Premium transformer core cutting machine supplier factory: What is the protection scope of gas protection? In oil-immersed transformers, the scope of gas protection inside the transformer mainly includes the gas content in the transformer oil. Normally, the oil in an oil-immersed transformer is used for insulation and cooling, but when the transformer fails or ages inside, gases such as gas and hydrogen will be generated, which will lead to an increase in the gas content in the oil. If the gas content in the oil is too high, it will cause the insulation performance of the oil to decrease, which will cause the transformer to malfunction or even explode. Therefore, in order to protect the safe operation of the transformer, it is necessary to monitor and control the gas content in the transformer oil. Generally speaking, the gas relay is a commonly used gas monitoring device in oil. The gas relay can monitor the change of the gas content in the oil, and send out an alarm signal when the gas concentration exceeds a certain threshold, so as to carry out repair and maintenance in time. In short, the gas protection range inside the transformer mainly refers to the gas content in the transformer oil, which needs to be monitored and controlled by devices such as gas relays to protect the safe operation of the transformer.

Why does the current source inverter need a larger transformer capacity? Current source inverter is a common type of inverter. Its control method adopts current loop control, which has the advantages of high precision and strong adaptability, and is widely used in industrial production. Due to the working characteristics of the current source inverter, a large transformer capacity is required for the following reasons: The current source inverter adopts the intermediate inductance: the current source inverter adopts the intermediate inductor, which can realize the phase difference between the output voltage and the current, so as to realize the frequency conversion control. However, since the intermediate inductor needs to withstand large current and voltage, it is necessary to select a transformer with a larger capacity to ensure the normal operation of the inductor.
Power Quality and Distribution Transformers – The efficiency of distribution transformer substations is significantly affected by power quality. These transformers, which are critical components of the electrical distribution system, convert high-voltage electricity into lower voltage levels suitable for end-use applications. The performance and efficiency of these transformers largely depend on the quality of power they receive. Poor power quality, characterized by voltage sags, swells, harmonics, and flicker, can lead to increased losses in power distribution transformers. These losses can be categorized into two types: core losses and copper losses. Core losses occur due to variations in the magnetic field within the transformer’s core, while copper losses occur due to the resistance of the transformer’s windings. Both these losses are exacerbated under conditions of poor power quality, leading to decreased efficiency of the transformer.

The cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). When air cooled naturally, the transformer can run continuously for a long time under rated capacity. When forced air cooling, transformer output capacity can be increased by 50%. Suitable for intermittent overload operation, or emergency overload operation; Because the load loss and impedance voltage increase greatly during overload, it is in non-economic operation state, so it should not be in continuous overload operation for a long time.Welcome to inquiry price for dry type substation transformer.
A transformer coil winding machine is an intricate piece of machinery with an essential role in the manufacturing of transformers, combining modern technology and meticulousness to create high-quality products efficiently. The process starts with the feeding of copper wire into the machine, which passes through a line-up of calibrations guides and tensioners designed to secure alignment and prevent damage. An automated system then causes rotation, gradually looping copper wire around the transformer coil. A computerized system oversees variables such as speed, pitch control, layer count and insulation thickness for consistent turns. Moreover, for distinct transformer models or designs, these machines can be fitted with extra features such as automatic lead cutting and tapping mechanisms for increased versatility and productivity.

Laser welding machine is an efficient and precise welding method using high energy density laser beam as a heat source. Laser welding is one of the important applications of laser material processing technology. It mainly used for welding thin wall material and low speed in the 1970 s. The welding process is thermal conduction, i.e. the laser radiation heating surface, the surface heat to the internal diffusion through heat conduction, by controlling the width of laser pulse, energy, peak power and repeating frequency, parameters such as melting of components, to form specific molten pool. Because of its unique advantages, it has been successfully used in precision welding of micro and small parts.As one of the best laser welding machine manufacturers in China, Canwin specialized in handheld laser welding machine and wholesale fiber laser welding machine making for over 20 years.
Digital measurement – Digital measurement of transformers or other components can be conducted, and the measurement results can be called and collected from the process layer and station control layer through digital networks, thus monitoring transformers and other equipment.Status visualization – The operation status of transformers can be visualized and observed in the power grid.Smart grid or other related systems can express the status information of transformer self-detection or information interaction.
Impedance voltage (%): Short-circuit the secondary winding of the transformer and slowly increase the voltage on the primary winding. When the short-circuit current of the secondary winding equals the rated value, the voltage applied on the primary side is the impedance voltage. It is usually expressed as a percentage of the rated voltage. Phase number and frequency: Three-phase is represented by S, and single-phase is represented by D. The frequency f of China’s national standard is 50Hz.There are countries abroad with 60Hz (such as the United States).I. Temperature rise and cooling: The difference between the temperature of the transformer winding or upper oil layer and the temperature of the surrounding environment is called the temperature rise of the winding or upper oil layer. The limit value of the temperature rise of the oil-immersed transformer winding is 65K, and the temperature rise of the oil surface is 55K.There are also various cooling methods: oil-immersed self-cooling, forced air cooling, water cooling, tube type, sheet type, etc.
