According to the condition of cracks, galvanized iron wire can be punched into the leakage or riveted with hammer. Then clean the leakage point with toluene and seal it with raw materials. Coated sand casting eyes can be sealed with raw materials immediately.

Noise solution of dry-type transformer

Batman.Two point grounding device of iron core caused by residual welding scar;

The power transformer is composed of two or more electromagnetic coils wound around the same transformer core. The winding resistance is connected according to the alternating electromagnetic field and works according to the basic principle of magnetic effect of current. The installation position of power transformer shall be considered to be conducive to operation, and a reliable area shall be selected at the same time. The rated capacity of the transformer must be effectively used when applying the transformer.

.Then clamp the branch pipe with your thumb, clearly put forward the glass test tube, rotate and release the oil in the tube to clean the sampling tube, carry out it twice, and then draw the oil sample.

The zero line is mainly used in the working circuit. The voltage caused by the zero line is equivalent to the line resistance multiplied by the current of the working circuit. Because of the distance, the voltage caused by the zero line can not be ignored. As a countermeasure to maintain life safety, it is more and more unreliable. Ground wire (PE): it is not used as a working circuit,BatmanElectrical equipment transformer, but only as a maintenance line. Use the affirmation of the earth & ldquo; 0” Voltage. When the machine and equipment casing is electrified, the current will be quickly grounded. Even if there is a lead for the PE line, it will be grounded from the surrounding grounding body.

Oil leakage of heat pipe radiator

It will also produce many faults, effectively deal with various faults of oil immersed transformer, make full use of the performance indicators and advantages of oil immersed transformer, and continuously improve the safety factor of oil immersed transformer. Ignition is a common fault of oil immersed transformer. The key fault of oil immersed transformer is short-circuit fault, and short-circuit fault is more general.

It is understood that in China transformers have experienced the whole process of replacing many series products such as sss11. As early as the middle and late 1980s,BatmanPower transformer technology series, S7 Series lossless distribution transformers were selected in China to replace the high energy consumption transformers of jb1300-73 and jb500 - Specifications operating in the power network at that time. Since the 19th century, urban power grids have been transformed all over the country, and S9 series distribution transformers have been used to replace S7 Series. In recent years, and their full load loss is 50% - 80% less than that of S9 transformer.

What is the wavelength of oil immersed transformer?

demand.The power transformer is designed according to the temperature protection scheme. The embedded parts in the material layer of high (low) pressure electromagnetic coil poured with integral concrete are provided with longitudinal ventilation duct, which can be equipped with air-cooled machinery and equipment (cooling centrifugal fan). After selecting air-cooled machinery and equipment, the output capacity can be increased by 20%.

When checking the hook core, the insulation of the electromagnetic coil and the porcelain sleeve is usually accidentally damaged. After the shell of the pottery is broken, turn on the photo flash when it's light, and it's short when it's heavy. Therefore, please pay attention during maintenance. It is not necessary to destroy the insulation. After maintenance, experts can inspect special tools, parts, insulation, etc. and deliver them after they are determined to be complete and reliable.

For no-load impulse closing of transformer, pay attention to the following matters:

Fault judgment of power transformer

technological innovation.The bearing capacity of each load is different. Generally, dry-type transformer should operate under rated capacity, while oil transformer has better load working capacity.

The iron loss of transformer includes two levels. The first is the hysteresis loss introduced by the transformer manufacturer. When the AC circuit is based on the transformer, according to the magnetic induction line of the transformer ferrite core, its orientation and size change with the change which promotes the internal molecular structure of the ferrite core to interact with each other, releases energy, and then loses part of electromagnetic energy which is the hysteresis loss. The other is the vortex loss when the transformer is working.

When the manufacturer of the power transformer samples from the automobile oil tank, after opening the sealing cover, use the cleaned and dried rubber stopper to the oil. At the same time, clamp the branch pipe with your thumb, and loosen your thumb to make the oil enter the pipe,BatmanOil change steps of oil immersed transformer,

Batman.When sampling from a small and medium-sized power transformer without a discharge pipe (or oil sample suspension plate), it can be in a power transformer such as a glass test tube when it is not in operation to extract the oil sample at the bottom, or it can be replaced by changing the oil.

The cross-sectional wiring of transformer input and output power plugs shall comply with the provisions of their current size; It should be equipped according to the current intensity of 2-5A / Min2.

Outdoor sampling shall be carried out in sunny days or dry weather with low environmental humidity. During sampling, it is necessary to resolutely prevent the invasion of dirt such as rain, snow, wind and sand.
