I. Overview Of Instrument
Interelectric damage measurement is a very basic method in the insulation test, which can effectively find the overall damp deterioration of the electrical equipment insulation, and the local defects. It is widely used in electrical manufacturing, electrical equipment installation, handover and preventive test. The dielectric damage measurement of transformer, transformer, reactor, capacitor and casing and lightning arrester is the most basic method to measure its insulation performance. breaks through the traditional bridge measurement method, using frequency conversion power supply technology, using single chip computer, and modern electronic technology for automatic frequency conversion, analog / digital conversion and data operation, fast test speed, high accuracy, automatic digital, easy operation; power using high power switch, output 45Hz 5 H z and 55Hz pure sine wave, automatic pressure, can provide up to 500 V voltage; automatic filter 50Hz interference, suitable for substation electromagnetic interference field test. Widely used in the transformer, transformer, casing, capacitor, lightning arrester and other equipment in the power industryII. Safety Measures
1. Be sure to read this manual carefully before using this instrument.
2. The operator of the instrument shall have the general knowledge of the use of electrical equipment or instrument.
3. The instrument can be used both inside and outside the households, but it should avoid the rain, corrosive gas, excessive dust, high temperature, direct sunlight and other places.
4. The instrument shall avoid severe vibration.
5. Maintenance, care and adjustment of instruments shall be performed by professionals.
6. The instrument ground terminal must be reliably connected to the earth by a grounding cable before any wiring.
7. Due to the high voltage generated by the test equipment, the test personnel must fully and strictly follow the safety operation procedures to prevent others from contacting the high-voltage components and circuits. Personnel directly engaged in the test must fully understand the high voltage test line and the key points of instrument operation. Non-testing personnel must be away from the high pressure test area, which must be clearly indicated by fences or ropes, signs,
8. Adjustment, repair and maintenance of the instrument must be conducted without the power supply. If the power supply must be added, the operator must be very familiar with the high-pressure dangerous components of the instrument.
9. When the insurance pipe is damaged, it must ensure that the same insurance is replaced. It is forbidden to replace different types of insurance or short circuit the insurance directly.
10. When the instrument fails, turn off the power switch and wait for one minute before checking.
III. Performance Characteristics
1. The instrument adopts Fourier transform digital filtering technology to measure capacitance, dielectric loss and other parameters. The test results have high accuracy and are easy to achieve automated measurement.
2. The instrument adopts frequency conversion technology to eliminate 50Hz power frequency interference on site, and reliable data can be measured even in the environment of strong electromagnetic interference.
3. Use a full-touch large LCD display, easy to operate. Full touch LCD screen, super large full graphics operation interface, each process is very clear, operators do not need additional professional training to use. The whole process can be measured with a little touch.
4. Storage data: internally equipped with a calendar chip and large-capacity memory, which can save the detection results at any time, can view the history record at any time, and can print and output. Current times and storage times can be displayed and printed at any time.
5. Scientific and advanced data management: the instrument data can be exported through the U disk, and the data can be viewed and managed on any PC machine through special software.
6. The instrument is easy to operate, and the measurement process is controlled by the microprocessor. As long as the appropriate measurement method is selected, the data measurement can be completed automatically under the control of the microprocessor
7. Integrated model, equipped with standard capacitance and high-voltage power supply, to facilitate field testing and reduce field wiring
8. The instrument measurement accuracy is high and can meet the requirements of oil intermediate loss measurement, so only the oil intermediate loss measurement can be realized with standard oil cup and special test line.
9. Has the low-voltage shielding function of reverse wiring.
10. Be able to do AC pressure resistance test. Convenient for PT, CT secondary AC voltage test, 400V low voltage system to do voltage test.
11. Can identify the frequency of external high voltage power supply of 40Hz~70Hz, and allow the use of power frequency power supply or serial resonance power supply for large capacity and high voltage resonant loss test.
12,With a thermal printer can print output, with a calendar clock, convenient for users to test report, with U disk output.
13,With a computer interface. One computer can control 32 instruments, which can be integrated into the integrated high-voltage test vehicle, realizing measurement, data processing and report output.
14,Ground protection function. When the instrument is not grounded wire or bad grounding, the instrument does not enter the normal procedure and does not output high voltage. Overcurrent protection function, the instrument is not damaged during the test product short circuit or breakdown.
15,Electric shock protection function, when the instrument operator accidentally electric shock, the instrument will immediately cut off the high pressure, to ensure the safety of the test personnel.
