Single-phase rectifier transformer
Single-phase rectifier transformer

ZSG three-phase dry-type rectifier transformer is an important part of rectifier equipment (belonging to dry-type transformer), and it forms a rectifier circuit system with various rectifier devices. In order to convert AC power to DC power, the rectifier transformer first converts the voltage of the AC power grid into a voltage of a certain size and number of phases, and then passes through a rectifier (rectifier) and outputs it to the DC drag device. BKZ, ZSG series rectifier transformer is a combination of BK, transformer or SG transformer and rectifier components. The transformer is suitable for the primary side 220V or 380V AC 50HZ power supply. The secondary side rectifies and outputs DC through the rectifier element, which changes the AC to DC. The rectifier transformer is connected to the AC power grid on the primary side and the silicon rectifier on the secondary side, also called the valve side. The output waveform is not a sine wave. According to the requirements of the rectifier, the valve side connection methods are different. Full-wave rectification is made up of 2 diodes. Because the current directions of the two sets of the same power supply are opposite, during a change period of the waveform of the alternating current, one diode is turned on and rectified during the positive half cycle, and the other diode is turned off, and turned off when the negative half cycle is turned on. Cut-off, that is, the full-wave rectified DC power is connected to each other. Common rectifier circuits are single-phase half-wave, single-phase full-wave, three-phase half-wave, three-phase full-wave (Y or △) bridge type, three-phase tortuous type (Zo shape) , Six-phase Y-shaped (midpoint wiring), six-phase fork (also zigzag), six-phase Y-shaped parallel bridge type (with balanced reactor), six-phase △ Y-shaped series bridge type, twelve-phase four-zigzag shape With balanced reactor, six-phase Y-shaped or △ form, six-phase (twelve, twenty-four-phase) double reverse star with balanced reactor, or multiple sets of parallel bridge type, double reverse star circuit. The DC current can reach 25KA, and the DC voltage ranges from tens of volts to hundreds of volts. The valve side often uses the same-phase anti-parallel method to output the wires.

Three-phase rectifier transformer
Three-phase rectifier transformer

ZSG three-phase dry-type rectifier transformer is an important part of rectifier equipment (belonging to dry-type transformer), and it forms a rectifier circuit system with various rectifier devices. In order to convert AC power to DC power, the rectifier transformer first converts the voltage of the AC power grid into a voltage of a certain size and number of phases, and then passes through a rectifier (rectifier) and outputs it to the DC drag device. BKZ, ZSG series rectifier transformer is a combination of BK, transformer or SG transformer and rectifier components. The transformer is suitable for the primary side 220V or 380V AC 50HZ power supply. The secondary side rectifies and outputs DC through the rectifier element, which changes the AC to DC. The rectifier transformer is connected to the AC power grid on the primary side and the silicon rectifier on the secondary side, also called the valve side. The output waveform is not a sine wave. According to the requirements of the rectifier, the valve side connection methods are different. Full-wave rectification is made up of 2 diodes. Because the current directions of the two sets of the same power supply are opposite, during a change period of the waveform of the alternating current, one diode is turned on and rectified during the positive half cycle, and the other diode is turned off, and turned off when the negative half cycle is turned on. Cut-off, that is, the full-wave rectified DC power is connected to each other. Common rectifier circuits are single-phase half-wave, single-phase full-wave, three-phase half-wave, three-phase full-wave (Y or △) bridge type, three-phase tortuous type (Zo shape) , Six-phase Y-shaped (midpoint wiring), six-phase fork (also zigzag), six-phase Y-shaped parallel bridge type (with balanced reactor), six-phase △ Y-shaped series bridge type, twelve-phase four-zigzag shape With balanced reactor, six-phase Y-shaped or △ form, six-phase (twelve, twenty-four-phase) double reverse star with balanced reactor, or multiple sets of parallel bridge type, double reverse star circuit.

SCB13 dry-type transformer
SCB13 dry-type transformer

The characteristics of SCB13 dry-type power transformer products are low loss: The no-load loss of the product is more than 20% lower than that of SCB11 type products, which has excellent energy saving effect, economic operation and maintenance-free. Low noise: The noise level of the product is lower than the current professional standard JB / T10088-1999 "6-220KV transformer sound level" by more than 10-15 decibels. Low partial discharge: The resin mixing material adopts two foreign mixing methods and vacuum film degassing technology to make the mixture stir evenly and eliminate air bubbles in the mixture. The product has very low partial discharge and can be controlled below 5PC. The high and low voltage coils are cast under vacuum and pressure, so that the resin insulation has both full encapsulation and inter-turn leaching. The casting body has a dense solidified structure, which is resistant, explosion-proof, and does not pollute the environment. Insulation materials such as glass fiber wound coils have self-extinguishing properties, and no arc will be generated due to short circuit. The resin will not generate toxic and harmful gases under high heat. High mechanical strength: the resin with filler makes the difference in expansion coefficient in the casting body small, the curing shrinkage rate is small, the internal stress is small, and the hardness of the cured product is high. The prefabricated reinforced material has a dense structure like reinforced concrete, so the mechanical strength is greater than that of pure epoxy resin, and it can withstand sudden short-circuit electric force without damage.

Oil-immersed power transformer
Oil-immersed power transformer

> Operating conditions of oil-immersed transformers are not higher than 1000m indoor or outdoor. ** Ambient air temperature + 40 ° C ** Daily average temperature + 30 ° C ** Annual average temperature + 20 ° C ** Air temperature -25 ° C Available on request Transformers operating under special conditions of use. > Model description of oil-immersed transformers GBS11 power transformer coils are wound with high-quality oxygen-free copper wires, and the heat dissipation adopts a new oil channel structure. The design is reasonable, and the insulation process is optimized to improve mechanical strength and short-circuit resistance. The core is made of high-quality cold-rolled silicon steel sheet, with stepped three-level joints, and the surface is coated with cured paint, which reduces the loss and noise. Beautiful appearance and reliable operation. The S11 series 35KV power transformer meets the national GB1094-1996 "Power Transformer" GB / T6451-1999 "Three-phase oil-immersed power transformer technical parameters and requirements" standards, and is widely used in substations (stations) and urban and rural power grids. > Transformer product features: 1. The series of power transformer cores are made of silicon steel sheet and rolled without seams and non-gradations, which are close to pure circular cross sections. The iron yoke and the iron core are connected with rounded corners, and the iron core is closed. 2. The high and low voltage coils are directly wound on the iron core. The two coils have good concentricity and good short-circuit resistance. 3.Due to the special core structure and annealing of high-quality cold-rolled silicon steel sheets with crystalline orientation, the S11-MR transformer has a 30% reduction in no-load loss and a 70% reduction in no-load current compared with the same capacity GBS9 type. The noise dropped about 8 decibels. 4. The power transformer cancels the oil storage tank. A corrugated oil tank is used. The oil volume change caused by temperature is adjusted by the elasticity of the corrugated sheet to isolate the transformer oil from the air and prolong its use. 5. The power transformer adopts a corrugated fuel tank with a small temperature rise and a small footprint, and its appearance is beautiful. 6. The core processing is all mechanized, which reduces labor intensity and improves product quality and quality. Specifications and sizes and packaging are processed according to customer requirements.
