background technology:
Surge protector (SPD) is indispensable a kind of device in electronic equipment lightning protection; its effect is scurrying into line of electric force, in the instantaneous overvoltage of signal transmssion line is limited in equipment or system can bear voltage range; or powerful lightning current earial drainage is entered ground, protect protected equipment or system to exempt from the infringement of LEMP or switching overvoltage.
MOV is the core devices of voltage-limit type SPD.Voltage-limit type SPD there will be constant temperature and rises in various non-normal working situation, causes SPD fault after causing MOV thermal runaway, and meeting initiation fire accident time serious, the real-time monitoring therefore for its temperature has great importance.
Theoretical according to Ion transfer, MOV in long-term operation because it is constantly subject to the continuous action of power current and dash current, cause the resistive reduction of MOV, thus cause the reduction of its pressure sensitive voltage, and cause the continuous increase of leakage current and the rising of surface temperature.Because each MOV degree of aging being in parallel connection is different, therefore also there is very big-difference in the surface temperature of each MOV, especially arrived aging deterioration later stage nearly all heat and be all gathered on the comparatively serious MOV of degree of aging.Therefore the degree of aging of its cooperation situation and SPD entirety can be judged by the surface temperature of each MOV of contrast.
A wireless transmitter module is increased in surge protector; this wireless transmitter module is used for the operating temperature data of surge protector to gather; and the data wireless collected is transferred to wireless receiving module, thus realize monitoring constantly surge protector working temperature.And certain warning or disjunction threshold value can be set, realize tripping protection.
Current surge protector only has lightning protection function, and temperature when can not monitor its work constantly.Therefore be necessary to design the surge protector with real-time radio monitoring temperature.Patented claim, temperature sensor is directly connected with wire with microprocessor by a kind of intelligent surge protector (201020674361) with monitoring temperature, and the time one is long, and wire is aging, and measuring system stability will be caused not high.Patented claim; the on-Line Monitor Device (200920097619.3) of Surge Protector accepts SPD by optical sensor and carries out identifying at surge current or luminous device sends under self deterioration, damaged condition light signal and judge; but this Patent Office is by force sex-limited; because existing market only has the relatively poor MOV of quality just to blast luminescence suffering thunderbolt, the light signal that thunder and lightning produces simultaneously also can disturb efficiency and the accuracy of its on-line monitoring.
summary of the invention:
