detailed description

The specific implementation of the present utility model will be described in further detail below through the description of the best embodiment with reference to the accompanying drawings.

The utility model is a switchgear with an auxiliary switch. The installation method of the auxiliary switch can be linked with the disconnector body. As shown in Figure 1, the switchgear includes a disconnector body. The auxiliary switch 5 is installed on the disconnector body. There is a large shaft 1 driven by the driving mechanism to control the opening and closing of the switch. The positioning sleeve 2 is provided on the large shaft 1. The extension end of the auxiliary switch 5 is provided with a connecting block 4. The positioning sleeve 2 is connected to the connection through the connecting rod 3. on block 4. When the isolating switch is closed, it passes through the positioning sleeve 2 installed on the main shaft 1 of the isolating switch, and then through the connecting rod 3 connected to the positioning sleeve 2, the connecting rod 3 is connected with the connecting block 4 on the auxiliary switch 5, and connected The action of block 4 drives the position of the cam in the control auxiliary switch 5 to achieve closing and opening, so that the opening and closing of the isolating switch drives the switching of the auxiliary switch 5, realizing linkage control, good safety and high reliability.

The switchgear of the utility model has a positioning hole on the large shaft 1, and the positioning sleeve 2 is fixed in the positioning hole through a positioning pin to realize the connection between the positioning sleeve 2 and the large shaft 1. The structure is simple and the connection is convenient.

In the switchgear with auxiliary switch of the utility model, preferably, the connecting rod 3 is an L-shaped structural rod, which has a simple structure and is convenient for connection and transmission. The connecting block 4 has a fan-shaped structure, and a plurality of connecting holes are arranged on the edge of the fan-shaped structure. The relative installation position of the connecting rod 3 and the connecting block 4 can be changed by connecting the connecting rod 3 with different connecting holes, and the opening and closing strokes can be adjusted.

One end of the connecting rod 3 is provided with a thread, and the threaded end is detachably and adjustablely connected in the connection hole through a nut. Use the connecting rod 3 to connect the positioning sleeve 2 and the connecting block 4 on the auxiliary switch 5, first connect the threaded end of the L-shaped structural rod to the connecting block 4 of the fan-shaped structure of the auxiliary switch 5, and connect the other end to the positioning sleeve 2, The rotatable hinge between the connecting rod 3 and the connecting block 4 realizes the linkage between the isolating switch and the auxiliary switch 5 through the coordinated transmission of these three accessories.

The utility model has a switchgear with an auxiliary switch, which simplifies the overall structure of the switchgear and is easy to install. Through the connection of the drive connecting rod, the linkage control of the auxiliary switch and the isolating switch is realized. The opening and closing reliability is high, and the operation is flexible. Strong practicality.

The utility model has been exemplarily described above in conjunction with the accompanying drawings, but the utility model is not limited to the above-mentioned manner, as long as various insubstantial improvements or direct application to other Occasions, all fall within the protection scope of the present utility model.
