Description
Technical field
The present invention relates to a kind of lightning-protection module, it is multi-thread in length and breadth to the multifunctional lightning protection module of full guard, vertical protection, cross-protection to relate in particular to railway signal.Itself and special-purpose lightning protection base gang are realized the lightning protection to systems such as railway signals.
Background technology
At present, have only a piezo-resistance (MOV) or discharge tube of a piezo-resistance series connection in the lightning-protection module that generally uses.This form will be carried out full guard in length and breadth to a pair of holding wire; must use three modules could realize (as shown in Figure 6); this can take than large space; strengthen installation difficulty; sometimes even can't install; the wiring meeting of lightning protection device simultaneously is longer, and this will cause deboost to strengthen, and reduce the protection effect.Owing to use three independently modules, their consistency can't guarantee, when overvoltage was invaded, difference start-up time between three modules was bigger, and this will be difficult to reach the protection effect of expection.
Summary of the invention
The purpose of this invention is to provide a kind of multifunctional lightning protection module; it not only has multi-thread preferably in length and breadth to the full guard lightning protection function; can also realize vertical protection and cross-protection lightning protection function respectively, and have overtemperature protection, overcurrent protection, deterioration indication and alarm function.The weak point of existing lightning-protection module and the technical problem of existence have been solved.
The present invention solves the problems of the technologies described above to adopt following technical scheme: a kind of multifunctional lightning protection module, on the cavity inner support that shell and base plate form, comprise lightning protection circuit, and have on the base plate to connect lightning protection circuit in one group, connect the inserted sheet of base outward.It is characterized in that: the dropout protective device that also has overtemperature protection, overcurrent protection, deterioration indication and alarm function.
Described lightning protection circuit, be a pair of holding wire with ground wire between connect respectively a piezo-resistance, a discharge tube, and the piezo-resistance of connecting respectively between piezo-resistance of series connection between a pair of holding wire, discharge tube or holding wire and ground wire, discharge tube or only between holding wire piezo-resistance of series connection, a discharge tube constitute.Three piezo-resistances and three discharge tubes are installed in lightning-protection module, module can realize a pair of line in length and breadth to full guard; Two piezo-resistances and two discharge tubes are installed in lightning-protection module, and a module can realize the vertical protection of a pair of line, and a piezo-resistance and a discharge tube are installed in lightning-protection module, and a module can realize the cross-protection of a pair of line; It is little to have volume, characteristics easy for installation; Because piezo-resistance and discharge tube are installed in the module simultaneously; connection line between them is the shortest; and can match the lightning protection component in each module during production and assembly, make the parameter basically identical between each element in the module, can reach comparatively ideal protection effect.
Described dropout protective device, adopt the interlock form of threading off in flakes, by each piezo-resistance on the support, thread off an end in flakes with after inserted sheet is electrically connected, weld with the electrode slice of piezo-resistance mutually by the release lever with excess current protective function at the middle part, the two sides of the other end in flakes of threading off, and one side is pushed down a stage clip that places in the support top slide, slidably displaying block is corresponding with one for another side, and displaying block is fixed on the support by a small pressure spring; Three groups of dropouts all use same mode corresponding with this displaying block in flakes; Coat mark on displaying block, the part that is coated with mark is corresponding with the window of module housing.
Its operation principle and the course of work are: when arbitrary piezo-resistance wears out overheated or be hit damage, coupled release lever and the fusing of the solder joint of electrode slice, thread off and under the effect of stage clip, make the thorough and electrode slice disengaging of special release lever in flakes, simultaneously displaying block is pushed open a segment distance, the display area of alignment modules shell window is changed, the display window variable color, representation module damages; When the lightning current that passes through on the piezo-resistance surpasses set point, release lever is subjected to heavy current impact and fuses, and makes the thorough and electrode slice disengaging of release lever, threads off and also displaying block is pushed open a segment distance in flakes simultaneously, the displaying block variable color of module window simultaneously, representation module damages.Key of the present invention be arbitrary dropout an end is all corresponding with same displaying block in flakes, losing efficacy in promptly arbitrary road all can have same display result.
In order further to realize that such scheme improves, the remote signalling bar also is set, because just often the top of remote signalling bar is shown piece and pushes down, when displaying block is open when being subjected to displacement, the remote signalling bar up moves under the effect of base switch, and the base switch motion realizes alarm function.
In order to realize that further such scheme improves, lightning-protection module also has anti-misplug function, it is at the module base plate two discriminating pins to be installed, its effect is a module of distinguishing different stage by the different directions of two discriminating pins, discriminating pin jack with base is an one-to-one relationship simultaneously, the module of different parameters just can not be inserted on the same base like this, makes things convenient for installation and maintenance.
Good effect of the present invention is, owing to adopt the protective device of the interlock form of threading off in flakes, when any one piezo-resistance wears out overheated or be hit damage, the not only solder joint of release lever and electrode slice fusing, threading off makes the thorough and electrode slice disengaging of special release lever in flakes under the effect of stage clip, simultaneously displaying block is pushed open a segment distance, and the position of alignment modules shell window is changed, the display window variable color, representation module damages; And by remote signalling bar realization alarm function.In single module, realize multi-threadly respectively, and realize overtemperature protection, overcurrent protection, deterioration indication, alarm function, have reliable operation, easy to use, characteristics that the life-span is long simultaneously in length and breadth to full guard, vertical protection, cross-protection.
Further specify the present invention below in conjunction with embodiment and accompanying drawing.
