Abstract
The invention discloses a process for manufacturing a large-current static contact which is reliable in installation, mainly comprising the following step of providing a spring clip which has a structure similar to that of the body of the static contact. The invention is reasonable in process and skillful in design, and the manufactured large-current static contact which is reliable in installation, for adopting a spring clip which has a structure similar to that of the body of the static contact, is simple in whole structure, and as the spring clip is in rivet connection with the body of the static contact, is simple, convenient and reliable in installation, thereby being worth 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, and after discovery Spring Card and the combination of fixed contact body, overall structure is comparatively complicated, is difficult to reliable installation.
Summary of the invention
The objective of the invention is to, provide a kind of and can effectively overcome above-mentioned defective, simple in structure, the manufacturing process that reliable great-current fixed contact terminal is installed that design for the on load tap changer of big electric current.
For achieving the above object, the present invention adopts following technical scheme: a kind of manufacturing process that reliable great-current fixed contact terminal is installed mainly comprises following steps: the Spring Card that provides adopts the structure similar to the fixed contact body.
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 reliable great-current fixed contact terminal of the installation that produces, because Spring Card adopts the structure similar to the fixed contact body, makes overall structure simple, itself and fixed contact body adopt the riveted joint mode, make simple installation, reliable, have 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 reliable great-current fixed contact terminal of installation 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
A kind of manufacturing process that reliable great-current fixed contact terminal is installed mainly comprises following steps: the Spring Card that provides adopts the structure similar to the fixed contact body.The structure of the reliable great-current fixed contact terminal of installation that invention is produced below in conjunction with accompanying drawing 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.
