The invention discloses a temperature detection device and a detection method of an intelligent electric energy meter connector. The detection device includes a temperature measurement component. machine, the host computer is also connected with the current riser; the temperature measurement assembly includes an electric energy meter housing, and a plurality of vertically arranged metal meter tail holes are installed side by side on the outside of the electric energy meter casing, and the metal meter There are intervals between the tail holes, and the bottom of the tail hole of the metal meter has a standard hole matched with the tested connector, and the opening of the standard hole is exposed at the bottom of the electric energy meter housing; the metal meter tail There is also a temperature acquisition unit installation hole on the top of the hole. The temperature sensing head is buried in the tail hole of the metal meter, so that it can fully contact with the electric energy meter connector when measuring the temperature, and directly replace the connector when measuring again, which improves the accuracy and speed of the test.

The invention relates to a diagnosis method of a low temperature plasma density parameter at an atmospheric pressure, and belongs to the field of plasma. A series of problems that the traditional diagnosis method of plasma has low precision, poor efficiency, higher environmental requirements, short service life, higher cost and the like in the measuring process are solved. The method comprises the following steps that: 1. the gas pressure drop Ug(t) in a discharge channel is detected by a voltage transformer; 2. the conduction current jc (x, t) is detected by a current transformer; 3. the total discharge current JT is obtained according to the gas pressure drop Ug (t) in the discharge channel obtained from a step 1 and the conduction current jc (x, t); 4. the plasma density n (t) is obtained according t the total discharge current jT obtained from a step 3; and 5. the discrete plasma density nm +1 (t) is obtained so as to achieve the diagnosis of the plasma density parameter.
