The utility model is achieved in that
A kind of lightning protection for power supply, can comprise lightning protection components and parts, conductive braided fabric copper strips, electrode slice, dropout sliding display panel, remote signalling interlock dwang, metal dropout safety plate, described metal dropout safety plate can be fixed on the dropout sliding display panel, the metal dropout safety plate other end can be connected an electrode slice of lightning protection device by the conductive braided fabric copper strips, its side exit can be connected with an end brace of lightning protection components and parts, and the other end brace of lightning protection components and parts can connect another electrode slice of lightning protection device by the conductive braided fabric copper strips; Described lightning protection for power supply can comprise that also one is connected with the rotation post of remote signalling interlock dwang.
The afterbody sliding display panel projection glue position of being threaded off in described remote signalling interlock dwang upper end is blocked, and remote signalling interlock dwang lower end can place lost efficacy action mouthful and withstand the base remote signalling button of lightning protection device of end box shell remote signalling.Can make the loop of the long-range remote signalling interface of base be in set a kind of closed off-state.
Described dropout sliding display panel is arranged in the frame of end box shell movably.
Described metal dropout safety plate side exit connects the lightning protection components and parts brace that can be connected to the joint welding of low temperature tin.
But described metal dropout safety plate side exit joint welding is in the upper end of lightning protection components and parts brace.
Described metal dropout safety plate can be fixed on the dropout sliding display panel by screw.
The utility model project organization connecting line is short out, on properties of product, make the lightning protection device deboost lower, and this structure maximum using the space of end box shell, insulation distance between the lightning protection component opposed polarity is designed into the size that the flashover phenomenon does not take place when satisfying large lightning current and high voltage, makes the product through-flow performance of being struck by lightning more superior.Metal is threaded off the safety plate joint welding on lightning protection components and parts brace, need on the lightning protection device structure to have guaranteed the parts of motion can not be subjected to the interference and the obstruction of any external force, thereby guaranteed that product dropout action can smooth and easy finishing.Overall construction design is more convenient for assembling operation, is more conducive to guarantee product quality.

Embodiment
Below in conjunction with reference to the accompanying drawings and specific embodiment come the utility model is described in detail.
The utility model lightning protection for power supply comprises upper cover plate, end box shell 1, lightning protection components and parts 2, two conductive braided fabric copper strips 8, two electrode slices 3, dropout sliding display panel 4, remote signalling interlock dwang 5, rotation post 13, metal dropout safety plate 7 and thrust springs 6.1 design of end box shell is two frames of size up and down, and in the big frame, dropout sliding display panel 4 was arranged in the little frame 10 in top versatilely below lightning protection components and parts 2 were arranged on; Two screws 9 of metal dropout safety plate 7 usefulness are fixed on the dropout sliding display panel 4, metal dropout safety plate 7 other ends are connected on the electrode slice 3 of lightning protection device by conductive braided fabric copper strips 8, the side exit is connected with an end brace 11 usefulness low temperature tin joint welding of lightning protection components and parts 2, and the other end brace 11 of lightning protection components and parts 2 is connected another electrode slice 3 of lightning protection device by conductive braided fabric copper strips 8; Remote signalling interlock dwang 5 is loaded on rotation post 13, the remote signalling interlock dwang 5 upper end afterbodys sliding display panel 4 projection glue positions of being threaded off are blocked during the lightning protection device normal condition, remote signalling interlock dwang 5 lower ends just place end box shell 1 remote signalling inefficacy action mouth, and withstand the base remote signalling button of lightning protection device, make the loop of the long-range remote signalling interface of base be in set a kind of closed off-state.
Wherein there is one section narrow position of insurance at metal dropout safety plate 7 middle parts, and its cross-sectional sizes decides according to the maximum lightning current that the different model lightning protection device allows to pass through, and the big more then cross section of lightning current that allows to pass through need be big more, otherwise then more little.If when lightning current surpassed the maximum that model specification allows to pass through, the place, narrow position of metal dropout safety plate 7 will be played a protective role by fusing.
Metal dropout safety plate 7 uses the joint welding of low temperature tin to be connected with the brace of lightning protection components and parts 2, on the one hand, lightning protection components and parts 2 are when the work protection, if surpass its protective capability scope, the short circuit of will generating heat, adopt low temperature tin just can make this junction operate as normal in range of set temperature, will melt when surpassing this temperature; On the other hand, after the fusing of low temperature tin, be subjected to the effect of thrust spring 6, thereby the junction of joint welding design just can be broken as two parts open-circuit line, makes it can short circuit not cause the bigger disaster of circuit; On the one hand, metal is threaded off safety plate 7 joint welding on lightning protection components and parts 2 braces again, need on the lightning protection device structure to have guaranteed the parts of motion can not be subjected to the interference and the obstruction of any external force, thereby guaranteed that product dropout action can smooth and easy finishing.
Dropout sliding display panel 4 is arranged in the little frame in top versatilely, and the metal dropout safety plate 7 that is fixed on the dropout sliding display panel 4 can slide in little frame 10 with dropout sliding display panel 4.When the lightning protection device fault, the 7 meeting disengagements of metal dropout safety plate are connected with lightning protection components and parts 2 braces, dropout sliding display panel 4 is pushed in the other direction by the effect of thrust spring 6, and the safety plate 7 of thoroughly metal being threaded off disconnects on the line fully with lightning protection components and parts 2 braces 11.Sliding display panel 4 two ends of threading off in addition are provided with different colors, it is red connecting spring terminal, the other end is green, just often green face shows at inefficacy display window 12, the red face end in back of threading off moves to inefficacy display window 12, so finish by normal green and switch, show the operating state of lightning protection device, be convenient to identification and damaged lightning protection device and changed maintenance to the red demonstration of losing efficacy.After dropout sliding display panel 4 is pushed open by thrust spring 6, remote signalling interlock dwang 5 loses by the effect of top, the projection glue position power of dropout sliding display panel 4 and rotates, make remote signalling interlock dwang 5 bottoms leave remote signalling inefficacy action mouth, allow the base remote signalling button actions of lightning protection device, make the long-range remote signalling loop of base finish mutual switching between closed and disconnected, the operating state of the dry contact output alarm indication lightning protection device of a long-range remote signalling control is provided.
