Description
Technical field
The utility model relates to a kind of cable for measuring temperature device for air cooling tubes condenser, belongs to air cooling technique field.
Background technology
At present, air cooling generation technology can better solve generating water shortage problem, is widely used in power field.Wherein air cooling tubes condenser is one of key equipment realizing air cooling generating.In the northeast of China, North China, the Northwest, coal resources are abundanter, but water resource is very deficient, and adopting air cooling system every year can saving water resource more than 90 percent than adopting humid-cool system.Wherein, the quality that air cooling apparatus runs is directly connected to the economical and security that power plant runs.
In Air-cooled Unit, the quality that condenser runs is directly connected to the safety of unit, now general measurement means is placed on heat-exchanging tube bundle condensate water header with thermopair to measure condensing water temperature, again measuring-signal is transferred to DCS system, but Air-Cooling Island is very huge, zones of different, the temperature of diverse location may be all different, therefore in order to realize overall monitor, Air-Cooling Island is arranged multiple thermopair measuring point, like this, if adopt existing temperature sensor, not only installation workload is large, wiring is complicated, can not cover wide, and be difficult to ensure Measurement accuracy precision.
Utility model content
The purpose of this utility model is, provides a kind of cable for measuring temperature device for air cooling tubes condenser, and it has easy for installation, wide coverage, easy to use, not fragile and measure the high advantage of precision.
The technical solution of the utility model: a kind of cable for measuring temperature device for air cooling tubes condenser, comprise sheath, wire and heat conduction solid sols, wire is located in sheath, several temperature probes are provided with along its length in sheath, the pin of temperature probe is connected with wire, and heat conduction solid sols is by temperature probe encapsulation and sheath.Sheath mainly encapsulates temperature probe and inner lead, for the protection of temperature probe and inner lead not by F. O. D; Temperature probe has three pins, and three pins connect a wire respectively, and the pin of the same position of all temperature probes is connected on same wire, thus forms bus type cable for measuring temperature.Containing Graphene in heat conduction solid sols, have thermal resistance little, the feature that heat conduction is fast, for sheath enclosed inside temperature sensor, anti-sealing enters wire inside, and increases measuring accuracy and the response time of temperature probe.
Aforesaid in the cable for measuring temperature device of air cooling tubes condenser, each temperature probe is all socketed with a stainless steel sheath.Apply stainless steel sheath in temperature probe junction, increase in cable for measuring temperature forming process tight, improve heat transfer surface area, improve temperature-responsive speed.
Aforesaid in the cable for measuring temperature device of air cooling tubes condenser, be also provided with a steel wire inner core in sheath.Built-in steel wire inner core can improve intensity and the toughness of cable for measuring temperature, can not destroy temperature measuring wire in the technological process of protection packaging simultaneously.
Aforesaid in the cable for measuring temperature device of air cooling tubes condenser, described temperature probe adopts DS18B20 numeric type temperature sensor.Temperature probe, have the DS18B20 numeric type temperature sensor of three pins, measuring accuracy is high, measures fast response time, has built-in chip;
Aforesaid in the cable for measuring temperature device of air cooling tubes condenser, the distance between arbitrary neighborhood 2 temperature probes is 1m ~ 1.5m.
Aforesaid in the cable for measuring temperature device of air cooling tubes condenser, the distance between arbitrary neighborhood 2 temperature probes is 1.2m.
Compared with prior art, temperature sensor is set directly on wire by the utility model, a cable for measuring temperature only need be used just easily can to measure the temperature of each air cooling tube bank, thus learn the vapor (steam) temperature in tube bank, without the need to arranging support, without the need to manual operation, have that wiring is simple, wide coverage and a high advantage of measuring accuracy.
Cable can be made not fragile by arranging wire rope inner core in sheath, extending its serviceable life, can increase in cable for measuring temperature forming process tight by arranging stainless steel sleeve pipe, improving heat transfer surface area, improving temperature-responsive speed.
