在端子裝置20設置有：連接有來自送電系 統之拉入線的一次側端子21a、21b、21c、21d；及連接有需求家側配線之二次側端子22a、22b、22c、22d。 The terminal device 20 is provided with: a connection from the power transmission system The primary side terminals 21a, 21b, 21c, and 21d of the pull-in line are connected to the secondary side terminals 22a, 22b, 22c, and 22d to which the home side wiring is required.
再者，一次側端子21a、21b、21c係在電量計本體10內，透過導體板12a、12b、12c與開閉繼電器14之繼電器端子15a、15b、15c連接。 Further, the primary side terminals 21a, 21b, and 21c are connected to the relay terminals 15a, 15b, and 15c of the opening and closing relay 14 through the conductor plates 12a, 12b, and 12c in the fuel gauge main body 10.
同樣地，二次側端子22a、22b、22c係在電量計本體10內，藉由導體板13a、13b、13c而貫通變流器11a、11b、11c之內部而連接在繼電器端子16a、16b、16c。 Similarly, the secondary terminals 22a, 22b, and 22c are connected to the relay terminals 16a and 16b via the conductor plates 13a, 13b, and 13c through the inside of the current transformers 13a, 11b, and 13c. 16c.
一次側端子21d係連接有N相，因此在端子裝置20之內部藉由短路棒17而連接在二次側端子22d。 Since the primary side terminal 21d is connected to the N phase, the terminal device 20 is connected to the secondary side terminal 22d by the shorting bar 17.
端子裝置20係一體地設置成構成電量計本體10之底部。 The terminal device 20 is integrally provided to constitute the bottom of the fuel gauge body 10.
端子裝置20係具有端子台23，該端子台23係對應一次側端子21a、21b、21c、21d、及二次側端子22a、22b、22c、22d之數量而在一端具有供電線插入之電線插入孔24，且在另一端具有與電線插入孔24相對向而供金屬板29插入的上部及下部固定孔25、26。此外，端子台23係藉由合成樹脂等絕緣材而形成為橫長狀，且設置間隔壁，以使各相之一次側端子及二次側端子間分離。 The terminal device 20 has a terminal block 23 which is inserted into a wire having a power supply line insertion at one end corresponding to the number of the primary side terminals 21a, 21b, 21c, 21d and the secondary side terminals 22a, 22b, 22c, 22d. The hole 24 has the upper and lower fixing holes 25, 26 which are opposed to the wire insertion hole 24 at the other end and into which the metal plate 29 is inserted. Further, the terminal block 23 is formed in a horizontally long shape by an insulating material such as synthetic resin, and a partition wall is provided to separate the primary side terminal and the secondary side terminal of each phase.
端子台23係在電線插入孔24與上部及下部固定孔25、26之間，朝與電線插入孔24及上部及下部固定孔25、26正交之上下方向以可移動之方式收容保持具有中空之長方形剖面的端子金具27，在端子金具27之上部，安裝有2個固定用螺絲28。 The terminal block 23 is movably accommodated and held between the electric wire insertion hole 24 and the upper and lower fixing holes 25 and 26 so as to be orthogonal to the electric wire insertion hole 24 and the upper and lower fixing holes 25 and 26. The terminal fittings 27 of the rectangular cross section are attached to the upper part of the terminal fitting 27, and two fixing screws 28 are attached.
該等固定用螺絲28係藉由鎖緊而進入端子金具27之中空的內部，藉由放鬆而後退。 These fixing screws 28 are locked into the hollow interior of the terminal fitting 27, and are retracted by being relaxed.
金屬板29係如後所述插入於上部固定孔25或下部固定孔26，且固定在端子台23。 The metal plate 29 is inserted into the upper fixing hole 25 or the lower fixing hole 26 as will be described later, and is fixed to the terminal block 23.
金屬板29對於端子台23之固定，係藉由例如對上部固定孔25或下部固定孔26之壓入或未圖示之螺絲而進行。 The fixing of the metal plate 29 to the terminal block 23 is performed by, for example, pressing or unillustrated screws on the upper fixing hole 25 or the lower fixing hole 26.
