KMJ SF6 Gas Density Relay
It is applicable for monitoring the SF6 gas density in a sealed vessel. It can show gas density values on the site. When the gas density reaches the preset value, the contact-making device will send alarm and control signals. It can be widely used in electric equipment including SF6-insulated composite apparatus, circuit breakers, pole-mounted switches, transformers and mutual inductors. It provides solutions for new construction of transformer substations and inteligent reconstruction of existing transformer substations.

Working Mechanism
We take the SF6 gas pressure value under 20C as the representative value of its density and also as the scale value. When the ambient temperature changes, the temperature compensation elements will compensate for the gas pressure change caused by the temperature change. Therefore, as long as the SF6 gas density remains unchanged, the indication value of the density meter will keep the same .When SF6 gas is filled into the sealed vessel or the gas changes, pressure sensing elements will make displacement which is converted into the indication value through the drive mechanism. When the ambient temperature change induces the indication value change, the temperature compensation elements will make compensation and correction.
KMJZ SF6 Gas Auto Calibration Density Relay
The product is applicable for monitoring the density of SF6 gas in sealed vessels. It can display gas density value on the site.
When the gas density reaches the preset value, the contact-making device will send an alarm and control signals. Gas fl, micro-water test and calibration can be implemented without removal of the SF6 gas density relay so as to prevent unnecessary leak of SF6 gas during these procedures. It can be widely used for composite apparatus, circuit breakers, pole-mounted switches, transformers, mutual inductors and other electric equipment. It provides solutions for new construction of transformer substations and intelligent reconstruction of existing transformer substations.
1. Electric contact switch design realizes accurate and reliable SF6 gas monitoring functions.
2. With temperature compensation, the compensation performance is stable and the detection precision is high.
3. On-site display values and output contact signals are not affected by external conditions including the altitude and ambient temperature change.
4. Core elements are made of imported materials with high precision.
5. Good shockproof performance.
6. There are three contact groups at most, which can realize several options including overpressure alarm, double alarm or double lock and make the monitoring safer and more reliable.
7.Gas fill, micro-water test and calibration can be implemented without removal of the SF6 gas density relay, making it easy for on-site staff to conduct micro-water test and gas supplementand avoiding the seal face and seal ring damage arising from removal.
8.304 stainless steel is adopted for the sealed case, which prevents both moisture and corrosion.
