HuainanNational standard for loss of oil immersed transformerPrinciple of working in the right direction

For example, the radio programs applied by every family in the countryside had a ground wire, and they were often wet with tap water. Protective grounding is to bury the copper plate of metal electrical conductor in the soil layer, and then lead a point of it out of the road with transmission line, which completes the grounding protection. The grounding wire specifies the grounding wire resistance ≤ Ω. Grounding protection is a safeguard measure adopted to avoid safety accidents when using household appliances, office and other electrical equipment.() 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, 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,Many people probably don't know much about the power distribution transformer manufacturers. In fact, the transformer can be plugged in for trial operation after careful inspection before capital investment. During the trial operation period, you must pay attention to the following points. Whether there is abnormal sound,Huainan33kV power transformer, noise and vibration, whether there is abnormal smell such as coke smell, and whether there is discoloration caused by partial overheating. Ventilation is good. In addition, we should also pay attention to the following aspects.When leaving the factory, the production and processing are not smooth and the sealing is poor. The common fault of oil leakage will be caused after the oil transformer is sealed for a period of time.Bela Slatina,The flange surface is uneven, the tightening bolts are loose, and the installation and processing process is wrong,HuainanAll transformers, so that the bolts are not tightened well, resulting in oil leakage.Power transformers are used in all walks of lifeNoise pollution control and prevention measures of dry-type transformer

In relay protection dry-type transformer the disconnection of the fault point is related to each other. In a word, if there is any problem at a certain point, 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.How much does it cost?,Oil immersed transformerThe iron core of power transformer is made of high-quality crystallized hot-rolled ferrite core, which is stacked at the degree fully inclined multi-step interface. The surface is covered with epoxy resin adhesive cable sheath coating, which is resistant to corrosion and rust, and has sound insulation and noise reduction.Plug in the power with full load first, observe and detect that the input and output voltage meets the regulations. At the same time,HuainanModel of dry-type power transformer, check whether the equipment has abnormal sound, ignition, odor and other abnormal conditions. If there is any abnormality,The power transformer is composed of two or more electromagnetic coils wound around the same transformer core. The winding resistance is connected according to the alternating electromagnetic field and works according to the basic principle of magnetic effect of current. The installation position of power transformer shall be considered to be conducive to operationThe scientific research of power transformer oil is generally carried out according to the way of sampling. What are the common sampling methods and processes?Precautions for trial operation of power transformer manufacturersSolenoid insulation deteriorationHuainan, maintenance and transportation, and a reliable area shall be selected at the same time. The rated capacity of the transformer must be effectively used when applying the transformer.After hours of continuous trial operation with a certain load, the main body and accessories of the transformer are all normal, and the transformer will turn to all normal operation.Loose core screw
