Transformer installation method steps and procedures
The transformer can be directly thrown into the transformer room by car crane, or set up a temporary track with wood, with three steps, chain crane to the temporary track, and then pull the chain into the appropriate position indoors. The transformer should pay attention to its orientation and distance from the wall size in accordance with the drawing, the allowable error is ±25mm, the horizontal distance from the wall should not be less than 800mm, the distance from the door should not be less than 1000mm when the drawing is not marked. Installation of transformer bench: the transformer is i
The difference between dry type transformer and oil immersed transformer
The difference between dry type transformer and oil immersed transformer is [Xuzhou transformer manufacturer] different appearance, packaging form Dry type transformers can see the core and coil directly, while oil immersed transformers can only see the transformer shell. [Xuzhou transformer manufacturer] lead form is different Dry-type transformers mostly use silicone rubber casings, while oil-immersed transformers mostly use magnetic casings.
High voltage transformers are commonly divided into two types of oil-immersed transformers of dry type transformers. Xuzhou transformer manufacturer briefly introduced the basic characteristics of dry type transformer and oil-immersed transformer: Xuzhou transformer manufacturer - the price of dry type transformer is higher than oil - immersed transformer Oil - immersed transformer than dry - type transformer capacity Xuzhou transformer manufacturer - different use space
Xuzhou transformer manufacturer introduces the main components and functions of the transformer
The basic structural components of transformer are composed of iron core, winding and insulation. In addition, fuel tanks, refrigeration equipment, and maintenance equipment were installed for reliable operation. Core: The core of the transformer is the path of the magnetic field line, which has the effect of concentrating and strengthening the magnetic flux, and is used to support the winding together. Winding: the winding of the transformer is the path of the current. The current is connected through the winding and the induced EM
Oil system analysis of oil-immersed transformer
Oil-immersed transformers have several separate oil systems. During the operation of oil-immersed transformers, the oils in these oil systems are not connected to each other, and the oil quality and operating conditions are different. Chromatographic analysis of the gas in the oil should be performed separately to identify potential problems. Oil in the high pressure outlet box or oil in the gas outlet box. The high voltage outlet of the three-phase 500kV transformer passes through the corrugated insulation and oil isolation system. The main function of this oil
Dry-type transformer factory explains why pebbles need to be placed under the transformer
We can often see that a large number of pebbles are placed under some transformers, so what are these pebbles for? Is it just for aesthetics? Dry transformer factory to explain to you. This part under the transformer is generally called the oil discharge pool or the oil discharge pit (or similar name), leading to the oil pit or the oil pool. When there is an accident, such as oil injection, the oil of the transformer will be discharged into the oil discharge pit, and then flow to the oil pool. Some in the pool do the barrier, some do not do the barrier. To make a
How to maintain oil-immersed power transformer?
The protection and maintenance of oil-immersed power transformer has always been a problem that many transformer users urgently need to understand. Although dry type transformer has advantages over oil-immersed transformer, the protection and maintenance of oil-immersed power transformer is proper, which also has its own unique advantages. So, oil-immersed power transformer in the protection and maintenance of the need to pay attention to what methods? Tianhong Power technology for you! What are the protection and maintenance methods of oil-immersed power transfo
Dry-type transformer manufacturer-standard for inspection of operation of power transformers
Power transformer inspection mainly checks the remaining oil, oil color and oil temperature, to see whether the quality of the oil is guaranteed, to see whether it has long appeared oil leakage. Second, to check, to see whether the appearance of the power transformer has changed, if the deformation of the early time, to immediately stop using. Finally, to see whether the sound of the power transformer is normal when it is in operation, it is necessary to pay more attention to the sound of the machinery and equipment at ordinary times, because the sound of the machinery and equipment can reflec
How to do the daily maintenance work of 35kv dry type transformer
35kv dry type transformer also needs to be maintained in use, so that the dry type transformer can get better results and make the performance of dry type transformer better. Dry type transformer maintenance is generally once a week or twice, 35kv dry type transformer maintenance should pay attention to the problems are more, so the common 35kv dry type transformer maintenance to do what aspects? How to do the daily maintenance work of 35kv dry type transformer: 1. Basic requirements High pressure maintenance personnel should hold a certificate to w
What are the key parts of dry transformer
The structure of dry transformer is very complex, and the characteristics and effects of dry transformer are also carried out with the help of the important parts of dry transformer, so it is important to figure out the role of the important parts of dry transformer. 1. Winding resistance (alias coil) It is generally made of insulated flat copper core wire or round copper core wire wound on the winding die. Chongqing dry type transformer factory includes primary, secondary (high pressure, bottom pressure)2 groups. The primary coil is to transfer the electrical ene
What are the causes of spontaneous combustion of power transformers
I. There is no commercial insurance on both sides of high and bottom voltage of distribution transformer. Although some have already installed drop type fuse and shofar commercial insurance, but its fuse is mostly aluminum or copper wire replacement, resulting in the bottom voltage short circuit fault or load, fuse can not all normal melt and burn the transformer. The high and low fuses of distribution transformers are not well equipped. The fuse on the transformer is generally equipped with too much, which leads to the burning of the transformer when the distribution transformer is heavily lo
What function does the power transformer anti-theft alarm system have?
The power transformer anti-theft alarm system is mainly used in the power distribution network power line, transformer and other distribution equipment and routes of the power supply system to prevent breaking, theft and destruction. The server adopts the sealed aluminum alloy die-casting shell, with good moireproof characteristics, easy to use, stable and reliable in work and other characteristics, into the countryside of a variety of natural environment application, power transformer is widely used in power engineering, crude oil, min
What are the fire prevention measures of 35kv dry type transformer?
With the arrival of high temperature weather, in order to reduce the occurrence of fire, we should always do a good job in the use of 35kv dry type transformer fire prevention measures. The operation of 35kv dry type transformer is based on transformer oil as the medium, and there will be oil leakage in the operation of 35kv dry type transformer, and serious oil leakage will lead to fire. Therefore, in order to ensure the safety of 35kv dry type transformer operation, it is necessary to do a good job in the relevant fire prevention meas
Key technologies and measures for energy saving and consumption reduction of transformers
Because of the distribution transformer and its power supply and distribution system, the proportion of single-phase electricity load is relatively heavy, and with the wide use of various energy-saving electrical equipment and energy-saving lamps, the three-phase load imbalance of distribution transformer is large, resulting in large losses, which shows that the load loss caused by the three-phase imbalance is very large. Through reasonable phase load optimi
