What should be considered when lifting the transformer oil tank? For transformers with flat covers, when conducting maintenance on the body, it is essential to use lifting equipment with a capacity greater than the weight of the body to hoist it for inspection. To facilitate user maintenance without large lifting equipment, for bodies weighing 15 […]
How does coastal environment affect the operation of transformers? In coastal areas, the air contains salt spray, which impacts the creepage of bushings and leads to metal corrosion. To express the required leakage ratio for bushings, an equivalent salt density can be used, and the corresponding values are listed in the leakage ratio. Equivalent salt
How does environmental pollution affect the operation of transformers? Pollution can impact the surface discharge strength and surface paint of bushings, and it’s possible to choose bushings with a certain leakage ratio based on different pollution levels. According to national standards, there are several leakage ratios available for selection: Level 0: 14.8mm/kV Level I: 16mm/kV,
The Role of Single Point Grounding of Iron Core and the Anomaly of Multiple Point Groundings In the electrical and electronic industry, the application of ground protection is very important. Iron core single point grounding is the most commonly used ground protection method, which requires a special grounding bar and appropriate grounding resistance to be
Causes and Measures of Winding Short Circuit The winding short circuit will cause serious damage to the motor and other electrical equipment. In order to prevent the occurrence of winding short circuit accidents and ensure the safe operation of electric motor, it is necessary to understand the causes and corresponding preventive measures in depth. First
Types and Characteristics of Commonly Used Insulation Materials Insulation materials play an important role in the electrical and electronic industry. With the development of industry, various types of insulation materials have emerged. Here we list the types and characteristics of the most common insulation materials. 1. Polyvinyl Chloride (PVC): PVC is a kind of general
What is the relationship between transformer insulation level and temperature rise standard？ Insulation level and temperature rise: The insulation level of a transformer refers to the maximum allowable temperature rise, which is the heat resistance level of the insulation material used in the transformer. The temperature rise, on the other hand, refers to the temperature
What is the difference between foil winding and wire winding in transformers? Foil winding refers to the winding made by winding aluminum foil or copper foil, and one turn is one layer. Foil winding is suitable for low voltage, high current transformer.Wire winding means winding with one or more wires in circles, mainly used for
What is the differences between Shell-Type and Core-Type Transformers Transformers are essential devices in the transmission and distribution of electrical power. They are used to step up or step down voltage levels as required in various applications. The two most common types of transformers are the shell-type and core-type transformers. The primary difference between these
The Reason behind Laminating Silicon Steel Sheets in Power Transformers Silicon steel sheets are widely used in the manufacturing of power transformers due to their low magnetic losses. These sheets are made by rolling steel into thin sheets and then laminating them to reduce eddy current losses. The process of laminating silicon steel sheets is
