Description

Power transmission device

The present invention relates to an electrical power transmission device including at least one first control panel and one second control panel that are connected to each other via a first busbar strand. 1 A first housing and a second housing having the same function are disposed within the extension portion of the busbar strand.

A power transmission device comprising a first control panel and a second control panel is known, for example, from the German utility model DE 298 16 915 U1. Here, the two control panels are connected via one busbar strand. In this case, the busbar strand includes first and second housings. Compensation elements are provided to bridge the distances between the equally functional housings of the busbar strand. The use of compensating elements not only compensates for the thermal expansion in the extension of the busbar strand, but also allows for widening variance in the configuration of known power transmission devices. However, in so doing the number of flanges and required sealing elements is increased. The sealing elements and flanges represent interference points within the power transmission device that, due to their respective individual assembly needs, require increased attention. In particular, the increased number of sealing elements presents a drawback with respect to long-term stability.

Accordingly, an object of the present invention is to specify a cost effective power transmission device while maintaining improved long-term stability.

The above object is, according to the invention, in a power transmission device of the type mentioned in the introduction, the first housing and the second housing each comprising interfaces for connection with additional assemblies, in particular housings, the first housing And the interfaces of the second housing differ from each other in the direction of the extension of the first busbar strand, and in particular are solved by having a fixed separation distance.

The power transmission device is used for transmission of electrical energy. To this end, a phase conductor is provided which is used to guide the current. The current is driven through the electric potential difference. The phase conductor is correspondingly electrically insulated to prevent ground faults and short circuits. Fluids such as liquids or gases are suitable for electrical insulation. Even more preferably, the phase conductor can be surrounded by a housing, whereby direct access to the phase conductor becomes difficult. In addition, the use of the housing allows sections of the phase conductor located inside the housing to also circulate around it by the electrically insulating fluid while still enclosing the electrically insulating fluid inside the housing. To this end, the housing can be formed as an encapsulating housing, whereby unintended leakage of the electrical insulating fluid disposed inside the housing is prevented. The phase conductor can be circulated around it by an electrical insulating fluid inside the housing, whereby electrical insulation of the phase conductor is performed. In this case, the phase conductor can pass through the wall of the housing in a fluid sealing and electrical insulation manner. For this purpose, the housing can be formed in an electrically insulating manner at least in some sections. The first housing and the second housing can be directly connected to each other, in other words, the interfaces are coupled to each other. The first housing and the second housing may be directly connected to each other, in other words, the interfaces are connected to an intermediate assembly and indirectly connected to each other through an intermediate assembly.

Depending on the respective requirements, single-pole insulation or multi-pole insulation can be used on the power transmission device. In the case of unipolar insulation, only phase conductors of the same pole are circulated around the same by the same electrical insulating fluid, and for this purpose, in general, a separate housing is provided for each of the electrical insulating fluid. In the case of multi-pole insulation, a plurality of phase conductors of different poles are circulated around them by the same electrical insulating fluid, and for this purpose are generally arranged in the same housing. The electrically insulating fluid insulates the individual phase conductors of the various poles from each other and to the encapsulating housing.

As the electrical insulating fluids, for example, fluorine-containing substances such as sulfur hexafluoride, fluorinated ketone, fluorinated nitrile, nitrogen, oxygen, carbon dioxide, mixtures in which these substances are involved, and the like are suitable. If necessary, the electrical insulating fluid can also be pressurized with excess pressure, whereby even more preferably the insulating strength of the electrical insulating fluid is enhanced.

Current can be transmitted by the power transmission device. In order to be able to control the corresponding wiring circuits or transmission paths, the power transmission device may include a plurality of control panels (at least one first and one second control panel). Via the control panel, for example, the supply line/ground line can be switched. In this way, generator lines, transformer lines, overhead lines, cables, etc. may be arranged on one control panel. The control panel comprises corresponding switching devices, for example earthing switches, disconnecting switches, power switches, load switches, and the like, in order to securely connect or disconnect the corresponding lines.

The control panels are even more preferably connected transversely via one busbar strand, so that the supply line/ground line of the first control panel and the supply line/ground line of the second control panel are connected via the busbar strand. Can be combined, so that energy flow can be carried out from one control panel to the other control panel. Even more preferably, a plurality of control panels may be disposed within one power transmission device, and the control panels are connected in a transverse direction via one busbar strand. Thus, if necessary, connection and disconnection or connection of various control panels or their supply lines can be performed.

