Abstract
The utility model discloses a manual switch-on/switch-off misoperation-preventing device. The manual switch-on/switch-off misoperation-preventing device is suitable for a circuit breaker. The number of the poles of the circuit breaker can be one or three or four. The manual switch-on/switch-off misoperation-preventing device includes a switch-off pull ring and a switch-on pull ring; the switch-off pull ring is connected with a switch-off buffer plate; the switch-on pull ring is connected with a switch-on buffer plate; and the switch-off buffer plate is connected with the switch-on buffer plate through a rotating shaft. With the manual switch-on/switch-off misoperation-preventing device of the utility model adopted, when an operator uses a tool to forcedly pull down the switch-off pull ring and the switch-on pull ring so as to perform switch-off and switch-on operation on the circuit breaker, the rigidness of the switch-off buffer plate and the switch-on buffer plate can ensure forces required by normal switching off and switching on of the circuit breaker; when the pulling-down force of a user is excessively large, the switch-off buffer plate and the switch-on buffer plate bend naturally, and therefore, it can be ensured that a switch-off/switch-on connecting piece will not be damaged because of the excessively-applied force; and after the switch-off and switch-on operation are completed, and the buffer plates can recover initial states by means of elastic forces of the buffer plates themselves.
Description
Technical field
The utility model relates to the technical field that is applicable to the manual breaking-closing operating of circuit breaker, particularly a kind of manual divide-shut brake error-proof device.
Background technology
Circuit breaker refers to close and closes, carries and cut-off electric current under the normal loop condition, and can close close, in the in setting time carrying with cut-off the switching device of the electric current under the unusual loop condition (comprising short circuit condition).Circuit breaker can be used to distribute electric energy; do not start continually asynchronous motor; power circuit and motor etc. are carried out protection, can automatic shutdown circuit when serious overload or short circuit and the fault such as under-voltage occur for their, its function is equivalent to Fuse switch and the combination of crossing underheat relay etc.And behind the disjunction fault current, generally do not need to change parts.At present, obtain a wide range of applications.Existing circuit breaker is in order to prevent operate miss; operated by rotary motion is useful on separating brake draw ring and the separating brake draw ring of manual divide-shut brake; when operating personnel's tool using spurs separating brake draw ring and combined floodgate draw ring downwards circuit breaker is carried out separating brake and closing operation, often can be because the excessive circuit breaker that causes of exerting oneself be damaged.
The utility model content
In view of this, the utility model provides a kind of manual divide-shut brake error-proof device, can solve the excessive impaired problem of circuit breaker that causes of exerting oneself.
For solving above technical problem, the technical solution of the utility model is, a kind of manual divide-shut brake error-proof device, described manual divide-shut brake error-proof device is applicable to circuit breaker, described manual divide-shut brake error-proof device comprises separating brake draw ring, combined floodgate draw ring, described separating brake draw ring connects the splitting lock cushioning plate, and described combined floodgate draw ring is connected with the combined floodgate buffer board, and described splitting lock cushioning plate and described combined floodgate buffer board link together by rotation axis.
As preferred technical scheme, the number of poles of described circuit breaker is single-stage or three utmost points or level Four.
As preferred technical scheme, the equal diameters of described separating brake draw ring and described combined floodgate draw ring.
As preferred technical scheme, the equal in length of described splitting lock cushioning plate and described combined floodgate buffer board.
As preferred technical scheme, described rotation axis adopts bolt to be fixedly connected on circuit breaker.
Further preferred technical scheme is marked with direction arrow down on the described splitting lock cushioning plate, be used for prompting pulling downwards and carry out manual brake separating.
Preferred technical scheme also has, and is marked with direction arrow down on the described combined floodgate buffer board, is used for prompting pulling downwards and carries out manual brake separating.
Compared with prior art, the utlity model has following advantage:
In this application, a kind of manual divide-shut brake error-proof device is disclosed, when operating personnel's tool using when firmly downwards pulling separating brake draw ring and combined floodgate draw ring carry out separating brake and closing operation to circuit breaker, the rigidity of splitting lock cushioning plate and combined floodgate buffer board itself can guarantee the required power of the normal divide-shut brake of circuit breaker, when the downward pulling force of user is excessive, splitting lock cushioning plate and combined floodgate buffer board produce the natural torsion effect, guarantee that the divide-shut brake connector can be because of excessive damage of exerting oneself.After divide-shut brake was complete, buffer board was by the elastic returning initial condition of self.
