The plug type high-voltage fuse protector changes the original one ceramic vase of the high-voltage fuse protector into two supporting ceramic vases, depends on the two supporting ceramic vases to bear the high-voltage fuse protector body; in this way, the high-voltage fuse protector is no longer fixed on one supporting ceramic vase through a bolt, but that the wiring end caps at the two ends are inserted in the clamping piece devices capable of being plugged at the upper ends of the two supporting ceramic vases; and the high-voltage fuse protector can be directly plugged when being mounted and replaced, and no bolt is needed to be screwed to waste a great quantity of time and labor, thereby realizing the quick treatment after the high-voltage fuse protector is fused.

Description

Easy-to-replace plug-in high-voltage fuses

technical field

The utility model belongs to the technical field of PT high-voltage insurance in substations, and in particular relates to a plug-in high-voltage fuse which is easy to replace.

Background technique

The PT high-voltage insurance of the substation plays an important role in protecting the safety of the PT and the entire substation system. In daily operation, it is often due to ferromagnetic resonance, single-phase indirect grounding and intermittent arc grounding in the system, and single-phase grounding or interphase grounding inside the PT. Short circuit fault, secondary circuit short circuit and secondary side fuse not blown, etc. cause PT high voltage fuse blown, usually high voltage fuse blown, if the fuse is not replaced in time, correctly and quickly, the protection, metering, etc. will lose voltage , resulting in immeasurable losses. After the fuse of the PT high-voltage fuse is blown, because the fuse is firmly fixed by four screws, when replacing it, it often takes too much time to tighten the four screws on the fuse, which makes it too long to replace the PT high-voltage fuse. Corrosion, the processing time will be longer. However, if the high-voltage fuse is blown, the secondary voltage of the corresponding busbar is disconnected, and the secondary voltage of another busbar needs to be used; if the processing time is too long, the reliability of power supply will be seriously affected.

Utility model content

The purpose of the utility model is to avoid the disadvantages of the above-mentioned prior art, and to provide a plug-in high-voltage plug-in high-voltage fuse that is time-saving and labor-saving, convenient and fast, ensures the reliability of power supply, and can realize rapid processing after the high-voltage fuse is blown. fuse.

The technical solution adopted to achieve the purpose of this utility model is: a plug-in type high-voltage fuse that is easy to replace, including a high-voltage fuse body and a supporting porcelain bottle, the two ends of the high-voltage fuse body are provided with terminal caps, and the support The upper end of the porcelain bottle is provided with a pluggable clamping device.

The pluggable clamping device includes an arc clamping device and an elastic sheet clamping device, and lead wires are arranged on the pluggable clamping device.

The clip clamping device includes two clips.

The beneficial effects of the utility model are: because the utility model changes the supporting porcelain bottle of the high-voltage fuse from the original one to two, relying on the two supporting porcelain bottles to carry the high-voltage fuse body across, so that the high-voltage fuse uses bolts instead of the original one. Instead of being fixed on a supporting porcelain bottle, the terminal caps at both ends are inserted into the pluggable clip devices on the upper ends of the two supporting porcelain bottles. After the high-voltage fuse body is inserted, it is set on the pluggable clip device. Clamped and fixed by the arc-shaped clamping device and the shrapnel clamping device. When installing the high-voltage fuse, there is no need to use bolts to fix it. Under the support of the two supporting porcelain bottles and the clamping action of the pluggable clamp device, the high-voltage fuse body is directly inserted into the two pluggable clamps. When the high-voltage fuse is disassembled after it is blown, you don’t need to loosen the screws, just pull up the high-voltage fuse body manually, which greatly shortens the time for disassembling the high-voltage fuse. In this way, when replacing the high-voltage fuse, there is no need It takes a lot of time and energy to tighten the bolts again. At the same time, the lead wire is fixed on the pluggable clip device, which also greatly shortens the maintenance time after the high-voltage fuse is blown. The utility model can realize rapid processing after the high-voltage fuse is blown, greatly reduces the processing time after the PT high-voltage fuse is blown, successfully reduces the processing time after the PT high-voltage fuse is blown from more than 80 minutes to about 40 minutes, and reduces construction costs. The risk of personnel replacing high-voltage insurance increases the reliability of power supply, saves time and effort, and is convenient and quick.

Description of drawings

Below in conjunction with accompanying drawing, the utility model will be further described:

Fig. 1 is a structural representation of the utility model,

Fig. 2 is a schematic structural view of the pluggable clip device in the utility model.

Detailed ways

As shown in Figure 1 and Figure 2: a plug-in high-voltage fuse that is easy to replace, including a high-voltage fuse body 1 and a supporting porcelain bottle 2, the two ends of the high-voltage fuse body 1 are provided with terminal caps 3, and the supporting The upper end of the porcelain bottle 2 is provided with a pluggable clip device 4 . The pluggable clamping device 4 includes an arc clamping device 5 and a shrapnel clamping device 6 , and a lead wire 7 is arranged on the pluggable clamping device 4 . The clip clamping device 6 includes two clips.

Utilize this utility model, change the support porcelain bottle of high-voltage fuse from the original one into two, rely on two support porcelain bottles 2 to carry the high-voltage fuse body 1 across, like this, high-voltage fuse is fixed on a support porcelain bottle by bolts Instead, the terminal caps 3 at both ends are inserted into two pluggable clip devices 4 supporting the upper ends of the porcelain bottles 2, and the high-voltage fuse body 1 is inserted and set on the pluggable clip devices. The arc clamping device 5 and the shrapnel clamping device 6 are clamped and fixed. When installing the high-voltage fuse, there is no need to use bolts to fix it. Under the support of the two supporting porcelain bottles 2 and the clamping action of the pluggable clamp device 4, the high-voltage fuse body 1 is directly inserted into the two pluggable Just pull out the clip device 4; when the high-voltage fuse is disassembled, you don’t need to loosen the screws, just pull up the high-voltage fuse body 1 manually, which greatly shortens the time for disassembling the high-voltage fuse.
