Description

A new type of direct-acting isolating switch

technical field

The utility model relates to the design field of an isolating switch, in particular to a novel direct-acting isolating switch.

Background technique

At present, the moving contact of the existing isolating switch is rotating, and the volume is large, so it occupies a large space. The linkage between the external terminal and the moving contact is directly clamped on the external terminal after the moving contact rotates. On the one hand, because the moving contact occupies a large space in the switch cabinet when it rotates, the size of the cabinet is limited by the size of the isolating switch during installation, which brings a lot of inconvenience to the miniaturized switch cabinet and affects the miniaturized switchgear. development of.

Contents of the invention

In order to solve the above existing technical problems, the utility model provides a new type of direct-acting isolating switch, which reduces the volume of the isolating switch, achieves the purpose of miniaturization, and meets the needs of modern high-voltage switchgear.

In order to achieve the above object, the technical scheme adopted by the utility model is as follows:

A new type of direct-acting isolating switch, which is divided into three stages, each single stage includes an isolating moving contact, an isolating bracket, an isolating static contact and a carriage. On the rod, the slider is fixed with a screw nut, the screw passes through the screw nut and is fixed on the isolation space, the slider is provided with a fixedly connected insulator and a bracket, the isolation moving contact is connected to the bracket through a pin shaft, and the isolation The static contact is fixedly arranged on the isolation bracket.

The bottom of the sliding frame is provided with a positioning sleeve.

The utility model has the advantages of simple structure and convenient operation. It changes the movement mode of the isolating switch into a direct-acting type, greatly reduces the overall volume of the isolating switch, realizes the complete separation of the dynamic and static contacts after the gate is opened, and has a large opening distance for the isolation. The rod and screw nut rocking mechanism reduce the difficulty of adjustment during assembly, the transmission is fast, more stable, flexible and labor-saving.

Detailed ways:

The utility model is described in detail below in conjunction with accompanying drawing and specific embodiment:

As shown in Figure 1, Figure 2 and Figure 3, it is a specific embodiment of the utility model, which is divided into three stages, and each single stage includes an isolated movable contact 1, an isolated bracket 2, an isolated static contact 6 and a carriage 9. The isolation bracket 2 is provided with a guide rod 10, the bottom of the carriage 9 is provided with a positioning sleeve 11, the carriage 9 is arranged on the guide rod 10, a screw nut 8 is fixedly arranged on the carriage 9, and the screw 7 passes through the nut 8 and fixed on the isolation room 2, the carriage 9 is provided with a fixedly connected insulator 3 and a bracket 4, the isolation movable contact 1 is connected with the bracket 4 through the pin shaft 5, and the isolation static contact 6 is fixedly arranged on the isolation bracket 2 superior.

When it is necessary to connect the inlet and outlet ends of the isolating switch, turn the screw 7 clockwise, and the screw nut 8 drives the carriage 9 to move in the direction of isolating the static contact 6, and at the same time drives the isolating movable contact 1 to isolate the static contact 6 direction movement, when the positioning sleeve 11 is in contact with the isolation bracket 2, the isolation movable contact 1 is inserted into the cavity of the isolation static contact 6, and the isolation switch is turned on at this time.

When it is necessary to disconnect the inlet and outlet ends of the isolating switch, turn the lead screw 7 counterclockwise, and the screw nut 8 drives the carriage 9 to move away from the static contact 6, and at the same time drives the isolation movable contact 1 to move from the isolation static contact Pull out the head 6 cavity, when the positioning sleeve 11 is in contact with the isolation bracket 2 on the other side, the air net distance between the isolation movable contact 1 and the isolation static contact 6 reaches 150mm, realizing the disconnection of the isolation switch .
