The technical specification of power consumption requires that the resistance of maintenance grounding wire shall be ≤ Ω, The resistor is generally more than & omega;, According to Ohm's law when the insulating layer is damaged, the current is only / of the total current flow, so as to play a guarantee effect. The higher the voltage, the smaller the resistance, in the case of high voltage. We can care about the power transformer plant and master a lot of professional knowledge.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.Madurai,Visual inspection method for transformer inspectionWiring mode of dry-type transformer:Manila,Oil leakage of heat pipe radiatorPower transformers are also used for testing, which are called test power transformers. They can be divided into inflatable, oil transformer dry test and other test power transformers. They are the basic test equipment for communication AC compression test for many consumers such as power stations, power supply bureaus and scientific research institutions. According to the specifications of the Bureau of quality supervision, It is used to carry out insulation compressive strength test under required current for various electrical products, electrical components and insulating raw materials.A specific part of dry-type transformer is the hanging core of dry-type transformer. The hanging core of dry-type transformer is a vital component. How to carry out the hanging core?

After hours of continuous trial operation with a certain load, and then the iron loss is considered and the copper loss is ignored. In fact the high-capacity transformer must be replaced by the small-capacity transformer with high utilization rate, for a certain load, the active power loss of small capacity exceeds that of large capacity The active power loss of the transformer, so it consumes electromagnetic energy.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.Discount,The power transformer is designed according to the temperature protection scheme. The embedded parts in the material layer of high (low) pressure electromagnetic coil poured with integral concrete are provided with longitudinal ventilation duct, which can be equipped with air-cooled machinery and equipment (cooling centrifugal fan). After selecting air-cooled machinery and equipment, the output capacity can be increased by %.Noise pollution control and prevention measures of dry-type transformerIf the above provisions are not met, the problem of dryness shall be solved. Generally, 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,MaduraiTransformer power transmission, 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.

Dry type transformer manufacturerPromise and keep promise,MaduraiPower transformer system,Fault judgment of power transformerAutomatic 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.Noise solution of dry-type transformerMadurai,When sampling from a small and medium-sized power transformer without a discharge pipe (or oil sample suspension plate), it can be in a power transformer such as a glass test tube when it is not in operation to extract the oil sample at the bottom, or it can be replaced by changing the oil.Different diversion methods, dry-type transformers mostly use silica gel waterproof casing, while oil transformers mostly use porcelain waterproof casing;Careless maintenance and insulation damage
