Customization XHYS101 Insulation Oil Dissipation Factor and Resistivity Measuring System
Introduction
Insulation Oil Dissipation Factor and Resistivity Measuring System DTL, is designed and manufactured based on GB/T5654-2007 of Liquid insulating material of relative permittivity, dielectric loss factor and DC resistivity measurements. It is used for measuring dielectric dissipation factor and DC resistivity of insulating oil and other insulating liquids. The instrument is characterized by integrated structure, and integrates test cell, temperature controller, temperature sensor, dielectric loss test bridge, AC test power, standard capacitor, high resistance meter, DC high voltage source and other major components. The instrument adopts full digital technology and all of the intelligent automatic measurement, is equipped with large color screen (800*480) LCD display, which each step has prompted the Chinese, the test results can be automatically stored and printed output, so that the operator without professional training will be able to use it proficiently. The main functions and features
1. The test cell used of the three-electrode structure in line with the national standard GB/T5654-2007, with electrode spacing 2mm, can eliminate the effects of the stray capacitance and leakage on dielectric loss test results. The apparatus is equipped with the oil drainage solenoid switch, and we can empty the test cell in case of not removing it and rinse it with the test sample.
2. The instrument adopts the medium frequency induction heating, PID temperature control algorithm. This heating method has the advantages of t non-contact between the test cell and the heating body, even heating, fast speed, convenient control, strict control of the temperature within error range of the preset temperature.
Internal standard capacitor is SF6 gas-filled three-electrode capacitance, and its capacitor dielectric loss and electrical capacity is independent of ambient temperature, humidity and other effects, so that the instrument accuracy can be ensured even after prolonged use.
4. AC test power supply using AC-DC-AC conversion, effectively avoid the fluctuations in mains voltage and frequency on dielectric loss measurement accuracy effect. Even a generator, the instrument can work properly. 5. Perfect protection function; When there is over voltage,over current or high-voltage short circuit, instruments can quickly cut off pressure, and issues a warning message. When the temperature of the sensor failure or not connected, the instrument will also issue a warning message.
6. There is a temperature limiting relay in the medium frequency induction heating furnace. When temperature above 120 degrees, the instrument frees the relay and stops heating. 7. More convenient the experimental parameter is set. Temperature setting range 0~ 125ºC, AC voltage setting range 500~2000V, DC voltage setting range 0~500V.
8. Using of large-screen LCD display, with backlight and clear display. Friendly interface, simply follow the Chinese menu prompt, enter the command, the instrument can be automatically tested. And automatically store and print test results.
9. Built-in real-time clock, the test date and time may be saved, displayed and printed with the test results.
10. Calibration functions of cleaned dry cell. The measurement of dry cell's capacitance and dielectric loss factor can determine its cleaning and assembly conditions. The calibration data is automatically saved and so that it facilitates the calculation of relative permittivity and DC resistivity.
PANEL DESCRIPTION AND OPERATION MATTERS NEEDING ATTENTION 1. Panel description
Instrument operating instructions and matters needing attention
1.The instrument must be reliable grounding, power entrance lead into AC220V power.
2.Open tank cover, and take out the test cell, we should shut the tank cover, when heating and testing the dielectric loss.
3.The cover is protective and when you open it, will interrupt the heating and high pressure. 4.During the test, there is high pressure and high temperature. Do not contact the test cell, cable and socket when the power is electrify and testing.
5.If it appears dead stop faults phenomenon while testing, turn the system back on, and restart the instrument. Use the appropriate power supply cables. Only use the product-specific power supply line in accordance with the product specification. Be right to disconnect and connect. The instrument must be adequately grounded.
In addition to the power line grounding conductor grounding, product shell's grounding columns must be grounded In order to prevent , the grounding conductor must be connected with the ground. Before connecting with the input or output terminals of the product, make sure that the product is properly grounded. Note that rating value of all terminals. To prevent fire or hazard, please note that all rating values and markings in the product. Before connecting this product, please read the product manual in order to further understand the information about rating values. Use the appropriate protective tube. Use only the protective tube in accordance with provisions of this product type and rating. Do not operate when there is any suspicion of failure. If you suspect this product is damaged, please contact our repair staff to check, and do not continue the boot operation. Align the locating slot when the internal electrode into the external electrode. Do not operate in humid environments. Do not operate in explosive environments. Keep the surface clean and dry. Special notice: This instrument has high voltage output, improper use can compromise personal safety, prior to the use of this instrument, be sure to read the instruction manual carefully!
