Capacity transformers generally use two types of cooling methods: forced-oriented air cooling (ODAF) and strong oil-oriented water cooling (ODWF). These two cooling methods have strong cooling effects.
If the transformer oil level is too high, we must find a way to reduce it. If the transformer oil level is too high, it will easily cause the transformer to overheat and then affect the transformer work.
The danger of transformers is very important. We must always pay attention to safety. Safety is more important than Taishan. It is necessary to use transformers reasonably, correctly, and scientifically.
Catalogue of National Standards for Power Transformers
After the transformer foundation acceptance is handed over, the surrounding construction site shall be leveled and compacted, and the unloading platform and hauling track shall be arranged. Before the main transformer is hauled to the installation point, the transformer should be checked again.
The installation of the distribution transformer should meet the user's voltage requirements, and try to avoid installing the distribution transformer in wild mountains and mountains, where it is vulnerable to lightning and away from residential areas, which is not convenient for regular maintenance by operators and management of workers. .
Manufacturers must strictly control the quality control when producing oil-immersed transformers to ensure that the three-phase voltage balance of the oil-immersed transformers produced is to minimize damage to equipment and lines. Yixing Xingyi Special Transformer Co., Ltd. is a professional electrical equipment. Manufacturers and power engineering installation service manufacturers, each piece of equipment has undergone strict factory inspection, customers can rest assured to buy.
Yixing Xingyi Special Transformer Co., Ltd. is a professional manufacturer of designing and manufacturing isolation transformers.
Isolation transformer is a relatively common transformer. The following is the introduction of isolation transformer: Isolation transformer is theoretically a safe power supply, generally used for machine repair, maintenance, protection, lightning protection and filtering.
Transformers are an indispensable and important part of the construction power supply system, so the operating conditions of the transformer will have a huge impact on the power supply system and normal construction production
Xingyi special ⎝⎛彩票注册⎞⎠: Many customers do not know what parameters need to be provided before selecting the transformer. In addition to voltage and current, the most important thing is to determine the capacity of the transformer. The following is to solve your doubts.
In general, we can quickly distinguish between American-style box transformers and European-style box transformers by their appearance. In addition, American box transformers and European box transformers have different structures and different reliability due to different structures and applications.
Test transformers and power transformers use the principle of electromagnetic induction to change the AC voltage and current of one level into another level or several different levels of voltage and current with the same frequency.
Transformers play a very important and irreplaceable role in the power system. Once the transformer stops running for some reason, it may cause the power grid in the power system to be decommissioned.
This paper discusses the necessity of using fire-resistant transformers in high-rise buildings and the requirements for transformers, introduces several related transformers, and compares the performance of these transformers in many ways.
It is mainly used to protect various inter-phase short-circuit faults that occur inside the windings of double- or three-winding transformers and their leads, and can also be used to protect single-phase inter-turn short-circuit faults of transformers.
This article describes the construction method and process of installation and commissioning of a large-scale transformer in a thermal power plant, and discusses the installation and commissioning techniques of power transformers.
First, the concept of transformer no-load test The transformer no-load test is a sine waveform and a rated voltage of a rated frequency applied to any winding (usually a low-voltage winding) of the transformer. When the other windings are open, the transformer's no-load is measured. Testing of current and no-load losses.
Transformers with the same voltage ratio, impedance voltage, and wiring group can be operated in parallel. If the voltage ratio and impedance voltage are different, they must be calculated. In the case of parallel operation, only one unit can be installed in parallel.
What need to pay attention to the transformer ratio? 1. The transformer ratio should be measured at each position of its tap changer.
