In an embodiment of the present utility model, described upper lock plate, lower locking plate adopt the screw fit nut to be connected with the junction of jam plate slide-bar.
In an embodiment of the present utility model, an end of described upper lock plate and lower locking plate is provided with connecting hole, and valve is opened slide-bar and is connected with lower locking plate with upper lock plate by described connecting hole.
The beneficial effects of the utility model are: simple in structure, design ingeniously, and by setting up a locking device at valve mechanism, thereby solved in the conventional art safety problem because bringing without locking between valve mechanism and valve baffle plate.
Description of drawings
Fig. 1 is the structural representation of valve blocking mechanism described in the utility model.
Fig. 2 is the test position figure of valve blocking mechanism described in the utility model.
Fig. 3 is the service position figure of valve blocking mechanism described in the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
Such as Fig. 1, Fig. 2 and shown in Figure 3, a kind of valve blocking mechanism described in the utility model, it comprises that one is installed on valve mechanism on the breaker chamber left side plate by the first supporting bracket 4, on the described valve mechanism locking device is installed; Described locking device comprises jam plate 3, jam plate slide-bar 7, the second supporting bracket 10 and spring;
Described jam plate comprises upper lock plate and lower locking plate, the centre position of upper lock plate and lower locking plate is provided with the groove of opening slide-bar for the locking valve, one end of upper lock plate and lower locking plate and the second supporting bracket are flexibly connected, and the other end of upper lock plate and lower locking plate is provided with the jam plate slide-bar; Described jam plate slide-bar is provided with two, is installed on respectively an end of upper lock plate and lower locking plate.
The spring of present embodiment comprises that the first spring 5 and the second spring 6, the first Spring Cards are connected between the second supporting bracket and the first supporting bracket, and the two ends of the second spring connect upper lock plate and lower locking plate.Described upper lock plate, lower locking plate adopt the screw fit nut to be connected with the junction of jam plate slide-bar.
End at upper lock plate and lower locking plate is provided with connecting hole, and the second supporting bracket is connected with lower locking plate with upper lock plate by described connecting hole.
The valve blocking mechanism is fixed on the left side plate of breaker chamber by the first supporting bracket 4, and upper and lower axis 8 is connected with valve baffle plate connecting rod, and the first spring 5 installing cards are connected on the second supporting bracket 10 and the first supporting bracket.Circuit breaker place test position or when shifting out rack, under the effect of the first spring 5, the second supporting bracket 10, the valve baffle plate is electrified body and breaker chamber isolation, and jam plate 3 pins valve and opens slide-bars 2 and carries out the locking of valve baffle plate, and the valve baffle plate can not be opened up and down.
When circuit breaker moves to the service position from test position, lower jam plate slide-bar 7 of effect that valve on circuit breaker is opened guide plate down presses, jam plate 3 is opened slide-bar with valve and is discharged, and the valve unlatching guide plate on the circuit breaker down presses valve unlatching slide-bar 7 simultaneously.Because axis 8 is welded on the second supporting bracket 10 and is connected with valve baffle plate connecting rod, thus the valve baffle plate open up and down, until circuit breaker shakes the service position.After circuit breaker shook out test, under the effect of the first spring 5 and the second spring 6, the valve blocking mechanism returned to again blocking.
The utility model is by increasing jam plate, jam plate slide-bar, the first supporting bracket, spring at original valve mechanism.When circuit breaker was in test position, the jam plate on the valve blocking mechanism was opened slide-bar with valve and is pinned, and the valve baffle plate can not be opened up and down.When circuit breaker is mobile to the service position operation, valve on the circuit breaker is opened guide plate the jam plate slide-bar on the valve blocking mechanism is down pressed, and opens slide-bar thereby discharge valve, opens under the guide plate effect at the valve on the circuit breaker, the valve baffle plate can be opened up and down, and circuit breaker can shake to the service position.When circuit breaker shakes out test position or shifts out rack, under the effect of valve blocking mechanism spring, recover again blocking, thereby realized the locking of valve baffle plate.
More than show and described basic 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 describes in above-described embodiment and the specification just illustrates principle of the present utility model; 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 changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
