Abstract
The invention discloses a novel horizontal circuit breaker with permanent magnet mechanisms. The novel horizontal circuit breaker comprises a side plate, a frame made of bakelite parts and a yoke; the two permanent magnet mechanisms are symmetrically distributed on the yoke, a separating brake spring is arranged in the center of the yoke, each permanent magnet mechanism comprises an upper iron core push rod and a lower iron core push rod, the two upper iron core push rods are respectively connected to one ends of two rocker arms, the other end of the separating brake spring is connected onto the two rocker arms, and the other ends of the two rocker arms are rotationally fixed onto a square shaft; and a plurality of switch tubes are arranged in the frame made of the bakelite parts, a contact pressure spring is mounted between a crank arm and a movable contact of each switch tube, the front end of the crank arm is respectively clamped on various movable-end draw bars, the other end of each movable-end draw bar perpendicularly drives the corresponding switch tube, and the rear end of the crank arm is connected with the square shaft. The novel horizontal circuit breaker has the advantages that the integral height and the integral size of the novel horizontal circuit breaker are reduced by nearly a half as compared with those of a like product, and the novel horizontal circuit breaker is simple and compact in structure and reliable in performance as compared with the like product. The novel horizontal circuit breaker can be widely applied to feeding systems with explosion-proof shells for coal mines.
Description
Technical field:
The present invention relates to field of circuit breakers, being provided with of being specifically related to use in high, medium and low voltage breaker, contactor in a kind of coal mine explosion-proof feed system realized the novel horizontal permanent magnet mechanism circuit-breaker of driven in synchronism switching tube by connecting lever by two permanent magnet mechanisms.
Technical background:
In the coal mine explosion-proof feed system, low pressure 630A circuit breaker volume is large and heavy at present, and the volume of corresponding explosion-proof casing is larger, heavier.Large and the heaviness of volume not only makes the switch cost increase, and also is not easy to transportation in the down-hole; All ubiquity is not enough for present like product functional reliability, stability in addition.
Summary of the invention:
The objective of the invention is to solve the problem that prior art exists, a kind of applied widely, simple in structure, volume-diminished nearly half and dependable performance, cheap novel horizontal permanent magnet mechanism circuit-breaker are provided.
The present invention is achieved by the following technical solutions:
a kind of novel horizontal permanent magnet mechanism circuit-breaker, include side plate, it is characterized in that: also include the bakelite spare framework that is positioned at the side plate front portion, be positioned at the yoke at side plate rear portion, be symmetrically distributed with two permanent magnet mechanisms on yoke, a tripping spring is equipped with at the center of yoke, with as separating brake reaction force used, permanent magnet mechanism includes the iron core upper push-rod, screw rod under iron core, the iron core upper push-rod of described two permanent magnet mechanisms is connected to an end of two rocking arms, the other end of tripping spring is connected on two rocking arms, the other end of two rocking arms rotates and is fixed on square shaft, be provided with a plurality of switching tubes, a plurality of contact stage clip, a plurality of moved ends pull bar, a connecting lever in described bakelite spare framework, be separately installed with a contact stage clip between the moving contact of connecting lever and each switching tube, the front end of connecting lever has a plurality of U-shaped breach, each U-shaped breach is stuck on a moved end pull bar, the other end of each moved end pull bar is switching tube of vertical drive respectively, and the rear end of connecting lever is connected with square shaft.
Described a kind of novel horizontal permanent magnet mechanism circuit-breaker is characterized in that: described iron core upper push-rod is fixed on an end of rocking arm by bearing pin.
Described a kind of novel horizontal permanent magnet mechanism circuit-breaker is characterized in that: on described connecting lever, the number of the number of the number of the number of breach, switching tube, contact stage clip, moved end pull bar is three.
On/off switch motion principle of the present invention is:
When the permanent magnetism coil of two permanent magnet mechanisms (is that positive pole connects first winding head by forward dc voltage, second wiring circle tail of negative pole, two coil series connection) time, two iron core upper push-rods drive rocking arm and move backward, two rocking arms pull connecting lever to move upward take square shaft as the motion axle center, the make progress moving contact of pull switch pipe of three moved end pull bars on connecting lever, thereby make the switching tube conducting, namely complete making process one time; In like manner, when the permanent magnetism coil of two permanent magnet mechanisms (is that negative pole connects first winding head by direct reverse voltage, anodal second wiring circle tail, the series connection of two coils) or during under-voltage, outage, under the common reaction force of tripping spring and three contact stage clips, two iron core upper push-rods drive rocking arm and travel forward, two rocking arms are take square shaft as the motion axle center, pull connecting lever to move downward, three moved end pull bars on connecting lever pull the moving contact of switching tube downwards, thereby switching tube is disconnected, namely complete the separating brake process one time.
Advantage of the present invention is:
Whole height of the present invention and volume ratio like product dwindled near half, and structure is simple, compact than like product, performance is more reliable, can be widely used in the feed system of colliery with explosion-resistant enclosure.
