How much is the power transformerAfter no-load test run is normal for h, it can be transferred to on-load operation, and the load shall be gradually increased from %, % and % by grade.Lahosk,Power saving analysis of transformerWhat is the wiring mode of dry-type transformer?Previous Company, it can be transferred to on-load operation, and the load shall be gradually increased from %, % and % by grade.Overload or short circuit occurs inside the power transformer. Flammable insulating raw materials are endangered by high temperature and electric isolation which dissolve and ignite,LahoskPerformance of dry type transformer, resulting in a lot of steam bodies, greatly increasing the internal working pressure of the power transformer, causing the ignition of the casing, causing large-scale power failure, endangering all normal production, manufacturing and activities. There are three reasons for fire accidents in the operation of power transformers.The method and whole process of taking oil sample of power transformer are as follows:

If the oil immersed transformer is burned by the cover of the transformer, when the oil immersed transformer fails, open the lower side of the transformer and place an appropriate part. When the oil immersed transformer is on fire, the oil cannot be released to avoid the occurrence of the oil immersed transformer. At the same time use detection equipment to put out the fire immediately. In order not to expand the hazard, the fire brigade must be notified.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.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, sampling date, sampling person, weather conditions and other materials of the oil sample.Recommendation and consultation,kV and above & plusmn; No load of rated voltage; Part of the circuit breaker of the tap power switch is installed in the phenolic resin insulating paper cylinder, 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, please cut off the input switching power supply.In the case of using dry-type transformer, customers must master the method of wiring. If there are problems in wiring, it is easy to cause common faults in application. So,LahoskOil immersed transformer gear, what is the wiring mode of dry-type transformer?

Dry type transformer companyFocus on Development() the installation position of secondary commercial insurance of transformer on column and ground shall meet the following requirements: if there is an disconnector on the secondary side, it shall be installed between the disconnector and low-voltage composite insulator, or the circuit breaker shall be selected as the disconnector; If there is no disconnector on the secondary side, it shall be installed on both sides of the low-voltage composite insulator, and the insulated cable jumper shall be connected to the insulated cable on both sides of the circuit breaker.Maintenance contents of power transformerCauses of fire in power transformerLahosk,In the electric field of the winding to the yoke, 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, the actual operation of the oil immersed transformer shall be undertaken by the on-site operation and maintenance management staff. Within one week of grid connected operation, the operation and maintenance management staff shall improve the safety inspection range of the transformer, and immediately communicate and contact with the on-site project staff in case of any problems,Lahosk1000 kV Transformer, so as to ensure the reliable and stable operation of machinery and equipment.Then clamp the branch pipe with your thumb, clearly put forward the glass test tube, rotate and release the oil in the tube to clean the sampling tube, carry out it twice, and then draw the oil sample.
