Abstract
The utility model relates to a high-vacuum, high-voltage, large-current relay. On the basis of a high-vacuum, high-voltage, large-current relay which is provided with a glass housing, a normally open contact, a normally closed contact and a movable contact, an additional contact made of graphite, an electric conducting material which is high temperature resistant and can not stick is fastened on the end surface of the normally open contact positioned inside the glass housing so as to form a normally open contact of a composite body structure with the original normally open contact; as a consequence, the problem of the failure of a relay caused by the melting of a contact is solved. The utility model is suitable for the field of high-voltage and strong-electricity.
Description
The utility model relates to vacuum electron device, particularly about the architecture advances of high vacuum, high voltage, high-current relay.
Need in some certain electric apparatus with high vacuum, high voltage, high-current relay, for example heart has just been stopped to jump the heart buoyant apparatus that patient does to rescue, normally-closed contact by high vacuum, high voltage, high-current relay, allow an electric capacity fill the 6-8 kilovoltage with, and then the closure by normally opened contact, allow the voltage on the electric capacity that human heart is carried out instantaneous discharge, dash with computer and irritate heart, make heart recover to beat.Because the structure of existing high vacuum, high voltage, high-current relay is generally armature contact, normally opened contact, normally-closed contact all are sealed in the glass shell that vacuumizes and each contact has the pin that passes glass shell respectively.Because operating voltage height; transient current by the contact when normally opened contact is closed is very big; when therefore normally opened contact is closed; can produce the electric arc of extreme temperatures between the contact; so existing high vacuum, high voltage, high-current relay regular meeting produce melting phenomenon; make normally opened contact be lived by melting welding and can not disconnect once more; cause relay to lose efficacy; such relay is if be applied to buoyant apparatus; relay will electric capacity can not be charged once more because of can not reset; cause buoyant apparatus to lose efficacy, serious meeting makes patient can not get in time rescuing and death.
The purpose of this utility model is to solve the Problem of Failure that above-mentioned fusion causes, a kind of simple in structure, high vacuum of high reliability, high voltage, high-current relay are provided.
The purpose of this utility model is achieved in that on above-mentioned existing high vacuum with glass shell, normally opened contact, normally-closed contact, armature contact, high voltage, high-current relay basis, on the normally opened contact end face that is positioned at glass shell and facing movament contact, set up with supplementary contact high temperature resistant, that can not bonding electric conducting material make, constitute the normally opened contact of complex structure jointly with former normally opened contact.
Like this, under arcing,, can not produce melting phenomenon, fundamentally solve the Problem of Failure of high vacuum, high voltage, high-current relay because of the normally opened contact of complex structure has the supplementary contact protection.Obvious high vacuum, high voltage, high-current relay as compared with the past, reliability greatly improves.
Fig. 1 is the structural representation of the utility model one embodiment.
Further introduce the utility model below in conjunction with accompanying drawing.
Referring to Fig. 1, present embodiment is on the basis of, high voltage true at existing high electricity with glass shell 1, normally opened contact 2, normally-closed contact 3 and armature contact 4, high-current relay, on the end face of the normally opened contact 2 that is positioned at glass shell 1 and facing movament contact 4, fastening one with high temperature resistant, electric conducting material that can not the be bonding supplementary contact 5 made of graphite for example, with the former normally opened contact 2 common normally opened contacts that constitute complex structures.Relay with this spline structure can not produce the Problem of Failure of contact fusion, thereby has obtained very high reliability.
Claims (1)
1, a kind of high vacuum, high voltage, high-current relay, comprise glass shell (1), normally opened contact (2), normally-closed contact (3) and armature contact (4), it is characterized in that also comprising a supplementary contact (5) made from electric conducting material graphite high temperature resistant, can not be bonding, this supplementary contact (5) is fastened on the end face of the normally opened contact (2) that is positioned at glass shell (1) and facing movament contact (4), constitutes the normally opened contact of complex structure jointly with above-mentioned normally opened contact (2).
