Description
Technical field
The utility model relates to electronic technology field, particularly a kind of electrical equipment fire early warning system.
Background technology
The high and low voltage switch cabinet is the visual plant in generating plant, the transformer station, plays a part to open and turn-off power supply, is used for realizing conveying and conversion electric load and withdraws from faulty equipment and circuit from electric system, thereby guarantee safe operation of power system.The high and low voltage switch cabinet is in the long-time running process, and positions such as contact point in the switch cubicle and bus junction are no matter be loosening or old saying all can cause the increase of contact resistance.Because get an electric shock heating, temperature raises and can quicken the oxidation of surface of contact metal again, opens circuit thereby cause, and causes large-area power-cuts.
In recent years; In the generating plant, the device of overheating of electrical accident is owing to take place in the distribution of transformer station and large and medium-sized enterprise and using electricity system; And causing fire and large area blackout to happen occasionally, part also has influence on the normal operation of electric system, even brings about great losses.
The utility model content
The utility model cost is low, fitting operation is simple, can accurately and timely gather and feed back the system of the temperature information of electrical equipment.
To achieve these goals, the utility model provides following technical scheme:
A kind of electrical equipment fire early warning system, it comprises: arm processor, said arm processor signal is connected with light disconnecting relay, GPRS communication interface, display device, DDR and ZigBee wireless communication interface.
Preferably, said arm processor also signal be connected with real-time clock and watchdog module, NandFlash, RS485 interface and SPI Flash.
Through implementing above technical scheme; Has following technique effect: the electrical equipment fire early warning system that the utility model provides; Cost is low, fitting operation is simple, can accurately and timely gather the temperature information of electrical equipment, except can in time temperature and warning information being transferred to the background monitoring system; Can also warning information directly be sent short messages on operation maintenance personnel's the mobile phone, shorten the processing cycle.Ensure the operational efficiency of power equipment, reduced the labour intensity of administrative authority's routine property inspection, reduced job costs, improved task performance, shortened the time of fault judgement and processing, reduced the failure rate of power equipment preferably.
Description of drawings
The structural representation of the electrical equipment fire early warning system that Fig. 1 provides for the utility model embodiment.
Embodiment
In order better to understand the technical scheme of the utility model, describe the embodiment that the utility model provides in detail below in conjunction with accompanying drawing.

In other embodiment; Further, said arm processor 100 is gone back signal and is connected with real-time clock and watchdog module 104, Nand Flash (internal memory of non-linear macroelement pattern) 102, RS485 (a kind of interface of intelligence instrument) interface 106 and SPI Flash (Serial Peripheral Interface internal memory) 103.
The said temperature sensor adopts the wireless temperature measurement sensor, is installed in the contact or the bus junction of isolating switch, and thermometric is not more than 5 minutes at every turn at interval, and stream time is more than 5 years, and the wireless telecommunications frequency of operation is at 2.4GHz or 433MHz.This system can export through GPRS communication interface, RS485 interface and light disconnecting relay through the transmission data of 3,6,9 or 12 wireless temperature measurement sensors of ZigBee wireless communication interface 109 collections, and realization information is transmitted and reported to the police on the spot.Be installed on the background computer, can show the temperature information of all devices point for measuring temperature, demonstrate the warning message of specific fault point in real time.
The electrical equipment fire early warning system of the utility model is installed and used simply, cost is low, adopts the high brightness charactron display interface of high performance processor (as: model is the arm processor of STM32F103), hommization more, general GPRS communication interface and communications protocol, general shell sizes and mounting means easily.Can also possess RS485 interface and GPRS communication interface simultaneously in addition, except can in time temperature and warning information being transferred to the background monitoring system, can also warning information directly be sent short messages on operation maintenance personnel's the mobile phone, shorten the processing cycle.
In addition, gather at the foregoing description, the various storeies that this system has also disposed make information acquisition accurate, and highly-efficient treatment adopts high brightness charactron display interface grouping display mode, makes the value show hommization more.Practicality is extensive, and the output of 3 road light disconnecting relays makes that on-the-spot use is more flexible, adopts the Switching Power Supply of wide input range, imports interchange or the direct current of optional 85V～265V, the various field conditions of flexible adaptation.
More than a kind of electrical equipment fire early warning system that the utility model embodiment is provided carried out detailed introduction; For one of ordinary skill in the art; Thought according to the utility model embodiment; The part that on embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
