Saguarragrand315 box type transformerHow to troubleshoot common faults?

The method and whole process of taking oil sample of power transformer are as follows:When the transformer is put into operation, if the tap changer is not in time, a great & ldquo; Tweet & rdquo; The high-voltage fuse is broken when the noise is serious; If the tap changer is defective it will cause mild & ldquo; Squeak & rdquo; Corona discharge sound, once the load increases, it is likely to burn the circuit breaker of the tap changer. In case of such situation, power off immediately for maintenance.Saguarragrand,Step up process of dry-type transformer?The bearing capacity of each load is different. Generally, dry-type transformer should operate under rated capacity, while oil transformer has better load working capacity.Billdal,Power transformerThe 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.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, the rated capacity of the transformer should be selected according to the power consumption which is not suitable for too large or too small.

The vibration reduction solution of cable bridge is to modify the hard connection between bus bridge and dry-type transformer,SaguarragrandS11 dry type transformer manufacturer, and the vibration reduction solution is made at the cable bridge.The equipment can eliminate the shortcomings found in the patrol inspection, clean the porcelain waterproof casing casing, remove and replace the cracked or brittle leather pad, check and tighten the node, replenish the oil with less oil, check and replace the silica gel of the breathing mask, etc.The tail end of the high-voltage winding head and the middle tap are made of copper inserts and embedded parts, with good strength and stiffness, which is conducive to adjusting the data and has a unique and neat style.offer,In the case of using dry-type transformer, customers must master the method of wiring. If there are problems in wiring, it is easy to cause common faults in application. So, what is the wiring mode of dry-type transformer?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, 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 vibration reduction of the grounding device sheet solves the problem of modifying the fixed hard connection between the copper sheet of the grounding device and the dry-type transformer. The original oscillation of the dry-type transformer will be transmitted to the metal in the concrete by the baffle and cause low-frequency noise. Therefore, special attention shall be paid to the maintenance of solenoid coil or insulating waterproof sleeve. If there is scratch damage it shall be handled properly.Overtemperature 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.When the whole process of winding wave of oil immersed transformer is calculated by using the marking method,Saguarragrand500 kV dry type transformer, the winding of oil immersed transformer is generally divided into multiple modules, and each module is replaced by an equivalent circuit, and its power circuit includes an inductance and vertical capacitance, a capacitance to ground or capacitance between windings, They also have mutual inductors between the inductors of each module, and collect the chain Internet as the equivalent power circuit of oil immersed transformer. The precision of the conclusion can completely meet the needs of practical projects.Saguarragrand,The flange surface is uneven, the tightening bolts are loose,SaguarragrandDimensions of 1600KVA oil immersed transformer, and the installation and processing process is wrong, so that the bolts are not tightened well, and the waist rail shall be & phi; mm galvanized wire shall be wound over turns in an even number. The iron wire shall not have a connector and shall be tightened after winding. The distance between the waist rail and the energized part shall not be less than .m.
