Abstract
The utility model discloses an outdoor high-voltage alternating-current porcelain column type circuit breaker, which adopts a multi-pole dual-fracture structure. The multi-pole dual-fracture structure comprises three single poles, and each single pole comprises an arc extinguishing chamber, a closing resistor, a shunt capacitor, a pillar and an actuating mechanism; and the pillar is arranged on a rotary sealing structure, the arc extinguishing chamber is arranged on the pillar, and the rotary sealing structure is connected with a mechanism. Since the conventional direct-acting dynamic sealing structure is changed into the rotary sealing structure and the arc extinguishing chamber adopts the dual-acting dual-fracture structure, the reliability of the product and the switching performance of the product can be improved greatly, and the cost can be reduced greatly.
Description
Technical field:
The utility model belongs to the high voltage electric power equip ment field, relates to a kind of circuit breaker, especially a kind of outdoor high-voltage alternating current porcelain knob breaker.
Background technology:
Along with developing rapidly of State Grid's energy market, 550 kilovoltage grade circuit breaker costs constantly reduce, and high-effect arc control device continue to bring out.This product adopts two moving arc quenching chamber structures, reduces the action required merit greatly, thereby can join the lower mechanism of operating work.Break performance is improved on the basis that reduces product cost, so this product has boundless application prospect.
The utility model content:
To the problem of present like product existence, in order to satisfy with this synergy requirement, at existing product LW15A-550/Y4000-63 outdoor high-voltage alternating current porcelain knob SF
6On the basis of circuit breaker; Adapted is with CTY-I (X) the large power spring operation mechanism replaced C YA4 hydraulic pressure spring operating mechanism of my the up-to-date development of company; Change former straight moving movable sealing structure into rotational sealing structure, arc control device adopt two moving double break mouth structures, and reliability of products improves greatly; Break performance is greatly improved, and cost reduces greatly.
The purpose of the utility model is to overcome the shortcoming of above-mentioned prior art; A kind of outdoor high-voltage alternating current porcelain knob breaker is provided; This circuit breaker is a split pole double break mouth structure; Split pole double break mouth structure is made up of three one poles, and each one pole comprises arc control device, switching-on resistance, shunt capacitor, pillar and operating mechanism; Be provided with pillar above the said rotational sealing structure, be provided with arc control device above the pillar, this rotational sealing structure is connected with mechanism.Shift fork slide block mechanism, quiet side moving contact, pull bar and moving side contact are set in the said arc control device; Said quiet side moving contact and moving side contact are oppositely arranged, and quiet side moving contact top is provided with the shift fork slide block mechanism, and quiet side moving contact bottom is provided with pull bar.Be connected with interior connecting lever on the said pull bar, interior connecting lever is connected with outer connecting lever through axle.
LW mouth-550/T4000-63 the high-voltage AC breaker of the utility model is a split pole double break mouth structure, and every product is made up of three one poles, and each one pole comprises arc control device, switching-on resistance, shunt capacitor, pillar and operating mechanism.A product CTY-I of every utmost point adapted (X) large power spring operation mechanism, monopolar operation, three-phase is electric-linked.The high-voltage AC breaker of the utility model changes former straight moving movable sealing structure into rotational sealing structure, and arc control device adopt two moving double break mouth structures, and reliability of products improves greatly, and break performance is greatly improved, and cost reduces greatly.

Embodiment:
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Referring to Fig. 1-3, a kind of outdoor high-voltage alternating current porcelain knob breaker, this circuit breaker are split pole double break mouth structure, and split pole double break mouth structure is made up of three one poles, and each one pole comprises arc control device, switching-on resistance, shunt capacitor, pillar and operating mechanism; Be provided with pillar above the said rotational sealing structure, be provided with arc control device above the pillar, this rotational sealing structure is connected with mechanism.Shift fork slide block mechanism, quiet side moving contact, pull bar and moving side contact are set in the said arc control device; Said quiet side moving contact and moving side contact are oppositely arranged, and quiet side moving contact top is provided with the shift fork slide block mechanism, and quiet side moving contact bottom is provided with pull bar.Be connected with interior connecting lever on the said pull bar, interior connecting lever is connected with outer connecting lever through axle.
Mechanism makes the motion of horizontal direction change the motion of vertical direction into through the connecting lever in the pull bar pulling rotational structure; Then through the insulated tension pole in the interior connecting lever pulling pillar; And then change horizontal movement into moving both vertically through the steering structure in the arc control device, pass to two fractures to power respectively.
When arc control device closed a floodgate: the motion earlier of moving side passed to group slide block mechanism to power through pull bar then and exerts all one's strength oppositely, dials slide block mechanism and is connected with quiet side moving contact, thereby thereby make quiet side moving contact and moving side contact move toward one another reach the combined floodgate purpose.
During the arc control device separating brake: moving side passes to group slide block mechanism to power through pull bar and exerts all one's strength oppositely, dials slide block mechanism and is connected with quiet side moving contact, thereby make quiet side moving contact and moving side counter motion, and moving at last side separating brake puts in place, thereby reaches the separating brake purpose.
Operating mechanism promotes outer connecting lever, connecting lever in outer connecting lever rotates through axle, and interior connecting lever promotes insulated tension pole.
Above content is to combine concrete preferred implementation to further explain that the present invention did; Can not assert that embodiment of the present invention only limits to this; Those of ordinary skill for technical field under the present invention; Under the prerequisite that does not break away from the present invention's design, can also make some simple deduction or replace, all should be regarded as belonging to the present invention and confirm scope of patent protection by claims of being submitted to.
