Description

Technical Field

[0001] This utility model relates to the field of disconnecting switch technology, and specifically provides a disconnecting switch base. Background Technology

[0002] An electrical control cabinet is a closed or semi-closed metal cabinet that protects electrical equipment. It is equipped with multiple functions such as detection devices, switch control devices, and auxiliary equipment. Electrical control cabinets are generally equipped with a large number of electrical devices such as main circuit boards, relay boards, instrument panels, and power supply lines. These electrical devices must not only comply with the basic specifications of electrical equipment and meet the requirements for normal operation of the power system, but also be easy to use and maintain in daily life. In order to ensure electrical safety and stability, isolating switches are usually installed on electrical control cabinets. Isolating switches are used to isolate the power supply and ensure safety.

[0003] Disconnect switches are widely used in electrical lines in metallurgy, rail transit, photovoltaic power transmission and distribution, and daily power distribution. The base of the disconnect switch is the carrier of all components in the disconnect switch. Its reasonable partition design plays an important role in the installation layout, performance and space utilization of the disconnect switch components. Therefore, how to design a disconnect switch base with reasonable partitioning and high space utilization plays an important role in ensuring the performance of the disconnect switch.

An isolation platform is included between the terminal conductive through hole and the upper contact mounting hole, and an isolation platform is included between the upper contact mounting hole and the busbar contact mounting hole. A front copper busbar receiving groove is formed between the terminal placement base and the second isolation platform. The front copper busbar body is placed in the front copper busbar receiving groove, and the upper contact body is placed in the upper contact mounting hole. The two ends of the front copper busbar body are electrically connected to the terminal body and the upper contact body, respectively.

[0008] Furthermore, the disconnecting switch includes a protective cover located on the base, with an isolation copper busbar at the lower end of the protective cover; a busbar insulating platform is provided at the upper end of the busbar contact mounting hole, and multiple insertion slots for inserting the isolation copper busbar into the insulating platform for conduction are opened; the two ends of the isolation copper busbar are electrically connected to the upper contact body and the busbar body, respectively.

[0009] Furthermore, the lower end of the busbar body is provided with outgoing contacts, and adjacent outgoing contacts are staggered at equal intervals.

[0010] Furthermore, the ground wire leads are staggered at equal intervals.

[0011] Furthermore, the two transverse ends of the isolation platform are provided with base locking holes for locking the terminal protective cover.

[0012] Furthermore, the longitudinal partition includes an outer plate extending to the side of the terminal holder away from the upper contact mounting hole; a downward-facing mounting bracket is included between the outer plate and the terminal holder.

[0013] Furthermore, a downward-facing mounting plate is provided on the side of the ground wire lead-out port away from the busbar contact mounting hole.

[0014] Furthermore, the outer sides of both ends of the card holder are provided with base locking holes for locking the base onto the disconnector mounting plate.
