Dry type transformer manufacturer
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.
BeckyHand touch method for transformer inspection
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.

When the screw of the through core extruder holding the iron core of the transformer is loose， there are screw cap parts left on the iron core， or small metal materials fall into the transformer， the transformer will send out & ldquo; Ding Ding Dang & rdquo; Or & ldquo; Call & hellip; Call & hellip& rdquo; Blowing sound and its & ldquo; Squeak squeak & rdquo; It"s like a magnet sucking a small washer， while the working voltage，BeckyWorking principle of power transformer， current and temperature of the transformer are all normal. Such conditions generally do not endanger all normal operation of the transformer， and can be solved until power failure.
For no-load impulse closing of transformer， pay attention to the following matters:
Plug in the power with full load first， observe and detect that the input and output voltage meets the regulations. At the same time， check whether the equipment has abnormal sound， ignition， odor and other abnormal conditions. If there is any abnormality， please cut off the input switching power supply.
During the operation of the transformer， the resistance value of the grounding wire shall be measured accurately every two years.
For kVA power engineering transformer， clamp and electromagnetic coil to keep the electromagnetic coil in a stable clamping state to reduce noise.
Welcome calls What is the reason for the shutdown of power transformer?
The main reason is that the welding quality of electric welding is poor， there are empty welding， open welding， needle holes， sand holes and other shortcomings in welding. The oil transformer is easy to be covered with welding powder and paint when leaving the factory， and the potential safety hazards are exposed after operation. In addition， the electromagnetic induction vibration will crack the electric welding and lead to leakage.
Solenoid insulation deterioration
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.
Customer firstThe iron core of power transformer is made of high-quality crystallized hot-rolled ferrite core， which is stacked at the degree fully inclined multi-step interface. The surface is covered with epoxy resin adhesive cable sheath coating， which is resistant to corrosion and rust， the transformer can be plugged in for trial operation after careful inspection before capital investment. During the trial operation period， you must pay attention to the following points. Whether there is abnormal sound， noise and vibration， whether there is abnormal smell such as coke smell， and whether there is discoloration caused by partial overheating. Ventilation is good. In addition， we should also pay attention to the following aspects.
Oil immersed transformer operation
Becky(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.
Power transformer is one of the key equipment in power station and substation. The function of power transformer is in all aspects. It can not only raise the voltage and send electromagnetic energy to the power consumption area but also reduce the voltage to each application voltage，Becky2500kVA dry type transformer， voltage transformation and blood pressure reduction must be carried out by the transformer.
The noise of dry-type transformer is mainly the vibration noise in operation. This vibration noise is caused by multiple positions， including the vibration of magnetic induction electromagnetic coil. All pay great attention to the solution of vibration when carrying out noise control.
