Background technology
The complete power distribution cabinet of MNS type low pressure draw-out type is for adapting to the demand of electric power industry development, the Introduced From Abroad state-of-the-art technology has the Combined low-tension switch cabinet system of contemporary world advanced level and is improved the high type low-voltage distribution cabinet of exploitation, the needs of the various power supplies of this product adaptation, distribution are widely used in the various low-voltage distribution systems such as power plant, transformer station, hotel, industrial and mining enterprises building, urban construction.The frame structure that MNS adopts has high degree of flexibility, in cabinet, different standard components can be installed, to satisfy various applicable requirements.For the power distribution cabinet drawer device, very high for the safety requirements of operation, be interlocking mechanism for the device in switch cabinet drawer, in the time of usually need to opening drawer, the arrow of drawer right need to be pointed to disconnection, just can operate.When drawer was opened, the starting drive of equipment was restricted, and drawer must be closed, and connection is pointed in the arrow indication, and just can enable equipment this moment.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of switch and drawer push-and-pull power assisting device of power distribution cabinet, have characteristics simple in structure, easy to use and safe.
To achieve these goals, the technical solution used in the present invention is: a kind of switch of power distribution cabinet and drawer push-and-pull power assisting device, include the drawer door baffle plate, the drawer door baffle plate is provided with the drawer slide kayser, the drawer slide kayser is meshed with the kayser gear, also be engaged with switch gear on the drawer slide kayser, switch gear is meshed with switch guide rail on being located at the drawer door baffle plate, and switch guide rail top is provided with switch arrow indicating knob.
Described drawer slide kayser is fixed on the drawer door baffle plate by the guide rail fixed card.
Described kayser gear external shaft is provided with the outer handle jack in the heart.
Described kayser gear internal axis is provided with booster, and booster is provided with curved groove, and the booster outer face is provided with locating shaft.
The invention has the beneficial effects as follows:
The present invention links the push-and-pull power assisting device of drawer and the switch of power distribution cabinet, make it form integrated apparatus, by the push-and-pull of drawer being controlled the switch of power distribution cabinet, when namely drawer is opened, corresponding switch arrow indicating knob is in off-state, and this moment, power distribution cabinet switch can not act on.After drawer is closed and is locked,
Switch arrow indicating knobBe in connection status, pressing power distribution cabinet switch both can starting device, and be convenient to the staff and operate, and improved the fail safe that equipment is implemented.
Description of drawings
Fig. 1 is switch and the drawer push-and-pull assisting integration device structure chart of power distribution cabinet.
Fig. 2 is the power assisting device structure chart of this apparatus integration.
Embodiment
Referring to Fig. 1,2, a kind of switch of power distribution cabinet and drawer push-and-pull power assisting device, include drawer door baffle plate 1, drawer door baffle plate 1 is provided with drawer slide kayser 2, drawer slide kayser 2 is meshed with kayser gear 4, also is engaged with switch gear 5 on drawer slide kayser 2, and switch gear 5 is meshed with switch guide rail 7 on being located at drawer door baffle plate 1, switch guide rail 7 tops are provided with switch arrow indicating knob 6
Described drawer slide kayser 2 is fixed on drawer door baffle plate 1 by guide rail fixed card 8.
Described kayser gear 4 external shafts are provided with outer handle jack 3 in the heart.
Drawer door baffle plate 1, drawer slide kayser 2, outer handle jack 3, kayser gear 4, guide rail fixed card 8 form the drawer push-pull device at fixed.
Described kayser gear 4 internal axis are provided with booster 9, and booster 9 is provided with curved groove 10, and booster 9 outer faces are provided with locating shaft 11.Switch gear 5, switch arrow indicating knob 6, switch guide rail 7, curved groove 10, locating shaft 11 form switching device.
The switching device of described power distribution cabinet, the power supply that needs when referring to equipment investment is moved is controlled the break-make of power supply by switch.
Described booster is to consider that the push-and-pull due to drawer freely may not cause the damage of drawer, therefore increases booster and makes the push-and-pull of drawer smooth and easy, reduces and installs and the workload of maintenance and the failure rate of appearance.
Described drawer slide kayser is that switching device and drawer push-pull device at fixed are combined, and by the push-and-pull of drawer being controlled the switch of power distribution cabinet, when namely drawer was opened, corresponding switch arrow indicating knob was in off-state, and this moment, power distribution cabinet switch can not act on.After drawer was closed and locked, switch arrow indicating knob was in connection status, and pressing power distribution cabinet switch both can starting device.
Operation principle of the present invention is: outer handle is inserted into outer handle jack 3 places, pass through rotary handle, under the effect of the curved groove 10 on booster 9 and locating shaft 11, make the push-and-pull of drawer smooth and easy, simultaneously when rotary handle, driving kayser gear 4 is rotated, drawer slide kayser 2 moves, switch gear 5 rotates under the active force of drawer slide kayser 2, adjust the position of switch guide rail 7, the switch arrow knob 6 that be connected with switch guide rail 7 this moment moves, and determines connection and the off-state of system.
Detailed process is as follows: when drawer is in closed condition, turn clockwise by the outer handle that is inserted into outer handle jack 3, drawer slide kayser 2 tops move right, the below is moved to the left kayser is opened, below drawer slide kayser 2 drives switch gear 5 rotations simultaneously, switch guide rail 7 is moved right, and switch arrow indicating knob 6 is along with switch guide rail 7 moves right, and this moment, the switch arrow pointed to off-state.When drawer is opened, handle is rotated counterclockwise, and drawer slide kayser 2 snaps in box house at this moment, and switch gear 5 is moved to the left switch guide rail 7 along with drawer slide kayser 2 moves right, switch arrow indicating knob 6 is moved to the left at this moment, and the switch arrow points to connection status.
