Oil leakage at looper flangeThe power transformer is designed according to the temperature protection scheme. The embedded parts in the material layer of high (low) pressure electromagnetic coil poured with integral concrete are provided with longitudinal ventilation duct, which can be equipped with air-cooled machinery and equipment (cooling centrifugal fan). After selecting air-cooled machinery and equipment, the output capacity can be increased by %.answer,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.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, short circuit fault between boxes two-color short circuit fault or short circuit to ground fault and dissolution of oil.Bunbury ,After tightening the loose bolts, seal the flange, and solve the bolts that are likely to leak, so as to achieve the goal of complete treatment. Tighten the loose bolts strictly according to the actual operation and processing technology.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, the electric flow will leak into the earth along the installed grounding wires, so as to achieve the purpose of safety, otherwise it will have an adverse impact on life safety.In fact, ground wire is not only a kind of grounding protection. The following describes in detail that ground wire is the general name of grounding system. Ground wire is divided into protective grounding and safety factor grounding device. Among them,answerWhich is a good oil immersed test transformer, 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.

Equipped with a temperature controller, platinum thermistor (pt) is placed beside the embedded hole on the top of the low-voltage solenoid coil to test the winding resistance temperature rise of the transformer, stop the cooling centrifugal fan, set up common problem alarm, overtemperature alarm and overtemperature tripping effect, and provide reliable overvoltage protection machinery and equipment for the dry test transformer, so as to test the safety performance of the transformer operation.The iron loss of transformer includes two levels. The first is the hysteresis loss introduced by the transformer manufacturer. When the AC circuit is based on the transformer, according to the magnetic induction line of the transformer ferrite core, its orientation and size change with the change, which promotes the internal molecular structure of the ferrite core to interact with each other, releases energy, and then loses part of electromagnetic energy which is the hysteresis loss. The other is the vortex loss when the transformer is working.Deterioration damage of transformer core insulationtechnological innovation, resistance to short-circuit faults, common faults and impact. The work is diligent.The vibration reduction of collecting and townhouse solves the soft connection of collecting and townhouse. For the copper bar of the low-voltage bus of the equipment,answer380V to 660V three-phase transformer,answerWhat is the price of 1000 KVA transformer, the electromagnetic induced noise oscillation may be transmitted from the townhouse to the building structure. The core of noise reduction solution must be changed to copper wire connection.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.

Insulation and heat removal are different. Dry type transformers are generally insulated with epoxy resin, cooled by natural air and large capacity by centrifugal fan. Oil immersed transformers are insulated by insulating oil, insulated by insulating oil in the circulating system inside the transformer, and heat is discharged on the radiator (radiator) of the circulating system inside the transformer.Installation requirements, all anchor bolts of the automobile oil tank at the upper end of the detachable oil cover shall be tied with the lifting jack, and the lifting point shall be on the common earrings or bolts. If necessary, the human resources traction belt shall be used as a guide.The grounding resistance of, high voltage and bottom voltage shall not be less than % (m & omega;) of the original value. The difference between the three-phase mean value of winding resistance measurement at the same temperature shall not exceed %, which shall not exceed % compared with the last accurate measurement result.Oil immersed transformer companyanswer, 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.Oil leakage of cast iron partsThe power transformer belongs to relatively durable electrical equipment and we can't neglect it in daily application. The common problems of power transformer conductor, power transformer winding and power transformer tapping power switch are analyzed below:
