Description
The utility model relates to a kind of mechanical type watt-hour meter with digital signal output, belongs to the electromechanical assembly of measuring electric power.
In year surplus the mechanical type watt-hour meter invention existing 60, because it is simple in structure, long-time running is reliable, so far still be widely used in industry and civilian electrical measurement, but under electricity charge count by time sharing system from now on, this single charging electric meter can not be realized the time-sharing measurement to electric weight.
Introduce existing multi-rate meter in " Electrical Measurement Technology " that " electric instrument product sample " that the 1980.7. of China Machine Press publishes and the 1991.3. of China Measuring Press publish, by principle, had two kinds:
A kind of is the mechanical type watt-hour meter.Its adopts and to punch on watt-hour meter dial, adds a light beam then, and the light pulse that produces by to dial rotation the time is counted, subsequently by timer control to the electric weight time-sharing measurement.Therefore its outside charging circuit must be in the energising duty constantly, has so just brought shortcomings such as power consumption is big, reliability is low, serviceable life is short.
Another kind is totally digitilized watt-hour meter.It adopts various circuit that voltage, the current signal of transmission line of electricity are carried out digitized processing.This class digitizing watt-hour meter, general precision is than higher, but complex circuit, cost is higher, and circuit equally must be constantly in running order, plants the shortcoming of ammeter before therefore can't overcoming.Simultaneously, the production of this class ammeter can't be finished on prior mechanical watt-hour meter production line basis, needs very big investment, and if replace existing machinery formula watt-hour meter comprehensively, will cause huge waste.
The purpose of this utility model be to overcome the deficiencies in the prior art part and provide a kind of low in energy consumption, the life-span long, simple in structure, reliable and can realize the mechanical type watt-hour meter of multiple rate accounting.
The purpose of this utility model can reach by following measure:
In general mechanical type watt-hour meter, counting is counted demonstration according to certain rules by the axle drive character wheel of rotating disk.The measure that the utility model is taked is each numeral on the character wheel is encoded, and makes it to handle with certain device identification with digital circuit.Coded system has a variety of, and its common ground is with the least possible each numeral of binary coding representation 0-9.For example, Fig. 1 represents a kind of character wheel with 8421 code encoding methods.The logic detection value of dash area is a logical one among Fig. 1, and outermost shade weights are 1, and taking second place is 2, and taking second place is 4 again, and inner ring is 8, and then coding of each number meets 8421 yards.Photovoltaic is adopted in digitally coded detection, and promptly dash area is transparent to detecting light among Fig. 1, and non-shaded portion is opaque, otherwise or.
The utility model is made up of framework, character wheel, detector bar, rotating shaft, runner, detector bar fixed bar, rounding wheel and carry wheel shaft.Character wheel is by encoding by certain binary coding mode to represent that natural dash area and non-shaded portion constitute; Rotating shaft, detector bar fixed bar and carry wheel shaft are installed on the framework; Four rounding wheels are installed on the carry wheel shaft; Four character wheels and runner are installed in the rotating shaft, rotating shaft drives the runner rotation, first rounding wheel engagement in runner and the rounding wheel, install four rounding wheels and four character wheel spaces, rule Data transmission by " full decade ", first character wheel (i.e. a position character wheel) that is the units of first rounding wheel and expression metering meshes individual character wheel back, position and second rounding wheel engagement; Individual position character wheel turns around full ten, make second character wheel (ten character wheels) change one by second rounding wheel, treat that ten character wheels turn around full ten, make the 3rd character wheel (hundred character wheels) change one by the 3rd rounding wheel again ... transmit carry so step by step, four character wheels represent respectively stoichiometric number, ten, hundred, kilobit; Detector bar is installed in the both sides of each character wheel symmetrically, every detector bar is made up of four equidistant optical fiber of placing, the detector bar of one side of each character wheel is luminous group, be used to introduce light source, detector bar at the opposite side of character wheel symmetry is the reception group, be used for receiving optical signals, that is to say, the coding of each numeral is promptly had or not by four optical fiber of reception group and receives light signal and read among Fig. 1; Luminous group links to each other with light source, and the reception group links to each other with photoelectric switching circuit, and light source and photoelectric switching circuit all are connected on the external interface plug-in unit, and external circuit can be from the plug-in unit reading of data.During work, external circuit by timing circuit be controlled at the branch time point to the shown data of each electric supply meter gather, calculate, storage etc., work finishes, external circuit enters idle state, system is in low power consumpting state, only keeps the data of storer, produces up to next look-at-me; When Alternating Current Power Supply stops, producing look-at-me by power detection signal, field data is preserved; Power unit can provide and preserve the required support of power supply in short-term of field data when having a power failure.
The utlity model has following advantage:
1) owing to be on prior mechanical watt-hour meter architecture basics, to improve,, can realize the function of multi-rate meter again owing to adopt numerical coding output so it has inherited original simple in structure, the reliable advantage of mechanical type watt-hour meter.
2) implementation method of the present utility model is simple, as long as prior mechanical watt-hour meter character wheel parts are replaced, just can realize.
3) good in economic efficiency, the current mechanical type watt-hour meter that is using need not be scrapped, and only needs to replace former character wheel with the character wheel that the utility model proposed, and promptly can be used for time-shared charge; Prior mechanical watt-hour meter production line also need not be scrapped, and can continue to continue to employ.
4) the utility model cost is low, invests little.
5) compare with existing multi-rate meter, external circuit of the present utility model need not be constantly in running order, under same environment, can reduce the power consumption of metering circuit on the one hand, the more important thing is the reliability that can improve system's long-time running, prolong system serviceable life.
6) in the mechanical type watt-hour meter, character wheel is parts independently, therefore replacing character wheel need not change the basic structure of mechanical type watt-hour meter, so this method that the utility model adopts both can be used for single-phase watt-hour meter, also can be used for three-phase three-wire system watt-hour meter and three-phase four-wire system watt-hour meter.
