The plastic shells of electrical products and office supplies are equipped with grounding wires. If the insulation layer is damaged and the shell is energized, the electric flow will leak into the earth along the installed grounding wires, so as to achieve the purpose of safety, otherwise it will have an adverse impact on life safety.Before and after sampling, clean the periphery of the sampling port with clean or hairless linen.Beukar,First of all, although dry-type transformer has strong moisture resistance, it is generally open structure or very susceptible to moisture, especially the insulation level of dry-type transformer manufactured in China is low (lower flame retardant grade) Therefore, the dry-type transformer can obtain high stability only when the air humidity is below %. The dry-type transformer shall also be prevented from stopping operation for a long time to prevent serious damp. When the grounding resistance value is less than / V (operating voltage), it indicates that the transformer is seriously damp, and the trial operation shall be terminated.Power transformerBrvenica,The bearing capacity of each load is different. Generally, dry-type transformer should operate under rated capacity, while oil transformer has better load working capacity.Falling foreign matters and piercingOil immersed transformer operation

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 odor and other abnormal conditions. If there is any abnormality, China's first UHV transmission experimental demonstration project, China Transformer Corporation has entered a breakthrough in the development trend. The commodity voltage grade and volume rank first in the world, occupying the main technical position of the industry development trend. In addition, it has promoted the continuous improvement and perfection of the technology of low-voltage transformers.The sampling container is a colorless glass bottle with a wide mouth ground glass plug with a volume of .kg or kg. - bottles shall be collected at a time for analysis and experiment. Labels shall be attached during sampling. Pay attention to the name, source,BeukarDry type transformer and oil immersed transformer, sampling date, sampling person, weather conditions and other materials of the oil sample.install,When the new oil filled by the power transformer and the oil sample that has just been considered are used,BeukarStandard for operating temperature of oil immersed transformer, the oil sample can be used only after sufficient standing.It will also produce many faults, effectively deal with various faults 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.Oil leakage at electric welding position

The vibration reduction of the grounding device sheet solves the problem of modifying the fixed hard connection between the copper sheet of the grounding device and the dry-type transformer. The original oscillation of the dry-type transformer will be transmitted to the metal in the concrete by the baffle and cause low-frequency noise. Therefore, it must also be changed to produce flexible connection.retailer,Then clamp the branch pipe with your thumb clearly put forward the glass test tube, carry out it twice rotate and release the oil in the tube to clean the sampling tube, and then draw the oil sample.This is the example of power consumption engineering as power saving. The key reason is that the habitual calculation method ignores the copper loss.The tail end of the high-voltage winding head and the middle tap are made of copper inserts and embedded parts,BeukarDry type transformer 125kva, with good strength and stiffness, which is conducive to adjusting the data and has a unique and neat style.Beukar, there must be a strong line breaking component, so that sliding flash charge and discharge may occur at a lower current. In order to better solve this disadvantage, the appearance of the insulating parts between the winding and the iron yoke should be the same as that of the medium horizontal plane of the winding to the iron yoke insulation as far as possible, so as to reduce the electric field component intersecting with the insulating parts.What is the reason for the shutdown of power transformer?
