Embodiment Construction
[0027] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0028] Such as figure 1 and figure 2 As shown, the embodiment of the present invention provides a cable connector for a ring network cabinet, including an insulator 10 and an electrolytic copper rod 20 inside the insulator 10. One end of the insulator 10 is located inside the ring main The internal cables electrically connected to the rods 20, the other end of the insulator 10 is facing the outside of the ring network cabinet, and is used for inserting cables that can be electrically connected to the electrolytic copper rods 20.
[0029] The inside of the insulator 10...

The invention discloses a cable plug connector of a ring network cabinet. The cable plug connector of the ring network cabinet comprises an insulator and an electrolytic copper rod located inside the insulator, wherein one end of the insulator is located inside the ring network cabinet and is used for plugging an inner cable which can be electrically connected to the electrolytic copper rod while the other end of the insulator points towards the outer part of the ring network cabinet and is used for plugging a cable which can be electrically connected to the electrolytic copper rod; the insulator is internally provided with a first collection unit, a second collection unit, a third collection unit and a fourth collection unit; the cable plug connector of the ring network cabinet further comprises a processing unit respectively electrically connected to the first collecting unit, the second collecting unit, the third collecting unit and the fourth collecting unit; the processing unit calculates and outputs a current value Ip, a voltage value U1, a temperature value T and an electrified indication current value A of the cable based on a collected current signal, a collected first voltage signal, a collected second voltage signal and a collected third voltage signal. The scheme not only simplifies the structure of the ring network cabinet, reduces the number of primary equipment in the inner part and improves the use efficiency of the equipment, but also improves equipment reliability.
Description
technical field [0001] The invention relates to a cable connector of a ring network cabinet. Background technique [0002] Existing ring network cabinets, especially SF6 gas-insulated ring network cabinets generally use cable connectors for installing cable plugs. Inside the ring network cabinet, the front half extends out of the ring network cabinet for installing cable plugs. The outside of the cable connector is cast with an insulator, and the inside is equipped with a capacitor for live monitoring of the cables plugged into the insulator. [0003] The existing ring network cabinet insulators only have the function of live monitoring, and the measurement of current and voltage needs to be additionally installed with electromagnetic current transformers and voltage transformers. The installation method of the current transformer is to wear on the three-core cable. If the transformation ratio of the transformer needs to be changed, the cable needs to be disassembled to rep...
