Abstract
The utility model discloses a separated position locking structure which is characterized by comprising a circuit breaker mechanism interlocking plate, an electromagnetic lock and a hand cart locking plate, wherein the circuit breaker mechanism interlocking plate is in contact with the hand cart locking plate; the electromagnetic lock is installed on a circuit breaker framework, and is provided with a locking tongue controlled electrically; a flexible structure is adopted for the locking tongue, when in the extension state, the locking tongue can block the hand cart locking plate; the hand cart locking plate and the circuit breaker mechanism interlocking plate are in contact, and can rotate axially around a rotary shaft. The separated position locking structure provided by the utility model has the beneficial effects that the structure is simple, the design is inventive, separated position locking is adopted, the clamping stagnation phenomenon brought by separated position locking in locking is prevented from occurring, accidents are prevented, and meanwhile a circuit breaker is more convenient and simpler to overhaul.
Description
Technical field
The utility model relates to the security appliance technical field, and it is the closedown structure of circuit breaker service position and test position in ac metal closing switch gear specifically.
Background technology
According to requiring switchgear should have five anti-interlocks in the national standard " GB3906 3.6～40.5KV ac metal closing switch gear ": prevent that promptly mistake from dividing, mistake is closed circuit breaker, on-load switch; Prevent the on-load branch, close isolating switch or on-load pushes the handcart stab contact of pulling out metal enclosed switchgear; Prevent charged hanging earthing conductor or splice grafting ground switch; Prevent to be with earth connection or earthed switch to close a floodgate; Prevent the mistakenly entering into charged compartment.
Locking device mainly is meant: prevent the mistake branch, close circuit breaker, prevent the on-load branch, close isolating switch, prevent charged extension (closing) earth connection (earthed switch), prevent to be with earth connection (earthed switch) to close circuit breaker (isolating switch), prevent mistakenly entering charged chamber.Conventional anti-misoperation locking mode mainly contains 4 kinds: mechanical latching, procedure lock, electrical interlock and electromagnetic lock.These closedown modes have been brought into play positive role in anti-delaying work, facts have proved, the pluses and minuses of various traditional closedown modes all fully show.
Traditional position locking device is a disjunctor, is that the handcart jam plate is linked with connecting plate with the interlock plate on the circuit breaker.Exist locking unreliable like this, maintenance is inconvenient.
In sum, to the defective of prior art, need a kind of split type position closedown structure especially, with the problem of mentioning more than solving.
The utility model content
The purpose of the utility model is to provide a kind of split type position closedown structure, through the employing special structural design, thus the purpose of realization the utility model.
The technical problem that the utility model solved can adopt following technical scheme to realize:
A kind of split type position closedown structure is characterized in that, comprises the breaker mechanism interlock plate, electromagnetic lock and handcart jam plate; Said breaker mechanism interlock plate contacts with the handcart jam plate; Said electromagnetic lock is installed on the circuit breaker frame, and has a dead bolt by electrical control, and said handcart jam plate contacts with said breaker mechanism interlock plate, and can axially rotate around the shaft.
In an embodiment of the utility model, said dead bolt adopts Collapsible structure, the set handcart jam plate that blocks when being in elongation state.
The beneficial effect of the utility model is: simple in structure, design ingeniously, and adopt the locking of split type position, the catching phenomenon that produces when preventing that the locking of Contiuum type position from bringing locking avoids accident to take place, and makes the maintenance circuit breaker more convenient, simple simultaneously.
Description of drawings
Fig. 1 is the front view of the described a kind of split type position of the utility model closedown structure.
Fig. 2 is the end view of the described a kind of split type position of the utility model closedown structure.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with embodiment, further set forth the utility model.
As depicted in figs. 1 and 2, the described a kind of split type position of the utility model closedown structure comprises breaker mechanism interlock plate 1, electromagnetic lock 2 and handcart jam plate 3; Said breaker mechanism interlock plate 1 and handcart jam plate 3; Said electromagnetic lock 2 is installed on the circuit breaker frame, and has a dead bolt by electrical control, and said handcart jam plate 3 is connected with said breaker mechanism interlock plate 1, and can axially rotate around the shaft.
In an embodiment of the utility model, said dead bolt adopts Collapsible structure, the set handcart jam plate 3 that blocks when being in elongation state.
Have only when electromagnetic lock 2 is charged, dead bolt shrinks, and handcart jam plate 3 is rotated counterclockwise 30 degree, and handcart jam plate 3 just can move.Promptly can to circuit breaker in the service position or test position carry out and to pull out or to advance breaker operator.
When circuit breaker in the service position or test position, when electromagnetic lock 2 was not charged, the dead bolt elongation was locked 3 plates with handcart and is blocked.At this moment just can't pull out circuit breaker, forward operation.
The beneficial effect of the utility model is: simple in structure, design ingeniously, and adopt the locking of split type position, the catching phenomenon that produces when preventing that the locking of Contiuum type position from bringing locking avoids accident to take place, and makes the maintenance circuit breaker more convenient, simple simultaneously.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection range to be defined by appending claims and equivalent thereof.
Claims (2)
1. a split type position closedown structure is characterized in that, comprises the breaker mechanism interlock plate, electromagnetic lock and handcart jam plate; Said breaker mechanism interlock plate contacts with the handcart jam plate; Said electromagnetic lock is installed on the circuit breaker frame, and has a dead bolt by electrical control, and said handcart jam plate contacts with said breaker mechanism interlock plate, and can axially rotate around the shaft.
2. a kind of split type position according to claim 1 closedown structure is characterized in that, said dead bolt adopts Collapsible structure, the set handcart jam plate that blocks when being in elongation state.
