Equipment function

1 and have a comprehensive test function
(1) has the independent or joint adjust the internal temperature, humidity, sunlight (xenon lamp) radiation intensity, get wet in the rain intensity, salt fog settlement etc. Function.
(2) is the perfect time setting control, temperature, humidity control system, and the sunlight light source and regulating system, get wet in the rain and rainfall regulating system, salt fog happened and control system.
(3) can be in accordance with the ChanGongNeng set test procedures, also can set according to the combination experimental operation mode.

Figure 1: equipment test procedures figure

(4) has the press equipment test procedures figure circulating, jump section, keep operating functions, such as real-time visual display running a curve, and can output test curve.
(5) system has self-check function (that is, to run the program combination lock, when the control error will refuse to carry out instruction information), overrun alarm function, fault information display function.
2, cooling function: close partly German valley wheel refrigeration unit (5 P * 2), xenon lamp choose 6.5 kW dc air cooling type.
3, sample frame function
(1) vertical sample rack
But single rotation (positive &negative), can at the same time to test the six insulator, insulator length is 1000 mm (a whole)

Figure 2: sample frame diagram
(2) level sample rack
Article 4 installation level specimens of suspension cable tight device (or so), in order to make the direction specimen level hanging test.
4 and lab temperature control: the forced circulation, balance the wind temperature adjustment wet (BTHC), the refrigeration compressor and heating equipment to perform, temperature control range:-10 ℃ ~ + 60 ℃, the control precision of 0.5 ℃ for +, closed loop control of temperature and black. The standard temperature is a direct measurement of the surface temperature method. Its value than the high temperature 10 ~ 15 ℃.
5, precise humidity control: humidity range: ≮ 30% RH ~ 98% RH, humidity should be in less than 20 min arrived within 98% relative humidity RH, relative humidity precision: + 2% ~ 3%; Closed loop control.
6, irradiance control
1) lighting: 6.5 kW xenon arc lights, 48 cm to simulate the sun radiation (in the full spectrum, including ultraviolet and infrared, visible spectrum distribution).
Radiation: strength meet international lighting commission (C.I.E) test simulated the sun radiation recommend radiation intensity (about 1.12 kW/m2).
2) more than 2000 hours of service life xenon lamp.
3) xenon lamp for dc trigger type. Air cooling, filters.
4) illumination for closed loop control, have automatic compensation function
5) xenon lamp light irradiation strength for 550 ~ 1150 W/m2, controlled by setting (are)
7, salt fog control
But a continuous or cycle spray, salt fog settlement: 1 ~ 2 ml / 80 cm21hr can be adjusted. The salt water density can allocate than (artificial) (5 ~ 10) kg/m3NaCl, fog grain (5 ~ 10) u m, flow rate (0.4 + /-0.1 m3 · h.
8 and the spray control
Shower nozzle number: 12 to 16, the week even decorate, soft connection form, spray Angle can be adjusted, adjustable scope + 60 degrees. Rainfall levels and vertical component (1.0 ~ 1.5) mm/min, rainfall intensity adjustable range (0.8 ~ 2.0) mm/min, time can be adjusted 0 ~ 9999 min.
9, a water purity control function
Pressure: 138 ~ 354 kpa range can be adjusted and purity: 3 ~ 10 PPB, the flow of water: ≮ 30 L/h, water pressure can be adjusted.
10, test voltage
Test exchange (dc) high voltage (highest quartile test voltage 60 kV, capacity: 100 kVA) : through the side hv bushing, introduction inside voltage.
11, insulation requirements
The inner temperature, humidity, and the sunlight (xenon lamp), get wet in the rain, salt fog, high pressure, and other comprehensive test samples of the state shall withstand voltage, won't appear 60 kV breakdown or flash collaterals.
12, test cycle: the whole system can work for a year without interruption.
13, with sewage collection and processing functions.
14, measuring system
(1) leakage current measurement range: 0.1 mA ~ 100 mA or 1 mA ~ 1 A
(2) in the process of test sample spinning on-line monitoring leakage current change, and can draw real-time leakage current change curves;
(3) measurement channels: 16 road single ended channels (8) (including road difference channel 8 leakage current sensor), the total sample rate 250 kS/s,
15, anticorrosive function: all kinds of facilities are in the test with corrosion resistant function.
