Technical field
The present invention relates to a kind of explosion type disconnect, is a kind of normally closed switch, belongs to the electric switch technical field, is applicable to various automatically controlled occasions, is specially adapted to the control automatically of ship electricity.
Background technology
Existing conventional low contactor mainly is to make moving contact realize that through certain stroke contact disconnects by electromagnetic mechanism or spring mechanism, under the certain situation of current-carrying part unit volume ampacity, because traditional contactor needs the driving mechanism of the relative current-carrying part several times of volume, causes the overall dimension of traditional contactor and quality can't further dwindle always.And the conventional low contactor can't bear the environment of HI high impact vibration owing to be subjected to the restriction of self structure, volume and quality.As the protection switch that uses in the ship electric control, it is fast to require switch to have opening speed, and bulking value is little, characteristics such as shock-resistant and reliability height, and the existing mechanical switch can not meet the demands.
The patent No. is that the explosion type disconnect of ZL200820067360.3 has obviously than conventional low contactor volume and dwindles, but is subjected to its structural limitations, and its disjunction electric pressure can't further improve.
Summary of the invention
The objective of the invention is: the explosion type that a kind of size is little, in light weight, simple in structure, shock-resistant, breaking speed is fast, reliability is high and easy to maintenance disconnect is provided.
Technical scheme of the present invention is as follows:
A kind of explosion type disconnect, 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 the conductive seat one end inner chamber and to be used to promote the igniter that moving contact moves; Moving contact is made up 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 disconnect, its conductive seat is made up 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 disconnect, 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 disconnect, the inner chamber section of its insulating sleeve is the figure of eight.
Described explosion type disconnect, its conductive seat have two, and one of them is a first order conductive seat, and another is a second level conductive seat, are used for being connected with the circuit respective electrode respectively.
Described explosion type disconnect, 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 disconnect, the sliding cavity of its insulating sleeve and moving contact are matched in clearance, and the gap is smaller or equal to 0.5 millimeter.
Described explosion type disconnect has air vent hole on the sliding cavity outer face of its insulating sleeve.
Described explosion type disconnect, 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 disconnect: 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, move, 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; The explosion type disconnect is applicable to various automatically controlled occasions, is specially adapted to the control automatically of ship electricity.The impact that the explosion type disconnect 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.
