PiteaDry type transformer controllerIndustry Management

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,PiteaAdvantages and disadvantages of oil immersed transformer, 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 %.() 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, 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.Pitea,The common dry-type transformer is an important electrical equipment and the voltage is constantly regulated. However, because of certain necessity, the dry-type transformer will also boost voltage, and the whole process of boosting voltage is very complex, and there are many principles.Power transformer is one of the key equipment in power station and substation. The function of power transformer is in all aspects. It can not only raise the voltage and send electromagnetic energy to the power consumption area, but also reduce the voltage to each application voltage, so as to meet the needs of power consumption. In short,PiteaPower transformer 200KVA price, voltage transformation and blood pressure reduction must be carried out by the transformer.Gizan,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?The oil in the machinery and equipment of the oil storage tank shall generally stand for more than h before sampling; it is not necessary to stand when sampling on the running power transformer.When the screw of the through core extruder holding the iron core of the transformer is loose, there are screw cap parts left on the iron core, or small metal materials fall into the transformer the transformer will send out & ldquo; Ding Ding Dang & rdquo; Or & ldquo; Call & hellip; Call & hellip& rdquo; Blowing sound and its & ldquo; Squeak, squeak & rdquo; It's like a magnet sucking a small washer, current and temperature of the transformer are all normal. Such conditions generally do not endanger all normal operation of the transformer, and can be solved until power failure.

(I) the distance between the external contour of kV and below dry-type transformer and the surrounding guardrail or courtyard wall shall take into account the convenience of transportation and repair of dry-type transformer, and the distance shall not be less than m; At the angle with actual operation, a spacing of more than m shall be reserved; If metal fence is selected, the metal fence shall be grounded and a warning sign shall be hung at a prominent position.Automatic 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.Wiring mode of dry-type transformer:Home page recommendation,The method and whole process of taking oil sample of power transformer are as follows:Oil leakage at electric welding positionThe switching power supply lacks one phase of power;

If the volume of power transformer is too small, the transformer will be overloaded for a long time and it is easy to destroy machinery and equipment. Therefore,PiteaPrice of dry-type transformer, the rated capacity of the transformer should be selected according to the power consumption, which is not suitable for too large or too small.Honest service,When checking the hook core, the insulation of the electromagnetic coil and the porcelain sleeve is usually accidentally damaged. After the shell of the pottery is broken, if you work again, turn on the photo flash when it's light, and it's short when it's heavy. Therefore, please pay attention during maintenance. It is not necessary to destroy the insulation. After maintenance, experts can inspect special tools, insulation, etc. and deliver them after they are determined to be complete and reliable.If the input of dry-type transformer is an alternating switching power supply its output voltage is directly proportional to the coil turn ratio of the output input solenoid coil. If a rechargeable battery is used, because it is DC, add a circuit in the input power supply circuit to change it into a continuously changing voltage. In that way, the alternating DC current can be obtained at the output end.Power transformer manufacturerPitea,Oil leakage of porcelain pot and laminated glass oil level gaugeIt is generally made due to unreasonable installation or ineffective sealing. Polymer composite materials can bond metal materials, porcelain, laminated glass and other materials very well, so as to achieve the pressure management of oil leakage.Dry type transformer manufacturer
