Detailed description of the invention
Below in conjunction with embodiment, the utility model is elaborated. Wherein identical parts represent with identical Reference numeral. Fig. 2 is the schematic diagram of first embodiment of the utility model breaker controlling device. As shown in Figure 2, in first embodiment of the present utility model, breaker controlling device comprises stacked switch 2, transformer station 3, controller 4 and contactor 5.
Described controller 4 is for sending control signal, and acceptance is from the feedback signal of described stacked switch 2. Described controller 4 can be preferably mining intrinsic safety type controller, adopts in the present embodiment Huaning KTC101 controller.
Described stacked switch 2, for receiving the control signal from described controller 4, is electrically connected with described disintegrating machine 1, and according to the start and stop of disintegrating machine 1 described in described control signal control. The signal input part of described stacked switch 2 is connected with the signal output part of described controller 4, the feedback output end of described stacked switch 2 is connected with the feedback input end of described controller 4, signal input and output between described controller 4 and described stacked switch 2 and feed back input output can realize by input/output interface circuit, for example, can adopt the Industry Control input/output port of standard to realize. Described controller 4 transmits control signal by signal output part, and sends to described stacked switch 2 by the signal input part of described stacked switch 2, thereby controls the start and stop of described disintegrating machine 1; Described stacked switch 2 sends feedback signal by feedback output end, and sends to described controller 4 by the feedback input end of described controller 4.
Described transformer station 3 is used to described disintegrating machine 1 to power, and the electric output out-put supply of described transformer station 3 arrives described disintegrating machine 1, thereby maintains the normal electricity consumption of described disintegrating machine 1.
Described breaker controlling device also comprises contactor 5, for tripping in described transformer station 3 or disconnecting the feedback line between described controller 4 and described stacked switch 2 when other accident power-off. Described contactor 5 can be preferably A.C. contactor 5. The main contact 5a of described contactor 5 is connected to the electric output of described transformer station 3, is preferably connected in the supply line between described transformer station 3 and described disintegrating machine 1. The normal opened contact 5b of described contactor 5 is connected in the circuit between described feedback input end and described feedback output end. In the time of described transformer station 3 normal power supply, the normal opened contact 5b closure of described contactor 5, the feedback line between described stacked switch 2 and described controller 4 is on-state. Described main contact 5a is connected with the main coil of described contactor 5 inside, and in the time that described main contact 5a does not have electric current input, described main coil must not be electric, and described normal opened contact 5b remains open state; In the time that described main contact 5a has electric current input, described main coil, because obtaining the electric magnetic field that produces, under the effect in magnetic field, makes two contact adhesives of described normal opened contact 5b, thereby makes normal opened contact 5b closure.
In the time that described disintegrating machine 1 is carried out to normal on off control, while sending instruction and control the start and stop of described disintegrating machine 1 by described controller 4, described transformer station 3 is continued power states, the electric output of described transformer station 3 is "on" positions, because the main contacts of described contactor 5 and the electric output of described transformer station 3 are connected, therefore the main contact 5a of described contactor 5 has electric current input, the main coil of described contactor 5 is because obtaining the electric magnetic field that produces, under the effect in magnetic field, two contact adhesives of the normal opened contact 5b of described contactor 5, described normal opened contact 5b is in closure state. therefore, in the time of normal on off control, the circuit between the feedback output end of described stacked switch 2 and the feedback input end of described controller 4 is closure state, and the access of described contactor 5 can not have influence on the normal on off control of described disintegrating machine 1.
For example, when the power-off that meets accident (described transformer station 3 trips), the electric output of described transformer station 3 is no longer powered, make the main contact 5a of described contactor 5 there is no electric current input, the main coil of described contactor 5 is not because producing magnetic field by electricity, two contacts of the normal opened contact 5b of described contactor 5 are owing to not having the effect in magnetic field to fail adhesive, described normal opened contact 5b is disconnected, thereby the circuit between the feedback output end of described stacked switch 2 and the feedback input end of described controller 4 is disconnected, described controller 4 just cannot receive the feedback signal of described stacked switch 2, described controller 4 just can judge that described stacked switch 2 disconnects, be equivalent to the program of orderly closedown. in this case, if after again restoring electricity, first described controller 4 sends early warning signal, has ensured the clean boot of described disintegrating machine 1, has avoided the direct accident that starts described disintegrating machine 1 and cause without early warning in the situation that.
Fig. 3 is the schematic diagram of second embodiment of the utility model breaker controlling device. As shown in Figure 3, described breaker controlling device also comprises alarm 6, and described alarm 6 is connected in series with the normally closed contact 5c of described contactor 5. Preferably, described alarm 6 can comprise power supply 6a and indicator lamp 6b, is connected to the two ends of the normally closed contact 5c of described contactor 5 after described power supply 6a and described indicator lamp 6b series connection. More preferably, described alarm 6 is also in series with buzzer or electric bell, for the alarm signal of sounding. Described main contact 5a is connected with the main coil of described contactor 5 inside, and in the time that described main contact 5a does not have electric current input, described main coil must not be electric, and described normally closed contact 5c is kept closed; In the time that described main contact 5a has electric current input, described main coil, because obtaining the electric magnetic field that produces, under the effect in magnetic field, makes two contact separation of described normally closed contact 5c, thereby normally closed contact 5c is disconnected.
In the time meeting accident power-off, the main contact 5a of described contactor 5 does not have electric current input, the main coil of described contactor 5 must not be electric, make the normally closed contact 5c of described contactor 5 in closure state, connect the circuit of described alarm 6, described indicator lamp 6b is lighted, and described voice guard 6 is reported to the police, thereby reminds staff to carry out in time plant maintenance.
Adopt the utility model breaker controlling device, by the backfeed loop between described stacked switch 2 and described controller 4, contactor 5 is set, make disintegrating machine 1 in the time meeting accident power-off, described control device can disconnect the backfeed loop between disintegrating machine 1 and controller 4, after again powering, controller 4 can send early warning to disintegrating machine 1 again, ensures that disintegrating machine 1 starts under default condition, has improved the security that disintegrating machine 1 moves.
