The variation of oil level can be monitored in the meter of position.The volume of conservator is generally the 8%~10% of oil tank of transformer institute charge of oil volume.
Five, insulating sleeve.The lead-out wire of transformer winding is pierced by when fuel tank is drawn out of case and has to pass through insulating sleeve, with
Make the lead wire insulation of electrification.Insulating sleeve is mainly made of central conductor leader and magnetosheath.The one end of conducting rod in fuel tank with around
Group connection, one end and outer connection outside.The structure of insulating sleeve depends primarily on voltage class.Low general of voltage
Using simple solid magnetosheath pipe.
Six, tap switch.Tap switch is the device for adjusting transformation ratio.The first winding and three winding of two-winding transformer
One secondary winding of transformer generally has 3,5,7 or 19 tap joint positions, and the intermediate of tap is voltage rating separately
Position.The adjacent parted hair voltage phase difference 5% of 3 taps, the adjacent parted hair voltage phase difference 2.5% or 1.25% of multiple parted hairs.
Operation part is loaded on transformer top, and the fuel tank of transformer is protruded into through drive rod.According to the needs that system is run, as indicated
Mark the position to select tap.
Seven, gas relay.The protection that gas relay is constituted is one of main safeguard measure of transformer, it can
To reflect the various failures and abnormal operating condition of inside transformer, such as oil level decline, insulation breakdown, iron core, winding dampness,
Discharge faults such as fever etc., and it is sensitive rapid, structure line is simple, and Maintenance and Repair are convenient.
