Come more, if using sulfur hexafluoride gas-insulating, electric cost will be greatly increased.
The content of the invention
To solve the above problems, this utility model provides a kind of utilization air insulation, low cost, the outdoor high-voltage of small volume
Vacuum circuit breaker ring main unit.
The technical solution of the utility model is：A kind of outdoor high-voltage vacuum breaker ring main unit, including：Cabinet, in cabinet
It is provided with spring energy-storage operating mechanism, earthed switch and the vacuum circuit breaker with vacuum interrupter；Vacuum interrupter both sides
Ohm sleeve pipe for bus turnover is provided with, ohm is telescopic joint copper bar；The phase spacing of vacuum circuit breaker is 250mm；Connect
Ground switch is connected with vacuum circuit breaker, and vacuum circuit breaker is connected with spring energy-storage operating mechanism by insulated tension pole.
Further, the spring energy-storage operating mechanism includes spring mechanism, energy storage device, energy accumulation handle；The spring
Mechanism is arranged on bottom of cabinet bulk, and the energy storage device, energy accumulation handle are connected with spring mechanism respectively, and the energy accumulation handle is arranged on
On cabinet.
Further, on cabinet, correspondence energy accumulation handle position arranges division mark.
Further, the spring energy-storage operating mechanism also includes divide-shut brake display lamp and energy storage display lamp, the division
Lock display lamp, energy storage display lamp are separately positioned on cabinet.
Further, link gear is provided between the earthed switch and vacuum circuit breaker.
Further, solid protective shell is set at the top of cabinet.
The outdoor high-voltage vacuum breaker ring main unit that this utility model is provided, vacuum circuit breaker phase spacing is set to
250mm, using air insulation, inventor Jing test of many times confirms that the pattern can replace sulfur hexafluoride gas completely, both environmental protection
Reduces cost, and ring main unit small volume again, convenient use.

With stronger insulating properties, personal security can be effectively protected when operator install.Ohm sleeve pipe 4 is connected with copper bar
11, its safe distance can be increased.The phase spacing a of vacuum circuit breaker is that 250mm, i.e. three-phase bus access ring main unit, three-phase
The distance between bus is 250mm.
Spring energy-storage operating mechanism includes spring mechanism 5, energy storage device 7, energy accumulation handle 10.Spring mechanism 5 is arranged on cabinet
2 bottom of body, energy storage device 7, energy accumulation handle 10 are connected with spring mechanism 5 respectively.Energy storage device 75 stored energy of spring mechanism,
Meeting with an accidet or effectively can make a response rapidly during failure, and in the case of whole device is powered, energy storage device 7
Energy storage is automatic energy storage.Energy accumulation handle 10 is arranged on cabinet 2.On cabinet 2,10 position of correspondence energy accumulation handle arranges division mark,
To facilitate divide-shut brake.Spring energy-storage operating mechanism also includes divide-shut brake display lamp 8 and energy storage display lamp 9, divide-shut brake display lamp 8,
Energy storage display lamp 9 is separately positioned on cabinet 2, and divide-shut brake display lamp 8, energy storage display lamp 9 are respectively used to indicate opening and closing state
And energy storage state.
Disclosed above is only preferred implementation of the present utility model, but this utility model is not limited to this, any
What those skilled in the art can think does not have creative change, and is made under the premise of without departing from this utility model principle
Some improvements and modifications, should all fall in protection domain of the present utility model.
