2.capacitor divider (also as a coupling capacitor)
Model: HZTRF600-0.002
Rated frequency: 50Hz-200Hz
Cooling method: ONAN
Level: Level 2
Single capacity: 4000pF
Rated capacity: 2000pF
(Notes:The single capacitor is 4000pF and the rated capacity=single capacity/2=2000pF , two pressure bar will be connected in series)
Rated voltage: 600kV
Nominal partial pressure ratio: 2000/1
Dielectric loss: <0.2%
Temperature coefficient: <0.0004
Over-voltage capability: Over-voltage at 110S at 110% UH (660kV) time shall not cause any insulation damage to the test transformer;
Measurement accuracy: <±1%
Running time: long time
The low-voltage arm withstand voltage is 3kV/1min; the high-low pressure arm is made of the same medium to ensure that the partial pressure ratio of the device is not affected by temperature.
Structure: Insulated housing oil-immersed capacitor structure, consisting of top cover, capacitor body, moving chassis, low-voltage arm, except movable base plate, pressure-proof cover, and other insulation accessories must be less than the partial discharge index at rated voltage. 5pC, the insulation withstand voltage requirement is less than 550kV voltage without abnormal discharge;
Top pressure-receiving hood structure: The pressure-pressure hood is made of high-quality LY2 pure aluminum plate. The welding process adopts the sub-arc welding machine welding process to ensure that aluminum oxidation does not occur in the air for a long time. Its radius of curvature contains 550kV power frequency voltage on the pressure equalization hood. Corona phenomenon does not occur, especially the above-mentioned arrangement of parts requires hot-dip galvanizing after gold processing to prevent iron oxidation of components in the air, which will cause corona discharge after oxidation of the above components.
Digital peak voltmeter
Model: PV2-1
Function: The peak voltmeter is mainly used for voltage measurement of power frequency withstand voltage test. It can measure the power frequency test voltage and true RMS value, so it must have the following functions:
Input voltage range: The input voltage range is 700V, and the indicated voltage peak value / or the true RMS value;
Notes: it refers to the input range of the peak meter. AS per The nominal partial pressure ratio 2000:1 and rated voltage 600Kv, we can calculate that the input voltage value range=600KV/2000=300V. So our parameter 700V can totally meet your demands.
2) this voltage is the actual voltage input by the meter: input voltage = test voltage / partial pressure ratio;
3) Peak recurrence: peak/effective value display selection:
4)voltage display: The voltage display uses a 4-digit half-digit table. Directly display the true rms or peak value of the test voltage. The unit of reading is kilovolts;
5) the ratio setting switch: the switch is a four-digit number, indicating that the transformation ratio can be up to 9999. The test can change the partial pressure ratio of the actual test by the digital button, which can make the measurement data more accurate;
6) the accuracy level is not lower than the level 1 peak voltmeter has the function of measuring RMS, peak, peak / √ 2, and can record (maintain) the voltage value when flashover; system measurement error: in accordance with IEC60060-2;
7) Self-holding function of the discharge voltage value of the overvoltage value at the moment of discharge.