For this purpose, the busbar strand comprises, for example, an electrically insulating phase conductor and a housing, from which control panels are branched in the form of a stitch. Switching devices of the same type, in particular disconnect switches, are preferably arranged in the first and second housings having the same function in order to be able to carry out the coupling or disconnection of the control panel to the busbar strand. Through the disconnect switches, it is possible to connect or disconnect each control panel to the fluid insulated busbar strand. The disconnect switch may also be a so-called three-position switch which can be used in addition to the disconnection/connection of the stitches of the phase conductors, for example also grounding the stitches of the phase conductors to the control panel. Even more preferably, for the formation of a compact power transmission device, the busbar strands may extend substantially transversely, in the direction of the depth axis, even more preferably perpendicularly to the transverse direction, several control panels They are arranged side by side with each other in the transverse extension in the shape of a comb.

In order to enable the power transmission device and in particular a modular construction of the first busbar strand therein, the first and second housings can be built into the busbar strands, inside themselves provided on the one hand for current transmission. It houses the phase conductors, and even more preferably, the electrical insulating fluid in an overpressure condition within them. Correspondingly, the first and second housings of the busbar strands can be formed as encapsulating housings, in particular as pressure tanks.

In order to allow variable extension of the first busbar strand in the transverse direction, the first and second housings can be connected to each other indirectly and directly via their interfaces. The housings house the above-described phase conductors within themselves. In this case, even more preferably, multi-pole insulation can be used. However, it is also possible to realize the structure according to the invention, in particular including a unipolar embodiment of the busbar strand. The housings each comprise interfaces, in order to be connected with further assemblies, in particular housings, for example a further first or further second housing. The additional assemblies comprise complementary interfaces, so that the interface of one housing can be closed via the additional assembly. By means of a further assembly, a fluid-tight closing of the housing can be effected. The further assembly may be a closed assembly, such as a blind flange or split insulator, for example. Further, the additional assembly can also be formed through the first or second housing. The interfaces are, for example, flanges, which flanges allow for a fluid-tight coupling of the housings, for example (optionally with split insulators arranged in the middle). In this case, bolt flanges which allow reversible connection of the individual housings have proven to be particularly suitable. The interfaces of the housings are even more preferably arranged on opposite sides of the housings and in a manner that is aligned in opposite directions, whereby the interfaces substantially perpendicular to the transverse axis each having opposite direction signs are It is formed not only on the first housing but also on the second housing. The distance between the interfaces of the first housing is estimated to be smaller or larger than the distance between the interfaces of the second housing. In either case, the distances between the interfaces of the first and second housings are different. In this case, the distance extends substantially in the transverse direction (transverse axis), and in this transverse direction also the phase conductor guided inside the housings also extends. Even more preferably, the distance between the interfaces on the respective housings is estimated as an angle-fixed type, that is to say the distance remains substantially the same regardless of the state of the power transmission device. In doing so, it is possible to form rigid housings each including defined interfaces having a relatively defined spacing (distance) between them. Between the interfaces, even more preferably the sealing-free wall of the respective housing extends. Even more preferably, between the interfaces an integral wall part, eg a cast mold, can extend. As housings, for example encapsulating housings which provide a fluid receiving chamber in their interior are suitable, the interface being closed sealingly, for example via an additional housing, or closed, for example via a divider (a further assembly). As the dividing portion, for example, a blind cover that allows closing of the interface can be used. Electrically insulating insulators, in particular disk insulators, can be used as the dividing part, and these insulators are penetrated by the phase conductor, for example in a fluid sealing manner. The dividing part (insulator/dividing insulator) can also be inserted into the flange coupling part (interface coupling part), for example.

According to another preferred embodiment, the first housings and the second housings may be alternately arranged in succession within the extension of the first busbar strand.

A plurality of first housings and a plurality of second housings may be disposed within the extension portion of the busbar strand, that is, in the direction of the horizontal axis. In this case, the arrangement should be provided in such a way that a second housing is formed following the first housing in the extension of the busbar strand, a first housing is formed in the further extension, and a second housing is formed thereafter. do. In doing so, on the one hand, a repeating sequence of positions of the interfaces within the extension of the busbar strand is achieved, but depending on the respective distances of the interfaces of the first to the second housing, a variable spacing between the interfaces will be realized. I can. Between the first housing and the second housing, an additional assembly can also be arranged. Additional assemblies can be, for example, divisions (split insulators), compensators, etc., which allow for example length variations. For example, so-called bellows may be used, and thermal expansion or the like occurring within the extension of the busbar strand may be compensated through these bellows.

