Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to a high-voltage switchgear fault isolation device. Background Technology

[0002] High-voltage switchgear fault isolation is a critical operation in power systems to ensure equipment safety and rapid power restoration.

[0003] In power systems, high-voltage switchgear is a critical power distribution device, and its fault isolation operation directly affects the safety of the power grid and the reliability of power supply. Currently, the standard procedure for handling high-voltage switchgear faults requires maintenance personnel to manually perform steps such as power disconnection and locking. Specifically, when a fault occurs, the circuit breaker and disconnecting switch must be disconnected first, followed by hanging a "Do Not Close, People Working" warning sign on the operating handle or cabinet door, and installing mechanical locks to isolate the fault area.

[0004] Maintenance personnel need to carry warning signs, locks and other auxiliary tools with them. In emergency repairs or complex environments, omissions or delays may occur, affecting the efficiency of fault isolation. Utility Model Content

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a high-voltage switchgear fault isolation device, the structure of which includes a cabinet door body, an LED light strip, an instrument panel, a high-reflectivity projection plate, a projection lamp bracket, a projection lamp, a battery box, a relay, and a manual switch. A rectangular groove is provided on the front side of the cabinet door body, and an LED light strip is provided in the rectangular groove. An instrument panel is provided on the cabinet door body, and a high-reflectivity projection plate is provided below the instrument panel. The top of the cabinet door body is fixedly connected to the projection lamp bracket, and a projection lamp is fixedly provided at the bottom of the projection lamp bracket. The projection lamp is connected to the battery box through a power line, and the power line is also connected to the relay. A switch that can be automatically triggered but can only be manually turned off is also provided on the power line.

[0007] Furthermore, the highly reflective projection panel is fixedly connected to the cabinet door body by adhesive bonding.

[0008] Furthermore, the projection lamp bracket has a structure that protrudes forward by 3-4 cm.

[0009] Furthermore, dry cell batteries are installed inside the battery box.

[0010] Furthermore, the relay is connected to the relay protection device inside the high-voltage cabinet, and the relay operates synchronously when the relay protection device operates.

[0011] Furthermore, a manual lock is also provided on the cabinet door body for manually locking the cabinet door during fault maintenance to prevent accidental opening.

[0012] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows: This high-voltage switchgear fault isolation device improves the situation where maintenance personnel need to carry warning signs, locks, and other auxiliary tools, which are prone to omissions or delays in emergency repairs or complex environments, affecting the efficiency of fault isolation. In this solution, the projection and light strip used for reminders and warnings will display the red words "Do not close the switch, people are working" when triggered, and the light strip will display a red running light effect, improving the warning effect. By connecting with the relay protection device in the high-voltage switchgear, the warning will be automatically activated when a fault occurs, eliminating the need for maintenance personnel to set up warning signs and other structures, thus improving the efficiency of fault isolation and maintenance.

[0016] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0017] refer to Figures 1-2 This embodiment provides a high-voltage switchgear fault isolation device, the structure of which includes a cabinet door body 1, an LED light strip 2, an instrument panel 3, a high-reflectivity projection plate 4, a projection lamp bracket 5, a projection lamp 6, a battery box 7, a relay 8, and a manual switch 9. A rectangular groove is provided on the front side of the cabinet door body 1, and the LED light strip 2 is arranged in the rectangular groove. The instrument panel 3 is arranged on the cabinet door body 1, and the high-reflectivity projection plate 4 is arranged below the instrument panel 3. The top of the cabinet door body 1 is fixedly connected to the projection lamp bracket 5, and the projection lamp 6 is fixedly arranged at the bottom of the projection lamp bracket 5. The projection lamp 6 is connected to the battery box 7 through a power line, and the power line is also connected to the relay 8. A switch that can be automatically triggered and can only be manually closed is also provided on the power line. The switch is an electromagnetic holding relay 8, which closes automatically when energized and needs to be manually pressed to unlock after power is cut off.

[0018] The highly reflective projection panel 4 is fixedly connected to the cabinet door body 1 by adhesive bonding.

[0019] The projection lamp bracket 5 has a structure that protrudes forward by 3-4cm; the projection lamp 6 has a built-in film with the red characters "Do Not Close" and uses a low-power LED light source with a projection distance of ≥2m;

[0020] Dry cell batteries are installed inside the battery box 7.

[0021] The relay 8 is connected to the relay protection device inside the high-voltage cabinet, and the relay 8 operates synchronously when the relay protection device operates.

[0022] The cabinet door body 1 is also equipped with a manual lock for manually locking the cabinet door during fault maintenance to prevent accidental opening.

[0023] This high-voltage switchgear fault isolation device improves upon the previous system where maintenance personnel had to carry warning signs, locks, and other auxiliary tools, which could easily be overlooked or delayed in emergency repairs or complex environments, affecting fault isolation efficiency. The projector and LED strip in this solution, used for reminders and warnings, display the words "Do Not Close, People Working" in red when triggered, and the LED strip also displays a red running light effect, enhancing the warning effect. By connecting to the relay protection device inside the high-voltage switchgear, the warning is automatically activated in case of a fault, eliminating the need for maintenance personnel to set up warning signs or other structures, thus improving fault isolation and maintenance efficiency.
