Abstract
The utility model provides a static arc contact terminal in the technical field of power supply unit, and aims to solve the problems of high cost and low performance-price ratio in the present static arc contact terminal. The static arc contact terminal comprises a contact terminal rod body at the top end of which a protective layer is arranged and preferably adopts a copper tungsten alloy layer, and copper cladding is arranged outside the protective layer and the contact terminal rod body. The copper tungsten alloy layer achieves the function of arc resistance, and the copper cladding can enhance the conductivity of the static arc contact terminal. The static arc contact terminal can be used for high-voltage sulfur hexafluoride circuit breakers, and can not only resist arc intensity but also satisfy the requirements of the arc contact terminal of the high-voltage sulfur hexafluoride circuit breaker for inducing arc current, thereby greatly improving both the reliability and economical efficiency of the high-voltage sulfur hexafluoride circuit breaker.
Description
Technical field
The utility model relates to a kind of quiet arc contact, and relating in particular to a kind of high pressure sulfur hexafluoride breaker that is used for has the quiet arc contact of drainage to electric arc, belongs to the power supply unit technical field.
Background technology
The present quiet arc contact in the high pressure sulfur hexafluoride breaker, the outer Cu-Cr alloy layer that coats earlier of contact body, outsourcing copper-tungsten layer structure again, this kind quiet arc contact cost is very high, and cost performance is lower.
The utility model content
For solving in the prior art, quiet arc contact cost height, the problem that cost performance is low the utility model proposes a kind of quiet arc contact, both anti-arc stiffness, and cost performance is high again.
For solving above technical problem, a kind of quiet arc contact provided by the utility model comprises the contact stem body, and the top of contact stem body is provided with protective layer, and the appearance that protective layer reaches the contact stem body outward all is coated with copper coating.
Protective layer is preferably the copper-tungsten layer.
With respect to prior art; the utility model has been obtained following beneficial effect: at the top of contact stem body sintering layer protective layer; can guarantee that the quiet arc contact does not deform under electrodynamic effect; outer field copper coating can increase the conductivity of quiet arc contact, thereby the reliability of high pressure sulfur hexafluoride breaker and economy are improved greatly.Copper-tungsten has the performance of good anti-electric arc, and protective layer adopts the copper-tungsten layer to play the effect of anti-electric arc.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of a kind of quiet arc contact of the utility model.
Among the figure: 1 contact stem body, 2 protective layers, 3 copper coatings.
Embodiment
As shown in Figure 1; quiet arc contact of the present utility model; the material that contact stem body 1 adopts is a round steel; guaranteed the mechanical strength of contact; the top sintering of contact stem body 1 has the copper-tungsten layer as protective layer 2, thereby has guaranteed that the quiet arc contact does not deform under electrodynamic effect, and the copper-tungsten layer has played the effect of anti-electric arc; the appearance that the copper-tungsten layer reaches the contact stem body outward all is coated with copper coating 3, and copper coating 3 can increase the conductivity of quiet arc contact again.The not only anti-arc stiffness of quiet arc contact of the present utility model but also can satisfy the needs of high pressure sulfur hexafluoride breaker arcing contact striking arc electric current improves the reliability of high pressure sulfur hexafluoride breaker and economy greatly.
When the moving arcing contact of high pressure sulfur hexafluoride breaker minute, close a floodgate when having electric arc to take place, this quiet arc contact has played electric arc has been drained into earlier on the quiet arc contact stem, because copper-tungsten has the ability of anti-electric arc, can protect fixed contact to exempt from by electrical arc erosion.
In addition to the implementation, the utility model can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all fall into the protection range of the utility model requirement.
Claims (2)
1. a quiet arc contact comprises the contact stem body, it is characterized in that, the top of contact stem body is provided with protective layer, and the appearance that protective layer reaches the contact stem body outward all is coated with copper coating.
2. a kind of quiet arc contact according to claim 1 is characterized in that described protective layer is the copper-tungsten layer.
