Operation and maintenance management of oil immersed transformer
Sound insulation treatment of main engine room the key to sound insulation treatment of dry-type transformer room is to start from three levels: window, and apply sound insulation window, silencing cylinder, floating concrete floor damping pad and other sound insulation and noise reduction commodities to achieve sound insulation effect.
Guntour.What is the cause of power transformer core failure?
When using the oil sample of the power transformer in operation, it is necessary to add some oil from the oil gate valve at the lower part of the oil tank or the sampling gate valve to release about 2kg of waste liquid stored at the bottom to clean the oil inlet and then take the oil sample.
.Fault judgment of power transformer
Oil leakage of cast iron parts
When using the oil sample of the power transformer in operation,GuntourOil immersed transformer thermometer, it is necessary to add some oil from the oil gate valve at the lower part of the oil tank or the sampling gate valve to release about 2kg of waste liquid stored at the bottom to clean the oil inlet, and then take the oil sample.
The method and whole process of taking oil sample of power transformer are as follows:
Oil sample inspection & mdash; & mdash; the performance parameters such as compression resistance and residue shall be carried out every three years. The long-term overload or overload of the transformer can reduce the cycle time.
The long-term overload of power transformer will slowly cause the scalding and insulation aging of solenoid coil,GuntourWhat is the price of 1600KVA transformer, resulting in short circuit between coils, two-color short circuit or short circuit on the ground, resulting in the ignition of power transformer. Therefore, the insulation compressive strength of power transformer shall be tested before installation and operation, and overload is not allowed in the whole process of operation.
Safety and health.For no-load impulse closing of transformer, pay attention to the following matters:
Protective measures for damping of dry-type transformer
Power transformers are used in all walks of life
In fact, safety factor grounding device can be divided into grounding protection, anti electric shock grounding device and anti electromagnetic wave radiation grounding device. Protective grounding is to use it for loop to make the facilities achieve the grounding wire specified by the function.
Excellent quality.From the appearance, the packaging types are different. The transformer core and electromagnetic coil can be seen immediately for dry-type transformer, and only the shell can be seen for oil immersed transformer;
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.
When sampling in bulk gasoline barrels, samples shall be selected according to 5% of the number of gasoline barrels, but not less than 2 barrels. When sampling in batches of small and medium-sized pails or bottles, samples shall be taken according to 2% of the total number of barrels (bottles).
Guntour.Avoid the load operation of power transformer: if the load operation is long-term, it will lead to the scalding of solenoid coil, slow aging of insulation,GuntourHow much is dry test transformer, short circuit fault between boxes, two-color short circuit fault or short circuit to ground fault and dissolution of oil.
The raw materials of Fushi blue can be used for bonding, the metal shell can also be bonded at the same time to achieve the purpose of leakage treatment.
