embodiment:
Single the mechanical trip lightning protection device of the present embodiment, comprises power supply contact terminal 2, switch module Metallic rod 3, piezo-resistance 4, piezo-resistance tripping electrode 5, switch module 6, floatless switch component lines plate 7, five metals takes off mouth shell fragment 8, power supply terminal 9, remote signalling terminal 10.The both sides of piezo-resistance are fitted with the piezoresistance electrode stretched out respectively, described piezo-resistance one lateral electrode connects power supply terminal (electrode) by the mode that high temperature welding wire welds and exports, opposite side piezoresistance electrode connects five metals dropout shell fragment by the pad mode of low temperature welding wire, described five metals dropout shell fragment connects power supply terminal (electrode) by the mode of spot welding and exports, and then integral installation fits in base shell 1.
Described lightning protection device adopts soldered mechanical trip technology.
Described piezoresistance electrode is connected power supply terminal (electrode) with dropout five metals shell fragment electrode respectively by the mode that spot welding or high temperature welding wire are welded and is connected with outside.
Described piezo-resistance can select monolithic, and biplate also can be selected in parallel.When selecting biplate in parallel, the electrode after parallel connection in the middle of two panels piezo-resistance connects dropout five metals shell fragment as public electrode, and after parallel connection, two lateral electrodes of piezo-resistance entirety are connected with same binding post (electrode).
The long-range remote signalling alarm function of described switch module and five metals dropout shell fragment and alarm terminal with the use of, carry out long-range remote signals output.
Wide × thick size of described dropout five metals shell fragment is respectively: 7 × 0.5mm, width error scope ± 0.5mm.
Specific works process as shown in Figure 1, when overvoltage pulse arrives, carry out thunder energy between two power supply terminals (electrode) by 2 and 9 to release, piezo-resistance is high-impedance state under normal circumstances, when there being lightning overvoltage pulse to arrive, become low resistive state instantaneously, overvoltage of releasing, thus the lightning protection effect played equipment, exported by electrode pin through the residue low pulse voltage of releasing.Normal work is that dropout phenomenon can not occur the eutectic welding contact that pressure sensitive electrodes 5 and five metals take off between mouthful shell fragment 8, and whole lightning-protection module normally works.Alarm signal exports with the switching value of switch module normally closed (or often opening) signal.
When lightning current is excessive or power-supply system exists short circuit current or piezo-resistance poor-performing and there is many other reasonses such as leakage current and cause piezo-resistance to continue overcurrent heating and cause temperature to raise, low temperature solder joint absorbs heat, when the heat absorbed reaches the fusion temperature of low temperature solder joint, low temperature solder joint melts, five metals dropout shell fragment and piezo-resistance depart from, thus cut off contacting of piezo-resistance and main circuit.Alarm signal is often opened (or often open be converted to normally closed) signal export with normally closed being converted to of the alternation switch amount of switch module.
Technological means disclosed in the utility model scheme is not limited only to the technological means disclosed in technique scheme, also comprises and is equal to by above technical characteristic the technical scheme that replacement forms.Unaccomplished matter of the present utility model, belongs to the common practise of those skilled in the art.
