[0012] A compact integrated switchgear, referring to Figure 1 , Figure 2 , Figure 3 , Figure 4, including a busbar chamber 1, a cable chamber 2 and a main switch 3. The busbar chamber 1 and the cable chamber 2 are cast as one to form an integrated structure. The three integrated busbar chambers 1 and cable chambers 2 are installed on the back of the main switch 3. The busbar chamber 1 and the cable chamber 2 are respectively arranged on the top and the bottom of the main switch 3. A static base 9 and a moving base 10 are arranged in the busbar chamber 1. The static contact of the upper part of the vacuum bubble 5 is installed on the static base 9, and the moving contact of the lower part is installed on the moving base 10. The moving base 10 is connected to the actuator in the main switch 3 through an insulating pull rod 8. The moving base 10 is also connected to the cable connection bar connector 4 through a copper soft connection 11. The cable connection bar 4 is arranged in the cable chamber 2 and connected to the cable connection bar 7 outside the cable chamber 2. The cable connection bar 7 is used to connect external user cables. A lead-out copper bus 6 for connecting to the main busbar on the cabinet top is provided on the upper part of the busbar chamber 1. The front part of the main switch 3 is a self-contained operating mechanism control box. In this embodiment, the main switch adopts the VBS-12 type, and other similar main switches can also be used.

[0013] The busbar chamber 1, the cable chamber 2, the vacuum bubble 5 and the cable connection row 7 of the utility model are integrally formed by casting with resin. When the utility model is used, the moving base 10 equipped with the moving conductive rod of the vacuum bubble 5 is connected to the actuator in the main switch 1 through the insulating pull rod 8. Since the button device of the operating mechanism control box is connected to the actuator, when closing the switch, the closing button of the operating mechanism control box is pressed to connect the power supply of the closing electromagnet in the main switch 3. The energy storage motor in the actuator transmits energy to the energy storage holding mechanism through the connecting rod mechanism and maintains the energy storage through the cam position buckle. The cam mechanism drives the straightening mechanism, the main shaft, and the insulating pull rod 8 to push the moving base 10 of the vacuum bubble 5 to move, complete the internal connection of the vacuum bubble 5, and complete the closing; when opening the switch, the opening button of the operating mechanism control box is pressed to connect the power supply of the opening electromagnet. The energy storage motor transmits energy to the energy storage holding mechanism through the connecting rod mechanism and maintains the energy storage through the cam position buckle.
