Abstract
The utility model relates to a control device, in particular to a ventilation control device of a gas insulated switchgear (GIS) chamber of a transformer substation, which comprises a microprocessor, a ventilation device, a gas concentration detection device, an admission prompting device and an operation keyboard, wherein the ventilation device, the gas concentration detection device, the admission prompting device and the operation keyboard are respectively connected with the microprocessor. The ventilation control device provided by the utility model has a reasonable structure and is convenient to use and is capable of accurately controlling the ventilation time to ensure that the SF6 gas concentration in the chamber accurately falls below a safety value, and thereby, the polling safety is greatly improved.
Description
Technical field:
The utility model relates to a kind of control device, the especially a kind of GIS of transformer station chamber ventilated control device.
Background technology:
At present, when the staff patrols and examines in the power system, when the staff will enter SF
6Before the power distribution equipment chamber, need to control blower fan earlier and ventilate, the time generally was controlled at about 15 minutes, carried out routine in staff's ability inlet chamber then and patrolled and examined work.But the draft type by staff's evaluation time reduces indoor SF like this
6Gas concentration sometimes because concentration does not drop to below the security value (s), is easy to make and patrols and examines staff's health and come to harm, and has increased the risk of patrolling and examining.
The utility model content:
The utility model provides a kind of GIS of transformer station chamber ventilated control device, and it is rational in infrastructure, and is easy to use, can accurately control the time of ventilation, guarantees indoor SF
6Gas concentration is accurately reduced to below the security value (s), has improved the security of patrolling and examining greatly, has solved problems of the prior art.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: it comprises that microprocessor, ventilation unit, gas concentration detection apparatus, allowance enter suggestion device and operation keyboard, and ventilation unit, gas concentration detection apparatus, allowance enter suggestion device and link to each other with microprocessor respectively with operation keyboard.
The utility model is rational in infrastructure, and is easy to use, adopts to be located at SF in the real-time sensing chamber of indoor gas concentration detection apparatus
6Gas concentration, and this concentration value is delivered to microprocessor compare with the setting security value (s), microprocessor is controlled ventilation unit according to comparative result and is given room ventilation, can accurately control the time of ventilation, guarantees indoor SF
6Gas concentration is accurately reduced to below the security value (s), sends and permits entering cue by permitting entering suggestion device then, but patrol and examine in the prompting staff inlet chamber, has improved the security of patrolling and examining greatly, has guaranteed that the staff's is healthy.
Description of drawings:
Fig. 1 is a theory structure block diagram of the present utility model.
The specific embodiment:
For clearly demonstrating the technical characterstic of this programme, below by the specific embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.
As shown in FIG., the utility model comprises that microprocessor, ventilation unit, gas concentration detection apparatus, allowance enter suggestion device and operation keyboard, and ventilation unit, gas concentration detection apparatus, allowance enter suggestion device and link to each other with microprocessor respectively with operation keyboard.
Described ventilation unit is a blower fan.Described gas concentration detection apparatus is a gas concentration sensor.
Microprocessor is used to coordinate to control the respectively work between the device, comprises receiving the button control information that operation keyboard passes over; Ventilation unit is used for indoor SF
6Gas blows to outdoor, reduces indoor SF
6The concentration of gas; Gas concentration detection apparatus is used for SF in the sensing chamber
6The concentration of gas sends respective concentration information to microprocessor; Permit entering suggestion device and be used to send corresponding sound or flash of light cue, the prompting staff can patrol and examine in the inlet chamber; Operation keyboard is used to import corresponding control information.
During use, need enter SF as the staff
6When work is patrolled and examined in the power distribution equipment chamber, at first transmit a Ventilation Control signal to microprocessor, after microprocessor is received signal, send a signal, transfer current indoor SF to gas concentration detection apparatus by operation keyboard
6The concentration value of gas this concentration value is compared with setting the safe gas concentration value, or numerical value is higher than the setting security value (s), then microprocessor sends a ventilation signal to ventilation unit, after ventilation unit is received the ventilation signal that microprocessor sends, start blower fan and begin to ventilate, indoor SF
6Gas blows to outdoor, reduces indoor SF
6The concentration of gas.The indoor SF that sends back when gas concentration detection apparatus
6The concentration value of gas is lower than when setting security value (s), this moment, microprocessor entered suggestion device transmission one allowance entering signal to allowance, after permitting entering suggestion device and receiving signal, send corresponding sound or flash of light cue, the prompting staff can patrol and examine in the inlet chamber, and microprocessor sends a ventilation stop signal to ventilation unit simultaneously, after ventilation unit is received this signal, close blower fan, stop to ventilate.
The utility model ventilation controller can be according to the real-time indoor SF that detects of gas concentration detection apparatus
6Gas concentration accurately the time of control ventilation, guarantees indoor SF
6Gas concentration is accurately reduced to below the security value (s), sends and permits entering cue by permitting entering suggestion device then, but patrol and examine in the prompting staff inlet chamber, has improved the security of patrolling and examining greatly, has guaranteed that the staff's is healthy.
The utility model does not describe part in detail, is those skilled in the art of the present technique's known technology.
