Abstract
The invention discloses a process for manufacturing a large-current static contact with small contact resistance, mainly comprising the following step of providing transverse grooves on the body of the static contact lengthwise. The invention is reasonable in process and skillful in design, and the manufacture large-current static contact with small contact resistance effectively reduces the contact resistance due to the plurality of grooves arranged on the body of the static contact lengthwise to increase the number of contact points, thereby improving the current conductivity and being worthy of promotion.
Description
Technical field
The present invention relates to appliance switch manufacturing technology field, specifically, relate to a kind of manufacturing process of fixed contact of on load tap changer.
Background technology
The switch of electricity, usually by moving contact a---fixed contact not, a moving contact---moving contact is formed.The contact of moving contact and fixed contact with separate the Push And Release that promptly forms electricity.Contact form commonly used has: 1. single-point contact, 2. 2 clip types, 3. 4 clip types etc.In existing on load tap changer, above contact form all has employing.But for high voltage, big electric current, particularly require greater than the on load tap changer more than the 800A, more than several contact forms be difficult to meet the demands.The inventor has designed great-current fixed contact terminal for this reason, but uses through reality, finds also existing certain defective aspect contact resistance and the flow conductivity.
Summary of the invention
The objective of the invention is to, provide a kind of and can effectively overcome above-mentioned defective, the manufacturing process of the great-current fixed contact terminal that the contact resistance that designs for the on load tap changer of big electric current is little.
For achieving the above object, the present invention adopts following technical scheme: the manufacturing process of the great-current fixed contact terminal that a kind of contact resistance is little mainly comprises following steps: the fixed contact body provides translot in the longitudinal direction.
Owing to adopt such scheme, be not difficult to draw as drawing a conclusion: technology of the present invention is reasonable, be skillfully constructed, the great-current fixed contact terminal that the contact resistance that produces is little, owing on the length direction of fixed contact body, offer a plurality of translots, increase contact with this and count, thereby reduced contact resistance effectively, strengthen flow conductivity, had promotional value.
Description of drawings
Below in conjunction with drawings and Examples the present invention is described in further detail.
Fig. 1 is the structural representation of the little great-current fixed contact terminal of the contact resistance that produces of the present invention;
Fig. 2 is a fixed contact main body structure schematic diagram;
Fig. 3 is the structural representation of Spring Card.
Embodiment
The manufacturing process of the great-current fixed contact terminal that a kind of contact resistance is little mainly comprises following steps: the fixed contact body provides translot in the longitudinal direction.The structure of the great-current fixed contact terminal that the contact resistance that invention is produced below in conjunction with accompanying drawing is little describes in further detail.Referring to Fig. 2, fixed contact body 10 is the rectangular tube of " V " shape opening, and the contact contact site offers " V " shape groove 12, and it can increase contact pressure, makes contact more reliable, and flow conductivity strengthens.Body 10 has a plurality of translots 11 in the longitudinal direction in addition, increases the contact contact with this and counts, and reduces contact resistance, strengthens flow conductivity.Referring to Fig. 3, Spring Card 20 adopts and fixed contact body 10 analog structures.Referring to Fig. 1, Spring Card 20 is arranged in the fixed contact body 10, and both adopt the riveted joint mode.
