110kV bus plug-in strip downlead cable clamp protector
Technical field
The utility model relates to 110kV bus plug-in strip downlead cable clamp protector.
Background technology
Electric substation will carry out switch tool when maintenance, in order to carry out the checking experiment of disconnecting link in the situation that bus does not have a power failure, needs charged the bus leading wire clamp that rolls off the production line to be taken apart, makes disconnecting link not charged, thereby carries out the checking experiment of disconnecting link.The connection of downlead and disconnecting link is generally all used copper-aluminium transition wire clip, and copper-aluminium transition wire clip cannot bear very large moment of flexure in Cu and Al combination portion, and crack easily occurs.After charged dismounting downlead, downlead hangs down to ground, at this time the weight major part of downlead is born by copper-aluminium transition wire clip, and produce a very large moment in Cu and Al combination portion, have certain impact when downlead is putting down in process, to such an extent as to even rupture in generation crack, Cu and Al combination place.
Utility model content
The purpose of this utility model is to provide 110kV bus plug-in strip downlead cable clamp protector, can effectively solve the problem of the stressed excessive easy generation fracture of Transition wire clip of existing downlead and disconnecting link.
In order to solve the problems of the technologies described above; the utility model is achieved through the following technical solutions: 110kV bus plug-in strip downlead cable clamp protector; comprise base plate, be arranged on the grab that blocks downlead wire clamp on base plate, be arranged on bracing or strutting arrangement that base plate bottom level regulates, be arranged on the clip lead protection supporting plate on base plate afterbody, described clip lead protection supporting plate is arranged on base plate by arrangement for adjusting height.
Preferably, the cross section of described clip lead protection supporting plate is semicircular arc; Make downlead be positioned at all the time clip lead protection supporting plate, can not skid off.
Preferably, described arrangement for adjusting height comprises prismatic head, is fixed on head bottom surface and the threaded adjusting rod to downward-extension, the diameter of described adjusting rod is greater than the circumscribed circle diameter of head, on described clip lead protection supporting plate, have the through hole suitable with head, the length of described through hole is more than or equal to the height of head, has first screwed hole suitable with adjusting rod on described base plate; Just can regulate height as long as rotate wire clamp pilot protection supporting plate, and clip lead protection supporting plate can conveniently separate with adjusting rod, be convenient to transport and deposit, also be convenient to damage rear replacing.
Preferably, described bracing or strutting arrangement is bolt, and described base plate is provided with the second screwed hole passing for bolt; Facilitate the height of regulating base board.
Preferably, described grab has two, lays respectively at front portion and the middle part of base plate, and described the second screwed hole is on the base plate between two grabs; Make the wire clamp that blocks that two grabs can be firm.
Preferably, the position corresponding with each grab, the back side of described base plate is equipped with one and strengthens horizontal stripe, and all reinforcement horizontal stripes are all connected with a reinforcement vertical bar; Progressive one strengthens base plate, prevents bottom deformation.
Compared with prior art, the utility model has the advantages that: grab is hooked on downlead wire clamp, adjusting supporting device makes whole base plate be positioned at suitable height, then adjust to suitable height by rotating wire clamp pilot protection supporting plate, the downlead of about ten centimetres outside wire clamp is upwards held, ensure that the Moment of downlead is on downlead instead of on excessive wire clamp, this apparatus structure is simple, easy to use, in the time that downlead puts down, most impact and moment of flexure will be born by bracket, ensure the painstaking situation that fracture also just not can occur of Transition wire clip, the normal safety that has ensured maintenance is carried out.

Embodiment
Consult Fig. 1, Fig. 2, Fig. 3 is the embodiment of the utility model 110kV bus plug-in strip downlead cable clamp protector, 110kV bus plug-in strip downlead cable clamp protector, comprise base plate 1, be arranged on the grab 2 that blocks downlead wire clamp on base plate 1, be arranged on the bracing or strutting arrangement 3 that base plate 1 bottom level regulates, be arranged on the clip lead protection supporting plate 4 on base plate 1 afterbody, described clip lead protection supporting plate 4 is arranged on base plate 1 by arrangement for adjusting height 5, the cross section of described clip lead protection supporting plate 4 is semicircular arc, described arrangement for adjusting height 5 comprises prismatic head 6, be fixed on head 6 bottom surfaces and the threaded adjusting rod 7 to downward-extension, the diameter of described adjusting rod 7 is greater than the circumscribed circle diameter of head 6, on described clip lead protection supporting plate 4, have the through hole 8 suitable with head 6, the length of described through hole 8 is more than or equal to the height of head 6, on described base plate 1, have first screwed hole 9 suitable with adjusting rod 7.
Described bracing or strutting arrangement 3 is bolt, and described base plate 1 is provided with the second screwed hole 10 passing for bolt, and described grab 2 has two, lays respectively at front portion and the middle part of base plate 1, and described the second screwed hole 10 is on the base plate 1 between two grabs 2.
The position corresponding with each grab 2, the back side of described base plate 1 is equipped with one and strengthens horizontal stripe 11, and all reinforcement horizontal stripes 11 are all connected with a reinforcement vertical bar 12.
Grab 2 is hooked on downlead wire clamp, adjusting supporting device 3 makes whole base plate 1 be positioned at suitable height, namely this height can make grab 2 catch on downlead wire clamp and be unlikely to allow whole device unsettled, and then adjusting arrangement for adjusting height 5, by rotating wire clamp pilot protection supporting plate 4, just can allow clip lead protection supporting plate 4 also in a suitable height, the downlead of about ten centimetres outside wire clamp is upwards held, ensure that the Moment of downlead is on downlead instead of on excessive wire clamp, this apparatus structure is simple, easy to use, in the time that downlead puts down, most impact and moment of flexure will be born by bracket, ensure the painstaking situation that fracture also just not can occur of Transition wire clip, the normal safety that has ensured maintenance is carried out, semicircular clip lead protection supporting plate 4 also can ensure that downlead is wherein positioned at clip lead protection supporting plate 4 all the time.
The foregoing is only specific embodiment of the utility model, but technical characterictic of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification are all encompassed among the scope of the claims of the present utility model.
