GalloDry type transformer 2500kVAPublish Operation Guide

The heat discharge pipe of heat pipe radiator is generally made of slotted seamless steel pipe after flattening by stamping die. When the heat discharge pipe is bent and welded by electric welding, oil leakage is often caused. This is due to the supporting force on the surface of the pipe and the working pressure on the inner cavity when stamping the heat discharge pipe.

In order to better carry out the experiment of power transformer oil, it is necessary to sample the power transformer oil. The sampling work should be carried out on a dry sunny day. The commonly used containers and sampling methods during sampling do immediate harm to whether the specific quality of the oil can be truly reflected. The oil sample for AC voltage withstand test shall not be less than 0.5kg, and the oil sample for simplified experiment shall not be less than 1kg.

Gallo.Automatic system of centrifugal fan: measure the temperature data signal according to the PT100 thermistor temperature measuring resistor of the embedded parts at the hot part of the bottom pressure winding. The transformer load expands and the operating temperature increases. When the winding temperature reaches 110 ℃, the system software automatically starts the centrifugal fan for refrigeration; When the winding temperature is as low as 90 ℃, the system software will automatically terminate the centrifugal fan.

What is the important role of power transformer

.A specific part of dry-type transformer is the hanging core of dry-type transformer. The hanging core of dry-type transformer is a vital component. How to carry out the hanging core?

Some are tied with plastic tape, and some immediately press the two edges together because the socket can not be pressed firmly during installation, and there is still oil leakage without sealing effect.

There are also many problems to pay attention to in the preventive measures and process of dry-type transformer damping. What are the key effects and functions of dry-type transformer damping and the corresponding preventive measures? Let's master and consult in detail with the small editor of the dry-type transformer manufacturer.

Dry type transformer

The secondary inductive equipment of the distribution station (such as transformer, voltage transformer, automobile relay, etc.) operates normally. According to the AC current, the winding transformer core will send out a symmetrical rhythm and a certain tone & ldquo; Buzz, buzz & rdquo; Sound. The operation staff of the transformer manufacturer should understand and grasp the characteristics of the noise. When the equipment has common faults, there will be noise and even & ldquo; Crackle & rdquo; The charging and discharging sound can distinguish the generation and characteristics of common equipment faults according to the music law and sound transformation when everything is normal and abnormal.

Process inspection.Different diversion methods, dry-type transformers mostly use silica gel waterproof casing, while oil transformers mostly use porcelain waterproof casing;

Manufacturing process and steps of dry-type transformer

The technical specification of power consumption requires that the resistance of maintenance grounding wire shall be ≤ 4Ω, The resistor is generally more than 2000 & omega;, According to Ohm's law, when the insulating layer is damaged, the current is only 1 / 500 of the total current flow,GalloHow much is a 35kV Power Transformer,GalloDry type transformer, so as to play a guarantee effect. The higher the voltage, the smaller the resistance, in other words, bind the laminated glass stopper firmly with clean paper or cloth to prevent dirt and water from contaminating the bottle stopper.

Create brilliance.Before no-load impulse closing, the transformer shall be placed for 24h,GalloDry type transformer sample, and the rising seat and waterproof sleeve installed with vent plug shall be deflated on time.

How to select dry-type transformer

When the new oil filled by the power transformer and the oil sample that has just been considered are used, the oil sample can be used only after sufficient standing.

Gallo.Different diversion methods, dry-type transformers mostly use silica gel waterproof casing, while oil transformers mostly use porcelain waterproof casing;

In fact ground wire is not only a kind of grounding protection. The following describes in detail that ground wire is the general name of grounding system. Ground wire is divided into protective grounding and safety factor grounding device. Among them, safety factor grounding device can be divided into grounding protection, anti electric shock grounding device and anti electromagnetic wave radiation grounding device. Protective grounding is to use it for loop to make the facilities achieve the grounding wire specified by the function.

The clock expression is used to indicate the phase difference correlation of the working voltage of the secondary side line. The phasor of the working voltage of the primary side line is used as the minute hand, the fixed finger is at 12 o'clock, and the phasor of the phase voltage of the secondary side is used as the second hand.
