Description
Technical field
The utility model relates to high-tension distribution equipment, particularly a kind of SF
6Insulation vacuum dividing switch cubicle.
Background technology
Common high voltage vacuum switchgear cabinet generally comprises elements such as being installed in the interior vacuum circuit-breaker of cabinet, isolating switch, current transformer, voltage transformer, existing vacuum switch cabinet great majority adopt air insulation, the cabinet molded dimension is all bigger, general vacuum circuit-breaker is installed in the interior different bins of cabinet independently of one another with isolating switch, connects with conductor during combination again, and electrified body is exposed, be subjected to the erosion of air, dust, easily cause the corrosion of electrified body, reduced the class of insulation, the life-span is short.And the existing SF that uses
6As the switch cubicle of insulation and arc-extinguishing medium, its on-load switch contact is in open state, and the electric elements in easy pollution of the electric arc that produces in cut-offfing and the damage cabinet influence switch complete machine performance; In addition, because SF
6Gas is also being born the task of arc extinguishing, needs higher air pressure, to the seal request height of switch bin, thereby has improved the device fabrication cost; And its transmission mechanism is comparatively complicated, and moving component is many, and failure rate is higher.
Summary of the invention
Technical problem to be solved in the utility model is, provide a kind of simple in structure, volume is little, stable performance, long service life, make and the lower SF of maintenance cost
6Insulation vacuum dividing switch cubicle.
SF of the present utility model
6Insulation vacuum dividing switch cubicle includes a cabinet, and the upper back in cabinet is provided with a hermetic SF of being filled with
6The gas tank of gas, the vacuum circuit-breaker that is positioned at the middle part is installed in the gas tank, is positioned at the isolating switch of vacuum circuit-breaker top and is positioned at the earthed switch of bottom half, main bus bar row be connected with static contact isolation switch, the outlet sleeve pipe is installed on the front panel of gas tank bottom, and current transformer is sleeved on the outlet sleeve pipe; Front upper part in cabinet is equipped with the spring operating mechanism of isolator operating mechanism and vacuum circuit-breaker; Bottom in cabinet is equipped with voltage transformer.
The inside and outside gas pressure difference of described gas tank is zero.
Each phase arc control device assembly of described vacuum circuit-breaker is housed in respectively in the insulation booth.
The utility model has the advantages that: all electrification in high voltage parts all are sealed in SF in the cabinet
6In the gas tank, not affected by environment, really realize non-maintaining; Adopt vacuum extinction, SF
6Gas-insulated, it is so volume is little, and break performance is good, reliability is high, and electric arc does not expose in cut-offfing, and can not pollute and damage the electric elements in the cabinet; Because SF
6Gas does not participate in arc extinguishing, need not higher pressure, can adopt the pressure suitable with external atmospheric pressure, has reduced sealing difficulty, has reduced manufacturing cost yet; Adopt insulation booth that each phase arc control device assembly is isolated, strengthened creepage distance, improved the class of insulation.
