Description

Technical Field

[0001] This utility model relates to the technical field of interlocking tripping devices, specifically an interlocking tripping device for power switchgear. Background Technology

[0002] An interlocking tripping device in a power switchgear is a safety protection device used in power systems. It is primarily used to automatically disconnect the power supply to protect equipment and personnel when a fault or abnormality occurs. Its core function is to ensure, through an interlocking mechanism, that the circuit can be quickly and reliably disconnected under specific conditions (such as misoperation or equipment failure).

[0003] A power switchgear interlocking tripping device is disclosed in Chinese utility model patent application publication CN216489177U. Although it can sense the automatic tripping of the control switch through the identification module and complete the interlocking tripping of the power meters in each power unit in the switchgear through the push rod mechanism, this safety protection device for power systems has the disadvantage that it is impossible to quickly find the fault and repair it after pushing all the switches. At the same time, because a large number of switches need to be pushed, there may be situations such as the switches not being able to be pushed or getting stuck. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1

[0025] Please see Figures 1 to 6This utility model provides a technical solution: an interlocking tripping device for a power switchgear, comprising a power switchgear 1, with an interlocking tripping device fixedly connected inside the power switchgear 1. The interlocking tripping device includes a second knife block seat 8, a first main knife block seat 9, a main knife block 10, a push plate 11, a triangular push plate 12, a telescopic rod 13, a fixing plate 14, and a second main knife block seat 15. The second knife block seat 8 is fixedly connected inside the power switchgear 1, located above the first knife block seat 5, and a second main knife block seat 15 is provided on one side of the second knife block seat 8. The first main knife block seat 9 is provided below the second main knife block seat 15, and a main knife block 10 is movably connected inside the first main knife block seat 9. A push plate 11 is fixedly connected to one end of the main knife block 10, and one end of the push plate 11 is triangular. A fixing plate 14 is fixedly connected inside the power switchgear 1, fixedly connected to the right side of the first main knife block seat 9, and a telescopic rod 13 is fixedly connected to the left side of the fixing plate 14. One end of the telescopic rod 13 is movably connected to a triangular push plate 12, which contacts the push plate 11. This power switchgear interlocking tripping device, through the setting of the first main switch seat 9, enables the power switchgear interlocking tripping device to achieve the overall control of each area controlled by each first switch seat 5 through the first main switch seat 9. Through the cooperation of the reflector 7 and the light sensor 16, during use, the signal reflected by the reflector 7 and the light sensor 16 can control the telescopic rod 13 to push the triangular push plate 12, causing the first main switch seat 9 to trip. Thus, when there is an abnormal trip of the first switch seat 5, the signal reflected by the reflector 7 and the light sensor 16 can push the first main switch seat 9 to trip, thereby achieving the interlocking tripping function of controlling the overall tripping by the local tripping in the area. It achieves the purpose of controlling the overall tripping in the area with a single tripping, with a simple structure and strong practicality.

[0026] In use, the telescopic rod 13 is first retracted to close all the switches. During operation, if a trip occurs in the area due to operational errors or other reasons, the tripping switch 6 will spring back. The reflector 7 at one end of the tripping switch 6 can reflect the signal at the light sensor 16, thereby triggering the light sensor 16. The triggering of the light sensor 16 can transmit the signal to the telescopic rod 13, which will extend and push the push plate 11 through the triangular push plate 12, causing the first main switch seat 9 in a single area to trip, thereby controlling the interlocking trip of the entire area.

[0027] Example 2

[0028] Please see Figures 1 to 6This utility model provides a technical solution: a power switchgear interlocking tripping device, including a power switchgear 1. A partition 19 is fixedly connected inside the power switchgear 1. Several observation windows 17 are provided on the front of the power switchgear 1, and these windows are evenly distributed in a linear array between the two partitions 19. A warning device is fixedly connected to the outer surface of the power switchgear 1. The warning device includes a buzzer alarm 2, a warning light 3, a first knife switch seat 5, a tripping knife switch 6, a reflector 7, a light sensor 16, and gaskets 18. A warning light 3 is fixedly connected to the front of the power switchgear 1. A buzzer alarm 2 is fixedly connected to the top of the power switchgear 1. Several gaskets 18 are fixedly connected inside the power switchgear 1, and these gaskets rise sequentially from left to right. A first knife switch seat 5 is fixedly connected to the front of the gasket 18. A tripping knife switch 6 is movably connected inside the first knife switch seat 5. Several warning lights 3 are provided. The circuit breakers are evenly distributed in a linear array on the front of the power switch cabinet 1, corresponding to each branch switch 6. A reflector 7 is fixedly connected to one end of each branch switch 6. A light sensor 16 is fixedly connected to the inner side surface of the power switch cabinet 1. An electronic component 4 is fixedly connected inside the power switch cabinet 1, located above the corresponding switch holder. The first switch holder 5 and the second switch holder 8 are located above the partition 19. This power switch cabinet interlocking tripping device, through the setting of the buzzer alarm 2, enables the power switch cabinet interlocking tripping device to transmit the signal to the buzzer alarm 2 after the light sensor 16 receives the signal, so as to achieve the warning effect. Through the setting of the warning light 3, after the switch trips during use, the reflected signal can be transmitted to each corresponding warning light 3, thereby facilitating maintenance personnel to quickly find the tripped switch and achieve rapid inspection of the tripped area, thereby improving the maintenance efficiency of maintenance personnel.

[0029] When a single circuit breaker 6 in a certain area trips, the signal from the light sensor 16 can be reflected by the reflector 7 at one end of the circuit breaker 6. After receiving the signal, the light sensor 16 can transmit the signal to the buzzer alarm 2, thereby achieving the warning effect. At the same time, the reflected signal can be transmitted to the corresponding warning light 3, making it easier and faster for maintenance personnel to find the tripped area. After the maintenance is completed, the telescopic rod 13 is retracted, and the circuit breaker 6 and the main circuit breaker 10 are returned to their original positions.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
