Causes and main aspects of transformer failure
May 21, 2021| (1) In the AC circuit loop, if the structure of the experimental wiring terminal in the loop is defective, and the quality of the terminal cannot be guaranteed, then the voltage transformer is likely to be affected by the extruder screw during the entire operation process. The problem of poor contact with the copper wire hole, resulting in a circuit lead.
(2) In the substation overhaul work of the AC circuit loop, if the relevant substation overhaul staff exhibits negligence in their work, such as forgetting to connect the car relay protection equipment in the circuit, the probability of common failures in the circuit operation will be reduced. Further improve.
(3) When the length of the connecting piece glue wood of the experimental terminal in the AC circuit loop is too long, the copper piece on the rotating terminal may not be able to press the connecting piece, and it cannot touch the connecting piece. On the top of the wood glue head, causing the circuit to lead the way.
(4) If the connection of the secondary line terminal is too loose and unreliable, then when the current in the AC circuit loop is too large, it is likely to cause the secondary line terminal connector to be burned and air oxidation
