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.

Banjo GoreOvertemperature alarm and trip: collect winding or iron core temperature data signals according to the temperature measurement resistor of PTC discrete system thermistor embedded in the bottom voltage winding. When the transformer winding temperature rises again， if it reaches ℃， the system software outputs the overtemperature alarm system; If the temperature rises to ℃ again and the transformer can no longer operate， the overtemperature trip data signal must be transported to the secondary maintenance circuit， and the transformer shall be tripped quickly.
How much is the power transformer
LapekaCaused by sand holes and cracks. For crack leakage， drilling stop hole is a good way to remove in-situ stress and prevent widening.
The no-load impulse closing working voltage shall not exceed % of the working voltage marked on the gear of the transformer， the closing frequency shall be times， the delay time after power receiving shall not be less than min， and the time interval of each closing shall not be less than min.
If you want to check the activated carbon fiber for the hanging cover first take out the low-voltage waterproof sleeve and the on load transformer power switch， then lower the bell cover anchor bolt of the large cover， wear round steel from top to bottom in the surrounding screw holes， and count the spacing and specifications for easy reinstallation. At the same time the cable wind shall be added on all sides to ensure that the core international body will not be damaged during the whole lifting process. After lifting for mm， stabilize the bell cover， and check the bearing capacity of the lifting core， center of gravity and Jack. After everything is normal， lift it again until the bell cover exceeds the relative height of the body， and rotate the crane to place the bell cover on the clean skid.
When the new oil filled by the power transformer and the oil sample that has just been considered are used，Banjo GoreWhich is better for dry-type transformer， the oil sample can be used only after sufficient standing.
It should be said that after the development trend of these years， the overall level of China"s transformer industry at this stage is basically international， and the quality level is no different from that of overseas goods& rdquo; The person in charge of the transformer Federation of China Household Appliance Industry Association said.
In terms of the place of use， dry-type transformers are mostly used in & ldquo; Fireproof and explosion-proof type & rdquo; It is easy to use in large and medium-sized engineering buildings and multi-storey buildings; The oil immersed transformer because of & ldquo; Accident & rdquo; There is likely to be oil or leakage after fire， and most application places leading to fire accidents are easy to choose in large and medium-sized engineering buildings and multi-storey buildings;
Affordable priceDry type transformer manufacturer
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，Banjo GoreDry type transformer industry ranking，Banjo GoreBox transformer 500， the electromagnetic induction vibration will crack the electric welding and lead to leakage.
Due to poor sealing， generally， the sealing of box edge and machine cover is sealed with acid-base resistant rubber rod or rubber plate. If the joint is not solved well， it will lead to common faults of oil leakage.

Banjo GoreGenerally speaking， the ignition emergency treatment method of oil immersed transformer is mainly to disconnect the oil immersed transformer， disconnect the switching power supply on each side， quickly invest the reserved oil immersed transformer and start the power supply system from scratch. Stop the operation of refrigeration equipment. Key oil immersed transformer ignition. When L-type oil immersed transformer and high voltage station oil immersed transformer are ignited
