Power transformer plant
Soligorsk.When the output power P2 of the transformer is equivalent to the input power P1, the efficiency & ETA; Equivalent, the transformer will not cause loss. But in fact, there is no such transformer. The electromagnetic energy of transformer always causes loss. The key of this kind of loss is copper loss and iron loss. Copper loss refers to the loss caused by the number of turns of transformer coil. When the current has a fever according to the number of turns of the coil, part of the electromagnetic energy changes into energy and is lost. Because the electromagnetic coil is generally wound by copper core wire with insulating layer, it is called copper loss.
If the oil immersed transformer is burned by the cover of the transformer, when the oil immersed transformer fails, open the lower side of the transformer and place an appropriate part. When the oil immersed transformer is on fire, the oil cannot be released to avoid the occurrence of the oil immersed transformer. At the same time, use detection equipment to put out the fire immediately. In order not to expand the hazard, the fire brigade must be notified.
.After sampling, bind the laminated glass stopper firmly with clean paper or cloth to prevent dirt and water from contaminating the bottle stopper.
The power transformer conductor refers to the connecting transmission line between each electromagnetic coil,SoligorskOil immersed experimental transformer, between the electromagnetic coil and the group outlet pipe, and between the electromagnetic coil and the tap changer.
The project cost is different. Compared with the purchase price of capacity transformer the purchase price of dry-type transformer is much higher than that of oil immersed transformer.
Under normal conditions, the operation and maintenance management staff shall improve the safety inspection range of the transformer, and immediately communicate and contact with the on-site project staff in case of any problems, so as to ensure the reliable and stable operation of machinery and equipment.
If the input of dry-type transformer is an alternating switching power supply, its output voltage is directly proportional to the coil turn ratio of the output input solenoid coil. If a rechargeable battery is used, because it is DC, add a circuit in the input power supply circuit to change it into a continuously changing voltage. In that way, the alternating DC current can be obtained at the output end.
After 24 hours of continuous trial operation with a certain load,SoligorskPower transformer picture, the main body and accessories of the transformer are all normal, and the transformer will turn to all normal operation.
Quality management.The long-term overload of power transformer will slowly cause the scalding and insulation aging of solenoid coil, 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.
The no-load impulse closing working voltage shall not exceed 5% of the working voltage marked on the gear of the transformer, the closing frequency shall be 5 times, the delay time after power receiving shall not be less than 10min, and the time interval of each closing shall not be less than 5min.
What about oil immersed transformer fire?
According to the condition of cracks, galvanized iron wire can be punched into the leakage or riveted with hammer. Then clean the leakage point with toluene and seal it with raw materials. Coated sand casting eyes can be sealed with raw materials immediately.
Safety and health.The key reason for oil leakage is that there are defects in cast iron parts
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, which promotes the internal molecular structure of the ferrite core to interact with each other its orientation and size change with the change, releases energy, which is the hysteresis loss. The other is the vortex loss when the transformer is working.
Oil leakage of heat pipe radiator
Soligorsk.After sampling,SoligorskPicture of power transformer, effectively deal with various faults of oil immersed transformer, 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, and short-circuit fault is more general.
When oil samples are used, the safety and fire safety technical specifications on the spot shall be strictly implemented.
