Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage live displays, in particular to a high-voltage live display with new functions. Background Art

[0002] High-voltage live-voltage display devices are typically installed on incoming busbars, circuit breakers, main transformers, switchgear, GIS combination electrical appliances, and other locations where it's necessary to indicate whether a device is live to prevent electrical misoperation. The display has a self-test function that simulates high-voltage input, allowing for constant verification of the display's functionality. It also includes a test hole for external electrical testing and phase verification. For example, Chinese patent application number CN202221864551.9, which describes a high-voltage live-voltage display with a phase verification test hole, shows that the fixings are mounted on the bottom shell to secure the outer shell to the door of the high-voltage switchgear. There are two fixings, symmetrically mounted on either side of the bottom shell.

[0003] However, since the high-voltage live display is generally fixed to the door panel of the electric control cabinet by screws and threaded connections on fixing parts, it is inconvenient to install, replace and disassemble the high-voltage live display. Utility Model Content

[0004] In order to solve the problem raised in the above background technology that the high-voltage live display is generally fixed on the door panel of the electric control cabinet by screws and threaded connections on the fixing parts, thereby making it inconvenient to install, replace and disassemble the high-voltage live display, the utility model provides the following technical solutions:

[0005] A high-voltage live display with new functions includes a display panel. A bottom shell for supporting the display panel is fixedly installed at the rear end of the display panel. A clamping device for fixing the bottom shell is provided in the bottom shell, and there are four clamping devices.

[0006] The clamping device includes an arched spring piece for clamping the bottom shell, and a driving component for driving the arched spring piece to clamp the bottom shell is arranged in the bottom shell.

[0007] Furthermore, the upper and lower ends of the bottom shell are provided with storage grooves for storing the clamping device, and there are two storage grooves, which are symmetrically distributed at the upper and lower ends of the bottom shell, so that the driving component can be used to control the arched spring sheet to be stored in the storage groove, so that the clamping between the bottom shell and the high-voltage switch cabinet can be released, so that the high-voltage live display can be quickly removed.

[0008] Furthermore, fixing plates for guiding the bottom shell are fixedly installed at the left and right ends of the bottom shell.

[0009] Furthermore, the driving assembly includes a threaded rod arranged in the receiving groove for driving the arched spring sheet to be received, and a handwheel for driving the threaded rod to rotate is fixedly mounted on the front end of the threaded rod.

[0010] Furthermore, a live indicator light is provided on the front side of the display panel for indicating the display panel, and there are three live indicator lights, which are distributed in a linear array on the front side of the display panel. When the high-voltage equipment is energized, the live indicator light will emit red light, reminding the staff in an intuitive and eye-catching manner that the current equipment is carrying high voltage electricity, so as to prevent the staff from accidentally entering the high-voltage live interval or operating the live grounding knife switch, which may cause personal safety and equipment failure.

[0011] Furthermore, the front side of the display panel is provided with a phase test hole for performing a phase test, and there are three phase test holes. The three phase test holes are distributed in a linear array on the front side of the display panel. A button is provided on the front side of the display panel. Since the high-voltage switchgear needs to undergo a high-voltage phase test before being put into operation, the phase test can be completed by connecting the probe of the phase instrument to the corresponding phase test hole, thereby achieving the purpose of safety, convenience and speed.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] By providing a receiving groove and a clamping device, when the display panel needs to be removed from the high-voltage switch cabinet, the threaded rod can be rotated by the handwheel, so that the arched spring piece can be moved along the rod body of the threaded rod, and the arched spring piece can be stored in the receiving groove, so that the arched spring piece and the high-voltage switch cabinet can be locked, and the display panel can be quickly replaced and disassembled.
