一种高抗振气体密度继电器
摘要：
本发明公开一种高抗振气体密度继电器。密度继电器包括：外壳、第一波纹管、第二波纹管、微动开关、弹簧、信号调节机构，第一波纹管的一端固定在外壳内壁上，且与气体绝缘设备连通，第一波纹管的另一端与第一密封件密封连接；第一波纹管、第一密封件、外壳及气体绝缘设备形成第一密封腔体；第二波纹管的一端与第一密封件密封连接，第二波纹管的另一端与第二密封件密封连接，第一波纹管、第一密封件、第二波纹管、第二密封件及外壳形成充有补偿气体的第二密封腔体；对应微动开关设置的信号调节机构与第一密封件连接，弹簧的一端连接于信号调节机构与第二波纹管的连接部，弹簧的另一端固定在弹簧固定座上。所述密度继电器的抗振性能好，可靠性高。
摘要（英）：

The invention discloses a high anti-vibration gas density relay. The density relay comprises a casing, a first bellows, a second bellows, a micro switch, a spring and a signal adjusting mechanism. Oneend of the first bellows is fixed on the inner wall of the casing, and is communicated with a gas insulation device. The other end of the first bellows is sealedly connected with a first seal member.The first bellows, the first seal member, the casing and the gas insulation device form a first seal cavity. One end of the second bellows is sealedly connected with the first seal member. The otherend of the second bellows is sealedly connected with a second seal member. The first bellows, the first seal member, the second bellows, the second seal member and the casing form a second seal cavityfilled with a compensation gas. The signal adjusting mechanism corresponding to the micro switch is connected with the first seal member. One end of the spring is connected with the joint part of thesignal adjusting mechanism and the second bellows. The other end of the spring is fixed on a spring fixing seat. The density relay has the advantages of good vibration resistance and high reliability.
