KovoraDry type
KovoraPrice ofAfter no-load test run is normal for 24h, it can be transferred to on-load operation, and the load shall be gradually increased from 25%, 50% and 75% by grade.
It is generally made due to unreasonable installation or ineffective sealing. Polymer composite materials can bond metal materials porcelain, laminated glass and other materials very well, so as to achieve the pressure management of oil leakage.
Kovora.When the operating oil is mixed with different types of new oil or used for oil, in addition to the accurate measurement of the cold filter point of the mixed oil, it is also necessary to carry out high and low temperature test and sludge test, and observe the sludge accumulation. The accumulation cannot be accessed. The results of the operation of the mixing template are not that the original oil is very poor, so it can be managed and used in a mixed manner.
When oil samples are used,KovoraMaximum capacity of box transformer, the safety and fire safety technical specifications on the spot shall be strictly implemented.
.Power transformer factory
The power transformer belongs to relatively durable electrical equipment, The resistor is generally more than 2000 & omega; power transformer winding and power transformer tapping power switch are analyzed below:
Operation of oil immersed transformer
The technical specification of power consumption requires that the resistance of maintenance grounding wire shall be ≤ 4Ω, According to Ohm's law, when the insulating layer is damaged, the current is only 1 / 500 of the total current flow, so as to play a guarantee effect. The higher the voltage, the smaller the resistance, in other words, in the case of high voltage. We can care about the power transformer plant and master a lot of professional knowledge.
The common dry-type transformer is an important electrical equipment, and the voltage is constantly regulated. However, because of certain necessity the dry-type transformer will also boost voltage, and the whole process of boosting voltage is very complex, clearly put forward the glass test tube, rotate and release the oil in the tube to clean the sampling tube,KovoraPower plant step-up transformer, carry out it twice, and then draw the oil sample.
Sincere service.The switching power supply lacks one phase of power;
In specific daily life, connect the data signal contact of the automobile relay with the alarm circuit, the pull-in contact with the opening circuit, and adjust the overcurrent protection value.
Sound insulation treatment of main engine room the key to sound insulation treatment of dry-type transformer room is to start from three levels: window, ventilation and air exchange port and road surface, and apply sound insulation window, silencing cylinder, floating concrete floor damping pad and other sound insulation and noise reduction commodities to achieve sound insulation effect.
Product range.Before application, the sampling container shall be cleaned with vehicle gasoline, soapy water or other organic solvents (such as trisodium phosphate) except oil stains, and then washed with tap water until it is not alkaline, and the water can be evenly distributed from the bottle, and then cleaned with purified water for many times. The cleaned sampling container shall be dried in a 105 ℃ drying oven. After refrigeration,KovoraDry type transformer production video, the bottle cap shall be tightly closed and cannot be opened before application.
The transformer manufacturer shall not use hand touch method to detect energized high-voltage equipment, such as transformer in operation and neutral grounding equipment of arc suppression coil. For the equipment without power supply and whose shell is reliable grounding device, 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.
In order to better carry out the experiment of power transformer oil, it is necessary to sample the power transformer oil. The sampling work should be carried out on a dry sunny day. The commonly used containers and sampling methods during sampling do immediate harm to whether the specific quality of the oil can be truly reflected. The oil sample for AC voltage withstand test shall not be less than 0.5kg, and the oil sample for simplified experiment shall not be less than 1kg.
Kovora.Loose core screw
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 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:
