Preferably, the elbow-type end insulating plug includes cock body and lid, the cock body is in round table-like, the thermometric
Probe, which is filled out, to be located in described cock body, the structure that the temperature probe, cock body and lid three are formed in one.
Preferably, the surface of the lid is fixed with the hexagonal handle of a rotation.The utility model in this way,
Directly it can be filled in using the hexagonal handle of rotation by the elbow-type end insulating plug rotation provided with temperature probe is filled out reasonable
Position.
Preferably, the temperature-measuring optical fiber is equipped with an optical fiber on the position of elbow-type end insulating plug fixes guarantor
Pillar, the temperature-measuring optical fiber run through elbow-type end insulating plug after fixing protection pipe through optical fiber.In this way, it ensure that thermometric
Optical fiber can have enough securities.
Preferably, the temperature measurer body is digital phosphor optic fiber thermometer.Can digitize intuitively show it is each
Temperature inside end.Can be in time to the ring main unit interval interruption maintenance of temperature anomaly.Cable network operation people can be reduced
Member.
Substantial effect of the present utility model is：The utility model is utilized under fluorescence temperature probe different temperatures to low-tension pulse
Rush the obstructed of wave reflection time, temperature, by the way that fluorescence temperature probe is poured in all insulation, tangible formula elbow-type end
Inside insulating plug, it is integrally formed, the internal temperature of elbow-type end can be detected.Actual use has following advantage：Can be with
Actually measure all insulation, tangible formula elbow-type end inside actual temperature.Can not be in cable elbow-shaped head before solving
The problem of portion's actual temperature is controlled；Solve the problems, such as accurately understand partial discharge situation inside cable elbow-shaped head；Solves electricity
Cable network operation personnel lack the problem of O＆M, monitoring means.
