Description

A kind of high voltage isolator shaft coupling

Technical field

The utility model belongs to power high voltage isolating switch technical field, particularly relates to a kind of high voltage isolator shaft coupling.

Background technology

At present, isolating switch is one of visual plant in electric power system, and along with the reliability of grid disruption road device improves constantly, isolating switch Problems existing becomes increasingly conspicuous.Therefore, improving the operational reliability of isolating switch, is current raising system reliability, ensures the task of top priority of power system security, stable operation.

Because domestic each high-voltage switch gear producer is not enough to isolating switch production attention degree, production management is backwardness relatively, all there is certain problem in technique, material, isolating switch defect is caused to take place frequently, individual plants time of even putting into operation is very short, just start the major defects such as tripping, transmission mechanism distortion, the heating of conductive body contact position occur, reduce equipment dependability, system safety stable operation cannot be effectively guaranteed.Putting into operation less than in one-year age, also repeatedly there is the major defects such as transmission mechanism distortion, contact site heating in our factory isolating switch, stopping transport and overhauling, having had a strong impact on the economic benefit of company to making equipment.

Isolating switch electric conductor heating main cause is because electric conductor place support cover is PBT plastic material, and product occurs aging fracture after long-time running at the scene.Electric conductor is chronically exposed in outdoor air, is subject to damp vapour and air-polluting impact generation corrosion, causes electric conductor surface contact bad, make electric conductor temperature too high under the effect of big current.

Utility model content

The utility model easily generates heat for solving existing isolating switch electric conductor, gets rusty, the problem that surface contact is bad and provide the high voltage isolator shaft coupling that a kind of structure is simple, easy to install, increase work efficiency.

The technical scheme that the utility model is taked for the technical problem existed in solution known technology is:

The high voltage isolator shaft coupling of the utility model embodiment, this high voltage isolator shaft coupling comprises: coupling, silver-plated soft copper band, the first button contact base, the second button contact base, the first boss, the second boss;

First button contact base and the second button contact base are arranged on the side of coupling, and the first boss is arranged on the tail end of the first button contact base, and the second boss is arranged on the tail end of the second button contact base, and silver-plated soft copper band is fixedly connected with by the screw of the first boss with the second boss.

The utility model can also adopt following technical measures:

The advantage that the utility model has and good effect are: because the utility model adopts conductive strips bolt connection type conductive structure; Improved button contact base two respectively increases a boss, when not affecting fingertip scope of activities, can play and stop that fingertip runs off the effect of anchor point, after button contact base assembling, to be screwed with the boss of button contact base with silver-plated soft copper band at the tail end of each button contact base and to be connected, ensure that the clean of contact-making surface, contact resistance is stablized constant, avoid the generation of the phenomenon of scaling loss fingertip.Structure of the present utility model is simple, easy to use, solves existing isolating switch electric conductor preferably and easily generates heat, get rusty, the problem that surface contact is bad.

Accompanying drawing explanation

Fig. 1 is the high voltage isolator shaft coupling structural representation that the utility model embodiment provides;

In figure: 1, coupling; 2, silver-plated soft copper band; 3, the first button contact base; 4, the second button contact base; 5, the first boss; 6, the second boss.

Embodiment

For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows.There is not the innovation of software or method in the utility model.

Refer to Fig. 1:

As shown in Figure 1, the utility model embodiment high voltage isolator shaft coupling primarily of: coupling 1, silver-plated soft copper band 2, first button contact base 3, second button contact base 4, first boss 5, second boss 6 form;

First button contact base 3 and the second button contact base 4 are arranged on the side of coupling 1, first boss 5 is arranged on the tail end of the first button contact base 3, second boss 6 is arranged on the tail end of the second button contact base 4, and silver-plated soft copper band 2 is fixedly connected with by the screw of the first boss 5 with the second boss 6;

The utility model transform former shaft coupling slidingtype fingertip conduction as conductive strips bolt connection type conductive structure; Improved button contact base two respectively increases a boss, when not affecting fingertip scope of activities, can play and stop that fingertip runs off the effect of anchor point; After button contact base assembling, to be screwed with the boss of button contact base with silver-plated soft copper band at the tail end of each fingertip and to be connected; Ensure that the clean of contact-making surface, contact resistance is stablized constant, the phenomenon of scaling loss fingertip just not there occurs.

The utility model solves the defect of deciliter operation bite of shaft coupling electric conductor heating accident and isolating switch, almost there is not generation, the loss of outage caused because isolating switch electric conductor is overheated is effectively avoided after transformation, enhance the stability of equipment safety operation, solid foundation has been established in the safety in production for Utilities Electric Co..

The above is only to preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, every according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
