Abstract
The utility model discloses a high current static contact of big contact pressure, particularly consisting of a static contact main body and a spring card positioned in the static contact main body, which is characterized in that: The contact site of static contact main body is provided with a 'V'- shaped groove. The utility model has reasonable structure and skilled ideas, provided with 'V'- shaped groove at the contact site of the static contact main body, thereby increasing the contact pressure, making the contacts more reliable, enhancing the conductivity and having great value of popularization.
Description
Technical field
The utility model relates to the appliance switch technical field, specifically, relates to a kind 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 reliability and the flow conductivity.
Summary of the invention
The purpose of this utility model is, provides a kind of and can effectively overcome above-mentioned defective, the big great-current fixed contact terminal of contact pressure that designs for the on load tap changer of big electric current.
For achieving the above object, the utility model adopts following technical scheme: the great-current fixed contact terminal that a kind of contact pressure is big, mainly be made up of fixed contact body and the Spring Card that is arranged in it, it is characterized in that: the contact site of fixed contact body offers " V " shape groove.
Because adopt such scheme, be not difficult to draw as drawing a conclusion: the utility model is rational in infrastructure, is skillfully constructed, owing to offer " V " shape groove in the contact site of fixed contact body, thereby increased contact pressure, make contact more reliable, strengthen flow conductivity, had promotional value.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a fixed contact main body structure schematic diagram;
Fig. 3 is the structural representation of Spring Card.
Embodiment
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.
Claims (1)
1, the big great-current fixed contact terminal of a kind of contact pressure mainly is made up of fixed contact body and the Spring Card that is arranged in it, and it is characterized in that: the contact site of fixed contact body offers " V " shape groove.
