Anti-jamming circuit is constituted, the interference signal that the sensing of level sensor line is come in is resisted, it is ensured that stable to wait for, it is to avoid misoperation, full electricity
Road is blocking state, and loss due to leakage is minimum, is approximately zero, and waiting water level drops back into water tower or going up to pond makes level sensor switch 20 again
It is secondary to connect, worked next time.
Protected by resistance R9, resistance R10, electric capacity C5, relay DJ coils, triggering pipe B7, triggering pipe B6 and excessively stream electric leakage
Electric leakage of the switch trip coil composition to level sensor switch and wire is protected to monitor；It is intended to improve the reliability of the present apparatus.
When level sensor switch or wire leak resistance are equal to or more than 800K Ω, triggering pipe B6 series connection triggering pipes B7 two
Terminal voltage does not reach triggering pipe turn-on condition；When level sensor switch or wire leak resistance are less than 800K Ω, leakage current is in electricity
Resistance R9 two ends cause boosting, electric capacity C5 chargings are given, when being charged to 66v（Trigger conducting voltage 33v+33v=66v of pipe）Trigger Guan Yin
It is triggered and is mutated conducting, the electric energy on electric capacity C5 is discharged back by relay DJ coils to triggering pipe B7 to triggering pipe B6 formation
Road, closes relay DJ normal open switch point, and at the same time L lines are to resistance R2 to rectifying tube D5 to relay DJ coils to relay
Device normal open switch point is to excessively stream earth leakage circuit-breaker interior loop KJ to resistance R10 to rectifying tube D2 to the loop of resistance R1 to N lines
Electric current passes through immediately, not only maintains relay DJ conducting, also drives the dropout of excessively stream earth leakage circuit-breaker, disconnects general supply.
The present apparatus is applied to well, the water level in pond, only another joint need to be selected on level sensor switch 20, water
Two water level nodes that position sensitive switch 20 is put into debugging control in well, pond can be achieved to control well, water level in water pool；
The present apparatus changes wiring and can be used to work in three-phase alternating current pipeline equipment accordingly.
The design focal point of the present invention is：According to human body safe current 30mA, safe voltage 36V condition contracting is born
As low as human body unaware scope, the current value for calculating the level sensor switch of the present apparatus is design considerations, is released using energy storage is integrated
Put, then integrate the low current conversion high current of delay release, have the mode that more low current discharges again, using FET and triggering
Pipe DB3 and electric capacity C2, resistance R7 constitute triggering and conducting holding circuit, make resistance in opposite sets bigger, in selection 2.2M Ω
Resistance is as two sensing lines to external resistance, and the current value for switching the level sensor of the present apparatus is smaller, that is, meeting safety will
