Both ends are connected in parallel between the first pin of magnetic starter and second pin, and the both ends of relay J2 are connected in parallel on magnetic starter
Between second pin and the 9th pin.
As shown in Fig. 2, connection switch CB1 between the 4th pin of magnetic starter and the 7th pin, works as magnetic starter
Interior electronic protector is completed the short circuit loaded to major loop, overload, disconnected phase and earth leakage search/lockout and is detected, and normal operating conditions is in
When, protector internal relay is attracted, and CB1 closure, the 4th pin and the 7th pin are connected, and two-way switch NK, which works as, gets to remote control shape
When state, the course of work of this system is as follows：
1) if water level in water pool is lower than the probe B point of lower limit water level sensor, the probe C of electrode B and third water level sensor
Conducting is not turned on, triode VT1 and three poles between the probe A of upper limit water level sensor and the probe C of third water level sensor
Pipe VT2, triode VT3 and triode VT4 cannot get bias current, and be in off state.Relay J1 and relay J2 are failure to actuate.
2) when water level in water pool rises to the probe B point of lower limit water level sensor, but the probe A of upper limit water level sensor is not arrived
When point, triode VT3 and triode VT4 are connected by self-supporting bias current, relay J2 energized action, normally opened contact closure,
The line short circuit that control in 3 control loop of magnetic starter between second pin and the 9th pin stops.At this time 1 pin, 2 pins and
It all cannot be with 36V electric power generating composition circuit between 9 pins.So water pump 2 is inactive.
3) when the probe A of upper limit water level sensor point, triode VT1 and triode VT2 are connected by self-supporting bias current,
The normally opened contact of relay J1 movement, relay J1 is closed, and the first pin and the 9th in the control loop of magnetic starter 3 draws
The line conduction of control starting between foot, thus the power supply of the A.C. contactor CJ coil in 3 control loop of magnetic starter is connected,
It is allowed to work, the normally opened contact closure of the A.C. contactor CKJ in major loop；Meanwhile the auxiliary contact of A.C. contactor
CJ1-3 is closed at, and self-insurance.Water pump 2, which is started to work, to be drained.Due to intermediate relay KA coil always it is electric, so exchange
The coil of contactor CJ always it is electric, the auxiliary contact CJ1-3 of A.C. contactor is constantly in closed state, until relay J2
Normally opened contact open position.
4) it is pumped with continuous, water level decreasing, as long as the probe B point of lower limit water level sensor is also in the water surface hereinafter, water
Pump 2 will continue to operate, until triode VT3 and triode VT4 are obtained not when water level is lower than the probe B point of lower limit water level sensor
To bias current, and cut-off is forced, therefore relay J2 power loss, normally opened contact disconnect, in 3 control loop of magnetic starter, second draws
The route that control between foot and the 9th pin stops disconnects, i.e., the major loop A.C. contactor CJ coil losing electricity of water pump 2, water pump 2 stop
Only work.
5) when the secondary rising of water level in pond, when the water surface is shown to the probe B point for reaching lower limit water level sensor, at this moment water
Pump 2 does not work, and the control in 3 control loop of magnetic starter between second pin and the 9th pin is only stopped to the short circuit of route
It is logical, it when water pump 2 reaches the probe A of upper limit water level sensor, is again turned on water pump 2 and is drained, until the near lower limit of water level
The probe B point of water level sensor is hereinafter, water pump 2 just stops working.
The drainage system is transformed by following material：It is waste and old using the power module of belt conveyer comprehensive protector and two
Electric pole type coal site sensor electronic circuit board, retain original intrinsic safety characteristic and flameproof enclosure.It saves well in this way
Resource.Magnetic starter is controlled using the logical relation of high and low water level and 2 operating status of water pump by reservoir fluid change
3 open, stop operating status.
The above is only the preferred embodiments of the invention, are not intended to limit the invention creation, all in the present invention
Made any modifications, equivalent replacements, and improvements etc., should be included in the guarantor of the invention within the spirit and principle of creation
Within the scope of shield.
