Abstract
A solid-insulation type sheathed connecting element for gas- insulated switchgear and particularly for making an electrical connection between components of the switchgear, has an insulated contact bushing between gas-insulated chambers. The solid-insulation type sheathing (FU) of the connecting element (VE) is formed by a heat-conducting synthetic resin compound, and makes heat-conducting connection with a number of cooling body elements (KK...) matched to the its outer contour. Said connecting element is used in gas- insulated switchgear with a metallic housing to realize supplement and distribution of energy, preferably ones with medium voltage.
Description
The present invention relates to a kind of Connection Element with solid material insulating sheath, be used to gas-insulated switchgear with metal shell, be electrically connected especially for setting up between the parts of medium voltage switchgear equipment, it comprises the contact channels of an insulation between gas-insulated container.
Connecting the male part that is arranged on each parts in the isolated gas-insulated switchgear is a kind of bus device, and it is disclosed among the Germany Patent document DE 4001909A1.The bus that is connected has bolt rod in its end, and it can be inserted in the socket of correspondence of male part, connects thereby set up conduction between switchgear.Each male part is all drawn in the gas-insulated district of switchgear through a so-called contact channels.Described male part itself is actually an element that is tightly connected between switchgear, and it insulate to the outside.
In addition, also disclosing a kind of electrical couplings part that is used for the gas-insulated service area in DE 19737429 A, itself is not the element that is tightly connected.Wherein gas isolated service area is connected with air tight manner with a shell that electrically contacts passage, and the chamber wall of the latter and respective switch equipment is complementary.Irrelevant with sealing, the male part of conduction is owing to bearing electric load, so must adopt bigger shape of cross section.
Task of the present invention is, a kind of Connection Element with solid material insulating case is provided, and it has the advantage of two kinds of known coupling elements, and it is simple in structure and compact, has bigger current capacity ability simultaneously under the identical situation of structure.
Solution of the present invention has following feature:
1.1 the solid material insulating case of described Connection Element is to make with a kind of casting resin material with thermal conductivity,
1.2 the solid material insulating case of described Connection Element links to each other with a plurality of cooling element heat conduction, described cooling element and insulating case outline match.
The casting resin that has thermal conductivity by use is made the solid material insulating case that is used for described Connection Element, and distribute heat towards periphery is when current-carrying part measure-alike thereby have a higher current capacity ability.Main points of the present invention are, have also additionally used some cooling elements, utilize them heat outwards can be distributed in mode rapider and that strengthen from the zone of bearing current capacity.
Constantly requiring to reduce the structural volume of this switchgear, and when wishing that each parts of this switchgear are compact more, can under the situation that guarantees same current capacity ability, make the structural volume of Connection Element become minimum on the contrary.
A kind of favourable structure of the present invention has following feature:
2.1 described cooling element is made of the single cooling element of half hull shape,
2.2 connecting by bolt in paired mode, the single cooling element of described half hull shape links together in removable mode,
2.3 the single cooling element of described half hull shape designs by a structural module with the parts phase configuration of switchgear.
The cooling element design structure is become the single cooling element of half hull shape, in fact can make it successfully to fit together at any assembling stage with Connection Element.Removable in addition bolt connection is fixed together single cooling element in pairs, can prevent expensive maintenance process, for example changes the single part that damages.Described single cooling element has the structural module that is consistent with the switchgear parts, it makes Connection Element itself realize standardized structural on the one hand, can use miscellaneous part when needed on the other hand, replace single cooling element as power pack and/or voltage changer.And cooling element can guarantee to have enough cooling effects, and is irrelevant with its level or vertical installation site.
The favourable structure of another kind of the present invention has following feature:
3.1 described Connection Element has hitching post tee section profile, and is positioned at it and becomes to be equipped with one first lug plate and one second lug plate on the free end outside solid material insulating case steppedly,
3.2 described first lug plate connects by bolt and the wiring body of gas isolated contact channels connects together,
3.3 described second lug plate connects by another bolt and a parts conduction of described switchgear links together.
Connection Element adopts hitching post tee section profile, its free end that is positioned at outside the solid material insulating case is transited into first and second lug plates steppedly, thereby constituted a kind of Connection Element of being convenient to make, it is connected by removable bolt with the connector of contact channels and other elements has realized that simple conduction connects.
The favourable structure of another kind of the present invention has following feature:
4.1 the parts of described switchgear are realized by a busbar joint.
What occur in this structure can successfully distribute by described Connection Element fast than the heat-flash loss.
The present invention is further illustrated for contrast accompanying drawing illustrated embodiment below, and this accompanying drawing 1 is expression Connection Element and the combined three-dimensional exploded view of contact channels.
Described Connection Element VE has first and second flat lug plate AS1 and the AS2 respectively at two free end, and they are not covered by solid material insulating case FU.The wiring body AT of described as can also be seen from Figure in addition contact conductive channel KD, it can be connected with the first lug plate AS1 conduction of Connection Element VE by a releasable connection that schematically shows.Cover plate AB constitutes a part of same unshowned airtight welded vessel with unshowned known manner.Described contact conductive channel KD adopts conductive channel shell DA and as known in the art in conjunction with the pressure effect of stage clip DF on pressure ring DR, equally airtightly with described seal of vessel.In addition in this embodiment, the heat dissipation element that under assembling finishes state, constitutes by two independent cooling element KK1 and KK2, in conductive channel shell DA zone described Connection Element VE is covered, and with Connection Element VE because the solid material insulating case FU of the heat that current load produces by heat conduction is transmitted to the external world.
In addition as shown in the figure, the hitching post tee section profile that Connection Element VE directly is connected with the second lug plate AS2 is covered by another cooling element, and the latter is made up of independently cooling element KK3 and KK4, so the interior heat radiation of Connection Element VE scope is actually double.
Particularly shown in the 4th independent cooling element KK4, connect independent cooling element KK3 and the KK4 that SV is fixed together by bolt, the zone line with solid material insulating case FU surrounds basically, and the performance conductive force, thereby can realize effective heat transfer.By on described Connection Element VE, cooling element being set flexibly, thereby also can replace these cooling elements with other parts that can conduct heat in the same manner where necessary.
