Abstract
The utility model relates to a locking device for a closing mechanism of a breaker, which comprises an installing plate, a travel switch, a cover plate and a manual energy-storing shaft of the breaker, wherein a manual energy-storing draw rod of the breaker is arranged at the back side of the installing plate; the cover plate is arranged on the installing plate; the travel switch is arranged at the left side of an upper cover plate of the installing plate; the locking device also comprises a program lock, a hasp, a closing button and a closing half shaft; the program lock is arranged at the right side of the upper cover plate of the installing plate; a closing interlocking plate is arranged at the right side of the program lock; one end of the hasp is connected with the left end of the cover plate; the other end of the hasp is connected with a hasp plate at the upper end of the closing half shaft; and the middle part of the hasp is hinged with a connecting shaft. The utility model has simple structure and is convenient to install and use, and realizes mechanical and electrical locking of the closing mechanism of the breaker simultaneously.
Description
Technical field
The utility model relates to the locking device of a kind of breaker switching-on mechanism, particularly a kind of breaker switching-on mechanism.
Background technology
Present high voltage switchgear mostly is electric blocking (adopting the contact of latching electromagnet or serial connection secondary circuit) or baroque mechanical latching mode greatly in the breaker switching-on mechanism locking, is used for preventing the false switching of switchgear.The electric blocking reliability is lower, and baroque mechanical latching volume is bigger, and installs and use all cumbersome.
Summary of the invention
The purpose of this utility model is exactly the weak point in the background technology, and a kind of locking device of simple in structure, easy to operate breaker switching-on mechanism is provided.
For achieving the above object, the utility model adopts following technical scheme: the locking device of breaker switching-on mechanism, comprise mounting panel, travel switch, the manual energy storage axle of cover plate and circuit breaker, the mounting panel rear side is provided with the manual energy storage pull bar of circuit breaker, mounting panel is provided with cover plate, the left side of mounting panel upper cover plate is provided with travel switch, described locking device also comprises procedure lock, have contact with, switch knob and combined floodgate semiaxis, described mounting panel upper cover plate right side is provided with procedure lock, the procedure lock right side is provided with the combined floodgate interlock plate, have contact with an end and be connected with the left end of cover plate, its other end is connected with the plate that has contact with of combined floodgate semiaxis upper end, and it is hinged to have contact with middle part and connecting axle.
As preferably, have contact with that the junction is provided with back-moving spring between middle part and the connecting axle.
Breaker switching-on mechanism service routine lock is realized the manual and electronic while locking of circuit breaker.
The utility model is compared with background technology, has simple in structurely, easy to install and use, realizes machinery and electricly simultaneously breaker switching-on mechanism is carried out locking.
Description of drawings
Fig. 1 is the locking device structural representation of breaker switching-on mechanism.
Fig. 2 is the switch knob closedown structure schematic diagram of breaker switching-on mechanism.
Embodiment
Embodiment 1: with reference to Fig. 1 and 2.The locking device of breaker switching-on mechanism, comprise mounting panel 11, travel switch 1, the manual energy storage axle 3 of cover plate 2 and circuit breaker, mounting panel 11 rear sides are provided with the manual energy storage pull bar 3 of circuit breaker, mounting panel 11 is provided with cover plate 2, the left side of mounting panel 11 upper cover plates 2 is provided with travel switch 1, described locking device also comprises procedure lock 4, have contact with 9, switch knob 6 and combined floodgate semiaxis 7, described mounting panel 11 upper cover plates 2 right sides are provided with procedure lock 4, the right side of procedure lock 4 is provided with combined floodgate interlock plate 5, having contact with 9 right-hand member is connected with the tie point a of cover plate 2 left ends by flexible axle 13, its left end is connected with the plate 8 that has contact with of combined floodgate semiaxis 7 upper ends, and it is hinged to have contact with 9 middle part and connecting axle 12.Describedly have contact with that the junction is provided with back-moving spring 10 between 9 middle part and the connecting axle 12.
Embodiment 2: with reference to Fig. 1 and 2.The operating principle of the locking device of breaker switching-on mechanism:
A, power failure operation: the procedure lock key is inserted procedure lock 4, and be rotated counterclockwise the procedure lock key, drive cover plate 2 and move to right, thereby the manual energy storage axle 3 of circuit breaker is covered, the electric closing circuit of travel switch 1 is cut off, and has contact with 9 and hooks and have contact with plate 8 on the combined floodgate semiaxis 7.This moment on-load switch 1 can not be manually can not electric switch-on, the procedure lock key can be pulled up.
B, send electricity operation: the procedure lock key turns clockwise, and drives cover plate 2 and moves to left, thereby the manual energy storage axle 3 of circuit breaker is opened.The electric closing circuit of travel switch 1 is switched on, have contact with simultaneously 9 leave combined floodgate semiaxis 7 have contact with plate 8.This moment, on-load switch 1 can manual or electric energy-stored and combined floodgate.After on-load switch 1 closed a floodgate, combined floodgate interlock plate 5 rose, and the procedure lock key can not be extracted.
What need understand is: though present embodiment has been done more detailed explanation to the utility model; but these explanations; just to simple declaration of the present utility model; rather than to restriction of the present utility model; any innovation and creation that do not exceed in the utility model connotation all fall in the protection range of the present utility model.
