Problems solved by technology

[0002] The functions of the existing lightning protection equipment are maturing day by day, and the effect and field of lightning protection are also constantly expanding. However, since the device belongs to the electrical field after all, the parts used have a certain life span. The service life is about 15 years, and the products in the field of lightning protection are about 10-15 years. Lightning protection is no small matter. If a product is used for too long, its performance will be greatly reduced due to the aging of the product, and the lightning protection effect and ability will also be reduced. If the product that has lost the lightning protection capability is still used for lightning protection, it will be a great harm to the human body.

Embodiment 1

[0015] Embodiment 1: in combination with figure 1 , 2 , 4 description.

[0016] A mechanical self-destruct surge protector, comprising a housing 4 and a power input port 1 and a power output port 2 made on it, the housing 4 is built with a self-destruct switch assembly (3); The destroy switch assembly 3 includes a fixed-speed motor 6 connected to the power supply input terminal with a gear one 5; the gear one 5 meshes with a gear two 7; the gear two 7 meshes with a gear three 8; the gear three 8 is coaxial with a gear Four 9, gear four 9 are meshed with gear five 10 in the horizontal direction, and the upper end of the circumference of the gear five 10 has a moving electrode 11, and the moving electrode 11 is in contact with the lower surface of the static electrode 12; the upper surface of the static electrode 12 is in contact with the power output port 2; The moving electrode 11 and the static electrode 12 are connected in series on the output circuit of the surge protect...

Embodiment 2

[0018] Embodiment 2: in combination with figure 1 , 2 , 3 description

[0019] The transmission ratio of the first belt gear 5 and the second gear 7 is 1:30-31; the transmission ratio of the second gear 7 and the third gear 8 is 1:12; the transmission ratio of the fourth gear 9 and the fifth gear 10 is 1:20.

[0020] The static electrode 12 is called a semicircle. The self-destruct switch is composed of a moving electrode 11 and a static electrode 12 connected in series; the switch is a one-time switch.

[0021] For example, if the surge protector is designed for ten years, the transmission ratio of gear 4 9 and gear 5 10 is 1:20, and so on. When gear 4 rotates 10 times, gear 5 drives the moving electrode 11 on the static electrode. Large semi-circular movement separates the moving and static electrodes, and cuts off the output power without reset.

Abstract

The invention belongs to the technical field of lightning protection, and provides a mechanical self-destruction surge protection device. The surge protection device mainly comprises a self-destruction switch assembly, wherein the self-destruction switch assembly comprises a constant speed motor which is connected with a power supply input end and provided with a first gear; the first gear is engaged with a second gear; the second gear is engaged with a third gear; a fourth gear is coaxially arranged on the third gear, and horizontally engaged with a fifth gear; a moving electrode is arranged at the upper end of the circumference of the fifth gear, and contacted with the lower surface of a static electrode; the upper surface of the static electrode is contacted with a power supply output port; and a preferable transmission ratio structure can achieve a function of cutting off an output power supply when an age limit is reached, so that the power supply can only be input but not be output, and the surge protection device is forcefully scrapped. The surge protection device is simple in structure and high in cost performance, and well prevents waste and out-of-date products from being put into operation.

Description

technical field [0001] The invention belongs to the technical field of lightning protection, and in particular relates to a mechanical self-destruction surge protector. Background technique [0002] The functions of the existing lightning protection equipment are maturing day by day, and the effect and field of lightning protection are also constantly expanding. However, since the device belongs to the electrical field after all, the parts used have a certain life span. The service life is about 15 years, and the products in the field of lightning protection are about 10-15 years. Lightning protection is no small matter. If a product is used for too long, its performance will be greatly reduced due to the aging of the product, and the lightning protection effect and ability will also be reduced. If the product that has lost the lightning protection capability is still used for lightning protection, it will be a great harm to the human body. Contents of the invention [00...
