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
The present invention relates to a kind of electric system counter, relate in particular to a kind of leakage conductor discharge counter, belong to intelligent substation technical field.
Background technology
In prior art, the counter that leakage conductor is used all will be placed on very high shaft tower, general 70 meters of left and right, and because riding position is too high, and counter shows that numeral is too little, thus be difficult to check action situation, especially night, more cannot identification.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, on the basis of existing counter for lightning arrester, structure is improved, a kind of leakage conductor discharge counter is provided, solved and in prior art, checked that counter exists inconvenient problem.
Technical scheme of the present invention is as follows:
Comprise housing, glass capping, valve block, silicon dridge type rectifier, capacitor, message register and display screen, glass capping is set to evagination sphere formula glass capping, and the outside surface of display screen numeral covers fluorescence coating.
Described display screen is pivoted digital display screen.
Sealed rubber pad is set in described housing.
On described housing base plate, high-voltage terminal hole is set, between high-voltage terminal hole and high-voltage terminal, is provided with O-ring seal.
Described housing is set to rectangular parallelepiped.
Advantageous effect of the present invention is as follows:
Highly sensitive, record accurately and reliably, clear display is obvious, structure is light and handy, good looking appearance, easy to install, sealing reliably, long service life; Adapt to transmission tower height, housing is arranged to rectangular structure, and the pivoted demonstration of large size numeral all over the screen, covers fluorescence coating in number, has met the needs of night observation.Counter glass capping is used evagination spherical glass instead further to increase digital display effect.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is embodiment of the present invention structural representation.
In figure, 1, housing, 2, glass capping, 3, display screen numeral, 4, pointer.
Embodiment
Referring to accompanying drawing, in conjunction with specific embodiments, describe structure of the present invention in detail.
As shown in Figure 1, the present invention improves the structure of JSY-8 discharge counter, comprise housing 1, glass capping 2, valve block, silicon dridge type rectifier, capacitor, message register and display screen, glass capping is set to evagination sphere formula glass capping, display screen is pivoted digital display screen, and the outside surface of display screen numeral 3 covers fluorescence coating; Sealed rubber pad is set in housing; High-voltage terminal hole is set on housing base plate, between high-voltage terminal hole and high-voltage terminal, is provided with O-ring seal.
Described housing is set to rectangular parallelepiped, long 250mm, and wide 200mm, display screen digital font height 150mm, the conversion of numeral adopts the mechanical redirect mode of gear driven display screen.
Working temperature-40 of the present invention DEG C are to 50 DEG C, action accuracy 100%.
As shown in Figure 2, comprise housing 1, glass capping 2, valve block, silicon dridge type rectifier, capacitor, message register and display screen, glass capping is set to evagination sphere formula glass capping, and the outside surface of display screen numeral 3 and pointer covers fluorescence coating; Sealed rubber pad is set in housing; High-voltage terminal hole is set on housing base plate, between high-voltage terminal hole and high-voltage terminal, is provided with O-ring seal.
Described housing is set to rectangular parallelepiped, long 250mm, wide 200mm.
Working temperature-40 of the present invention DEG C are to 50 DEG C, action accuracy 100%.
Principle of work of the present invention is, the afterflow of the energy impact electric current by lightning arrester, pressure on valve block, through silicon dridge type rectifier, unidirectional to capacitor charging, and with direct current, message register coil discharge is made counter suction moving once, record once, is realized the number of times of operation of recording.
The present invention, in the insulated overhead conductor lightning protection science and technology item of 10kV main line shaft tower, tests in the microwave tower lightning protection science and technology item of 10 kilovolts of shaft towers, and it is convenient to check, observes clear, is worthy of popularization.
