In specific daily life, oil immersed transformers are released outward in the form of waves. This kind of wave is like a tide. It is also a kind of kinetic energy. In fact, the greater the output power is. On the contrary, it is very small.

Before no-load impact closing, the pose period of overcurrent protection shall be set to zero, and the data signal circuit of steam vehicle relay shall be temporarily connected to the pull-in circuit.

Colin.Dry type transformer is a common electrical equipment, which can be used to convert the alternating voltage of one standard value into another standard value of the same frequency. The step-up dry-type transformer is used to convert the low-grade alternating voltage into another high-grade alternating voltage of the same frequency. It is widely used in high-frequency industries, such as variable frequency power supply.

When the full load test is carried out and everything is normal the load can be connected.

.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.

How to make up oil for oil immersed transformer?

The project cost is different. Compared with the purchase price of capacity transformer,ColinTypes of dry-type transformers, the purchase price of dry-type transformer is much higher than that of oil immersed transformer.

Welcome calls .The project cost is different. Compared with the purchase price of capacity transformer,Colin1000 dry type transformer manufacturer, the purchase price of dry-type transformer is much higher than that of oil immersed transformer.

When oil samples are used, the safety and fire safety technical specifications on the spot shall be strictly implemented.

The no-load impulse closing working voltage shall not exceed 5% of the working voltage marked on the gear of the transformer, the closing frequency shall be 5 times, the delay time after power receiving shall not be less than 10min, and the time interval of each closing shall not be less than 5min.

The power transformer belongs to relatively durable electrical equipment, and we can't neglect it in daily application. The common problems of power transformer conductor, power transformer winding and power transformer tapping power switch are analyzed below:

Discount.Falling foreign matters and piercing

The grounding resistance of, high voltage and bottom voltage shall not be less than 70% (10m & omega;) of the original value. The difference between the three-phase mean value of winding resistance measurement at the same temperature shall not exceed 2%, which shall not exceed 2% compared with the last accurate measurement result.

If the power transformer stops running for more than 72h (if the allowable time should be reduced when the ambient humidity is & amp; gt; 95%) it should be insulated before putting into use, and accurately measured with a 2500V grounding megger. The insulation resistance from the primary side to the secondary side and the ground should be ^ 300mfl, the insulation resistance from the secondary side to the ground should be ^ 100mh, and the insulation resistance from the iron core to the ground should be & amp; gt; 5mfl (note that the grounding device piece should be removed).

Colin.Causes of fire in power transformer

(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.

In the case of dry-type transformer operation, there is more noise, and some even cause noise, which seriously endangers everyone's no problem rest time and work. At this time, the dry-type transformer needs sound insulation treatment. There are many processes and key methods to deal with the noise of the common dry-type transformer. How should the noise of the dry-type transformer be solved? Or with the dry-type transformer manufacturer's network editor to simply understand it.
