VDA-01 SF6 gas density relay calibrator

上市日期: 2016-07-03

 

 

1.The instrument has built-in capsule replaceable gas chamber based on self-owned patent. Its calibration scope covers 0-1Mpa in full scale. Calibration work is stable and smooth and can be finished at one stroke without need of interruption for gas charging.

2. The instrument has built-in capsule replaceable gas chamber and replace static seal with dynamic seal to improve airtightness of the instrument.

3. During calibration, SF6 gas conducts internal circulation without discharge into atmosphere, which is more environment friendly and safer.

4. It boasts dual-seal design consisting of hand valve and self-sealing valve in its structure. It is easy to operate and prevents moisture and air from entering pipe. There is no discharge or leakage of SF6 before and after calibration.

5. Cleaning and charging device has simple structure and is easy to operate. Cleaning and charging reduce mini water and foreign gas content inside it to the minimum level.

6. It can automatically identify normally open type normally close type of density relay. It can calibrate single signal (single alarm, single blocking), single alarm single blocking and single alarm dual blocking density relay.

7. It can conduct off-line calibration. It is equipped with a full set of transition adaptor. Density relay of most switch models can receive onsite online calibration without being detached.

8. It has engineering plastic casing, which is beautiful and solid with high protection class.

VDA-01 SF6 gas density relay calibrator is a fully automatic intelligent SF6 gas density relay calibrator. It adopts embedded microprocessor and totally enclosed SF6 gas circulation system to conduct performance calibration on various SF6 gas density relays, normal temperature pressure gages and P20 pressure gages. The calibrator is used in production, maintenance and monitoring of SF6 gas products and is especially applicable in power system to provide convenience in production and safe running of SF6 electric products.
