The empty slot 10 at the top of the observation frame 9 is provided with a certain allowance, so that the explosion-proof glass 11 can move upwards in the empty slot.
As shown in fig. 3, the support block 12 includes a mounting portion and a locking portion. One end of the mounting part is fixed on the outer surface of the explosion-proof glass 11, and the other end of the mounting part is vertically fixed with the locking part. The locking part is provided with a second plugging hole 14 corresponding to the first plugging hole 13. A third insertion hole 15 is formed at one side of the support block 12, and an insertion rod 16 is inserted into the third insertion hole 15. The end of the insertion rod 16 exposed out of the third insertion hole 15 is fixedly provided with a thin rod 21.
Third plug-in hole 15 provides the position of placing for inserted bar 16 at ordinary times, avoids can't finding inserted bar 16 when the switch board takes place emergency, and can not carry out corresponding emergency treatment operation, designs slender pole 21 in the one end of inserted bar 16, and the operating personnel of being convenient for extracts inserted bar 16 from third plug-in hole 15.
When normal, operating personnel can observe the inside condition of switch board through explosion-proof glass 11, and the bottom of supporting shoe 12 is because on the terminal surface under the gravity falls observation frame 9.
When an emergency fault occurs, an operator moves the supporting block 12 upwards and drives the explosion-proof glass 11 to move upwards in the empty groove 10 at the same time until the second plugging hole 14 on the supporting block 12 is aligned with the first plugging hole 14, and the explosion-proof glass 11 is inserted into the first plugging hole 13 and the second plugging hole 14 by using the plugging rod 16, at the moment, most of the explosion-proof glass 11 is positioned in the empty groove 10 at the top of the observation frame 9, a large-volume space can be leaked from the observation frame 9, and the operator can maintain the interior of the power distribution cabinet through the leaked space; and be provided with the observation frame 9 of the same setting of a plurality of on cabinet door 2, be two in this embodiment, make things convenient for operating personnel to maintain the trouble that is in different positions in the switch board.
Example two:
a regional power distribution unit for facilitating emergency maintenance is improved with respect to the support blocks 12 and the insert rods 16. The plunger 16 is connected to the support block 12 by a bungee cord. One end of the elastic rope is fixedly connected with the thin rod 21, and the other end of the elastic rope is fixedly connected with the supporting block 12.
The elastic rope is used for connecting the inserted link 16 and the supporting block 12, so that the inserted link 16 is prevented from being lost, and the inserted link 16 can be found in time when needed. And the elastic cord has elasticity, so that the work of inserting the insertion rod 16 into the first insertion hole 13 and the second insertion hole 14 is not influenced.
The present embodiment is modified only for the support block 12 and the plunger 16, and the other portions are the same as those of the first embodiment.
Example three:
a regional power grid distribution device convenient for emergency maintenance optimizes a first plugging hole 13.
As shown in fig. 4, the diameter of the second insertion hole 14 is larger than that of the first insertion hole 13. The upper and lower ends of the first plugging hole 13 are respectively provided with a raised elastic sheet 24.
When the emergent maintenance of needs, operating personnel lifts up explosion-proof glass 11 through supporting shoe 12, when the second is inserted tight hole 14 and is passed through first tight hole 13 of inserting, the second is inserted tight hole 14 and can be passed through shell fragment 24, shell fragment 24 carries out preliminary location to second insertion tight hole 14, operating personnel can obviously feel the change of power, know that second insertion tight hole 14 has already been aimed at first tight hole 13 of inserting tentatively, insert first tight hole 13 of inserting and second insertion tight hole 14 with inserted bar 16 again, later carry out emergent maintenance.
The elastic sheet 24 is used for performing primary positioning on the second plugging hole 14 to assist in alignment, and informing an operator that the two plugging holes are aligned through force change, so that the elastic sheet is conveniently applied to emergency maintenance operation, and cannot cause great influence on the original emergency operation.
In the present embodiment, only the first plugging hole 13 is optimized, and the rest is the same as the first embodiment.