According to another preferred embodiment, the first housings and the second housings may be arranged alternately in direct succession.

The first housing and the second housing may be alternately disposed within the extension of the first busbar strand in direct sequence and in succession. In this case, in particular, when the separation distance between the interfaces on the first housing and the second housing is fixed, the fixed separation of the continuously repeated positions of the interfaces connected to each other is also enforced. The direct continuation of the first housing and the second housing includes, for example, the use of support insulators, split insulators, etc. inserted into the interface joints of two first and second housings adjacent to each other. In this way, for example, a support insulator in the form of a disk can be inserted into the flange joint between the two housings, and through the support insulator, positioning of the phase conductor inside the housing relative to the housing is possible.

Furthermore, preferably, the housings can each surround one or more electrical switching devices, in particular switching devices of the same function.

However, in addition to the phase conductors used for the transfer of current and generally considered as passive elements of the power transmission device, active elements can also be used within the power transmission device. The active elements are for example electrical switching devices which are preferably present in the first to second housings in an enclosed manner. In so doing, there is a possibility of using an electrically insulating fluid located inside of the housings also as a switching fluid, for example to stabilize the switching path with dielectricity. The electrical switching device may in particular be a disconnect switch which is used to switch the stitches of the phase conductors of the busbar strands towards the control panel. For example, the disconnect switch can also be combined with a grounding switch, whereby the grounding of the stitches of the phase conductors of the busbar strands can be effected in some cases.

In the case of arranging the electrical switching device in the interior of the housing, for example for switching stitches, the use of switching contact pieces that are relatively movable with each other on the electrical switching device can be provided. In this case, the switching contact pieces that are relatively movable with each other can be positioned in such a way that their circumference is circulated by an electrically insulating fluid inside the housing. In order to be able to transfer the movement onto the switching contact pieces that can be moved relative to each other, a kinematic chain that passes through the housing, preferably in a fluid-tight manner, can be used, and driven by a driving device on the outside of the housing Movement can be created.

In this case, preferably, a drive device can be arranged on the side surface on at least one of the housings.

The drive device may be, for example, a spring-loaded drive, an electrodynamic drive, a pneumatic drive, a hydraulic drive, or the like. Further, through the arrangement of the side surfaces of the drive device, the possibility of providing one interface each to the leading end faces on the first to second housings and flanged further housings thereto is provided. Thereby, an almost continuous and parallel arrangement of the first and second housings in the extension of the busbar strand is possible, and a combination of movement through the drive device can be performed on each side surface. The drive device can for example be positioned in a fixed position on the housing, whereby the kinematic chain can be pre-assembled. Accordingly, the construction of the power transmission device is simplified through pre-assembly of the drive device on the housing.

According to a further preferred embodiment, the first and/or second housings can be formed in a manner that is distributed asymmetrically on each control panel with respect to their fixing.

In addition to the symmetrical configuration of the housing, an asymmetrical configuration of the housing can also be provided. Even more preferably, only the first housing, or only the second housing can be formed asymmetrically, whereas the second housing to the first housing are formed symmetrically. In this case, the axis of symmetry of the housing is related to the position of the stitch diverging from the busbar strand and directed towards the control panel. For example, the first housing and the second housing may each be a so-called T-shaped housing, and such a housing includes interfaces of the first to second housings on ends of a cross bar of a “T”, respectively. A connection part of the T-shaped housing to each control panel may be disposed on the base of the T-shaped housing to form stitches. Starting from the base of the T-shaped housing and through the asymmetric distribution of the crossbars, different spacing distances between the interfaces of the first to second housings within the extension of the busbar strand can be achieved. For example, the distance between the interfaces of the asymmetric T-shaped crossbar may be larger than the distance of the symmetrical housing configured as a T-shaped, in this case, the T-bar is distributed symmetrically with respect to the base of the T-shaped housing. do. Regardless of the symmetrical or asymmetrical configuration of the first to second housings, the T-shaped base must have an unchanging depth, thereby making its interfaces in the direction of the transverse axis of the busbar strands and the perfection of symmetrical and asymmetrical housings. Connection becomes possible.

