Abstract

The invention discloses an electric contact pressure gauge with contact action holding, or a gas density relay with contact (alarm contact) capable of holding, comprising a casing of the electric contact pressure gauge (or density relay), and a measuring device arranged in the casing. The pressure element, the signal contact of several electric contact pressure gauges, the movement, the pointer, the dial, and the connector are characterized in that it also includes a holding mechanism after the signal action. In particular, through a lot of innovation, a holding mechanism and a reset mechanism have been developed, which can realize the arc overpressure alarm function of electrical equipment. When the electrical equipment arcs and its pressure is too high, it can alarm for overpressure. When the arcing of electrical equipment is over and the pressure is normal, the alarm signal will be maintained all the time, allowing operators to discover the arcing phenomenon of electrical equipment and deal with the electrical equipment in time to ensure the safe operation of electric power.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to an electric contact pressure gauge with contact action holding, in particular to a gas density relay with contact action holding. Through great innovation, it has a holding mechanism and a reset mechanism, which can realize the holding function of the electrical equipment arcing overpressure alarm. That is, when the electrical equipment arcs and its pressure is too high, an overpressure alarm can be issued. When the arcing of electrical equipment is over and the pressure is normal, the alarm signal will be maintained all the time, allowing the operator to discover the arcing phenomenon of electrical equipment, and deal with the electrical equipment in time to ensure the safe operation of electric power. Background technique [0002] At present, the signal mechanism (signal control part) of the sulfur hexafluoride gas density relay used to monitor the equipment, especiall...
