Example Embodiment

[0016] See figure 1 with figure 2 As shown, the core column 2 of the present invention is arranged in the composite jacket 3, the composite jacket 3 is provided with a supporting column 17, the upper and lower ends of the composite jacket 3 are provided with a high pressure end 1 and a low pressure end 4, and the core column 2 is set on the base 6, the supporting column 17 includes thirteen special zinc oxide resistors 13 stacked in series. The resistor strip 13 is in a high-resistance state under normal operating voltage, which is equivalent to an open circuit; under an overvoltage, it is in a low-resistance state, which is equivalent to a short circuit. In an overvoltage environment, the resistor strip 13 is turned on instantly to release electric energy, and after the overvoltage disappears, it can automatically restore the high resistance state. The resistor strips 13 at the upper and lower ends each correspond to an end pad 12, which is made of aluminum alloy with high s...

Abstract

The invention relates to a lightning arrester device, which is provided with a support column, and the support column includes resistance sheets stacked together in series, two support column fixing mechanisms and two end pads, the resistance sheets form a resistance sheet column, The resistance piece column is placed vertically, the resistance piece column is arranged between the two support column fixing mechanisms, the end surface of the end pad is attached to the end surface of the resistance piece, and the side surface of the end pad is provided with a convex Edge, the outer surface of the resistor sheet column is provided with a vertically placed heat shrinkable tube. The invention has a reasonable structure, and the structure encapsulates the resistance piece into a resistance piece column through the heat-shrinkable tube and the end pad, which not only enhances the insulation performance of the core column, better protects the resistance piece, but also makes the assembly process of the core column Simultaneously, it plays a role of isolation and protection for the resistance sheet, which is beneficial to delay the aging of the resistance sheet. The invention has strong stability and improves working efficiency.

Description

technical field [0001] The invention belongs to the field of manufacturing technology, and in particular relates to a lightning arrester device. Background technique [0002] The function of the arrester is to limit the overvoltage to protect the electrical equipment. The non-gap zinc oxide mine was used in the early production in our country. The operation practice shows that it has the disadvantages of high damage and explosion rate and short service life. The reason is that the poor ability to withstand transient overvoltage is its Achilles heel. The series gap zinc oxide arrester still has the protection performance advantages of the gapless zinc oxide arrester, and at the same time has the characteristics of strong transient overvoltage withstand capability, which is an ideal product that maximizes strengths and avoids weaknesses. At present, the lightning arresters for railway high-speed EMUs need to be imported and have not been domestically produced. There are stil...
