Difference between dry-type transformer and oil immersed transformer:

High voltage fuse of transformer breaks one phase;

Gilardiot.The proper selection of Anhui dry-type transformer has a key effect on improving the safety and smooth operation of power system software. In the above original text, we have already mastered the structure and characteristics of dry-type transformer. In this part, we will describe how to select dry-type transformer according to the load characteristics and application environment of dry-type transformer.

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).

.Oil leakage of cast iron parts

Use fiber materials to seal the bolts to achieve the goal of controlling leakage. The other is to screw out the bolt (nut), wipe the Fushi blue film remover on the surface,GilardiotInsulation heat resistance grade of oil immersed transformer, and then tighten it after wiping the raw materials on the surface. After drying, the treatment goal can be achieved.

What is the important role of power transformer

Avoid the load operation of power transformer: if the load operation is long-term, it will lead to the scalding of solenoid coil, slow aging of insulation, short circuit fault between boxes, two-color short circuit fault or short circuit to ground fault and dissolution of oil.

The transformer manufacturer shall not use hand touch method to detect energized high-voltage equipment, the temperature or temperature rise must be tested by hand. The secondary equipment can be inspected by hand touch method when it is hot and vibrated.

When we apply oil immersed transformer,GilardiotOil immersed high voltage test transformer, we all know that it works with the help of oil. What if the oil immersed transformer is on fire? What countermeasures should we do?

How much is it.The insulating layer in the middle of the silicon steel plate is aging the anchor bolt cover with the iron core is damaged, the iron core causes large vortex, resulting in heat, temperature rise and the aging of the insulating layer is accelerated. The core insulation compressive strength of power transformer must be measured on time and accurately. If it is found that the insulation compressive strength is less than the index value, the purchase price of dry-type transformer is much higher than that of oil immersed transformer.

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

Oil immersed transformer

ranking.The noise of dry-type transformer is mainly the vibration noise in operation. This vibration noise is caused by multiple positions, including the vibration of magnetic induction electromagnetic coil. All pay great attention to the solution of vibration when carrying out noise control.

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, and 31 transformers can be detected. The over temperature alarm and trip of the system software can also be signaled by the resistor data of Pt100 thermistor sensor, so as to further improve the stability of the temperature maintenance system software.

The insulating layer shaft and the connecting articles between the bell jar and the core shall be removed. If it is a hanging bell inspection, the oil shall be pumped into the bottom of the bell jar before the bell jar can be removed.
