Abstract
The utility model discloses a lightning -protection distribution box, including casing and block terminal, the block terminal is established in the casing, block terminal side outer surface of the wall is equipped with the earth connection passageway, and this earth connection passageway comprises the frid of fixing at the block terminal lateral wall, is equipped with ground lead in this earth connection passageway, and the dress connect the current -limiting lightning rod after the casing was passed to this ground lead upper end, and ground lead lower extreme dress ground connection copper line still is equipped with the lightning current and blocks the device in the block terminal, and the built -in thunder and lightning inhibitor that is equipped with the propagation passageway of blocking the lightning current of device, this thunder and lightning inhibitor and ground connection copper line connection are blocked to the lightning current. The utility model discloses lightning proof effect is good, simple to operate.
Description
Technical field
The utility model relates to technical field of electric equipment, specifically a kind of lightning-protection distribution box.
Background technology
Along with the progress of science and technology, the automation system being made up of minicomputer and large-scale integrated circuit device, replaces conventional measurement and monitors the relaying of instrument, conventional control panel, central signal system, dynamic screen far away and routine. Improve automatization and intelligent level.
But; produced problem is thereupon; for the unicircuit of microsystem; only the three ten-day period of hot season, signalling current are only microampere order to running voltage; shock-resistant capacity is possessed little than conventional electromagnetic type protector; the tolerance of surge is more fragile, and particularly the transient state impact of Lightning Over-voltage can cause microsystem badly damaged, and therefore the anti-lightning strike problem of the integrated automation such as microsystem, computer network at present, intelligent equipment is required to incorporate in normal protection.
Summary of the invention
The technical problems to be solved in the utility model is to provide the good lightning-protection distribution box of a kind of lightning protection effect.
In order to solve the problems of the technologies described above, the utility model takes following technical scheme:
A kind of lightning-protection distribution box, comprise housing and switch box, switch box is located in housing, described switch box sidewall outside surface is provided with grounding wire passage, this grounding wire passage is made up of the frid being fixed on switch box sidewall, it is provided with ground lead in this grounding wire passage, this ground lead upper end is through attaching current-limited arrester after housing, the lower end attaching of ground lead has ground connection copper cash, lightning current occluding device also it is provided with in switch box, the thunder and righting blanker being equiped with the propagation ducts blocking lightning current in lightning current occluding device, this thunder and righting blanker is connected with ground connection copper cash.
Described current-limited arrester is made up of metal tip and the pedestal be made up of conductive polymer silastic material, and metal tip is inserted in this pedestal, and ground lead interts in this pedestal and is fixedly connected with.
It is filled with fire retardant material in grounding wire passage on described switch box sidewall.
The sidewall of described grounding wire passage is provided with window, and this window is provided with cover plate in hinged way.
Described cover plate is provided with handle ring.
The Surface coating of described ground lead has insulation layer.
The utility model lightning protection effect is good, it is possible to conveniently install ground lead, is convenient to follow-up maintenance and checks at any time.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model cross-sectional view.
Embodiment
For the ease of the understanding of those skilled in the art, below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1, the utility model discloses a kind of lightning-protection distribution box, comprise housing 1 and switch box 2, switch box 2 is located in housing 1, described switch box 2 sidewall outside surface is provided with grounding wire passage 5, this grounding wire passage 5 is made up of the frid being fixed on switch box 2 sidewall, it is provided with ground lead 8 in this grounding wire passage 5, this ground lead 8 upper end is through the rear attaching current-limited arrester 3 of housing 1, ground lead 8 times end attachings have ground connection copper cash, lightning current occluding device 9 also it is provided with in switch box 2, the thunder and righting blanker of the propagation ducts blocking lightning current it is equiped with in lightning current occluding device, this thunder and righting blanker is connected with ground connection copper cash. current-limited arrester 3 is made up of metal tip 31 and the pedestal 32 be made up of conductive polymer silastic material, and metal tip is inserted in this pedestal, and ground lead interts in this pedestal and is fixedly connected with. the Surface coating of ground lead has insulation layer. for lightning current occluding device and thunder and righting blanker, all adopt existing known products, its concrete structure be there is no specific requirement.
In addition, it is filled with fire retardant material in the grounding wire passage 5 on switch box 2 sidewall, by arranging fire retardant material, it is possible to effectively avoid the fire that electric current causes. The sidewall of grounding wire passage 5 is provided with window, and this window is provided with cover plate 6 in hinged way. Cover plate 6 is provided with handle ring 7, and by the opening and closing cover plate that this handle ring can be convenient, thus the ground lead in earth wire passage carries out checking and follow-up maintenance.
It should be noted that, the above is not to the restriction wanting new technique scheme, is not departing under the prerequisite creating design of the present utility model, and any apparent replacement is all within protection domain of the present utility model.
