Embodiment 1

[0016] See figure 1 , figure 2 1. Insert the high-temperature temperature-sensing rod-shaped detector (4) into the notch of the concave metal wire winding (1). The concave metal wire winding (1) is formed by winding a copper wire with an insulating layer and a cross-sectional area of ​​2 square millimeters for 20 turns and then shaping it. The AC power supply (2) is 12VAC, 200KHz; the high-temperature temperature-sensing rod-shaped detector (4) is a detector specially used for detecting the temperature of the space environment in the painting workshop of the automobile manufacturing industry. The alarm detection temperature is 160°C.

[0017] The detection operation process is as follows: put the high-temperature temperature-sensing rod-shaped detector (4) determined by the experiment into the notch of the concave metal wire winding (1), switch on the AC power supply (2), and within the set time (3 minutes), If the high-temperature temperature-sensing rod-shaped detector (...

Embodiment 2

[0019] See image 3 , install a soft heat insulation pad (7), a soft heat conduction pad (8), and a thermometer (3) in the notch of the concave metal wire winding (1), and the thermometer (3) is a mechanical pointer thermometer (the inspector can visually ), and the rest are the same as in Example 1.

Embodiment 3

[0021] See Figure 4 , Figure 5 , the winding of the concave metal wire winding (1) adopts Figure 4 High temperature resistant multi-strand annealed copper wire (9). The shape of the concave metal wire winding (1) can be made Figure 5 Various shapes shown. All the other are identical with embodiment one.

Abstract

The invention aims to provide a detection device of a high-temperature temperature-sensing rod-shaped detector, which is used in a specific high-risk explosion area. The detection device is characterized in that a concave metal wire winding (1) is connected with an alternating-current power supply (2). According to the device, a principle that heat is generated through electromagnetic induction (the temperature range is 160-190 DEG C) is adopted, a high-temperature temperature-sensing rod-shaped detector (4) is sleeved with the notch of the concave metal wire winding (1), the alternating-current power supply (2) is switched on, and the concave metal wire winding (1) is powered on so that electromagnetic induction is generated, and the high-temperature temperature-sensing rod-shaped detector (4) emits heat. If the high-temperature temperature-sensing rod-shaped detector (4) does not give an alarm all the time, it is proved that the detector fails. Therefore, online detection of the high-temperature temperature-sensing rod-shaped detector in a specific high-risk explosion area can be achieved.

Description

technical field [0001] The invention relates to a detection device of a high-temperature temperature-sensing rod-shaped detector used for detection of fire-fighting facilities. Background technique [0002] High-temperature temperature-sensing rod detectors in fire-fighting facilities are used for fire detection in specific high-risk explosion areas. Its response temperature reaches above 160°C. It is forbidden to use an open flame heating test for the on-site online function test of the high-temperature temperature-sensitive rod detector. No related online test device has been found so far. Contents of the invention [0003] The object of the present invention is to provide a detection device for a high-temperature temperature-sensing rod-shaped detector used in a specific high-risk explosion zone, which is characterized in that: the concave metal wire winding (1) is connected to an AC power supply (2). [0004] Put the high-temperature temperature-sensing rod-shaped det...
