Abstract

The invention provides an SF6 inflating device of SF6 electrical equipment. The SF6 inflating device comprises an SF6 gas tank, a first electromagnetic valve, a first pressure detector, a first controller, a second electromagnetic valve, a second pressure detector and a second controller. The first controller is used for inflating the SF6 electrical equipment through an inflating pipeline with the utilization of high-pressure SF6 gas stored in the SF6 gas tank when the pressure value of the SF6 gas in the SF6 electrical equipment is lower than a first preset pressure threshold; the second controller is used for adding external high-pressure SF6 gas into the SF6 gas tank through an gas-adding pipeline when the pressure value of the SF6 gas in the SF6 gas tank is lower than a second preset pressure threshold, the second preset pressure threshold is greater than the first preset pressure threshold, and the inflating pipeline and the gas-adding pipeline are not simultaneously communicated anytime. In this way, the SF6 inflating device can inflate the SF6 electrical equipment automatically.

Description

SF 6the SF of electrical equipment 6inflator
Technical field
The present invention relates to SF 6gas charge and discharge technical field, particularly relates to a kind of SF 6the SF of electrical equipment 6inflator.
Background technique
SF 6(sulphur hexafluoride) gas is a kind of nontoxic, colourless, tasteless, odorless, non-flammable synthetic gas, has the incomparable insulation characterisitic of general electrolyte and arc extinguishing ability, is therefore widely used in SF 6electrical equipment.
At SF 6in the process that electrical equipment uses, work as SF 6sF in electrical equipment 6the force value of gas drops to rating value, needs SF 6electrical equipment is inflated, otherwise can affect SF 6electrical equipment works.The way of prior art is at SF 6electrical equipment arranges pressure gauge, reads manometric force value by human at periodic intervals and judge whether force value drops to rating value.If determine force value to drop to rating value, then by inflating manually.
But most of electric power facility is all that implementation is unattended, so, SF 6when the force value of electrical equipment drops to rating value, cannot learn the very first time, cause and can not inflate in time.And if can not inflate in time, then can cause SF 6electrical equipment non-programmed halt, and then cause power grid accident, there is serious potential safety hazard.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of SF 6the SF of electrical equipment 6inflator, can automatically to SF 6electrical equipment is inflated.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: provide a kind of SF 6the SF of electrical equipment 6inflator, comprises SF 6gas tank, the first solenoid valve, the first pressure detector, the first controller, the second solenoid valve, the second pressure detector and second controller: described SF 6gas tank is for storing high pressure SF 6gas, described SF 6gas tank is communicated with described first solenoid valve and described second solenoid valve, and described first solenoid valve is by gas ducting and described SF 6the inflation inlet of electrical equipment connects, and described second solenoid valve connects for accessing external high pressure SF 6the aerating pipeline of gas; Described first pressure detector is for detecting described SF 6a SF in electrical equipment 6gas pressure value, and by a described SF 6gas pressure value sends to described first controller; Described first controller is for receiving a described SF 6gas pressure value, and at a described SF 6when gas pressure value is lower than the first preset pressure threshold value, controls described first solenoid valve and connect described gas ducting, at a described SF 6when gas pressure value is higher than the first preset pressure threshold value, control gas ducting described in described first solenoid valve shuts; Described second pressure detector is for detecting described SF 6the 2nd SF in gas tank 6gas pressure value, and by described 2nd SF 6gas pressure value sends to described second controller; Described second controller is for receiving described 2nd SF 6gas pressure value, and at described 2nd SF 6when gas pressure value is lower than the second preset pressure threshold value, controls described second solenoid valve and connect described aerating pipeline, at described 2nd SF 6when gas pressure value is higher than the second preset pressure threshold value, control aerating pipeline described in described second solenoid valve shuts; Wherein, described second preset pressure threshold value is greater than described first preset pressure threshold value, and connects when described gas ducting and described aerating pipeline are different at any time.
Be different from the situation of prior art, the invention has the beneficial effects as follows: by SF 6electrical equipment carries out SF 6gas pressure value detects, according to SF 6the size of gas pressure value carrys out Controlling solenoid valve to SF 6electrical equipment is inflated, meanwhile, to SF 6gas tank also carries out SF 6gas pressure value detects, according to SF 6the size of gas pressure value carrys out Controlling solenoid valve to SF 6gas tank carries out aerating, makes SF 6gas tank at any time can to SF 6electrical equipment is inflated, thus can automatically to SF 6electrical equipment is inflated, and ensures SF 6electrical equipment normally works.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention SF 6the SF of electrical equipment 6the structural representation of inflator.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technological scheme in the embodiment of the present invention, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
See Fig. 1, be embodiment of the present invention SF 6the SF of electrical equipment 6the structural representation of inflator.The SF of the present embodiment 6inflator comprises SF 6gas tank 1, first solenoid valve 2, first pressure detector 3, first controller 4, second solenoid valve 5, second pressure detector 6 and second controller 7.
SF 6gas tank 1 is for storing high pressure SF 6gas, SF 6gas tank 1 is communicated with the first solenoid valve 2 and the second solenoid valve 5.First solenoid valve 2 is by gas ducting 21 and SF 6the inflation inlet of electrical equipment 10 connects.Second solenoid valve 5 connects for accessing external high pressure SF 6the aerating pipeline 51 of gas.
First pressure detector 3 is for detecting SF 6a SF in electrical equipment 10 6gas pressure value, and by a SF 6gas pressure value sends to the first controller 4.
