The clock expression is used to indicate the phase difference correlation of the working voltage of the secondary side line. The phasor of the working voltage of the primary side line is used as the minute hand, and the phasor of the phase voltage of the secondary side is used as the second hand.

.Then clamp the branch pipe with your thumb,BendibujoBox type transformer 400kV, clearly put forward the glass test tube rotate and release the oil in the tube to clean the sampling tube, carry out it twice,BendibujoDry type transformer applications, and then draw the oil sample.
When sampling in bulk gasoline barrels, samples shall be selected according to 5% of the number of gasoline barrels, but not less than 2 barrels. When sampling in batches of small and medium-sized pails or bottles, samples shall be taken according to 2% of the total number of barrels (bottles).
Manufacturing process and steps of dry-type transformer
The hanging core of dry-type transformer is a vital part
Visual inspection method for transformer inspection
Dry type transformer manufacturer
Test method.When we apply oil immersed 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?
The cross-sectional wiring of transformer input and output power plugs shall comply with the provisions of their current size; It should be equipped according to the current intensity of 2-5A / Min2.
(II) the height width ratio of dry-type transformer pier installed on the ground is generally 0.5m, and a guardrail of no less than 7m shall be installed around it, and a warning sign shall be hung at a prominent position.
The power transformer is designed according to the temperature protection scheme. The embedded parts in the material layer of high (low) pressure electromagnetic coil poured with integral concrete are provided with longitudinal ventilation duct, 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 the output capacity can be increased by 20%.
Production department.Careless maintenance and insulation damage
Two point grounding device of iron core caused by residual welding scar;
The noise of dry-type transformer belongs to low-frequency noise. In a small area, 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.

After tightening the loose bolts, seal the flange, and solve the bolts that are likely to leak,BendibujoVoltage transformer, so as to achieve the goal of complete treatment. Tighten the loose bolts strictly according to the actual operation and processing technology.
When using the oil sample of the power transformer in operation, it is necessary to add some oil from the oil gate valve at the lower part of the oil tank or the sampling gate valve to release about 2kg of waste liquid stored at the bottom to clean the oil inlet, and then take the oil sample.
