Nowadays, faults are inevitable during the use of incoming line reactors. However, due to their crucial regulatory role in the entire power system, no mistakes are allowed. Immediate handling should be carried out at that time to eliminate future problems. Specifically, the common faults and handling methods of incoming line reactors include the following aspects:

I. Fault of excessively high local temperature

If the temperature of the incoming line reactor is found to be too high during operation, this situation will accelerate the aging of the polyester film and even cause a series of changes, eventually leading to a short circuit and causing a fire. Therefore, this is very dangerous and should be detected and dealt with in a timely manner. The manufacturer of the incoming line reactor introduces that the reasons for this situation are very likely to be due to the quality of welding. If the welding is not in place, additional resistance will be generated, causing heating. Or it could also be that the design structure of the product itself is not conducive to heat dissipation. For these situations, on the one hand, ventilation and heat dissipation should be strengthened, and the operating environment temperature should be reduced. At the same time, the manufacturer of the incoming line reactor reminds that if there is any, the machine should be turned off and cleaned and maintained to ensure that all the ventilation points of the pipeline are unobstructed.

Ii. Surface discharge fault

Since a large part of the entire power system is located outdoors, the incoming line reactors are also affected by many natural factors outdoors, including rain, wind, lightning, dust, etc., which can cause certain impacts and even lead to leakage or voltage fluctuations. To prevent or solve the problems that have already occurred, corresponding measures should be taken. A comprehensive range of incoming line reactor manufacturers introduce that, for instance, insulating materials can be applied to the surface of the equipment, and pre-burial treatment can be carried out at both ends of the coil. At the same time, rainproof measures can be installed for the incoming line reactor, etc.

Iii. Fault of burnout of the lead joint of the series reactor

Domestic professional incoming line reactor manufacturers introduce that this type of fault is also a frequently occurring type. Usually, when this problem occurs, it is largely due to short circuits. To ensure the operational needs of the entire power grid, countermeasures should be taken immediately. The manufacturer of incoming line reactors emphasizes that this issue should be taken into account during the design process, and preventive measures should be adopted to prevent loosening and other phenomena at the relevant connection points.

The above are the common faults of the incoming line reactor and several aspects of their solutions. In addition, there may be the phenomenon of the tap reactor burning out. This kind of fault is very likely caused by errors during installation, such as improper connection of the lead joint or loosening. The manufacturer of the incoming line reactor emphasizes the need for timely handling, as this component exists to enhance the working efficiency of the discharger, and thus it must be well protected.
