Shaanxi Province high voltage vacuum circuit breaker ZW32-12 / 630A

ZW32-12 Product Overview Shaanxi Province high voltage vacuum circuit breaker ZW32-12 / 630AZW32-12 outdoor high-voltage vacuum circuit breaker (also known as: outdoor column vacuum switch) for three-phase AC 50Hz, rated voltage of 12kV power system, can breaking, closing the line load current, overload current and short circuit current. Mainly used for breaking, closing electronic system load current, overload current and short circuit current. For substation and industrial and mining enterprises distribution system for protection and control purposes, and rural power grids frequent operation place. But also as a grid disconnect switches, after the installation of the controller, can realize distribution automation, ZW32 vacuum breaker, according to user requirements, optional CT overcurrent protection, isolation switch, outdoor PT, intelligent controller (see Watchdog), metering tank means, to meet the needs of a variety of occasions. Vacuum circuit breaker in accordance with the operating mechanism, is divided into two spring operating mechanism and the permanent operator. Model ZW32-12T and ZW32-12M. Shaanxi Province high voltage vacuum circuit breaker ZW32-12 / 630AZW32-12 structural features 1, vacuum circuit breaker fully enclosed structure, good sealing performance, help to improve moisture, condensation performance, especially for use in cold or wet areas. 2, ZW32 vacuum breaker three-phase pillar structure, a stable and reliable breaking performance, no fire and explosion hazards, maintenance-free, small size, light weight and so long service life. 3, the shell is made of high quality stainless steel or ordinary copper rust treatment process by DACROMET then spray varnish from UV-resistant, excellent corrosion protection products, salt spray and other environmental resistance. 4, the circuit breaker may be provided two-phase or three-phase current transformer for overcurrent or short-circuit protection, can also provide a current pickup signals to the intelligent controller; according to user requirements can be equipped with metering current transformer. 5, the insulation part epoxy and silicone rubber load insulation, insulation levels, and strong anti-contamination ability, resistant to ozone, UV, hydrophobic and anti-high temperature capability. Cabinets without transformer oil, no sulfur hexafluoride gas, oil-free transformation and meet environmental requirements. 6, the operating mechanism, both manual and electric points, you need to install the remote control device, to add and avoid closing surge devices. External power supply power less than 70W, easy backup power supply. Design unique cushioning devices, high performance, small rebound, and low noise. 7, the interrupter technique using special stainless steel brazing, lunch plating, welding, high quality, reliable, leak rate. The use of the production process special ceramic metal formulations and advanced ceramic metallization process to ensure air tightness, tensile strength greater than 130Mpa, complete a closed row. 8 current transformers using high-quality magnetic materials and epoxy resin and silicone rubber insulated from the load, with a large capacity, high dynamic multiple, high level of accuracy, maintenance-free, high reliability.
