Description

【考案の詳細な説明】[Detailed description of the device]

【0001】[0001]

【産業上の利用分野】[Industrial applications]

本考案は、遮断器等の開閉装置を駆動する操作機構に関するものである。 The present invention relates to an operating mechanism that drives a switchgear such as a circuit breaker.

【0002】[0002]

【従来の技術】[Prior Art]

遮断器等の開閉装置は近年技術開発が進み、遮断部については真空中あるいは SF6ガス中に密封されたものが増加しており、信頼性の向上およびメンテナン スの省略が図られている。 The technological development of switchgear such as circuit breakers has progressed in recent years, and the number of circuit breakers sealed in vacuum or SF6 gas is increasing, which is aimed at improving reliability and omitting maintenance.

【0003】 一方、その遮断部を駆動するための操作機構には、一般に潤滑および防錆を兼 ねて、その操作リンク類にグリスが塗布されるが、操作機構は気中に置かれる場 合が多いため、空気中の塵埃によるグリスの汚損劣化あるいは酸化劣化が免れな い。このために、3年あるいは6年毎にグリスアップを含めた点検を必要として いる。これに対し、最近保守要員不足等の理由から、点検周期の長期化の要求、 更には完全なメンテナンスフリー化の要求が高まってきている。On the other hand, the operating mechanism for driving the shut-off portion is generally coated with grease for both lubrication and rust prevention, but the operating mechanism is placed in the air. Therefore, it is inevitable that grease in the air will be contaminated or deteriorated due to dust in the air. For this reason, it is necessary to inspect every 3 or 6 years, including grease up. On the other hand, recently, due to a shortage of maintenance personnel and the like, there is an increasing demand for a longer inspection cycle and a complete maintenance-free requirement.

【0004】 従来の開閉装置の操作機構においても、グリスに起因する不具合を解消するた めに、鎖錠ピンおよび引外しハッカの表面に、耐磨耗性の優れたTiNのセラミ ックコーティングを施すことにより、当該部分のグリス塗布を不要としたものが 実用化されている。Even in the conventional operating mechanism of the opening / closing device, in order to eliminate the trouble caused by grease, the surface of the locking pin and the tripping hacker is coated with TiN ceramic coating having excellent wear resistance. It has been put into practical use that the application of grease is not required by applying it.

【0005】 その一例を図4を用いて説明する。操作機構の詳細については後述するが、図 は、ガス遮断部の投入状態における操作機構の鎖錠ピン9と引外しハッカ16と の関係を示している。投入状態では、図のように鎖錠ピン9は復帰ばね10によ り時計方向に回転しようとする力を受けており、引外しハッカ16が反時計方向 に回転するのを止めている。An example thereof will be described with reference to FIG. Although the details of the operating mechanism will be described later, the figure shows the relationship between the locking pin 9 and the tripping hacker 16 of the operating mechanism in the closed state of the gas blocking portion. In the closed state, as shown in the figure, the locking pin 9 receives a force to rotate in the clockwise direction by the return spring 10, and stops the tripping hacker 16 from rotating in the counterclockwise direction.

【0006】 引外し指令が出ると、引外しコイル7が励磁され、引外しプランジャ8を吸引 し、引外しレバー17を時計方向に回転させる。これにより鎖錠レバー18が反 時計方向に回転し、引外しハッカ16と鎖錠ピン9の係合が外れるので、引外し ハッカ16が反時計方向に回転し、遮断ばねにより主軸12が回転し、遮断部が 遮断状態となる。When a trip command is issued, the trip coil 7 is excited, the trip plunger 8 is attracted, and the trip lever 17 is rotated clockwise. As a result, the locking lever 18 rotates counterclockwise and the tripping hacker 16 and the locking pin 9 are disengaged, so the tripping hacker 16 rotates counterclockwise and the main shaft 12 rotates by the shutoff spring. , The shutoff unit is shut off.

