immersed power transformer can be divided into the following types according to the capacity:
1. Natural Oil Circulation Natural Cooling (Oil-immersed Self-Cooling)
2. Natural Oil Circulation Air Cooling (Oil-immersed Air Cooling)
This cooling method adopts corrugated fin cooler wall or radiators.

3. Forced oil circulating water cooling
4. Forced Oil Circulation Air Cooling

Normal operating conditions of distribution transformers:

1. Household or outdoor not exceeding 1000 m above sea level
2. Maximum ambient temperature + 40 Maximum daily average temperature + 30.
3. Maximum annual average temperature + 20 C minimum temperature – 25 C
4. Transformers operating under special conditions can be provided according to user’s requirements.

Implementation Standard for Oil immersed Power Transformer

A, GB1094.1-2-1996, GB1094.3,.5-2003 power transformers;
B, GB/T6451-2008 three-phase oil-immersed power transformer technical parameters and requirements.

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...

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...

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...
