武汉世纪华胜科技有限公司FS系列放电球隙测压器（FS Series Discharging Sphere Gap Measuring Voltage Instrument） 产品标准： GB/T 311.6-2005 试验标准： DL/T 596-2005 产品概要： FS系列放电球隙测压器，高压试验室必备试验设备之一！ Brief Introduction In the high voltage test, in order to prevent overvoltage and resonance overvoltage from damaging tested equipments，we need to use discharging sphere gap to monitor the voltage，besides using the over-voltage protection. FS series discharging sphere gap measuring voltage instruments have the merits of beautiful appearance，simple wiring and reliable operation.They are one of necessary test equipments in high voltage laboratory. The products comply with the standard GB/T 311.6-2005 high voltage measurement standard air gap. Product Structure FS series discharging sphere gap measuring voltage instrument consists of movable base，insulating pipe，copper ball，regulating shaft (ruler)，trimming wheel，water resistance and so on. Product Operation In the test，the ball gap device and the tested instrument should be parallel，and adjust the ball gap to 60% test voltage. Determine the test voltage value (average value of 34 tests) of the ball gap while it is discharging，then according to the same method，determine the meter reading when it is at 70% and 80% test voltage.Then draw a curve of the three values (mostly it is a straight line), and then extend the curve (mostly calculate in direct ratio) to the position that is 1015% higher than required test voltage as discharging protection voltage to prevent accidents if overvoltage occurs in the process of withstand test.Technical Parameters One-ball-grounding sphere ball applies to AC voltage, negative lightning impulse voltage and long wave tail shock and two-polarity DC voltage kV (peak value).gap distance(cm)balldiameter (cm)56.251012.515250.208.00.259.60.3011.20.4014.314.20.5017.417.216.816.816.80.6020.420.219.919.919.90.7023.423.723.023.023.00.8026.326.226.026.026.00.9029.229.128.928.928.91.032.031.931.731.731.731.71.237.637.537.437.437.437.41.442.942.942.942.942.942.91.545.545.545.545.545.545.51.648.148.148.148.148.148.11.853.053.553.553.553.553.52.057.556.559.059.059.059.02.261.563.064.564.564.564.52.465.567.569.570.070.070.02.6(69.0)72.074.575.075.575.52.8(72.5)76.079.580.080.581.03.0(32.5)79.584.585.085.586.53.5(88.5)(87.5)95.597.098.099.04.0(95.0)10.51081101124.5(101)1501191221255.0(107)1231291331375.5(131)1381431496.0(138)14615216
