Abstract
The utility model provides an automatic regulating and controlling load tank and is connected into by Ra to Rn resistances with different resistance values. A relay ordinary opening contacting point is connected among the resistances to achieve the 2 logic combination resistance value. Because multiple resistances with different resistance values can be logically combined, the discretional resistance value can be generated. The extension is convenient, and the regulating precision is enhanced. In the detecting process, the electrical discharge hour rate of an accumulator battery can be selected, and a main controlling device automatically traces, controls and regulates the constant current electricity discharging process. The working time is shortened, and the hard manual operation is relieved. In the working process, the automatic regulating and controlling load tank is not red and hot. The automatic regulating and controlling load tank also has small size, light weight and long service life.
Description
The utility model relates to a kind of load box, especially a kind of auto-control load box that detects usefulness as power supply capacitys such as battery pack.
In commercial production, especially in the communication technology, need timing that load (lotus) ability, the capacity of power supplys such as battery pack, rectifier, genset are detected, to guarantee the normal operation of equipment.Except that using detector, also must mix the detection load during detection, so that accurately measure.But not only volume is big for regulation and control load box of the prior art, Heavy Weight, and also when work is easily rubescent, hot, can only lean on artificial regulatory, and the resistance value adjustable extent of generation is little, and degree of regulation is poor, does not satisfy the needs of high speed development.
The purpose of this utility model is to provide a kind of volume little, in light weight, and not rubescent during work, not hot, Standard resistance range is big, the auto-control load box that degree of regulation is high.
The utility model is such: it is controlled by primary controller, and switches the logical combination of realizing different resistances by relay contact, plants resistance value arbitrarily thereby produce.
Concrete scheme of the present utility model is that it is by Ra ... the resistance of Rn different resistances is formed by connecting, and is connected with relay normally open contact between the resistance, so that by the primary controller pilot relay, realizes the conversion of contact switch, thereby constitutes 2 logical combination resistance values.Wherein the resistance of different resistances adopts series connection, and perhaps in parallel, perhaps the connected mode of series-parallel connection connects, the input end of resistance is connected with protective resistance, and current transformer, so that after sampling current and reference current are compared, calculate and control by primary controller; Resistance R a ... Rn adopts the resistance alloys of spring-like or spiral fashion or other shape, is convenient to heat radiation, and making it pass through the 600A electric current can be not rubescent, hot yet.
The utility model compared with prior art has following advantage and extremely long-pending effect: owing to the resistance of a plurality of different resistances can be carried out logical combination, make it to produce any kind of resistance value, expansion is convenient, improves degree of regulation.During detection, can select the discharge hour rate of battery pack, and, shorten the working time, remove cumbersome manually-operated from by automatic tracking Control of primary controller and adjusting constant-current discharge.During work, this load box is not rubescent, not hot, and volume is little, and is in light weight, long service life.
