220kv Off Load Tap Changer Oil Type Transformer / High Power
Transformer
Product Description:
1. Iron core
1. The iron core adopts cold-rolled crystal-oriented silicon steel
plate 30Z140 with high quality, low-loss, and no time effect,
sheared by Geroge line and with no burr. 1.2 Iron core adopts
pulling board structure, the upper and down yoke is clamped by
board, to form the frame structure. The iron core adopts advanced
lamination process, which effectively controls the no-load loss and
electro-magnetic noise.
2. Winding
2.1 Winding adopts mature structure, which ensure the reliability
of transformer operation.
2.2 The insulation power field intensity between turns shall be
controlled no greater than 1.6kV/mm.
3. Body
3.1 Body adopts mature insulation structure, and strictly guarantee
the main axial insulation margin.
3.2 Body mostly adopt multi-coil whole assembly, processed in
constant voltage and evaporation, which made coil shrink evenly and
with less rebounce, and enhance the electric strength and
mechanical strength.
3.3 Adopt laminating wood board or thermal shaped insulation
cardboard. Pressed tightly with pin, which ensure the winding is
constantly pressed tightly.
4. leading wire
4.1 The layout of all leading wire is reasonable, which guarantees
the enough electric distance and mechanical strenth.
4.2 All leading wire is cirlulized ,which guarantee the reliable
wild or prize connection.
5.2 Pipeline with gas relay such as the oil tube and bushing hoist
support on top of oil tank is with hoist gradient, to facilitate
the gas in transformer flow to gas relay.
5.3 Vacuum oiling is adopted, there is no leakage and permanent
distortion in the following test. vacuum-pumping :759mmHg load
voltage test: bear 2 times the oil pressure of oil conservator oil
surface for 24 hours.
5.4 The structure of transformer is convenient for disassembly and
change of bushing and porcelain element.
5.5 The oil drip valve is set on the bottom of oil tank, sampling
valve is set in the middle.
5.6 collective gas connecting tube is fixed on the bushing hoist
support.
5.7 Transformer is of full-sealed structure, the upper and down oil
tanks are required to welded fully.
6. Oil conservation tank
6.1 Adopt capsule type, finger type oil level indicator oil
conservation tank.
6.2 The structure is convenient for internal cleaning, the capacity
can ensure no oil overflow in 40 ambient temperature with full
load, and oil shall be seen from oil level indicator before put
into operation in 25
6.3 Oil conservation tank is equipped with oil-sealed moisture
absorber.
7. Safety protection device:
7.1 Gas relay is fixed in transformer, the standard complies with
ZBK41004-89Gas relay.
7.2 There is enough and reliable pressure release device, and
matched with oil spray pipe, the direction of oil spraying is
downward.
8. Oil temperature measuring device:
8.1 There is pipe support of mercury thermometer, which is set on
the top of oil tank.
