The gas-filled cabinet serves as a device in the secondary power distribution line 4 for providing power to the user. The outlet terminal serves as an output interface of the gas-filled cabinet and is usually connected with a cable through a cable shoe. The connection part of the outgoing line terminal and the cable shoe is easy to generate high temperature due to poor contact, and insulation breakdown is caused by long-term overheating, so that a large-area power failure accident is caused.
Such failures in the field of power transmission and distribution, which are subject to a large social range, often result in power outages in areas around several square kilometers. The resolution of such failures is long, usually at least several hours and seriously several days. Therefore, the temperature monitoring of the connection portion of the outlet terminal and the cable shoe is a technical problem to be solved.
In order to solve the above technical problem, an embodiment of the present application provides an outlet terminal and an air charging cabinet having the outlet terminal. Because the conductor of the outlet terminal has high voltage inside, if the sensor is directly contacted with the conductor, and the signal detected by the sensor is led out through a circuit, the problem of electric breakdown can occur. If the sensor does not contact the conductor, the temperature of the conductor at the connection position of the outlet terminal and the cable shoe cannot be directly measured, and the measured temperature is not accurate enough. The inventive concept of the present application specifically includes: the temperature sensor is contacted with the conductor of the wire outlet terminal to directly detect the temperature of the conductor, the mutual inductance power supply device sleeved outside the conductor supplies power to the signal transmitter, and the signal transmitter transmits the temperature signal detected by the temperature sensor in a wireless communication mode, so that the problem of electrical breakdown caused by introducing a low-voltage signal output circuit and a low-voltage power supply circuit is avoided.

Wherein, the insulator 105 is packaged outside the conductor, and the temperature sensor 102, the signal transmitter 103 and the mutual inductance power supply device 104 are packaged inside the insulator 105.
The sensing part of the temperature sensor 103 is directly in temperature sensing contact with the conductor 101, and the temperature sensor 103 directly senses the temperature of the conductor 101 at the connection part of the outlet terminal and the cable shoe.
The mutual inductance power supply device 104 is sleeved outside the conductor 101, when the outlet terminal 100 is connected with the cable shoe 200, alternating current flows in the conductor 101, an alternating magnetic field is generated around the alternating current, the alternating magnetic field can enable the mutual inductance power supply device arranged around the conductor 101 to generate mutual inductance current like a mutual inductor, and the mutual inductance current can supply power for the signal transmitter 202.
The signal transmitter 102 is electrically connected with the mutual inductance power supply device 104, and the signal transmitter 102 is electrically connected with the temperature sensor 103. The mutually inductive power supply 104 is used to provide power to the signal transmitter 102. The temperature sensor 103 collects a temperature signal of the conductive body 101 and transmits the temperature signal to the signal transmitter 102. The signal transmitter 102 processes the temperature signal and transmits the processed temperature signal to the outside by wireless.

In order to prevent the high voltage from being led out by the signal output circuit of the temperature sensor 103, the output circuit of the temperature sensor 103 cannot use a low voltage circuit, so as to ensure that the output circuit of the temperature sensor 103 cannot be electrically connected with an external low voltage circuit; therefore, the temperature measurement data collected by the temperature sensor 103 is transmitted out in a wireless transmission mode in the scheme. In addition, the scheme adopts a self-powered mode, and utilizes the mutual inductance power supply device 104 to induce a tiny current as a power supply of the signal transmitter. The electric energy is obtained by only utilizing the current in the conductor 101 without introducing a low-voltage power supply from the outside, and is completely isolated from the outside.
Because the mutual inductance power supply device 104 is used for supplying power and the signal transmitter 102 is used for transmitting temperature data in a wireless mode, the whole outgoing line terminal 100 is closed on a single-phase high-voltage potential, just as a bird can stay on an exposed high-voltage line, the outgoing line terminal 100 and a low-voltage circuit cannot form a loop, the potentials of all parts of the outgoing line terminal 100 are the same, the voltage drop among the temperature sensor 103, the signal transmitter 102 and the mutual inductance power supply device 104 is small, and the temperature sensor 103, the signal transmitter 102 and the mutual inductance power supply device 104 cannot be broken down electrically.
