Abstract
The utility model relates to a three-position electric indicating device of a drawout breaker. The three-position electric indicating device comprises an electric indicating device bracket consisting of a sliding plate, a small sliding plate and a big side plate, wherein the small sliding plate and the big side plate are provided with chutes; a semicylindrical sliding block is connected with the sliding plate through bolts; the semicylindrical sliding block can be slide in the chutes arranged on the small sliding plate and the big side plate; three microswitches which are used for indicting three position signals, namely, connection, test and separation are arranged in the electric indicating device bracket, wherein a rolling wheel, a transmission link, a spring plate and a signal transmission joint are arranged on each microswitch; when the sliding plate is driven by external force, the semicylindrical sliding block can slide in the chutes; and when the semicylindrical sliding block slide to the rolling wheel on the microswitch at the corresponding indication position, the rolling wheels can drive the transmission links, so that the signal transmission joints form a loop and emit electric signals, and thus the position state of the breaker can be mastered remotely by a central control room.
Description
Technical field:
The utility model relates to the electric indicating device of " connection ", " test " in a kind of pull-out type low-voltage circuit breaker, " separation " three service positions, belongs to low-voltage electrical apparatus manufacturing technology field.
Background technology:
The pull-out type low-voltage circuit breaker has " connection ", " test ", " separation " three service positions usually.When being in " connection " position, major loop and secondary circuit are all connected, and normal operation of circuit breaker provides the instant messages of system to the user; Major loop breaks off when being in " test " position, and only secondary circuit is connected, and the user can carry out some necessary test and detections to circuit breaker; When being in " separation " position, major loop and secondary circuit all break off, and the user can operate and change the body of circuit breaker.
At present; The indication of traditional three service positions of pull-out type low-voltage circuit breaker; The rotation of mechanical type guide rod that can only be through circuit breaker itself realizes indication; Observation scope only is confined to the scene, and can not let central control room grasp the residing state of circuit breaker at a distance, thereby makes the development trend of circuit breaker " networking ", " communication type " receive very big restriction.
Summary of the invention:
Problem in view of above-mentioned existence; The purpose of the utility model provides a kind of simple in structure, easily manufactured, signal and transmits the electric indicating device in safe and reliable drawout breaker three positions, to satisfy three remotely-indicated needs in service position of drawout breaker.
The electric indicating device in three positions of the described a kind of drawout breaker of the utility model; Include one and form electric indicating device support through bolt by slide plate, small slide plate, big side plate; On small slide plate, big side plate; Be provided with chute, the semicolumn slide block is connected with slide plate through screw, and the semicolumn slide block can be along sliding in the chute that is arranged on small slide plate and the big side plate; In electric indicating device support, be provided with three sensitive switches that are used for indication " connection ", " test ", " separation " three position signallings, on every sensitive switch, be provided with roller, drive kinematic link, spring leaf and signal transfer connector.
As preferably, the roller on described every sensitive switch is installed in the end of spring leaf.
As preferably, described driving kinematic link is arranged at the below of spring leaf, and is shape high up in the air.
When external force drove slide plate, the semicolumn slide block can slide in chute; During roller on the sensitive switch when the semicolumn slide block slides into the corresponding index position; Roller can drive kinematic link, makes the signal transfer connector constitute a loop, and sends the signal of telecommunication; Like this, can let central control room grasp the residing location status of circuit breaker at a distance.

Embodiment:
Below in conjunction with accompanying drawing the utility model is done further detailed explanation, but be not restriction the protection range of the utility model.
As illustrated in fig. 1 and 2; The electric indicating device in three positions of the described a kind of drawout breaker of the utility model; Include one and form electric indicating device support through bolt, on small slide plate 2, big side plate 5, be provided with chute 17 by slide plate 1, small slide plate 2, big side plate 5; Semicolumn slide block 7 is connected with slide plate 1 through screw 4, and semicolumn slide block 7 can be along sliding in the chute 17 that is arranged on small slide plate 1 and the big side plate 5; In electric indicating device support, be provided with 3,18,19, three sensitive switches of three sensitive switches that are used for indication " connection ", " test ", " separation " three position signallings and be installed on the little side plate 2 through bolt 12, nut 13 and pad 14 respectively.On every sensitive switch, be provided with roller 8, drive kinematic link 9, spring leaf 15 and signal transfer connector 10,11; Roller 8 on every sensitive switch is installed in the end of spring leaf 15, drives kinematic link 9 and is arranged at the below of spring leaf 15, and be shape high up in the air; Be provided with draw-in groove 16 in the end of slide plate 1, draw-in groove 16 is connected with the breaker body switch through bindiny mechanism.In addition, on big side plate 5, be provided with installing hole 6.
The working method of the utility model realizes like this: when circuit breaker withdrawed from and advance, the breaker body switch drove the semicolumn slide block 7 that links to each other with slide plate 1 through the draw-in groove 16 that is arranged at slide plate 1 end, and it is slided in chute 17.When semicolumn slide block 7 slides into a certain position in chute 17; Roller 8 on the semicolumn slide block 7 compressing sensitive switches 3; The elastic force that roller 8 overcomes spring leaf 15 moves downward; Compressing kinematic link 9 impels signal transfer connector 10,11 to connect, thereby constitutes a loop, and the connection through lead promptly can transmit the contact signal of breaker body service position of living at a distance.After semicolumn slide block 7 moved past certain distance, roller 8 rose, and spring leaf 15 breaks away from kinematic link 9, thereby signal transfer connector 10,11 breaks off, and interrupt in the loop, and then contactless signal is seen off.
In like manner; When semicolumn slide block 7 slides into another position in chute 17, semicolumn slide block 7 compressing sensitive switches 18 or 19 o'clock, the roller 8 on the sensitive switch 18 or 19; The elastic force that roller 8 overcomes spring leaf 15 moves downward; Compressing kinematic link 9 impels signal transfer connector 10,11 to connect, and constitutes a loop, and the connection through lead promptly can transmit the contact signal of breaker body service position of living at a distance.Can make three groups of loops difference break-makes in 3 sensitive switches through above-mentioned working method, make drawout breaker be transferred to central control room respectively, realize remote observation at the contact signal of " connection ", " test ", " separation " three service positions.
