The hanging core of dry-type transformer is a vital partThe input and output three-phase power lines shall be connected to phase a,North Santa CruzWhat is the price of 1000 KVA transformer, 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, 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.North Santa Cruz,During the operation of the transformer, the resistance value of the grounding wire shall be measured accurately every two years.If the above provisions are not met, the problem of dryness shall be solved. Generally, it is OK to operate the centrifugal fan for a period of time. Check the cleanliness of the power transformer. If too much dust is found, it must be eliminated to ensure indoor ventilation and avoid insulation penetration. In particular,North Santa CruzTransformer power transmission and ignition, pay attention to cleaning the insulators of the power transformer and the top and bottom ends of winding resistance installation. Portable centrifugal fan or dry air compression or N shall be used to clean the dust in indoor space that is not easy to reach such as ventilation duct, and there shall be no dirt.White,Oil leakage of cast iron partsWhen the power transformer operates at full load, it needs a large reactive load. This reactive load shall be provided by the power supply and distribution system. If the transformer volume is too large, it will not only increase the initial project investment, expand the proportion of full load loss, reduce power factor and increase Internet loss. Such operation is neither economic development nor scientific.Different diversion methods, dry-type transformers mostly use silica gel waterproof casing, while oil transformers mostly use porcelain waterproof casing;

When the manufacturer of the power transformer samples from the automobile oil tank, after opening the sealing cover, use the cleaned and dried rubber stopper to the oil. At the same time, clamp the branch pipe with your thumb, and loosen your thumb to make the oil enter the pipeThe cycle time of power-off cleaning and inspection shall be determined according to the surrounding environment and load conditions, dry-type transformers mostly use silica gel waterproof casing generally from half a year to once a year;Different diversion methods, while oil transformers mostly use porcelain waterproof casing;consumption,High voltage fuse of transformer breaks one phase;How to reduce the failure of dry-type transformer?Performance and main parameters of common metal composites, various welding processes and machinery and equipment, preparation treatment of thick steel plate, blanking process, production and manufacturing process and quality standards of automobile oil tank, welding leakage test and NDT technology coupling and oil storage tank cabinet, surface treatment process and quality standards, copper, Production process and quality standard of aluminum shield; Body suit iron insertion process, wire installation process, body dryness solution and dry transformer oil solution process, vacuum pump oil immersion, general installation process, leakage test and leakage detection process and quality standards. Performance parameters of key work clothes,North Santa CruzTransformer temperature in high voltage distribution room, machinery and equipment of each process flow; The natural working environment is basically regulated.

The zero line is mainly used in the working circuit. The voltage caused by the zero line is equivalent to the line resistance multiplied by the current of the working circuit. Because of the distance, the voltage caused by the zero line can not be ignored. As a countermeasure to maintain life safety, it is more and more unreliable. Ground wire (PE): it is not used as a working circuit, but only as a maintenance line. Use the affirmation of the earth & ldquo; ” Voltage. When the machine and equipment casing is electrified, the current will be quickly grounded. Even if there is a lead for the PE line, it will be grounded from the surrounding grounding body.Total quality assurance,Dry type transformer manufacturerThe transformer manufacturer will introduce the efficiency of the transformer to youSome 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.North Santa Cruz, plastic parts are selected in the middle of iron core, clamp and electromagnetic coil to keep the electromagnetic coil in a stable clamping state to reduce noise.The technical specification of power consumption requires that the resistance of maintenance grounding wire shall be ≤ Ω, The resistor is generally more than & omega;, According to Ohm's law, when the insulating layer is damaged, the current is only / of the total current flow, the smaller the resistance, in other words, in the case of high voltage. We can care about the power transformer plant and master a lot of professional knowledge.
