Accompanying drawing illustrates:
Fig. 1 is the electrical connection schematic diagram of electric power tunnel drain control unit.
Detailed description of the invention:
Embodiment: see Fig. 1.
Electric power tunnel drain control unit, water pump successively with thermorelay, AC relay normal opened contact, fuse, three
Phase chopper and three phase mains connect, and draw two branches, two branch structures between fuse and AC relay normal opened contact
Become a loop, loop is disposed with fuse, thermorelay, AC relay power up coil, manual explosion-proof normally opened open
Pass, manual explosion-proof normally closed switch, fuse, be provided with contact O between manual explosion-proof normal open switch and manual explosion-proof normally closed switch,
It is provided with contact P between fuse and thermorelay, is connected by wire between contact O and contact P, wire is provided with exchange
Relay normally closed contact and red explosion-proof indicating lamp.
Solid-state relay three, solid-state relay three and positive source and two-way opened it is provided with between contact P and thermorelay
Closing and connect, two-way switch is connected with float and yellow explosion-proof indicating lamp, and red explosion-proof indicating lamp is connected with single-chip microcomputer.
Solid-state relay one, solid-state relay one and single-chip microcomputer control it is provided with between manual explosion-proof normally closed switch and contact O
Normally closed switch processed and power cathode connect, and Single-chip Controlling normally closed switch is connected with positive source.
Manual explosion-proof normal open switch and the normally opened node of AC relay and solid-state relay two parallel join, solid-state relay
Two are connected with green explosion-proof indicating lamp, Single-chip Controlling normal open switch and power cathode, Single-chip Controlling normal open switch and power supply
Positive pole connects, and green explosion-proof indicating lamp powers up coil with AC relay and is connected.
Power supply is 24V power supply, and yellow explosion-proof indicating lamp is 24V direct current lamp, green explosion-proof indicating lamp and the explosion-proof instruction of redness
Lamp is 380V AC Lamp.
During use, after Guan Bi three-phase breaker DK, from one group of alternating current of the biphase proposition of B, C, give through two fuses and control
Part power supply, at this moment, without any action, CM coil is off, and 380V voltage cannot add feed pump, and water pump is not
Starting, simultaneously as normally closed hand switch and single-chip microcomputer normally closed switch are in an ON state, the RED display lamp on panel is rubescent
Light, tells people that now water pump is in stop state.
Assuming that float detects that tunnel is anhydrous, yellow indicator lamp is lighted, although startup water pump button at this moment can be pressed, or
Person's single-chip microcomputer send instruction start water pump all can be not turned on because of float circuit, loop dead electricity and water pump does not rotates.
Assuming that float detects that there is water in tunnel, if our water pump to be started, we can press manual normally opened button QA,
At this moment A.C. contactor adhesive, CC node disconnects, CO node UNICOM, and three-phase alternating current is through element feedwater such as DK, RD, CM, RJ
Pump M powers, and at this moment water pump starts work of drawing water, although at this moment operator unclamps start button QA, because the adhesive of CO node, whole
Individual path is still within conducting state, also has electric current to flow through due to GRD display lamp, now GRD display lamp greening after path setting
Light, and the passage previously set up disconnects due to the disconnection of CC node, red led RED closes, if thermorelay RJ inspection
It is overheated to measure, and crosses stream, overvoltage, lacuna, then it is connected on AC relay and powers up coil and will disconnect, thus A.C. contactor loses
Electricity three group node C disconnects, and makes Pump Failure shut down.Thus being returned to stopped status, green light goes out, when red, the hottest relay
After device RJ detects that loop is replied normally, again press start button QA and just can make starting mode of pump.
The above, be only preferred embodiment of the present utility model, not this utility model is made any in form
Restriction, every according to technical spirit of the present utility model, above example is made any simple modification, equivalent variations with
Modify, all still fall within the range of technical solutions of the utility model.
