Technical Field

The utility model relates to a strutting arrangement reaches instrument external member including a plurality of this kind of strutting arrangements. In particular, it relates to a support device for supporting a high-voltage coil from an interior space when the high-voltage coil having a central chimney-like angle ring is nested into a voltage regulating coil, the support device being supported between a pair of hoisting stringers, thereby avoiding adverse effects of the hoisting stringers on the high-voltage coil in a radial direction.

Background

According to the conventional nested coil structure of the high-voltage coil and the voltage regulating coil, the high-voltage coil with a smaller diameter and the voltage regulating coil with a larger diameter are respectively wound, and then the coils with different outer diameters are assembled together. The pressure regulating coil with the larger outer diameter is sleeved outside the high-voltage coil with the smaller diameter (the large sleeve is small and is also called as a positive sleeve) from top to bottom, so that the coil assembly is completed. When the middle part of the high-voltage coil is provided with a lead outlet and a chimney angle ring structure (as shown in a schematic diagram of fig. 1), the local radial direction of the angle ring protrudes outwards, so that a path for sleeving the voltage regulating coil from top to bottom is blocked, and a conventional nested coil assembling method cannot be adopted.

Therefore, when the high-voltage coil is provided with a chimney-shaped angle ring in the middle, it is a conventional practice to wind the voltage regulating coil on the radially outer portion of the high-voltage coil, i.e., in a sleeving manner.

There is thus a need for a way to reduce the time taken for a coil edger station. The voltage regulating coil can be divided into an upper part and a lower part, then the high-voltage coil is reversely sleeved (small inserted into large) into the lower voltage regulating coil, and then the upper voltage regulating coil is hung outside the high-voltage coil. The chimney-like angle ring is located between the upper and lower regulator coils as shown in fig. 1. When the high-voltage coil is reversely sleeved into the lower pressure regulating coil, the high-voltage coil is hooked up from the inside of the high-voltage coil by using an axial hoisting beam of the cross hoisting beam (or other top hoisting structures). However, when the high-voltage coil is hoisted by adopting the mode in the reverse sleeving manner, the axial hoisting beam can cause the high-voltage coil to deform in the radial direction, and the high-voltage coil can be damaged.
