The Czech RepublicHow to select power transformerHow to provide service guarantee

Power transformers are also used for testing, which are called test power transformers. They can be divided into inflatable,The Czech Republic630kVA dry type transformer, oil transformer, dry test and other test power transformers. They are the basic test equipment for communication AC compression test for many consumers such as power stations, power supply bureaus and scientific research institutions. According to the specifications of the Bureau of quality supervision, It is used to carry out insulation compressive strength test under required current for various electrical products, electrical components and insulating raw materials.

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

The Czech Republic.Power transformer is indispensable for power stations and substations, but we must pay attention to many problems in the whole process of applying power transformer.

Power transformer is an idealized supporting facility transformer for medium cabinet and high-voltage cabinet at the present stage, and can be equipped with safety protective casing according to different waterproof grades. It is applicable to key or unique natural environment sites such as multi-storey buildings, commerce, airports tunnel construction, chemical enterprises and factories.

.The noise of dry-type transformer belongs to low-frequency noise. In a small area, most of it is scattered according to the building structure. This kind of low-frequency noise is scattered to the household house according to the house building, and then causes gas vibration noise, which is then scattered to the ears of consumers. Although the amount of noise is not very large, the dispersion spacing and adverse effects are very large.

The tail end of the high-voltage winding head and the middle tap are made of copper inserts and embedded parts, with good strength and stiffness, which is conducive to adjusting the data and has a unique and neat style.

The power transformer belongs to relatively durable electrical equipment, and we can't neglect it in daily application. The common problems of power transformer conductor,The Czech RepublicFully sealed oil immersed transformer, power transformer winding and power transformer tapping power switch are analyzed below:

After the power transformer has been used for a long time, common faults of iron core will occur. Don't worry. Contact the transformer manufacturer,The Czech RepublicThree phase power transformer, and the manufacturer will assign professional technicians for inspection. The main reasons are as follows:

Note: in the whole process of safety patrol inspection, the on-site operation and maintenance management staff must use temperature tester or thermal imager to carry out purposeful inspection on the transformer itself terminal block and other accessories; The sound during the operation of the transformer is a symmetrical current sound. If the sound is found to be abnormal, significantly expanded, or there is local sound, the cause shall be found immediately and certain effective measures shall be taken. If necessary, it shall be installed between the disconnector and low-voltage composite insulator, or the circuit breaker shall be selected as the disconnector; If there is no disconnector on the secondary side, it shall be installed on both sides of the low-voltage composite insulator, prevention and key are & ldquo; Prevention and Manipulation & rdquo; Is dominant.

Sales Department.The vibration reduction of collecting and townhouse solves the soft connection of collecting and townhouse. For the copper bar of the low-voltage bus of the equipment, the electromagnetic induced noise oscillation may be transmitted from the townhouse to the building structure. The core of noise reduction solution must be changed to copper wire connection.
