Spring Bound Quincunx Contact T2 Copper Silver-Plated Grounding Rod
Product introduction:
Design idea of plum blossom contact:
Some matters needing attention in the design of electric contact. Take the plum blossom contact composed of spring clamp and milling petal contact finger as an example, aiming at the position where the contact finger clamps the spring; Install insulating mat at the rear end of the contact finger; The difference between the size of the inner circle of the milling finger and the outer circle of the single end and whether the milling finger can be used in disorder are analyzed, and the methods to reduce the contact resistance of the finger are proposed.
The high-voltage switchgear shall break the fault current in case of grid fault; During normal operation, load current shall also be switched on and off, and there must be obvious breaking points, and separable contacts shall be equipped. In addition, in order to facilitate assembly and docking. The high-voltage switchgear will also be provided with butt contacts at appropriate positions; A sliding contact is also arranged between the moving part and the stationary part of the conductive body. There is contact surface resistance for both separable contact, butt contact and sliding contact. The size and stability of the contact resistance have a significant impact on the temperature rise of the switchgear during long-term operation and the dynamic thermal stability under the impact of fault current. There are many factors that determine the contact resistance, such as contact surface condition, contact pressure, material hardness and material resistivity. Throughout many factors, contact pressure is an important factor that has a wide range of changes and can be predicted by designers. Now take the plum blossom contact, which is tightly clamped by spring and composed of milled petal contact finger, as an example, to talk about the design essentials and avoid entering the wrong zone. The so-called "milling of the touch finger" means turning the outer wheel of the touch finger into a blank, and then milling it evenly into pieces with a milling machine.

Manufacturing process of plum blossom contact:
1. Electrolytic polishing of non-magnetic stainless steel bracket
2. Binding of non-magnetic stainless steel ring tension spring
3. The contact piece is finished with T2 copper plate, the surface is coated with thick silver, and it will not change color for a long time after anti-color treatment (bundled quincunx contact 630A-4000A)

Technical characteristics:
According to the amount of silver cadmium oxide in the contact, it is 88%, 85%, 40% and 30% respectively. The input voltage of the cam controller is not higher than 109% of the rated voltage, and there is no obvious fluctuation. When the environmental pollution is light, the electrical life of the contact containing 88%, 85% and 40% silver cadmium oxide is more than 100000 times, and the electrical life of the contact containing 30% silver cadmium oxide is more than 50000 times. The mixed silver point and copper base point contact is applicable to the cam controller with less opening and closing times.

Structural features:
1. Electrolytic polishing of non-magnetic stainless steel bracket
2. Binding of non-magnetic stainless steel ring tension spring:the ring stainless steel spring has uniform pressure, which can ensure that the radial elastic deformation of each contact piece has uniform contact pressure, so as to effectively control the contact resistance, reduce the heating of the contact part, and improve the reliability and safety of conductivity
3. The contact piece is finished with T2 copper plate, and the surface is coated with thick silver. After anti-discoloration treatment, it will not change color for a long time, and the shape is beautiful.
4. The ring spring pressure is uniform
5. Imported non-magnetic stainless steel material is used to avoid eddy current
6. Brush plating with thick silver, strong wear resistance
7. Anti-changing treatment to avoid oxidation and falling off of silver layer
