Summary of the invention
Therefore, technical problem to be solved by this invention provides a kind of link block that can reduce sealing surface quantity.
According to the present invention, this technical problem solves by the link block of the described type of beginning, that is, encapsulating housing has at least one outstanding convex shoulder on the encapsulating housing inwall, in this convex shoulder upper support one instrument transformer (Messwandler) is arranged.
Provided the possibility that instrument transformer is set in the inside of link block by the outstanding convex shoulder on the encapsulating housing inwall.Instrument transformer can be approaching via second flange connector, and the housing that therefore no longer needs to be installed in the electrical switchgear on second flange connector separates.Reduced the quantity of used seal thus.For assembling purpose or maintenance purpose, link block itself can be pulled down from switching device or electric conductor, and be carried out assembly work in link block inside.
At this advantageously, so construct link block, make portion's guiding within it that the electric wire group of a plurality of mutual maintenance electric insulations be arranged.The advantage of this structure is that link block also can be applied in the heterogeneous electric energy transmitting net.Usually link block is the part of so-called distribution panelboard, and described distribution panelboard is formed by several independent modules usually, and wherein, each module has at least one encapsulating housing, and each encapsulating housing for example interconnects by flange connector.Each module for example is the bus-bar section, disconnect, earthed switch, instrument transformer module, circuit breaker or the like.Using under the situation of link block, distribution panelboard can be connected electric conductor, cable for example, and aerial condutor or other are applicable on the power transfer of long-distance transmissions electric energy.Can in the electric energy transmitting net, set up open position by means of electrical switchgear.Primary cut-out is particularly useful for this, is applicable to according to its structure primary cut-out, both can repeatedly disconnect rated current, also repeatedly open failure electric current, especially short circuit current.
Another kind of favourable structure is designed to, and outstanding convex shoulder is around a main shaft.
One around the convex shoulder of main shaft, especially coaxially around convex shoulder make that instrument transformer can be towards the corresponding predetermined position, angle of encapsulating housing inside.In addition, annular convex shoulder makes that the power that occurs can be along contact wire transmission relatively large between convex shoulder and the encapsulating housing.Thus, the magnetic force that for example can under the situation of short circuit step-like be occurred is delivered in the encapsulating housing in improved mode.Around constructing piecemeal.If convex shoulder sealing ground is around being especially favourable.In addition, can be when annular convex shoulder is set convex shoulder be used to reinforce encapsulating housing.The convex shoulder of annular works by the form of rib, and it strengthens encapsulating housing on the one hand, is used as the holding device of instrument transformer on the other hand.
Instrument transformer for example can be used for the flow through electric current of the conducting line segment that is arranged on encapsulating housing inside of conversion and reflection.Yet, also can be designed as, instrument transformer is used to measure with conversion and is carried in voltage on the electric lead section.Both can be designed as at this, instrument transformer is used to measure the electrical quantities of the single phase of polyphase system, and perhaps instrument transformer is used to measure the electrical quantities of a plurality of phases of polyphase system.
The convex shoulder of annular can be according to the form design of ring, and wherein, instrument transformer abuts on the ring surface at least.Yet, also can design annular convex shoulder and on this disk, be provided with a plurality of grooves, thereby the convex shoulder of annular is configured on the inwall of encapsulating housing by disc format.
Another favourable structure can be designed as, that is, convex shoulder is connected with the encapsulating housing wall material with engaging.
The connection that material engages for example can be by realizing outstanding convex shoulder welding or soldering in encapsulating housing.Because the encapsulating housing especially in nip territory and the high-pressure area also is designed to airtight encapsulating housing, so when the overvoltage of design encapsulating housing inside, encapsulating housing must have enough mechanical strengths.This is under normal conditions by using metal material to realize for encapsulating housing.Metal material can be with simple mode moulding, and also can by means of corresponding method of attachment (welding, soldering etc.) material joint be provided with outstanding convex shoulder.
Yet, also can be designed as, outstanding convex shoulder for example is molded on the encapsulating housing by casting process in the scope of the manufacture process of encapsulating housing.Thus can be effectively and produce a plurality ofly apace by encapsulating housing of the present invention, described encapsulating housing can be made under the situation that guarantees enough quality when producing in enormous quantities at an easy rate.
Can advantageously be designed in addition, outstanding convex shoulder is different with the flange that is designed for other element of connection.
By outstanding convex shoulder can relative compartment of terrain far away with the opening of encapsulating housing be that instrument transformer forms the stopper point.Describedly have in a plurality of distribution panelboards by the interconnective encapsulating housing of flange respectively in beginning, except linkage function, flange also usually is used to the assembly and the location that keep extra.In assembling process, consider the assembly that correspondingly to locate for this reason.The assembly method that this need expend.
