Avoid aging and damage of power transformer iron core insulation: aging of iron core insulation or damage of waterproof sleeve holding anchor bolt will cause large vortex of iron core, and long-term scalding of iron core will lead to insulation aging.A zero line of the power transformer is connected with the working equipment. Since the voltage formed by the server during operation will be sent to the power transformer along with the cable, the power transformer will be transported and sent to the power consuming machines and equipment. What is the zero line of the actual power transformer? Let's introduce it to us.Sligo,The iron loss of transformer includes two levels. The first is the hysteresis loss introduced by the transformer manufacturer. When the AC circuit is based on the transformer, according to the magnetic induction line of the transformer ferrite core, its orientation and size change with the change, which promotes the internal molecular structure of the ferrite core to interact with each other, releases energy, and then loses part of electromagnetic energy, which is the hysteresis loss. The other is the vortex loss when the transformer is working.When we apply oil immersed transformer, we all know that it works with the help of oil. What if the oil immersed transformer is on fire? What countermeasures should we do?Saynshand,Oil leakage of cast iron partsWhen oil samples are used, the safety and fire safety technical specifications on the spot shall be strictly implemented.A zero line of the power transformer is connected with the working equipment. Since the voltage formed by the server during operation will be sent to the power transformer along with the cable, the power transformer will be transported and sent to the power consuming machines and equipment. What is the zero line of the actual power transformer? Let's introduce it to us.

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, 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.The step-up dry-type transformer refers to the instantaneous operation of voltage. At this stage, cutting off the load current will cause arc burning between circuit breakers, tap power on and off or short circuit fault, so the dry-type transformer shall be powered off during regulation. Therefore, it is generally used as a dry-type transformer that is not very strict in voltage regulation and does not need to be adjusted frequently.The power transformer conductor refers to the connecting transmission line between each electromagnetic coil, between the electromagnetic coil and the group outlet pipe, and between the electromagnetic coil and the tap changer.consumption,The dry-type transformer is composed of two winding resistances, resulting in four wiring groups: & ldquo; y, Y & rdquo;, Y & rdquo;, & ldquo; y, D & rdquo; and & ldquo; D, D & rdquo;. In China, only & ldquo; y Y & rdquo; and & ldquo; y, D & rdquo; are selected. Because there are also two types of Y-connection with neutral line and without neutral line. If there is no neutral line, it will not be upgraded. All marks show that with neutral line, it will not be upgraded The letter N after the English letter Y indicates that the neutral line has transformer grounding wire. Yn wiring group, the minute hand points to . & ldquo; & rdquo; in the new wiring group, it is indicated by & ldquo; & rdquo.The time difference between different steps of three-phase power switch of switching power supply shall be less than ms, the closing shall be maintained by high-voltage arrester, and the neutral line of transformer shall be reliably grounded (it shall be grounded immediately).Sound 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.

Yn wiring group, the minute hand points to . & ldquo; & rdquo; in the new wiring group,SligoDo dry-type transformers have fans,SligoPrice of 200 KVA transformer, it is indicated by & ldquo; & rdquo.demandFor kVA power engineering transformer, 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.Transformer inspection earWhen using the oil sample of the power transformer in operation, it is necessary to add some oil from the oil gate valve at the lower part of the oil tank or the sampling gate valve to release about kg of waste liquid stored at the bottom to clean the oil inlet,Sligo400 KVA price of box type transformer, and then take the oil sample.Sligo,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.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, the fixed finger is at o'clock, and the phasor of the phase voltage of the secondary side is used as the second hand.For no-load impulse closing of transformer, pay attention to the following matters:
