Product Overview
External high voltage vacuum circuit breaker (also known as outdoor pole mounted high voltage vacuum circuit breaker) It is mainly used for switching off and closing the load current, overload current and short-circuit current in the distribution network. It is suitable for protection and control in substations and power distribution systems of industrial and mining enterprises. It is more suitable for rural power grids and places with frequent operations. It is especially suitable for the needs of urban and rural power grid transformation. Rated voltage three-phase AC outdoor power distribution equipment.
Structural features Xi'an Tianzheng Electric Power Technology Co., Ltd. supplies Xi'an spot direct sales
The circuit breaker can be equipped with an isolation switch or an anti-inrush delay protector according to user needs.
The three-phase common box type three-phase vacuum arc extinguishing chamber is placed in a metal box and uses insulating materials to insulate between phases and to ground. The insulation performance is reliable and the insulation strength is high.
The circuit breaker can be equipped with a manual spring mechanism or an electric spring mechanism. The electric spring mechanism can be equipped with a wireless remote control.
The circuit breaker can be combined with the corresponding controller to form an automatic recloser, segmenter, etc. according to user requirements to realize distribution network automation.
The intelligent circuit breaker has a secondary reclosing function and the recloser parameters can be adjusted.
The protection parameters with the functions of closing inrush control overcurrent protection and short-circuit quick-break three-stage composite protection can be continuously set by the user.
This circuit breaker (small hydropower type) can be used to monitor line voltage. When overvoltage or undervoltage occurs, the controller automatically opens the circuit breaker. It can be widely used to connect small hydropower branches to the main grid. Network monitoring and automatic fault isolation are implemented at branches.
Lightning arresters can be installed. Lightning arresters can be installed on any side of the incoming and outgoing lines according to user requirements.
The circuit breaker can be equipped with a measuring or metering transformer.

Use environmental conditions
Upper and lower limits of ambient temperature.
Altitude
Wind pressure (equivalent to wind speed/)
Air pollution level
No frequent severe Vibration
Series switch features
Variable ratio/current transformer can be installed according to user needs. The outer insulation adopts high-voltage silicone rubber sleeve and the inner insulation is composite insulation
Built-in multi-tap current transformer can be used for over-current protection
Double-winding current transformer can be used for protection and measurement
If a voltage transformer is installed, it will automatically reclose. The automatic segmentation controller of the controller can realize the automation of power distribution protection and the four-remote (telemetry, remote signaling, remote control and remote adjustment) functions. A composite controller is installed (eliminating closing inrush current).
An isolation switch can be installed
