Problems solved by technology
[0002] Due to the structure of the existing bus duct socket, the copper pins are not directly inserted outside the copper pins corresponding to the phase sequence during the plugging process of the bus main line current and the plug box, so the contact resistance is large and the overload capacity is low. Copper and aluminum materials are directly over-plated, which increases the temperature rise
Due to the different hardness of copper and aluminum materials, the number of times of plugging and unplugging between the two cannot meet the standards and usage requirements. Because the temperature rise of the pins exceeds the standard, it will cause a short circuit, and in severe cases, it will even cause a failure to burn the device

The invention discloses a plug-in structure of a bus slot plug-in box, and relates to the technical field of low-voltage power transmission and distribution. The plug-in structure comprises a groove body, an insulation support and a plug-in box, wherein the insulation support is arranged in the groove body, the plug-in box is arranged above the groove body, heat dissipation holes are formed in the plug-in box, a heat dissipation fan is arranged in the plug-in box, a plurality of bus installation grooves are uniformly formed in the insulation support at intervals, a bus is arranged in each bus installation groove, an insulator is arranged between two adjacent buses, an installation plate is arranged in the plug-in box, a plurality of pin blocks are arranged on the installation plate, a Y-shaped pin is arranged at a lower end of each pin block, a plurality of penetrating holes are formed in a part, corresponding to a bottom surface of the plug-in box, of the installation plate, the Y-shaped pin passes through the penetrating holes and is tightly clamped on the bus, insulation elastic clamping sheets are arranged at two sides of each bus, and lower ends of each insulation elastic clamping sheet are fixed on the insulators. The plug-in structure is stable and reliable, and a situation such as unfavorable contact is prevented.
Description
technical field [0001] The invention relates to the technical field of low-voltage power transmission and distribution, in particular to a plug-in structure of a busbar slot plug-in box. Background technique [0002] Due to the structure of the existing bus duct socket, the copper pins are not directly inserted outside the copper pins corresponding to the phase sequence during the plugging process of the bus main line current and the plug box, so the contact resistance is large and the overload capacity is low. Copper and aluminum materials are directly over-plated, which increases the temperature rise. Due to the different hardness of copper and aluminum materials, the number of times of plugging and unplugging between the two cannot meet the standards and usage requirements. Because the temperature rise of the pins exceeds the standard, it will cause a short circuit, and in severe cases, it will even cause a failure to burn the device. Therefore, need a kind of good stab...
