Embodiment Construction

[0010] Such as figure 1 , figure 2 as shown, figure 1 It is a structural schematic diagram of a high-voltage cabinet safety device proposed by the present invention; figure 2 for figure 1 Schematic diagram of the structure of the first cam and the second cam.

[0011] refer to figure 1 with figure 2 , a high-voltage cabinet safety device proposed by the present invention includes a handle 1, a linkage mechanism, and a power switch. The linkage mechanism includes a first linkage lever 2, a second linkage lever 3, a first cam 4, and a second cam 5. The handle 1 and The first linkage lever 2 is connected and can drive the first linkage lever 2 to rotate. A linkage piece 7 is arranged between the first linkage lever 2 and the second linkage lever 3. The second linkage lever 3 can transmit power through the linkage piece 7 and follow the first linkage lever 2 A linkage lever 2 rotates synchronously, the second cam 5 is connected with the rotary lever 6 of the power switch,...

Abstract

The invention discloses a high-voltage safety cabinet device, comprising a handle, a linkage mechanism and a power supply switch; the linkage mechanism comprises a linkage rod and a cam, which are connected; the cam rotates along with the rotation of the linkage rod; the linkage rod is fixedly connected with the handle; the power supply switch is positioned below the cam; the power supply switch as a driven part and the cam form a cam mechanism; the handle has a first position, a second position and a third position; in the process that the handle rotates to the second position from the first position, the cam protrudes the power supply switch to cut off a power supply; in the process that the handle rotates to the third position from the second position, the cam is not contacted with the power supply switch. The high-voltage safety cabinet device is simple in structure, enables the overhaul process of the high-voltage cabinet to be safe and prevents overhaul personnel from being harmed.

Description

technical field [0001] The invention relates to a safety device for a high-voltage cabinet. Background technique [0002] The high-voltage cabinet mainly has functions such as overhead incoming and outgoing lines, cable incoming and outgoing lines, and bus connection. It is used for on-off, control or protection in power system power conversion and consumption. It is an important power transmission and transformation equipment and is widely used in the field of electric power industry. use. When the high-voltage cabinet fails and needs to be repaired, during the repair process, because the high-voltage environment is extremely dangerous, it is necessary to ensure that the power is turned off. In the existing high-voltage cabinets, the power switch is mainly turned off manually. After the power is turned off, when the power switch is touched by a misoperation, the power will be turned on, which poses a safety hazard. Contents of the invention [0003] In order to solve th...
