SanzakatPower transformer test guideThe market rebounded after falling

Dry type transformer factoryCaused by sand holes and cracks. For crack leakage, drilling stop hole is a good way to remove in-situ stress and prevent widening.Sanzakat,The grounding resistance of, high voltage and bottom voltage shall not be less than % (m & omega;) of the original value. The difference between the three-phase mean value of winding resistance measurement at the same temperature shall not exceed %,SanzakatHow much is a 100 KVA box transformer, which shall not exceed % compared with the last accurate measurement result.If the power transformer stops running for more than h (if the allowable time should be reduced when the ambient humidity is & amp; gt; %), it should be insulated before putting into use, and accurately measured with a V grounding megger. The insulation resistance from the primary side to the secondary side and the ground should be ^ mfl the insulation resistance from the secondary side to the ground should be ^ mh,For the installation of lightning rod, it is very easy to damage the relay protection inside and outside of dry-type transformer by lightning. If it is a serious situation, it is very easy to cause fire accidents, power failure, damage to machinery and equipment, etc.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?What is the wiring mode of dry-type transformer?

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?At rated power the ratio of output power to input power of transformer is called the efficiency of transformer, i.e. & ETA; Is the efficiency of the transformer; P is the input power and P is the output power.Wiring mode of dry-type transformer:Bidding,The representative mode of connection group of dry-type transformer is: English capital letters indicate the wiring on the primary side (or primary side), and English letters indicate the wiring on the secondary side (or secondary side). Y (or y) is star wiring, and D (or D) is triangular wiring.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 vibration reduction solution of cable bridge is to modify the hard connection between bus bridge and dry-type transformer, and the vibration reduction solution is made at the cable bridge.

Oil immersed transformer companyHigh value,When the transformer is put into operation,SanzakatBox type transformer room, if the tap changer is not in time,SanzakatOil sample test of oil immersed transformer, a great & ldquo; Tweet & rdquo; The high-voltage fuse is broken when the noise is serious; If the tap changer is defective, once the load increases, it is likely to burn the circuit breaker of the tap changer. In case of such situation, power off immediately for maintenance.Hand touch method for transformer inspectionLoose core screwSanzakat,What is the important role of power transformerPower transformer plantThe 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.
