Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the circuit diagram of the utility model temperature detection branch road;
Fig. 3 is the circuit diagram of the utility model voltage detecting branch road.
Wherein, 1-Power Entry Module, 2-power source protective module, 3-detects control module, 4-Executive Module, 5-output module.
Embodiment
Below in conjunction with accompanying drawing, further describe the technical solution of the utility model, but described in claimed scope is not limited to.
As Fig. 1; the controllable electric power power distribution cabinet with monitoring function; it comprises Power Entry Module 1, power source protective module 2, Executive Module 4 and the output module 5 connecting successively; in Executive Module 4, be provided with relay; it also comprises the detection control module 3 being connected between power source protective module 2 and Executive Module 4; detect in control module 3 and be provided with testing circuit, testing circuit is combined by one or more of temperature detection branch road, current detecting branch road or voltage detecting branch road.
Described Power Entry Module 1 comprises the connector of various models, receives the multiple power sources inputs such as 12V, 28V or 270V; Power source protective module 2 is the electric elements such as circuit breaker, fuse; Executive Module 4 is various relay groups; Output module 5 is also connector group, and output interface can be the plurality of devices such as blower fan, valve, motor power supply is provided.
As Fig. 2, in described temperature detection branch road, be provided with temperature sensor, the output of temperature sensor is connected with the connector of output module 5, and the temperature value that described temperature sensor detects is delivered to host computer with the form of 485 signals.
When host computer is judged circuit abnormality by the electric current, the voltage signal that collect, or while monitoring in power distribution cabinet temperature anomaly, host computer can be by corresponding relay coil negativing ending grounding is disconnected power consumption equipment, thereby avoid the damage of power consumption equipment or affect the operation of system other parts.
As Fig. 3, in described voltage detecting branch road, be provided with voltage sensor, the output of voltage sensor is connected with the connector of output module 5, and described power supply is input as 270Vd.c., the anode of power supply is connected to after fuse on the contact of relay.The positive pole of relay coil is received 28V anode, utilizes input interface connector input control signal, the break-make of control relay coil negative pole and 28V negative terminal, thus the action of control relay contact realizes energising and the power-off of power consumption equipment then.Relay status feedback signal adopts light-coupled isolation output, and feedback signal can be delivered to host computer by output interface connector.Between relay contact output and power supply negative terminal, a voltage sensor in parallel, realizes the function that Real-Time Monitoring is carried in power consumption equipment both end voltage.The wire picking out from relay contact is passed current sensor, then receive the output interface connector of power consumption equipment anode, thereby realize the measuring ability of power consumption equipment size of current.
In described current detecting branch road, be provided with current sensor, the output of current sensor is connected with the connector of output module 5.
