Abstract
A real-time monitoring method of a power distribution network line contact temperature and a monitoring system are disclosed. By using the method and the system, problems that a power supply department can not carry out monitoring in real time and it is difficult to discover that the contact temperature is increased can be solved. The method is characterized in that: a critical temperature thermistor is arranged on a position of the power distribution network line contact so as to carry out contact temperature overheating acquisition; when the contact temperature is greater than a set critical value, the critical temperature thermistor and a wireless transmitter form a loop so as to emit a wireless alarm signal; through a wireless communication base station, the alarm signal is acquired and then is transmitted to a wireless communication center; the wireless communication center sends the fault point alarm signal to a wireless receiver in a monitoring center of a power supply department; the signal received by the wireless receiver is beamingly displayed on a light-emitting panel of a line simulation graph; the wireless communication center simultaneously sends a short message to a mobile phone of monitoring personnel so as to remind the personnel. By using the method and the system of the invention, power consumption is extremely low and energy saving can be achieved. A transmission distance is long and an anti-interference function can be achieved. A contact overheating burning loss accident can be controllable and can be controlled again.
Description
Technical field
The present invention relates to a kind of power distribution network line contacts temperature method for real-time monitoring and supervisory system that is applied in electric system.
Background technology
In recent years; Though make the operation level of power supply network that development at full speed arranged through means such as continuous electric network reconstruction, technical renovation; That reason causes is overheated and over-heated fault happens occasionally but annual each contact of power distribution network circuit is owing to disaster, load growth be too fast etc.; Directly cause user's phase-deficient operation or compelled the power failure, cause serious economy loss and social influence for power supply enterprise, user.Because power supply department is generally one month once to the tour cycle of circuit, equipment; Existence conditions is not accomplished real-time monitoring; The insulating level of line facility is increasingly high now in addition, and a lot of line contacts all are to be insulated outer cover to wrap up, and the electromagnetic inductor of present common employing is difficult to find when contact temperature slightly raises; The electromagnetic inductor operating temperature range is little in addition, and sensitivity is low when outdoor environment temperature changes greatly.
Summary of the invention
The present invention to solve existing power supply department long to tour cycle of circuit, equipment, can not monitor in real time and the contact temperature back that raises is difficult to the problem found, a kind of power distribution network line contacts temperature method for real-time monitoring and supervisory system that is applied in electric system is provided.
The present invention is achieved through following technical proposals:
A kind of power distribution network line contacts temperature method for real-time monitoring; Its special character is: lay critical temperature thermistor at power distribution network line contacts place and carry out the overheated collection of contact temperature; When contact temperature during greater than the critical value set the critical temperature thermistor conducting constitute the loop with the wireless launcher of laying on the line near the contact place; Each wireless launcher is set a fixed frequency, and different wireless launchers has different frequencies with contacts different on the corresponding line; Wireless launcher sends wireless alarm signal; Through transferring to the wireless telecommunications center after the wireless communication base station reception; The trouble spot alerting signal is given the wireless receiver that is positioned at power supply department Surveillance center by the wireless telecommunications center; Wireless receiver receives after the alerting signal being positioned on the circuit simulation drawing luminescent panel of power supply department Surveillance center corresponding trouble spot and locates luminous demonstration, shows the trouble spot intuitively; The monitoring personnel's of power supply department Surveillance center sending short message by mobile phone is given at the wireless telecommunications center simultaneously, reminds position, monitoring personnel trouble spot through note.
Above-mentioned wireless communication base station is GPRS or CDMA communication base station.
Above-mentioned wireless launcher is the wireless launcher of electromagnetic induction power supply.
A kind of power distribution network line contacts temperature real-time monitoring system; Its special character is: comprise the critical temperature thermistor that is laid in power distribution network line contacts place, be connected with critical temperature thermistor and lay on the circuit wireless launcher near the contact place; Be used for receiving the wireless communication base station of the wireless alarm signal that wireless launcher sends; Receive the wireless telecommunications center of the next alerting signal of wireless communication base station transmission; Receive the mobile phone that alerting signal of sending at the wireless telecommunications center and the wireless receiver that is positioned at power supply department Surveillance center and monitor staff are equipped with, the circuit simulation drawing luminescent panel that links to each other with wireless receiver.
Above-mentioned wireless communication base station is GPRS or CDMA communication base station.
Above-mentioned wireless launcher is the wireless launcher of electromagnetic induction power supply.
The present invention adopts only just conducting of thermistor when contact is higher than the critical value of setting of critical temperature thermistor, makes the wireless launcher work by the electromagnetic induction power supply, and highly sensitive, power consumption is extremely low, and is energy-conservation.Utilize wireless network communication technique to realize the transmission of fault place contact temperature alarm; Having solved the signal that adopts single transmitting set and wireless receiver receives buildingss such as building to influence the limited problem of transmission range, long transmission distance, strong interference immunity; Do not receive the influence of pile machine such as building on every side; Real-time monitoring can be accomplished,, trouble spot and in time handling can be in time found in conjunction with the tour of power supply department to circuit, equipment; Realization is to causing the controlled of the overheated burning damage accident of contact and control again because of reasons such as disaster, load growth are too fast; Thereby reduce the incidence of contact burning damage accident greatly, prevent user's phase-deficient operation or compelled the power failure, avoid therefore causing economic loss and social influence to power supply enterprise, user.Through establish circuit simulation drawing luminescent panel in power supply department Surveillance center, can show the trouble spot intuitively and accurately; , realize monitoring through the mode that receives SMS, thereby realize comprehensive monitoring during the monitoring personnel each contact not in Surveillance center.
