What do you know about the Dry Type transformer?

You must be unfamiliar with the term dry-type transformer size, don’t you know what it means? Now we come to understand.

What is the structural performance of dry type transformers?

How is Dry Type transformer used?

What is the structural performance of dry type transformers?

solid insulation encapsulated winding,

No wrapping

winding: Of the two windings the higher voltage is the high voltage winding and the lower the low voltage winding.

From the perspective of the relative position of the high and low voltage developments, the high voltage can be divided into concentric and overlapping types.

The concentric winding is easy and comfortable to manufacture, and this construction is taken over.

Overlapping type, mainly used for special transformers.

How is Dry Type transformer used?

1. Use a mega-meter to test the insulation resistance between the terminals "input" and "output" of the dry type transformer. When measuring with a 1000-V-megger, the resistance is greater than 2 M Ohm.

2. The cross-section of the input and output power cables of the dry type transformer should meet the requirements of the current value; it is appropriate to configure it according to the current density of 2-2,5 A/min2.

3. The three-phase input and output power cables should be connected to Phase A, Phase B or Phase C respectively according to the colour of the assembly line of the transformer terminal block yellow, green and red. The neutral wire should be connected to the neutral wire of the transformer, the ground line and the transformer. The ground and neutral conductors we normally talk about are drawn from the core of the transformer. (If the transformer has a cabinet, it should be connected to the corresponding grounding marking of the cabinet).

Check the input and output lines to make sure they are correct.

4. First switch on without a load, observe and test whether the input and output voltage meets the requirements. At the same time, observe the machine

Regardless of whether there are unusual sounds, sparks, strange smells, etc., inside, please disconnect the input voltage immediately.

5. After the emptying test is complete and normal, the load can be connected.

What is the future of the dry type transformer?

1. Multifunctional combination: From single transformer to multi-functional combined transformer with air cooling, protective housing, temperature computer interface, zero system transformer, power measurement, accompanying current rail and lateral outlet. ockentransformattor with superior performance, low noise level and energy saving.

2. Large capacity: From dry type transformersbased on 50'653742500kVA distribution transformers up to 10000'6537420000kVA/35kV power transformers, as the city's electricity load continues to rise, the regional branches of the urban network penetrate deeper and deeper into the central area of the city, residential areas, large factories and rgwerke and other load centres, 35-kV large-scale power supply transformers for district centres will be widespread.
