The hanging core of dry-type transformer is a vital part
Bransco.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,BranscoDry type 1250kva transformer, and S9 series distribution transformers have been used to replace S7 Series. In recent years,BranscoOil immersed transformer 50KVA, 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.
The switching power supply lacks one phase of power;
.Common problems of tap changer of power transformer
For the leakage that has already occurred, find the leakage point first, which can not be ignored. For the position with serious leakage, shovel or sharp punch can be selected. The leakage point can be riveted with special tools for metal materials. After manipulating the leakage, the treatment surface shall be cleaned and tidy. Polymer composite materials are mostly selected for dry consolidation. After dry consolidation, the goal of long-term treatment of leakage can be achieved.
In fact, ground wire is not only a kind of grounding protection. The following describes in detail that ground wire is the general name of grounding system. Ground wire is divided into protective grounding and safety factor grounding device. Among them, safety factor grounding device can be divided into grounding protection,BranscoDry type transformer unit, anti electric shock grounding device and anti electromagnetic wave radiation grounding device. Protective grounding is to use it for loop to make the facilities achieve the grounding wire specified by the function.
Therefore, in the installation process of substation equipment, the lightning rod should be set according to the specific situation to prevent damage to the relay protection dry-type transformer caused by lightning. In addition, in the installation and use process of lightning rod, select reasonable types of lightning rod according to the operation situation to determine that they are in the same situation. In addition, during the installation of lightning rod, please connect all routes as far as possible to prevent other faults.

Oil leakage of cast iron parts
reform.Analysis of common faults of oil immersed transformer:
The raw materials of Fushi blue can be used for bonding, so that the overall oil leakage of the connector can be greatly controlled; If the actual operation is convenient, the metal shell can also be bonded at the same time to achieve the purpose of leakage treatment.
Operation and maintenance management of oil immersed transformer
Oil leakage of heat pipe radiator
Installation material list.In fact, safety factor grounding device can be divided into grounding protection, kW. Active power loss of small capacity transformer: when a pump room is in normal operation, two pumps are started separately, and each pump is driven by 100kW motor, so the usual load is 200 KW, and the capacity utilization rate introduced by the transformer manufacturer is only 34%
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.
Bransco.The bearing capacity of each load is different. Generally, dry-type transformer should operate under rated capacity, while oil transformer has better load working capacity.
When the power transformer operates at full load, it needs a large reactive load. This reactive load shall be provided by the power supply and distribution system. If the transformer volume is too large, it will not only increase the initial project investment, but also make the transformer operate at full load or load for a long time, expand the proportion of full load loss, reduce power factor and increase Internet loss. Such operation is neither economic development nor scientific.
A specific part of dry-type transformer is the hanging core of dry-type transformer. The hanging core of dry-type transformer is a vital component. How to carry out the hanging core?
