Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
As shown in fig. 1, the circuit structure of the single-stage interlock control unit is shown, wherein SA1 is an interlock selection switch, 4-1 and 4-2 are two input terminals of the present-stage interlock unit, 4-3 and 4-4 are two output terminals of the present-stage interlock unit, SB1 is a stop button, SB2 is a start button, KM1 is a contactor, FR1 is a thermal relay, HR1 is an operation indicator lamp, and HR2 is a fault indicator lamp.
Whether the single equipment is in the single-body position or the interlocking position can be selected through the selection switch SA1, when the selection switch contact 4.2 is closed, namely the single-body position is selected, the equipment at the current stage can be independently started without interlocking control, and therefore the single equipment is very convenient to debug. The starting button SB2 is pressed, the coil of the contactor KM1 is electrified, the normally open contact of the contactor KM1 is closed, the operation indicator lamp HR1 is electrified and is lightened, meanwhile, the two output terminals 4-3 and 4-4 of the current-stage interlocking unit are connected through the normally open contact closed by the contactor KM1, but the starting button of the main control unit of the previous-stage single-body equipment is not pressed, so that the previous-stage single-body equipment is not influenced. When the control unit stop button SB1 is disconnected, the main control unit is powered off, and the single equipment stops running; or triggering the thermal relay FR1, opening the normally closed contact of the thermal relay FR1, stopping the operation of the single equipment, closing the normally open contact of the thermal relay FR1 and lighting an alarm by the fault indicator lamp HR 2. When the selector switch contact 4.1 is closed, namely the interlock operation position is selected, the devices need to be operated in an interlock mode.
In this embodiment, the interlocking operation is described by taking the three-stage device interlocking shown in fig. 2 as an example, and may be in multiple stages in reality. In the device 2, when the contact 2.1 of the selector switch is closed, the interlock position is selected for the current stage of the device:
when the interlocking device operates in an interlocking mode, the two input terminals 2-1 and 2-2 of the interlocking unit of the equipment at the current stage need to be communicated, namely under the condition that the two output terminals 3-3 and 3-4 of the interlocking unit of the equipment at the later stage are communicated, the starting button SB22 is pressed, the coil of the contactor KM21 can be electrified for attraction, and the equipment at the current stage can be started; when the rear-stage equipment fails or the stop button SB31 is turned off, the two output terminals 3-3 and 3-4 of the interlocking unit of the rear-stage equipment are turned off, so that the two input terminals 2-1 and 2-2 of the interlocking unit of the current-stage equipment are turned off, the coil of the current-stage contactor KM21 is powered off, and the current-stage equipment is automatically stopped.
When the contactor KM21 is attracted, the equipment of the current stage is started, the output terminals 2-3 and 2-4 of the interlocking unit are closed and conducted, so that the two input terminals 1-1 and 1-2 of the interlocking unit of the previous stage equipment are communicated, the previous stage equipment can operate in an interlocking operation state, and the interlocking of the previous stage and the next stage is realized.
It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
