Transformer body structure
This paper mainly introduces the structure of transformer body from three aspects: core, winding and lead.
I.Transformer core structure
01 The role of silicon steel(Iron) core
Transformers are based on the principle of electromagnetic induction, the magnetic circuit is the medium of electrical energy conversion. Iron core is the main magnetic circuit of the transformer, the main role is magnetic. It converts the electrical energy of the primary circuit into magnetic energy, and from magnetic energy into electrical energy of the secondary circuit.
At the same time, the iron core is the mechanical skeleton of the transformer, and the clamping device of the iron core not only makes the magnetic conductor into a mechanical complete structure, but also has an insulated coil on it, supporting the lead, and almost all the components inside the transformer. The weight of the iron core is the largest in the transformer components, accounting for about 60% of the total weight in the dry transformer, and about 40% in the oil-immersed transformer.

How to optimize transformer design for PoE Power Supply
Power over Ethernet - The Power supply technology refers to a way for PSE (Power souring Equipment) to transmit Power to PD (Power Device) through network cables. Typical applications, for example, take PSE switch as the core, connect numerous PD devices such as Access Point, IP Phone and IP Camera through network cables, and PSE completes signal and power transmission to PD.

Box transformer is the integration of high and low voltage primary equipment, transformer, secondary equipment in the factory in a double layer, sealed, anticorrosive, movable outdoor box.
Box type substation, also known as preinstalled substation or preinstalled substation. Is a kind of high voltage switch equipment, distribution transformers and low voltage power distribution equipment, according to the wiring scheme must be arranged in one of the factory indoor, outdoor compact type distribution equipment, the step-down transformer, low voltage power distribution, and other functions organically combined together, installed in a moisture, rust, dust, rat, fire prevention, guard against theft, heat insulation, fully enclosed, movable steel box, Especially suitable for urban network construction and transformation, it is a new substation after the rise of civil substation. Box-type substation is suitable for mines, factories, oil and gas fields and wind power stations. It replaces the original civil power distribution room and power distribution station and becomes a new complete set of transformer and distribution devices.

1.Why should the core of the transformer be grounded?
2.Why do transformers use silicon steel sheets as cores?
3.What is the scope of gas protection?
4.What are the differences between main transformer differential and gas protection?
5.How to deal with the fault of main transformer cooler?
What to know more, see below

transformer is static equipment running continuously, running more reliable, less chance of failure. But because the vast majority of transformers are installed outdoors, and are affected by the load during operation and the influence of short circuit fault of the power system, various faults and abnormal conditions are inevitable in the process of operation.

Good news! Our company will participate inBooth: B22, the 3rd Ghana electricity exhibition (6-8 September 2018)。Our company will introduce more new equipment during the exhibition.Thank you for your support and trust inCANWIN machinery. Thanks for your attention!

1. The machine tool in the long-term use of friction, wear, screw clearance with the increase, the machine tool screw reverse clearance.

2. The tool used for processing the workpiece is not the right type, easy to damage, the tool clamping is not correct or tight, etc..

3. Choose reasonable spindle speed, cutting speed and cutting amount according to the workpiece material.

4. It is related to the balance and stability of machine tool placement.

1.Employees accurately wear labor insurance products before work
2.Ensure the equipment safety protection equipment integrity, useful;
3.Be familiar with the risk factors of the post and corresponding prevention measures;
4.Strictly abide by the request of safety operation procedure in work;
5.Do not take risks, do not work fatigue, do not operate their own unfamiliar equipment.

The tool track editing system is composed of tool track transformation,
cutting line editing, graphic display of tool track, loading and output
of tool track, etc.

Definition of equipment maintenance.By wiping,
cleaning, lubrication, adjustment and other general methods of equipment
care, in order to maintain and protect the performance and technical
status of equipment, called equipment maintenance.

The main difference between CNC cutting machine and hand-held cutting
and copying cutting lies in its fast cutting speed and high cutting
accuracy.But many users in enough to buy CNC cutting machine, feel that
the processing efficiency has not been greatly improved.In the final
analysis, the main user of CNC cutting machine knowledge is not enough
to understand, can not use it.In view of these situations, we can adopt
the following methods to solve.

The word servo comes from the Greek word for slave."Servo motor" can be
understood as a motor that absolutely obeys the command of the control
signal.When the control signal is sent, the rotor immediately rolls.When
the control signal disappears, the rotor can stop running immediately.
