Oil leakage of porcelain pot and laminated glass oil level gaugeThe insulating layer in the middle of the silicon steel plate is aging the anchor bolt cover with the iron core is damaged, the iron core causes large vortex, resulting in heat, temperature rise, and the aging of the insulating layer is accelerated. The core insulation compressive strength of power transformer must be measured on time and accurately. If it is found that the insulation compressive strength is less than the index value, please remove and replace the anchor bolt cover or carry out insulation for the copper core cable.Izygum,The visual inspection method is that the staff use human eyes to observe the appearance change of the visible parts of the operating equipment to find the abnormal conditions of the equipment, such as discoloration, deformation, cracking, ignition smoke, oil leakage, broken strand disconnection, short-circuit fault marks, hanging of dirty things, etching and turbidity which can be inspected according to the visual inspection method. Therefore, visual inspection is one of the common methods of equipment inspection.Connection group structure of dry-type transformerSidi Aissa,Solenoid insulation deteriorationThe hanging core of dry-type transformer is a vital partCareless maintenance and insulation damage

On load commissioning:Transformer inspection nose sniffing methodPower transformers are also used for testing, which are called test power transformers. They can be divided into inflatable, 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.system,In specific daily life, oil immersed transformers are released outward in the form of waves. This kind of wave is like a tide. It is also a kind of kinetic energy. In fact, the wave height of oil immersed transformer also shows the size of kinetic energy. Generally, computer automatic system is used to control the wavelength and frequency of electromagnetic wave. The longer the light wavelength is, the greater the output power is. On the contrary it is very small.Due to careless transportation of the transformer and the thin high-voltage conductor, the transformer was disconnected by vibration (but there was no grounding device).Method and process of taking oil sample of power transformer

Therefore, in the operation prevention and regulation of relay protection dry-type transformer, it is necessary to find the short-circuit fault point according to the fault situation, lock the fault point, and analyze the short-circuit fault types of relay protection dry-type transformer. At the same time, if all fields are clear, disconnect the switching power supply at the fault point, the maintenance work of employees will be carried out smoothly, and the harm will not expand to a greater extent.Product range,It is generally made due to unreasonable installation or ineffective sealing. Polymer composite materials can bond metal materials, porcelain, laminated glass and other materials very well,IzygumDry type transformer insulation material, so as to achieve the pressure management of oil leakage.How to make up oil for oil immersed transformer?() the installation position of secondary commercial insurance of transformer on column and ground shall meet the following requirements: if there is an disconnector on the secondary side, it shall be installed between the disconnector and low-voltage composite insulator,Izygum630 oil immersed transformer, 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, and the insulated cable jumper shall be connected to the insulated cable on both sides of the circuit breaker.Izygum,IzygumPower transformer maintenance contract,From the appearance, and only the shell can be seen for oil immersed transformer;The main reason is that the welding quality of electric welding is poor, there are empty welding, open welding, needle holes, sand holes and other shortcomings in welding. The oil transformer is easy to be covered with welding powder and paint when leaving the factory, and the potential safety hazards are exposed after operation. In addition, the electromagnetic induction vibration will crack the electric welding and lead to leakage.Dry type transformer manufacturer
