Features of neutral point outdoor isolating switch

Neutral point isolating switch is a switching device that is mainly used for "isolated power supply, switching operation, and connecting and cutting off small current circuits" without arc extinguishing function. Disconnectors are widely used and require high reliability
1. The structure of the bearing turntable is improved, so that the bearing seat can realize the waterproof function. It is also equipped with an oil injection hole and an adjusting screw, the switch has a strong integrity and the maintenance is simpler and more convenient.

2. The copper welding process is adopted between the conductive rod and the contact, and between the conductive rod and the contact finger seat. In addition, a soft connection is installed between the contact finger and the contact finger seat, so that the main circuit resistance of the product is significantly higher than that of the screw connection. Reduced, thereby reducing the heating problem of the contacts during operation. The grounding guide rod is made of aluminum alloy with excellent conductivity, the contact part is made of copper castings, and the connection between the conductive rod and the base and between the grounding contact finger and the contact finger seat are all equipped with soft connections, so the conductivity of the grounding loop is greatly enhanced.

3. The conductive exposed parts are all treated with copper-plated silver surface treatment process, silver-plated treatment, smooth surface, beautiful, strong corrosion resistance, durable.

4. Improve the shaft and hole matching method: the iron-copper matching is changed to copper-copper matching or stainless steel-copper matching, which solves the seizure phenomenon that occurs in long-term outdoor use. The exposed standard parts are made of stainless steel; the metal parts are treated with hot-dip galvanizing to ensure the corrosion resistance of the switch.
