Abstract
The utility model discloses an indoor high-voltage vacuum circuit breaker insulation pull rod, which comprises a connecting rod (1), a nut (2) and a pull rod insulator (4). A pressure spring (3) is sealed inside the pull rod insulator (4), a connection portion of the pull rod insulator (4) connected with an arc extinguish chamber is an inner tapping hole, a connection portion of the pull rod insulator (4) connected with a large crank arm of a circuit breaker is a lead screw, and the pull rod insulator (4) is formed by pressing synthetic nylon. The indoor high-voltage vacuum circuit breaker insulation pull rod saves raw materials, is low in cost, and is time-saving and labor-saving during assembly debugging.
Description
Technical field
The utility model relates to the indoor AC high voltage vacuum breaker in a kind of electrical power distribution system, and is special relevant with the insulated tension pole of indoor high-voltage vacuum circuit breaker.
Background technology
Insulated tension pole is the critical component of vacuum circuit-breaker, is determining the speed of cut-offfing and the connecting-disconnecting function of vacuum circuit-breaker.The insulated tension pole of 10kV and the indoor AC high voltage vacuum breaker of following electric pressure is made up of link insulator, connecting rod, nut and dish spring four parts at present, and dish spring and connecting rod bottom are encapsulated in the link insulator by nut.As shown in Figure 1.In existing assembly technology, at first to be fixed on insulated tension pole on the arc control device, the integral body insulating cylinder of packing into then, mechanism provides power by insulated tension pole for arc control device, but insulated tension pole is to realize by a pin with being connected of mechanism, so cumbersome in the debugging of circuit breaker being carried out mechanical property.So this kind structure not only assembly technology is loaded down with trivial details, and cost is also than higher.Sometimes owing to the defective electrical characteristic and the mechanical property that has influence on circuit breaker of part dish spring, may cause circuit breaker can not normally cut-off short circuit current under the serious situation, thereby cause very big economy and social loss simultaneously.We must take off insulating cylinder just and can debug from circuit breaker frame fully during debugging, waste time and energy.
The utility model content
The utility model is to provide that a kind of cost is low, assembling and setting indoor high-voltage vacuum circuit breaker insulated tension pole easily.
The insulated tension pole of the utility model indoor high-voltage vacuum circuit breaker comprises connecting rod, nut and link insulator, it is characterized in that, be packaged with stage clip in the link insulator, the connecting portion of link insulator and arc control device is the internal tapping hole, the junction of link insulator and the big connecting lever of circuit breaker is a screw mandrel, and link insulator is formed by the synthetic nylon compacting with high-insulativity and good mechanical characteristic.
The insulated tension pole of the indoor high-voltage vacuum circuit breaker that the utility model provides is saved raw material, and cost is low, and assembling and setting is time saving and energy saving.
Description of drawings
Fig. 1 is the structural representation of existing indoor high-voltage vacuum circuit breaker insulated tension pole;
Fig. 2 is the structural representation of an embodiment of the utility model indoor high-voltage vacuum circuit breaker insulated tension pole.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, connecting rod 2, nut 3, stage clip 4, link insulator 5, connecting rod 6, dish spring 7, link insulator
As shown in Figure 2, the indoor AC high voltage vacuum breaker insulated tension pole of the utility model comprises connecting rod 1, nut 2 and link insulator 4, it is characterized in that being packaged with in the link insulator 4 stage clip 3, link insulator 4 is the internal tapping hole with the connecting portion of arc control device, link insulator 4 is a screw mandrel with the junction of the big connecting lever of circuit breaker, and link insulator 4 is formed by the synthetic nylon compacting with high-insulativity and good mechanical characteristic.
Use stage clip 3, insulated tension pole is easy to assembly, save time, and is convenient and accurate in Installation and Debugging.This structure can solve the assembly problem and the cost problem of insulated tension pole effectively.In being connected of link insulator 4 and arc control device, use the internal tapping hole, saved assembling and debug time, also make link insulator 4 and being connected of arc control device more reliable fastening, make it have better electric conductivity.Link insulator 4 uses screw mandrel with the junction of the big connecting lever of circuit breaker, only needs a pin to be fixed on the big connecting lever of breaker mechanism in assembling process, utilize two nuts to tighten pin then, has realized circuit breaker main part and mechanism being connected partly.In the process of debugging, only need regulate the debugging that just can realize to two nuts to breaker mechanic property, more help workman's equipment and debugging.
