Sound insulation treatment of main engine room the key to sound insulation treatment of dry-type transformer room is to start from three levels: window, ventilation and air exchange port and road surface, silencing cylinder floating concrete floor damping pad and other sound insulation and noise reduction commodities to achieve sound insulation effect.After the test, the pull-in contact with the opening circuit, and adjust the overcurrent protection value.St. patten,In order to promote the use of energy-saving transformers, the Ministry of finance, the Ministry of industry and information technology and the national development and Reform Commission jointly promulgated the detailed rules for the implementation of energy-saving distribution transformers of energy-saving products benefiting the people project as early as , providing subsidies of - yuan / KVA for energy-saving transformers.Solenoid insulation deteriorationKaterini,What is the wavelength of oil immersed transformer?The vibration reduction of collecting and townhouse solves the soft connection of collecting and townhouse. For the copper bar of the low-voltage bus of the equipment, the electromagnetic induced noise oscillation may be transmitted from the townhouse to the building structure. The core of noise reduction solution must be changed to copper wire connection.Plug in the power with full load first, observe and detect that the input and output voltage meets the regulations. At the same time,St. pattenPrice of 50 KVA box type transformer, check whether the equipment has abnormal sound, ignition, odor and other abnormal conditions. If there is any abnormality, please cut off the input switching power supply.

When 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:For oil transformer oil replenishment, unused transformer oil conforming to the new standard should be selected first. In addition, the oil with the same basic, same brand and same additive type is expected to have a stronger effect. The characteristics of the oil should not be lower than that of the oil in mechanical equipment. When the new remaining oil is less than %, there is generally no problem. However, if there is more new remaining oil, oil shall be added before oil type Chromatographic analysis and pressure test shall be carried out to establish that there is no oil stain, and the acid value and dielectric loss shall not exceed the oil in the machinery and equipment.In fact, ground wire is not only a kind of grounding protection. The following describes in detail that ground wire is the general name of grounding system. Ground wire is divided into protective grounding and safety factor grounding device. Among them, safety factor grounding device can be divided into grounding protection, anti electric shock grounding device and anti electromagnetic wave radiation grounding device. Protective grounding is to use it for loop to make the facilities achieve the grounding wire specified by the function.Bidding,Before and after sampling, clean the periphery of the sampling port with clean or hairless linen.The insulation distance between the winding and the iron yoke of power transformer is much larger than that between the windings, most of the cables are in phase with the insulating cylinder (plate) in the middle of the winding, that is, the disconnection component of the electric field is small.Noise solution of dry-type transformer

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.For more, please check,The flange surface is uneven, the tightening bolts are loose, and the installation and processing process is wrong, so that the bolts are not tightened well,St. pattenOutline dimensions of 2500kVA dry type transformer, resulting in oil leakage.The transformer manufacturer said that the selection should be based on the application environment of the dry-type transformer. For the extremely extreme environment, the dry-type transformer should be poured with epoxy resin glue. Because this kind of environment does not need to heat the dry-type transformer, it can operate immediately. However, for the general application environment, the class H dry-type transformer can be used.What is the wavelength of oil immersed transformer?St. patten,St. pattenRecovery of transformer cabinet,How to reduce the failure of dry-type transformer?Turn off the gate valve (butterfly valve) of the left and right tablet computers of the heat pipe radiator to isolate the oil in the heat pipe radiator from the oil in the tank, so as to reduce the working pressure and leakage. After the leakage location is determined, appropriate surface treatment shall be carried out, and then Fushi blue raw materials shall be selected for sealing treatment.The representative mode of connection group of dry-type transformer is: English capital letters indicate the wiring on the primary side (or primary side), and English letters indicate the wiring on the secondary side (or secondary side). Y (or y) is star wiring and D (or D) is triangular wiring.
