It will also produce many faults, effectively deal with various faults of oil immersed transformer,TucsonDry type test 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.
Tucson.Dry type transformer, is used to change the AC current (current) of a certain standard value into another or several types of working voltage (current) with the same frequency and different standard values. According to the supervision sampling inspection data of the third quarter of last year released by AQSIQ among the 29 kinds of dry-type transformer commodities manufactured by 29 manufacturers in 12 provinces and municipal districts across the country, 6 kinds of commodities were found to be inconsistent with the provisions of relevant specifications, with a compliance rate of 80%& ldquo; This result mostly shows the quality level of China's dry-type transformer industry at the present stage.
Therefore, in the operation prevention and regulation of relay protection dry-type transformer,TucsonPower transformer installation picture, it is necessary to find the short-circuit fault point according to the fault situation, lock the fault point, and analyze the short-circuit fault types of relay protection dry-type transformer. At the same time, if all fields are clear, disconnect the switching power supply at the fault point, the maintenance work of employees will be carried out smoothly, and the harm will not expand to a greater extent.

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.

Create brilliance.Careless maintenance and insulation damage
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, it is very easy to damage the relay protection inside and outside of dry-type transformer by lightning. If it is a serious situation and overload is not allowed in the whole process of operation.
Dry type transformer factory
For the installation of lightning rod, power failure, damage to machinery and equipment, etc.
Fair price.In relay protection dry-type transformer, the disconnection of the fault point is related to each other. In a word, if there is any problem at a certain point, it will affect the whole power circuit
Several detection methods for installing transformer
Before no-load impact closing, the pose period of overcurrent protection shall be set to zero, and the data signal circuit of steam vehicle relay shall be temporarily connected to the pull-in circuit.
Tucson.How to reduce the failure of dry-type transformer?
Due to poor sealing, generally, the sealing of box edge and machine cover is sealed with acid-base resistant rubber rod or rubber plate. If the joint is not solved well, it will lead to common faults of oil leakage.
& ldquo; YN, D11 & rdquo;, in which 11 indicates that when the working voltage phasor of the primary side line, as the minute hand, refers to the position at 12 o'clock, the phase voltage phasor of the secondary side is at 11 o'clock. That is, the phase voltage UAB of the secondary side lags 30 degrees behind the working voltage uab330 of the primary side line (or 30 degrees ahead).
