Description
Technical field
The utility model relates to a kind of ozonesonde, especially designs a kind of bleeder ozonesonde for ring main unit.
Background technology
Along with the development of electric system and the progressively foundation of electricity market, the weak link of distribution network is more and more outstanding, is more and more not suitable with social demand.As the key equipment of distribution network, the safe and stable operation of ring main unit needs to be protected.Therefore, need to monitor its running status, the ring as wherein: ring main unit internal high pressure electric discharge phenomena, need to be monitored.And produce this principle of ozone according to effluve, thus differentiate discharge severity, a good monitoring means of can yet be regarded as according to the concentration value of ozone.Again because ring main unit has and can not be with characteristics such as establishing cabinet by cable, how on the basis meeting the various characteristic of ring main unit, designing rational ozonesonde is the problem that the applicant is devoted to solve.
Utility model content
The purpose of this utility model is to provide a kind of bleeder ozonesonde for ring main unit, without the need to opening cabinet, by bleeding and ensureing the mode of gas flow rate constant, realize the ozone concentration in Measurement accuracy ring main unit, meanwhile, there is the advantage that the life-span is long, cost is low.
The technical scheme realizing above-mentioned purpose is:
For a bleeder ozonesonde for ring main unit, comprise pump-line, solenoid valve, gas flow cell, pressure switch, variable valve, ozone sensor, gas samping pump, single-chip microcomputer, storer, keyboard and display screen, wherein:
One end of pump-line is placed in ring main unit inside, and the other end connects described gas flow cell by described solenoid valve;
It is inner that described variable valve is arranged in described gas flow cell with cutting off;
It is inner that described pressure switch is placed in described gas flow cell, and be connected with described single-chip microcomputer;
It is inner that described ozone sensor is placed in described gas flow cell, and be connected with described single-chip microcomputer;
Described gas samping pump is communicated with described gas flow cell;
Described storer, keyboard and display screen are connected with described single-chip microcomputer respectively.
The above-mentioned bleeder ozonesonde for ring main unit, wherein, described bleeder ozonesonde also comprises the RS485 interface connecting described single-chip microcomputer.
The beneficial effects of the utility model are: the utility model is by arranging that pipeline leads directly to ring main unit inside, sampling pump is utilized to bleed, therefore measure time without the need to opening ring main unit, and, by the layout of gas flow cell, ensure that the isolation in sensor and pressure switch and the external world, extend life-span also more convenient safety.Utilize variable valve to be adjusted to constant rate, obtain higher accuracy.
Accompanying drawing explanation
Fig. 1 is the structural representation of the bleeder ozonesonde for ring main unit of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Refer to Fig. 1, bleeder ozonesonde for ring main unit of the present utility model, comprise pump-line 1, solenoid valve 2, gas flow cell 3, pressure switch 4, variable valve 5, ozone sensor 6, gas samping pump 7, single-chip microcomputer 8, storer 9, keyboard 10, display screen 11 and RS485 interface 12, wherein:

Variable valve 5 is arranged in the inside of gas flow cell 3 with cutting off, always constant for adjusting gas flow, to obtain measurement result more accurately;
It is inner that pressure switch 4 is placed in gas flow cell 3, and be connected with single-chip microcomputer 8, the sidewall of connecting line hermetically passing gas flow cell 3; For measuring internal pressure, and pass to single-chip microcomputer 8;
It is inner that ozone sensor 6 is placed in gas flow cell 3, and be connected with single-chip microcomputer 8, the sidewall of connecting line hermetically passing gas flow cell 3; For measuring ozone concentration, and pass to single-chip microcomputer 8;
Gas samping pump 7 is communicated with gas flow cell 3;
Storer 9, keyboard 10, display screen 11 are connected with single-chip microcomputer 8 respectively with RS485 interface 12; Wherein, keyboard 10 and display screen 11 realize input and output, and RS485 interface 12 realization is mutual with other system (such as: computing machine); Storer 9 is for storing data; In the present embodiment, the AT89CXX series of At mel selected by single-chip microcomputer 8;
In the utility model, gas samping pump 7 works, and solenoid valve 2 is open-minded, and now pump-line 1 is from extracting gases in ring main unit; Single-chip microcomputer 8 receives the force value of pressure switch 4 output and the ozone concentration value of ozone sensor 6 output, display screen 11 shows, and stores in storer 9.
Above embodiment is only for illustration of the utility model, but not to restriction of the present utility model, person skilled in the relevant technique, when not departing from spirit and scope of the present utility model, various conversion or modification can also be made, therefore all equivalent technical schemes also should belong to category of the present utility model, should be limited by each claim.
