Description
Technical field
The utility model relates to power circuit area of maintenance, specifically, relates to a kind of magnetic-type knife switch preventing false switching.
Background technology
Power department safety regulation for operations specifies: can not charged point, conjunction chopper switch.And in real work, often there is violation operation, when the non-power-off of upper level switch, charged point, conjunction chopper switch, lead to personal injury and device damage.
Summary of the invention:
The technical problems to be solved in the utility model is to provide a kind of magnetic-type knife switch preventing false switching, prevents charged false switching from causing the shortcoming of personal injury and device damage.
The utility model adopts following technical scheme to realize goal of the invention:
A kind of magnetic-type knife switch preventing false switching, comprise base, it is characterized in that: described base is provided with two plug-in strip hinges, through a L-type magnetic force post on described plug-in strip hinge, one end of described magnetic force post is connected on described base by reset jump ring, the both sides of described magnetic force post are provided with symmetrical making electromagnet and open a sluice gate electromagnet, described magnetic force post is through plug-in strip, the end of described plug-in strip is provided with locking hole, described base is also provided with described plug-in strip with the use of open a sluice gate copper sleeve and combined floodgate copper sleeve, describedly open a sluice gate copper sleeve is provided with to open a sluice gate lock pin, described combined floodgate copper sleeve is provided with combined floodgate lock pin, describedly open a sluice gate lock pin and the equal connection control line of combined floodgate lock pin, described base is provided with control button.
As the further restriction to the technical program, described control line connection device switch.
Compared with prior art, advantage of the present utility model with good effect is: plug-in strip of the present utility model is in the state vertical with base under the effect of reset jump ring, the combined floodgate lock pin in the electromagnetic lock locking mechanism of both sides and open a sluice gate lock pin be also in contraction state under the effect of electromagnetic switch.When pressing switch knob, making electromagnet obtains electric generation magnetic force, is held by magnetic force post, and coaxially, under the drive of magnetic force post, plug-in strip turns in combined floodgate copper sleeve for magnetic force post and plug-in strip.Now, synchronously press the switch on the equipment of being arranged on, the action of combined floodgate locking electromagnetic switch, lock pin stretches out, and plug-in strip and combined floodgate copper sleeve is locked together by locking hole.Because electromagnet excitation needs through an of short duration time, so operating personnel are after pressing switch knob, plug-in strip can't close immediately, doing so avoids operating personnel and contacts with the direct of conducting wire, prevents from getting an electric shock.Control line is connected with the switch on equipment; when equipment is in operation or stopped status; disconnecting link pins by lock pin; only have after the switch on equipment is pressed; lock pin could unlock; doing so avoids maintenance personal when carrying out overhaul of the equipments, other staff open by mistake disconnecting link, the accident caused casualties.

Embodiment:
Below in conjunction with embodiment, further illustrate the utility model.
See Fig. 1-Fig. 3, the utility model comprises base 8, described base 8 is provided with two plug-in strip hinges 13, through a L-type magnetic force post 12 on described plug-in strip hinge 13, one end of described magnetic force post 12 is connected on described base 1 by reset jump ring 11, the both sides of described magnetic force post 12 are provided with symmetrical making electromagnet 10 and open a sluice gate electromagnet 9, described magnetic force post 12 is through plug-in strip 14, the end of described plug-in strip 14 is provided with locking hole 8, described base 1 is also provided with described plug-in strip 14 with the use of open a sluice gate copper sleeve 3 and combined floodgate copper sleeve 4, describedly open a sluice gate copper sleeve 3 is provided with to open a sluice gate lock pin 6, described combined floodgate copper sleeve 4 is provided with combined floodgate lock pin 5, describedly open a sluice gate lock pin 6 and combined floodgate lock pin 5 all connection control lines 7, described base 8 is provided with and opens a sluice gate button 1 and switch knob 2.
Described control line 7 connection device switch (not shown).
Plug-in strip 14 is in the state vertical with base 8 under the effect of reset jump ring 11, combined floodgate lock pin in the electromagnetic lock locking mechanism of both sides 5 and open a sluice gate lock pin 9 be also in contraction state under the effect of electromagnetic switch.When pressing switch knob 2, making electromagnet 10 obtains electric generation magnetic force, is held by magnetic force post 12, and coaxially, under the drive of magnetic force post 12, plug-in strip 14 turns in combined floodgate copper sleeve 4 for magnetic force post 12 and plug-in strip 14.Now, synchronously press the switch on the equipment of being arranged on, the action of combined floodgate locking electromagnetic switch (not shown), lock pin stretches out, by locking hole 15, plug-in strip 14 and combined floodgate copper sleeve 4 are locked together, the course of work and the combined floodgate copper sleeve 4 of opening a sluice gate copper sleeve 3 and plug-in strip 14 are similar, do not repeat them here.
Because electromagnet excitation needed through an of short duration time, so operating personnel are after pressing switch knob 2, plug-in strip 14 can't close immediately, doing so avoids operating personnel and contacts with the direct of conducting wire, prevents from getting an electric shock.
Control line 7 is connected with the switch on equipment; when equipment is in operation or stopped status; disconnecting link pins by lock pin; only have after the switch on equipment is pressed; lock pin could unlock; doing so avoids maintenance personal when carrying out overhaul of the equipments, other staff open by mistake disconnecting link, the accident caused casualties.
