Abstract
The utility model discloses a kind of cable clamp structure that hydraulic generator rotor lead is bidirectionally limited.It is made of pin, backing plate, upper insulation plate, insulating sleeve, metal guide, lower insulation plate, metal caul and spring washer, nut.Wherein pin is divided into thread segment, and pin section, boss section three parts, boss section coordinate with metal caul interior grooves, other end thread segment by nut tight, to limit displacement of the rotor leading wire along pin axial direction.Pin section outer diameter is small―gap suture cooperation with metal caul endoporus, and pin can be prevented to be subjected to displacement along pin radial direction, to be limited along pin radial direction to rotor leading wire.The outer diameter of metal guide belongs to small―gap suture cooperation with lead endoporus outer diameter, is moved radially along pin prevented also from rotor leading wire.It is bidirectionally limited to rotor leading wire axis, radial direction to realize.
Description
Technical field：
The utility model is related to a kind of cable clamp structures that hydraulic generator rotor lead is bidirectionally limited；
Background technology：
Because rotor leading wire is mounted on rotary part, the wire clamp of fixed rotor lead need to ensure that rotor leading wire obtains
Permanent reliable limit.Rotor leading wire is drawn out to magnetic pole from collector ring, and traditional wire clamp is often using the shape axially or radially limited
Formula, such as lead in an axial direction use axial limiting wire clamp, radially the lead of horizontal direction, and wire clamp is limited using radial.Cause
Often there is the wire clamp of diversified forms on the path of rotor leading wire in this.Not only install in this way it is dumb, and if lead along axis
When to and rotatable parts outside diameter, axial wire clamp will bear centrifugal force, wire clamp bad stability at this time, be easy failure, lead
Rotor leading wire deformation, ground connection are caused, is caused the accident.
Invention content：The bidirectionally limited cable clamp structure of hydraulic generator rotor lead a kind of flexible for installation and safe, skill
Art scheme is：By pin (1), nut (2), spring washer (3), backing plate (4), upper insulation plate (5), insulating sleeve (6), metallic pin
(7), lower insulation plate (8), metal caul (9) composition are covered, pin (1) is sleeved in metal caul (9), insulating sleeve (6) are covered
Outside mounted in pin (1), metal guide (7) are sleeved in rotor leading wire, and upper insulation plate (5) is installed along with rotor leading wire
Between lower insulation plate (8), the pin (1) for covering insulating sleeve (6) passes through lower insulation plate (8), metal guide (7), with holes
Rotor leading wire and upper insulation plate (5) with nut (2) tight, are locked screw thread by spring washer (3) by backing plate (4)
Gu metal caul (9) is welded on above axis or rotor field spider.
The pin (1) is divided into thread segment (10), pin section (11), boss section (12) three parts, boss section (12) and gold
Belong to backing plate (9) to coordinate, by nut (2) tight, pin section (11) outer diameter is other end thread segment (10) with metal caul (9) endoporus
Small―gap suture coordinates.
The outer diameter of the metal guide (7) is small―gap suture cooperation with rotor leading wire endoporus outer diameter.
In the present invention, pin (1) is divided into thread segment (10), pin section (11), boss section (12) three parts, boss section
(12) coordinate with metal caul (9), other end thread segment (10) by nut (2) tight, to limit rotor leading wire along pin
(1) displacement of axial direction, pin section (11) outer diameter are small―gap suture cooperations with metal caul (9) endoporus, pin can be prevented along pin
(1) radial direction is subjected to displacement, to be limited along pin (1) radial direction to rotor leading wire.
In the present invention, between the outer diameter of the metal guide (7) and rotor leading wire endoporus outer diameter belong to small
Gap coordinates, and is moved radially along pin (1) prevented also from rotor leading wire.And metal guide (7) is by rotor leading wire and insulating sleeve
(6) it separates, to prevent rotor leading wire play from wearing insulating sleeve (6).
Operation principle：
Pin (1) boss (12) one end is sleeved in metal caul (9) by the utility model, and other end thread segment (10) is logical
Nut (2) is crossed tight, to limit displacement of the rotor leading wire along pin (1) axial direction, passes through the pin section (11) and gold of pin (1)
The small―gap suture cooperation for belonging to the small―gap suture cooperation and metal guide (7) and rotor leading wire endoporus of backing plate (9) endoporus, to limit lead
Along the displacement of pin (1) radial direction, so that such shaped cable clamp can have the function of that axis, diameter are bidirectionally limited simultaneously.
Technique effect：The bidirectionally limited cable clamp structure of the utility model rotor leading wire will pass compared with traditional cable clamp structure
The bolt of system is designed to the pin of special shape, and increases metallic sheath on the outside of insulating sleeve, to realize to rotor leading wire axis,
It is radial bidirectionally limited.This type of wire clamp can be used on entire rotor leading wire routing path in this way, only need to adjust gold
The height for belonging to backing plate adjusts the height of rotor leading wire, flexible for installation and safe.

Specific implementation mode：
The utility model is to provide the bidirectionally limited cable clamp structure of hydraulic generator rotor lead, as depicted in figs. 1 and 2,
The structure by pin 1, nut 2, spring washer 3, backing plate 4, upper insulation plate 5, insulating sleeve 6, metal guide 7, lower insulation plate 8,
Metal caul 9 forms, and pin 1 is sleeved in metal caul 9, and insulating sleeve 6 is sleeved on to the outside of pin 1,7 sets of metal guide
It in rotor leading wire, is installed along between upper insulation plate 5 and lower insulation plate 8 with rotor leading wire, covers the pin of insulating sleeve 6
