Aksay Model anconnect 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.
Umhajer.The transformer manufacturer said that the selection should be based on the application environment of the dry-type transformer. For the extremely extreme environment, the dry-type transformer should be poured with epoxy resin glue. Because this kind of environment does not need to heat the dry-type transformer, it can operate immediately. However, for the general application environment, the class H dry-type transformer can be used.
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, the bottle cap shall be tightly closed and cannot be opened before application.
.Wiring mode of dry-type transformer:
Dry type transformer manufacturer
(I) the distance between the external contour of 10kV and below dry-type transformer and the surrounding guardrail or courtyard wall shall take into account the convenience of transportation and repair of dry-type transformer, and the distance shall not be less than 1m; At the angle with actual operation, the metal fence shall be grounded and a warning sign shall be hung at a prominent position.
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?
It is understood that in China, transformers have experienced the whole process of replacing many series products such as sss11. As early as the middle and late 1980s, S7 Series lossless distribution transformers were selected in China to replace the high energy consumption transformers of jb1300-73 and jb500 - Specifications operating in the power network at that time. Since the 19th century, urban power grids have been transformed all over the country,UmhajerHow much is a 250kVA box transformer, and S9 series distribution transformers have been used to replace S7 Series. In recent years, S13 and S15 commodities are gradually selected in large quantities in the transformation of urban and rural power networks in China, and their full load loss is 50% - 80% less than that of S9 transformer.
There are also many problems to pay attention to in the preventive measures and process of dry-type transformer damping. What are the key effects and functions of dry-type transformer damping and the corresponding preventive measures? Let's master and consult in detail with the small editor of the dry-type transformer manufacturer.
Management Department.When the transformer is out of phase, if the second phase is blocked, there is still no sound when the second phase is sent, and there is sound when the third phase is sent; If the third phase is blocked,UmhajerParameters of 1250kva oil immersed transformer, the sound will not change, as in the case of the second phase. There are three reasons for phase deficiency:
Insulation and heat removal are different. Dry type transformers are generally insulated with epoxy resin, cooled by natural air and large capacity by centrifugal fan. Oil immersed transformers are insulated by insulating oil, insulated by insulating oil in the circulating system inside the transformer, and heat is discharged on the radiator (radiator) of the circulating system inside the transformer.
Equipped with a temperature controller, platinum thermistor (pt10) is placed beside the embedded hole on the top of the low-voltage solenoid coil to test the winding resistance temperature rise of the transformer,UmhajerDistribution transformer maintenance, stop the cooling centrifugal fan, overtemperature alarm and overtemperature tripping effect, and provide reliable overvoltage protection machinery and equipment for the dry test transformer, so as to test the safety performance of the transformer operation.
The project cost is different. Compared with the purchase price of capacity transformer the purchase price of dry-type transformer is much higher than that of oil immersed transformer.
Equipment maintenance.Sound in case of phase failure
The fundamental reason for this kind of inaccuracy is that when the transformer & ldquo; Dalar trolley & rdquo; is considered according to the size of capacity utilization rate, the high-capacity transformer must be replaced by the small-capacity transformer with high utilization rate, and then the iron loss is considered and the copper loss is ignored. In fact for a certain load, so it consumes electromagnetic energy.
In specific daily life the active power loss of small capacity exceeds that of large capacity The active power loss of the transformer, we have a certain understanding of the optical wavelength of oil immersed transformer. What kind of function does it have for transformer?
Umhajer.What is the wavelength of oil immersed transformer?
When the manufacturer of the power transformer samples from the automobile oil tank, after opening the sealing cover, use the cleaned and dried rubber stopper to the oil. At the same time, clamp the branch pipe with your thumb, and loosen your thumb to make the oil enter the pipe,
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).
