It is mainly used for overload and short circuit protection within the circuit of AC 50/60 Hz, rated voltage of single pole up to
230V, two, three or four poles up to 400V. It can also be used for an infrequent switch-over of the circuit and illumination under normal conditions.
Enclousers & Breakers
SH201 1 Pole low voltage electrical circuit breaker is mainly used in AC50/60Hz single pole 230V or two,three,four pole 400V voltage for overload and short-circuit protection as well as for infrequent on-and-off switching electric equipment and lighting circuit under normal conditional the product is suitable for industry,business,building,residence,etc. It's conformity with GB10963, IEC60898 standards.
The cable design conforms to the requirements of national standard GB/T12706-2008 and IEC60502 recommended by international Electrotechnical Commission. The normal operating temperature of the conductor of polyvinyl and XLPE insulated cable is 70â?? and 90â?? ,Xlpe cable not only has excellent electrical performance, high working temperature, large transmission capacity, but also has the advantages of simple structure, small outer diameter, light weight, easy installation and use, and unrestricted laying drop. It is widely used in industrial and mining enterprises and urban power grid.
WSD-ZW32-24D Outdoor AC high voltage vacuum circuit breaker (hereinafter referred to as circuit breaker) is a rated voltage of 24 KV, 50 HZ three-phase AC outdoor distribution equipment.The utility model has the advantages of stable and reliable interruption performance, no danger of combustion and explosion, maintenance-free, small size, light weight and long service life.It is mainly used for breaking and closing the load current, overload current and short circuit current in power system.It is suitable for protection and control in power distribution systems of substations and industrial and mining enterprises, and more suitable for rural power grids and frequently operated places. This product meets GB1984-2003 "High Voltage AC Circuit Breakers" and DL/T402-2007 "Technical Conditions for Order of High Voltage AC Circuit Breakers" and DL/T403-2000 "Technical Conditions for Order of 12 kV~40.5 kV High Voltage Vacuum Circuit Breakers" and other technical standards.
CHARACTERISTICS 1. The vacuum arc extinguishing chamber uses longitudinal magnetic field arc extinguishing technology, which has the characteristics of long electric life and high reliability. 2. The imported silicone rubber/epoxy resin for outdoor use and the present APG vacuum injection technology are adopted. 3. Anti-ultraviolet, moistureproof, anti-corrosion, with the advantages of preventing surface discharge, good hydrophobicity and high mechanical strength. 4. Using simple and reliable spring operating mechanism, it has the advantages of small size and light weight. 5. high voltage vacuum circuit breaker can be equipped with isolation switch and three-phase linkage. It has visible breaks when the isolation switch is switched off. It also has anti-mistake interlock between the isolation switch and the circuit breaker body. It can be equipped with arrester strut insulators. Operational sequence When operating the disconnector, the first step is to confirm that the circuit breaker should be in the open state. Use the insulated tie rod hook to fasten the closing pull ring or the opening pull ring of the operating handle of the isolation closure, pull down slightly, drive the spindle to rotate, open or close the isolation switch. When the spindle rotates the dead point position of the compression spring, a certain tension is maintained so that the blade can be reliably closed or opened to a safe isolation position.
Zn68-12 series of indoor high voltage vacuum circuit breaker is three phase a.C.50(60) hz indoor high voltage distribution equipment with 12kv rated voltage and below. This kind of circuit breaker is characterized by simple construction, strong breaking capability, long life with complete operating functions and convenient maintenance.
