Description
Technical field
The present invention relates to a kind of safety device, particularly relate to a kind of safety device for plug-in type pedestal of breaker.
Background technology
Circuit breaker refers to the electric current that can close, carry and cut-off under normal loop condition; and can close, carry in official hour and cut-off the switching device of the electric current under abnormal loop condition (comprising short circuit condition); circuit breaker is divided into primary cut-out and low-voltage circuit breaker by its scope of application, is widely used in every field at present.Usually, on the mounting panel of the complete sets of equipment, first installing the plug-in base of a circuit breaker, having the connecting plate for connecting with circuit breaker in plug-in base, plug-in base is connected with the mains line and load line in advance.During use, circuit breaker is directly injected plug-in base.If circuit breaker has been broken, as long as extract bad, change one have to.Generally in circuit breaker insertion or before extracting plug-in base; in order to personal safe protection; circuit breaker will be in open position and just can insert or extract, however artificially operation make circuit breaker be in open position often can due to carelessness cause operate miss, cause security incident.
Summary of the invention
The object of the present invention is to provide a kind of safety device for plug-in type pedestal of breaker, can extract in the process of circuit breaker in insertion and automatically make circuit breaker be in open position.
The object of the invention is to be achieved through the following technical solutions:
A kind of safety device for plug-in type pedestal of breaker, comprise push rod, spring, push rod, described push rod is arranged with spring, described push rod and spring are slidably installed in mounting groove on-board the circuit breaker, be provided with guide rail in described mounting groove, described push rod is also provided with fixed head, described fixed head is below spring, described push rod be arranged on plug-in base with described push rod opposite position, side, described push rod top is with projection.
Beneficial effect of the present invention is: can promote draw bar to driving gear of breaker trip positions cut-off breaker in the process protrusions of inserting and extracting circuit breaker, avoid circuit breaker to be in "on" position and to be inserted into or to extract, eliminate manual operation, not only to save time but also safe and reliable.

Embodiment
As shown in figs. 1 to 6 in embodiment, a kind of safety device for plug-in type pedestal of breaker of the present invention, comprise push rod 2, spring 3, push rod 5, described push rod 2 is arranged with spring 3, described push rod 2 and spring 3 are slidably arranged in the mounting groove 8 on circuit breaker 6, guide rail 9 is provided with in described mounting groove 8, described push rod 2 is also provided with fixed head 4, described fixed head 4 is below spring 3, described push rod 5 is arranged on position corresponding with described push rod 2 on plug-in base 7, and side, described push rod 2 top is with protruding 10.
During work, plug-in base 7 is connected with the mains line and load line in advance, when circuit breaker 6 be in "on" position circuit breaker 6 insert plug-in base 7 time, push rod 2 is along with the insertion of circuit breaker 6, with the push rod 5 be loaded in plug-in base 7 to touching, push rod 2 moves along guide rail 9 towards the opposite direction of direction of insertion, along with the motion of push rod 2, projection 10 on push rod 2 is collided with draw bar 1, before circuit breaker connecting plate 11 contacts with plug-in base connecting plate 12, protruding 10 promote draw bar to circuit breaker 6 transmission mechanism trip positions, make circuit breaker 6 be in off-state.Along with the continuation of circuit breaker 6 is inserted, push rod 2 continues motion, and when circuit breaker 6 inserts plug-in base 7 completely, push rod 2 stop motion, draw bar 1 is crossed protruding 10 and got back to origin-location, and circuit breaker 6 can normal occlusion separating brake.
When circuit breaker 6 is in "on" position, when circuit breaker 6 extracts plug-in base 7, spring 3 compressive deformation during owing to inserting, now under spring 3 recovers elastically-deformable active force, push rod 2 is along with the opposite direction motion of extracting towards extracting direction of circuit breaker 6, along with the motion of push rod 2, projection 10 and the draw bar 1 of push rod 2 side are collided, before circuit breaker connecting plate 11 is separated with plug-in base connecting plate 12, protruding 10 promote draw bar 1 to circuit breaker 6 transmission mechanism trip positions, make circuit breaker 6 be in off-state.Along with circuit breaker 6 continue extract, push rod 2 continues motion, and when circuit breaker 6 extracts plug-in base 7 completely, push rod 2 stop motion, draw bar 1 is crossed protruding 10 and got back to origin-location, and circuit breaker 6 can normal occlusion separating brake.
