Abstract
The utility model relates to an integrated connecting terminal device for a radiator. The integrated connecting terminal device is used for a high-current vacuum generator circuit breaker. Radiating fins are arranged on the outer periphery of a connecting terminal, and form an integrated structure. The connecting terminal is connected with the fixed end of a vacuum extinction chamber through screw through holes. A fixed-end arcing contact conductive contact finger and a fixed-end arcing contact spring are arranged on the connecting terminal through a through hole I and a through hole II respectively. The through hole I is sleeved in the through hole II. An integrated radiation and current conduction structure is implemented, heat conduction and current conduction channels are simplified, and the thermal resistance of the whole heat transfer path is effectively reduced; and moreover, the device is simple in structure and easy to cast and machine.
Description
Technical field
The utility model relates to a kind of radiator and connection terminal structure, relates in particular to the radiator integral type connecting terminal apparatus that a kind of big current vacuum generator outlet circuit breaker is used.
Background technology
As everyone knows, the heat that loop resistance produces in the vacuum circuit-breaker is the main thermal source that influences temperature rise.When rated current when 1600A is following, the vacuum interrupter loop resistance will account for about 50% ~ 60% of high-pressure vacuum breaker loop resistance usually; When rated current at 1600A and when above, the loop resistance of vacuum interrupter will account for about 70%～80% of whole circuit breaker loop resistance usually.Because contact gap contact resistance is the chief component of vacuum interrupter loop resistance, and that contact system is sealed in vacuum extinction is indoor, and the heat of its generation can only dispel the heat to the outside through dynamic and static conducting rod.For the big current vacuum generator outlet circuit breaker of the 10000A rated current that the present invention relates to; Though adopted the two contact vacuum interrupters of the big electric current of the patent No.: ZL200710012389.1; Fundamentally reduce the loop resistance of vacuum circuit-breaker through the method that changes the vacuum arc-extinguishing chamber contact structure, reduced its caloric value.But, in order to satisfy the design concept of " passive cooled ", must optimal design radiator and connecting terminal block thereof, adopt on this basis that the mode of natural cooling is common to solve big rated current problem of temperature rise.
Summary of the invention
The utility model provides a kind of radiator integral type connecting terminal apparatus to the problem that exists in the above-mentioned prior art, has solved the big problem of heat-transfer path thermal resistance in the prior art, and simple in structure, is easy to processing.
The technical scheme of the utility model is following:
The neighboring of binding post is provided with groups of fins and is integral the formula structure; Binding post links to each other with the quiet end of vacuum interrupter through screw through-hole; Quiet end arcing contact conduction fingertip and quiet end arcing contact touch spring are arranged on the binding post through through hole I and through hole II respectively, and through hole I is sleeved in the through hole II.
The quiet end end face of described binding post lower surface and vacuum interrupter is equipped with silver coating.
Described touch spring is spacing through cover plate.
Described fin is the straight rib fin of rectangle.
