Description
Technical field
The present invention relates to a kind of high tension cable connect-disconnect plug operating temperature of internal binding post can monitored in real time,
Belong to field of cable technology.
Background technology
Connect-disconnect plug is the vitals in high-tension line, mainly includes binding post (European terminal), terminal jacket and answers
Power cone, binding post is installed in terminal jacket, high tension cable through after the stress cone in terminal jacket cable aperture with connect
Line terminals is crimped together.If binding post is connected reliably with high tension cable, and terminal screws fastening is normal, then at big electric current
Under duty, the temperature of terminal is normal, does not have abnormal temperature rise.But when binding post connects and loosens, its contact
Resistance will increase, and causing terminal the temperature rise of exception occur when big current work, if processed not in time, may cause fire
Calamity, it is therefore necessary to terminal temperature is monitored.
Traditional terminal temperature monitoring method mainly has two kinds: one is to bind temperature survey and transmission on binding post
Device, wirelessly sends to Surveillance center by temperature signal, and the shortcoming of this method is that error is with seasonal fluctuation, measurement error
Too big, and supporting working battery needs to change for 1 year one, and when changing battery, package unit necessarily be in power down mode, serious shadow
Ring the properly functioning of equipment.Another kind of method is to use remote infrared measurement of temperature method to upload after collecting temperature information, the party
Method is affected relatively big by temperature measuring equipment sensitivity, thermometric distance, and fluctuating error is big, and it is complicated automatically to gather uploading device, cost
Higher.For above-mentioned reasons, existing two kinds of terminal temperature monitoring methods are not all used widely.
Summary of the invention
Present invention aims to the drawback of prior art, it is provided that a kind of high tension cable plug with temp sensing function
Head, to improve the certainty of measurement of terminal temperature, finds accident potential in time.
Problem of the present invention solves with following technical proposals:
A kind of high tension cable connect-disconnect plug with temp sensing function, composition includes binding post, terminal jacket, stress cone
