The input and output three-phase power lines shall be connected to phase a, phase B and phase C respectively according to the color of yellow, green and red bus duct of transformer terminal board. The zero line shall be connected to the neutral zero line of transformer voltage, and the grounding wire, transformer casing and its transformer point shall be connected to each other. At ordinary times, the ground wire and zero wire are led out by the neutral wire of the transformer. (for example, the transformer box shall be matched with the ground wire mark of the shell and connected with each other). Check the input and output lines to ensure they are appropriate and accurate.What is the wiring mode of dry-type transformer?Mahachi kara,Transformer inspection earFalling foreign matters and piercingIlkutsk,Mahachi karaReactance transformer,Oil leakage at looper flangeOn load commissioning:In order to better reduce the probability of short-circuit fault of relay protection dry-type transformer, prevention and key are & ldquo; Prevention and Manipulation & rdquo; Is dominant.

A specific part of dry-type transformer is the hanging core of dry-type transformer. The hanging core of dry-type transformer is a vital component. How to carry out the hanging core?Automatic system of centrifugal fan: measure the temperature data signal according to the PT thermistor temperature measuring resistor of the embedded parts at the hot part of the bottom pressure winding. The transformer load expands and the operating temperature increases. When the winding temperature reaches ℃, the system software automatically starts the centrifugal fan for refrigeration; When the winding temperature is as low as ℃, the system software will automatically terminate the centrifugal fan.On load commissioning:Recommendation and consultation,Mahachi karaTransmission transformer,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?Caused by sand holes and cracks. For crack leakage, drilling stop hole is a good way to remove in-situ stress and prevent widening.Manufacturing process and steps of dry-type transformer

Therefore, in the installation process of substation equipment, the lightning rod should be set according to the specific situation to prevent damage to the relay protection dry-type transformer caused by lightning. In addition, in the installation and use process of lightning rod, select reasonable types of lightning rod according to the operation situation to determine that they are in the same situation. In addition, during the installation of lightning rod, please connect all routes as far as possible to prevent other faults.Honesty is the foundation,Noise dispersion of dry-type transformerPower saving analysis of transformers has always been based on whether the utilization rate of transformer capacity is less than a certain standard value. Whether transformers are environmental protection and energy saving specifications. In fact, sometimes such specifications are not saving electromagnetic energy, ventilation and air exchange port and road surface,Mahachi karaPower transformer recovery, and apply sound insulation window, silencing cylinder floating concrete floor damping pad and other sound insulation and noise reduction commodities to achieve sound insulation effect.Mahachi kara,Difference between dry-type transformer and oil immersed transformer:(IV) the transformer on the column shall be stable and firm, 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:
