Description
Technical field
The utility model relates to a kind of temperature monitoring field, relates in particular to a kind of long-range infrared temperature monitor.
Background technology
At present; Transformer station's electrical equipment heating is comparatively common a kind of irregular operating state; Heating can cause the decline of stable equipment operation property; Serious caused conductor break, fire, various short trouble, thus cause equipment to force power failure, device damage even personal injury etc., cause heavy losses to power system stability operation and people's lives and properties.Because equipment heating receives multiple factor affecting; Increase with conductor surface of contact resistance value and slow or rising rapidly like temperature; Electric current reaches a certain numerical value, and its temperature will rise rapidly etc., and this just requires operation maintenance department to causing heating on the visual plant or having generated heat but continuous monitoring is carried out at not serious position; In time take corresponding measure to temperature variations, avoid having an accident.Therefore, transformer station's electrical equipment being carried out temperature monitoring is the important means that guarantees safety in production.
Transformer station is the unattended method of operation of centralized control basically now, and collection control central station is controlled 4～7 sub-transformer stations of periphery in other words, and the operator on duty generally carries out remote monitoring to the transformer station that is controlled in concentrator station, and the substation is in the unmanned state.Wherein the distance between the transformer station is tens kilometers at most, also has several kilometers at least.Processing to the random fault heat generating spot is that the operator on duty regularly tests with temperature measurer to the heat generating spot scene, often runs tens kilometers back and forth with regard to the personnel of required value class like this and removes thermometric to the scene, not only loses time and the waste of manpower resource.Along with unattended operation transformer station constantly increases, summer the peak hours device context monitoring heat generating spot of sending someone be impossible realize, press for and utilize advanced technological means, cooperate the operation maintenance personnel that the equipment heating point is carried out temperature monitoring work.
The utility model content
The purpose of the utility model provides a kind of long-range infrared temperature monitor, can be transferred to Surveillance center to the real time temperature data of heat generating spot through wireless transport module.
The utility model adopts following technical proposals: a kind of long-range infrared temperature monitor; Comprise infrared temperature collecting unit, CPU, wireless transmission unit and power circuit; The signal output part of infrared temperature collecting unit is connected with the signal input part of CPU, and the communication ends of CPU communicates through wireless transmission unit and Surveillance center.
The signal output part of described CPU also is connected with pushbutton unit.
The signal input part of described CPU is connected with display unit.
Described power circuit comprises AC power circuit and DC power supply circuit.
