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, and a guardrail of no less than m shall be installed around it, and a warning sign shall be hung at a prominent position.Lahti ,The insulation of the through core anchor bolt clamping the iron core is damaged,Lahti Dry type power transformer brand, resulting in a short circuit fault between the silicon steel sheet of the iron core and the through core anchor bolt;Difference between dry-type transformer and oil immersed transformer:Leo,Dry type transformer oscillation is solved by applying vibration damping platform to dry-type transformer and carrying out low-frequency vibration reduction management which can control the oscillation below .%, and then reduce the building structure noise transmitted by dry-type transformer oscillation.Power transformer is an idealized supporting facility transformer for medium cabinet and high-voltage cabinet at the present stage, and can be equipped with safety protective casing according to different waterproof grades. It is applicable to key or unique natural environment sites such as multi-storey buildings, commerce, airports, tunnel construction, chemical enterprises and factories.The tail end of the high-voltage winding head and the middle tap are made of copper inserts and embedded parts, which is conducive to adjusting the data and has a unique and neat style.

When the power transformer operates at full load, it needs a large reactive load. This reactive load shall be provided by the power supply and distribution system. If the transformer volume is too large, it will not only increase the initial project investment, but also make the transformer operate at full load or load for a long time, expand the proportion of full load loss, reduce power factor and increase Internet loss. Such operation is neither economic development nor scientific.Visual inspection method for transformer inspectionFault judgment of power transformerdevice management,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.Fault judgment of power transformerOil leakage of cast iron parts

The power transformer is composed of two or more electromagnetic coils wound around the same transformer core. The winding resistance is connected according to the alternating electromagnetic field and works according to the basic principle of magnetic effect of current. The installation position of power transformer shall be considered to be conducive to operation, maintenance and transportation,Lahti Prefabricated box type transformer substation, and a reliable area shall be selected at the same time. The rated capacity of the transformer must be effectively used when applying the transformer.Variable cost,The power transformer is composed of two or more electromagnetic coils wound around the same transformer core. The winding resistance is connected according to the alternating electromagnetic field and works according to the basic principle of magnetic effect of current. The installation position of power transformer shall be considered to be conducive to operation, maintenance and transportation, and a reliable area shall be selected at the same time. The rated capacity of the transformer must be effectively used when applying the transformer.During the operation of the transformer,Lahti Box type transformer door, the resistance value of the grounding wire shall be measured accurately every two years.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, plastic parts are selected in the middle of iron coreFor kVA power engineering transformer, clamp and electromagnetic coil to keep the electromagnetic coil in a stable clamping state to reduce noise.The iron core of power transformer is made of high-quality crystallized hot-rolled ferrite core, which is stacked at the degree fully inclined multi-step interface. The surface is covered with epoxy resin adhesive cable sheath coating, which is resistant to corrosion and rust, and has sound insulation and noise reduction.Power transformer
