Abstract
The utility model discloses a conductance pole with a meter band contactor and a dovetail groove for a gas insulation metal enclosed switch gear, which can be applied to simplifies the assembly of meter band contactor for gas insulation metal enclosed switch gear. In order to resolve the technical problem, the utility model adopts a technical proposal as follows: one or a plurality of dovetail grooves are made on the conductance pole; a small opening is made at the upper side or the lower side of the dovetail groove; the size of the opening is able to allow that the meter band contactor can be installed conveniently into the dovetail groove in certain direction; the size of the dovetail groove is able to allow that the meter band contactor can contact completely with the dovetail groove upon installation.
Description
Technical field
The utility model relates to a kind of conducting rod, particularly a kind of conducting rod that is used in the Cubicle Gas-Insulated Switchgear conducting system.
Background technology
The SF6 gas insulated metal enclosed swit chgear claims GIS again, with its high voltage large capcity, volume is little, failure rate is low and intelligent in extensive use all over the world.Contact in the contact system is the core component in gas insulated metal enclosed swit chgear and other high-voltage switch gear, plays electric action.The structural shape of existing SF6 High-Voltage Electrical Appliances contact is a lot, majority is a quincunx, contact blade book copper coin punching out slabbing fingertip, if this kind fingertip does not have reliable positioning design, may produce the fingertip displacement, cause loose contact, can make the fingertip serious burn, the accident impact operate as normal occurs so that weld.Because SF6 High-Voltage Electrical Appliances contact system majority is to adopt fingertip to add shock mount to be installed on the touch base, complex structure, volume is big, inconvenience is installed, the manufacturing cost height, the ability of damming is low, also there are some watchband contacts to be contained on the conducting rod, but its mode of grooving is undesirable, and inconvenience is installed, and damages watchband easily.
Summary of the invention
Technical problem to be solved in the utility model is to simplify the assembly difficulty of watchband contact in the Cubicle Gas-Insulated Switchgear.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: drive one or several dovetail groove on conducting rod, simultaneously open an osculum at described dovetail groove upside or downside, its osculum size is packed in the dovetail groove easily for making the watchband contact, the dovetail groove size for the watchband contact pack in the dovetail groove after its contact point can fully contact with dovetail groove.The width that the throat width of dovetail groove should be less than or equal to the oval coupling part of watchband contact and an end touch article and contact with, the bottom width of dovetail groove should equal the width of whole watch band contact head unit.The watchband contact is by the metal object of several two the watchband shapes that are positioned at two ends and form with two oval unit that connect that the touch article of two relative outer contacts and the relative outer contact of two touch articles connect.
Because the utility model adopts technique scheme, produced following beneficial effect: do not need to install additional touch spring and pedestal when the watchband contact is installed, from the osculum that dovetail groove upside or downside leave, the watchband contact packed in the dovetail groove, can guarantee that the installation of watchband contact is reliable, thereby the assembly difficulty of watchband contact and complexity are reduced greatly.And, have very high electronic and thermal stability, so improved in the Cubicle Gas-Insulated Switchgear conducting system ability of damming because the watchband contact is multiple spot contact in dovetail groove.
Description of drawings
Fig. 1 is for putting into the profile of the watchband contact in the utility model conducting rod;
Fig. 2 is the profile of the conducting rod of band dovetail groove;
Fig. 3 is the stereogram of the conducting rod of band dovetail groove;
Fig. 4 is the installation diagram of watchband contact, conducting rod and static contact seat.
Embodiment
The utility model is described in further detail below in conjunction with drawings and embodiments:
See Fig. 1, the unit of forming the watchband contact has two ends respectively to have 1, two contact 1, two contacts to link to each other with the touch article 2 that is positioned at two ends, and touch article 2 links to each other with middle two oval-shaped parts, and the watchband contact is connected to form by several such unit.The watch band contact head material adopts the bronze preferably book plate of elasticity punch process, and material should reach the standard of itself, and the manufacturing process of watchband contact must satisfy specific heat treatment requirements and surface treatment requirement.The watchband contact that machines will be deposited with the packing case of special use, to prevent to damage contact surface.
See Fig. 2, the profile of the conducting rod of band dovetail groove, the section of the dovetail groove on the conducting rod resembles dovetail, rectangular trapezoidal shape, the width that the section of the inlet face that trapezoidal upper base width is a dovetail groove should be less than or equal to the oval coupling part of watchband contact and an end touch article and contact with, the section of the bottom surface that the trapezoidal width of going to the bottom is a dovetail groove should equal the width of whole watch band contact head unit.
See Fig. 3, on conducting rod, reach four dovetail grooves 7 of the tolerance of relevant drawing regulation, simultaneously respectively open an osculum 8 at above-mentioned dovetail groove upside or downside, osculum 8 size is packed in the dovetail groove by certain installation direction easily for making the watchband contact, above-mentioned dovetail groove size for the watchband contact pack in the dovetail groove after its contact can fully contact with dovetail groove.The conducting rod that machines will be deposited with the packing case of special use, to prevent to damage contact surface.
See Fig. 4, in the osculum that multiple-contact watchband contact is opened along the dovetail groove upper and lower sides is packed dovetail groove into earlier, guarantee the certain deformation amount, make contact normal direction strain contact pressure reach setting.The conducting rod that the watchband contact will be housed again inserts in the static contact seat and satisfies contacting travel.Because the watchband contact is a multiple-contact, therefore have very high electronic and thermal stability, when the long-term work state, also satisfy reliable through-current capability.
Claims (2)
1. the conducting rod that can adorn the band dovetail groove of watchband contact, described watchband contact is by the metal object of several two the watchband shapes that are positioned at two ends and form with two oval unit that connect that the touch article of two relative outer contacts and the relative outer contact of two touch articles connect, it is characterized in that, on conducting rod, drive one or several dovetail groove, simultaneously open an osculum at described dovetail groove upside or downside, described osculum size is packed in the dovetail groove easily for making the watchband contact, described dovetail groove size for the watchband contact pack in the dovetail groove after its contact point can fully contact with dovetail groove.
2. the conducting rod of adorning the band dovetail groove of watchband contact according to claim 1, it is characterized in that, the width that the throat width of the dovetail groove that described dovetail groove is processed on conducting rod should be less than or equal to the oval coupling part of watchband contact and an end touch article and contact with, the bottom width of dovetail groove should equal the width of whole watch band contact head unit.
