Abstract
The utility model relates to a vacuum circuit breaker with an aviation plug protection structure. The vacuum circuit breaker with the aviation plug protection structure includes a circuit breaker body; a sealing plate is arranged on the front face of the circuit breaker body; and the sealing plate and the circuit breaker body form a chamber for holding an aviation plug. The beneficial effects are that: the structure is simple, so as to facilitate the protection of the aviation plug; and the repair operation is enabled to be more convenient and safe.
Description
Technical field
The utility model relates to vacuum circuit-breaker technical field, especially relates to a kind of vacuum circuit-breaker with aviation plug protection structure.
Background technology
Along with the development of national economy, electric network composition and part throttle characteristics are day by day complicated, for protection equipment and personal safety, the requirement of Supply Security, reliability are had higher requirement.
Modal circuit safety device is circuit breaker, and it is a kind of existing hand switch effect, can automatically carry out again decompression, under-voltage, overload and the electrical equipment of short-circuit protection.It can be used to distribute electric energy; do not start continually asynchronous motor; power circuit and motor etc. are carried out to protection, can automatic shutdown circuit in the time that serious overload or short circuit and the fault such as under-voltage occur for they, its function is equivalent to Fuse switch and the combination of crossing underheat relay etc.And after disjunction fault current, generally do not need to change parts, obtain a wide range of applications.
Because the signal output of current circuit breaker all adopts aviation plug structure, but in the process of depositing or safeguard, do not deposit the chamber of this plug, be easy to like this cause the accidental damage of plug.
Therefore, a kind of appearance of the vacuum circuit-breaker with aviation plug protection structure is necessary.
Utility model content
The utility model, for solving the problems of the technologies described above, is to provide a kind of vacuum circuit-breaker with aviation plug protection structure.
The technical problem that the utility model solves realizes by the following technical solutions:
The vacuum circuit-breaker with aviation plug protection structure, comprises breaker body, is provided with shrouding in the front of described breaker body, and described shrouding and breaker body form one in order to place the chamber of aviation plug.
As preferred technical scheme, the surface of described shrouding is densely covered with numerous louvres.
As preferred technical scheme, on described shrouding, be also provided with and place the groove indicating.
The beneficial effect the utlity model has is: simple in structure, be conducive to the protection to aviation plug, and make maintenance operation more convenient, safety.
Brief description of the drawings
Fig. 1 is the utility model: the structural representation with the vacuum circuit-breaker of aviation plug protection structure.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Shown in Fig. 1, there is the vacuum circuit-breaker of aviation plug protection structure, comprise breaker body 1, be provided with shrouding 2 in the front of breaker body 1, shrouding 2 forms one in order to place the chamber of aviation plug 3 with breaker body 1.
The surface of shrouding 2 of the present utility model is densely covered with numerous louvres 5, to strengthen radiating effect.
For the ease of the title numbering of designation equipment, on shrouding 2, be also provided with and place the groove 4 indicating.
By the application of this device shrouding 2, protect aviation plug 3 difficult drop-offs, make maintenance operation more convenient, safety.
More than show and described general 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 in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
