Abstract
The utility model relates to an arm touching sleeve pipe and belongs to the technical field of power supply equipment. The arm touching sleeve pipe comprises a sleeve pipe main body, wherein two ends of the sleeve pipe main body firstly and respectively extend outwards to form ring edgefolds along the radial direction and then extend outwards to form cylindrical edgefolds along the axial direction in order to form a wire outlet side protecting end and a moving contact protecting end which are respectively arranged on the two sides of the sleeve pipe main body, and the wire outlet side protecting end and the moving contact protecting end are integrated with the sleeve pipe main body. The arm touching sleeve pipe has the advantages that all components of the arm touching sleeve pipe are molded integrally, the arm touching sleeve pipe is simple in structure and convenient to assemble, reduces assembly cost, and improves assembly efficiency, and greatly improves reliability and economy of a high voltage alternating current vacuum circuit interrupter based on that the high voltage alternating current vacuum circuit interrupter is in phase to phase insulation and ground insulation.
Description
Technical field
The utility model relates to a kind of contact arm sleeve pipe, is particularly useful for the vacuum circuit-breaker that electric pressure is 40.5kV, belongs to the power supply unit technical field.
Background technology
Understand according to the applicant, electric pressure is that the vacuum circuit-breaker of 40.5KV comprises circuit breaker operation mechanism, pole or insulating cylinder, insulated tension pole, conduction contact arm, contact arm insulating case and plum blossom moving contact, the contact arm that wherein the conducts electricity important accessory that is absolutely necessary.Because vacuum circuit-breaker need reach the requirement of insulation against ground and phase insulation, so the conduction contact arm must be used with the contact arm insulating case.At present; 40.5KV vacuum circuit-breaker conduction contact arm generally adopts heat-shrinkable T bush and former and later two insulating shields to reach the contact arm insulation effect in the industry; Need use special-purpose baking rifle that heat-shrinkable T bush is heated pyknosis on contact arm during assembling, but this mode exists cost high, part is too much; Assembly technology requires high, the problem that efficiency of assembling is low.
The utility model content
The purpose of the utility model is: to the problem of above-mentioned prior art existence; Propose a kind of simple in structure; The contact arm sleeve pipe of being convenient to assemble on the basis that guarantees vacuum circuit-breaker phase insulation and insulation against ground, improves the reliability of HVAC vacuum circuit breaker and economy greatly.
In order to reach above purpose, the technical scheme of the utility model is following: a kind of contact arm sleeve pipe comprises casing main body; It is characterized in that; The two ends of said casing main body extend radially outward out earlier circular fold respectively, extend outward the tubular flanging vertically again, form to lay respectively at said casing main body two ends and protect end with said casing main body integrated outlet side protection end and moving contact.
Each parts of the utility model are one-body molded, and are simple in structure, easy to assembly, can reduce assembly cost and improve efficiency of assembling, are applicable to employed pole of HVAC vacuum circuit breaker or insulating cylinder structure; End can once the outlet port and the moving contact of part main body cover fully with circuit breaker respectively for outlet side protection end and moving contact protection; The electrified body and the outside of vacuum circuit-breaker are isolated fully; Both strengthen the insulation effect of vacuum circuit-breaker self, increased electrified body alternate and over the ground air clear distance and creepage distance again.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Embodiment
The contact arm sleeve pipe basic structure of present embodiment is as shown in Figure 1; Comprise casing main body 2; The two ends of casing main body 2 extend radially outward out earlier circular fold respectively, extend outward the tubular flanging vertically again, form to lay respectively at casing main body 2 two ends and hold 3 with casing main body 2 integrated outlet side protection ends 1 and moving contact protection.
All with round-corner transition, can effectively prevent to produce in the part cooperation place insulating properties of defective effect circuit breakers such as bubble between casing main body 2 and the circular fold and between circular fold and the tubular flanging because of rigging error.
During assembling; The contact arm that only needs conduct electricity is sleeved in the casing main body 2 and makes the moving contact protection hold 3 moving contact covered fully; Again outlet side protection end 1 is assemblied in the leading-out terminal place of insulating cylinder or pole; Then the plum blossom moving contact is assemblied on the contact arm, at last each parts of circuit breaker is installed fastening putting in place and get final product.
Outlet side protection end 1 and moving contact protection end 2 can be respectively with circuit breaker once the outlet port and the moving contact of part main body cover fully, the electrified body of vacuum circuit-breaker and outside are isolated fully.
Except that the foregoing description, the utility model can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection range of the utility model requirement.
Claims (2)
1. a contact arm sleeve pipe comprises casing main body; It is characterized in that; The two ends of said casing main body extend radially outward out earlier circular fold respectively, extend outward the tubular flanging vertically again, form to lay respectively at said casing main body two ends and protect end with said casing main body integrated outlet side protection end and moving contact.
2. contact arm sleeve pipe according to claim 1 is characterized in that, between said casing main body and the circular fold and between said circular fold and the tubular flanging all with round-corner transition.
