Description
Technical field
The present invention relates to a kind of ring main unit passive and wireless temperature online monitoring system.
Background technology
The original definition of ring main unit is the outlet switch cabinet set by each distribution branch road on looped network.That is, annular
Main line is to be connected to collectively constitute by the bus of every outgoing line cabinet, and every outgoing line cabinet is just ring main unit.Actually individually take out
One ring main unit does not see the implication of " looped network ".The rated current of these ring main units is all little, thus the high-voltage switch gear of ring main unit
Typically baroque breaker is not used and the high voltage load switch simple in construction with high-tension fuse is taken.Ring main unit is used
On-load switch operates normal current, and two cut off short circuit current flow with fuse, and both combines substitution breaker.This switch cubicle is complete
In the distribution system that non-ring network structure can be used entirely, then widely using with this switch cubicle, ring main unit has been jumped out
The category of looped network distribution and refer to the high-tension switch cabinet using on-load switch as main switch.
All-insulated ring network cabinet relies on its superior environmental suitability, can be under the adverse circumstances such as plateau, humidity, high wind sand
Normal operation, with very big use advantage.The equipment is not in the situations such as insulation, arc extinction performance decline or short circuit, is made
Obtain overall structure to be in the state encapsulated entirely, without design drive disk assembly outside it, so as to ensure for example strong in adverse circumstances
Safety in utilization under dust storm etc..Used if in high and cold humid area, it has outstanding decay resistance, is not in
The situation such as get rusty, the performance and quality of product are all without producing influence.
In actual use, cable accessory joint fault rate is high for ring main unit.Typical fault causes for loose contact
Electric shock temperature is raised, if handling not in time, cable connector may be caused to burn, and even results in ring main unit blast.Therefore need
Strengthen strengthening on-line temperature monitoring to ring main unit cable accessory joint, find failure, handle early, it is to avoid because heating causes
Accident further expands.
The content of the invention
For problems of the prior art, it is an object of the present invention to provide a kind of passive and wireless temperature applied to ring main unit
Spend on-line monitoring system.The system is based on surface acoustic wave (SAW using a kind of：Surface Acoustic Wave) technology it is new
Type passive wireless temperature sensor, the sensor utilizes the physical characteristic of crystal installed therein, without operating circuit, is not required to
Power, and the communication with signal transmitting and receiving antenna is realized using wireless radiofrequency mode, really realize hi-lo circuit separation fortune
OK.The system has temperature sensor simple installation quick, and high-tension apparatus power off time is short；After installation, without having a power failure more
Change battery；Power taking need not be sensed, trouble point is few, the features such as without interruption maintenance.
The present invention is achieved through the following technical solutions：
Ring main unit passive and wireless temperature online monitoring system includes multiple novel passive wireless temperatures based on surface acoustic wave
Sensor, multiple radiofrequency signal dual-mode antennas, an analyzer.Novel passive radio temperature sensor can be directly installed on three
On phase cable connector.Radiofrequency signal dual-mode antenna is installed in cable vault.One analyzer is installed on any of one group of ring main unit
In one interval, it can also be arranged in DTU units.
Signal processing module control signal transmitter module in analyzer is by radiofrequency signal dual-mode antenna to novel passive
Radio temperature sensor sends its feature rf frequency signal, and the sensor receives radio frequency by self-contained helical antenna to be believed
After number, the surface acoustic wave of plane of crystal in sensor, the spread speed of this surface acoustic wave and the temperature of crystal are translated into
There is certain characteristic relation.By setting reflecting grating in sensor crystal, make to produce resonance in sensor crystal, resonance is produced
Radiofrequency signal by novel passive radio temperature sensor helical antenna launch.When returning radiofrequency signal generation, pass through
The signal receiving module of analyzer signal processing module control is in work.The passback radiofrequency signal of reception is analyzed device analysis
The crystal temperature effect on novel passive radio temperature sensor is obtained afterwards.
Analyzer obtains all temperature of cable junction data and realized by original DTU module in ring main unit in data
Pass.
Beneficial effect：Novel passive wireless temperature in the ring main unit passive and wireless temperature online monitoring system of the present invention is passed
Sensor uses contact temperature-measuring, therefore crystal temperature effect therein is identical with contact point temperature.The novel passive wireless temperature is sensed
Device, without low voltage operating circuit, without power supply, realizes height in ring main unit using the physical characteristic of the crystal wherein included
Pressure side is kept completely separate, and using safety, and reduces line service.
Novel passive radio temperature sensor exempts to apply for frequency range with radiofrequency signal dual-mode antenna using 433MHz, and entirely penetrates
Frequency communication is carried out in metal-enclosed type ring main unit, will not produce influence by remaining communication equipment to surrounding.
One analyzer can connect six antennas, and each antenna can control three temperature sensors.Make in the system
Novel passive radio temperature sensor utilize material physical characteristic, it is not necessary to power supply, and with radiofrequency signal dual-mode antenna
Communicated using wireless mode, really realize the passive and wireless thermometric of ring main unit middle cable connector.
