Avoid the load operation of power transformer: if the load operation is long-term,Annette SharonOil immersed transformer temperature, it will lead to the scalding of solenoid coil, short circuit fault between boxes, two-color short circuit fault or short circuit to ground fault and dissolution of oil.

Dry type transformer manufacturer

Annette Sharon.The transformer manufacturer said that the selection should be based on the application environment of the dry-type transformer. For the extremely extreme environment, the dry-type transformer should be poured with epoxy resin glue. Because this kind of environment does not need to heat the dry-type transformer, it can operate immediately. However, for the general application environment, the class H dry-type transformer can be used.

The raw materials of Fushi blue can be used for bonding, so that the overall oil leakage of the connector can be greatly controlled; If the actual operation is convenient, the metal shell can also be bonded at the same time to achieve the purpose of leakage treatment.

.Caused by sand holes and cracks. For crack leakage, drilling stop hole is a good way to remove in-situ stress and prevent widening.

Gradually, high-frequency vibration damping mechanical equipment, such as low-frequency vibration damping platform, is installed at the bottom of the dry-type transformer, roads, etc. with flexible connection or use elastic yellow shock absorption mechanical equipment to prevent the vibration from spreading according to the rigid connection. If possible, the dry-type transformer room can also be soundproofed and decorated, and sound-absorbing plates and silencing shutters can be used to improve the soundproofing capacity of the dry-type transformer room.

What is the cause of power transformer core failure?

Solenoid insulation deterioration

Management Department.Then clamp the branch pipe with your thumb, clearly put forward the glass test tube, rotate and release the oil in the tube to clean the sampling tube, carry out it twice, and then draw the oil sample.

The voltage regulating tap changer is not in place or poor

During no-load test run, the transformer shall be connected with the working voltage from the switching power supply side, and then make the working voltage impulse closing.

production.Note: in the whole process of safety patrol inspection, the on-site operation and maintenance management staff must use temperature tester or thermal imager to carry out purposeful inspection on the transformer itself, terminal block and other accessories; The sound during the operation of the transformer is a symmetrical current sound. If the sound is found to be abnormal, significantly expanded, or there is local sound the cause shall be found immediately and certain effective measures shall be taken. If necessary, the load can be reduced or the operation of the transformer can be stopped.

This is the example of power consumption engineering as power saving. The key reason is that the habitual calculation method ignores the copper loss.

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, 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.

Annette Sharon.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.
