Abstract

The utility model discloses a remote signal indication device for an anti-thunder product. A pin 3 of microswitches S is connected with an NC terminal of a remote signal interface P1. A pin 2 of the microswitches S is connected with a COM terminal of the remote signal interface P1. A pin 1 of the microswitches S is connected with an NO terminal of the remote signal interface P1. The microswitches S are one or two or more microswitches S connected in a manner that the normally closed terminals are connected in series and the normally opened terminals are connected in parallel. According to the utility model, the microswitches are used as signal switching devices, and the remote signal indication device has the advantages of simple structure and accurate and reliable indication.

Description

A kind of lightning-protected product remote signalling indicating device
Technical field
The invention belongs to lightning protection and detect indicating equipment technical field, especially relate to the reliable lightning-protected product remote signalling of a kind of practicality indicating device.Be convenient to, on lightning-protected product, product failure is carried out to remote alarm.
Background technology
Along with lightning-protected product is more and more used, it is more and more simpler and easy convenient that the indication that lightning protection was lost efficacy is also required, from early stage metal clips linked-baffle, by fenestella, observe the lightning-protected product with pilot lamp afterwards, no longer the satisfy the demand mode of field observation of client, so remote signalling interface is used on lightning-protected product; And current remote signals switching mode adopts relay more.Relay volume is large, and space requirement is high, and the more difficult control of cost, therefore need a kind of small size cheaply mode replace the remote signaling function of Control.
Summary of the invention
The purpose of this utility model provide with improving the deficiency of prior art a kind of by microswitch as signal shifter part, simple in structure, indicate the indicating device of lightning-protected product remote signalling accurately and reliably.
The purpose of this utility model is achieved in that a kind of lightning-protected product remote signalling indicating device, is characterized in that the NC that 3 pin by microswitch S meet remote signalling interface P1 holds, and 2 pin connect the COM end of remote signalling interface P1, and 1 pin connects the NO end of remote signalling interface P1.
In order further to realize the purpose of this utility model, can be that described microswitch S is normal-closed end serial connection, the Chang Kaiduan parallel connection of one or 2 above microswitch S.
The utility model with compared with the prior art there is following distinguishing feature and good effect: the NC that the utility model adopts 3 pin by microswitch S to meet remote signalling interface P1 holds, 2 pin connect the COM end of remote signalling interface P1, 1 pin connects the NO end of remote signalling interface P1, the triggering button of the microswitch S of this device is contacted with the heat dropout shell fragment in lightning protection device, lightning protection device is when being subject to continuing heavy current impact, earial drainage element heating is to losing efficacy, thermal release device starts during this time, the action reed of the metal clips compressing microswitch S flicking switches its signal, make remote signalling interface P1 trigger alarm signal, realize the remote signalling alarm function that lightning protection device lost efficacy, microswitch S is that normal-closed end serial connection, the Chang Kaiduan of one or 2 above microswitch S is in parallel, can realize the object that detects a plurality of lightning protection devices, reduces costs.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is another kind of structural representation of the present utility model.
Embodiment
Embodiment 1, and a kind of lightning-protected product remote signalling indicating device, with reference to Fig. 1, is that the NC that 3 pin by microswitch S meet remote signalling interface P1 holds, and 2 pin connect the COM end of remote signalling interface P1, and 1 pin connects the NO end of remote signalling interface P1, and this forms a kind of structure of the present utility model.
Embodiment 2, a kind of lightning-protected product remote signalling indicating device, with reference to Fig. 2, the present embodiment adopts 4 microswitch S1, S2, S3, S4 serial connection, be 3 pin that 2 pin of microswitch S1 meet microswitch S2,3 pin of microswitch S2 connect 2 pin of microswitch S3,3 pin of microswitch S3 connect 2 pin of microswitch S4,3 pin of microswitch S1 connect the NC end of remote signalling interface P1,2 pin of microswitch S4 connect the COM end of remote signalling interface P1,1 pin of micro-letter switch S 1, S2, S3, S4 connects the NO end of remote signalling interface P1, and this forms a kind of structure of the present utility model.
