Abstract
The composite guide sleeve for the vacuum arc-extinguishing chamber comprises a guide sleeve 1, wherein a lining 2 is arranged on the inner ring of the guide sleeve 1, and a composite material layer 3 is coated on the inner surface of the lining 2. The vacuum arc-extinguishing chamber effectively prevents the phenomenon of over-loose or clamping stagnation of the guide sleeve and the movable conducting rod which are easy to occur in the using process of the vacuum arc-extinguishing chamber, and optimizes the design of the matching tolerance. The vacuum arc-extinguishing chamber has the characteristics of low manufacturing cost, easy installation and use and good use effect under the condition of not changing the existing structure of the vacuum arc-extinguishing chamber. The vacuum arc-extinguishing chamber can be used in various vacuum arc-extinguishing chambers with existing structures.
Description
The utility model relates to a kind of fairlead, the fairlead that particularly a kind of vacuum interrupter is used.
In the present employed vacuum calamity arc chamber, a fairlead is housed all, its effect mainly is when the moving conductive rod of vacuum interrupter is pumped, the moving contact of its drive and its moved in coaxial, and guarantee that dynamic and static contact satisfies the requirement of plane contact.In use there are some problems in existing fairlead, mainly is to use in the process incident pine or the catching phenomenon of cooperating between fairlead and the moving conductive rod.The material that is used for making fairlead at present mainly is nylon 6 or metal materials such as nylon 1010, brass.The fairlead that adopts nylon 6 or nylon 1010 to make, the coefficient of expansion is big, and tolerance is little, and when the temperature step-down, the internal diameter of fairlead shrinks, and very easily with the moving conductive rod locking, switch tripping phenomenon occurs, causes the accident; Tolerance is big, when temperature is high, can cause fit clearance loose excessively, and contact contacts weak effect, influences the operate as normal of vacuum interrupter.With metal fairleads such as brass, in use, fairlead easily and oxygen-free copper glue together, and have distributary phenomenon.
The purpose of this utility model is: the compound direction cover that provides a kind of vacuum interrupter to use, it can prevent from easily to cooperate pine or catching phenomenon, and its cost of manufacture is low between the fairlead and moving conductive rod in the use effectively.
The utility model is achieved in that the formation of the compound direction cover that vacuum interrupter uses comprises fairlead (1), and characteristics are, the inner ring of fairlead (1) has a lining (2), and the inner surface of lining (2) is coated with a composite layer (3).
Compared with the prior art, the utility model has been set up a metal lining that has coat at the inner ring of fairlead, the coefficient of expansion that whole compound direction is overlapped is little, coefficient of friction is also little, prevent in the use incident pine or the catching phenomenon of cooperating between the fairlead and moving conductive rod effectively, optimized the design of fit tolerance.It is low to have cost of manufacture; Not changing under the vacuum interrupter existing structure situation, be easy to install and use; The characteristics that result of use is good.Can be used in the various vacuum interrupters of existing structure.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Accompanying drawing 1 is the structural representation of compound direction cover;
Accompanying drawing 2 is the view of installing and using of compound direction cover.
Embodiment: as shown in Figure 1, the compound direction cover is by fairlead 1 and the lining 2 that is embedded in its inner ring, and the composite layer 3 that lining 2 inner surfaces apply constitutes.Fairlead 1 can adopt nylon 6 or nylon 1010 to make, and also can adopt materials such as engineering plastics to make.Lining 2 can adopt the little material of the coefficient of expansion such as steel, copper.Coat can adopt the composite material that contains polytetrafluoroethylene, lead, bronze powder to apply and form, and coat both can prevent that metal lining 2 and moving conductive rod from gluing together, and had the little characteristics of coefficient of friction again.As shown in Figure 2, the installation site and the use of compound direction cover are the same with existing fairlead.Because it is little that metal lining 2 has a thermal coefficient of expansion, overcome the shortcoming of nylon fairlead.Coat then can prevent to occur between metal lining 2 and the moving conductive rod 3 phenomenon of gummed, has the little characteristics of coefficient of friction again.Therefore adopt the compound direction cover to replace existing fairlead, can optimize the design of fit tolerance, can in the use of vacuum interrupter, not occur cooperating pine or catching phenomenon between compound direction cover and the moving conductive rod 3.
Claims (1)
1, the compound direction cover used of vacuum interrupter, its formation comprises fairlead (1), it is characterized in that: the inner ring of fairlead (1) has a lining (2), and the inner surface of lining (2) is coated with a composite layer (3).
