Permanent magnet outdoor vacuum circuit breaker is the Company's consolidated foreign advanced technology, public gambling house long, with a new design concept, the use of high-tech means, the latest development of a new generation of column vacuum circuit breakers.
General:
The product can be used as the main transformer 10kV Substation35kV switch outlet, but also as a distribution network of column switch, and this combined with the companv's controller can facilitate the realization of control. protection.measurement. communication, is to achieve preferred equipment distribution network automation and miniaturization substation.
Service Environment
Working temperature: -40℃~+40℃
Operating humidity:0-95%
The working environment of solar radiation: ≤1.1kW/m
The wind speed does not exceed 35m/s (equivalent to 700pa on the cylindrical surface)
Pollution Level: IV grade
Ice thickNess:≤10mm

Key Feature
Permanent magnet mechanism, the use of a large number of components, the closing power is greatly reduced, stable and reliable, no regular maintenance.
Imported outdoor epoxy resin is used as external insulation material.
Light weight, more than 15 years of life, good weather resistance, no oil, no SF6, in line with environmental requirements.
The operation time is short, the fault can be cut off quickly, and the protection is convenient and flexible.
External PT is selected as the power supply, and electric operation can be achieved without external power supply.
The special remote control can be used to achieve remote control operation, and the power supply operation can be stopped without the rod.
The integrated design of the high-voltage isolation switch makes the compact installation and maintenance very convenient.
