Abstract
The utility model relates to a breaker and provides the direct-acting sealing structure of a high-voltage sulfur hexafluoride circuit breaker, wherein an operating lever is arranged in the central hole of a sealing base. The central hole of the sealing base is provided with two rubber ring slots and a sealing hole. The sealing hole is positioned between the two rubber ring slots. Each rubber ring slot is internally provided with special-shaped sealing ring and gaskets. The sealing hole is internally filled with low-temperature No.2 grease. According to the technical scheme of the utility model, the direct-acting sealing structure of the high-voltage sulfur hexafluoride circuit breaker is simple in structure and the sealing effect is realized by means of the sealing ring. The operating lever is arranged in the central hole of the sealing base. The central hole of the sealing base is provided with two rubber ring slots and one sealing hole. Each rubber ring slot is internally provided with one special-shaped sealing ring and two polytetrafluoroethylene gaskets. The sealing hole is full of low-temperature No.2 grease. In this way, the above sealing structure is different from a conventional complicated structure in the prior art, wherein according to the complicated structure, the sealing hole of a combined sealing gasket made of different materials is internally provided with a spring and a sealing gasket is arranged to abut against an operating lever under the pressure force of the spring. Therefore, the friction force is reduced and the operating power is lowered. The above direct-acting sealing structure passes the test on the braking system. By means of the structure, the design requirement on the sealing property of products can be completely met.
Description
Technical field:
The utility model relates to circuit breaker.
Background technology:
Separating brake and the combined floodgate of Direct Action Type sealing circuit breaker, be action bars under the actuating of spring mechanism, do linear reciprocating motion and complete.The upper end of action bars is contained in the airtight sulfur hexafluoride gas of arc-extinguishing chamber of circuit breaker, lower end exposes in air, in order to prevent the leakage of sulfur hexafluoride gas, on circuit breaker, adopt sealing mechanism, guarantee that the motion of action bars is smooth and easy simultaneously, do not affect separating brake and the closing speed of circuit breaker, conventional circuit breaker adopts rotating seal mostly, this complex structure, and machine driving link is many, produce assembling more difficult, sealing effectiveness is not good.For these reasons, direct-acting sealing mechanism is comparatively reasonable at present, as Chinese patent, the combination sealing packing ring of spring and unlike material is housed in closed hole, by spring pressure, seal washer is contacted with action bars, although improved sealing property, it is cumbersome that its structure still shows slightly, frictional force is large, has reduced operating work.
Summary of the invention:
The technical scheme that the utility model adopted is for achieving the above object: the direct-acting sealing mechanism of high pressure sulfur hexafluoride breaker, simple in structure, easy for installation, sealing effectiveness is good.
The technical scheme that the utility model adopted is for achieving the above object: the direct-acting sealing mechanism of high pressure sulfur hexafluoride breaker, action bars is contained in seal receptacle centre bore, seal receptacle centre bore is with twice aprons slot and a closed hole, closed hole is between twice aprons slot, it is T shape sealing ring and packing ring that a section is housed in each aprons slot, fills up 2 in closed hole
#low temperature grease.
Described section is that the perpendicular edge sealed bottom face of T shape sealing ring adopts arc surface.
Described packing ring adopts two polytetrafluoroethylene gaskets, and it is T shape sealing ring perpendicular edge both sides that packing ring is placed in respectively section.
The utility model is simple in structure, adopts sealing ring sealing, and action bars is contained in seal receptacle centre bore, and seal receptacle centre bore, with two aprons slots and a closed hole, is equipped with a fixing ring and two polytetrafluoroethylene gaskets in each groove, fill up 2 in closed hole
#low temperature grease, had changed in the past the cumbersome structure of " the combination sealing packing ring of spring and unlike material is housed in closed hole, by spring pressure, seal washer is contacted with action bars ", had reduced frictional force, had reduced operating work.This translation seal system is examined by type approval test, reaches the Seal Design requirement of product completely.
Accompanying drawing explanation:
Fig. 1 is the utility model structural representation.
Fig. 2 is I enlarged drawing in Fig. 1.
In figure: 1 action bars; 2 seal receptacles; 3 aprons slots; 4 closed holes; 5 packing rings; 6 fixing rings.
Embodiment:
The direct-acting sealing mechanism of high pressure sulfur hexafluoride breaker as shown in Figure 1, action bars 1 is contained in seal receptacle centre bore, seal receptacle 2 centre bores are with twice aprons slot 3 and a closed hole 4, closed hole is between twice aprons slot, a fixing ring 6 and packing ring 5 are housed in each aprons slot, as shown in Figure 2, fixing ring section is T shape, fixing ring perpendicular edge sealed bottom face adopts arc surface, packing ring adopts two polytetrafluoroethylene gaskets, and packing ring is placed in respectively fixing ring perpendicular edge both sides; In closed hole, fill up low temperature 2
#lubricating grease.
