Lugoj Dry type transformer controllerWhat are the industry advantages

After the oil is drained, all anchor bolts of the automobile oil tank at the upper end of the detachable oil cover shall be tied with the lifting jack, the human resources traction belt shall be used as a guide.

In order to better reduce the probability of short-circuit fault of relay protection dry-type transformer, prevention and key are & ldquo; Prevention and Manipulation & rdquo; Is dominant.

Lugoj .With Vietnam and Malaysia, China's first UHV transmission experimental demonstration project, China Transformer Corporation has entered a breakthrough in the development trend. The commodity voltage grade and volume rank first in the world occupying the main technical position of the industry development trend. In addition, it has promoted the continuous improvement and perfection of the technology of low-voltage transformers.

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, 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.

.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).

Oil leakage of bolt or pipe external thread

For example, in the 1970s, the radio programs applied by every family in the countryside had a ground wire, and they were often wet with tap water. Protective grounding is to bury the copper plate of metal electrical conductor in the soil layer, and then lead a point of it out of the road with transmission line, office and other electrical equipment.

How much is the power transformer

How to maintain dry-type transformer?

The input and output three-phase power lines shall be connected to phase a, green and red bus duct of transformer terminal board. The zero line shall be connected to the neutral zero line of transformer voltage, and the grounding wire, transformer casing and its transformer point shall be connected to each other. At ordinary times, the ground wire and zero wire are led out by the neutral wire of the transformer. (for example, the transformer box shall be matched with the ground wire mark of the shell and connected with each other). Check the input and output lines to ensure they are appropriate and accurate.

Marketing Department.For example, in the 1970s,Lugoj Dry type transformer scb14, the radio programs applied by every family in the countryside had a ground wire, and they were often wet with tap water. Protective grounding is to bury the copper plate of metal electrical conductor in the soil layer, and then lead a point of it out of the road with transmission line, which completes the grounding protection. The grounding wire specifies the grounding wire resistance ≤ 4Ω. Grounding protection is a safeguard measure adopted to avoid safety accidents when using household appliances, office and other electrical equipment.

Falling foreign matters and piercing

Then clamp the branch pipe with your thumb,Lugoj Three phase transformer 100kW,Lugoj Insulation grade of oil immersed transformer, clearly put forward the glass test tube, rotate and release the oil in the tube to clean the sampling tube, carry out it twice and then draw the oil sample.

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.

technical service.Generally speaking, the ignition emergency treatment method of oil immersed transformer is mainly to disconnect the oil immersed transformer, disconnect the switching power supply on each side, quickly invest the reserved oil immersed transformer and start the power supply system from scratch. Stop the operation of refrigeration equipment. Key oil immersed transformer ignition. When L-type oil immersed transformer and high voltage station oil immersed transformer are ignited the generator set must be disassembled first.

This is the example of power consumption engineering as power saving. The key reason is that the habitual calculation method ignores the copper loss.

If you want to check the activated carbon fiber for the hanging cover, 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, stop the lifting 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, 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.

Lugoj .In the case of using dry-type transformer, customers must master the method of wiring. If there are problems in wiring, it is easy to cause common faults in application. So, what is the wiring mode of dry-type transformer?

The flange surface is uneven, the tightening bolts are loose, and the installation and processing process is wrong, so that the bolts are not tightened well, resulting in oil leakage.

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.
