Abstract
The utility model provides an integrated insulation operating lever of a ground knife switch. The integrated insulation operating lever comprises a nylon insulating rod and a connecting piece, and is characterized in that a hole is arranged in the upper end part of the nylon insulating rod, the nylon insulating rod is connected with a knife switch operating handle through the connecting piece, a pipe hoop and a spring are sequentially arranged at the upper part of the nylon insulating rod, a handle sleeve is arranged at the lower part of the nylon insulating rod, one end of the spring is fixedly arranged on the nylon insulating rod and the other end of the spring is fixedly arranged on the pipe hoop. The integrated insulation operating lever of the ground knife switch has the advantages that the design is exquisite, the universality is high, the manufacturing and repair costs are low, the integrated insulation operating lever is convenient to install and use, the application scope is wide, the embarrassing situation that external parts are required to be used during ground knife switch operation is precluded, and the integrated insulation operating lever is suitable for the reconstruction of all series of outdoor manual ground knife switch operating handles.
Description
Technical field
The utility model relates to a kind of ground connection disconnecting link integral type insulating bar, belongs to mechanical field.
Background technology
Electrical operation personnel is when using outdoor ground connection switch operation, because the limitation of design or site environment, it is very short and small that the operating grip of outdoor ground connection disconnecting link all designs, and must prolong power arm and just can carry out dependent manual operation.The adverse consequences that this type of mode of operation caused is following: prolonging the employed steel pipe of power arm is conductor; When accident occurring, can not auxiliary insulation protection be provided to the operator; Make the operator be exposed to hazardous environment; And all need seek the suitable steel pipe of length thickness before each operation, waste time and energy.
Summary of the invention
In order to address the above problem, the utility model provides a kind of ground connection disconnecting link integral type insulating bar, this instrument deft design; Highly versatile; Manufacturing and maintenance cost are low, easy to install and use, applied range; Must use the difficult situation of exterior part when having stopped the ground connection switch operation, be applicable to the manually transformation of ground connection switch operation handle of outdoor each series.
The utility model adopts following technical scheme:
A kind of ground connection disconnecting link integral type insulating bar; Comprise nylon insulating rod, connector, it is characterized in that: nylon insulating rod upper end is provided with the hole, and the nylon insulating rod links to each other with the switch operation handle through connector; Nylon insulating rod top is provided with pipe collar, spring successively; Nylon insulating rod bottom is provided with taper knob, and spring one end is fixed on the nylon insulating rod, and the other end is fixed on the pipe collar.
Taper knob, pipe collar, spring all are nested with on the nylon insulating rod; The switch operation handle end is provided with groove, and groove is connected with the nylon insulating rod through connector; Insulating bar hangs down under the effect of gravity with annex naturally when not using.When using, insulating bar held up to after the origin operation handle is parallel, spring discharges that potential energy is pushed into the switch operation handle with pipe collar and the fastening effect that entangles firm is played in the insulating bar junction.At this moment just accomplish the process of motive force of growth arm, the operator just can easily accomplish the operation of pull and grounding disconnecting link.Only need pipe collar be pushed towards the spring direction when not using and expose the natural hang that insulating bar can be recovered in the junction.
The ground connection disconnecting link integral type insulating bar that the utility model provides has characteristics such as efficient height, applied range, highly versatile; Alleviate operation personnel burden, reduced external interruption duration, shortened system's abnormal condition damage equipment, improved operating efficiency; The operation behavior of standard operator on duty's pull and grounding disconnecting link; Be to realize effective guarantor's body, the means of protecting electrical network, protecting equipment.
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Description of drawings
Fig. 1 is the structural representation of the utility model.
1 is the hole among the figure, and 2 is pipe collar, and 3 is spring, and 4 is the nylon insulating rod, and 5 is taper knob, and 6 is connector.
Embodiment
Embodiment:
As shown in Figure 1, ground connection disconnecting link integral type insulating bar comprises nylon insulating rod 4, connector 6; Nylon insulating rod 4 upper ends are provided with hole 1; Nylon insulating rod 4 links to each other with the switch operation handle through connector 6, and nylon insulating rod 4 tops are provided with pipe collar 2, spring 3 successively, and nylon insulating rod 4 bottoms are provided with taper knob 5; Spring 3 one ends are fixed on the nylon insulating rod 4, and the other end is fixed on the pipe collar 2.
This instrument utilization insulation well has the prolongation power arm of the nylon rod of fine mechanical strength as former ground connection disconnecting link handle again, and nylon rod and annex thereof do not hang down naturally when using this instrument.In the origin operation handle end groove is set; Be convenient to link to each other with the nylon insulating rod, when this instrument of use, utilize spring automatically pipe collar to be pushed into former ground connection disconnecting link handle and insulated nylon rod junction through connector; Let both entangle firm and fasteningly make it integrated, be convenient to operation.
