Abstract
The invention discloses a multi-property contact. The multi-property contact comprises a contact part (4), wherein the contact part (4) consists of two or more contact modules (5). Compared with the prior art, the multi-property contact has the advantages that in the design of the contact, multiple contact modules are assembled together to form one contact part, and the multiple contact modules are made from different materials, so that the multiple contact modules are different in strength of properties of electric arc erosion resistance, fusion welding resistance, electric arc rekindling rate, chopping current value and gas content; when the multi-property contact is used, the advantages of the different contact modules can be synthesized, so that the multi-property contact has a great advantage for switching on or off special (capacitive or inductive) currents and is also qualified for switching on or off common currents.
Description
Technical field
The present invention relates to a kind of many performances contact, belong to the power switchgear technical field.
Background technology
Because the vacuum interrupter scope of application is large, its high connecting-disconnecting function requires contact material to have good anti electric arc corrosion ability and resistance fusion welding, low arc reignition rate, particularly low shut off value and air content.These performance requirements are conflicting a bit, obviously do not have a kind of metal can meet the requirement of various aspects of performance simultaneously.The vacuum interrupter now used at present, its structure of contact terminal is single contact, and single contact shut off value is large in use, during for extraordinary character electric current, as can produce overvoltage while cut-offfing capacitive current, system is produced to infringement, some contact connecting-disconnecting function is poor, and anti-Weldability is poor.
Summary of the invention
The object of the invention is to: a kind of many performances contact is provided, and when solving single contact and using under extraordinary character electric current, shut off value is large, can produce overvoltage, and system is produced to infringement, and connecting-disconnecting function is poor, the problem that anti-Weldability is poor.
Technical scheme of the present invention: a kind of many performances contact, include the contact part, this contact part is comprised of the contact module more than 2 or 2.
Above-mentioned a kind of many performances contact, described contact part is nested and is formed by the circular contact module more than 2 or 2.
Above-mentioned a kind of many performances contact, described contact part is inlayed and is formed by the fan-shaped block contact module more than 2 or 2.
Above-mentioned a kind of many performances contact, described contact module is made by chromiumcopper, diamondite, chromiumcopper+trace element or bismuth alloy, a kind of alloy material of every contact module in above-mentioned alloy material made, and the contact module more than 2 or 2 that 2 kinds or two or more alloy material are made forms the contact part.
Above-mentioned a kind of many performances contact, the upper surface of described contact part contacts with the contact tray bottom, and the upper surface of contact tray contacts with the contact base of inverted U-shaped, between contact base and contact tray, is provided with reinforcement.
Beneficial effect of the present invention: compared with prior art, the present invention is in the design of contact, use a plurality of contact modules to combine and form a contact part, and the making material that the plurality of contact module is used is all different, each contact module is at anti electric arc corrosion ability and resistance fusion welding like this, the arc reignition rate, each aspect of performance of shut off value and air content has different powers, so in use, can be mutually between different contact modules comprehensive its different advantage, for extraordinary character electric current (capacitive character, cut-offfing inductive) has advantage greatly, also can be competent at cut-offfing of common current.Circuit breaker chromiumcopper material, shut off value reaches 4-5A, bad but the contact of this kind of material is cut the capacity test effect, reason is that shut off value is too high, produces cut-off overvoltage, no doubt produces and restrikes.For reducing the contact shut off value, a tungsten carbide contact module of welding on the cu cr contact material module, this contact shut off value is low, only has 1.8-2.5A, thereby reaches the purpose that reduces cut-off overvoltage, thereby reduces the generation of restriking.
