Abstract
The invention provides an on-line monitoring sampling system for sulfur hexafluoride gas. The on-line monitoring sampling system is characterized by comprising a filter, an electromagnetic valve, a depressurizing valve, a flow sensor, a sulfur hexafluoride decomposition product detector, a first one-way valve, a cylinder, a second one-way valve and an electric pushing rod, wherein one end of the filter is connected with electrical sulfur hexafluoride equipment, and the other end of the filter is connected with a gas inlet of the sulfur hexafluoride decomposition product detector through the electromagnetic valve, the depressurizing valve and the flow sensor in sequence; a gas outlet of the sulfur hexafluoride decomposition product detector is connected with the cylinder and the second one-way valve respectively through the first one-way valve; the other end of the second one-way valve is connected with the electrical sulfur hexafluoride equipment; a piston rod of the cylinder is fixedly connected with the electric pushing rod. According to the on-line monitoring sampling system, the high-pressure sulfur hexafluoride gas in the electrical equipment can be continuously and stably sampled, and the detection reliability of the sulfur hexafluoride decomposition product detector is ensured; after detection is finished, the sulfur hexafluoride gas can be re-filled into the equipment for cyclic utilization, so that the zero emission of tail gas is realized.
Description
Technical field
The invention provides a kind of sulfur hexafluoride gas on-line monitoring sampling system, belong to electrical equipment gas on-line monitoring technique field.
Background technology
Along with the high speed development of power grid construction, China's electrical network develops into large regional grid from city island network, and transferring electricity from the west to the east, north and south supply mutually, the general layout of the large net in the whole nation forms.Power industry was actively used on-line monitoring technique in recent years, carried out State Maintenance, and strengthen the conventionally test of equipment and comprehensively analysis, eliminated some hidden trouble of equipment in time, be that nationwide integrated power grid power supply reliability is significantly improved.But electrical equipment malfunction is the principal element that jeopardizes electric power netting safe running always, in annual unplanned stoppage in transit, there is sizable ratio to be because SF6 electrical equipment malfunction causes.Therefore SF6 electrical equipment obtains the key that reliability service is raising power supply rate.If can realize the on-line monitoring of SF6, the operation conditions of equipment will be conducive to grasp in real time.At present, the domestic correlative study that has started to carry out SF6 on-line monitoring is because most SF6 electrical equipment air chamber volume is little, charge pressure is also had to certain requirement, gas after monitoring can not emit, if and the direct load facility of SF6 on-Line Monitor Device, once break down, be difficult to maintenance.Therefore will realize on-line monitoring first will solve from the problem of apparatus body sampling.
Existing sampler does not all meet the demand of on-line monitoring sampling in the market, over the past two years the rate of growth of SF6 electrical equipment far above before, now on-the-spot in the urgent need to sulfur hexafluoride electrical equipment on-line monitoring sampling system.
Summary of the invention
Order of the present invention is to provide a kind ofly can overcome above-mentioned defect, for the feature of sulfur hexafluoride electrical equipment, the sulfur hexafluoride gas on-line monitoring sampling system of flexible operation.Its technical scheme is:
A kind of sulfur hexafluoride gas on-line monitoring sampling system, it is characterized in that: comprise filtrator, solenoid valve, reduction valve, flow sensor, sulfur hexafluoride decomposition product detector, the first retaining valve, cylinder, the second retaining valve and electric pushrod, one termination sulfur hexafluoride electrical equipment of its middle filtrator, the other end is successively through solenoid valve, reduction valve, flow sensor connects the air intake opening of sulfur hexafluoride decomposition product detector, the gas outlet of sulfur hexafluoride decomposition product detector connects respectively cylinder and the second retaining valve through the first retaining valve, another termination sulfur hexafluoride electrical equipment of the second retaining valve, the piston rod of cylinder is fixedly connected with electric pushrod.
Described sulfur hexafluoride gas on-line monitoring sampling system, electric pushrod employing speed is adjustable, high thrust formula electric pushrod.
The present invention compared with prior art, its advantage is: can realize continuous, the stable sampling to electrical equipment mesohigh sulfur hexafluoride gas, after sampling, gaseous tension can be down to normal pressure, for sulfur hexafluoride decomposition product detector provides representative sulfur hexafluoride sample gas, ensure the reliability that sulfur hexafluoride decomposition product detector detects; Detection finishes rear sulfur hexafluoride gas and can again recharge into equipment and recycle, and realizes the zero-emission that detects tail gas, and the greenhouse effect of avoiding sulfur hexafluoride gas discharge to cause, protect the environment from pollution.
