図2は従来の金属閉鎖形スイッチギヤの一例を示すもので、(A)は正面図、 (B)は側面図である。 図において、前面が開口する箱体10の前面側の側面には、扉9が蝶番11に より取付けられる。ハンドル6は扉9に取付けられ、ハンドル6を操作すること により、扉9が開閉される。箱体10内には、収納枠5が固定される。収納枠5 には、固定接触部4aおよび4bが取付けられる。固定接触部4aには変流器1 3が主回路導体15aにより接続され、固定接触部4bには零相変流器14が主 回路導体15bにより接続される。固定接触部4a,4bにそれぞれ接離する断 路形接触部1a,1bを有する遮断器等の引出形開閉器2は、収納枠5に収納あ るいは引出しされる。 扉9の正面側には、操作スイッチ、計測装置および保護装置等の監視装置7が 取付けられるとともに、監視装置7の試験をするための試験用端子8が取付けら れる。監視装置7および試験用端子8と引出形開閉器2とは、制御用電線12に より接続される。 2A and 2B show an example of a conventional metal-closed switchgear, in which FIG. 2A is a front view and FIG. 2B is a side view. In the figure, a door 9 is attached by a hinge 11 to the side surface on the front surface side of the box body 10 whose front surface is open. The handle 6 is attached to the door 9, and the door 9 is opened and closed by operating the handle 6. The storage frame 5 is fixed in the box 10. Fixed contact portions 4a and 4b are attached to the storage frame 5. The current transformer 13 is connected to the fixed contact portion 4a by the main circuit conductor 15a, and the zero-phase current transformer 14 is connected to the fixed contact portion 4b by the main circuit conductor 15b. The drawer type switch 2 such as a circuit breaker having the disconnecting contact portions 1a and 1b that come into contact with and separate from the fixed contact portions 4a and 4b, respectively, is stored in the storage frame 5 or pulled out. On the front side of the door 9, a monitoring device 7 such as an operation switch, a measuring device and a protective device is attached, and a test terminal 8 for testing the monitoring device 7 is attached. The monitoring device 7, the test terminal 8 and the drawer type switch 2 are connected by a control wire 12.
【0003】 上記従来の金属閉鎖形スイッチギヤにおいては、図2に示すように、引出形開 閉器2が収納枠5に収納された状態では、断路形接触部1a,1bが固定接触部 4a,4bにそれぞれ接触して、金属閉鎖形スイッチギヤが運転中である。試験 等を行う場合には、ハンドル6を操作して、扉9を開放する。次に、引出形開閉 器2を収納枠5内から引出せば、断路形接触部1a,1bが固定接触部4a,4 bからそれぞれ離脱して、引出形開閉器2は断路位置となる。この状態で、試験 用端子8を使用して、監視装置7の必要な試験を行う。 なお、試験終了後は、上記引出し操作と逆の操作を行って、引出形開閉器2を 収納枠5内に収納する。In the above-mentioned conventional metal-closed switchgear, as shown in FIG. 2, when the drawer-type opener 2 is housed in the housing frame 5, the disconnect type contact parts 1a and 1b are fixed contact parts 4a. , 4b, respectively, and the metal closed switchgear is in operation. When performing a test or the like, the handle 6 is operated to open the door 9. Next, when the pullout switch 2 is pulled out from the storage frame 5, the disconnection type contact portions 1a and 1b are separated from the fixed contact portions 4a and 4b, respectively, and the pullout type switch 2 is in the disconnection position. In this state, the test terminal 8 is used to perform a necessary test of the monitoring device 7. After the test is completed, the drawer type switch 2 is housed in the housing frame 5 by performing the reverse operation to the above drawer operation.
【0004】[0004]
上記従来の金属閉鎖形スイッチギヤにおいては、引出形開閉器2は、運転中は 運転位置にあり、試験等を行う時に断路位置にあるが、試験後に運転位置にもど し忘れることがある。しかも、扉9を閉めた状態では、運転位置であるか、断路 位置であるかは確認できない。 また、変流器13および零相変流器14の点検を行う場合、箱体10内に人が 入って行う必要がある。 In the conventional metal-closed switchgear described above, the pull-out switch 2 is in the operating position during operation and is in the disconnection position when performing a test or the like, but it may be forgotten to return to the operating position after the test. Moreover, with the door 9 closed, it is not possible to confirm whether it is the operating position or the disconnecting position. In addition, when inspecting the current transformer 13 and the zero-phase current transformer 14, it is necessary for a person to enter the box body 10.
【0005】 さらに、扉9を開けるために開く側にスペースが必要となり、設置場所に苦慮 している。 また、監視装置7が扉9に取付けられ、引出形開閉器2は収納枠5に収納され ているため、これらを電気的に接続しなければならず、扉9から引出形開閉器2 まで制御用電線12が必要である。 そこで本考案は、引出形開閉器の運転あるいは断路状態を外部から容易に確認 でき、かつ変流器および零相変流器の点検あるいは取替を容易に行うことができ 、しかも扉の開閉スペースの縮小化を図ることを目的とする。Further, a space is required on the opening side to open the door 9, which makes it difficult to install the door 9. Further, since the monitoring device 7 is attached to the door 9 and the drawer type switch 2 is housed in the storage frame 5, these must be electrically connected, and control is performed from the door 9 to the drawer type switch 2. The electric wire 12 is required. Therefore, the present invention makes it possible to easily confirm the operation or disconnection state of the drawer type switch from the outside, and to easily inspect or replace the current transformer and zero-phase current transformer, and also to open and close the door. The purpose is to reduce the size of.
