Pole mounting base is connected at the top of device ontology, and four corners of pole mounting base bottom offer mounting hole, it is described
The bottom end of pole mounting base offers on/off switch indicating window, and the top installation of pole mounting base is there are three pole, and three
The pole is in one line in the horizontal direction, and inlet wire column is respectively connected at the top of three poles, an institute of middle position
The back side for stating pole is fixed with outlet column, and the back side of other two pole is mounted on current transformer, the Current Mutual Inductance
There are two device is arranged altogether, the outlet column is located between two current transformers.
Preferably, wiring hole is provided on the inlet wire column.
Preferably, hanging ring is provided in the pole mounting base.
Preferably, parachute skirt is provided on the pole.
Preferably, rubber antiskid set is provided on the sub-switching operation handle and energy accumulation handle.
Compared with prior art, the utility model has the beneficial effects that
(1) controller and breaker body are used cooperatively by the utility model, by breaker body to 10kV route into
Row disjunction and close control, detected the failure of 10kV route by controller, and control breaker body realize it is automatic, directly
User's phase fault and automatic reclosing in boundary are cut off, realizes and automatically, directly cuts off segmentation and user's single-phase earthing in boundary
Failure, realize automatism isolation user side accident, substantially increase the selectivity of failure, avoid segmentation and sole user failure and
Protection cooperation is improper and involves whole line outage, can be in fast quick-recovery circle at 10kV facet and caused by user's transient fault
Have a power failure, shortens the power supply recovered from failure time;
(2) the utility model is provided with power supply PT, and power supply PT is with big storage energy, reliable for operation and complete non-maintaining
Standby energy storage power system can still provide for breaker body disjunction behaviour in the case where 10kV line fault even route decompression
To make, can be directly mounted on electric pole, degree of protection is high, has and exempts to protect performance for a long time, it is also equipped with remote control switching on and off function on the spot,
Convenient for line maintenance maintenance.
