Therefore in the operation prevention and regulation of relay protection dry-type transformer, it is necessary to find the short-circuit fault point according to the fault situation,RuthRecycling power transformer, lock the fault point, and analyze the short-circuit fault types of relay protection dry-type transformer. At the same time, disconnect the switching power supply at the fault point, the maintenance work of employees will be carried out smoothly, and the harm will not expand to a greater extent.If the above provisions are not met, it is OK to operate the centrifugal fan for a period of time. Check the cleanliness of the power transformer. If too much dust is found, it must be eliminated to ensure indoor ventilation and avoid insulation penetration. In particular, pay attention to cleaning the insulators of the power transformer and the top and bottom ends of winding resistance installation. Portable centrifugal fan or dry air compression or N shall be used to clean the dust in indoor space that is not easy to reach, such as ventilation duct, and there shall be no dirt.Ruth,Power transformer is indispensable for power stations and substations, but we must pay attention to many problems in the whole process of applying power transformer.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.Villa Carlos Paz() 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.The vibration reduction solution of cable bridge is to modify the hard connection between bus bridge and dry-type transformer, and the vibration reduction solution is made at the cable bridge.When using the oil sample of the power transformer in operation, it is necessary to add some oil from the oil gate valve at the lower part of the oil tank or the sampling gate valve to release about kg of waste liquid stored at the bottom to clean the oil inlet, and then take the oil sample.

Power transformer factoryAccurately measure the resistance of each phase winding and carry out the measurement. If there is a great difference, it is a common fault of the winding. Then carry out the appearance inspection of the iron core, and then accurately measure the inter chip insulation resistor by AC voltage and galvanometer method. If the damage is not large, paint the damaged part.Generally speaking, the ignition emergency treatment method of oil immersed transformer is mainly to disconnect the oil immersed transformer,RuthMain components of box transformer, disconnect the switching power supply on each side quickly invest the reserved oil immersed transformer and start the power supply system from scratch. Stop the operation of refrigeration equipment. Key oil immersed transformer ignition. When L-type oil immersed transformer and high voltage station oil immersed transformer are ignited,RuthWhat is the price of 1000 KVA transformer, the generator set must be disassembled first.Quality Assurance,When the manufacturer of the power transformer samples from the automobile oil tank, after opening the sealing cover, use the cleaned and dried rubber stopper to the oil. At the same time, clamp the branch pipe with your thumb, and loosen your thumb to make the oil enter the pipe,After no-load test run is normal for h, it can be transferred to on-load operation, % and % by grade.When using the oil sample of the power transformer in operation, it is necessary to add some oil from the oil gate valve at the lower part of the oil tank or the sampling gate valve to release about kg of waste liquid stored at the bottom to clean the oil inlet, and then take the oil sample.

Avoid the load operation of power transformer: if the load operation is long-term, it will lead to the scalding of solenoid coil, slow aging of insulation, two-color short circuit fault or short circuit to ground fault and dissolution of oil.Product range,Power transformer factoryPower transformer is indispensable for power stations and substations, but we must pay attention to many problems in the whole process of applying power transformer.Equipped with a temperature controller, platinum thermistor (pt) is placed beside the embedded hole on the top of the low-voltage solenoid coil to test the winding resistance temperature rise of the transformer, stop the cooling centrifugal fan, set up common problem alarm, overtemperature alarm and overtemperature tripping effect, and provide reliable overvoltage protection machinery and equipment for the dry test transformer, so as to test the safety performance of the transformer operation.Ruth,When we apply oil immersed transformer, we all know that it works with the help of oil. What if the oil immersed transformer is on fire? What countermeasures should we do?When leaving the factory, the production and processing are not smooth and the sealing is poor. The common fault of oil leakage will be caused after the oil transformer is sealed for a period of time.The project cost is different. Compared with the purchase price of capacity transformer, the purchase price of dry-type transformer is much higher than that of oil immersed transformer.
