The utility model discloses the constitution includes: the novel steel wire rope comprises a base plate (3), wherein the base plate is of an integrated structure formed by three triangular plates (7) in a surrounding mode, a sliding plate (1) is arranged between every two adjacent triangular plates, the sliding plate is connected with the base plate through a fixing bolt (5), strip-shaped gaskets (6) are sleeved on the upper side and the lower side of a stud of the fixing bolt, the length of each strip-shaped gasket is larger than the width of the corresponding sliding plate, and a sliding hole (2) formed by combining a strip-shaped hole and a conical hole is formed in the corresponding sliding plate. The utility model is used for high-voltage motor neutral point's quick wiring.
Description
The technical field is as follows:
the utility model relates to a high-voltage motor neutral point quick termination.
Background art:
when a large high-voltage motor adopts star connection, because the motor current is large, a motor neutral point lead is usually led out to a motor neutral point junction box and is connected through 3 silver-plated copper connecting sheets after being led out by an insulating small sleeve.
Because 3 link pieces adopt joint portion mutual stack installation, even if 3 link pieces install the gasket additional, also be difficult to keep on a plane during the installation, there is contact surface crimping insecure, in addition there are electromagnetism, mechanical vibration during the motor operation, link piece contact surface oxidation, go back and forth during the maintenance and demolish scheduling problem, cause the problem that contact resistance is bigger than normal between the link piece, at the current heavy current especially motor start-up moment or stand external short circuit impact, cause the high voltage motor trouble of neutral point link piece burnout, influence enterprise's safety in production.
The utility model has the following contents:
the utility model aims at solving present high-voltage electric shock star connection and needing 3 even pieces to lead to the not real problem of crimping, provide a high-voltage motor neutral point quick termination who adopts a bottom plate to connect.
The above purpose is realized by the following technical scheme:
the utility model provides a quick termination of high-voltage motor neutral point which constitutes includes: the novel steel wire rope comprises a base plate, wherein the base plate is of an integrated structure formed by three triangular plates in a surrounding mode, a sliding plate is arranged between every two adjacent triangular plates, the sliding plate is connected with the base plate through a fixing bolt, strip-shaped gaskets are sleeved on the upper side and the lower side of a stud of the fixing bolt, the length of each strip-shaped gasket is larger than the width of the corresponding sliding plate, and a sliding hole formed by combining a strip-shaped hole and a conical hole is formed in the corresponding sliding plate.
In the high-voltage motor neutral point quick wiring device, the thickness of the sliding plate is equal to that of the bottom plate.
Has the advantages that:
1. the utility model discloses a set up the three set-square and enclose the integral type bottom plate that closes formation, can pass the sliding hole of sliding plate and pass through the bolt fastening with the three lead joint of high-voltage motor neutral point according to high-voltage motor neutral point lead joint's position, can accomplish the neutral point connection work fast to can guarantee that the neutral point connects crimping face on a horizontal plane, avoid the dislocation, do not cause contact resistance increase problem such as strength, eliminate the potential safety hazard that contact failure brought, guarantee high-voltage apparatus safe and reliable operation.
2. The utility model discloses set up the sliding plate, the sliding hole that the combination of bar hole and bell mouth formed has in the sliding plate, in passing the sliding hole of three sliding plate respectively with the three pin joint of high-voltage motor neutral point like this, then make the side and the pin joint contact of its sliding hole according to the position of pin joint's diameter adjustment sliding plate, then install gasket and fixing bolt on the pin joint and make sliding plate and bottom plate fixed, again with mounting nut on the pin joint, can satisfy the high-voltage motor's of different models connection like this, even three pin joint's position is different, the diameter difference that connects can be installed fixedly through the position of adjustment sliding plate.

fig. 1 is a top view of the present invention;
FIG. 2 is a front view of the present invention;
FIG. 3 is a schematic view of the construction of the base plate;
FIG. 4 is a schematic view of the construction of the slide plate;
in the figure: 1. a sliding plate; 2. a slide hole; 3. a base plate; 5. Fixing the bolt; 6. a strip-shaped gasket; 7. a set square; 8. a back plate; 9. and a lead connector.
The specific implementation mode is as follows:
example 1:
the utility model provides a quick termination of high-voltage motor neutral point which constitutes includes: the novel steel wire rope comprises a base plate 3, wherein the base plate is of an integrated structure formed by three triangular plates 7 in a surrounding mode, a sliding plate 1 is arranged between every two adjacent triangular plates, the sliding plate is connected with the base plate through a fixing bolt 5, strip-shaped gaskets 6 are sleeved on the upper side and the lower side of a stud of the fixing bolt, the length of each strip-shaped gasket is larger than the width of the corresponding sliding plate, and a sliding hole 2 formed by combining a strip-shaped hole and a conical hole is formed in the corresponding sliding plate.
Example 2:
according to the neutral point quick wiring device of the high-voltage motor in the embodiment 1, the thickness of the sliding plate is equal to that of the bottom plate.
The installation process comprises the following steps: respectively passing the three lead connectors of the neutral point of the high-voltage motor through the sliding holes of the three sliding plates, then adjusting the positions of the sliding plates according to the diameters of the lead connectors to enable the side surfaces of the sliding holes to be in contact with the lead connectors, then a strip-shaped gasket is sleeved on the stud, then the stud is sleeved with a gasket after passing through the sliding hole, and then the upper end and the lower end of the stud are screwed with fixing nuts, thus realizing the fixation between the sliding plate and the bottom plate, meanwhile, the gasket is arranged to ensure that the sliding plates and the bottom plate are arranged in the same plane after being installed, the other two sliding plates and the bottom plate are fixed by adopting the method, and then the lead connector is provided with the nut, so that the lead connector is installed on the sliding plates, and the connection of high-voltage motors with different models can be met, even if the positions of the three lead connectors are different, the diameters of the connectors are different, and the connectors can be installed and fixed by adjusting the positions of the sliding plates.
