Abstract
The utility model discloses a mechanism interlocking device of a high voltage circuit breaker, which comprises a substrate, an interlocking turn arm and a lever plate and is characterized by also comprising a connecting plate and a steel plate. The interlocking turn arm and the lever plate are respectively fixed on the substrate through a rotary shaft, one end of the connecting plate is pivoted toone end of the lever plate, the other end of the connecting plate is connected with the steel plate, and one end of the interlocking turn arm presses on one end of the lever plate. When the interlocking turn arm rotates clockwise, the utility model presses the lever plate, drives the connecting plate, enables the connecting plate to move upwards, adopts a steel rope to pull a circuit breaker tripping device to enable the circuit breaker to trip, and can carry out safety inspection; when the interlocking turn arm rotates anticlockwise, the utility model releases the lever plate, the lever plate automatically resets, and the circuit breaker can operate in a closing way.
Description
Technical field
The utility model relates to a kind of interlock, particularly relates to a kind of the use firmly through the transformation back and connects, and can reliably realize the high-voltage breaker mechanism interlock of the urgent sub-switching operation of circuit breaker.
Background technology
At present in circuit breaker operation mechanism in the urgent switching-off device, common urgent switching-off device is that steel wire rope type promptly is soft connection, can not reliably realize the urgent sub-switching operation of circuit breaker, adjust difficulty, be badly in need of a kind of simple in structure, the convenient manufacturing and installation do not need to adjust, and can reliably realize the urgent switching-off device of separating brake.
Summary of the invention
At the problems referred to above, main purpose of the present utility model is to provide a kind of high-voltage breaker mechanism interlock that soft connection on the original circuit breaker is changed into the steel plate interconnection system, the utility model solves above-mentioned technical problem by following technical proposals: a kind of high-voltage breaker mechanism interlock, it comprises substrate, the interlocking connecting lever, lever plate, it is characterized in that: described interlock also comprises connecting plate and steel plate, described interlocking connecting lever and lever plate are fixed on the substrate by rotating shaft respectively, described connecting plate one end is articulated in an end of lever plate, the other end connects described steel plate, and an end of described interlocking connecting lever is pressed in an end of lever plate.
The utility model is with the steel wire rope type of former circuit breaker---soft connection, be replaced by and use the steel plate interconnection system---rigid connection, by installing lever plate and connecting plate additional, realize reliable control separating brake, through improved hard connection, can reliably realize the urgent sub-switching operation of circuit breaker.Simple in structure, the convenient manufacturing and installation do not need to adjust.
Wherein, the other end of described steel plate connection circuit breaker takes off a mouthful device.
Wherein, described lever plate is divided into left and right sides two boards, and left and right sides two boards is " eight " font, and left and right sides two boards is fixed by being fixed on the substrate rotating shaft.
Wherein, described interlocking connecting lever is divided into the turn left arm and the arm of turning right, and the turn left arm and the arm of turning right are fixed by being fixed on the substrate rotating shaft, and the described brachium of turning left is in the arm of turning right.
Positive progressive effect of the present utility model is: the utility model is with the steel wire rope type of former circuit breaker---soft connection, be replaced by and use the steel plate interconnection system---rigid connection, by installing lever plate and connecting plate additional, realize reliable control separating brake, through improved hard connection, can reliably realize the urgent sub-switching operation of circuit breaker.Simple in structure, the convenient manufacturing and installation do not need to adjust.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.Fig. 1 is a structural representation of the present utility model, the utility model comprises substrate 1, interlocking connecting lever 2, lever plate 3, connecting plate 4 and steel plate 5, interlocking connecting lever 2 and lever plate 3 are fixed on the substrate 1 by rotating shaft respectively, and connecting plate 4 one ends are articulated in an end of lever plate 3, the other end connects steel plate 5, and an end of interlocking connecting lever 2 is pressed in an end of lever plate 3.The other end of steel plate 5 connects circuit breaker and takes off mouthful device 6.Lever plate 3 is divided into left and right sides two boards, and left and right sides two boards is " eight " font, and left and right sides two boards is fixed by being fixed on the substrate 1 rotating shaft.Interlocking connecting lever 2 is divided into the turn left arm and the arm of turning right, and the turn left arm and the arm of turning right are fixed by being fixed on the substrate 1 rotating shaft, and the brachium of turning left is in the arm of turning right.
When interlocking connecting lever 2 clockwise rotates, press regulations and parameters plate 3, drive connecting plate 4, connecting plate 4 is moved up, the pulling circuit breaker takes off mouthful device 6 makes circuit breaker take off mouth, can carry out safety inspection.
When interlocking connecting lever 2 when rotating counterclockwise, trip lever plate 3, lever plate 3 automatically resets, the circuit breaker operation of just can closing a floodgate.
The utility model is with the steel wire rope type of former circuit breaker---soft connection, be replaced by and use the steel plate interconnection system---rigid connection, by installing lever plate and connecting plate additional, realize reliable control separating brake, through improved hard connection, can reliably realize the urgent sub-switching operation of circuit breaker.Simple in structure, the convenient manufacturing and installation do not need to adjust.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
