Abstract
The utility model relates to a sliding contact for an indoor high voltage vacuum circuit breaker. Each sliding contact is composed of nine conducting strips (3) with the completely identical shape and circularly arranged by layers according to different working current. The conducting strip of each layer is provided with a pressure spring (4) the elastic force of which is utilized to cause two contact surfaces of the conducting strips to be respectively and reliably contacted with a movable conductive rod (1) and a lower bracket (5). Because a sliding connection form is adopted, the elastic force action of the springs between the conducting strips causes the contact surfaces of the conducting strips to be always contacted with the movable conductive rods and the brackets reliably. The utility model has the advantages of reasonable structure and good heat dispersion performance.
Description
The utility model relates to a kind of sliding contact of indoor high-voltage vacuum circuit breaker, belong to the technical field of high voltage switchgear.
When handling being connected between arc control device moved end conducting rod and support, generally adopt the form that is flexible coupling in the existing indoor high-voltage vacuum circuit breaker, all exist deficiency at aspects such as layout, heat radiations and be flexible coupling.
The purpose of this utility model is the defective at above-mentioned existence, proposes the be slidingly connected sliding contact of indoor high-voltage vacuum circuit breaker of form of a kind of employing.
Technical solution of the present utility model:
Sliding contact is provided in a side of and conducts electricity between line bracket and vacuum interrupter moved end conducting rod, the effect that is slidingly connected of initial line contact.Each sliding contact is made up of nine identical conductive vanes of shape (3), according to the operating current difference, the rounded layout of layering, stage clip (4) is housed between the conductive vanes of each layer, utilizes the elastic force of stage clip that two contact-making surfaces of conductive vanes are contacted with lower carriage (5) reliably with moving conductive rod (1) respectively.
The shape of its conductive vanes is foliaceous, and the contact-making surface of itself and support (5) is circular-arc, and with the contact-making surface of conducting rod (1) be plane.
The arrangement rotation direction of upper and lower two-layer conductive vanes is opposite.
Advantage of the present utility model is rational in infrastructure, perfect heat-dissipating, and contact is reliable.
Accompanying drawing 1,2 is respectively that master of the present utility model looks, the plan structure schematic diagram.
Further describe the operation principle of the present utility model and the course of work thereof below in conjunction with accompanying drawing:
Vacuum interrupter moved end conducting rod is made upper and lower approximate straight line motion in the operating process of circuit breaker on/off switch, in its course of action, need to guarantee reliably electrically contacting between conducting rod and support, the sliding contact of being made up of conductive vanes promptly plays this effect, under the effect of spring force, two contact-making surfaces arranging conglobate conductive vanes will keep well contacting with conducting rod and lower carriage respectively reliably, when even slight inclination and wearing and tearing take place in conducting rod at the volley, under the spontaneous regulating action of spring force, still can keep reliably electrically contacting.
