Abstract
Water heater water-shortage protection device of the present invention is the protector for electric water heater according to railroad coach electric heater professional standard development; including power supply, level electrode, protection switch, controller; level electrode is according to water level control protection switch break-make power supply; controller controls the on/off time; power supply is automatically cut off when being lacked inside electric heater, not heated condition is remained powered off in the case of no water supply or water shortage.After certain water level is added water to, automatic heating.
Description
Technical field
The present invention relates to a kind of water heater water-shortage protection device, is applied particularly in railway, civilian electric heater.
Background technology
With market economic development, electric heater railway efficiency, it is daily it is civilian in it is more next popularize, but in electric heater
It can often occur to cause water heater to damage because of water shortage in use, influence using effect, easily cause potential safety hazard, can also be made because of electric leakage
Into Danger Electric shock risk source；And easy scaliness in water tank, cleaning are inconvenient.
The content of the invention
The technical problem to be solved by the invention is to provide a kind of water heater water-shortage protection device, add automatically in water shortage
Water, auto water stopping when water is full, is ensured personal safety, and improves safety coefficient, and clear up conveniently.
The water heater water-shortage protection device of the present invention, including the power supply of electric power, the level electrode of sensed water level, control are provided
The protection switch of power switch, the controller for controlling the on/off time, it is characterised in that：Level electrode is protected according to water level control
Protect switch on and off power supply, controller control on/off time；
Power supply is DC110V power supplys, regardless of both positive and negative polarity；
For level electrode when being emptied again after water tank fills water, two interelectrode insulating resistance values are no less than 300K Ω；
Protection switch is anti-dry heating temperature controller switch or flow control switch；
In the control loop of controller incoming transport contactor coil, the Push And Release of A.C. contactor is controlled；
Panel is provided with water level indicator light, power supply indicator.
Water heater water-shortage protection device of the present invention is the electric heater according to railroad coach electric heater professional standard development
Protector, including power supply, level electrode, protection switch, controller, level electrode is according to water level control protection switch power on/off
Source, the controller control on/off time, power supply is automatically cut off when being lacked inside electric heater, in no water supply or the feelings of water shortage
Not heated condition is remained powered off under condition.After certain water level is added water to, automatic heating.
Brief description of the drawings
Fig. 1 is the water heater water-shortage protection device schematic diagram of the embodiment of the present invention.
Embodiment
A kind of water heater water-shortage protection device as shown in the figure, including the level electrode of the power supply of offer electric power, sensed water level,
Control the protection switch of power switch, control the controller of on/off time, level electrode is according to water level control protection switch
Break-make power supply, controller control on/off time；Power supply is DC110V power supplys, regardless of both positive and negative polarity；Level electrode is noted in water tank
When being emptied again after full water, two interelectrode insulating resistance values are no less than 300K Ω；Protection switch switchs for anti-dry heating temperature controller
Or flow control switch；In the control loop of controller incoming transport contactor coil, the Push And Release of A.C. contactor is controlled；Face
Plate is provided with water level indicator light, power supply indicator.
The water heater water-shortage protection device of the present embodiment, power supply connect DC110V power supplys, regardless of just by 1~2 pin power input
Negative pole；Water level signal is inputted by 3~4 pin water level signals, and 3~4 pin connect level electrode；Temperature controller switch is connect dry anti-dry by 5~6 pin
Temperature controller switch or flow control switch are burnt, does not have to anti-dry heating temperature controller such as or flow controls, by 5~6 pin short circuits；7~8 pin connect
Controller switches, in the control loop of controller incoming transport contactor coil, control the Push And Release of A.C. contactor；9~10
External control cabinet panel DC12V water shortage indicator lamps, 9 pin are positive pole.
Level electrode will keep good conductive characteristic.To be cleared up within every two to three months, remove electrode surface dirt,
To keep good electric conductivity；Level electrode when being emptied again after water tank fills water, should not by two interelectrode insulating resistance values
Less than 300K Ω；
Yellow light-emitting diode is power supply instruction, shows there is power supply supply when bright；
Red light emitting diodes indicate for water shortage, show that water tank lacks water or level electrode have dirt when bright, should immediately treat；
Green LED indicates for heating, shows heating water tanks when bright.
Water heater water-shortage protection device of the present invention is the electric heater according to railroad coach electric heater professional standard development
Protector, including power supply, level electrode, protection switch, controller, level electrode is according to water level control protection switch power on/off
Source, the controller control on/off time, power supply is automatically cut off when being lacked inside electric heater, in no water supply or the feelings of water shortage
Not heated condition is remained powered off under condition.After certain water level is added water to, automatic heating.
