Abstract
The invention relates to an equipment voltage monitoring instrument comprising a wireless voltage measurement sensor and a data recorder. The inside of the wireless voltage measurement sensor includes a three-phase voltage measurement circuit and a micro-power wireless transmission circuit. The data recorder is mainly composed of a micro-power wireless transmission circuit and a GPRS transmission circuit. The equipment voltage monitoring instrument can monitor and measure abnormality of a voltage loop around the clock, professional are noticed immediately once there is an abnormality, the work is changed from passive to active, the on-site construction quality of construction units can be effectively controlled inside, and the efficiency is increased exponentially. After the equipment voltage monitoring instrument is applied, users can carry out check and processing in a targeted manner according to specific problems, and the work efficiency is improved.
Description
Technical field
The invention belongs to electric energy metrical field, especially a kind of equipment voltage monitoring instrument.
Background technology
It is the maintenance work the most frequently that dress table outworker is engaged in that measuring apparatus fault place lacks, and decompression and voltage phase shortage are two kinds of the most common fault types, the important indicator of Ye Shi company inspection monitoring.For three-phase and four-line electric energy meter, along with the successful Application of power information acquisition system, can realize monitoring the voltage condition of electric energy meter; But power information acquisition system is reaction table meter builtin voltage only, cannot compare with step down side virtual voltage situation.Staff is because user's power receiving equipment problem causes often through the report to the police discovery of reaching the spot of acquisition system decompression, and count secondary circuit irrelevant with table, do not affect metering, thus cause staff to come back after a vain attempt.Voltage detector is arranged on step down side, can measure, gathers, processes and store client's three-phase voltage data, and through micropower wireless channel, three-phase voltage data are sent to datalogger to the actual low-pressure side voltage of transformer.Datalogger can GPRS or GSM message mode data retransmission in power information acquisition system main website, outside autonomous system or managerial personnel's mobile phone.Count voltage by real transformer secondary side voltage with table to compare, table meter secondary circuit failure can be determined whether.
Summary of the invention
The object of the invention is to overcome prior art deficiency, a kind of cost-saving equipment voltage monitoring instrument is provided.
The technical solution used in the present invention is:
A kind of equipment voltage monitoring instrument, comprise wireless voltage measurement sensor and datalogger, wireless voltage measurement sensor inside comprises three-phase voltage metering circuit and micropower wireless transmission circuit two parts, and datalogger is primarily of micropower wireless transmission circuit and GPRS transmission circuit two parts composition.
And described wireless voltage measurement sensor is square ABS engineering plastics shell, and datalogger is aluminium section bar instrument square shell.
And wireless voltage measurement sensor to record after magnitude of voltage by micropower Wireless transceiver to datalogger, registering instrument with GPRS or GSM message mode data retransmission in power information acquisition system main website, outside autonomous system or managerial personnel's mobile phone.
Advantage of the present invention and good effect are:
The present invention can the unusual condition in round-the-clock monitoring metered voltage loop, has extremely to notify that professional processes immediately, and work is changed from passive to active, and can carry out effectively control in inside unit in charge of construction's site operation quality, efficiency significantly improves.After application, can carry out just lacking property inspection, place for particular problem user, increase work efficiency.
The work on hand mode of power supply enterprise place shortage of staff person can be changed after application the present invention, scene need not be gone to get final product long-range understanding actual conditions, avoid the sky race phenomenon because user's self reason causes, for power supply enterprise saves a large amount of human and material resources.Every platform equipment can save more than 30 ten thousand yuan for enterprise every year.
