The multi-point temperature sensor is encapsulated in the temperature measuring cable with reasonable space, and temperature data of each point is transmitted to an intelligent temperature collector through a transmission bus in digital mode.
Description
Technical field
The utility model relates to a kind of cable with real-time temp sensing function.
Background technology
Cable is widely used in the electric power system of electric power enterprise and industrial and mining enterprises as the passage of power delivery and information exchange.Wherein the high-voltage power cable long-time running can cause that temperature is too high under high voltage, big electric current environment, occurs unusual; Perhaps raise owing to excess load, contact resistance cause temperature greatly, perhaps owing to reasons such as manufacturing cable head technology and the quality of cable own, the insulation weak part is easily breakdown under system's over-voltage condition, and temperature is sharply raise, thereby causes blast to cause fire.
In recent years, at above-mentioned these situations, many enterprises have all developed on-line monitoring system of electric power cable, real-time monitoring power cable operating temperature and variation tendency thereof, can in time report to the police when out-of-limit or temperature rise speed is out-of-limit in temperature, and point out the heat generating spot position, the operations staff is in time handled, thereby guarantee cable running safety.
Usually, the power cable on-line monitoring system adopts the distributed on line monitoring system, intelligent temperature collector and digital sensor are positioned at the cable trough scene, Temperature sampler is one of nucleus equipment of system, digital sensor is distributed on the temperature high-tension cable to be measured by certain distance, and connect with bus mode, intelligent collector is laid in place, accept the digital temperature signal that the thermometric bus transmits in real time, the digital signal after will handling simultaneously is sent on the supervisory control comuter that is positioned at the control room.Site intelligent collector, digital sensor, communication bus, supervisory control comuter form distributed online temperature alarming system.As scheming: because temperature sensor adopts the monobus connected mode, be articulated on the monobus network, lay, be connected with data acquisition module more together with the power cable colligation by a plurality of digital temperature sensors.Connection, the power line etc. in addition set up simultaneously.Because the region is narrow and small in the cable trough, cable is many, cause many cables to be stacked together, it is abominable to lay environment, certain transducer broken string in the running often occurs, come off, perhaps because the interior ponding of cable trough makes transducer and joint component whom be soaked damage by, cause part signal not upload, monitoring system can not normally be moved.This situation is present in the power cable monitoring system of industrial and mining enterprises commonplacely.
Summary of the invention
The purpose of this utility model is exactly the deficiency that exists at above-mentioned prior art, providing a kind of can together lay cable for measuring temperature with power cable, have waterproof simultaneously, stretching resistance is strong, the cable with real-time temp sensing function of complete function of collection thermometric, communication and one.。
The purpose of this utility model is achieved through the following technical solutions.
A kind of cable with real-time temp sensing function, it is characterized in that this cable comprise tubulose insulated cable cortex and be positioned at the pipe type cable cortex be arranged at intervals with digital temperature sensor, telecommunication cable, power line, reinforcement wire.
A kind of cable of the present utility model with real-time temp sensing function, temperature transducer is connected the back, is in the same place with power line and reinforcement steel wire plying with order wire, penetrate insulated tube or encapsulate, become temperature transducer is packaged in cable in the cable core with sealed insulating material.
Cable of the present utility model at most only needs 3 leads can connect a plurality of temperature sensors.The most succinct structure is to utilize the numeric type transducer can be by the characteristics of data wire power supply, in cable for measuring temperature, can place two parallel finer wires and can connect much 200 temperature sensors, so not only make the manufacturing of cable for measuring temperature easy, cost descends, and improved cable for measuring temperature tensile strength, be convenient to the replacing of temperature sensor, make that the temperature control system that adopts temperature sensor more is applicable to badly, the complicated applied environment of site contour.
Cable of the present utility model has stronger stretching resistance and capacity of heat transmission preferably, and in cable for measuring temperature, the each point temperature data is sent to the intelligent temperature collector by a transfer bus with digital form to the multi-point temp transducer by rational pitch packages.

Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A sectional drawing of Fig. 1.
Fig. 3 is the B-B sectional drawing of Fig. 1.
Embodiment
A kind of cable with real-time temp sensing function, this cable comprise tubulose insulated cable cortex 1 and are positioned at the telecommunication cable that is arranged at intervals with digital temperature sensor 63 of pipe type cable cortex, power line 4, reinforcement wire 2,5.
Embodiment
With (BHT-9005) digital temperature sensor, telecommunication cable, power line 4, wire, wrap winding with the sealing of (silicon rubber) insulating material.
Technical indicator:
Measure error: 0.5 ℃ of lasting accuracy: 0.04 ℃
Measuring range :-55 ℃～+ 125 ℃ number change-over times: 1 second
Antistatic: ESD ± 10000V water resistance: IP66
Cable for measuring temperature length: 300 meters
By like this temperature sensor being packaged in the cable for measuring temperature of forming in the cable, can be under the environment of strong jamming, inclement condition steady operation.Transducer can stand the high pressure of ESD10000V.Simultaneously, be convenient to construction construction, can not cause yet come off, phenomenon such as water inlet.
In the power failure supervisory control system, use, with power cable lay with cable trough in, be used for the monitoring power cable operating temperature, operation is more than 2 years, the damage of never breaking, be immersed in water, transducer phenomenon such as come off.
