The invention relates to a SF6 density relay meter connector. Comprises a cylindrical shape table body, a connector body and a rectangular solid shape junction box body; A table body with a cylindrical shape comprise a circular dial and a meter needle; The connector body is composed of two physically isolated cable core compartments and a gas compartment. One end of the cable core in the cable core compartment is connected with the auxiliary contact inside the cylindrical shape surface, and the other end of the cable core in the cable core compartment is connected with the wiring assembly inside the rectangular solid shape junction box; A gas pipe is arranged in the gas compartment so as to communicate with the gas pipe inside the cylindrical shape table and the gas pipe of the high-voltage electrical equipment. The connector body of the invention realizes that the connector body and the cable core wire of the meter are combined into one, the cable core wire is hidden in the compartment of the connector, the volume of the meter is reduced, and the cable core wire is avoided to be exposed. At the same time, a special terminal box body is arranged at the bottom of the connector, which is used for packaging and protecting the meter aviation plug from moisture.
Description
technical field [0001] The present invention relates to SF for high voltage electrical equipment in power systems 6 The structure of the gauge joint of the density relay is also applicable to the structure of the gauge joint of other gases (such as N2), specifically a kind of SF 6 Density relay meter connector. Background technique [0002] In power system, in SF 6 Gas-insulated high-voltage electrical equipment is very extensive, and a SF is usually installed in these equipment 6 Density relay meter, this kind of meter is designed with a certain number of auxiliary contacts, which are used to send signals to remind the staff to deal with them in time and to block related equipment. The connection between these meters and high voltage electrical equipment needs to be done by installing joints. [0003] Disadvantages of existing technology: [0004] Existing SF 6 The density relay meter is connected to the main body of the electrical equipment through a special joint, a...
