Description

Cable plug with temperature detection
Technical field
The utility model relates to a kind of cable plug with temperature detection.
Background technology
In electric power system, high-tension line plays extremely important function served as bridge, and it is carrying high-tension electric current, in case therefore security incident appears in high-tension line, just very likely causes the paralysis of whole electric power system.In causing many reasons of high-tension line security incident, because the security incident that the cable joint loose contact causes is the most common.Owing to the cable joint loose contact causes the principle of security incident as follows: in the high-tension line running, the cable joint loose contact, the resistance at cable joint place is increased gradually, temperature raises gradually, serious meeting causes cable joint to cross cause thermal damage, even catching fire, just very likely develop into security incident such as untimely processing; Hence one can see that, as long as the temperature of real-time detection streamer joint is found the cable joint that temperature raises as early as possible, just can in time fix a breakdown, and guarantees the normal operation of high-tension line, prevents the generation of security incident.
Up to now, existing cable joint temp measuring method roughly can comprise:
(1) contactless temperature-measuring: all temperature are not all launched infrared ray for the object of absolute zero, and ultrared wavelength and temperature are inversely proportional to, as long as measure the ultrared wavelength that certain is a bit launched, just can know the temperature value of this point; This temp measuring method need to will be measured the temperature transducer of Infrared wavelength over against point for measuring temperature, near because the limited space the cable joint, be difficult to find the position over against the wavelength of cable joint and suitable installation infrared line, so this temp measuring method is not suitable for the thermometric to cable joint.
(2) contact temperature-measuring: temperature transducer is directly contacted with the point for measuring temperature of cable joint, and gather the temperature signal of point for measuring temperature by temperature transducer, thereby obtain the temperature value of this point for measuring temperature; This temp measuring method efficiently solves the temperature transducer inconvenience installation question of above-mentioned contactless temperature-measuring.Disclose a kind of for the method for the online early warning of distribution switchgear cabinet female connector temperature anomaly on September 17th, 2003 such as Chinese patent literature CN 1442938, utilize special-purpose temperature data acquisition device on the outer surface of switch cubicle bus-bar room and cable vault's back shroud respectively the surface temperature rise value of selected regulation point carry out the automatic cycle detection, automatically gather the corresponding temperature rise value data in these positions in the switch cubicle running, by computer the temperature rise value data that gather and relevant result of calculation and basic data and firsthand information are carried out check analysis again, draw whether normal conclusion of the tendency of temperature rise value data and relevant result of calculation and absolute value, exceptional value and the ANOMALOUS VARIATIONS of temperature rise value data and relevant result of calculation are sent early warning.Temperature sensor in the temperature data acquisition device is arranged on the housing of switch cubicle.But for traditional cable plug and since the main material thermal transmission coefficient that adopts lower, cause the interior outside temperature difference larger, contact temperature-measuring is had very large time-delay and deviation.
And the wired and wireless dual mode of the signal of contact thermography technology transmission.Existing wireless temperature measuring device is that the temperature probe that will temperature transducer be housed integrates with the temperature survey transmitting element that wireless sending module is housed, corresponding temperature probe is general-purpose interface, as long as temperature probe is fixed on the point for measuring temperature of cable joint by binding or bonding method, just can carries out thermometric to cable joint.
In the technique scheme, there are the following problems at least:
The first, existing wireless temperature measuring device is fixed to temperature probe on the point for measuring temperature of cable joint by binding or bonding method, not only be not easy to installation and maintenance, and can not guarantee that temperature probe contacts with cable joint closely, might make measurement result deviation occur, the accuracy that impact is measured.
The second, existing wireless temperature measuring device all is internal battery, needs periodic replacement.
Three, owing to needing installation personnel directly to finish at high-tension cable in binding or paste operation, thus in the installation Renewal process of existing wireless temperature measuring device, the high-tension line transmission of must stopping power supply, this understands bring a lot of inconvenience to the user.
