Definitions

the invention relates to a circuit breaker for a pump control with a main switch for a pump supplying electrical current to the main circuit, with a flow switch on the pumped by the pump medium line and a sub-switch, which is actuated by the flow switch, the sub-switch part of a electronic control for actuating the main switch is.
Such switching machines are needed in a water network having a memory which is connected to a pump, which promotes water via a line system to a sampling point.
the pump should only be put into operation if water is actually withdrawn at the sampling point.
a flow switch z. B. in the form of a pressure sensor, such as z. B. in the DE 199 08 156 A1 is described, used, which operates in a pressure change, a switching machine that controls a pump that maintains the pressure at the sampling point.
the pressure sensor operates a reed switch in the switchgear, which includes a main switch for closing the circuit for the pump.
the machine contains additional inputs and outputs to control the water extraction system.
the reed contact is thus a secondary switch.
the automatic switcher queries the switching state of the auxiliary switch and opens the main switch, if there are other switching conditions at the inputs.
the invention is based on the task of reducing the power consumption of the switching device in stand-by mode.
the invention provides that the power supply for the controller consists of a switching regulator, which is a buck converter.
a buck converter is an electronic circuit in which the input voltage is reduced as loss-less as possible to a lower output voltage. The power consumption is therefore very low in the idle state (idle).
the actuator is a magnet and the sub-switch is a reed contact.
a pump 3 is connected via a feed line 2, from the output of which a media line 4 extends to a removal point 5.
a flow switch 6 which is set up so that in a media flow in the media line 4 due to the self-adjusting negative pressure, a magnet is moved, with a reed contact 7 is actuated.
the reed contact 7 is part of a switching machine 8, which includes an electronic controller 9 and a main switch 10, wherein the main switch 10 is located in an electrical power supply 11 for the pump 3.
the electronic control unit 9 has further inputs and outputs 12, 13, in particular further states of the media supply system being controlled at the inputs.
the main switch 10 is closed, so that the pump is supplied with current.
the flow monitor no longer responds so that the main switch 10 opens again and the pump 3 is switched off.
a buck converter 15 is provided.
the power consumption of the switch 8 is in standby mode below 500 mA and typically 200 mA.
