Description
Technical field
The conduction that the utility model the relates to a kind of High-Voltage Electrical Appliances parts that are slidingly connected are more specifically to a kind of Mume flower contact that is used for High-Voltage Electrical Appliances.
Background technology
Mume flower contact is a kind of conduction commonly used in High-Voltage Electrical Appliances parts that are slidingly connected.Existing Mume flower contact generally is made up of contact, bracing frame, extension spring, fixed contact, conducting rod.
Because contact is relatively thinner, contact-making surface is smaller, must adopt bracing frame to install, and adopt the extension spring more than two to tighten, this makes Mume flower contact have following shortcoming: the contact-making surface utilance is low, resistance is big, the assembling difficulty, need that frock clamp is assisted, overall dimensions are big.In addition, precision prescribed height during the butt joint of existing Mume flower contact, error need be controlled in the very little scope, and axial error directly influences the size of contact resistance, more can cause butt joint not when serious fault.
Therefore, existing Mume flower contact breaking capacity is not high, generally only uses as isolating.
Summary of the invention
The purpose of this utility model is that prior art is improved, and a kind of Mume flower contact that is used for High-Voltage Electrical Appliances is provided, and is can contact resistance smaller, allows bigger butt joint error, and stable performance has high breaking capacity, and the technical scheme of employing is as follows:
The Mume flower contact that is used for High-Voltage Electrical Appliances of the present utility model, comprise plum blossom fixed contact, plum blossom moving contact conducting rod and plum blossom moving contact, plum blossom moving contact conducting rod is connected with an end of plum blossom moving contact, it is characterized in that: described plum blossom moving contact is made up of at least two plum blossom fingertips, all plum blossom fingertip middle parts connect by fixture, form the sleeve of hollow, an end of plum blossom moving contact connects plum blossom moving contact conducting rod, and the other end of plum blossom moving contact props up the surface of plum blossom fixed contact.When plum blossom moving contact conducting rod drives the plum blossom moving contact to the first lateral movement of plum blossom stationary contact, the relative plum blossom moving contact motion of plum blossom fixed contact, insert in the plum blossom moving contact, when plum blossom moving contact conducting rod drives the plum blossom moving contact to away from the first lateral movement of plum blossom stationary contact the time, the relative plum blossom moving contact motion of plum blossom fixed contact is withdrawed from the plum blossom moving contact.
Described plum blossom moving contact and the internal diameter of the corresponding end of plum blossom fixed contact are slightly less than the external diameter of plum blossom fixed contact.Like this, the motion of the relative plum blossom moving contact of plum blossom fixed contact is withdrawed from or is inserted in the plum blossom moving contact the process in the plum blossom moving contact, and the plum blossom moving contact can remain with the plum blossom fixed contact and contact.
The medial surface of described plum blossom moving contact and the corresponding end of plum blossom fixed contact is arc surface ringwise, and the plum blossom fixed contact contacts an end with the plum blossom moving contact lateral surface is a cambered surface.Like this, the motion of the relative plum blossom moving contact of plum blossom fixed contact is withdrawed from or is inserted in the plum blossom moving contact the process in the plum blossom moving contact, the contact area of plum blossom moving contact and plum blossom fixed contact is bigger, can effectively reduce contact resistance, and also is convenient to the relative plum blossom moving contact motion of plum blossom fixed contact.
The corresponding end with the plum blossom fixed contact of described plum blossom moving contact is provided with the copper-tungsten layer, and the corresponding end with the plum blossom moving contact of plum blossom fixed contact also is provided with the copper-tungsten layer.Like this, the motion of the relative plum blossom moving contact of plum blossom fixed contact is withdrawed from or is inserted in the plum blossom moving contact the process in the plum blossom moving contact, causes that arc light only contacts on the copper-tungsten layer, because the refractory properties of copper-tungsten, therefore be not easy to damage, effectively guaranteed the useful life of plum blossom moving contact.
Described fixture is a spring coil, and spring coil is set in the holddown groove of plum blossom moving contact lateral wall.The process that the relative plum blossom moving contact motion of plum blossom fixed contact is withdrawed from the plum blossom moving contact, spring coil remains the extruding to holddown groove, thereby makes the corresponding end with the plum blossom fixed contact of plum blossom moving contact remain in this process and the contacting of plum blossom fixed contact.
The outer circumference surface of described plum blossom moving contact conducting rod is provided with draw-in groove, and the end that the plum blossom moving contact is corresponding with plum blossom moving contact conducting rod is provided with fixture block, and fixture block is located in the draw-in groove.
Described plum blossom moving contact conducting rod front end is provided with guide post, and the internal diameter of plum blossom moving contact madial wall and corresponding position, guide post position is slightly larger than the external diameter of guide post.Like this, can guarantee preferably that the plum blossom moving contact can aim at the plum blossom fixed contact preferably with the opening of the corresponding end of plum blossom fixed contact, be convenient to the plum blossom fixed contact and insert the plum blossom moving contact.
The utility model beneficial effect against existing technologies is:
Reduced volume significantly saves material: the Mume flower contact compact conformation of this programme, and to be applied as example in 12kV 630A system, the Mume flower contact external diameter of this programme is less than 30 millimeters, and existing Mume flower contact external diameter then is greater than 50 millimeters.
1, contact resistance is smaller: to be applied as example in 12kV 630A system, the Mume flower contact contact resistance of this programme is 20 μ Ω only, and existing Mume flower contact is then more than 40 μ Ω.
2, allow big butt joint error and stable performance: in 12kV 630A system, to be applied as example, the utility model in axial dipole field smaller or equal to ± 4mm, axial angle deviation during smaller or equal to ± 5 °, it is no problem not only to dock, and can not influence contact resistance.Existing Mume flower contact then have only axial dipole field smaller or equal to ± 1mm, axial angle deviation smaller or equal to ± 0.5 °, and contact resistance increases with the butt joint error.
3, has high breaking capacity: in 12kV 630A system, to be applied as example, but the utility model disjunction 31.5kA short circuit current, only use and existing Mume flower contact is general as isolating, can not cut-off by on-load, even if a few modified model possesses the Mume flower contact that on-load cut-offs, its breaking capacity also is below the 12.5kA.
