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.Noise solution of dry-type transformerAlvarden,Several detection methods for installing transformerkV and above & plusmn; No load of rated voltage; Part of the circuit breaker of the tap power switch is installed in the phenolic resin insulating paper cylinder and the insulating paper cylinder is installed on the wooden frame. The actual operation rocker is connected with the dynamic circuit breaker of the tap power switch according to the wooden insulating rod. The on load tap off power switch is insulated from the ground by the insulating paper cylinder of the power switch itself and the insulating limit.Cheria,Due to poor sealing, generally, the transformer will be overloaded for a long time and it is easy to destroy machinery and equipment. Therefore it will lead to common faults of oil leakage.If the volume of power transformer is too small, 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 sampling container is a colorless glass bottle with a wide mouth ground glass plug with a volume of .kg or kg. - bottles shall be collected at a time for analysis and experiment. Labels shall be attached during sampling. Pay attention to the name, source,AlvardenOil immersed transformer cooling fan, sampling date, sampling person, weather conditions and other materials of the oil sample.

What is the reason for the shutdown of power transformer?It should be said that after the development trend of these years, the overall level of China's transformer industry at this stage is basically international, and the quality level is no different from that of overseas goods& rdquo; The person in charge of the transformer Federation of China Household Appliance Industry Association said.Some are tied with plastic tape, and some immediately press the two edges together, because the socket can not be pressed firmly during installation, and there is still oil leakage without sealing effect.Good quality,The oil in the machinery and equipment of the oil storage tank shall generally stand for more than h before sampling; it is not necessary to stand when sampling on the running power transformer.& ldquo; YN, D & rdquo;, in which indicates that when the working voltage phasor of the primary side line,AlvardenTransformer power transmission, as the minute hand, refers to the position at o'clock, the phase voltage phasor of the secondary side is at o'clock. That is the phase voltage UAB of the secondary side lags degrees behind the working voltage uab of the primary side line (or degrees ahead).For the leakage that has already occurred, find the leakage point first, which can not be ignored. For the position with serious leakage, shovel or sharp punch can be selected. The leakage point can be riveted with special tools for metal materials. After manipulating the leakage, the treatment surface shall be cleaned and tidy. Polymer composite materials are mostly selected for dry consolidation. After dry consolidation,AlvardenRecovery price of dry-type transformer, the goal of long-term treatment of leakage can be achieved.

High voltage fuse of transformer breaks one phase;production,What is the wiring mode of dry-type transformer?When the output power P of the transformer is equivalent to the input power P, the efficiency & ETA; Equivalent, the transformer will not cause loss. But in fact, there is no such transformer. The electromagnetic energy of transformer always causes loss. The key of this kind of loss is copper loss and iron loss. Copper loss refers to the loss caused by the number of turns of transformer coil. When the current has a fever according to the number of turns of the coil, it is called copper loss.Turn off the gate valve (butterfly valve) of the left and right tablet computers of the heat pipe radiator to isolate the oil in the heat pipe radiator from the oil in the tank, so as to reduce the working pressure and leakage. After the leakage location is determined, and then Fushi blue raw materials shall be selected for sealing treatment.Alvarden,Loose core screwPower transformer is one of the key equipment in power station and substation. The function of power transformer is in all aspects. It can not only raise the voltage and send electromagnetic energy to the power consumption area, but also reduce the voltage to each application voltage, so as to meet the needs of power consumption. In short, voltage transformation and blood pressure reduction must be carried out by the transformer.Oil immersed transformer
