Description
Technical field
The present invention relates to a kind of porcelain strut insulator Machinery State Monitoring System.
Background technology
Porcelain strut insulator is one of key equipment of substation operation, plays the purposes of support protection and electric insulation.
Porcelain insulator belongs to the electrotechnical porcelain product being sintered at high temperature into itself, and its improper mixed with raw material being formulated uneven may cause
Porcelain piece internal flaw in sintering procedure so that its mechanical strength reduces.Meanwhile during long-term use, porcelain strut insulator
Need the influence for bearing larger mechanical load and weather conditions change so that porcelain insulator generation tiny flaw, and then by
Destroy.Once breakage occurs in support insulator, the stable operation of its power equipment carried will be threatened greatly.With
Power system and the integration of power grid construction and complication, once some equipment is damaged, influence will be all brought to power system, because
This, monitoring stable operation of the mechanical condition of porcelain strut insulator to power system has great meaning.
Such as a kind of porcelain strut insulator Machinery State Monitoring System is disclosed in Chinese patent CN201620827026.8,
The system is made up of sensor, signal processing module, trunk module, control module, power exciter, control cabinet, by by power
Exciter is placed in support insulator flange in the bottom and produces vibration, then vibration signal is acquired by sensor, and passes through biography
Defeated system transmission postpones platform PC ends, is analyzed using daemon software, the machinery of porcelain strut insulator is judged according to vibration signal
State；A kind of porcelain strut insulator Machinery State Monitoring System, the system are disclosed in Chinese patent CN201410110351.8
System is made up of wireless senser, signal processing module, power exciter, trunk module, center signal processing module, is excited by power
Device produces vibration, and measures vibration signal by sensor, and is wirelessly transferred, and trunk module receives wireless signal and transmitted
To center signal processing system, by the machine performance that research and application porcelain strut insulator is carried out to vibration signal.These methods
Vibration is produced by vibrator porcelain strut insulator, and judges the machine of porcelain strut insulator by analyzing vibration signal
Tool state, but the vibration of vibrator in itself may cause the machine performance of porcelain strut insulator further to dislike to a certain extent
Change, meanwhile, circuit structure is complex, equipment power supply inconvenience.
The content of the invention
, can be to support insulator it is an object of the invention to provide a kind of porcelain strut insulator Machinery State Monitoring System
Machine performance is monitored on-line, and be particularly suitable for use in transformer station's support insulator equipment, has effectively ensured the peace of power equipment
Row for the national games.
A kind of porcelain strut insulator Machinery State Monitoring System, it is particular in that：Including installed in porcelain post insulator
Radio frequency resistance strain gauge transducer on sub- column, the radio frequency resistance strain gauge transducer wirelessly with wireless senser
Signal receiver is connected, and the wireless sensor signal receiver is connected by data collecting card with background terminal.
Wherein wireless sensor signal receiver is installed on the ground by receiver support frame.
Wherein radio frequency resistance strain gauge transducer is also connected with solar power supply apparatus.
, can be to porcelain strut insulator the invention provides a kind of Machinery State Monitoring System for porcelain strut insulator
Monitored on-line, and analyze its machine performance, effectively ensured the safe operation of power equipment.
Beneficial effects of the present invention also reside in：1st, used by present system wireless senser using solar powered,
Without power-supply device, therefore circuit is simple, while plays a part of energy-conserving and environment-protective, and use condition greatly simplifies, service life
It is corresponding to extend；2nd, present system is by measuring machinery of the stress-strain situation to porcelain strut insulator of porcelain strut insulator
State is assessed, it is not necessary to using excitational equipment, is avoided influenceing the machine performance of porcelain insulator, is reduced equipment sheet
Destruction of the body to porcelain strut insulator.3rd, present system is changed come to porcelain using the stress-strain of porcelain strut insulator
The machine performance of support insulator is detected, and signal analysis process is simple, and accuracy is higher, can be preferably exhausted to porcelain pillar
The machine performance of edge is monitored.
Brief description of the drawings
Accompanying drawing 1 is the structural representation of the present invention.
Embodiment
Shown in reference picture 1, transformer porcelain strut insulator Machinery State Monitoring System of the present invention, including radio frequency resistance
Strain gauge transducer 2, wireless sensor signal receiver 3, data collecting card 4, receiver holder, background terminal 6.It is described wireless
Resistance strain type sensor 2 straingauge, sender unit composition, is mainly used in measuring porcelain branch by solar panel
The stress-strain situation of post insulator；Wireless sensor signal receiver 3 is used to receive wireless sensor signal, and signal is entered
Row amplification, and transmitted by wired mode to data collecting card 4；Data collecting card 4 is mainly used in receiving after treatment
Stress-strain signal, and transmit signals to background terminal 6；Receiver support frame 5 be used for signal receiver is supported with
Protection；The computer of background terminal 6 is handled signal, draws load-deformation curve, and tested porcelain strut insulator is carried out
Monitoring, porcelain strut insulator is positioned when porcelain strut insulator occurs abnormal, remind operation maintenance personnel to be detected and tieed up
Shield.
Other radio frequency resistance strain gauge transducer 2 is surveyed at a certain time interval by the way of solar powered
Amount.
The present invention application method and operation principle be：
During work, radio frequency resistance strain gauge transducer 2 is affixed on the porcelain knob at the middle full skirt interval of column 1 of porcelain strut insulator
On, according to the Electric Field Distribution situation of support insulator, middle part electric-field intensity is most weak, is advantageous to extend the service life of sensor,
Sensor is monitored in real time to the ess-strain situation of porcelain knob, while Monitoring Data is once sent per half an hour, is believed
Stress-strain situation is not only included in number, also comprising the station location marker for surveying porcelain insulator.
Wireless sensor signal receiver 3 receives sensor and signaled, after amplification by way of wire transmission
Data collecting card 4 is sent to, and background terminal 6 is sent to by data collecting card 4.Background terminal 6 monitors porcelain strut insulator
Ess-strain situation simultaneously draws curve, and under normal circumstances, the ess-strain situation of porcelain strut insulator should be stablized relatively, work as letter
Alarm is sent when number being widely varied, and points out monitored porcelain insulator positional information, reminds operation maintenance personnel to the porcelain
Support insulator is detected and safeguarded.
It should be noted that the software of background terminal 6 comprising above-mentioned operation principle belongs to existing conventional techniques means.
