Gas density relay overpressure signal implementing and maintaining method

Abstract

The invention discloses a gas density relay or electro connecting pressure gauge overpressure signal implementing and maintaining method. The gas density relay or electro connecting pressure gauge overpressure signal implementing and maintaining method comprises a gas density relay or electro connecting pressure gauge housing, a pressure measuring element arranged inside the housing, a plurality of electro connecting pressure gauge signal contacts, a movement, a point, a dial and a connector. The gas density relay or electro connecting pressure gauge overpressure signal implementing and maintaining method is characterized by applying a signal action maintaining mechanism. Through high innovation, a maintaining mechanism and a reset mechanism are developed according to the gas density relayor electro connecting pressure gauge overpressure signal implementing and maintaining method to achieve an electric equipment arc overpressure alarming function. When striking arc and being high in pressure, electric equipment can issue overpressure alarming, and when the electric equipment stops striking arc and returns to normal pressure, overpressure alarming signals can be maintained so thatoperators can detect arcing of the electric equipment for timely processing and further ensuring safe power operation.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a method for maintaining an overpressure signal of a gas density relay, 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, e...

Problems solved by technology

And when the arcing of electrical equipment ends, its pressure will decrease, and when it returns to normal, its alarm signal will disappear at this time, and it will be difficult to find when the operating personnel are not on site, and it is difficult to ensure the safe operation of electric power, so innovation is urgently needed
