Abstract
The invention discloses a front clamp of a decomposition type ground potential replacement clamp. The front clamp is a wing type clamp, wherein square opening grooves are formed at two ends of two wings of the wing type clamp; positioning through holes, which are communicated with each other, are formed in upper and lower groove edges of the opening grooves of the two wings of the wing type clamp; a locking pin is arranged on the wing type clamp; the locking pin is connected to the positioning through holes in the two wings of the wing type clamp in a movable manner; the locking pin is positioned at the groove edges of the opening grooves of the two wings by using a positioning piece; a through hole into which the locking pin can be inserted is formed in an insulating pulling plate; and when the insulating pulling plate is inserted into the opening grooves of the two wings of the front clamp, the positioning piece is pulled out, the locking pin freely falls down under the action of self gravity, the locking motion of the locking pin is finished by adjusting the position of the insulating pulling plate, and the insulating pulling plate and the front clamp are locked. The front clamp has the advantages that: by using a decomposition installation method, the clamp is detachable; the front clamp can flexibly pass through a double-split conductor, and has a reliable function of a locking device; and the weight of the clamp during installation is reduced.
Description
Technical field
The present invention relates to a kind of breakdown earth potential and change the preceding card that jig, particularly breakdown earth potential are changed jig.
Background technology
Existing earth potential is changed jig, because the rerum natura of jig structure has determined jig can only adopt integral installation, after just in advance the whole series card peace being assembled; Together jig is lifted on the insulator string by a plurality of electricians and install, this mounting means is because a whole set of jig overall weight is big; Also need jig be lifted to higher position simultaneously installs; Therefore installation difficulty is big, and operating personnel's labour intensity is big, the dangerous height of operation; Inefficiency, and can't accomplish the charged installation of wiring on the same tower circuit.
Summary of the invention
The objective of the invention is to overcome the weak point of prior art, overcome jig a difficult problem is installed and provide a kind of, the breakdown earth potential that reduces labour intensity changes the preceding card of jig.
A kind of breakdown earth potential is changed the preceding card of jig, and described preceding card is wing card, and its structural feature is: the both ends of wing card two flanks are square open slot; The plane extension direction of the opening direction of described open slot and wing card two flanks parallels; On two trough rims up and down of wing card two flank open slots, offer the positioning through hole of mutual perforation, on wing card, also be provided with a lockweight, this lockweight is movably connected on the positioning through hole place on wing card two flanks; Before before the insulation arm-tie snaps in this, blocking two flank open slots; Described lockweight utilizes keeper to be located trough rim place on two flank open slots, and the insulation arm-tie is provided with the through hole that can insert lockweight, when before the insulation arm-tie inserts, blocking two flank open slots; Pull out keeper; Then lockweight freely falls under the effect of deadweight, makes lockweight accomplish the action that latches through the position of adjusting insulation board, pins insulation arm-tie and preceding card.
The preceding card of this structure; In use; Owing to have self-locking gear; Therefore can realize installing with the decomposition of back card, insulation arm-tie, when mounted, preceding card can independently be installed in assigned address or pass through the lockweight that is installed in down behind the Square wire through card before the insulating bar operation and preceding card is stuck in lead regulates to win in succession and go up the completion locking.Its concrete operations are will insulate arm-tie along the entering of the open slot on preceding card two flanks by an electrician through action bars; Operation insulation arm-tie is adjusted to the length that needs; No. two the electrician utilizes insulating bar to make lockweight freely fall the keeper on preceding card two flanks, and adjustment insulation arm-tie to lockweight is accomplished locking.Installation with insulation arm-tie about the method completion.The back card then is installed again.Therefore adopting preceding card of the present invention to overcome needs to adopt the various shortcomings that integral installation brought, and greatly reduces labor intensity of operating personnel.
The mode that lockweight is movably connected on wing card two flanks is: along lockweight axially offer one section logical heart slotted hole, in logical heart slotted hole, be provided with and can lockweight be stuck in the latch on the wing card.
During use, utilize latch to pass passing through on the lockweight, then lockweight is filled in the through hole of trough rim on wing card two flanks, and utilized latch to be stuck on the wing card.
Described flexible connection can also be that flexible things such as direct sharp rope hang on lockweight on wing card two flanks.
On blocking before described keeper is movably connected on.
The flexible connection of described keeper or on the card before hanging on, or for blocking before being articulated in.
Described keeper or be spring leaf, or be common blocks etc.
In sum, the present invention compares the following advantage of prior art:
Preceding card that breakdown earth potential of the present invention is changed jig has cracked the difficult problem that this type of jig integral installation greatly can't earth potential live be installed because of weight.Adopt and decompose the method for installing, jig is detachable, and preceding card can pass through double bundle conductor flexibly, the function of reliable locking device is arranged; Reduced the weight when jig is installed; This method both can be simplified operation procedure, alleviated operating personnel's labour intensity, reduced the danger of live line working; Increase work efficiency, improved power supply reliability and maintenance benefit again greatly.Can under charged condition, each parts of kit be installed on the live wire branch's decomposition and provide a kind of, and then each parts is assembled this jig

Embodiment
Below in conjunction with embodiment the present invention is described in more detail.
A kind of breakdown earth potential shown in Fig. 1-3 is changed the preceding card of jig, and described preceding card is wing card, and the both ends of wing card two flanks are square open slot 1; The plane extension direction of the opening direction of described open slot and wing card two flanks parallels; On two trough rims up and down of wing card two flank open slots, offer the positioning through hole 11 of mutual perforation, on wing card, also be provided with a lockweight 2, this lockweight is movably connected on the positioning through hole place on wing card two flanks; Before before the insulation arm-tie snaps in this, blocking two flank open slots; Described lockweight utilizes keeper 3 to be located trough rim place on two flank open slots, and the insulation arm-tie is provided with the through hole that can insert lockweight, when before the insulation arm-tie inserts, blocking two flank open slots; Push keeper aside; Then lockweight freely falls under the effect of deadweight, and the position of putting in order insulation board through key makes lockweight accomplish the action that latches, and pins insulation arm-tie and preceding card.The mode that lockweight is movably connected on wing card two flanks is: along lockweight axially offer one section logical heart slotted hole 21, in logical heart slotted hole, be provided with and can lockweight be stuck in the latch 22 on the wing card.Described keeper or be flexure strip.Spring leaf cuts with scissors on preceding card.
