A kind of explosion type circuit break switch, it comprises an insulating sleeve, at least two mutually insulateds be fixed in the insulating sleeve one end inner chamber conductive seat as the major loop electrode conductor, also have one to be installed in and to be used for promoting the igniter that moving contact moves in the conductive seat one end inner chamber; Moving contact is comprised of electric conductor and insulator, and this insulator is near igniter; The end face of electric conductor is over against the installation conductive seat of the insulating sleeve sliding cavity that moving contact moves that is used for relative to an end.
Described explosion type circuit break switch, its conductive seat is comprised of binding post and arc Conductive holding element; The outer surface of this arc Conductive holding element and insulating sleeve internal chamber wall have one section to fit, and the interior contoured surface of arc Conductive holding element and the outer surface of moving contact fit.
Described explosion type circuit break switch, its binding post and arc Conductive holding element are the integral body that is cast into, or the integral body that is welded into.
Described explosion type circuit break switch, the inner chamber section of its insulating sleeve is the figure of eight.
Described explosion type circuit break switch, its conductive seat have two, and one of them is first order conductive seat, and another is second level conductive seat, are used for being connected with the circuit respective electrode respectively.
Described explosion type circuit break switch, its conductive seat are to be fixed in the inner chamber of insulating sleeve by dog screw, or conductive seat is that tight fit is pressed in the inner chamber of insulating sleeve; Described conductive seat is that interference fit is connected with moving contact.
Described explosion type circuit break switch, the sliding cavity of its insulating sleeve and moving contact are matched in clearance, and the gap is less than or equal to 0.5 millimeter.
Described explosion type circuit break switch has air vent hole on the sliding cavity outer face of its insulating sleeve.
Described explosion type circuit break switch, the insulator of its insulating sleeve and moving contact are the insulating material of anti-electric arc; Described conductive seat is high-intensity electric conducting material.
The basic functional principle of described explosion type circuit break switch: it is to utilize the characteristics that the explosive charge reaction speed is fast, the acting ability is strong, when electric system needs protection, the triggering signal ignition charge rapidly with moving contact fried from, mobile, reach the purpose of protection electric system.That is: because electric detonator in the enormous impact power that explosion time produces, makes the moving contact that is between the conductive seat produce axial motion, and the insulated part of moving contact contacts with conductive seat rapidly, switch disconnects fully.
Advantage of the present invention and technique effect are: simple in structure, shock-resistant, breaking speed is fast, reliability is high and easy to maintenance; Explosion type circuit break switch is applicable to various automatically controlled occasions, is specially adapted to the automatically control of ship electricity.The impact that explosion type circuit break switch can bear hundreds of gravity inertial acceleration is that moving contact and conductive seat are interference fit, for this reason, no matter switch is in not operating state or operating state, can tolerate the impact of hundreds of gravity inertial acceleration of moment.Because this invention is the multi-break structure, therefore, but the electric pressure of its disjunction is significantly increased simultaneously.
