For oil transformer oil replenishment, unused transformer oil conforming to the new standard should be selected first. In addition, the oil with the same basic, same brand and same additive type is expected to have a stronger effect. The characteristics of the oil should not be lower than that of the oil in mechanical equipment. When the new remaining oil is less than %, there is generally no problem. However, if there is more new remaining oil,power transformer price 1000kva oil shall be added before oil type Chromatographic analysis and pressure test shall be carried out to establish that there is no oil stain,St TrudenOil immersed transformer foundationMarket chaos is worrying and the acid value and dielectric loss shall not exceed the oil in the machinery and equipment.

0Automatic 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.

cBrasiaThe vibration reduction solution of cable bridge is to modify the hard connection between bus bridge and dry-type transformer, and the vibration reduction solution is made at the cable bridge.

At that time, only a few companies in China could produce kV high-voltage transformers, and the market share of high-voltage transformers was basically monopolized by overseas leaders.

UuTransformer is a kind of power engineering equipment that converts 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 in the whole process of electromagnetic energy transmission. 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 visual inspection method is that the staff use human eyes to observe the appearance change of the visible parts of the operating equipment to find out the abnormal conditions of the equipment,power transformer price 1000kva such as discoloration, deformation, loosening, ignition and smoke, oil leakage and oil leakage, broken strand disconnection, short-circuit fault marks, hanging of dirty things, etching and turbidity, etc. can be checked according to the visual inspection method. Therefore,power transformer price 1000kva visual inspection is one of the common methods of equipment inspection.

Therefore,Power transformer price: 1000KVA, 33kV, 25kV, power transformer, oil immersed transformer, dry-type transformer factory visual inspection is one of the common methods of equipment inspection.

yNaturally, if the oil immersed transformer catches fire, please dont panic. I firmly believe that the damage will be reduced to a lower level as long as the above methods are effectively rectified. Above is the general process and process that should be paid special attention to in the whole ignition process of the oil immersed transformer. When the oil immersed transformer catches fire, please be rational to make the oil immersed transformer safer and more efficient.

KMarket trendIt should be said that after the development trend of these years, the overall level of Chinas transformer industry at this stage is basically international and the quality level is no different from that of overseas goods& rdquo; The person in charge of the transformer Federation of China Household Appliance Industry Association said.

bKThe proper selection of Anhui dry-type transformer has a key effect on improving the safety and smooth operation of power system software. In the above original text, we have already mastered the structure and characteristics of dry-type transformer. In this part, we will describe how to select dry-type transformer according to the load characteristics and application environment of dry-type transformer.

It should be said that after the development trend of these years, the overall level of Chinas transformer industry at this stage is basically international, voltage transformer, automobile relay, AC contactor, etc.) operates normally. According to the AC current, the winding transformer core will send out a symmetrical rhythm and a certain tone & ldquo; Buzz, buzz & rdquo; Sound. The operation staff of the transformer manufacturer should understand and grasp the characteristics of the noise. When the equipment has common faults, there will be noise and even & ldquo; Crackle & rdquo; The charging and discharging sound can distinguish the generation and characteristics of common equipment faults according to the music law and sound transformation when everything is normal and abnormal.

YIn 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 iron loss of transformer includes two levels. The first is the hysteresis loss introduced by the transformer manufacturer. When the AC circuit is based on the transformer, according to the magnetic induction line of the transformer ferrite core, its orientation and size change, which promotes the internal molecular structure of the ferrite core to rub against each other, releases energy, and then loses part of electromagnetic energy which is the hysteresis loss. The other is the vortex loss when the transformer is working.

bCOvertemperature alarm and trip: collect winding or iron core temperature data signals according to the temperature measurement resistor of PTC discrete system thermistor embedded in the bottom voltage winding. When the transformer winding temperature rises again, if it reaches ℃, the system software outputs the overtemperature alarm system; If the temperature rises to ℃ again and the transformer can no longer operate, the overtemperature trip data signal must be transported to the secondary maintenance circuit, and the transformer shall be tripped quickly.

First of all, although dry-type transformer has strong moisture resistance, it is generally open structure or very susceptible to moisture, especially the insulation level of dry-type transformer manufactured in China is low (lower flame retardant grade) Therefore, the dry-type transformer can obtain high stability only when the air humidity is below %. The dry-type transformer shall also be prevented from stopping operation for a long time to prevent serious damp. When the grounding resistance value is less than / V (operating voltage), it indicates that the transformer is seriously damp, and the trial operation shall be terminated.
