Embodiment 1

[0027] Embodiment 1: as image 3 , 4 As shown, an insulating positioning rod 2 for making a hollow annular reactor is characterized in that: the insulating positioning rod 2 is a long strip insulating rod body, and a positioning groove 3 is opened on the outer surface of the insulating rod, and the positioning groove 3 The size and shape of the reactor winding match the size and shape of the reactor to ensure that the reactor winding is positioned through the positioning groove 3 of the insulating positioning rod 2; the insulating positioning rod 2 is designed according to the number of turns and the size of the hollow ring reactor 1 Matching with it, the slotted cross-sectional shape of the insulating positioning rod 2 is rectangular, the slotting direction of the insulating positioning rod 2 intersects the central axis of the insulating positioning rod 2 at an acute angle, and is arranged obliquely relative to the central axis axis, so The material of the insulating positio...

Embodiment 2

[0029] Embodiment 2: as Figure 6 As shown, compared with Embodiment 1, the only difference is that the slotted cross-sectional shape of the insulating positioning rod 2 is circular.

Embodiment 3

[0030] Embodiment 3: as Figure 7 to Figure 9 As shown, compared with Embodiment 1, the only difference is that the slotted cross section of the insulating positioning rod 2 is trapezoidal, and the slotting direction is parallel to the central axis of the insulating positioning rod 2 .

[0031] In summary, the present invention provides an insulating positioning rod for making a hollow annular reactor and a method for manufacturing the reactor. The hollow annular reactor made by using the insulating positioning rod does not need to half-fold the insulating material on the reactor winding. , which reduces the manufacturing cost and improves the production efficiency; the reactor winding passes through the positioning slot of the slotted insulating positioning rod, which ensures reliable positioning and greatly reduces the risk of inter-turn short circuit; the positioning of the reactor winding through the slotted insulating positioning rod The grooves are used to reliably locat...

Abstract

The invention discloses an insulation locating bar for manufacturing a hollow circular electric reactor. The insulation locating bar for manufacturing the hollow circular electric reactor is characterized in that the insulation locating bar is a long-strip-shaped insulation bar body, and locating grooves are formed in the outer surface of the insulation bar body. The invention further discloses a manufacture method for manufacturing the hollow circular electric reactor by adopting the insulation locating bar. The method comprises the following steps: each turn of an electric reactor winding is inlaid in the locating grooves respectively, the electric reactor winding and the insulation locating bar are fixed through insulation flat armor belts, and finally the hollow circular electric reactor is formed by embedment, fixing and forming through insulation materials. The hollow circular electric reactor manufactured by using the method does not need to half cover insulation materials on the reactor winding, cost is reduced, and efficiency is improved. The reactor winding is enabled to obtain reliable locating guarantee through the locating grooves, and the risk of short circuit among turns is greatly reduced. Through the reliable location of each turn of the reactor winding by the locating grooves, the positions and distances among turns are enabled to be guaranteed reliably, and the uniformity of reactor products is improved.

Description

technical field [0001] The invention relates to a manufacturing tool for a reactor and a method for manufacturing the reactor, in particular to a manufacturing tool for making a hollow ring reactor and a method for manufacturing the hollow ring reactor. Background technique [0002] During the production and processing of hollow toroidal reactors, the traditional turn-to-turn insulation treatment method is: half-wrapping insulating materials such as polyimide film and seamless glass ribbon on the winding. However, due to the special structure of the reactor, the operating space is too small, and the actual operation is too difficult, time-consuming and labor-intensive, and the efficiency is very low when the insulating material is half-folded; [0003] Usually, there is only half-stacked insulating material between the turns of the reactor, and there is no other reliable positioning. During the subsequent operation, it is easy to cause damage to the inter-turn insulation, re...
