DETAILED DESCRIPTION

[0015] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementations:

[0016] like Figure 1 As shown, an online detection device for the temperature of an intermediate frequency cabinet includes an intermediate frequency cabinet 1, in which a plurality of rectifier thyristors 3, inverter thyristors 4 and reactors 5 arranged side by side are installed through a mounting frame 2, and temperature measuring optical fibers 7 electrically connected to an optical temperature measuring host 6 are bonded to the plurality of rectifier thyristors 3, inverter thyristors 4 and reactors 5, and the temperature measuring optical fibers 7 bonded to the plurality of rectifier thyristors 3 and inverter thyristors 4 are arranged and fixed by a cable organizer 8.

[0017] like Figure 2 As shown, the cable organizer 8 includes a wire laying groove 9 arranged on the top of the rectifier thyristor 3 and the inverter thyristor 4 arranged side by side. The wire laying groove 9 mainly plays the role of arranging the temperature measuring optical fiber 7 in the intermediate frequency cabinet 1 to prevent the remaining part of the temperature measuring optical fiber 7 from being exposed inside the intermediate frequency cabinet 1, so that the temperature measuring optical fiber 7 is neat and clear. A plurality of branching holes 10 are opened at the bottom of the wire laying groove 9. The branching holes 10 can lead the corresponding temperature measuring optical fiber 7 downward. A clamping plate 11 is connected to the bottom of each branching hole 10, and a wire placement groove 12 for placing the temperature measuring optical fiber 7 is arranged on the inner side of the clamping plate 11.

[0018] like Figure 2 As shown, the pressing plate 11 is vertically arranged with the wire slot 9 and its inner side is bonded and pressed with the side of the corresponding rectifier thyristor 3 and inverter thyristor 4. The pressing plate 11 can make the temperature measuring optical fiber 7 fit closely with the rectifier thyristor 3 and inverter thyristor 4.

[0019] like Figure 1 As shown, the temperature measuring optical fiber 7 attached to the reactor 5 is connected and fixed by a binding tape. The number of reactors 5 is small and their volume is large, so it is more reasonable and convenient to bind them with a binding tape. The temperature measuring host 6 is wirelessly controlled and connected to the display 13.

[0020] The implementation principle of an online detection device for medium frequency cabinet temperature in the embodiment of the present application is as follows:

[0021] A plurality of temperature measuring optical fibers 7 are attached to the rectifier thyristor 3, inverter thyristor 4, and reactor 5 in the intermediate frequency cabinet 1. The temperature measuring optical fiber 7 transmits the detected temperature information to the optical temperature measuring host 6. The optical temperature measuring host 6 transmits the real-time monitored temperature signal to the display 13 for display, and performs temperature detection on various devices in the intermediate frequency cabinet 1. The temperature measuring optical fiber 7 has insulation and anti-electromagnetic interference performance, and the probe at the front end of the optical fiber is very small, which is very suitable for thyristor temperature monitoring. In this way, temperature monitoring is relatively simple and convenient, and the temperature detection efficiency of the plurality of rectifier thyristors 3, inverter thyristor 4, and reactor 5 in the intermediate frequency cabinet 1 is greatly improved;

[0022] At the same time, the temperature measuring optical fiber 7 on the rectifier thyristor 3 and the inverter thyristor 4 in the intermediate frequency cabinet 1 is fixed by a cable organizer 8, and multiple temperature measuring optical fibers 7 are wired into the wire groove 9 of the cable organizer 8 as a whole, and then each corresponding temperature measuring optical fiber 7 is led out from the branching hole 10, and placed along the wire groove 12 in the lower clamping plate 11, and bonded to the side of the rectifier thyristor 3 and the inverter thyristor 4 through the double-sided tape on the side of the clamping plate 11, so as to ensure that the temperature measuring optical fiber 7 and its front-end probe are closely fitted to the side of the rectifier thyristor 3 and the inverter thyristor 4, so as to ensure the accuracy of detection, and multiple temperature measuring optical fibers 7 can be reasonably arranged and placed through the arrangement of the cable organizer 8, so that the arrangement of the temperature measuring optical fibers 7 on the multiple rectifier thyristors 3 and the inverter thyristors 4 is clearer, more reasonable and more beautiful.
