Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a power distribution cabinet with a separation switch that prevents accidental touching. Background Art

[0002] In the power system, closing the circuit is to merge two separate contacts into one contact to energize the circuit, such as the attached Figure 2 As shown, at this time, the two conductive sheets are respectively connected to the positive and negative terminals of the wires, and the conductive block is pushed to the position where the two conductive sheets are in contact, so the circuit is energized, and the disconnector separates the contacts to disconnect the circuit. Nowadays, manual rotary dial switches are often installed on high-voltage distribution cabinets to control the connection and disconnection of the distribution cabinet disconnector. However, there are still shortcomings in the rotary dial switches used in high-voltage distribution cabinets. When the electrical switch is turned on or off, it is inevitable that the body will accidentally touch it, causing the switch to be opened or closed by external force. The prior art usually installs an anti-accidental touch device to avoid the occurrence of accidental touch.

[0003] In order to solve the above technical problems, a Chinese invention patent with authorization announcement number CN113539706B discloses a switch structure of a high-voltage distribution cabinet, including a rotary handle, an arc plate and a limit block. Buttons are arranged on both sides of the rotary handle. After pressing the button, the C-shaped buckle is driven to slide up under the transmission action between the rack and the gear shaft, so that the limit block is separated from the limit groove on the arc plate, and the locking state of the rotary handle is released; when the rotary handle is released, under the action of the elastic force of the extrusion spring, the two groups of buttons will be reset to the initial state, and the limit block will slide into the limit groove at this time, completing the locking process after the switch is opened and closed, reducing the occurrence of the switch being accidentally opened and closed by external force.

[0004] However, the above-mentioned prior art has the following problems: although the above-mentioned switch structure can control the limit block to be inserted into or pulled out of the limit groove by setting a gear transmission structure to achieve the locking of the switch, when a button in the pressing structure on both sides of the handle of the switch structure is subjected to a certain collision, it will still drive the rack and the gear shaft to transmit, thereby causing the switch to be out of the locked state, so there is still a large degree of instability.
