Q & a ` furEconomic operation of power transformerWhat details should be paid attention to during operation

The tap changer of power transformer shall also have strong insulation. 10kV off load tap changer is generally insulated from the ground by the produced insulating paper pipe factory.

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?

Q & a ` fur.The transformer manufacturer said that the temperature display equipment: the temperature change value is measured according to the PT100 temperature sensor embedded in the bottom voltage winding to immediately indicate the winding temperature of each phase (three-phase safety inspection and Zui large value indication, and the historical time Zui high temperature can be recorded). The Zui high temperature can be input and output as 420mA analog quantity. If it is to be far away (the distance can reach 1200m, the electronic computer can be equipped with an electronic computer socket an intelligent transmitter, so as to further improve the stability of the temperature maintenance system software.

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.

.If the above provisions are not met, the problem of dryness shall be solved. Generally, it is OK to operate the centrifugal fan for a period of time. Check the cleanliness of the power transformer. If too much dust is found, it must be eliminated to ensure indoor ventilation and avoid insulation penetration. In particular, pay attention to cleaning the insulators of the power transformer and the top and bottom ends of winding resistance installation. Portable centrifugal fan or dry air compression or N2 shall be used to clean the dust in indoor space that is not easy to reach, such as ventilation duct, and there shall be no dirt.

Analysis of common faults of oil immersed transformer:

What is the wiring mode of dry-type transformer?

It includes the performance and main uses of insulating layer materials, various insulating layer parts, component manufacturing processes and quality standards; Performance and main uses of various wires, coil inductance process of various ways of electromagnetic coil, solution process and quality standard, overall suit process and quality standard of electromagnetic coil; Main performance parameters of ferrite core, cutting process of iron chip,Q & a ` furOil immersed transformer components, core stacking process and quality standard, production process and quality standard of electromagnetic shielding.

The top and middle of the transformer oil tank, the flange plate, barrel skin and the middle of the waterproof sleeve at the upper end of the automobile oil tank. The internal iron core and winding clamp are hot due to partial magnetic leakage, resulting in insulation damage.

Connection group structure of dry-type transformer

Executive standard.Different diversion methods,Q & a ` furTechnical parameters of scb12 dry type transformer, dry-type transformers mostly use silica gel waterproof casing, while oil transformers mostly use porcelain waterproof casing;

High voltage fuse of transformer breaks one phase;

The capacity and working voltage are different. The dry-type transformer is generally suitable for distribution equipment. The capacity is generally below 2000kVA and the working voltage is below 35KV, which also ensures the rated voltage of 110kV; Oil immersed transformers are generally suitable for distribution equipment.

The switching power supply lacks one phase of power;

demand.After the oil is drained all anchor bolts of the automobile oil tank at the upper end of the detachable oil cover shall be tied with the lifting jack, and the lifting point shall be on the common earrings or bolts. If necessary, the human resources traction belt shall be used as a guide.

How to select dry-type transformer

Plug in the power with full load first, observe and detect that the input and output voltage meets the regulations. At the same time, check whether the equipment has abnormal sound,Q & a ` furAlarm temperature of dry-type transformer, ignition, odor and other abnormal conditions. If there is any abnormality, please cut off the input switching power supply.

Q & a ` fur.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, wind and sand.

In specific daily life, we have a certain understanding of the optical wavelength of oil immersed transformer. What kind of function does it have for transformer?

The sampling container is a colorless glass bottle with a wide mouth ground glass plug with a volume of 0.5kg or 1kg. 2-3 bottles shall be collected at a time for analysis and experiment. Labels shall be attached during sampling. Pay attention to the name, source, sampling person, weather conditions and other materials of the oil sample.
