In conjunction with Fig. 1, operating principle is described:
1, water level controller: magnetic float, the next pushbutton unit, pushbutton unit brace, magnetic float brace, upper pushbutton unit, waterproof press-button liquid level normally closed switch, waterproof press-button liquid level normal open switch, a water level controller of circular built-in fixed leg composition are installed in 300 * 300 square frameworks;
2, mobile controller: be that 280mm magnetic float, the next pushbutton unit, pushbutton unit brace, magnetic float brace, upper pushbutton unit form an energy and move up and down device according to water level by diameter.
3, circular built-in fixed leg: at water level controller, diameter being installed is the circular built-in fixed leg of 50mm, purpose be control magnetic float, upper (under) position pushbutton unit etc. do not depart from center while moving up and down.Water level controller bottom surrounding is the net form water inlet, prevents that rubbish and toy from entering.
4, above (under) the position pushbutton unit: be designed to elliptical devices, while contacting with waterproof press-button liquid level normally closed (opening) switch in moving up and down process for water level controller, can well press and put in place, guarantee that its contact is good.
5, pushbutton unit brace: after the liquid level normal open switch touches upper pushbutton unit, water level continues in the process of moving up, and can make it keep pinning for a long time the liquid level normal open switch and not unclamp.
6, magnetic float brace: this brace is fixedly connected with magnetic float,, when water level moves up and down, can synchronously promote (under) position pushbutton unit and pushbutton unit brace.
7, liquid level normal open switch: this switch is connected with the 40A ac contactor coil, and when water level controller rises according to water level, magnetic float is because water buoyancy promotes on mobile controller to move to the liquid level normal open switch, make its closure, the energising of 40A ac contactor coil, contactor moving contact closure, submersible pump is started working, as water level descends, mobile controller moves to liquid level normal open switch below, and this switch disconnects, and the 40A ac contactor coil disconnects, the contactor moving contact separates, and submersible pump quits work.
8, waterproof press-button liquid level normally closed switch: this group switch is connected with many group 250A ac contactor coils, during normal operation circumstances, is normally closed, 250A A.C. contactor moving contact closure, low-pressure side user's normal power supply.When water level rises, when the submersible pump displacement still can not meet the switchgear house inflow, this mobile controller will continue to rise, while touching waterproof press-button liquid level normally closed switch, this switch is carried out separating action, make many groups 250A ac contactor coil outage of its series connection, the contactor moving contact separates, and stops power supply in the contactor bottom.Phase fault is caused because of water inlet in assurance fuse bottom.If water level descends in the submersible pump course of work, after mobile controller leaves waterproof press-button liquid level normally closed switch, this switch closure, organizes the energising of 250A ac contactor coil more, contactor moving contact closure, and bottom restores electricity.
In conjunction with Fig. 2, operating principle is described:
Comprise water level controller, the 40A A.C. contactor, minimum one group of 250A A.C. contactor, single-plase submerged pump and RTO fuse form the power distribution room self-draining arrangement, power distribution room 500mm cable trench differs from the 10 ° little slopes of inclining with right side and left side and builds, and dig the 600mm water storage tank at the power distribution room cable trench near under the wall 50mm of left side, cable trench water collecting can be flow in water storage tank by this slope of inclining, place single-plase submerged pump in water storage tank, the anti-rubbish of water storage tank and cable trench Plane Installation falls net, the submersible pump power supply connects through 40A AC contactor touch head system, delivery port is apart from 10cm place, top, power distribution room ground line opening, and sealed hole and processed, being convenient to ponding discharges, dig 400mm and measure the water level water storage tank under low-voltage distribution cabinet left side, from 100mm place at the bottom of measuring the water level water storage tank, water level controller is installed, this controller is square, and use bolt and low-voltage distribution cabinet are fixed, when power distribution room is intake, when the built-in mobile controller of water level controller rises to water storage tank and cable trench isoplanar according to water level, on the built-in mobile controller of water control controller, move, touch the liquid level normal open switch, make its closure, the energising of 40A ac contactor coil, contactor moving contact closure, submersible pump is started working, in water level decline process, during lower than the liquid level normal open switch, this switch separates automatically, and submersible pump quits work.When if water level continues to rise to RTO fuse lower end and low-pressure line-outgoing cable junction 100mm again, move on the built-in float of water level controller and touch waterproof press-button liquid level normally closed switch, and make its separation, by water level controller, connecting, how group 250A contactor coils cut off the power supply, its action is separated, reaching 250A A.C. contactor bottom stops power supply, when water level descends, this waterproof press-button liquid level normally closed switch moves and resets according to the built-in float of water level controller, the action of 250A A.C. contactor is closed, and low-pressure line-outgoing restores electricity.
