Abstract
The utility model relates to an interlocking device preventing misoperation of a breaker handcart. The interlocking device comprises a twist handle (1) with a function of locking a breaker, a rocker arm (2), a transverse slide plate (3), a vertical push rod (4), and an electromagnetic blocking device (5) with a function of sensing a breaker using condition. The twist handle (1) and the rocker arm (2) are hinged. The rocker arm (2) is connected with the slide plate (3) through a pin roll (6) in a transmission manner. The slide plate (3) is provided with a slope (8) which is helpful to jack up the push rod (4). A bottom end of the push rod (4) is provided with an idler wheel (7) so as to facilitate the push rod (4) slide on the slide plate (3). A top end of the push rod (4) is connected with internal mechanisms of the breaker. The interlocking device preventing misoperation of a breaker handcart can effectively prevent misoperation of the breaker handcart. The device has a self-locking protection function, and is reasonable in design, simple in structure, easy in operation, and is safe and reliable.
Description
Technical field
The utility model relates to the power engineering field, is a kind of interlock that prevents the circuit breaker cart misoperation specifically.
Background technology
In recent years, along with expanding economy, the China Power industrial expansion impetus is very swift and violent, and primary cut-out is as one of main element of high voltage switchgear, and the performance of primary cut-out is proposed more and more higher requirement.Handcart type breaker mainly is divided into middle and two kinds of structures of console mode at present; the relative console mode structure of middle structure; more compact structure, design are more reasonable, manufacture and also more easily to realize industrialization, scale, and the console mode structure also has its safe advantage.Switch performance descends early stage a lot of floor type handcart circuit breaker along with service life is long, and insulation has also begun to wear out, is faced with large-scale rectification.There is following problem in the at present rectification of floor type handcart circuit breaker: the one, old circuit breaker spare and accessory parts production procurement difficulty, some in addition stop production;
The 2nd, along with the continuous application of new technology, new technology, old breaker structure design, security performance are not as present newly-designed circuit breaker.
Summary of the invention
The purpose of this utility model is to provide a kind of interlock that prevents the circuit breaker cart misoperation, and this interlock that prevents the circuit breaker cart misoperation can effectively prevent the misoperation of circuit breaker hand, has the self-lock protection function; and reasonable in design; simple in structure, easily operation is safe and reliable.
The technical solution of the utility model is: a kind of interlock that prevents the circuit breaker cart misoperation, comprise the rotary handle (1) with locking circuit breaker function; rocking arm (2); horizontal slide plate (3); vertical push rod (4) and have the electromagnetic locking device (5) that the perception circuit breaker uses status function; described rotary handle (1) is hinged with rocking arm (2); described rocking arm (2) is in transmission connection by bearing pin (6) and slide plate (3); described slide plate (3) is provided with the slope (8) that is beneficial to jack-up push rod (4); described push rod (4) bottom is provided with roller (7) and is beneficial to push rod (4) in slide plate (3) slip, and described push rod (4) top is connected with the circuit breaker internal mechanism.
The utility model has the advantage of: the one, this prevents that the interlock of circuit breaker cart misoperation has the self-lock protection function, can effectively prevent the misoperation of circuit breaker hand; The 2nd, this device only is provided with rotary handle, rocking arm, slide plate, push rod and electromagnetic locking device, and is simple in structure, reasonable in design, easily makes; The 3rd, this device only needs the operation rotary handle just can realize the obstacle accident that the handcart misoperation causes, easily operation is safe and reliable.

Embodiment
For above-mentioned feature and advantage of the present utility model can be become apparent, embodiment cited below particularly, and cooperation accompanying drawing be described in detail below, but the utility model are not limited to this.
With reference to legend 1 ~ 3, a kind of interlock that prevents the circuit breaker cart misoperation, comprise the rotary handle (1) with locking circuit breaker function; rocking arm (2); horizontal slide plate (3); vertical push rod (4) and have the electromagnetic locking device (5) that the perception circuit breaker uses status function; described rotary handle (1) is hinged with rocking arm (2); described rocking arm (2) is in transmission connection by bearing pin (6) and slide plate (3); described slide plate (3) is provided with the slope (8) that is beneficial to jack-up push rod (4); described push rod (4) bottom is provided with roller (7) and is beneficial to push rod (4) in slide plate (3) slip, and described push rod (4) top is connected with the circuit breaker internal mechanism.This interlock that prevents the circuit breaker cart misoperation can effectively prevent the misoperation of circuit breaker hand, has the self-lock protection function, and reasonable in design, simple in structure, and easily operation is safe and reliable.
Work operation instruction of the present utility model: this device is installed in the console mode vehicle frame inner, again the middle truck circuit breaker is fallen to being contained on the console mode vehicle frame, the top of push rod (4) directly is connected with breaker mechanism is inner with the hole of dodging of middle truck circuit breaker by the console mode vehicle frame.When circuit breaker is in gate-dividing state, rotary handle (1) and expose the handcart rocking arm turns right, driving simultaneously rocking arm (2) swings; rocking arm (2) connects by bearing pin (6) and drives slide plate (3) horizontal slip; the slope (8) on the slide plate (3) acts on the roller (7) on the push rod (4); make push rod (4) upward sliding; the top of push rod (4) is connected by bolt and circuit breaker are inner simultaneously; breaker mechanism is moved; the closing function of locking circuit breaker, handcart can shake at this moment; Backward rotation rotary handle (1) is the closing function of release circuit breaker then.When circuit breaker was in "on" position, electromagnetic locking device (5) will stop slide plate (3) horizontal slip, thereby handle (1) is rotated, and caused and can't expose the handcart rocking arm, and circuit breaker cart can't shake.
The above only is preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
