HIGHLY SHOCK-RESISTANT SULPHUR HEXAFLUORIDE GAS DENSITY RELAY

摘要

A highly shock-resistant sulphur hexafluoride gas density relay. The relay comprises a signal control part arranged in a case and a value displaying part which is relatively independent from the signal control part. The case comprises a sealed oil chamber (10) which is relatively independent and used for installing the signal control part, and an air chamber (25) which is connected to the oil chamber and used for installing the value displaying part, the oil chamber being filled with a shock-resisting oil (26). The highly shock-resistant sulphur hexafluoride gas density relay of the present invention is free of oil leakage, and has a good shock resistance, high precision, good electrical performance, and long service life.
