Abstract
The utility model discloses a kind of duck-beak type pressure-wire connection device, comprise head cylinder, screw thread, pin, copper plate, elastic threads, connection bracket, afterbody duckbilled is made up of afterbody duckbilled the first half and afterbody duckbilled the latter half; Head cylinder, inserts for adjusting instrument pressure-wire; Screw thread, for connection header cylinder and afterbody duckbilled; Pin, in afterbody duckbilled upper end, totally two, for fixing copper plate, makes elastic threads tighten, thus afterbody duckbilled is closely clipped up and down; Copper plate, in afterbody duckbilled upper end, fixes two elastic threads below, and sidewards, elastic threads relaxes general state copper plate, and when needing to step up, namely rotate copper plate, elastic threads is tightened; Elastic threads, upper end is fixed on below copper plate, through afterbody duckbilled; Connection bracket, at head cylinder edge, for connecting head cylinder between phase and phase, makes alternate separately fixing.The beneficial effects of the utility model are: the situation of voltage generation two-phase and even three-phase touching short circuit when effectively prevent protection test.
Description
Technical field
Pressure-wire connection device when the utility model relates to the test of a kind of transforming plant protecting, voltage lead-in on the pressure-wire that connects adjusting instrument and terminal board, particularly relates to a kind of duck-beak type pressure-wire connection device.
Background technology
Current on-the-spot actual employing usually 3 crocodile clips, the pressure-wire of a slotting adjusting instrument, another head-clamp terminal board voltage lead.Have the following disadvantages: 1, insulating tape winding in chuck place is unreliable, easily alternate touching short circuit occurs; 2, because 3 crocodile clips are not fixed, can move freely, when outside is mobile, easily there is phase fault in crocodile clip afterbody metallic member; 3, crocodile clip to a certain degree damages terminal board place voltage the end of a thread.
Utility model content
The purpose of this utility model overcomes deficiency of the prior art, and provide a kind of rational in infrastructure, safety and stability, during solving device protection test, the duck-beak type pressure-wire connection device of the problem of phase fault easily occurs voltage lead-in.
This duck-beak type pressure-wire connection device, comprises head cylinder, screw thread, pin, copper plate, elastic threads, connection bracket, and afterbody duckbilled is made up of afterbody duckbilled the first half and afterbody duckbilled the latter half; Head cylinder, inserts for adjusting instrument pressure-wire; Screw thread, for connection header cylinder and afterbody duckbilled; Pin, in afterbody duckbilled upper end, totally two, for fixing copper plate, makes elastic threads tighten, thus afterbody duckbilled is closely clipped up and down; Copper plate, in afterbody duckbilled upper end, fixes two elastic threads below, and sidewards, elastic threads relaxes general state copper plate, and when needing to step up, namely rotate copper plate, elastic threads is tightened; Elastic threads, upper end is fixed on below copper plate, and through afterbody duckbilled, duckbilled lower surface is fixed in lower end; Connection bracket, at head cylinder edge, for connecting head cylinder between phase and phase, makes alternate separately fixing; Connecting portion by taper between afterbody duckbilled with head cylinder is connected.
The beneficial effects of the utility model are: the situation of voltage generation two-phase and even three-phase touching short circuit when the utility model duck-beak type pressure-wire connector effectively prevent protection test.

Description of reference numerals: head cylinder 1, screw thread 2, pin 3, copper plate 4, elastic threads 5, connection bracket 6, afterbody duckbilled the first half 7, afterbody duckbilled the latter half 8, connecting portion 9.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.Although the utility model will be described in conjunction with preferred embodiment, should know, not represent the utility model restriction in the described embodiment.On the contrary, the utility model will contain can be included in attached claims limit scope of the present utility model in alternative, modified model and equivalent.
Shown in Fig. 3, this duck-beak type pressure-wire connection device of the present embodiment, comprise head cylinder 1, screw thread 2, pin 3, copper plate 4, elastic threads 5, connection bracket 6, afterbody duckbilled is made up of afterbody duckbilled the first half 7 and afterbody duckbilled the latter half 8; Head cylinder 1, inserts for adjusting instrument pressure-wire; Screw thread 2, for connection header cylinder 1 and afterbody duckbilled; Pin 3, in afterbody duckbilled upper end, totally two, for fixing copper plate 4, makes elastic threads 5 tighten, thus afterbody duckbilled is closely clipped up and down; Copper plate 4, in afterbody duckbilled upper end, fixes two elastic threads 5 below, and sidewards, elastic threads relaxes general state copper plate 4, and when needing to step up, namely rotate copper plate 4, elastic threads 5 is tightened; Elastic threads 5, upper end is fixed on below copper plate, and through afterbody duckbilled, duckbilled lower surface is fixed in lower end; Connection bracket 6, at head cylinder 1 edge, for connecting head cylinder 1 between phase and phase, makes alternate separately fixing; Connecting portion 9 by taper between afterbody duckbilled with head cylinder 1 is connected.
Head cylinder place inserts the pressure-wire of adjusting instrument, and the voltage the end of a thread on the first inserted terminals row of afterbody duckbilled, rear rotation copper plate steps up voltage the end of a thread, copper plate is fixed on pin place, realizes external voltage line and is reliably connected with terminal board pressure-wire.
By connection bracket 6, can reach between A, B, C, N phase and reliably separate, avoid the effect of the alternate touching short circuit of head cylinder 1 place voltage; By copper plate 4, elastic threads 5, afterbody duckbilled the first half 7 and afterbody duckbilled the latter half 8, inserted by the voltage the end of a thread at terminal board place in the middle of duckbilled, rotate copper plate 4, clamping the end of a thread, convenient and reliable clamping the end of a thread, does not damage the end of a thread on the one hand; Avoid the alternate touching short circuit of afterbody on the other hand.
