Brief description of the drawings
Fig. 1 is principle schematic of the invention.
Wherein, reference correspondence title is as follows；1.-breaker auxiliary contact BG1,2.-switching-in spring energy storage contact
BW1,3.-locking relay BSJ, 4.-supervisory relay TWJ, 5.-counter, 6. current-limiting resistance.
Embodiment
The invention will be further described with reference to the accompanying drawings and examples.Embodiments of the present invention include but is not limited to
The following example.
Embodiment
As shown in figure 1, present embodiments providing a kind of outlet breaker closing circuit structure, the loop structure is to existing
Outlet breaker closing circuit is optimized, and it accesses locking relay BSJ in outlet breaker closing circuit；Further
, locking relay BSJ is arranged between breaker auxiliary contact BG1 and switching-in spring energy storage contact BW1, wherein, combined floodgate bullet
Spring energy storage contact BW1 is used to receive a distant place or order of now closing a floodgate.Think except above-mentioned, in the loop structure disclosed in the present embodiment
Remaining structure being related to can use structure same as the prior art or similar, therefore will not be repeated here.
By above-mentioned setting, the outlet breaker closing circuit structure that the present embodiment is provided, increased locking relay
BSJ increases barring condition in outlet breaker closing circuit, efficiently solves in the prior art, breaker is in gate-dividing state
When, switching-in spring energy storage contact BW1 is connected, and breaker auxiliary contact BG1 (or S0) is connected, due to without other barring conditions, only
Order of closing a floodgate come closing coil will direct action defect.
In the present embodiment, locking relay BSJ is made up of auxiliary reclay and its self-keeping circuit.
Easy for installation in order to operate, locking relay BSJ is arranged in circuit breaker operation mechanism case.
