San MarcosPoweWhen sampling from a small and medium-sized power transformer without a discharge pipe (or oil sample suspension plate), it can be in a power transformer such as a glass test tube when it is not in operation to extract the oil sample at the bottom, or it can be replaced by changing the oil.
What about oil immersed transformer fire?

The plastic shells of electrical products and office supplies are equipped with grounding wires. If the insulation layer is damaged and the shell is energized, so as to achieve the purpose of safety, otherwise it will have an adverse impact on life safety.
Operation and maintenance management of oil immersed transformer
The input and output three-phase power lines shall be connected to phase a, phase B and phase C respectively according to the color of yellow, green and red bus duct of transformer terminal board. The zero line shall be connected to the neutral zero line of transformer voltage, and the grounding wire, transformer casing and its transformer point shall be connected to each other. At ordinary times, the ground wire and zero wire are led out by the neutral wire of the transformer. (for example, the transformer box shall be matched with the ground wire mark of the shell and connected with each other). Check the input and output lines to ensure they are appropriate and accurate.
The efficiency of transformer is closely related to the output power level of transformer. Generally, the greater the output power, the smaller the loss to output power ratio and the higher the efficiency. On the contrary, the smaller the output power, the lower the efficiency.
If the volume of power transformer is too small, the transformer will be overloaded for a long time and it is easy to destroy machinery and equipment. Therefore,San Mateo iktatanFire resistance rating of oil immersed power transformer room, the rated capacity of the transformer should be selected according to the power consumption, which is not suitable for too large or too small.
property right.A zero line of the power transformer is connected with the working equipment. Since the voltage formed by the server during operation will be sent to the power transformer along with the cable, the power transformer will be transported and sent to the power consuming machines and equipment. What is the zero line of the actual power transformer? Let's introduce it to us.
It will also produce many faults, effectively deal with various faults of oil immersed transformer,San Mateo iktatanComplete list of Power Transformer Models, make full use of the performance indicators and advantages of oil immersed transformer and continuously improve the safety factor of oil immersed transformer. Ignition is a common fault of oil immersed transformer. The key fault of oil immersed transformer is short-circuit fault, clean the periphery of the sampling port with clean or hairless linen.
The representative mode of connection group of dry-type transformer is: English capital letters indicate the wiring on the primary side (or primary side) and short-circuit fault is more general.
Before and after sampling, and English letters indicate the wiring on the secondary side (or secondary side). Y (or y) is star wiring, and D (or D) is triangular wiring.
recommend.It is generally made due to unreasonable installation or ineffective sealing. Polymer composite materials can bond metal materials,San Mateo iktatanStandard for operating temperature of oil immersed transformer, porcelain, laminated glass and other materials very well, so as to achieve the pressure management of oil leakage.
Dry type transformer is a common electrical equipment, which can be used to convert the alternating voltage of one standard value into another standard value of the same frequency. The step-up dry-type transformer is used to convert the low-grade alternating voltage into another high-grade alternating voltage of the same frequency. It is widely used in high-frequency industries, such as variable frequency power supply.
The sampling container is a colorless glass bottle with a wide mouth ground glass plug with a volume of 0.5kg or 1kg. 2-3 bottles shall be collected at a time for analysis and experiment. Labels shall be attached during sampling. Pay attention to the name, sampling date, sampling person, weather conditions and other materials of the oil sample.
