Description
Technical field
The utility model relates to a kind of power system device technical field, specifically a kind of arcing contact for earthed switch.
Background technology
Earthed switch uses more extensive in high-voltage fence now, it has become one of indispensable component devices in electric power system, and earthed switch is in the time of opening and closing induction current, due to the calcination of electric arc, earthed switch dynamic/static contact scaling loss is serious, is prone to folding failure in the time of opening and closing induction current repeatedly.Now earthed switch demand strengthens gradually, seeks a kind of simple and reasonable for structurely, and the ground connection arcing contact that deciliter ability is strong becomes the technical issues that need to address.
Summary of the invention
The utility model provides a kind of simple and reasonable for structure in order to overcome above-mentioned defect, prevents dynamic/static contact scaling loss, the earthed switch arcing contact of deciliter stable performance.
The technical solution adopted in the utility model is: a kind of earthed switch arcing contact, comprise quiet main contact, moving main contact, moving contact seat and static contact seat, quiet main contact is arranged on static contact seat, moving main contact is arranged on moving contact seat, it is characterized in that: also comprise arcing moving contact and arcing fixed contact, the described rectangular shape of arcing moving contact, bottom is cross bar, top is montant, arcing moving contact is positioned at the rear side of moving main contact, i.e. that side of close static contact seat, its cross bar one end is connected with moving contact seat, the other end stretches out to moving contact seat right side direction, its end is connected with montant is vertical, montant is parallel with moving main contact, cross bar length is 50 millimeters-100 millimeters, described arcing fixed contact is arranged on static contact seat, the right side of quiet main contact, and the position that can coordinate with the montant of arcing moving contact, and arcing fixed contact is parallel with quiet main contact and highly consistent, and its fingertip is U-shaped fingertip.
In the utility model, described arcing moving contact is that circular stainless steel body of rod forging is made, and its cross bar and montant are monolithic construction.
The utility model is provided with arcing moving contact in a side of traditional moving main contact, be provided with in a side of quiet main contact the arcing fixed contact coordinating with arcing moving contact again simultaneously, arcing moving contact is vertical configuration, and be positioned at the rear side of moving main contact, like this, in the time that earthed switch closes, arcing moving contact first contacts with arcing fixed contact, moving main contact contacts with after quiet main contact, so prebreakdown electric arc only burns between the dynamic and static contact of arcing; In the time that earthed switch cut-offs, moving main contact first separates with quiet main contact, and arcing moving contact separates with after arcing fixed contact, only between the dynamic and static contact of arcing, burns so cut-off electric arc.So just can protect sound main contact to avoid electric arc calcination, divide-shut brake stable performance, has improved repeatedly opening and closing induction current ability, increases the service life.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the right view of Fig. 1.
Fig. 3 is that the A of Fig. 1 is to view.
Embodiment
Now by reference to the accompanying drawings the utility model is further described, Fig. 1 is a kind of embodiment of the present utility model, comprise quiet main contact 1, moving main contact 2, moving contact seat 3 and static contact seat 4, quiet main contact 1 is arranged on static contact seat 4, moving main contact 2 is arranged on moving contact seat 3, the utility model also comprises arcing moving contact 5 and arcing fixed contact 6, the described rectangular shape of arcing moving contact 5, bottom is cross bar, top is montant, arcing moving contact 5 is positioned at the rear side of moving main contact 2, i.e. that side of close static contact seat 4, see Fig. 2, its cross bar one end is connected with moving contact seat 3, the other end stretches out to moving contact seat 3 right side directions, its end is connected with montant is vertical, montant is parallel with moving main contact 2, cross bar length is 50 millimeters-100 millimeters, in the present embodiment, the length of cross bar is 52 millimeters, the length of cross bar has determined the distance between montant and moving main contact 2, montant and moving main contact 2 are greater than 50 millimeters for safe distance, can prevent between arcing contact that arc offset is to main contact.Described arcing fixed contact 6 is arranged on static contact seat 4, the right side of quiet main contact 1, and the position that can coordinate with the montant of arcing moving contact 5, and arcing fixed contact 6 is parallel and highly consistent with quiet main contact 1, and its fingertip is U-shaped fingertip, sees Fig. 3.
Arcing moving contact 5 in the present embodiment is made for the circular stainless steel body of rod forges, its cross bar and montant are monolithic construction, and this infrastructure cost is low, durable and be difficult for getting rusty, arcing moving contact 5 can also be that the round bar of copper tungsten material is made, and conducts electricity very well but cost is higher.
Because the utility model is provided with arcing moving contact 5 in a side of traditional moving main contact 2, be provided with in a side of quiet main contact 1 the arcing fixed contact 6 coordinating with arcing moving contact 5 again simultaneously, arcing moving contact 5 is vertical configuration, and be positioned at the rear side of moving main contact 2, like this, in the time that earthed switch closes, arcing moving contact 5 first contacts with arcing fixed contact 6, moving main contact 2 contacts with after quiet main contact 1, so prebreakdown electric arc only burns between the dynamic and static contact of arcing; In the time that earthed switch cut-offs, moving main contact 2 first separates with quiet main contact 1, and arcing moving contact 5 separates with after arcing fixed contact 6, only between the dynamic and static contact of arcing, burns so cut-off electric arc.So just can protect sound main contact 1 to avoid electric arc calcination, divide-shut brake stable performance, has improved repeatedly opening and closing induction current ability, increases the service life.
The utlity model has simple and reasonable for structurely, prevent dynamic/static contact scaling loss, the feature of deciliter stable performance.