Outstanding convex shoulder (this convex shoulder and flange are arranged with being separated by) by independent design for example can just be arranged on instrument transformer this link block inside in the modular preproduction process of link block.At this, when for example being connected with the encapsulating housing of circuit breaker, link block need not to consider again the location of instrument transformer, because this instrument transformer has occupied its final position with respect to encapsulating housing in link block inside.
Another kind of favourable structure is designed to, and a flange connector is towards the main shaft direction, and another flange connector extends substantially transversely to the main shaft orientation.
When use has the flange of collar flange face, can advantageously be designed to, make extend past collar flange face central point axis in this wise towards, that is, and the flange that ring-type is extended and this axis coaxle ground orientation.This axis for example is the main shaft of encapsulating housing.
Flange connector usually is equipped with the flange surface of annular.Described flange surface is suitable for corresponding tubular flange to be taken over, and this flange adapter is directed with the axis coaxle ground of the central point of extend past collar flange face.Flange surface and flange are taken over and are formed flange.Can advantageously be designed at this, make that the flange axis extends thus defined on the main shaft direction.Flange axis and main shaft orientation coaxially are especially favourable.Correspondingly, the flange axis of another flange connector can be transverse to the main shaft orientation, wherein, forms an intersection point at the main shaft and the flanged shaft line of another flange, and therefore, this flange axis is along the radially extension of main shaft.At this, the angle that forms 90 ° between the flange axis of two flange connectors is favourable.Thus, link block for example can advantageously be used on distribution panelboard, and this distribution panelboard is installed in the building and only has limited space.Therefore, electric conductor can be introduced link block from the position of perpendicular, and pass on 90 ° of ground of link block interior deflector, make connector pass to be used to connect second flange connector of electrical switchgear, described connector is the along continuous straight runs orientation basically.In addition, provided such possibility by this angled position, that is, the encapsulating housing of link block can set other flange, and described flange cooperates with other assembly when needed.

Disc insulator is such insulator, and it has the flat extension of being passed by electric conductor to be fixed, and wherein, electric conductor extends substantially transversely to its longitudinal axis plate-like ground and centered on by insulating material.Such disc insulator for example can keep according to the type of the insulating sleeve of electric conductor.At this, disc insulator seals or is supported on the outstanding convex shoulder is especially favourable, therefore, compares with case material, and the dielectric material block of difficult moulding is firm.Can be designed as, that is, disc insulator is surrounded by a shelf attachment (Fassungsarmatur) extraly for this reason, and disc insulator links to each other with a shelf attachment, and described shelf attachment contacts with the convex shoulder of giving prominence to.At this, disc insulator can be designed as single-phase disc insulator or heterogeneous disc insulator.In heterogeneous disc insulator a plurality of electric conductors by one or more disc insulator electrically insulated from one another fix.When using a plurality of disc insulator, the convex shoulder of annular for example can form by plate, and wherein, this plate has a plurality of grooves, and described groove sets a disc insulator respectively.So the insulator arrangement that forms is supported on the outstanding convex shoulder.
Another kind of favourable structure can be designed as, that is, seal abuts on the outstanding convex shoulder airtightly.
Provided the possibility that disc insulator itself is installed in the inside of encapsulating housing as barrier (Barriere) by airtight transition to outstanding convex shoulder.This barrier is airtight barrier at this, therefore, can not realize Gas Exchange via seal.Thus, the zone that wherein is provided with instrument transformer of encapsulating housing can separate with other zone of encapsulating housing.Therefore, for example can protect instrument transformer not to be subjected to electric arc influence.Electric arc for example can occur when the encapsulating housing internal fault.
Make insulator arrangement have the groove that insulating gas can flow through yet also can be designed as.
Another kind of favourable structure can be designed as, that is, encapsulating housing surrounds a disconnect at least in part.
In addition, can be designed as equally, that is, encapsulating housing surrounds an earthed switch at least in part.
Each conductor segment and other conductor segment of link block inside can be disconnected by disconnect or earthed switch.Therefore, for example can disconnect conductor and the conduction between the electric switch of introducing link block by disconnect connects.Can carry the conductor segment of electrical power to load being designed for of encapsulating housing inside by earthed switch with earth potential.This for example for security reasons is essential.
In the switching process of earthed switch or disconnect, although such switching device does not have the Power Groud switch, also electric discharge phenomena can appear in switching process.At this advantageously, distribute the inner available space of encapsulating housing, make the electrical switchgear that is arranged on encapsulating housing inside to small part separate with instrument transformer by insulator arrangement.Thus, instrument transformer is protected and avoids effect of arc.In addition, observe destructive effect under the situation of using high pressure sulfur hexafluoride, described destructive effect takes place when electric arc produces.Analyte in this formation can damage instrument transformer.Therefore, it is favourable by means of insulator arrangement other parts of instrument transformer and encapsulating housing inside being separated.
