The mechanical trip formula lightning-protection module of described tape jam instruction, described piezoresistance electrode and dropout hardware component electrode have the pin stretching out described organic gel embedding shell respectively.
The mechanical trip formula lightning-protection module of described tape jam instruction, described failure indication module adopts local deterioration indicator light module, described local deterioration indicator light module comprises indicating circuit module and indicator light, one end of described indicating circuit module is connected with low temperature solder joint, the other end is connected with piezoresistance electrode, and described indicator light outwards shows current lightning-protection module running status by the designation hole position on shell.
The mechanical trip formula lightning-protection module of described tape jam instruction, described failure indication module adopts the long-range remote signalling alarm module of switch module, and described long-range remote signalling alarm module carries out the output of remote alarm signal by two electrode pins stretching out shell.
The mechanical trip formula lightning-protection module of described tape jam instruction, described failure indication module adopts the long-range remote signalling alarm module of local deterioration indicator light module and switch module to use simultaneously, described local deterioration indicator light module comprises indicating circuit module and indicator light, one end of described indicating circuit module is connected with low temperature solder joint, the other end is connected with piezoresistance electrode, described indicator light outwards shows current lightning-protection module running status by the designation hole position on shell, described long-range remote signalling alarm module carries out the output of remote alarm signal by two electrode pins stretching out shell.
Beneficial effect:
1. the utility model utilizes a kind of dropout hardware component and piezo-resistance to be connected in series, dropout hardware component one end is connected by low temperature solder joint with piezoresistance electrode point, piezo-resistance entirety have after organic gel embedding with dropout hardware component common enclosure, the dropout hardware component other end connects dropout hardware component electrode, has with piezoresistance electrode the pin stretching out described shell respectively.Overall adopt shell parcel, the overall organic gel embedding of piezo-resistance is connected with dropout hardware component soldered, and by the timely feedback module running status of faulty indication, and the mechanical trip indicated by a kind of tape jam of entirety assembling formation is declined type lightning-protection module.Its preventing principle is exactly that dropout hardware component is connected with piezoresistance electrode low temperature solder joint, low temperature solder joint junction in piezo-resistance because overcurrent or self leakage current or other reasons temperature rise, low temperature solder joint fusing time (110 DEG C ~ 135 DEG C) when temperature is too high, both dropout hardware component and piezo-resistance depart from, thus cut off the connection of piezo-resistance and main circuit, avoid piezo-resistance to cause because effectively main circuit can not be departed from constant temperature to rise and even fire hazard possibility occurs, ensure the normal operation of main circuit.And by faulty indication (comprising status indicator lamp or long-range remote signalling alarm or the two to have concurrently) the miniature lightning-protection module running status of feedback in time, be convenient to pinpoint the problems as early as possible and change as early as possible.
