Embodiment

[0035] Embodiment: a kind of portable optical fiber heating test device, its structure is as follows Figure 1-4 As shown, it includes two parts: a portable case 12 and a heating rod 13. The portable case 12 contains common components such as batteries, inverters, chargers, and temperature controllers, and has temperature indication, voltage indication screens, and related cable interfaces. The internal structure of the box need not be described in detail here.

[0036] The heating rod 13 is composed of a shell, a heat insulating sheet and a heat conducting sheet 9 . The shell is divided into upper and lower parts: an upper housing 5 and a lower housing 1 , and the heat insulating sheet is also divided into upper and lower parts: an upper insulating sheet 4 and a lower insulating sheet 2 . The upper casing 5 and the lower casing 1 are connected by a hinge 3, which is convenient for opening without separation. The hinge 3 is installed on the upper casing 5 and the lower casin...

Abstract

The invention relates to a portable optical fiber heating test device and method, and belongs to the related technical field of detection devices. The device part mainly includes an upper shell and a lower shell connected by hinges, the upper shell is fixedly connected with an upper heat insulating sheet, and the lower shell is fixedly connected with a lower heat insulating sheet; the upper heat insulating sheet has a groove , a heating belt is installed in the groove, and the temperature of the heating belt is detected by a temperature measuring probe; the lower heat insulating sheet is provided with a heat conduction sheet for transferring heat from the heating belt, and the heat conduction sheet has a cavity for accommodating an optical fiber. This device can be used in the detection scheme of optical fiber linear temperature-sensing fire detectors in on-site environments such as tunnel cables and outdoor cables, for operators to heat the temperature-sensing optical fiber, which is convenient for on-site verification of the relevant performance of temperature measurement items.

Description

technical field [0001] The present invention relates to the technical field related to detection devices, in particular to a portable optical fiber heating test device and method. Background technique [0002] According to the requirements of "Code for Design of Automatic Fire Alarm System" (GB50116-2013), cable-type linear temperature-sensitive fire detectors should be selected for cable tunnels, cable shafts, cable interlayers, cable bridges and other places or parts, and there is a possibility of external fire sources entering For cable tunnels, linear temperature-sensitive fire detectors should be installed on the upper surface of the cable layer and at the top of the tunnel. The linear optical fiber temperature-sensitive fire detectors should use a temperature-sensitive optical cable to protect a power cable, and should Cabling. [0003] The system judges and locates the fault location and provides pre-alarm by detecting the temperature change of the cable surface. Wi...
