Howard160KV oil immersed transformerTalking about the technological process

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.The switching power supply lacks one phase of power;Howard,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, deformation, offset, cracking, loosening, ignition smoke, oil leakage, broken strand disconnection, short-circuit fault marks, hanging of dirty things, etching and turbidity, which can be inspected according to the visual inspection method. Therefore, visual inspection is one of the common methods of equipment inspection.It includes the performance and main uses of insulating layer materials, various insulating layer parts, component manufacturing processes and quality standards; Performance and main uses of various wires coil inductance process of various ways of electromagnetic coil, overall suit process and quality standard of electromagnetic coil; Main performance parameters of ferrite core cutting process of iron chip, core stacking process and quality standard, production process and quality standard of electromagnetic shielding.Makaz voruswali Yachin,Difference between dry-type transformer and oil immersed transformer:() the installation position of secondary commercial insurance of transformer on column and ground shall meet the following requirements: if there is an disconnector on the secondary side, it shall be installed between the disconnector and low-voltage composite insulator,HowardElectric box transformer, or the circuit breaker shall be selected as the disconnector; If there is no disconnector on the secondary side, it shall be installed on both sides of the low-voltage composite insulator,HowardWaste power transformer, and the insulated cable jumper shall be connected to the insulated cable on both sides of the circuit breaker.The conductor insulation of power transformer is the main part of internal insulation. Some conductors should pass through the middle of electromagnetic coil, or between electromagnetic coil, iron yoke clamp and automobile oil tank wall. Therefore, it is necessary to ensure that this kind of conductor has sufficient insulation compressive strength, i.e. insulation spacing.

Dry type transformer manufacturerSeveral detection methods for installing transformerWhen oil samples are used, the safety and fire safety technical specifications on the spot shall be strictly implemented.Free consultation,When oil samples are used, the safety and fire safety technical specifications on the spot shall be strictly implemented.Caused by sand holes and cracks. For crack leakage, drilling stop hole is a good way to remove in-situ stress and prevent widening.What is the wavelength of oil immersed transformer?

Power transformer plantWork courses,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, it is likely to burn the circuit breaker of the tap changer. In case of such situation,HowardPrice list of 250kVA box type transformer, power off immediately for maintenance.TransformerSound insulation treatment of main engine room the key to sound insulation treatment of dry-type transformer room is to start from three levels: window, ventilation and air exchange port and road surface and apply sound insulation window, silencing cylinder, floating concrete floor damping pad and other sound insulation and noise reduction commodities to achieve sound insulation effect.Howard,The switching power supply lacks one phase of power;(II) the height width ratio of dry-type transformer pier installed on the ground is generally .m, and a guardrail of no less than m shall be installed around it, and a warning sign shall be hung at a prominent position.Therefore, in the installation process of substation equipment, the lightning rod should be set according to the specific situation to prevent damage to the relay protection dry-type transformer caused by lightning. In addition, in the installation and use process of lightning rod, select reasonable types of lightning rod according to the operation situation to determine that they are in the same situation. In addition, during the installation of lightning rod
