Abstract

The utility model relates to an electric operation mechanism of a circuit breaker. The utility model is characterized in that a left electromagnet (3) and a right electromagnet (4) are arranged on the front side of a bottom plate (9) side by side. A left armature (10) and a right armature (12) are respectively arranged in the left electromagnet (3) and the right electromagnet (4). The outer ends of the left armature (10) and the right armature (12) are respectively movably connected with a rotary plate (7) through a left shaft pin (1) and a right shaft pin (5). The rotary plate (7) is connected with a transmission mechanism of the circuit breaker. The utility model can remotely control the circuit breaker to open, close and buckle again.

Description

The motor-operating mechanism of circuit breaker

The utility model relates to a kind of operating mechanism of circuit breaker.

In the prior art, the motor-operating mechanism of circuit breaker comprises base plate, is arranged at electromagnet on the base plate, two armature on same straight line in the electromagnet, and described armature drives the transmission mechanism of circuit breaker again.Because two armature on same straight line, are added the stroke of armature, so its length direction is long especially, have brought inconvenience to installation.

The purpose of this utility model is to provide a kind of motor-operating mechanism that makes the circuit breaker that length reduces.

The technical solution of the utility model is: the motor-operating mechanism of circuit breaker, the front of base plate is set side by side with left electromagnet and right electromagnet, be respectively equipped with left armature and right armature in described left electromagnet and the right electromagnet, by left pivot pin and right pivot pin and finger plate flexible connection, the transmission mechanism of described finger plate and circuit breaker links respectively in the outer end of described left armature and right armature.

The utility model compared with prior art has following advantage:

Owing to arrange about two armature are, make the utility model on width, suitably increase, but length greatly reduce, be applicable in regulator cubicle and install.The rotation friction of finger plate is little, makes the starting current of electromagnet diminish, and the requirement of electromagnet reduces and can reduce production costs.

The utility model will be further described below in conjunction with drawings and Examples:

Accompanying drawing 1 is a structural front view of the present utility model;

Accompanying drawing 2 is a left view of the present utility model; Wherein:

[1]. left pivot pin; [2]. left bar-shaped trough; [3]. left electromagnet; [4]. right electromagnet; [5]. right pivot pin; [6]. right bar-shaped trough; [7]. finger plate; [8]. handle; [9]. base plate; [10]. left armature; [11]. rotating shaft; [12]. right armature; [13]. connecting lever;

Embodiment: referring to accompanying drawing 1 and accompanying drawing 2, the motor-operating mechanism of circuit breaker is that the front of base plate [9] is set side by side with left electromagnet [3] and right electromagnet [4], be respectively equipped with left armature [10] and right armature [12] in described left electromagnet [3] and the right electromagnet [4], the outer end of described left armature [10] and right armature [12] flexibly connects with finger plate [7] by left pivot pin [1] and right pivot pin [5] respectively, and described finger plate [7] links with the transmission mechanism of circuit breaker.The left and right sides of described finger plate [7] is respectively equipped with left bar-shaped trough [2] and right bar-shaped trough [6], described left pivot pin [1] and right pivot pin [5] are inserted in respectively in described left bar-shaped trough [2] and the right bar-shaped trough [6], when finger plate [7] rotated, described left and right pivot pin slided in bar-shaped trough separately.Described left bar-shaped trough [2] and right bar-shaped trough [6] all are the bar-shaped troughs that extends to the direction of the center of rotation of finger plate [7].One side of the center of rotation of described finger plate [7] is connected with rotating shaft [11], the outside of described rotating shaft [11] is connected with and the perpendicular handle [8] of rotating shaft [11], can directly use hand actuating handle [8] when needed, finish combined floodgate, the separating brake of circuit breaker and pull work again.It is to be provided with connecting lever [13] at the back side of base plate [9] that the transmission mechanism of described finger plate [7] and circuit breaker links, described connecting lever [13] is connected with the rotating shaft of passing base plate [9] [11], when finger plate [7] rotates, drive connecting lever [13] and rotate, connecting lever [13] can drive circuit breaker again by striking gear and finish actuating.The utility model is to drive finger plate [7] by a pair of electromagnet to rotate, again the transmission by rotating shaft [11], connecting lever [13] to circuit breaker close a floodgate, separating brake and detain actuating again.When left electromagnet [3] adhesive left side armature [10], drive finger plate [7] by left pivot pin [1] and do the clockwise direction rotation, thereby to the circuit breaker actuating of closing a floodgate; When the right armature of right electromagnet [4] adhesive [12], drive finger plate [7] and do rotation counterclockwise, thereby circuit breaker is carried out separating brake and detains actuating again.
