Abstract
The utility model provides a control system for accurately monitoring the temperature of power distribution cabinets in real time. The control system comprises a PLC, wherein the PLC is connected with a power distribution cabinet power supply by a control switch; optical fiber probes for detecting the temperature information of the power distribution cabinets are uniformly distributed inside the power distribution cabinets, and the optical fiber probes in each power distribution cabinet are connected to an optical separator mounted on the power distribution cabinet; the optical separators of multiple power distribution cabinets are connected to a wiring box by optical fibers; the wiring box is connected to an optical analyzer for analyzing temperature values measured by the optical fiber probes; and the optical analyzer is connected to the PLC. Further, the PLC is also in control connection with a hand-operated touch display screen for displaying the power distribution cabinet temperature information and performing control operation. Further more, the PLC is connected with an acousto-optic alarm which is used for giving an alarm when the temperature value exceeds a preset warning value.
Description
Technical field
The utility model relates to the power distribution cabinet field, specifically is applied to the monitoring temperature of power distribution cabinet.
Background technology
in the power distribution cabinet field, interior a large amount of connectors and the various electronic devices and components installed due to power distribution cabinet, and the existence of a large amount of wires is arranged, cause the total resistance value of power distribution cabinet very high, therefore directly cause power distribution cabinet in work, namely in the situation that conduction can be distributed a large amount of heats, temperature in power distribution cabinet is improved suddenly, again because electronic devices and components and the connector of power distribution cabinet inside are very high to the dustproof requirement of power distribution cabinet, therefore power distribution cabinet all adopts sealed type, reducing dust enters in power distribution cabinet, will make so the very difficult discharge power distribution cabinet of heat of the generation in high-low voltage electric power distribution cabinet, too high temperature can affect the work of power distribution cabinet and use, that is to say, must carry out the monitoring temperature of power distribution cabinet, should immediately cut off the power supply when temperature raises.
The utility model content
The utility model provides a kind of and can accurately monitor in real time the control system of power distribution cabinet temperature for above-mentioned the deficiencies in the prior art.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of power distribution cabinet control system, comprise the PLC controller, the PLC controller be connected with the power distribution cabinet power supply by control switch; Be evenly arranged in power distribution cabinet inside for detection of the fibre-optical probe of temperature information in each power distribution cabinet, each power distribution cabinet inner fiber probe all is connected on the light separator of installing on power distribution cabinet; The light separator of a plurality of power distribution cabinets is connected to terminal box by optical fiber;
Above-mentioned terminal box is connected to the light analyzer for analytical calculation fibre-optical probe measured temperature value; Described smooth analyzer control connection is to the PLC controller.
Be further: above-mentioned PLC controller is gone back simultaneously control connection and is useful on the manual touch display screen that shows the power distribution cabinet temperature information and carry out control operation.
Be further: above-mentioned PLC controller also is connected with the audible-visual annunciator of reporting to the police simultaneously when temperature value exceeds the setting alarming value.
The beneficial effects of the utility model are:
The utility model power distribution cabinet control system, by the fibre-optical probe of efficient thermometric is installed in power distribution cabinet, then by temperature information is carried out analytical calculation with the light analyzer, the actual temp value shows by the display screen that the PLC controller connects, can also carry out high temperature alarm by audible-visual annunciator; When high temperature, the PLC controller directly disconnects the power supply of power distribution cabinet.
Description of drawings
Accompanying drawing is system architecture diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described:
As shown in drawings, it shows an embodiment of the present utility model, and the utility model power distribution cabinet control system comprises the PLC controller, the PLC controller be connected with the power distribution cabinet power supply by control switch; Be evenly arranged in power distribution cabinet inside for detection of the fibre-optical probe of temperature information in each power distribution cabinet, each power distribution cabinet inner fiber probe all is connected on the light separator of installing on power distribution cabinet; The light separator of a plurality of power distribution cabinets is connected to terminal box by optical fiber;
Above-mentioned terminal box is connected to the light analyzer for analytical calculation fibre-optical probe measured temperature value; Described smooth analyzer control connection is to the PLC controller.
Above-mentioned PLC controller is gone back simultaneously control connection and is useful on the manual touch display screen that shows the power distribution cabinet temperature information and carry out control operation.
Above-mentioned PLC controller also is connected with the audible-visual annunciator of reporting to the police simultaneously when temperature value exceeds the setting alarming value.
The above has done detailed description to the utility model preferred implementation by reference to the accompanying drawings, but the utility model is not limited to above-mentioned execution mode, in the ken that those of ordinary skills possess, can also make a variety of changes under the prerequisite that does not break away from the utility model aim.