【0006】[0006]
前面が開口する箱体内に、二つの固定接触部が取付けられた収納枠を固定する 。変流器あるいは零相変流器をそれぞれ備えるとともに、前記固定接触部にそれ ぞれ接離する二つの断路形接触部を有し、かつ監視装置およびこの監視装置の試 験をするための試験用端子が正面側に取付けられた引出形開閉器を設ける。この 引出形開閉器は前記収納枠に収納されたときに、前記箱体の前面を閉鎖するよう に形成する。 In the box with the front opening, fix the storage frame with two fixed contact parts attached. A tester equipped with a current transformer or a zero-phase current transformer, and having two disconnecting contact parts that come in contact with and separate from the fixed contact part, and a test device and a test for testing this monitor device.

【0007】[0007]
変流器および零相変流器と、監視装置および試験用端子とが引出形開閉器に搭 載されるため、制御用電線が不要となる。運転位置では引出形開閉器が箱体の前 面を閉鎖し、かつ断路位置では引出形開閉器が箱体の前面から突出するので、扉 が不要となるとともに、運転位置にあるのか断路位置にあるのかを容易に確認で きる。 また、変流器および零相変流器は引出形開閉器に搭載されているので、引出形 開閉器を引出せば、点検および取替を容易に行うことができる。 Since the current transformer and zero-phase current transformer, the monitoring device and the test terminal are mounted on the drawer type switch, the control wire is not required. In the operating position, the drawer type switch closes the front surface of the box body, and in the disconnection position, the drawer type switch protrudes from the front surface of the box body.Therefore, no door is required, and it is in the operating position or in the disconnection position. You can easily check if there is. Moreover, since the current transformer and the zero-phase current transformer are mounted on the drawer type switch, inspection and replacement can be easily performed by pulling out the drawer type switch.

図1は本考案の金属閉鎖形スイッチギヤの一実施例を示すもので、(A)は正 面図、(B)は側面図である。 図において、前面が開口する箱体20内には、固定接触部4aおよび4bが取 付けられた収納枠5が固定される。引出形開閉器22の箱体20内側には、固定 接触部4a,4bにそれぞれ接離する断路形接触部11a,11bがそれぞれ取 付けられる。断路形接触部11aには変流器23が搭載され、断路形接触部11 bには零相変流器24が搭載される。引出形開閉器22の正面側には、監視装置 7、試験用端子8およびハンドル16が取付けられる。また、引出形開閉器22 は、運転中すなわち収納枠5に収納されたときには、箱体20の前面を閉鎖し、 かつ断路位置すなわち収納枠5から引出されたときには、箱体20の前面から突 出するように形成される。 1A and 1B show an embodiment of a metal-closed switchgear according to the present invention. FIG. 1A is a front view and FIG. 1B is a side view. In the figure, a storage frame 5 to which fixed contact portions 4a and 4b are attached is fixed in a box body 20 having an open front surface. On the inside of the box body 20 of the drawer type switch 22, the disconnect type contact parts 11a and 11b are respectively attached to and separated from the fixed contact parts 4a and 4b. A current transformer 23 is mounted on the disconnecting contact portion 11a, and a zero-phase current transformer 24 is mounted on the disconnecting contact portion 11b. A monitoring device 7, a test terminal 8 and a handle 16 are attached to the front side of the drawer type switch 22. Further, the drawer type switch 22 closes the front surface of the box body 20 during operation, that is, when it is stored in the storage frame 5, and projects from the front surface of the box body 20 when it is disconnected from the box 20, that is, when it is pulled out from the storage frame 5. Formed to emerge.
【0009】 上記本考案の金属閉鎖形スイッチギヤにおいては、図1に示すように、引出形 開閉器22が収納枠5に収納された状態では、断路形接触部11aおよび11b が固定接触部4aおよび4bにそれぞれ接触して、金属閉鎖形スイッチギヤが運 転中である。また、このとき引出形開閉器22は箱体20の前面を閉鎖している ので、運転中であることを容易に確認することができる。 試験等を行う場合には、ハンドル16を操作して、引出形開閉器22を収納枠 5内から引出せば、断路形接触部11aおよび11bが固定接触部4aおよび4 bから離脱して、引出形開閉器22は断路位置となる。この状態で、試験用端子 8を使用して、監視装置7の必要な試験を行う。また、このとき引出形開閉器2 2は箱体20の前面から突出しているので、断路位置にあることを容易に確認す ることができる。さらに、引出形開閉器22を箱体20内から完全に引出せば、 変流器23および零相変流器24を点検することができる。 なお、試験終了後は、上記引出し操作と逆の操作を行って、引出形開閉器22 を収納枠5内に収納する。In the metal closed switchgear of the present invention, as shown in FIG. 1, when the drawer type switch 22 is housed in the housing frame 5, the disconnect type contact parts 11a and 11b are fixed contact parts 4a. The metal-closed switchgear is in operation by contacting the contact points 4 and 4b, respectively. Further, at this time, the drawer type switch 22 closes the front surface of the box body 20, so that it can be easily confirmed that the vehicle is in operation. When conducting a test or the like, if the handle 16 is operated to pull out the drawer-type switch 22 from the storage frame 5, the disconnection-type contact portions 11a and 11b are separated from the fixed contact portions 4a and 4b and pulled out. The switch 22 is in the disconnecting position. In this state, the test terminal 8 is used to perform a necessary test of the monitoring device 7. Further, at this time, since the drawer-type switch 22 projects from the front surface of the box body 20, it can be easily confirmed that it is in the disconnection position. Further, if the pull-out switch 22 is completely pulled out from the inside of the box body 20, the current transformer 23 and the zero-phase current transformer 24 can be inspected. After the test is completed, the drawer type switch 22 is housed in the housing frame 5 by performing the reverse operation to the above drawer operation.
