Abstract
The utility model discloses a high-current static contact with reliable installation, mainly consisting of a static contact and a spring clamp within the static contact and characterized in that the spring clamp adopts the similar structure with the static contact. The utility model has reasonable structure and novel idea. Due to the similar structure of spring clamp with the static contact, the whole structure is simple; and the riveting way to be communicated with the static contact makes the installation more convenient and reliable with highly promotional value.
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, 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 purpose of this utility model is, provide a kind of and can effectively overcome above-mentioned defective, for the on load tap changer of big electric current design simple in structure, reliable great-current fixed contact terminal is installed.
For achieving the above object, the utility model adopts following technical scheme: the reliable great-current fixed contact terminal of a kind of installation, mainly form by fixed contact body and the Spring Card that is arranged in it, and it is characterized in that: Spring Card adopts the structure similar to the fixed contact body.
Because adopt such scheme, be not difficult to draw as drawing a conclusion: the utility model is rational in infrastructure, is skillfully constructed, 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 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 reliable great-current fixed contact terminal of a kind of installation mainly is made up of fixed contact body and the Spring Card that is arranged in it, and it is characterized in that: Spring Card adopts the structure similar to the fixed contact body.
