Embodiment Construction

[0020] see Figure 1 to Figure 3 As shown, the present invention is a magnetic shunt pressing device with a tightening band structure, which is arranged between the core clip 1 and the coil, and includes a ring nut 2, a tightening band 3, a pressing block 4, and a magnetic shunt 5. Described draw ring nut 2 comprises nut 6, pin 8, stop ring 9, circular ring 7, and described nut is provided with square body, is used for nut tightening, and described circular ring is fixed on the nut with pin, The stop ring is welded on the pin, and the pin, the stop ring and the ring cooperate, and the ring can rotate freely. A baffle 11 is fixed at both ends of the briquetting block to prevent the tightening belt from slipping off from the briquetting block 4 , and a handle 12 is arranged on the baffle.

[0021] The ring nut 2 is connected to the iron core clip 1 by using the original bolts on the clip to fix the pull plate. The bolt has an inclination angle, which can ensure that the positio...

Abstract

The invention provides a magnetic shunt compaction device of a tightening belt structure. The magnetic shunt compaction device of the tightening belt structure comprises a pull ring nut, a tightening belt and a pressing block, wherein a freely rotating round ring is arranged on the nut and a manual tightening device is arranged on the tightening belt. By arranging a compaction area between a clamping piece and the tightening belt, the tightening belt provides a tightening force to control a gap between a magnetic shunt and a magnetic core main pole.

Description

technical field [0001] The invention provides a device for reducing magnetic flux leakage of a transformer, in particular to a magnetic shunt compacting device with a tightening belt structure. Background technique [0002] With the development of my country's electric power industry, large-capacity, high-voltage large-scale power transformers have become the development direction of the transformer industry. The power transformer causes a large amount of power loss during the power transmission process, and the magnetic flux leakage is an important factor affecting the loss of the transformer, and its size has an increasingly important impact on the performance of the transformer. Effectively reduce magnetic flux leakage. [0003] The magnetic shunt is installed between the iron core clamp and the coil. Since the diameter of the super-large transformer coil can generally reach 2 to 3 meters, and the radius is greater than 1 meter, the magnetic shunt is generally installed ...
