ParanaOil immersed power transformer manufacturer,

Before application, soapy water or other organic solvents (such as trisodium phosphate) except oil stains, and then washed with tap water until it is not alkaline, and the water can be evenly distributed from the bottle, and then cleaned with purified water for many times. The cleaned sampling container shall be dried in a ℃ drying oven. After refrigeration, the bottle cap shall be tightly closed and cannot be opened before application.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.Parana,TransformerThe 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.Salwa,Oil leakage of cast iron parts& ldquo; of wiring transformer; Enter & rdquo; And & ldquo; Output & rdquo; Use a megger to test the grounding resistance between the terminal and the ground wire. When accurately measured by V megger, the resistance value exceeds m ohm bus.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?

Oil leakage at electric welding positionA kind of power engineering equipment that converts the working voltage and current according to the basic law of magnetic effect of current. In the whole process of power transmission and transformation of power engineering, it is necessary to carry out voltage transformation and blood pressure reduction according to the transformer to reduce the loss of electromagnetic energy in the whole process. Therefore, the power consumption of the processing plant is all connected with kV switching power supply, which is converted into bottom voltage electromagnetic energy through transformer.The long-term overload of power transformer will slowly cause the scalding and insulation aging of solenoid coil, resulting in short circuit between coils, two-color short circuit or short circuit on the ground, resulting in the ignition of power transformer. Therefore, the insulation compressive strength of power transformer shall be tested before installation and operation, and overload is not allowed in the whole process of operation.Quotation sheet,ParanaHow much is a 400 KVA box transformer,How much is the power transformerPower transformer plantIn order to better reduce the probability of short-circuit fault of relay protection dry-type transformer, prevention and key are & ldquo; Prevention and Manipulation & rdquo; Is dominant.

The long-term overload of power transformer will slowly cause the scalding and insulation aging of solenoid coil, resulting in short circuit between coils, two-color short circuit or short circuit on the ground, resulting in the ignition of power transformer. Therefore, the insulation compressive strength of power transformer shall be tested before installation and operation, and overload is not allowed in the whole process of operation.superior quality,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,ParanaModel and specification of power transformer, the good model is the solid model of infinite transformer core column, but there are many calculation methods.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;Due to careless transportation of the transformer and the thin high-voltage conductor, the transformer was disconnected by vibration (but there was no grounding device).ParanaAvoid aging and damage of power transformer iron core insulation: aging of iron core insulation or damage of waterproof sleeve holding anchor bolt will cause large vortex of iron core
