Under normal circumstances, baoding dry - type transformer without maintenance. However, in places where there is a lot of dust or harmful substances, special attention should be paid to the bottom and end of insulators and windings for dust accumulation during inspection, and load monitoring and regular experiments should be conducted on baoding dry type transformer.

(1) inspection and inspection of dry transformer maintenance

Under normal circumstances, baoding dry - type transformer without maintenance. However, in dusty or hazardous places, special attention should be paid to the bottom and end of insulators and windings. No more than two atmospheres of compressed air can be used to clean the air ducts and surface dust. During the normal operation inspection, no touch is allowed, and attention should be paid to whether the fastening parts are loose and hot, whether the insulation surface of the winding has cracks, creepage and carbonation traces, and whether the sound is normal.

(2) load monitoring for dry type transformer maintenance

The dry type transformer has strong overload capacity and can allow short overload time.

According to IEC905 load guide for dry power transformer, guide transformer overloading operation. Different ambient temperatures (shadr) and initial loads (PV) have different PPV capacities for the baoding dry transformer.

Baoding dry type transformer generally USES natural air cooling (AN), continuous output 100% capacity. If equipped with an air cooling system and forced air cooling (AF), the output capacity can be increased by 40%.

Temperature control system realizes temperature detection and control of transformer through temperature control box and PTC temperature measuring element installed in low-voltage winding. The temperature control box is equipped with the self-cooling variable voltage master, the transformer winding temperature exceeds the safe value, and the temperature control box will send a signal. The temperature control box of forced air cooling shall be able to stop starting the cooling fan and send out the alarm signal of over-temperature and over-temperature trip signal.

Baoding dry type transformer winding and iron core the highest temperature should not exceed 155 ℃, the highest temperature 100 k.

In the overload operation should pay close attention to changes, do not damage insulation due to too high temperature, unable to resume operation.

(3) periodic test cycle of dry type transformer

The regular test period of baoding dry type transformer is generally 3 ~ 5 years.
