ShijiazhuangOil immersed transformer cooling fanInspection and maintenance

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, the packaging types are different. The transformer core and electromagnetic coil can be seen immediately for dry-type transformer, and only the shell can be seen for oil immersed transformer;Shijiazhuang,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.Avoid inadvertent damage of insulation during maintenance: when repairing the hanging core of power transformer, special attention shall be paid to the maintenance of solenoid coil or insulating waterproof sleeve. If there is scratch damage, it shall be handled properly.Rawah,In specific daily life, which dissolve and ignite, 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,ShijiazhuangWhat are the manufacturers of oil immersed transformers, endangering all normal production, manufacturing and activities. There are three reasons for fire accidents in the operation of power transformers.Power transformer manufacturer

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.The cycle time of power-off cleaning and inspection shall be determined according to the surrounding environment and load conditions, generally from half a year to once a year;Oil immersed transformerranking,Before no-load impact closing, the pose period of overcurrent protection shall be set to zero,ShijiazhuangDifference between rectifier transformer and power transformer, and the data signal circuit of steam vehicle relay shall be temporarily connected to the pull-in circuit.After the test, connect the data signal contact of the automobile relay with the alarm circuit,ShijiazhuangStructure introduction of oil immersed transformer, and adjust the overcurrent protection value.The first step of the whole wave process calculation is to calculate the basic parameters of the Internet such as inductance, capacitance and resistor. The accuracy of those basic parameters does great harm to the calculation results of the whole wave process. For the inductance calculation the good model is the solid model of infinite transformer core column, but there are many calculation methods.

How to reduce the failure of dry-type transformer?Fair priceOverload or short circuit occurs inside the power transformer. Flammable insulating raw materials are endangered by high temperature and electric isolation, which dissolve and ignite, 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.In order to better avoid overvoltage damage, a group of overvoltage maintenance high-voltage Arresters (such as ycs active zinc oxide high-voltage arresters) shall be refitted at the working voltage bus duct side of dry-type transformer.Avoid inadvertent damage of insulation during maintenance: when repairing the hanging core of power transformer, special attention shall be paid to the maintenance of solenoid coil or insulating waterproof sleeve. If there is scratch damage, it shall be handled properly.Shijiazhuang,Difference between dry-type transformer and oil immersed transformer:What is the important role of power transformerFor the leakage that has already occurred, find the leakage point first, which can not be ignored. For the position with serious leakage, 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.
