Description
Technical field
The present invention relates to the field of electronic product, particularly relate to a kind of photoelectric sensor.
Background technology
Along with the increase day by day of social power consumption, the electrical load of high voltage electric equipment as transformer, mutual inductor, high-tension switch cabinet, disconnecting link etc. that carry large electricity conveying task is also increasing sharply.Tie point in electrical network between numerous high voltage electric equipment itself and equipment is electric power conveying weakest link, and this weak link is interface heating (position such as contact and bus bar junction) mainly.Along with the increase of load, cause tie point to generate heat and form vicious cycle: temperature rise, expansion, contraction, oxidation, resistance increases, heats up once again, finally leads to a disaster.The domestic method generally used the temperature survey of electrical equipment high pressure tie point is for regularly using infrared thermometer pointwise thermometric at present.Adopt the method for infrared thermometer pointwise thermometric must avoid again the interference of sunray, measuring error is comparatively large, and needs a large amount of manpower and materials.And this method also the cycle longer, the probability broken down because of undetected is very large.The isolating switch of the handcart switch cabinet inside after current update, the position of the equipment such as disconnecting link and dynamic/static contact are hidden, and infrared thermometer cannot manually have been patrolled thermometric.Generate heat to having an accident from high-tension apparatus and need through after a while, can accomplish completely note abnormalities early and prevent, the generation of prevention electric power accident, therefore imperative to operation high voltage electric equipment temperature real time on-line monitoring.
Summary of the invention
The technical matters that the present invention mainly solves is to provide a kind of photoelectric sensor, temperature measurement accuracy is high, little, the easy installation of fast response time, volume, monitor in real time, strong interference immunity, and measuring tempeature is not by the impact of external temperature, measuring accuracy obtains effective guarantee, and saves a large amount of human and material resources.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of photoelectric sensor, comprise probe, temperature sensing pipe, web member, radiation proof baffle plate, hygrosensor and Displaying Meter, described probe is connected with temperature sensing pipe, described temperature sensing pipe is connected with hygrosensor by web member, described radiation proof baffle plate is arranged on the junction of temperature sensing pipe and web member, and described Displaying Meter is connected to one end of hygrosensor.
