Description
Technical field:
The utility model belongs to electric power meter survey instrument, is mainly used in current transformer, voltage transformer (VT) field-checking.
Background technology:
Along with the quickening of intelligent grid pace of construction, the quantity of newly-built transformer station gets more and more, and verification task is also along with increase.But, for reducing floor area, high-voltage board is tending towards miniaturization, the installation site of mutual inductor is positioned at again inside cupboard, first can only remove external unit during current transducer check, and people gets into gripping p-wire inside cupboard, the easy like this staff of causing damages, even be stuck in cabinet, not only reduce work efficiency, and bring security risk.
Utility model content:
The purpose of this utility model is in order to more convenient, more safely carries out mutual inductor on site verifying work, meets the demand of field-checking personnel, and devises a kind of rod-type mutual inductor measuring and try out wire clamp, can be easy to use in high-voltage board.
The utility model is achieved through the following technical solutions its utility model object.
A kind of mutual inductor measuring tries out wire clamp, it is characterized in that: primarily of the outer bar of insulation, insulate hollow in the middle part of outer bar, outer bar upper end of insulating is provided with sealing, sealing is provided with round mouth, bar in insulation is inserted with in the outer bar of described insulation, in insulation, on bar, cover has brute spring, outer bar spring bayonet socket is provided with in the outer bar of described insulation, in described insulation, bar is provided with interior bar bayonet socket, described brute spring card top is stuck in below interior bar bayonet socket, lower end withstands on above outer bar spring bayonet socket, in described insulation, bar bottom is connected with clip by terminal, the described body of rod is provided with ramp, clip is provided with ramp equally, two place's ramps are connected by p-wire.
Described terminal is provided with little spring, and little spring is stuck in clamping inner side, and little spring is originally as opening shape.
The outer bar lower end of described insulation is stepped stem, and comparatively upper end is thick for the body of rod diameter of lower end, and internal diameter is also comparatively thick, and clip is collapsible in the body of rod of lower end.
In described insulation, bar upper end is provided with handle.
When operation, the outer bar of the hand-held insulation of staff one, the hand-tight handle of another, puts in mutual inductor place in high-voltage board by insulating bar, touch mutual inductor primary connection bolt, now, pushed away forward by handle, clip stretches out, under the effect of little spring, clip opens and blocks bolt, under the reacting force of brute spring, clip can shrink automatically, blocks bolt securely.
The utility model has the following advantages: structure is simple, easy to use, with low cost, be easy to manufacture, and being convenient to that field staff verifies in high-voltage board is carry out the work better.
Accompanying drawing illustrates:
Accompanying drawing 1 is the utility model structural representation.
Embodiment:
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figure 1, a kind of mutual inductor measuring tries out wire clamp, primarily of the outer bar 1 of insulation, insulate hollow in the middle part of outer bar, outer bar upper end of insulating is provided with sealing 2, sealing is provided with round mouth, wherein be inserted with bar 3 in insulation in the outer bar of insulation, in insulation, on bar, cover has brute spring 4, wherein be provided with outer bar spring bayonet socket 5 in the outer bar of insulation, in insulation wherein, bar is provided with interior bar bayonet socket 6, wherein brute spring card top is stuck in below interior bar bayonet socket, lower end withstands on above outer bar spring bayonet socket, wherein in insulation, bar bottom is connected with clip 8 by terminal 7, the body of rod is wherein provided with ramp 9, clip is provided with ramp equally, two place's ramps are connected by p-wire 10.
Wherein terminal is provided with little spring 11, and little spring is stuck in clamping inner side, and little spring is originally as opening shape.
Wherein the outer bar lower end of insulation is stepped stem, and comparatively upper end is thick for the body of rod diameter of lower end, and internal diameter is also comparatively thick, and clip is collapsible in the body of rod of lower end.
Wherein in insulation, bar upper end is provided with handle 12.
When operation, the outer bar of the hand-held insulation of staff one, the hand-tight handle of another, puts in mutual inductor place in high-voltage board by insulating bar, touch mutual inductor primary connection bolt, now, pushed away forward by handle, clip stretches out, under the effect of little spring, clip opens and blocks bolt, under the reacting force of brute spring, clip can shrink automatically, blocks bolt securely.
More than show and describe ultimate principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
