Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of isolating switches, in particular to a side-mounted isolating switch. Background Art
[0002] An isolating switch is a switching device that is mainly used for "isolating power supply, switching operation, connecting and disconnecting small current circuits" and has no arc extinguishing function. When the isolating switch is in the open position, there is an insulation distance that meets the specified requirements and an obvious disconnection mark between the contacts; when in the closed position, it is a switching device that can carry the current under normal circuit conditions and the current under abnormal conditions (such as short circuit) within a specified time. It is generally used as a high-voltage isolating switch, that is, an isolating switch with a rated voltage of more than 1kV. Its working principle and structure are relatively simple, but due to its large usage and high requirements for working reliability, it has a great impact on the design, construction and safe operation of substations and power plants. The main feature of the isolating switch is that it has no arc extinguishing ability and can only open and close the circuit without load current.
[0003] The existing side-mounted isolating switch and the operating panel are usually separated, resulting in a large volume, which is not only inconvenient for the staff to operate, but also occupies a lot of space; and the existing side-mounted isolating switch is usually equipped with a spring, mainly to help the contacts generate sufficient pressure when closing, and provide a reaction force to help the contacts separate quickly and reduce the generation of arcs. However, due to the action and reaction force of the spring, the isolating switch is prone to vibration when opening and closing. Since the side-mounted isolating switch is directly installed on the cabinet, the force generated during vibration will directly act on the cabinet, which will affect other equipment in the cabinet. Utility Model Content
[0004] The utility model provides a side-mounted isolating switch to solve the problems raised in the above background technology.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0022] like Figure 1-5 As shown, it is a structural schematic diagram of a side-mounted isolating switch in a preferred embodiment of the utility model;
[0023] In this embodiment, it includes an isolating switch body 1 and an operating panel 2. The isolating switch body 1 also includes a frame 3. An operating lever 4 is rotatably provided on the operating panel 2. The operating lever 4 is fixedly connected to the rotating shaft on the isolating switch body 1 by a fastener. The rotating shaft on the isolating switch body 1 is driven to rotate coaxially by rotating the operating lever 4, so as to operate the isolating switch body 1 to complete the opening and closing action. An opening and closing indicator 5 is fixed on the operating lever 4 by bolts. An operating indicator 6 is provided on one side of the operating panel 2. The operating indicator 6 facilitates the staff to know the opening and closing direction of the isolating switch body 1. A through hole 7 is provided on one side of the operating indicator 6. The through hole 7 is a circular structure. A connecting rod 8 is provided on the other side and is fixedly installed on one side of the frame 3 by bolts through the connecting rod 8. Mounting plates 9 are welded on both sides of the frame 3. Fixing rods 10 are inserted on the top and bottom of the mounting plates 9.

The buffer pad 15 fits with the surface of the cabinet body to further buffer and weaken the vibration force.
[0024] In this embodiment, two ends of the spring 13 are respectively against the upper abutting plate 11 and the lower abutting plate 12 , so that the vibration force generated by the isolating switch body 1 is offset and weakened by the spring 13 .
[0025] In this embodiment, the opening and closing indicator sign 5 can rotate coaxially with the operating lever 4. The words "open" and "closed" are provided on the surface of the opening and closing indicator sign 5, and the words "open" and "closed" are aligned with the through hole 7.