在金屬板29之前端，分別安裝有導體板12a至12b、13a至13c，兩者係以導體板固定螺絲30來固定。 At the front end of the metal plate 29, conductor plates 12a to 12b, 13a to 13c are respectively attached, and both are fixed by the conductor plate fixing screws 30.
導體板13a、13b、13c通過變流器11a、11b、11c的內部而固定於開閉繼電器14。 The conductor plates 13a, 13b, and 13c are fixed to the opening and closing relay 14 through the inside of the current transformers 11a, 11b, and 11c.
與一次側端子21d及二次側端子22d對應的金屬板29不連接開閉繼電器14，而是藉由短路棒17短路。 The metal plate 29 corresponding to the primary side terminal 21d and the secondary side terminal 22d is not connected to the opening and closing relay 14, but is short-circuited by the shorting bar 17.
如第2、3圖所示，上部及下部固定孔25、26係以對應於端子金具27之上下移動方向的方式隔著預定間隔而形成在端子台23，且設置達對應於各相之一次側端子與二次側端子之數量的個數。 As shown in FIGS. 2 and 3, the upper and lower fixing holes 25 and 26 are formed on the terminal block 23 at predetermined intervals so as to correspond to the upper and lower moving directions of the terminal fittings 27, and are disposed once corresponding to the respective phases. The number of the number of side terminals and secondary side terminals.
在此，如第4圖所示，當將金屬板29插入於端子台23之下部固定孔26時，如第5、6圖所示，端子金具27係使下表面夾持於端子台23之底面與金屬板29而固定。 Here, as shown in FIG. 4, when the metal plate 29 is inserted into the lower fixing hole 26 of the terminal block 23, as shown in FIGS. 5 and 6, the terminal fitting 27 holds the lower surface of the terminal block 23 The bottom surface is fixed to the metal plate 29.
亦即，當將電線18插入於端子裝置20之電線插入孔24並鎖緊固定用螺絲28而使之下降時，電線18係被夾持並固定在金屬板29之上表面與固定用螺絲28之下端部。 That is, when the electric wire 18 is inserted into the electric wire insertion hole 24 of the terminal device 20 and the fixing screw 28 is locked and lowered, the electric wire 18 is clamped and fixed to the upper surface of the metal plate 29 and the fixing screw 28 Below the end.
亦即，實現與以往之螺絲固定方式同樣之電線固定方 法。 That is, the same wire fixing method as the conventional screw fixing method is realized. law.
此時，連接在金屬板29之導體板13b係如第6圖所示設置有朝上下方向位移之曲柄，導體板13b係在與電量計本體10之底面分離達距離L之位置貫通變流器11b後，朝下方向位移，且藉由導體板固定螺絲30而與插入於下部固定孔26之金屬板29固定。 At this time, the conductor plate 13b connected to the metal plate 29 is provided with a crank that is displaced in the up-and-down direction as shown in Fig. 6, and the conductor plate 13b is separated from the bottom surface of the fuel gauge body 10 by a distance L to pass through the converter. After 11b, it is displaced downward, and is fixed to the metal plate 29 inserted into the lower fixing hole 26 by the conductor plate fixing screw 30.
依據本實施形態，藉由將同樣之電線固定方法實施在端子裝置20之各相，使用本發明之電量計即可對應於螺絲固定方式之電線固定方法。 According to the present embodiment, the same electric wire fixing method can be applied to each phase of the terminal device 20, and the electric energy meter of the present invention can be used in accordance with the wire fixing method of the screw fixing method.
另一方面，如第7圖所示，當將金屬板29插入於端子台23之上部固定孔25時，如第8、9圖所示，端子金具27係在內面不接觸金屬板29之範圍內可朝上下動作。 On the other hand, as shown in Fig. 7, when the metal plate 29 is inserted into the upper fixing hole 25 of the terminal block 23, as shown in Figs. 8 and 9, the terminal fitting 27 is not in contact with the metal plate 29 on the inner surface. It can move up and down within the range.
