The utility model discloses a
bus temperature monitoring device for a high-
voltage rectifier cabinet, and particularly relates to the technical field of high-
voltage rectifier cabinets, which comprises a
thermocouple which is arranged in the high-
voltage rectifier cabinet and is used for monitoring the temperature of a
bus, and the
thermocouple consists of a compensation end and a measuring end connected to the end part of the compensation end, one end of the measuring end is in contact with a
bus, the outer side wall of the compensation end is connected with an adapter wire, one end of the adapter wire is connected with a thermoelectric force display instrument, an L-shaped plate is arranged on the outer side of the compensation end, and the outer wall of the top of the L-shaped plate is fixedly connected with an insulating support. According to the utility model, the installed
electromagnet is electrified to generate
magnetism to attract a
metal plate or an inner wall in the high-voltage rectifier cabinet, and the shell is taken down after demagnetization after power failure, so that the whole temperature measuring device can be conveniently and rapidly installed and disassembled in the high-voltage rectifier cabinet, and the installation position can be adjusted according to actual needs; and the problem of
monitoring data distortion caused by a contact separation phenomenon is not easy to occur.
