Abstract
The utility model relates to an SF6 gas online monitoring system for a high voltage circuit breaker. The SF6 gas online monitoring system for the high voltage circuit breaker is characterized in that the system consists of an SF6 micro water density sensor collecting unit, an online monitoring main IED (Integrated Electronic Device) and a three-way valve. The three-way valve is mechanically connected with a gas filling hole of the circuit breaker while the other end of the three-way valve is connected with the SF6 micro water density sensor collecting unit. The SF6 micro water density sensor collecting unit is connected with the online monitoring main IED through a 485 communication cable and a power supply cable. With the adoption of the utility model, a conventional offline measuring manner which wastes time and labor and pollutes environment can be changed, multiple indexes of SF6 gas can be accurately measured in real time so as to lay a foundation for intelligent construction of a power grid.
Description
Technical field
The utility model relates to a kind of primary cut-out SF6 gas on-line monitoring system.
Background technology
Along with the fast development of China's power industry, the urgency that SF6 broad application and intelligent grid are built, the online comprehensively monitoring of being badly in need of solution SF6 electrical equipment is technological.SF6 gas is because its intrinsic characteristic is comparatively desirable insulation and arc-extinguishing medium at present.But its micro-water content, gas density or the like all can be to the operation of equipment, personnel's safety, electrical network reliably bring direct influence.Therefore be that relevant industries are to one of monitoring of equipment important ingredient to the micro-water content of SF6 electrical equipment, the monitoring of gas density always.
Monitoring to SF6 high voltage electric equipment gas density and micro-water content is that relevant industries are to one of monitoring of equipment important ingredient always.Relevant department has formulated relevant criterion in succession SF6 gaseous mass, particularly micro-water content has been carried out strictness control.The product of SF6 on-line monitoring is more and more now, and what still realize IEC61850 communication interface and fault diagnosis functions also is not a lot of or imperfection.
The utility model content
The purpose of the utility model provides a kind of primary cut-out SF6 gas on-line monitoring system; It can change traditional wasting time and energy and the off-line measurement mode of contaminated environment; Measure SF6 gas many index real-time and accurately, for the intelligence construction of electrical network lays the first stone.
The utility model is realized above-mentioned purpose through following technical scheme: a kind of primary cut-out SF6 gas on-line monitoring system, the little water-mass density sensor acquisition of SF6 unit, on-line monitoring master IED and three-way valve constitute.Mechanical connection is carried out in the tonifying Qi hole of said three-way valve and isolating switch, and the other end is connected with the little water-mass density sensor acquisition of SF6 unit.The effect of this three-way valve is and can guarantees the tonifying Qi operation that gas does not influence isolating switch again of getting of on-line equipment.
The little water-mass density sensor acquisition of SF6 unit is connected with on-line monitoring master IED2 with feed cable through 485 communication cables.Interior circulating technology has been adopted in the sampling pond of collecting unit inside, and the correlation parameters such as little water, density and temperature of SF6 in the measuring equipment realize showing in real time communication and the exchanges data that reaches with main IED in real time.Main IED to data analyze, processing such as fault diagnosis, main IED is connected to optical fiber switch through optical fiber, carries out data communication through the IEC61850 agreement with background data center.
The outstanding feature of the utility model is:
1, circulating technology in the inner utilization of collecting unit significantly improves sampling precision.
2, the passive output of built-in density monitor can be established the moving point value of locking/warning/superpressure.
3, totally-enclosed design, water proof and dust proof, anti-high frequency interference is applicable to indoor and outdoor.
4, multiple Valve joint, maintenance cost is saved in easy installation and removal.
5, sensor is through 485 communications, connect main IED after, main IED through IEC61850 with the background data center communication.
6, high precision and high reliability, parameters such as little water, density, temperature in on-line monitoring SF6 isolating switch or the combined electrical apparatus.
7, the temperature compensation of the pressure of the little water of realization and temperature compensation, density makes little water and density data true and reliable.
8, adopt sensor with self-calibration function.
9, collecting unit can put into operation, withdraw from not influencing under the master status, does not influence the normal operation of main equipment.
10, there is not discharging, environmental protection, economy, safety, reliable.
Description of drawings
Fig. 1 is the block diagram of the described primary cut-out SF6 of the utility model gas on-line monitoring system.
Embodiment
Below through accompanying drawing and embodiment the technical scheme of the utility model is described further.
As shown in Figure 1, the described primary cut-out SF6 of the utility model gas on-line monitoring system is made up of the little water-mass density sensor acquisition of SF6 unit 1, on-line monitoring master IED 2 and three-way valve 3.Said three-way valve 3 carries out mechanical connection with the tonifying Qi hole of isolating switch, and the other end is connected with the little water-mass density sensor acquisition of SF6 unit 1.The little water-mass density sensor acquisition of SF6 unit 1 is connected with on-line monitoring master IED 2 with feed cable through 485 communication cables.
The concrete installation and operation steps:
1. the installation of collecting unit.
2. vacuumize.When being installed, micro-water integrated collecting unit must vacuumize in advance.
3. leak detection.
4. the processing of collecting unit residual moisture
After completion vacuumizes and hunts leak; Collecting unit and threeway inside maybe be also can residual minim moisture; Can insert the high precision dew point hygrometer gas supplementing opening of threeway this moment; Open the content that needle valve in the threeway begins to detect residual moisture, vacuumize once more with threeway and hunt leak and handle till the stable no longer rising of its little water number if little water number is then tackled monitor apparently higher than the little water number in the air chamber.
5. the mobile equilibrium of collecting unit and device interior gas to be detected
After collecting unit formally inserts air chamber; Because SF6 gas needs progressively to reach mobile equilibrium with the gas that newly connects in the equipment cavity in the air chamber; A change curve that earlier rises and afterwards descend will appear in the little water number in the collecting unit, and slowly be reduced to little water number of SF6 gas in the air chamber.Under the normal condition, the time of mobile equilibrium needs about 2-15 days approximately.
6, get into little water of SF6 gas and the continuous on-line monitoring state of density.Data constantly upload to data center through IED.