當將電線18插入於端子台23之電線插入孔24並鎖緊固定用螺絲28時，端子金具27係處於可朝上下動作之狀態，因此在藉由鎖緊固定用螺絲28而與金屬板29接觸後，端子金具27會對應於固定用螺絲之鎖緊量而上升。 When the electric wire 18 is inserted into the electric wire insertion hole 24 of the terminal block 23 and the fixing screw 28 is locked, the terminal fitting 27 is in a state in which it can be moved up and down, and therefore the metal plate 29 is locked by the fixing fixing screw 28. After the contact, the terminal fitting 27 rises corresponding to the locking amount of the fixing screw.
因此，電線18係如第8圖所示夾持並固定在金屬板29之下表面與端子金具27之底面。 Therefore, the electric wire 18 is clamped and fixed to the lower surface of the metal plate 29 and the bottom surface of the terminal fitting 27 as shown in Fig. 8.
因此，在此情形下，實現與習知之衝壓螺旋方式同樣之電線固定方法。 Therefore, in this case, the same wire fixing method as the conventional punching spiral method is realized.
在此情形下，如第9圖所示使導體板13b之上下與第6圖之情形相反，亦即，導體板13b係在與電量計本體10之底面分離達距離L之位置貫通變流器11b 後，朝上方向位移，且藉由導體板固定螺絲30而與插入於上部固定孔25之金屬板29固定。 In this case, as shown in Fig. 9, the upper and lower sides of the conductor plate 13b are opposite to those of the sixth embodiment, that is, the conductor plate 13b is separated from the bottom surface of the fuel gauge body 10 by a distance L to pass through the converter. 11b Then, it is displaced upward, and is fixed to the metal plate 29 inserted into the upper fixing hole 25 by the conductor plate fixing screw 30.
如此方式，即使金屬板29插入於上部固定孔25或下部固定孔26之任一者，導體板13b亦可藉由曲柄而使變流器11b在與電量計本體10之底面分離達距離L之位置貫通。 In this manner, even if the metal plate 29 is inserted into either the upper fixing hole 25 or the lower fixing hole 26, the conductor plate 13b can be separated from the bottom surface of the fuel gauge body 10 by the crank by a crank to a distance L. The location is continuous.
由利用第6、9圖之說明得知，導體板13b之曲柄之位移量係依據上部及下部固定孔25、26間之距離與距離L之關係而決定者。 As is apparent from the description of Figs. 6 and 9, the displacement amount of the crank of the conductor plate 13b is determined by the relationship between the distance between the upper and lower fixing holes 25 and 26 and the distance L.
依據本實施形態，藉由將上述之電線固定方法實施在端子裝置20之各相，即可對應於螺絲固定方式或衝壓螺旋方式。 According to the present embodiment, the wire fixing method described above can be applied to each phase of the terminal device 20, and can be screw-fixed or punched.
再者，由於在分別貫通變流器11a、11b、11c之導體板13a、13b、13c設置有對應於端子裝置20之上部及下部固定孔25、26之間隔而朝上下方向位移之曲柄，因此即使將金屬板29插入於端子台23之上部固定孔25、下部固定孔26之任一者，導體板13a、13b、13c之位置亦不會相對於變流器11a、11b、11c而改變，因此可使變流器之電流測量精確度提升 Further, since the conductor plates 13a, 13b, and 13c that respectively pass through the current transformers 11a, 11b, and 11c are provided with cranks that are displaced in the vertical direction in accordance with the interval between the upper portion and the lower fixing holes 25 and 26 of the terminal device 20, Even if the metal plate 29 is inserted into any of the upper fixing hole 25 and the lower fixing hole 26 of the terminal block 23, the positions of the conductor plates 13a, 13b, and 13c are not changed with respect to the current transformers 11a, 11b, and 11c. Therefore, the current measurement accuracy of the converter can be improved.
此外，本發明係在本發明之範圍內，可自由地組合各實施形態，或可適當地將各實施形態予以變更或省略。 Further, the present invention is within the scope of the invention, and the embodiments may be freely combined, or the embodiments may be modified or omitted as appropriate.
