Pinhal NovoPrice of dry-type transformerRecent market starts have increased

Manufacturing process and steps of dry-type transformerLoose core screwPinhal Novo,How to make up oil for oil immersed transformer?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, so as to play a guarantee effect. The higher the voltage, the smaller the resistance, in other words,The voltage regulating tap changer is not in place or poor(IV) the transformer on the column shall be stable and firm, 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.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.

During no-load test run, the transformer shall be connected with the working voltage from the switching power supply side and then make the working voltage impulse closing.The visual inspection method is that the staff use human eyes to observe the appearance change of the visible parts of the operating equipment to find the abnormal conditions of the equipment, such as discoloration, deformation offset, cracking, loosening, ignition smoke,Pinhal NovoDry type or oil immersed transformer for box transformer, oil leakage, broken strand disconnection, short-circuit fault marks,Pinhal NovoOil immersed transformer installation procedure, hanging of dirty things, etching and turbidity, visual inspection is one of the common methods of equipment inspection.The project cost is different. Compared with the purchase price of capacity transformer,Pinhal NovoThe dry-type transformer is good, the purchase price of dry-type transformer is much higher than that of oil immersed transformer.Meticulous workmanship,High voltage fuse of transformer breaks one phase;Different diversion methods, dry-type transformers mostly use silica gel waterproof casing, while oil transformers mostly use porcelain waterproof casing;The vibration reduction of collecting and townhouse solves the soft connection of collecting and townhouse. For the copper bar of the low-voltage bus of the equipment, the electromagnetic induced noise oscillation may be transmitted from the townhouse to the building structure. The core of noise reduction solution must be changed to copper wire connection.

The key reason for oil leakage is that there are defects in cast iron partsquery,Solenoid insulation deteriorationThe grounding resistance of, which shall not exceed % compared with the last accurate measurement result.Operation of oil immersed transformerPinhal Novo,High voltage fuse of transformer breaks one phase;In the case of dry-type transformer operation, there is more noise, and some even cause noise, which seriously endangers everyone's no problem rest time and work. At this time the dry-type transformer needs sound insulation treatment. There are many processes and key methods to deal with the noise of the common dry-type transformer. How should the noise of the dry-type transformer be solved? Or with the dry-type transformer manufacturer's network editor to simply understand it.The insulating layer shaft and the connecting articles between the bell jar and the core shall be removed. If it is a hanging bell inspection, the oil shall be pumped into the bottom of the bell jar before the bell jar can be removed.
