Abstract
The invention provides SF6 gas leakage detection method and material. A paint which is doped with a temperature-sensitive color-changing material and a lithium-based component is coated on the outer surface of a device filled with an SF6 gas; and when the SF6 gas leakage happens, strong exothermic reaction would occur between the leaked SF6 gas and the lithium-based component in the paint so as to heat the paint up and cause the color change of the temperature-sensitive material, therefore, the leakage and leaking parts can be judged.
Description
Technical field
The invention belongs to power product and material technology field, be specifically related to a kind of SF6 gas leak detection method and material, be particularly useful for the detection of Puffer-type equipment gas leakages such as SF6 switch cubicle.
Background technology
At present, in the SF6 air insulation switchgear, leak, not only influence the operate as normal of equipment, under the extremely bad situation, may cause serious consequence such as open circuit in case gas takes place.
SF6 gas Leak Detection is normally very difficult, needs special equipment and program.In addition, under normal pressure, detect, can only judge whether to leak, can not determine concrete leakage position.
If a kind of method is arranged, the leakage of SF6 gas can be detected, and concrete leakage position can be determined, help equipment is keeped in repair, safeguard its normal operation etc.
Summary of the invention
The object of the present invention is to provide a kind of method and material that can detect the leakage of SF6 gas.
The method cardinal principle that detection SF6 gas of the present invention leaks is: doping responsive to temperature electrochromic substance in coating; Coating is coated in the outside surface of the device that is filled with SF6 gas; Leak if SF6 gas takes place, strong exothermic reaction can take place in the SF6 gas of leakage and the component in the coating, coating is heated up, and cause temperature sensitive material variable color.
Method of the present invention is simple, is easy to realize, and the particular location that detects the leakage of SF6 gas that can be more accurate, convenient follow-up work such as maintenance.
Embodiment
Be described in more detail below most preferred embodiment of the present invention.
The present invention is by using a kind of coating to be coated in to be filled with the outside surface of the device (as SF6 air insulation switchgear) of SF6 gas, because the poor activity of SF6 own is difficult to directly and other material generation metachromasias, so the employing indirect method.Among the present invention in coating doping responsive to temperature electrochromic substance and lithium base component.
When the leakage of SF6 gas took place, strong exothermic reaction can take place in the SF6 gas of leakage and the lithium base component in the coating, coating is heated up, and cause temperature sensitive material variable color.And preferably the temperature sensitive material of the permanent variable color of possibility is judged whereby and is leaked and the position.
Claims (3)
1. one kind is detected the method that SF6 gas leaks, and it is characterized in that: doping responsive to temperature electrochromic substance in coating, and coating is coated in the outside surface of the device that is filled with SF6 gas; When the leakage of SF6 gas took place, themopositive reaction can take place in the SF6 gas of leakage and the component in the coating, coating is heated up, and cause temperature sensitive material variable color.
2. one kind is detected the material that SF6 gas leaks, and it is characterized in that: comprise the responsive to temperature electrochromic substance.
3. the material that detection SF6 gas according to claim 2 leaks is characterized in that: also comprise lithium base component.
