Description
1、OverviewThis series of products are widely used for measuring DC current, voltage, AC current, voltage, frequency, phase, etcPower and other non electrical analog measurement.2、 Main technical parameters. The accuracy is 1.5 and 2.5;. Service conditions: - 25 ℃ - 40'c, relative humidity ≤ 80% (25 ℃);. Mechanical properties: it can withstand acceleration of 30 m / s, impact frequency of 80-120 times per minute, and 2-hour transportation bumps;. Insulation strength: AC voltage of 50 Hz, 2 kV, duration of 1 minute;. Voltage influence: when the self rating value changes by ± 15%, the error of indication value does not exceed the basic error;
. Working position: vertical direction
This series of instruments are direct analog display electrical measurement indicating instrument, measuring DC current, voltage, AC current, voltage, frequency, power factor, phase sequence, power, synchronous indication and other non electrical measurement. It is widely used in various AC and DC power transmission and distribution systems, power control panels and other electrical equipment in marine, rail transit, chemical explosion-proof, low-voltage complete equipment, construction equipment, generator set, mechanical equipment and other industries. It is a medium and high-grade instrument which is suitable for general requirements of environmental conditions.Standards and certification:The pointer instrument is manufactured according to GB / t7676-1998, the digital display instrument is manufactured according to GB / t22264-2008 standard, and its safety performance is manufactured according to gb4793 and iec61010 standards. The scale mark and pointer design of the dial are in accordance with German din43790 and din43802 standards. The appearance and opening size of the instrument are manufactured according to GB / t1242 and iec61554 standards. All products have passed the national CE certification and obtained ISO; 9001 certification.Plate surface shell aspect:The base is made of flame retardant TBT plastic, Vicat temperature is 130 ℃. The shell is made of flame retardant ABS plastic, and the Vicat temperature is 85 ℃.In terms of the amount of change caused by temperature:The reference temperature was 23 ℃± 2 ℃. Within the temperature range of 13 ℃ ~ 23 ℃ and 23 ℃ ~ 33 ℃, the allowable change of temperature effect is not more than ± 100% of grade index.Installation position and installation method:Unless otherwise specified, instruments are normally installed in a vertical position. Other installation positions such as horizontal installation and inclined installation can be made according to customer requirements. The corresponding accuracy level is only valid for the specified installation position. The instrument is divided into two kinds of indication angles: right angle 90 ° and wide angle 250 °.The influence of vibration and shock resistance is as followsAnti vibration: in accordance with iec60068-2-6 standard; sweep frequency range: 10-55-10hz; displacement amplitude: ± 0.15mm, ± 0.3mm.The results showed that the frequency sweep cycle times: 5 times; sweep rate: 10ct / min; maximum acceleration: 147m / S2 (15g), 490m / S2 (50g).Acceleration effective value: 6.06g; vibration time: 15min. It is resistant to mechanical shock and conforms to iec60068-2-27 standard.Accuracy level:Pointer instrument: AC / DC voltmeter and ammeter are at level 1.5 or 2.5, power meter is at level 2.5, frequency meter is at level 2.5, and power factor meter is at level 2.5.For overload ammeter:The overload times are usually 1 times and 2 times overload times, which can be customized to 1 times, 2 times, 3 times and so on. Its function is to indicate the approximate value of instantaneous overload current, such as the starting current when the motor is started.
