Abstract
The utility model discloses a misoperation electrical lock for a high-voltage complete-set switch cabinet and relates to the technical field of misoperation locks for the high-voltage complete-set switch cabinets. The misoperation electrical lock comprises a secondary control loop of the high-voltage complete-set switch cabinet, and is characterized in that the secondary control loop is connected with a travel switch, and a travel switch is arranged on an operation mechanism of a mechanical lock. The misoperation electrical lock disclosed by the utility model has the advantages of reasonable design and high safety performance, the travel switch is increased on an original operation interlocking mechanism and forms linkage with the secondary control loop, and when a misoperation occurs, a circuit breaker can be tripped automatically so as to realize mechanical and electrical double-safety protection.
Description
Technical field:
The utility model relates to high pressure voltage switchgear incorrect manipulation deadlock technical field, relates in particular to a kind of high pressure voltage switchgear misoperation electric blocking.
Background technology:
Used high pressure voltage switchgear all is to adopt mechanical latching (being the five rings interlocking) mode separately at present, or the electrical interlock mode; The latch-up protection mode is comparatively single; In case latch-up protection is broken down, accident probably appears, cause the damage of equipment and harm people's life.
The utility model content:
The utility model technical problem to be solved is to overcome the defective of prior art, and a kind of high pressure voltage switchgear misoperation electric blocking is provided.
The utility model technical problem to be solved adopts following technical scheme to realize:
High pressure voltage switchgear misoperation electric blocking comprises high pressure voltage switchgear secondary control loop, and it is characterized in that: said secondary control loop is connected with travel switch.
Said travel switch is arranged on the operating mechanism of mechanical latching.
On the operating mechanism of mechanical latching, add a travel switch and be connected, can realize machinery, electric double insurance with secondary control loop.
The utility model is reasonable in design, and security performance is high, in original operation interlocking device, has increased a travel switch, constitutes interlock with secondary control loop, when misoperation occurring, can let the circuit breaker automatic trip, realizes machinery, electric dual security protection.
Description of drawings:
Fig. 1 is the sketch map of the utility model.
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 concrete diagram, further set forth the utility model.
As shown in Figure 1, high pressure voltage switchgear misoperation electric blocking comprises high pressure voltage switchgear secondary control loop 1, and secondary control loop 1 is connected with travel switch 2, and travel switch 2 is arranged on the operating mechanism of mechanical latching.
On the operating mechanism of mechanical latching, add a travel switch and be connected, can realize machinery, electric double insurance with secondary control loop.
More than show and described the advantage of basic principle, principal character and the utility model of 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.
