AldenzarPower transformer 2With filtering performance in the industry

first take out the low-voltage waterproof sleeve and the on load transformer power switch, then lower the bell cover anchor bolt of the large cover, slowly hang the galvanized steel wire rope with sufficient lifting net weight on the commonly used earrings, wear 4 round steel from top to bottom in the surrounding screw holes, and count the spacing and specifications for easy reinstallation. At the same time the cable wind shall be added on all sides to ensure that the core international body will not be damaged during the whole lifting process. After lifting for 100mm, stop the lifting, stabilize the bell cover, and check the bearing capacity of the lifting core, center of gravity and Jack. After everything is normal, lift it again until the bell cover exceeds the relative height of the body and rotate the crane to place the bell cover on the clean skid.

(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,AldenzarHow much is the price of 250kVA box transformer, a spacing of more than 2m shall be reserved; If metal fence is selected, the metal fence shall be grounded and a warning sign shall be hung at a prominent position.

Aldenzar.At rated power, i.e. & ETA; Is the efficiency of the transformer; P1 is the input power and P2 is the output power.

Fault judgment of power transformer

.The manufacturing process of dry-type transformer is very process, and must be technically as a certain pillar. Only in that way, or between electromagnetic coil, iron yoke clamp and automobile oil tank wall. Therefore, it is necessary to ensure that this kind of conductor has sufficient insulation compressive strength, i.e. insulation spacing.

& ldquo; of wiring transformer; Enter & rdquo; And & ldquo; Output & rdquo; Use a megger to test the grounding resistance between the terminal and the ground wire. When accurately measured by 1000V megger,AldenzarPrice of 1000 KVA dry type transformer, the resistance value exceeds 2m ohm bus.

With the rapid development of society and the continuous development trend of computers, the calculation of data in the whole process of oil immersed transformer wave has long had results. Only effective selection of calculation entity models and methods is needed, the accuracy of calculation conclusions can meet the needs of architectural design, and scientific and reasonable data method is selected,AldenzarPrice of dry-type transformer, Not only can the current distribution of the oil immersed transformer be clearly defined in the development stage, but also the winding and other structures of the oil immersed transformer can be effectively arranged and distributed in a certain scope, which greatly facilitates the design scheme of the oil immersed transformer and ensures the stability of operation.

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, 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.

Caused by sand holes and cracks. For crack leakage, drilling stop hole is a good way to remove in-situ stress and prevent widening.

Sincere service.After 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.

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, which can be equipped with air-cooled machinery and equipment (cooling centrifugal fan). After selecting air-cooled machinery and equipment, the output capacity can be increased by 20%.

In specific daily life, we have a certain understanding of the optical wavelength of oil immersed transformer. What kind of function does it have for transformer?

Noise pollution control and prevention measures of dry-type transformer

how.Some are tied with plastic tape, and some immediately press the two edges together, because the socket can not be pressed firmly during installation, and there is still oil leakage without sealing effect.

Transformer is

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.

Aldenzar.The vibration reduction of the grounding device sheet solves the problem of modifying the fixed hard connection between the copper sheet of the grounding device and the dry-type transformer. The original oscillation of the dry-type transformer will be transmitted to the metal in the concrete by the baffle and cause low-frequency noise. Therefore, it must also be changed to produce flexible connection.

A zero line of the power transformer is connected with the working equipment. Since the voltage formed by the server during operation will be sent to the power transformer along with the cable, the power transformer will be transported and sent to the power consuming machines and equipment. What is the zero line of the actual power transformer? Let's introduce it to us.

High voltage fuse of transformer breaks one phase;
