ZW8-12G intelligent circuit breaker

<> (1) Model ZW8-12GZ "Z represents the vacuum load" W is the representative for outdoor use, 12 is representative of the voltage, Z represents the intelligent demarcation, G is with isolation (2) Products; manual operation of the circuit breaker and Electric operation with voltage transformers with stainless steel. (3) 630A-1250A is representative of the current, (20KVA-25KVA-31.5KVA is representative of the short-circuit current is interrupted.) (4) telephone customer orders;. 0577-62708571 &&&&&& Granville (5) Fax; 0577-62708570. (6) 1-2 days of delivery time, the goods are starting from Zhejiang province, (7) household customer orders to pay attention to the following points. The first is how much voltage, current, how much, whether the operation of electric and manual operation voltage 48V-110V-220V (8) If you have not read, the customer can call the company telephone consultation. 24-hour telephone; 0577-62708571 (9) product if there are problems, the province 48 hours to reach the province 24 hours to reach the maintenance, customers can rest assured that the use of vacuum circuit breakers ZW8-12G plateau breaker combination with isolation, rated voltage 12KV three-phase AC 50HZ high voltage outdoor switchgear, built-in voltage 12KV into a 220V operating voltage, CT for the built-in current transformer, mainly used to breaking off load current co rural network, City and small power system, overload current, short-circuit current. The overall structure of the product box for three-phase, three-phase vacuum interrupter in a metal box, use SMC insulation and white insulation and ground insulation, reliable performance, high dielectric strength. The product can also be coincident with the controller with easily accessible power supply suitable for the occasion, PT type coincides with the controller with no power applied to the occasion, intelligent circuit breaker for the power supply and the ring-and-spoke network power supply system, the help system to eliminate transient faults Automatic restoration of electricity, but also permanent fault isolation to achieve distribution automation. Smart breaker with 1 to 3 times reclosing function, and can overlap tuning parameters; intelligent circuit breaker with closing surge control, overcurrent and short circuit protection quick break three sections of composite functions and parameters can be continuous tuning; intelligent circuit breaker with a small current grounding protection, and parameters can be continuous tuning; intelligent circuit breaker either wired remote control, wireless remote control can also be in the bar. For AC 50Hz, voltage three-phase power system 10 ~ 12kV as breaking, closing load current purposes, it has overload and short circuit protection, quick-break protection, definite time delay protection, automatic reclosing function, but also According to user needs arrester fitted or isolating switch (ie, a combination of circuit breakers and disconnectors, hereinafter referred to as "a combination of intelligent circuit breaker"), etc. The self-powered intelligent circuit breaker, the nearest remote control, with CT, PT interface, which can meet the requirements of circuit breaker interrupter device telemetry, it can bring a load circuit breaker operation, not only to operate the load current, but also to operate fault (short circuit) current; breaker has a good package, it is simple to observe breaker , can not directly determine whether it is in the closed or open position. Disconnectors no interrupter device, although the rules of order that can be operated in the load current is less than 5A occasions, but it does not belong with the overall load operation; but the simple isolation switch structure, from the appearance can see at a glance the status of its operating, maintenance and when clear break point. In use, the circuit breaker referred to "switch", disconnector referred to as "knife" In use, the two often used in combination. ---- Conditions: * no more than 4000 meters above sea level; * * maximum ambient air temperature is less than the lower limit of 40 ℃ -40 ℃; * daily average relative humidity less than 95%, the monthly average of less than 90%; * No recurring severe vibration Technical parameters: Rated voltage 12KV; * rated current 630-1250A; rated active load breaking current 630-1250A; * Rated breaking current loop 630-1250A; 5% rated active load breaking current 62.5A; * rated cable charging current 25A; 1 minute power frequency withstand voltage: vacuum fracture 48KV, white / relative to 42KV.
