Product Description

HVSF-III SF6 Analyzer-Purity & Dew Point & Decomposition 3 in 1

Ⅰ Summary

    The SF6 gas comprehensive analyzer can measure humidity (dew point), purity, and decomposition products in one. The functions realized with several instruments are now integrated in one instrument. One time on-site measurement can complete up to three indication test, which greatly saves the gas in the equipment, saving 1/2 of gas consumption in one measurement, meanwhile reducing the user's workload and improving work efficiency.

    The instrument can also make a combination of measuring humidity (dew point), purity, decomposition products, or measure any of these parameters.

    The instrument adopts color LCD English display, imitating Windows operation interface, real-time display of various parameters, full intelligent operation, massive information storage, built-in rechargeable battery, AC and DC dual-use.

Ⅴ Measurement method

1. Initialization

Turn on the power switch of the instrument, the instrument enters the initialization self-checking process, which takes 8 minutes.

2. Check the power

When using DC power, if the power is too low, please power off, charge  the battery and continue to use it.

3. Preparation

Before measuring SF6 equipment, it is recommended to use SF6 high-purity gas to obtain the purity of the equipment: pass the high-purity SF6 into the equipment, when it is stable, press the full-scale key to take purity full-scale. If the SF6 purity value drifts, you need to take the "tare" operation, press the zero key to take the zero point.

4. Connect SF6 equipment

Close the flow control valve on the instrument panel. Insert one end of the quick connector of the test pipe into the sampling port of the purity analyzer; connect the threaded end of the measurement pipe to the switch connector and tighten with a wrench. Connect the switch connector to the SF6 electrical equipment measurement interface, and tighten with a wrench. Connect the exhaust duct to the air outlet.

5. Start measurement

Adjust the flow valve, adjust the flow to about 0.3 ~ 0.6L/M, and start measuring. The measurement time takes about 7 to 15 minutes, and then each tested object takes 2 to 4 minutes.

6. Store data

After measurement is done, you can save the data in the instrument and press the "OK" key to call up the operation menu. For the specific operation method, see the following chapter.

7. Measuring other equipment

After one measurement is done, close the regulating valve. Remove the connecter from the SF6 electric equipment.

8. End of measurement

After measuring all equipment, turn off the power of the purity analyzer
