The invention provides an outgoing line terminal and an inflatable cabinet with the outgoing line terminal. The outgoing line terminal comprises an electric conductor, an insulator, a temperature sensor packaged in the insulator, a signal transmitter and a mutual inductance power supply device; and a sensing part of the temperature sensor is in temperature sensing contact with the electric conductor and is electrically connected with the signal transmitter, and the mutual inductance power supply device is arranged outside the electric conductor in a sleeving mode and is electrically connected with the signal transmitter so as to supply power to the signal transmitter. According to the scheme, the sensing part of the temperature sensor is in contact with the conductor to accurately detect the temperature of the conductor. The mutual inductance power supply device supplies power to the signal transmitter, the signal transmitter transmits temperature data in a wireless mode, connection with a low-voltage circuit can be avoided, and the problem of electrical breakdown does not exist.
Description
technical field [0001] The present application relates to the field of power distribution technology, and more specifically, to an outlet terminal of an inflatable cabinet and an inflatable cabinet with an outlet terminal. Background technique [0002] In the field of power distribution technology, the electric energy is decompressed by the high-voltage substation and then output to the inflatable cabinet, and then delivered to the user after further decompression. [0003] The inflatable cabinet belongs to the secondary distribution equipment, and the outlet terminal is used as the output interface of the inflatable cabinet, which is usually connected to the cable by means of a cable shoe. The connection between the outlet terminal and the cable boot is prone to high temperature due to poor contact. Long-term overheating of the connection part will cause insulation breakdown, and the tabs will cause large-scale power outages. [0004] Therefore, the temperature monitoring ...
