ZW32-12M Series Outdoor Column Intelligent Prepaid Vacuum Circuit Breaker

Overview:

ZW32-12M outdoor permanent magnet high-voltage AC vacuum circuit breaker adopts the principle of vacuum arc extinguishing, permanent magnet operating mechanism, and integrates microprocessing technology, modern network communication technology and switch manufacturing materials. Outdoor power distribution equipment with rated voltage of 12kV and 50Hz three-phase AC. The product is widely used as a disconnect or contact switch in the urban power grid, or in the rural power distribution system.

The outgoing switch of outdoor substation can effectively complete the work of the traditional recloser, dividing and closing the load current and short-circuit current.

Normal Conditions of Use:

◇ Ambient air temperature: -40°C~+55°C, daily temperature difference: daily variation 25K;

◇ Altitude: no more than 2000m;

◇ Wind speed: no more than 35m/s;

◇ Pollution Level: IV.;

◇ Installation site: no flammable, explosion hazard, chemical corrosion place;

◇ The seismic intensity does not exceed 8 degrees;

Key features:

The vacuum circuit breaker adopts a permanent magnet operating mechanism, which forms a good match with the vacuum interrupter, and the closing action is stable and reliable, and the service life is long; At the same time, the composite solid insulation structure is adopted, and the vacuum interrupter, the dominant electrical circuit, and the insulation support are organically combined into an integrated solid sealing column, which completely solves the contradiction between the miniaturization of the vacuum interrupter and the external insulation requirements, and the whole product is reasonably designed and compact, the box is sealed, there is no condensation inside, there is no rust in the parts, and the reliability of the switch is greatly improved. The vacuum circuit breaker applies a number of technologies, which makes it have many advantages: no SF6 gas, no oil, less environmental impact, and is conducive to environmental protection; The unit is small in size, light in weight, and easy to install on the column; The intelligent control unit is compact and can be simply installed under the column, or it can be equipped with an optional wireless remote control to control the opening and closing of the switch within a range of 30m; It is convenient for local operation and remote control of urban and rural power grids.