Also, in a preferred manner, the first control panel and the second control panel, in which the spacing between themselves is achieved through the busbar strands, can form a group, and the groups of control panels are adjacent to different groups. The spacing between the control panels is connected in a way that is smaller than the spacing between adjacent control panels of a group.

Through the use of the first control panel and the second control panel, and the grouping of these control panels, one module is formed that facilitates the use of an integer number of control panels on the power transmission device. Thus, between the control panels of one module, an enlarged spacing is provided compared to adjacent control panels of different groups. Thus, it is possible to provide a chamber between the control panels within a group, in order to position, for example, operating elements, measuring devices, etc., and to enable access between successive control panels in the shape of a comb of the power transmission device. have. Control of one group, for example, by forcing the arm of one of the housings to be too long to the adjacent one of the busbar strands to form the distance of the stitch of the busbar strand and thus the upper conductor of the control panels. The spacing of the panels can be achieved through the use of an asymmetric housing.

Further, preferably, the second busbar strand may be disposed substantially in parallel with respect to the first busbar strand, and the first housing is disposed in the first busbar strand on the first control panel, and the second busbar strand A second housing is disposed therein, and a second housing is disposed in the first busbar strand on the second control panel, and the first housing is disposed in the second busbar strand.

In addition to the use of the first busbar strand, the second busbar strand can also be used in the power transmission device. Accordingly, for example, control panels located spaced apart from each other in the extension of the busbar strand can be connected via one busbar strand among busbar strands, and additional control via the other busbar strand among busbar strands The panels are connected. From now on, if several discrete interfaces are arranged on the first and second housings not only within the first busbar strand, but also within the second busbar strand, the alternating arrangement between the two busbar strands is mutually It can be done in an offset manner. One first and one second housing may be connected to the same control panel, respectively. Accordingly, even when the configuration of the busbar strands extending in the direction of the transverse axis is of the same type, an offset between the first housings and the second housings within the busbar strands can be achieved. Thus, within one group of control panels, the same housings can be arranged in each diagonal or transverse direction. In this case, in particular, when using asymmetric housings, an asymmetric alignment with opposite direction signs can be performed within the two busbar strands.

In a preferred manner, the drive devices arranged on the side surfaces on the housings of the first and second busbar strands can be oriented towards each other.

The drives of the two busbar strands can be oriented towards each other. In this way, for example, when the busbar strands are installed in substantially parallel, the driving device can be positioned in a manner defined by the busbar strands. In this way, on the one hand, on the busbar strands, a central operability or driveability is provided, and on the other hand, the drive units facing each other are given mechanical protection via the busbar strands. In particular, when the alternately arranged first housings and the second housings are aligned in antiparallel, in order to protrude the driving devices of each of the two busbar strands toward each other, through antiparallel alignment of the asymmetrical housings. The same basic housing can be used.

Further, in a preferred manner, the drive devices arranged on the side surfaces on the housings of one control panel can be arranged substantially without offset from one another in the direction of the extension of the busbars.

The offset-free alignment of the drive units allows spatial allocation of the drives to each control panel, the drive units manipulating the stitches of the two busbar strands of the same control panel are arranged substantially in line with each other. Through the omission of the offset in the transverse direction, the individual housings in the extension of the busbar strands can each be arranged alternately with each other, and in front of each control panel each the same type of alignment of the drive devices is achieved. The drive devices can be aligned symmetrically, respectively, with respect to the base of the housing (a connection facing towards the control panel).

In the following, an embodiment of the invention is schematically illustrated in the drawings and described in more detail below.

1 is a perspective view of a power transmission device.
2 is a front view of the power transmission device as seen in FIG. 1.

