summarize
SF6 density relay calibrator (Winfoss-A22) is an intelligent automatic SF6 emission free environmental protection type built-in airbag density relay calibrator. The instrument adopts single-cycle instruction microcomputer technology, the running speed is 10 times that of ordinary single chip microcomputer. It can verify the SF6 density relay with pointer contact output and intelligent current output on the spot, and capture the action of density relay in real time by interrupt mode, so the measurement of the instrument is more accurate and timely. This instrument is a portable calibration instrument that can carry out standard conversion of SF6 gas pressure at any ambient temperature, and it can also check SF6 density meter and pressure gauge.
In a closed container, the SF6 gas pressure at a certain temperature can represent the density of SF6 gas. It is customary to take the SF6 gas pressure at 20℃ as the standard value. In the field verification, under different ambient temperatures, the measured pressure value should be converted to its corresponding pressure value at 20℃ to judge the performance of SF6 density relay.
Winfoss-A22 Emission-free environment-friendly SF6 density relay calibrator can complete the verification process automatically, without any pollution to the environment, easy to use and accurate measurement, Chinese menu operation is simple and clear.
Functional characteristics
l The instrument has built-in capsule replacement gas chamber, the calibration range covers the full range of 0-1Mpa, the calibration process is smooth and smooth, and it is completed in one time without interrupting the air replenishment, and SF6 gas is zero emission during the whole calibration process.
l Capsule replacement air chamber is built into the instrument to achieve static seal instead of dynamic seal and improve the sealing of the instrument.
l During the verification process, SF6 gas is circulating-no emission to the atmosphere, more environmentally friendly and safer.
l The structure adopts double seal design of hand valve and self-sealing valve, which is easy to operate and can prevent water and air from entering the pipeline. There is no SF6 emission and leakage before and after verification.
l Air replenishing device has simple structure and easy operation. Cleaning and replenishing the air can minimize the internal water and impurity gas content.
l can automatically identify density relay normally open type and normally closed; Can verify single signal (single alarm, single block), single alarm single block and single alarm double block density relays.
l Equipped with a full set of transition connectors, the density relays of most switch models can be verified on-site online without disassembly

Check principle
The pressure of the gas enclosed in the container changes with the temperature,In order to have a common standard to compare,We usually put20The relative pressure value of ℃ is used as the standard value. When the density meter is checked, it is converted to the corresponding relationship between pressure and temperature20The equivalent pressure value at ℃,And then compare.
l Block return value check:
When the SF6 density relay needle is zero, the relay is charged at a slow and uniform speed. When the SF6 density relay emits a locking action, the pressure value at the ambient temperature is recorded and converted to the equivalent pressure value at 20℃, which is the locking return value of the SF6 density relay.
l Alarm return value check:
The SF6 density relay is charged at a slow and uniform speed. When the SF6 density relay sends an alarm action, the pressure value at the ambient temperature is recorded and converted to the equivalent pressure value at 20℃, which is the alarm return value of the SF6 density relay.
l Overpressure recovery value check:
Charge the SF6 density relay at a slow and uniform speed. When the SF6 density relay sends an overpressure signal, it starts to deflate the SF6 density relay at a slow and uniform speed. When the relay overpressure alarm signal is sent, record the pressure value at the ambient temperature at that time and convert it to the equivalent pressure value at 20℃. This equivalent pressure value is the overpressure recovery value of the SF6 density relay.
l Alarm value check:
At ambient temperature, when the pressure value in the SF6 density relay is higher than the alarm recovery value, it starts to release gas at a constant speed and slowly. When the SF6 density relay sends an alarm signal, the pressure value under the ambient temperature at that time is recorded and converted to the equivalent pressure value at 20℃, which is the alarm value of the SF6 density relay.
l Blocking value check:
The SF6 density relay is vented at a slow and uniform speed. When the SF6 density relay sends a locking signal, the pressure value at the ambient temperature is recorded and converted to the equivalent pressure value at 20℃, which is the locking value of the SF6 density relay.
l Overpressure check:
