Utilize the utility model discloses a cable temperature sensor that cable junction terminal temperature sensor solved the use of traditional means adopts platinum resistance etc. More, overall structure is more complicated, need external changer, and the cable is arranged in the cable pit usually, lead to above -mentioned mode wiring installation difficulty, and the cable pit is often intake, this type of sensor chang youyu seals up the easy short circuit of problem, it is inaccurate to cause the temperature to detect, the reliability is low, the precision is not high, cost and consumption are high, and inconvenient installation, the unable reliable technological problem who gathers.
Description
Technical field
This utility model is related to a kind of temperature sensor, more particularly, to a kind of cable connecting terminals temperature sensor, belongs to
Power equipment connector temperature monitors field.
Background technology
With use in electric power system for the aluminium alloy cable, copper-aluminium transition connection terminal is also widely applied, copper aluminum mistake
Cross connection terminal to generate heat due to the factor such as electricity consumption overload, aging or contact resistance be excessive, cause temperature to raise, lead to connect
Terminal deforms, and then affects the mechanically and electrically performance of connection terminal, may result in cable connector to explode, causes cable fire, from
And jeopardize safe operation of electric network.Therefore, the temperature for cable connecting terminals is continuously monitored, for judging connection terminal
Whether it is in normal condition, prevention line fault has larger help.Adopting platinum the cable temperature sensor that traditional means use more
Resistance etc., overall structure is more complicated, needs external transmitter, and cable is typically deployed in cable duct, leads to aforesaid way cloth
Line installation difficulty, and cable duct often intakes, such sensor, often because sealing problem is easily short-circuit, causes temperature detection to be forbidden
Really, reliability is low, precision is not high, cost and power consumption are high, and is inconvenient to install, and the temperature of copper-aluminium transition connection terminal is carried out soon
Speed, reliable collection are current technology difficult problems.
Content of the invention
The technical problems to be solved in the utility model is to provide a kind of cable connecting terminals temperature sensor, using this practicality
Adopting platinum resistance the cable temperature sensor that a kind of new cable connecting terminals temperature sensor solution traditional means use more
Deng overall structure is more complicated, needs external transmitter, and cable is typically deployed in cable duct, leads to aforesaid way wiring peace
Dress is difficult, and cable duct is often intake, such sensor often because sealing problem is easily short-circuit, cause temperature detection inaccurate,
Reliability is low, precision is not high, cost and power consumption are high, and is inconvenient to install the technical barrier it is impossible to reliably gather.
The technological means that this utility model adopts are to provide a kind of cable connecting terminals temperature sensor, including shell, sense
Warm element, shielded cable and magnet ring, described temperature-sensing element is encapsulated in shell；Temperature-sensing element is connected with shielded cable；Shielding
Cable jacket magnet ring.
Described shell 1 is metal circular tube.
Described shielded cable 3 is three-core shielding cable.
Described temperature-sensing element 2 is digital.
The technical scheme being provided using this utility model, temperature-sensing element is encapsulated in shell, temperature sensor real-time detection
The temperature of connection terminal, temperature signal can intuitively show surveyed cable connecting terminals temperature after shielded cable and magnet ring
Degree, you can complete the temperature monitoring to cable connecting terminals.
Shell is done using metal circular tube there is Thermal conductivity and decay resistance, and waterproof.
Reduce the error rate of data transfer, sensor and three-core shielding cable connection using three-core shielding cable and magnet ring,
By epoxy sealing it is ensured that the accuracy of temperature detection and waterproof.For to aluminium alloy cable copper-aluminium transition connection end
The working condition of son is monitored, and has that structure is simple, monitoring accuracy is high, easy for installation, low cost and other advantages.
Using temperature-sensing element 2 be digital, power consumption is relatively low, high precision.
Using the technical solution of the utility model completely can with traditional means use cable temperature sensor more adopt platinum
Resistance etc., overall structure is more complicated, needs external transmitter, and cable is typically deployed in cable duct, leads to aforesaid way cloth
Line installation difficulty, and cable duct often intakes, such sensor, often because sealing problem is easily short-circuit, causes temperature detection to be forbidden
Really, reliability is low, precision is not high, cost and power consumption are high, and is inconvenient to install the technical barrier it is impossible to reliably gather.
Brief description
Fig. 1 is system architecture diagram of the present utility model；
In figure is labeled as：1st, shell, 2, temperature-sensing element, 3, shielded cable, 4, magnet ring.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment is described further to utility model.
Shown in Fig. 1, a kind of cable connecting terminals temperature sensor, including shell 1, temperature-sensing element 2, shielded cable 3 and magnetic
Ring 4, temperature-sensing element 2 is encapsulated in shell 1；Temperature-sensing element 2 is connected with shielded cable 3；Shielded cable 3 overcoat magnet ring 4.
During test, three-core shielding cable is connected by soldering mode with temperature-sensing element, shell using waterproof, anticorrosion, lead
Hot good metal cylinder, by epoxy sealing；The external magnet ring of three-core shielding cable；Temperature-sensing element senses for digital quantity
Device, temperature-sensing element 2 is encapsulated in shell 1, and temperature-sensing element 2 is connected with shielded cable 3；Sensor 2 is in close contact with shell 1.
Above-mentioned cable connecting terminals temperature sensor is arranged at cable connecting terminal, temperature sensor can be examined in real time
Survey the temperature of connection terminal, temperature signal can intuitively show surveyed cable connecting terminals temperature after shielded cable and magnet ring
Degree, and high precision.