The power transmission device comprises a first busbar strand (1) and a second busbar strand (2). The first busbar strand 1 and the second busbar strand 2 extend substantially parallel to each other and parallel to the transverse axis 3 (transverse direction). The first busbar strand 1 as well as the second busbar strand 2 also comprise a side-by-side arrangement between the first housings 4 and the second housings 5. The first housings 4 and the second housings 5 are each alternately in the extension of the first busbar strand 1 and alternately in the extension of the second busbar strand 2, respectively. Is placed. In this case, the sequence of the housings 4 and 5 starts with the first housing 4 in the first busbar strand 1 and an alternating sequence of the second and first housings 5 and 4 On the other hand, in the second busbar strand 2, an alternating sequence of the first and second housings 4, 5 starting with the second housing 5 is performed in the direction of the horizontal axis 3 It is divided into. In Fig. 1, the interfaces located at the end sides on the first to second housings 4 and 5 at the corresponding position are shown in a state that is not assigned, respectively. Correspondingly, in the extension of the transverse axis 3 in the leading section, further first to second housings 4, 5 can still be connected in the busbar strands 1, 2, while providing a power transmission device. Can be expanded.

The first to second housings 4 and 5 are each formed as T-shaped housings, and the base (connections facing each of the control panels 6, 7, 8, 9, 10, 11) are the first and second housings. 2 The housings 4, 5 and the corresponding first to second busbar strands 1, 2 are each fixed on one control panel 6, 7, 8, 9, 10, 11 and this control panel From (6, 7, 8, 9, 10, 11) are formed as connecting sleeves, respectively, to form one stitch each towards the upper conductors of the two busbar strands (1, 2). (Not shown in Figures 1 and 2).

One control panel 6, 7, 8, 9, 10, 11 is assigned to each of the two housings 4 and 5 of the first to second busbar strands 1 and 2, respectively, and this control Bases of the first to second housings 4 and 5 are fixed on the panel, respectively. Thus, here, the first control panel 6, the second control panel 7, the third control panel 8, the fourth control panel 9, the fifth control panel 10, and the sixth control panel 11 ) Are arranged substantially parallel to the depth axis 12 within the extension of the transverse axis 3, whereby the individual control panels 6, 7, 8, 9, 10, 11 are arranged in a comb shape Two busbar strands 1 and 2 are formed. The control panels 6, 7, 8, 9, 10 and 11 are each of substantially the same type. Each of the control panels includes an encapsulated housing configured as a single member or multiple members. In the encapsulation housing, substantially one power switch is arranged. In addition, in order to be able to implement the grounding of the individual phase conductors inside each control panel 6, 7, 8, 9, 10, 11, one supply cut-off switch and a supply of various grounding switches each are provided. From the front, in parallel to the first and second busbar strands 1 and 2, the on-site control cabinets 13 are fixed on the control panels 6, 7, 8, 9, 10, 11 respectively .

Each of the two control panels 6, 7, 8, 9, 10, 11 forms one group, the first and second control panels 6, 7 form a first group 14, The third and fourth control panels 8 and 9 form a second group 15, and the fifth and sixth control panels 10 and 11 form a third group 16. The groups 14, 15, 16 of the control panels 6, 7, 8, 9, 10, 11 are aligned parallel to each other. In this case, the separation distance between the control panels 6, 7, 8, 9, 10, 11 inside one group 14, 15, 16 is adjacent to the control panels of several groups 14, 15, 16 Greater than the spacing between (7, 8, 9, 10). Correspondingly, between the respective second control panels 6, 7, 8, 9, 10, 11, the spacing between the control panels 6, 7, 8, 9, 10, 11 is enlarged.

In order to derive the definition of the spacing distances between the control panels 6, 7, 8, 9, 10, 11, the first housings and the second housings 5 are each in the form of flanges 17 on the front end. Includes human interfaces. The interfaces or flanges 17 are arranged on the sides oriented in the opposite direction of the first to second housings 4 and 5. On each of the housings 4 and 5, the flanges at the corresponding positions are aligned in opposite directions to each other. In this case, the flange planes 17 are aligned substantially perpendicular to the transverse axis 3 and parallel to each other. In the first to second housings 4 and 5, the phase conductors are insulated with multiple poles, respectively. In addition, cut-off switches are arranged as electrical switching devices inside the first and second housings (4, 5), respectively, by these cut-off switches, starting from two busbar strands (1, 2) and controlling various Stitches of the phase conductors facing the panels 6, 7, 8, 9, 10, 11 may be blocked. Thus, the first and second housings 4 and 5 are housings 4 and 5 having the same function. In order to operate the switching contact pieces that can be moved relative to each other of the cut-off switches within the first and second housings 4 and 5, the driving devices 18 are each provided with the first to second housings ( 4, 5) are positioned on the side surface. In this case, the driving devices 18 of the first and second housings 4 and 5, each assigned to one common control panel 6, 7, 8, 9, 10, 11, are facing each other, Thereby the driving devices 18 protrude into the chamber located between the first busbar strand 1 and the second busbar strand 2. In this case, the driving devices 18 of one control panel 6, 7, 8, 9, 10, 11 are substantially the same plane on each of the control panels 6, 7, 8, 9, 10, 11 In other words, they are aligned without offset along the transverse axis 3. Thus, a mechanically protected chamber is formed between the busbar strands 1 and 2, and the driving devices 18 can be accommodated inside this chamber. Thus, mechanical protection is provided on the one hand, and a space-saving arrangement of the drive devices 18 is also provided on the other hand. Through the front surfaces of the drive devices 18, the manipulation or indication of the switching state of the cut-off switches can be performed in the field.

