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，RecifeWhat are the electronic transformers， 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.
Insulation and heat removal are different. Dry type transformers are generally insulated with epoxy resin， cooled by natural air and large capacity by centrifugal fan. Oil immersed transformers are insulated by insulating oil， insulated by insulating oil in the circulating system inside the transformer， and heat is discharged on the radiator (radiator) of the circulating system inside the transformer.
RecifeThe transformer manufacturer shall not use hand touch method to detect energized high-voltage equipment， such as transformer in operation and neutral grounding equipment of arc suppression coil. For the equipment without power supply and whose shell is reliable grounding device， pay attention to the following matters:
Peta Avoid the load operation of power transformer: if the load operation is long-term，RecifeUnit price of scb11 dry type transformer， it will lead to the scalding of solenoid coil slow aging of insulation， short circuit fault between boxes two-color short circuit fault or short circuit to ground fault and dissolution of oil.
For the leakage that has already occurred， find the leakage point first， which can not be ignored. For the position with serious leakage，RecifePower supply high frequency transformer， 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.
Falling foreign matters and piercing
In fact， 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.
Protection mode for type selection of dry-type test 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.
Supply chain quality managementUnder normal conditions， 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， so as to ensure the reliable and stable operation of machinery and equipment.
The raw materials of Fushi blue can be used for bonding， so that the overall oil leakage of the connector can be greatly controlled; If the actual operation is convenient， the metal shell can also be bonded at the same time to achieve the purpose of leakage treatment.
After the test， connect the data signal contact of the automobile relay with the alarm circuit， the pull-in contact with the opening circuit， and adjust the overcurrent protection value.
Noise pollution control and prevention measures of dry-type transformer
reformAfter no-load test run is normal for h， it can be transferred to on-load operation， and the load shall be gradually increased from %， 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.
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， so as to reduce the electric field component intersecting with the insulating parts.
