Description
Technical field
The present invention relates to a kind of transmission tower high-tension cable intelligent monitoring device.
Background technology
The acquisition method of present feeder cable line terminal ground voltage and electric current, main manual work is stepped on tower and is utilized pincerlike meter to measure.Because urbanization and samll cities and towns' construction are quickened; Terminals, ground connection case increase sharply on the shaft tower of the use of cable line and mixed frame; Acquisition method monitoring according to cable operating standard voltage and current will receive shaft tower and cable bare wire to mix the influence of electric parameters such as frame on the one hand, receives the influence of specialty point and operation on the other hand again; In reality because the operation; Particularly circuit close on, with other circuit of tower and different specialty; During a plurality of working groups operations; Acquisition method every the circuit in monitoring collection point that needs feeder cable line terminal secondary ground voltage and electric current lacks safe information technology control etc. owing to do not have information source collection and control.
Especially the current remote circuit of high-voltage cable does not have the information source of a feeder cable line terminal secondary ground voltage and electric current, particularly increases day by day and mixes frame cable line terminals, and as the annex of cable line etc., realizes that intelligent control monitors.
It is many to mix frame cable line branch earth point, relates to how tame needs of work such as power supply unit, Subscriber Unit transmission tower cable terminal secondary grounding monitor has been adopted the collecting work of mutual voltage and electric current, the more comprehensive monitor message of needs.
Prison voltage and current monitoring technology requires on the power transmission and distribution cable line cable terminal secondary extension bar tower according to waiting, the requirement of whole service monitoring standard; From safety, the reliable and accurate coefficient balance of data acquisition, key personnel's rod-rising tower measuring method of promoting now is to choose first method.Normally make an inspection tour the monitoring periods arrangement according to operating standard.Run unit is according to cable and fixed cable terminal group number and the shaft tower contrast of the charged work ticket row of circuit, and it is different that the operating personnel relates to specialty; The work permit order is dual; The staff fulfils the work permit formality, handles work ticket, explains safety practice and dangerous point; The operating personnel arrives work ticket institute column position, and the operating personnel needs the safety custody measure.Begin to step on bar and carry out work, belong to work high above the ground from technical the saying of operating environment; Since circuit with equipment and user's branch line more, add on shaft tower collection voltage and current etc., operating condition belongs to high-risk status; Operation and monitoring two people are on bar and work on the spot.The personnel that work on the whole bar need work high above the ground; And, need to carry out on the bar 4 two identical mutual voltages and electric current time monitoring collection and repeat work.
Existing employed survey instrument mainly comprises pincerlike meter, record sheet etc., and electric pressure is high more, and the induced voltage of survey crew and live wire is also outstanding more, and is also high more to person induction.And shaft tower is high more, and the ground connection case of cable just requires high more, does not allow during personnel's operation to measure; Sometimes meet the hardships rain and dew, shaft tower body portion or adhere to frosting etc., the needed Measuring Time of operation is just longer.Measure on the operation process king-rod with bar under personnel labor intensity high, cause muscular fatigue to cause danger easily.Cable professional particularly, shaft tower on operation, accidents such as falling object from high altitude very easily take place; Because the monitoring of transmission tower cable terminal secondary has adopted the acquisition method time of mutual voltage and electric current long, active section can not get protection, and the field intensity of other induction instrument aratus is higher can't to mask, and influences surveying work progress and accuracy.
Summary of the invention
According to above deficiency of the prior art, the technical matters that the present invention will solve is: provide a kind of and can overcome above-mentioned defective, reduce task difficulty, the transmission tower high-tension cable intelligent monitoring device of raising labour efficiency.
The technical solution adopted for the present invention to solve the technical problems is: a kind of transmission tower high-tension cable intelligent monitoring device; Comprise iron tower and be installed in the secondary line on the iron tower; It is characterized in that: also comprise voltage current transformer, connecting line and data acquisition emitter; Voltage current transformer one end is connected with secondary line, and an end is connected with the data acquisition emitter through connecting line, and the data acquisition emitter is arranged on the iron tower.
Described data acquisition emitter comprises data acquisition unit, single-chip microcomputer and wireless launcher; Voltage current transformer connects data acquisition unit through data line; Data acquisition unit connects the input end of single-chip microcomputer, and the output terminal of single-chip microcomputer connects wireless launcher.
Described wireless launcher is the gsm wireless emitter.
Voltage and current on the voltage current transformer induction secondary line; Induction current is sent to data acquisition unit through connecting line; Data acquisition unit converts induction current into digital signal and sends single-chip microcomputer to; Single-chip microcomputer sends the data to wireless launcher after through analytical calculation, and wireless launcher sends signal to supporting with it receiving terminal, accomplishes monitoring.
The beneficial effect that the present invention had is:
Reduced task difficulty.Collection needs 2 people on the former operation bar, needs 1 people to get final product through computer operation on the backstage now, personnel's ability multiple spot collection analysis; Accomplish the optimization collection, realize laborsaving, save time, reduce to threaten because of the operation induced voltage; Guaranteed that data acquisition is reliable, accomplished safe and reliable operation.
Compare with traditional measurement, operational measure of the present invention does not have difficulty, has reduced staff's process management and labour intensity, has guaranteed safety in production indirectly.Survey crew reduces to 1 people's consistency operation by 2～3 people on the bar, and measurement can be in real time and 24 hour records; Subtract few 100% minute of time, improved efficiency.
