Description

Technical Field

[0001] The utility model relates to a knife switch position auxiliary judgment device. Background Art

[0002] At present, the GIS equipment on the market is a closed structure. Users cannot judge from the outside whether the internal knife switch is open or closed. If the knife switch is not open or closed properly, it is easy to cause a safety accident. In order to solve this problem, some knife switch opening and closing position monitoring systems have emerged at this stage. The monitoring system monitors and feedbacks the knife switch position, but these monitoring systems usually report to the main control, and the on-site personnel need to obtain information through the control center. It takes time to obtain information, so there are problems of poor intuitiveness and low efficiency.

[0003] Therefore, it is necessary to make further improvements. Utility Model Content

The knife switch inside the GIS device has a rotating shaft leading out of the GIS device, one end of the lever is fixed on the rotating shaft and rotates therewith, and the judgment module includes a base, a micro switch, a light source and a power supply. The base is fixed to the outside of the GIS device, the power supply is arranged inside the base and provides working power for the light source, the micro switch and the light source are arranged outside the base, and the trigger part of the micro switch is located on the rotation path of the lever. The micro switch is used to control the on and off of the power supply line of the light source. When the trigger part is triggered by the lever, the micro switch connects the power supply line of the light source.

[0006] In one or more embodiments, a power monitoring module and a buzzer are provided on the base, the power monitoring module is used to monitor the power value of the power supply, and when the power value of the power supply is lower than a preset value, the buzzer works.

[0007] In one or more embodiments, the light source is an LED light board, and the LED light board and the micro switch are fixed to the base by screws.

[0008] In one or more embodiments, the power source is a lithium battery, a battery compartment for installing the lithium battery is provided inside the base, and a battery cover that can open the battery compartment is provided on the side wall of the base.

[0009] In one or more embodiments, two or more connecting steps are provided at the bottom of the base, and holes for installation and fixing are provided on the connecting steps.

[0010] In one or more embodiments, the lever is fixed to the rotating shaft by screws.

[0011] Compared with the background technology, the utility model has the following effects: the auxiliary judgment device can provide visual switch position judgment for on-site personnel without information feedback from the control center, and the auxiliary judgment device has low cost and strong practicality.

[0013] Figure 2 It is a schematic diagram of each electrical unit of the auxiliary judgment device according to an embodiment of the utility model. DETAILED DESCRIPTION

[0014] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0015] Please see attached Figure 1-2 The present application provides a device for auxiliary determination of knife switch position, which includes a GIS device 1, a lever 2 and a determination module. The knife switch inside the GIS device has a rotating shaft 3 leading out of the GIS device. One end of the lever 2 is fixed on the rotating shaft and rotates with it. The determination module includes a base 4, a micro switch 5, a light source 6 and a power supply 7. The base is fixed to the outside of the GIS device, the power supply is arranged inside the base and provides power for the light source to work. The micro switch 5 and the light source 6 are arranged outside the base, and the triggering part of the micro switch 5 is located on the rotation path of the lever 2. The micro switch 5 is used to control the on and off of the power supply line of the light source. When the triggering part is triggered by the lever, the micro switch connects the power supply line of the light source. Specifically, when the knife switch is in the closed state, the lever rotates to trigger the micro switch, and the light source is illuminated. At this time, an outsider can judge that the knife switch is in the closed state by the illumination of the light source; otherwise, the knife switch is in the open state.

[0016] The base 4 is provided with a power monitoring module 8 and a buzzer 9. The power monitoring module is used to monitor the power value of the power supply 7, and when the power value of the power supply is lower than a preset value, the buzzer works. The power monitoring module can avoid the light source from failing to work properly due to insufficient power supply, and the buzzing sound of the buzzer can serve as a prompt for insufficient power.

[0017] The light source 6 is an LED light board, and the LED light board and the micro switch are fixed to the base 4 by screws, so that when the micro switch or the light source is damaged, it can be quickly replaced.

[0018] The power source 7 is a lithium battery. A battery compartment for installing the lithium battery is provided inside the base. A battery cover that can open the battery compartment is provided on the side wall of the base. By opening the battery cover, the old battery can be removed and replaced with a new battery.

[0019] The bottom of the base 4 is provided with two or more connecting steps, and the connecting steps are provided with holes 10 for installation and fixing. After the holes are connected by screws, they are connected and fixed with screw holes reserved on the GIS equipment.

[0020] The lever 2 is fixed to the rotating shaft 3 by screws. The lever is installed by screws, which has the advantage of being easy to install and disassemble.

[0021] The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the contents disclosed in the present invention should be included in the protection scope recorded in the claims.
