A kind of cable tunnel self-draining arrangement, including Level monitor, water level control intermediate relay, the main friendship of motor
Contactor and immersible pump are flowed, Level monitor monitoring tunnel water level, when reaching warning line, triggers relay among water level control
Device, makes the main A.C. contactor closure of motor, and the corresponding immersible pump of the main A.C. contactor of motor is opened.The Level monitor is
Ball float water level monitoring device.The water level control intermediate relay has been correspondingly arranged two groups of main A.C. contactors of motor, two groups of electricity
Owner's A.C. contactor is switched by switching switch SA, and two groups of main A.C. contactors of motor correspond to one group of immersible pump respectively.It is described
Self-draining arrangement further includes warning system, and the warning system includes substation, and the substation includes cable duct water inlet and accuses
Alarm device, the public observing and controlling screen of substation, complex automatic system and supervisory control of substation microcomputer, cable duct water inlet alarm device pass through
The public observing and controlling screen of substation is connected to complex automatic system, supervisory control of substation microcomputer connection complex automatic system.The electricity
Cable ditch water inlet alarm device includes immersible pump priming level magnetic reed switch and cable duct bottom magnetic reed switch, magnetic reed switch are connected to
The public observing and controlling screen of substation.The warning system further includes concentrator station, and concentrator station includes front-end system, master server and the first
Machine work station, front-end system connection comprehensive automation system of transformer substation, front-end system are connected to the first man-machine work by server
Stand.The warning system further includes regulation and control center, and regulation and control center includes front server, SCADA servers, the second man-machine work
Stand and history server, front server connection comprehensive automation system of transformer substation, front server pass through SCADA servers
The second man-machine work station and history server is connected respectively.
Cable tunnel self-draining arrangement provided by the invention include water level control system and and warning system, water level control
System is according to water level control principle, the water level using ballottement by ponding, and water level control system links with water pump, and water level reaches one
During definite value, starting mode of pump, ponding is proposed to drain into the municipal rainwater pipeline near tunnel.
As shown in Figure 1, be the circuit structure diagram of automatic drain system of the present invention, SA is water pump switching switch, Auto-drainage
System uses 4 work water pumps, wherein two uses, two spare, and pump house drainpipe is pressed using the form of two water level lines
Water bunker level is divided according to direction from the bottom up, is respectively water level 1 and water level 2, drainage system is according to liquid level signal control
Level relay processed, so as to control the quantity of start and stop and the start and stop of water pump.
KM is the main A.C. contactor of motor, and KA is water level control intermediate relay, when KM1 branches are connected in SA selections, works as tunnel
When road water level is increased to setting position, priming level relay KA, KA closure, main A.C. contactor KM1 or KM2 are attracted, KM1
Branch or the corresponding motor for submerged pump of KM2 branches start, and when water level is down to setting water level, KA releases, KM1 or KM2 are solved
Lock, immersible pump stop pumping.Wherein, 1HL is power supply indicator, and 2HL is water pump operation indicator light, and 3HL is overload light.
The water level control system of the present invention includes two water-level control circuits as shown in Figure 1, illustrated in Fig. 1 KM1 and
The operation circuit of water level 1 corresponding to KM2,2 same Fig. 1 of corresponding circuits figure of water level, by varying floating ball and circuit connecting contacts
Highly, the position of water level 2 is adjusted, water level 2 corresponds to the main A.C. contactor of KM3 and KM4 motors.
Water level alarm signal hop is designed using buoyancy magnetic method, and cable duct is intake and diving pump activation signal returns
Comprehensive automation system of transformer substation is accessed on road, as shown in Fig. 2, cable duct water inlet alarm device is equipped with immersible pump priming level magnetic red
