Comira6 kV Tra
ComiraSpecificA 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.
What about oil immersed transformer fire?
Comira.How is the quality level of dry-type transformer compared with foreign countries?
Sound in case of phase failure
.Power transformer manufacturer
What is the wavelength of oil immersed transformer?
Oil leakage at electric welding position
The clock expression is used to indicate the phase difference correlation of the working voltage of the secondary side line. The phasor of the working voltage of the primary side line is used as the minute hand, the fixed finger is at 12 o'clock, and the phasor of the phase voltage of the secondary side is used as the second hand.
The insulation of the through core anchor bolt clamping the iron core is damaged, resulting in a short circuit fault between the silicon steel sheet of the iron core and the through core anchor bolt;
Protective measures for damping of dry-type transformer
Inspection basis.The 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:
Dry type transformer manufacturer
What about oil immersed transformer fire?
The scientific research of power transformer oil is generally carried out according to the way of sampling. What are the common sampling methods and processes?
device management.Equipped with a temperature controller, platinum thermistor (pt10) 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, 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.
Several detection methods for installing transformer
When the manufacturer of the power transformer samples from the automobile oil tank,ComiraHow much is 500KVA box transformer, after opening the sealing cover use the cleaned and dried rubber stopper to the oil. At the same time, and loosen your thumb to make the oil enter the pipe,
Comira.After no-load test run is normal for 24h, it can be transferred to on-load operation, and the load shall be gradually increased from 25%, 50% and 75% by grade.
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.
When we apply oil immersed transformer, we all know that it works with the help of oil. What if the oil immersed transformer is on fire? What countermeasures should we do?
