Problems solved by technology
The magnetic shield of the device body is made of silicon steel sheets bonded with resin. Its installation position is between the upper iron yoke and the end of the coil. Due to its heavy weight and large size, it is easy to crack, so it cannot be used when the coil is compressed. Apply force to the magnetic shield of the body through the positioning nails on the clamp to compress the coil

Embodiment Construction
[0012] A 1000kV reactor soft belt pressing device, including an upper iron yoke 1, a backing plate 3 between the upper iron yoke 1 and a coil 7, and a magnetic shielding plate 2 between the upper iron yoke 1 and the backing plate 3, and also includes The pressing device 4 and the soft belt 5 fixed on both sides of the magnetic shielding plate 2 on the backing plate 3, the pressing device 4 is two long plates with grooves along the length direction of its upper surface, and the soft belt 5 Located in the groove, the two ends are installed with sealing clips 8 for sealing the ports of the soft belt 5, preventing the transformer oil from flowing out from the soft belt 5 and keeping the airtightness of the soft belt 5. The upper iron yoke 200mm grows respectively on both sides of the pressing device 4, and the soft belt 5 both sides in the groove each grows more than the upper iron yoke 200mm, which is convenient to install the sealing clip 8 at the soft belt 5 ports. A U-shaped g...

The invention discloses a soft band compaction apparatus for a 1,000kV electric reactor. The soft band compaction apparatus comprises an upper iron yoke, a base plate positioned between the upper iron yoke and a coil, and a magnetic shielding plate positioned between the upper iron yoke and the base plate; the soft band compaction apparatus is characterized by further comprising compaction apparatuses and soft bands fixed on the two sides of the magnetic shielding plate on the base plate; the compressing apparatuses are two long plates, wherein grooves are formed in the two long plates along the upper surface length direction; the soft bands are positioned in the grooves; and sealing clamps for sealing the ports of the soft bands are mounted at the two ends of the soft bands. According the soft band compaction apparatus, the coil is compressed tightly by filling the soft bands with oil; the coil height of an extra-high voltage electric reactor is effectively ensured; the problem of the cracking of the magnetic shielding caused by that the magnetic shielding is damaged due to positioning nails on the clamp parts is avoided; and the soft band compressing apparatus provides forceful support for ensuring that the electric reactor can pass the finished product test.
Description
technical field [0001] The invention relates to a device for compressing a reactor coil, in particular to a 1000kV reactor soft belt pressing device. Background technique [0002] Since the body structure of the 1000kV reactor adopts the magnetic shielding structure of the body, it is used to reduce the magnetic flux leakage. The magnetic shield of the device body is made of silicon steel sheets bonded with resin. Its installation position is between the upper iron yoke and the end of the coil. Due to its heavy weight and large size, it is easy to crack, so it cannot be used when the coil is compressed. Apply force to the magnetic shield of the body through the positioning nails on the clamp to compress the coil. Contents of the invention [0003] In view of the above problems, the present invention provides a flexible belt pressing device for a reactor. By filling the flexible belt with oil and pressurizing it, the soft belt expands and compresses the coil to ensure the ...
