Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a safety shutter device for a σ1 type breaker, and in particular to one in which an interphase barrier can be disposed between each phase of the breaker.

[Prior art]

Conventionally, in the safety shutter device of this Yuzu drawer-type breaker, the main circuit conductor inside the drawer frame was hidden by an integrated insulating board. .

[Summary of the invention]

This invention was made in order to eliminate the drawbacks of the above-mentioned conventional devices, and by arranging insulating plates for each phase of the circuit breaker to hide the main motor M=% body in the drawer frame, between the insulating plates of each phase. An object of the present invention is to provide a safety shutter device for a pull-out type breaker that can provide good safety by disposing a mutual barrier between the two sides.

[Embodiments of the invention]

An embodiment of the present invention will be described with reference to FIGS. 1 to 5. @ Figure 1 is a schematic perspective view of the entire device (however, only a portion of the insulating plate and the interlayer barrier are shown), and Figures 2 (2) to 4 are cross-sectional views showing three different operating positions of the shutter device. Plan view Figure 5 is an enlarged view of the main parts of the opening signal. In the figure (1) is the fixed drawer frame of the breaker (2), and the two left and right side plates (1a) and the upper and lower main circuit conductors that connect these both side plates (1a) (3 phases, 12 poles in Figure 1n), (5) is a phase 1 river barrier placed between each phase of the main circuit conductor (3), and is attached, for example, by the above-mentioned fixed \Ad' (4).

9C) and is supported by the slide plate (9) without moving in the interphase direction, and the other insulating board (IOB) is fixed to the slide plate (9) and moves in the interphase direction. (IOA) is provided with holes (1, 0 & ) for connection with the main circuit conductors (3) and the corresponding main circuit conductors (3) binding holes...'the main circuit conductors (2a), and the insulating board (IOB

Next, I will briefly explain the operation. In Figure 2, the breaker (2) is pulled out, the drive plate (6) is pulled back by the spring (8), and the break plate (10A) is activated by the break b & (IOB). Hole (10

). At this time, the slide plate (9
) is allowed to enter by a pin (IC) that engages with the L-dimensional elongated hole (9b). As the slide plate (9) slides, the insulating plate (10B) also slides in the same direction, and as shown in FIG.
The hole (10a) is opened by engaging with the hole (10a) of the OA). At this time, the hole (10a) on the rear side of the insulation 1 (IOA) hole (ILl&) when viewed from the slide direction.
is released from the sliding am tear (10B). In addition, if the power S matchmaker is used (2), the pin (6)

) The breaker side conductor (2a) is connected to the bundle conductor yh (3) protruding from the breaker side conductor (2a). In addition, when the breaker (2) is pulled out from the matchmaker state shown in Fig. 4, the driving plate (6), slide plate (9), insulating plate (IOA), ( IOB) are each evicted and return to the state of being a member of the vessel (2) in Figure 2.
By providing the driving plates (6) on the left and right sides as in the above embodiment, the operation of applying an eccentric external force at the time of breaking the wire (2) becomes stable. By placing insulating plates that hide the main circuit conductors in the drawer frame at the valleys of the circuit breakers, a phase barrier can be placed between the insulating plates of each phase. ＠Is there any effect that overall strength is strengthened and safety is obtained?
