Overview

SF6 intelligent dew point meter The instrument automatically enters the measurement state when turned on, and the measurement begins. First, open all the flow valves on the panel, and then adjust the flow rate using the needle valve on the measuring pipeline on the instrument. If the measurement is completed, perform the opposite operation.

Product Details

SF6 intelligent dew point meter

Dear intelligent dew point meter user:

If using this product, please note the following:

1. The instrument automatically enters the measurement state when turned on, and the measurement begins. First, open all the flow valves on the panel, and then adjust the flow rate with the needle valve of the measuring pipeline on the instrument. If the measurement is completed, perform the opposite operation.

2. This device is equipped with a large capacity lithium battery, which can work continuously for more than 10 hours after being fully charged.

When the dew point meter is not used for a long time, there will be some air left in the testing pipeline and chamber. Therefore, during the D test, the high humidity gas in it will affect its testing speed because the moisture in the air needs to be removed before the tested SF6 gas reaches saturation. So we will find that the speed of testing the second SF6 electrical equipment and subsequent measurements will be very fast (3-5 minutes).

When printing data, it is recommended to plug in an AC220V power supply to increase battery life (optional printer).

5. In case of high temperature weather, we suggest arranging the measurement time as early as possible when the temperature is lower in the morning, as higher temperatures can affect the accuracy of the measurement.

Reference standard: DL/T506-2007 "Measurement Method for Humidity of Insulation Gas in Sulfur Hexafluoride Electrical Equipment" of the People's Republic of China's power industry standard

6. Requirements for measuring environmental temperature and humidity

Environmental temperature: 5 ℃~35 ℃ (measured as much as possible between 10 ℃~30 ℃)

Thank you for your cooperation!

1、 Technical features and parameters

1. Technical features

(1) Self calibration: The sensor probe can automatically calibrate the zero point, eliminate system errors caused by zero point and drift, ensure the accuracy of each measurement, and avoid the tedious annual calibration.

(2) Fast gas saving: After starting up and entering the measurement state, the measurement time for SF6 gas dew point is about 2 minutes.

(3) Self locking connector: using German original self-locking connectors, safe and reliable, without air leakage.

(4) Data storage: Designed with a large capacity, it can store up to 200 sets of test data.

(5) Curve function: The large screen curve displays the dew point measurement process.

(6) Clear display: The color LCD screen directly displays dew point, micro water (ppm), ambient temperature, ambient humidity, time, and date.

(7) RS232 interface: can be connected to a PC serial port for data transmission.

(8) Built in power supply: Equipped with a 4Ah rechargeable lithium battery, it can work continuously for 10 hours on a single charge.

Appendix: (Measurement Requirements for Moisture Content of Sulfur Hexafluoride Circuit Breaker)

Test content	Standard (μ l/l, 20 ℃)
The moisture values of the breaking unit and the support unit should be measured separately during the delivery and major repair of sulfur hexafluoride circuit breakers (before overall assembly).	≤150
During the handover, the moisture value of the circuit breaker is measured by the inflation interface at the bottom of the pillar.	≤150
During operation, the moisture content of the circuit breaker is measured by the lower inflation interface of the support pillar. The testing cycle shall be in accordance with the "Pre Trial Regulations".	≤200
During operation, if necessary (such as leakage of the disconnecting unit or disassembly of the disconnecting unit), the water content in the disconnecting chamber of the SF6 circuit breaker should be measured separately at the self sealing joint inside the header.	≤300
