Embodiment 1

[0017] Such as figure 1 As shown, the present invention improves the structure of the JSY-8 discharge counter, including a housing 1, a glass cover 2, a valve plate, a silicon bridge rectifier, a capacitor, an electromagnetic counter and a display screen, and the glass cover is set as a convex spherical surface type glass cover, the display screen is a page-turning digital display screen, and the outer surface of the display screen number 3 is covered with a fluorescent layer; a sealing rubber pad is set inside the housing; With sealing ring.

[0018] The housing is set as a cuboid with a length of 250 mm and a width of 200 mm. The height of the digital font on the display screen is 150 mm. The conversion of the numbers adopts a mechanical jump mode in which gears drive the display screen.

[0019] The working temperature of the present invention is -40°C to 50°C, and the action accuracy is 100%.

Embodiment 2

[0021] Such as figure 2 As shown, it includes a housing 1, a glass cover 2, a valve plate, a silicon bridge rectifier, a capacitor, an electromagnetic counter and a display screen. The glass cover is set as a convex spherical glass cover. The surface is covered with a fluorescent layer; a sealing rubber pad is arranged inside the casing; a high-voltage outlet hole is arranged on the bottom plate of the casing, and a sealing ring is arranged between the high-voltage outlet hole and the high-voltage outlet.

[0022] The housing is configured as a cuboid with a length of 250 mm and a width of 200 mm.

[0023] The working temperature of the present invention is -40°C to 50°C, and the action accuracy is 100%.

[0024] The working principle of the present invention is that, through the continuous flow of the energy impact current of the lightning arrester, the pressure is taken on the valve plate, and the capacitor is unidirectionally charged through the silicon bridge rectifier, ...

Abstract

The invention relates to a discharge counter for a line lightning arrester. The discharge counter for the line lightning arrester comprises a shell, a glass sealing cover, a valve block, a silicon bridge rectifier, a capacitor, an electromagnetic counter and a display screen. The glass sealing cover is a convex sphere type glass sealing cover, and the outer surface of numbers of the display screen are covered with a fluorescent layer. The discharge counter for the line lightning arrester can adapt to the height of a transmission tower, and full-screen large-size numbers can be displayed in a page turning mode; meanwhile, the numbers are coated with fluorescent powder, so requirements for night observation are met. Convex sphere glass is adopted in the glass sealing cover of the counter, and the digital display effect can be further enhanced.

Description

technical field [0001] The invention relates to a power system counter, in particular to a discharge counter for a line lightning arrester, which belongs to the technical field of intelligent substations. Background technique [0002] In the prior art, the counters used for line arresters are all placed on very high towers, generally about 70 meters, because the placement position is too high, and the number displayed by the counter is too small, so it is difficult to check the operation situation, especially at night. More unrecognizable. Contents of the invention [0003] The present invention aims at the problems existing in the above-mentioned prior art, improves the structure on the basis of the existing arrester counter, and provides a discharge counter for line arrester, which solves the inconvenience of checking the counter in the prior art . [0004] Technical scheme of the present invention is as follows: [0005] It includes a shell, a glass cover, a valve ...