In FIG. 2, a schematic front view of a power transmission device as can be seen in FIG. 1 is shown. Unlike the drawing of FIG. 1, here, the closing of the first to second busbar strands 12 using blind covers 19 is shown. Here, perpendicular to the drawing plane (2), the stitches of the phase conductors of the busbar strands (1, 2) are shown symbolically with respect to the contours, respectively, and partially through the busbar strands (1, 2). It extends toward the control panels 6, 7, 8, 9, 10, 11 that are concealed. Further, perpendicular to the drawing plane, the base of the T-shaped first to second housings 4 and 5 also extends. The first housings 4 comprise, in relation to the base, respective crossbars of the letter "T" which are also located on the interfaces or flanges 17 for connection with the additional housings 4 and 5 Formed symmetrically. The extension of the first housings 4 in the direction of the transverse axis 3 substantially corresponds to the width of the control panels 6, 7, 8, 9, 10, 11 in the direction of the transverse axis 3. The second housings 5, unlike the first housings 4, are formed asymmetrically with respect to the division of the crossbar of the letter "T". Also, the distance between the interfaces/flanges 17 on the first housing 4 is smaller than the distance between the interfaces/flanges 17 on the second housing 5. Additionally, the second housing 5 is formed asymmetrically with respect to the position of the base (stitch line). In other words, with respect to the fixing on each of the control panels 6, 7, 8, 9, 10, 11, the interfaces of the second housing 5 (flanges 17) are not equally spaced apart. have. In doing so, the second housings 5 are formed as asymmetric T-shaped housings. Arrangements of the first housing 4 and the second housing 5 are alternately provided in the extension portions of the first to second busbar strands 1 and 2, respectively. Based on the asymmetry of the second housing 5, between the respective second control panels 6, 7, 8, 9, 10, 11, the control panels 6, 7, 8, 9, 10, 11), a larger separation distance is formed between the control panels. Correspondingly, groups 14, 15, 16 of the control panels 6, 7, 8, 9, 10, 11 are formed, and within each group 14, 15, 16, each of several groups More between the respective control panels 6, 7, 8, 9, 10, 11 than between the respective adjacent control panels 6, 7, 8, 9, 10, 11 of (14, 15, 16) There is a large separation gap.

In Fig. 2 an alternating sequence of second and first housings 5, 4 starting with the first housing 4 in the first busbar strand 1 is provided, while the second busbar strand ( 2) In a manner in which an alternating sequence of the first and second housings 4, 5 is provided starting with the second housing 5 within, the second busbar as well as within the first busbar strand 1 It is shown that an alternating sequence of the first housings 4 and the second housings 5 is formed even within the strand 2. Thus, inside one group 14, 15, 16, the asymmetric arms of the second housing 5 with different direction signs in the first and second busbar strands 1, 2 respectively In 15, 16) the state of bridging the enlarged spacing of the control panels 6, 7, 8, 9, 10, 11 is achieved. Through the opposite alignment of the asymmetrical second housings 5, the side surfaces of each of the first and second housings 4, 5 on each control panel 6, 7, 8, 9, 10, 11 The driving devices 18 arranged on the surface face each other, and the driving devices (with no offset from each other) in the direction of the transverse axis 3 on each control panel 6, 7, 8, 9, 10, 11 To align 18), the same housing body can be used.

If necessary, for example, a division can be inserted in the flange joints between the respective flanges 17. 1 and 2, disc-shaped insulators that separate the fluid receiving chambers of the first and second housings from each other are disposed between the flanges 17, respectively.
