`IBRICharacterWhen the transformer is out of phase, if the second phase is blocked, there is still no sound when the second phase is sent, and there is sound when the third phase is sent; If the third phase is blocked, the sound will not change, as in the case of the second phase. There are three reasons for phase deficiency:
Therefore, in the operation prevention and regulation of relay protection dry-type transformer, it is necessary to find the short-circuit fault point according to the fault situation, lock the fault point, if all fields are clear, disconnect the switching power supply at the fault point, the maintenance work of employees will be carried out smoothly,Monte Cristo San FernandoComprehensive protection of power transformer, and the harm will not expand to a greater extent.
Monte Cristo San Fernando.Dry type transformer, a static electrical equipment, 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.

.Plug in the power with full load first, observe and detect that the input and output voltage meets the regulations. At the same time, check whether the equipment has abnormal sound, ignition,Monte Cristo San FernandoDry type transformer applications, odor and other abnormal conditions. If there is any abnormality, resulting in short circuit between coils oil leakage is often caused. This is due to the supporting force on the surface of the pipe and the working pressure on the inner cavity when stamping the heat discharge pipe.
The long-term overload of power transformer will slowly cause the scalding and insulation aging of solenoid coil, 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.
Brief introduction of zero line of power transformer
At rated power,Monte Cristo San FernandoScb13 dry type transformer with secondary energy efficiency, the ratio of output power to input power of transformer is called the efficiency of transformer, i.e. & ETA; Is the efficiency of the transformer; P1 is the input power and P2 is the output power.
Power transformer factory
Word of mouth recommendation.The manufacturing process of dry-type transformer is very process, and must be technically as a certain pillar. Only in that way, the performance of dry-type transformer will be more stable. What are the common manufacturing processes and steps of dry-type transformer?
For the leakage that has already occurred, find the leakage point first, which can not be ignored. For the position with serious leakage shovel or sharp punch can be selected. The leakage point can be riveted with special tools for metal materials. After manipulating the leakage, the treatment surface shall be cleaned and tidy. Polymer composite materials are mostly selected for dry consolidation. After dry consolidation, the goal of long-term treatment of leakage can be achieved.
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.

Monte Cristo San Fernando.From the appearance, the packaging types are different. The transformer core and electromagnetic coil can be seen immediately for dry-type transformer, and only the shell can be seen for oil immersed transformer;
In specific daily life, oil immersed transformers are released outward in the form of waves. This kind of wave is like a tide. It is also a kind of kinetic energy. In fact, the wave height of oil immersed transformer also shows the size of kinetic energy. Generally, computer automatic system is used to control the wavelength and frequency of electromagnetic wave. The longer the light wavelength is, the greater the output power is. On the contrary, it is very small.
