Bandundu400 KVTherefore, in the installation process of substation equipment the lightning rod should be set according to the specific situation to prevent damage to the relay protection dry-type transformer caused by lightning. In addition, in the installation and use process of lightning rod, select reasonable types of lightning rod according to the operation situation to determine that they are in the same situation. In addition, during the installation of lightning rod,BandungPower transformer oil immersed, please connect all routes as far as possible to prevent other faults.
Avoid inadvertent damage of insulation during maintenance: when repairing the hanging core of power transformer, special attention shall be paid to the maintenance of solenoid coil or insulating waterproof sleeve. If there is scratch damage, it shall be handled properly.
Bandung.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.

Oil immersed transformer operation
The hanging core of dry-type transformer is a vital part
(III) dry type transformers of 315KVA and below can be installed on poles. The distance between its bottom end and the road surface shall not be less than 5m; The distance between the electrified part and the road surface shall not be less than 5m.
It can be seen from the above that from the perspective of power saving, in some cases, transformers & ldquo; A small horse pulls a small car & rdquo; Can't compare with & ldquo; Middle car & rdquo;, Even less than & ldquo; Great Lars, little dragons & rdquo;, Therefore, the loss of transformer full load and load must be considered in the calculation, that is, the operating load and rated capacity of the transformer 1. Now it is illustrated by examples that both sides of the acadc al electron touch toe ground type seek the derivative of P, and then reduce the active power loss of the large capacity transformer from the active power loss of the small capacity transformer: that is, and the rate is large when the specific copper loss is equivalent to iron loss.
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.

The noise of dry-type transformer belongs to low-frequency noise. In a small area, most of it is scattered according to the building structure. This kind of low-frequency noise is scattered to the household house according to the house building,BandungDifference between oil immersed transformer and dry-type transformer, and then causes gas vibration noise, which is then scattered to the ears of consumers. Although the amount of noise is not very large, the dispersion spacing and adverse effects are very large.
Insulation and heat removal are different. Dry type transformers are generally insulated with epoxy resin, cooled by natural air and large capacity by centrifugal fan. Oil immersed transformers are insulated by insulating oil, insulated by insulating oil in the circulating system inside the transformer, and heat is discharged on the radiator (radiator) of the circulating system inside the transformer.
Wiring mode of dry-type transformer:
Application process.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.

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,BandungOil immersed transformer capacity, dry-type transformer should operate under rated capacity, while oil transformer has better load working capacity.

Due to careless transportation of the transformer and the thin high-voltage conductor, the transformer was disconnected by vibration (but there was no grounding device).
