Abstract

The utility model discloses a novel generator conductive rod structure. The structure comprises two conductive plates, cross sections of which are in arc shape. The two conductive plates are arranged oppositely up and down and along the same axis. Radial inner surfaces of the two conductive plates are connected together by two or more sets of insulating fasteners, which are in screwed connection with each conductive plate. Each set of insulating fasteners include two insulating fasteners arranged centrosymmetrically along the axis of each conductive plate. Conductive blocks are welded onto one side ends of the two conductive plates respectively and are provided with screw holes for connecting conductive screws of a main motor rotor. Radial outer surfaces of the conductive plates are wrapped by conductive rod insulating layers. The structure is simple in structure and convenient for use. The conductive plates with the arc-shaped cross sections are used to replace solid copper conductors in the prior art, so that the whole conductive rod is largely reduced in weight, which is about 20% of that of a conventional conductive rod, and thus the labor intensity of assembling is reduced. Besides, production costs are reduced, and the production efficiency is improved.

Description

Novel electricity generator conducting rod structure

Technical field

The utility model relates to a kind of electric generator rotor coil power supply part, particularly a kind of generator amature conducting rod.

Background technology

Conventional generator is generally two lobe solid copper conductors (positive negative), the outside bag insulation of conductor, last outside suit insulating sleeve to the conducting rod of main rotor power supply.There are following shortcoming 1. Heavy Weights in this kind of structural conductive bar; 2. because the outside bag insulation of conductor rear surface viscosity is large, insulating sleeve is installed difficulty, and production efficiency is low.

Utility model content

The purpose of this utility model is to provide a kind of generator conducting rod structure lightweight, reliable, easy for installation.

For achieving the above object, novel electricity generator conducting rod structure of the present utility model comprises two conductive plates that cross section is curved, the upper and lower relative spacing of two conductive plates and being coaxially set, between two conductive plate inner radial surface, interconnect by insulating fixing piece more than two, insulating fixing piece and each conductive plate are all screwed together; Every group of insulating fixing piece comprises symmetrically arranged two insulating fixing piece of axis centre about conductive plate; Described two conductive plate one side ends are welded with respectively conducting block, and conducting block is provided with the screw for connecting main rotor contact screw; On the radially-outer surface of described two conductive plates, be enclosed with conducting rod insulating barrier.

NOMEX insulating paper and mica tape that described conducting rod insulating barrier is wrapped in by intersection on the radially-outer surface of two conductive plates form.

The utlity model has following advantage:

1. the utility model is simple in structure, easy to use, uses the curved conductive plate in cross section to replace solid copper conductor in the past, whole conducting rod weight is greatly reduced, be about 20% of the conventional conducting rod weight of same model, thus the working strength while having alleviated assembling, and greatly reduce manufacturing cost.

2. owing to having cancelled the insulating sleeve (conducting rod sleeve pipe) of conventional conducting rod outside, therefore greatly reduced the workload of suit insulating sleeve, conducting rod production difficulty, cycle are reduced greatly, save the consumption of effective material, improve production efficiency, there is higher economic benefit and technique superiority.

3. NOMEX insulating paper is current material, and its composition is aromatic polyamide, has good dielectric strength, mechanical tenacity, flexibility, anti-flammability and resilience; And insensitive to humidity, in the time spending humidity 95% mutually, its dielectric strength also can reach 90% under bone dry state; Mica tape is also current material, has good resistance to elevated temperatures and flame resistance energy; NOMEX insulating paper and mica tape intersection are wrapped on the radially-outer surface of conductive plate, form double-layer insulating structure, give full play to the Inherent advantage of bi-material, have good insulation property.

Embodiment

As depicted in figs. 1 and 2, novel electricity generator conducting rod structure of the present utility model comprises two conductive plates that cross section is curved, two conductive plates relative spacing and being coaxially set Shang Xia 1, between two conductive plate 1 inner radial surface, interconnect by insulating fixing piece 2 more than two, insulating fixing piece 2 is all screwed together with each conductive plate 1; Every group of insulating fixing piece 2 comprises symmetrically arranged two insulating fixing piece 2 of axis centre about conductive plate 1; Described two conductive plate 1 one side ends are welded with respectively conducting block 3, and conducting block 3 is provided with the screw (screw is routine techniques, and figure does not show) for connecting main rotor contact screw; On the radially-outer surface of described two conductive plates 1, be enclosed with conducting rod insulating barrier 4.

NOMEX insulating paper and mica tape that described conducting rod insulating barrier 4 is wrapped in by intersection on the radially-outer surface of two conductive plates 1 form.

The utility model replaces solid copper conductor in the past with the curved conductive plate 1 in cross section, and whole conducting rod weight is greatly reduced, and is about 20% of the conventional conducting rod weight of same model, thus the working strength while having alleviated assembling, and greatly reduce manufacturing cost.

Above embodiment is the unrestricted the technical solution of the utility model in order to explanation only, although the utility model is had been described in detail with reference to above-described embodiment, those of ordinary skill in the art is to be understood that: still can modify or be equal to replacement the utility model, and not departing from any modification or partial replacement of spirit and scope of the present utility model, it all should be encompassed in the middle of claim scope of the present utility model.
