The input and output three-phase power lines shall be connected to phase a, phase B and phase C respectively according to the color of yellow, green and red bus duct of transformer terminal board. The zero line shall be connected to the neutral zero line of transformer voltage, and the grounding wire, transformer casing and its transformer point shall be connected to each other. At ordinary times,LipayaDetailed structural drawing of dry-type transformer, the ground wire and zero wire are led out by the neutral wire of the transformer. (for example, the transformer box shall be matched with the ground wire mark of the shell and connected with each other). Check the input and output lines to ensure they are appropriate and accurate.Oil sample inspection & mdash; & mdash; the performance parameters such as compression resistance and residue shall be carried out every three years. The long-term overload or overload of the transformer can reduce the cycle time.After sampling, bind the laminated glass stopper firmly with clean paper or cloth to prevent dirt and water from contaminating the bottle stopper.Inspection environment,The iron core of power transformer is made of high-quality crystallized hot-rolled ferrite core, which is stacked at the degree fully inclined multi-step interface. The surface is covered with epoxy resin adhesive cable sheath coating which is resistant to corrosion and rust, and has sound insulation and noise reduction.What about oil immersed transformer fire?When sampling from a small and medium-sized power transformer without a discharge pipe (or oil sample suspension plate), it can be in a power transformer such as a glass test tube when it is not in operation to extract the oil sample at the bottom, or it can be replaced by changing the oil.
The plastic shells of electrical products and office supplies are equipped with grounding wires. If the insulation layer is damaged and the shell is energized, the electric flow will leak into the earth along the installed grounding wires, so as to achieve the purpose of safety, otherwise it will have an adverse impact on life safety.Quality inspection report,The clock expression is used to indicate the phase difference correlation of the working voltage of the secondary side line. The phasor of the working voltage of the primary side line is used as the minute hand, and the phasor of the phase voltage of the secondary side is used as the second hand.Transformer manufacturerOutdoor sampling shall be carried out in sunny days or dry weather with low environmental humidity. During sampling, it is necessary to resolutely prevent the invasion of dirt such as rain, snow, wind and sand.Lipaya,Method and process of taking oil sample of power transformerWhen the whole process of winding wave of oil immersed transformer is calculated by using the marking method, 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.Power transformer manufacturer
