Description
Technical field
The present invention relates to a kind ofly be applied to metal shell, gas isolated functional space zone, implement the charge coupled device of parts as contact, be particularly useful between the functional space zone of medium-voltage distribution device, setting up and be electrically connected.
Technical background
Germany Patent document DE 19502062 A1 disclose a kind of as contact enforcement parts and the connected charge coupled device of bus.Wherein, the four-way pipe that parts are designed to accept bus is implemented in this contact.Wherein, can form the end regions of the contact screw that is electrically connected, be sealed by a kind of airtight and watertight padding as so-called busbar joint with the functional space zone.It realizes that with being connected by a through bolt of gas isolated functional space zone the latter is installed on the airtight inside of wearing the wall sleeve.The connection of bus can realize under the situation in the functional space zone of not damaging inflation thus, that is to say, bus is connected and disconnection mutually with the functional space zone of inflation, does not need to do the reprocessing work relevant with insulating gas.
Summary of the invention
The objective of the invention is to, a kind of charge coupled device of implementing parts as contact is provided, it similarly should be closed outside the functional space zone, but its constructions cost reduces significantly, and this coupling element just is not used for bus and connects, but the conduction that usually is extended between the functional space zone connects.
Purpose of the present invention can be applied to metal shell by a kind of, gas isolated functional space zone, charge coupled device with contact enforcement parts realizes that it is particularly useful for setting up and is electrically connected between the functional space zone of medium-voltage distribution device, wherein:
1.1. described charge coupled device has the conductive connecting element of a bolt shape, on its first termination, has first brace that all is flat with respect to the longitudinal axis, and on its second termination, has one second brace, it has at least one longitudinal axis with respect to link and is horizontal fastening screw pit on the flat horizontal surface of first brace
1.2. described link is covered by the seal member of a housing shape to top, position therebetween, the sealing parts have one laterally perpendicular to the ring-type casting plate bearing of the longitudinal axis of link,
1.3. described link is limited by the seal closure of a housing shape in the zone of first brace, sealing covers on the cavity that forms a locking in the first brace zone,
1.4. the zone of the formation cavity of described seal member and described seal closure all has a current potential conducting shell,
1.5. at described seal member from the casting plate bearing to adjacent seal closure, with closing cap and distolateral border, on the appearance profile that in the longitudinal axis zone of charge coupled device, extends, and in the interior zone of casting plate bearing, all has one in the zone inside lap of boundary separately, continuously the earthing potential conducting shell of conduction.
The seal member of described housing shape utilizes its ring-type casting plate bearing to hide the sidewall in functional space zone, utilizes externally locking airtightly of link that this housing shape seal member can be implemented in the stud-shape in the functional space zone easily.Link in outside, functional space zone is limited by described seal closure, and its cavity holds the first flat brace of link.Described seal closure optionally can be removed, and can not change the gaseous state in the functional space zone.
According to a preferable embodiment of the present invention, it has following feature:
2.1. the locking cavity of described seal closure has a stop surface that is provided with perpendicular to the longitudinal axis of link on the free end of first brace,
2.2. this cavity is conical expansion to seal member, and ends at a circular contour place to the free end expansion of second brace, the latter equally also constitutes the current potential conducting shell.
Utilize the stop surface in the seal closure, link can be supported with preventing responsive to axial force in an advantageous manner, in addition, can be in large area the current potential of link be transmitted on the set current potential conducting shell.Circular contour in the zone of next-door neighbour's seal member can conduct the current potential of current potential conducting shell equally.
According to another preferable embodiment of the present invention, it has following feature:
3.1. connect along the bolt of the longitudinal axis effect of link by one, make between seal closure and the seal member removably to be connected,
3.2. it is on a flange ring that is arranged in the seal closure zone that described bolt connects, and realizes by 3 bolt connecting devices that are symmetrically distributed on it.
Utilize described flange ring that seal closure is pressed on the position that this link stretches out in the functional space zone.Be the link formation one tight locking outside the functional space zone thus.
Description of drawings
The present invention is described in further detail to utilize the accompanying drawing illustrated embodiment below.
Fig. 1 is the partial cutaway diagrammatic sketch of charge coupled device of the present invention.
Embodiment
Only illustrate in this figure for understanding part essential to the invention.
Described charge coupled device mainly is made of link AT.This link is in the FB of functional space zone, and partly sealed parts VT covers; And outside the FB of functional space zone, fully sealed cover AK covers.Described link AT has first brace VS1 on its first termination, and has second brace VS2 on its second termination.Wherein, first brace VS1 laterally has the through hole of a band clamp nut bearing at it perpendicular to a side of the longitudinal axis of link AT, and second brace VS2 similarly laterally has fastening screw pit BB on a pair of connection horizontal plane that is positioned at first brace VS1 at it perpendicular to a side of the link AT longitudinal axis.In addition, can obviously see by accompanying drawing, described seal cover has the thin slice of annular and accepts slit BA in the appearance profile scope of functional space zone FB, wherein rabbeted a covering plate that does not further indicate, and this covering plate makes the inside in functional space zone with respect to the airtight locking in outside.As previously mentioned, the seal closure AK that can load onto from the outside forms the sealing to link AT.Sealing cover on the adjacent zone of first brace VS1 in have a stop surface AF.Be coated with a current potential conductive layer PL on the whole cavity HR inwall of seal closure AK.The latter links to each other with the current potential of link AT by stop surface AF.Similarly, the circular contour RK of seal closure AK also is positioned on the current potential of link AT.On the contrary, the appearance profile of seal closure AK is guided to the current potential conductive layer EL of ground connection for security consideration.Connect SV and by flange ring FR, make seal closure AK plane compress seal member VT by bolt, wherein said bolt connects 3 bolt connecting modes of employing.
