Description
Technical field
The utility model relates to the system of the overheated real-time monitoring of high-voltage cable joint.
Background technology
High-tension cable uses frequently in the industrial enterprise in modern times, in industrial and agricultural production, brought into play huge effect, but the thing followed is the occurrence probability cumulative year after year of cable fault.In case cable generation security incident, the lighter has a power failure, stop production to overhaul, and weight person will cause serious fire failure, and consequence is very serious, and repair is also extremely difficult, and its economic loss that causes can not be underestimated.In recent years, some have taken place because of overheated on fire, the explosive incident that takes place, therefore on high-voltage cable; Carry out the cable security Study on Monitoring Technology; To early detection cable fault hidden danger, avoid the generation of fire and explosion accident, have very significant meaning.To because of the overheated accident that takes place, at present oneself is through there being a lot of temp measuring methods to apply in the cable security supervisory system.Temperature-sensing element commonly used mainly contains infrared sensor, thermopair, thermistor, semiconductor PN knot, temperature control thyristor and integrated circuit type temperature sensor etc.The infrared sensor biggest advantage is a non-cpntact measurement, thereby has good security, and its shortcoming is complex structure, poor anti jamming capability, and is high to environmental requirement; The thermopair transmission signals need be used special-purpose compensating line, and transmission range is unsuitable oversize, is not suitable for the cable temperature monitoring; Thermistor is generally RTD, generally needs to adopt the three-wire type transmission, the output of balanced bridge formula, and transmission range is also unsuitable oversize, and anti-jamming capacity is relatively poor; Semiconductor PN junction type and temperature control thyristor-type sensor all are not suitable for the monitoring of cable temperature yet.Therefore, be applied in the measurement of cable outside wall temperature the characteristics that disguise is high because the cable superheating phenomenon has, temperature rise in early age is slow, be difficult to detect although have multiple temp measuring method at present.Under normal conditions, be superheated to accident from cable end and take place, whole process slower development, overlong time, the temperature rise in early age phenomenon is not obvious, and current measuring methods is difficult to monitor effectively.
Summary of the invention
The purpose of the utility model provides the overheated real-time monitoring system of a kind of high-voltage cable joint, and the temperature that monitors cable splice that this monitoring system can be real-time makes the heat energy of crossing of cable splice in time come to light, and guarantees the safety of electrical production.
For achieving the above object; Communicate by letter concentrator, the concentrator of communicating by letter with RFID of the overheated real-time monitoring system of a kind of high-voltage cable joint, the RFID that comprise the sensing communicator of combining closely with cable splice, transmits information through the RFID communication carries out the server and the monitor workstation display terminal of wired or wireless communication.
As specializing, the sensing communicator comprises the temperature sensor of combining closely with cable splice and accepts the temperature sensor temperature signal and temperature signal is transferred to the RFID RFID transport module in the concentrator of communicating by letter.
The course of work of the monitoring system of the utility model is: the sensing communicator is the temperature of exploration cable joint at any time; And the temperature signal that detects is delivered in the RFID communication concentrator through the RFID communication; The temperature signal that RFID communication concentrator is come in to transmission is handled and through wireless or wired mode processing signals is transferred to server; And the temperature variation of watching cable splice through the monitor workstation display terminal; To make processing scheme timely, prevent the generation of security incident.
Have the advantages that to the high-tension cable superheating phenomenon disguise is high, temperature rise in early age is slow, be difficult to detect; Compared with prior art; This monitoring system can monitor the temperature of cable splice at any time, makes the heat energy of crossing of cable splice in time come to light, and guarantees the safety of electrical production.

Fig. 1 is the system architecture synoptic diagram of the overheated real-time monitoring system of high-voltage cable joint of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further elaborated.
Communicate by letter concentrator 2, the concentrator of communicating by letter with RFID of the overheated real-time monitoring system of high-voltage cable joint as shown in Figure 1, the RFID that comprise the sensing communicator 1 of combining closely with cable splice 10, transmits information through the RFID communication carries out the server 3 and the monitor workstation display terminal 4 of wired or wireless communication.Described sensing communicator 1 comprises the temperature sensor 11 of combining closely with cable splice and accepts the temperature sensor temperature signal and temperature signal is transferred to the RFID RFID transport module 12 in the concentrator of communicating by letter.Above-mentioned described RFID communication concentrator 2 refers to communicate through optical fiber or ethernet coaxial cable with wire communication between the server 3, and the described RFID concentrator 2 of communicating by letter is meant that with radio communication between the server 3 GPRS communicates by letter.
The course of work of the monitoring system of the utility model is: temperature sensor 11 is surveyed the temperature of each cable splice at any time; RFID transport module 12 is accepted will be sent to the temperature signal of cable splice in the RFID communication concentrator 2 from the temperature signal of temperature sensor 11 and through the RFID communication; RFID communication concentrator is classified, is gathered and handle the temperature signal of each cable splice and through wireless or wired mode processing signals is transferred to server 3; And the temperature variation of watching cable splice through monitor workstation display terminal 4; To make processing scheme timely, prevent the generation of security incident.
