Description

A new type of connecting wire between poles of generator

technical field

The utility model relates to a novel connecting wire between poles of a generator, which belongs to the technical field of generator manufacturing.

Background technique

In the currently known hydroelectric generator sets, the rotor magnetic pole coils need to be connected by inter-pole connection wires and magnetic pole lead-out wires to form an excitation winding. The inter-pole connection wires are generally made of copper busbars of specified specifications. Not less than the area of the copper bar of the coil. At present, this part is generally made of fixed copper busbar or copper flat wire. The bending angle is relatively large, and the space required for rotor installation is large. The connection line needs to be fastened by a special shim after the installation is completed. When the space of the entire rotor is tight, the arrangement of the shim will be very difficult, which will easily cause local space waste or local space shortage. Many installations in power stations It needs to be adjusted according to the actual situation, causing unnecessary trouble to the installation of the generator.

Utility model content

In order to solve the above-mentioned problems or shortcomings, the utility model provides a connecting line between poles of a generator that is easy to install and saves space.

In order to achieve the above purpose, the connecting line between the poles of the generator of the utility model is realized according to the following technical scheme:

The new generator inter-pole connecting wire includes an inter-pole connecting wire body, which is characterized in that: the inter-pole connecting wire body is processed by copper plate, and there are two connecting holes on the left and right sides of the lower end, and the inter-pole connecting wire body passes through The connecting holes are connected with the two screw rods of the rotor yoke itself.

The beneficial effects of the utility model are: the fastening effect of the connecting wire between the poles is good, the integrity of the rotor is improved, the size of the processed parts of the connecting wire body between the poles is random, the shape can be determined according to the actual situation, and the space of the connecting wire can be tight. Easy to operate and easy to install, saving time.

Wherein the reference numerals are represented as: 1-interpolar connecting wire body, 2, 3-connecting hole, 4-rotor yoke, 5, 6-screw.

Detailed ways

Below in conjunction with accompanying drawing and embodiment, further illustrate the utility model.

As shown in Figure 1, the traditional generator magnetic pole coils 13 need to be connected by the traditional inter-pole connection wire 11 and some magnetic pole lead-out wires to form the excitation winding. The bending angle is relatively large, and the space required for the installation of the rotor is large. The traditional inter-pole connection line 11 made of copper busbar bending needs to be fastened by a special pad iron 12 after installation. In the case of tight space, the arrangement of the horn 12 is very difficult, which may easily cause local space waste or local space shortage. Many installations in power stations need to be adjusted according to actual conditions, causing unnecessary trouble to generator installation.

As shown in Figures 2 and 3, the new generator inter-pole connecting wire includes an inter-pole connecting wire body 1. The inter-pole connecting wire body 1 is made of copper plates, and there are connecting holes 2 and 3 on the left and right sides of the lower end respectively. The connecting wire body 1 is respectively connected to the two screw rods 5 and 6 of the rotor yoke 4 itself through the connecting holes 2 and 3 . Due to the good fastening effect of the connecting wire body 1 between poles, the integrity of the rotor can be improved, and the size of the workpiece of the connecting wire body 1 is arbitrary, and the shape can be determined according to the actual situation. Easy to install and save time.

The above embodiments are only used to illustrate the technical solutions of the present utility model, and cannot limit the scope of the present utility model; modifications to the technical solutions recorded in the foregoing embodiments, or equivalent replacements to some of the technical features, and All should still fall within the scope covered by the utility model patent without making the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the utility model.
