[0015] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] Embodiment 1

[0017] See attached Figure 1-2 The utility model proposes a gap arc blowing device, including an insulator 10, with a first conductive plate 12 and a second conductive plate 13 (both the first conductive plate 12 and the second conductive plate 13 are made of alloy aluminum material) installed on both sides of the insulator 10; wherein, the first conductive plate 12 is installed at the top position of the side wall of the insulator 10, and the second conductive plate 13 is installed on the bottom wall of the insulator 10; when lightning enters the device, the lightning falls on the first conductive plate 12, and then passes through the discharge electrode a14 and the discharge electrode b15 to the second conductive plate 13, and finally enters the lightning arrester 20.

[0018] A discharge electrode a14 is installed on the first conductive plate 12, and a discharge electrode b15 is installed on the second conductive plate 13. A discharge channel is formed between the discharge electrode a14 and the discharge electrode b15 to guide the lightning current to pass through.

[0019] Air holes 16 are provided on the opposite side walls of the discharge electrodes a14 and b15; when the lightning current passes through the discharge electrodes, the air holes 16 can generate airflow or arc blowing effect, which helps to extinguish or weaken the arc and reduce the damage of lightning to the equipment.

[0020] The distance between the discharge electrode a14 and the discharge electrode b15 is between 40 mm and 50 mm.

[0021] An installation mechanism is provided on the insulator 10, and the installation mechanism is used to install the insulator 10 on the lightning arrester 20. The installation mechanism includes a installation hole 11 opened inside the insulator 10, and a mounting screw 21 is installed on the top wall of the lightning arrester 20. The mounting screw 21 is movably inserted from the inside of the mounting hole 11, and a nut is installed at the top position of the insulator 10; wherein, when the insulator 10 is installed on the lightning arrester 20, the mounting screw 21 on the lightning arrester 20 can be inserted from the mounting hole 11, and then locked on the mounting screw 21 with a nut at the top of the insulator 10, thereby completing the installation of the insulator 10 and the lightning arrester 20. In addition, an insulating box is also fixedly installed on the top wall of the insulator 10, and the nut is located inside the insulating box to prevent lightning from directly entering the lightning arrester 20 through the nut and the mounting screw 21.

[0022] In this embodiment, by combining the gap discharge effect of the discharge electrode and the arc blowing effect, the lightning current is effectively guided and extinguished, thereby improving the protection effect of the arrester, the line and the transformer.

[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