【0007】 この鎖錠ピン9は、重要な役目の部品であり、小勢力で動作することを要求さ れる。この部分をグリス潤滑とした場合、定期的にグリスが補給されれば問題は ないが、そうでない場合は、グリスの変質劣化による固着により、鎖錠ピンの復 帰不良等の不具合を発生するケースがあった。そこで、このグリスに起因する不 具合を解消するために、鎖錠ピンおよび引外しハッカの表面に耐磨耗性の優れた TiNのセラミックコーティングを厚さ2〜6μmで施すことにより、当該部分 のグリス塗布を不要とした開閉装置の操作機構が実用化されている。The locking pin 9 is an important component and is required to operate with a small force. If this part is lubricated with grease, there will be no problem if grease is replenished regularly, but if it is not the case, problems such as poor recovery of the locking pin may occur due to sticking due to deterioration and deterioration of grease. was there. Therefore, in order to eliminate the defects caused by this grease, the surface of the lock pin and the tripping hacker is coated with TiN ceramic coating with excellent wear resistance to a thickness of 2 to 6 μm, and An operating mechanism of an opening / closing device that does not require grease application has been put into practical use.

【0008】[0008]

【考案が解決しようとする課題】[Problems to be solved by the device]

この鎖錠ピンは、かかる負荷も軽微であり、回転角度もわずかであるため、T iNコーティングの耐磨耗性のみで十分実用に耐えるものである。しかし、完全 なメンテナンスフリー化の要求に対しては、鎖錠ピン以外の箇所も全てグリスを 使用しない構造とすることが必要である。しかしながら、鎖錠ピン以外の箇所に は耐磨耗性だけでなく低摩擦性も要求されるから、従来用いられてきた耐磨耗性 に優れただけのTiNコーティングでは要求を満足できない。 Since the load applied to this locking pin is light and the rotation angle is small, the wear resistance of the TiN coating is sufficient for practical use. However, in order to meet the requirement of completely maintenance-free, it is necessary to use a structure that does not use grease in all parts other than the locking pin. However, not only the wear resistance but also the low frictional property is required in the parts other than the lock pin, so that the TiN coating which has been conventionally used and has only the excellent wear resistance cannot satisfy the request.

【0009】 本考案は、操作機構にグリスを塗布することなく、長期間に渡り安定した動作 特性を保証することを目的とするものである。An object of the present invention is to guarantee stable operation characteristics for a long period of time without applying grease to the operating mechanism.

【課題を解決するための手段】[Means for Solving the Problems]

本考案は上記目的を達成するために、開閉装置の操作機構において、係合部お よび摺動部を構成する部品の表面に、セラミックコーティングを施した上に、二 硫化モリブデン系の固体潤滑剤の乾燥皮膜をコーティングするものである。 In order to achieve the above-mentioned object, the present invention provides a molybdenum disulfide-based solid lubricant on the surfaces of the parts constituting the engaging part and the sliding part in the operating mechanism of the switchgear, on which ceramic coating is applied. It coats the dry film of.

上記した手段によれば、係合部および摺動部には、操作機構の運転により剥離 し微粒子状となった固体潤滑剤が供給され、長期間にわたって潤滑性が維持され る。 According to the above-mentioned means, the solid lubricant which is separated into fine particles by the operation of the operating mechanism is supplied to the engaging portion and the sliding portion, and the lubricity is maintained for a long period of time.

【0012】[0012]

【実施例】【Example】

本考案を、ガス遮断器の操作機構における投入ハッカとラッチローラの係合部 に適用した例を、図1〜図6を用いて説明する。初めに、ガス遮断器の操作機構 について説明をする。 An example in which the present invention is applied to the engaging portion of the closing hacker and the latch roller in the operation mechanism of the gas circuit breaker will be described with reference to FIGS. First, the operating mechanism of the gas circuit breaker will be described.

【0013】 図2は、ガス遮断器の全体構造を示し、図3は、操作機構2の構造を示し、図 4は、図3の鎖錠ピンの部分を拡大して示している。FIG. 2 shows the overall structure of the gas circuit breaker, FIG. 3 shows the structure of the operating mechanism 2, and FIG. 4 shows the locking pin portion of FIG. 3 in an enlarged manner.

【0014】 ガス遮断器は図2に示すように、車輪付きベース1の上に、操作機構2を前面 に、遮断部3を背面に搭載している。As shown in FIG. 2, the gas circuit breaker includes a wheeled base 1, an operating mechanism 2 on the front side, and a blocking section 3 on the back side.

【0015】 図3に示した操作機構は遮断部を投入した状態にある。投入コイル4により投 入プランジャ5が吸引されて上方に移動し、投入レバー6は時計方向に回り、鎖 錠ピン9によって一体化している引外し自由リンク15と引外しハッカ16を押 し下げて主軸12を回転させ、遮断部3を投入し、遮断ばね11を蓄勢して遮断 動作に備えている。この投入状態では遮断ばね11により主軸12は反対方向に 回転しようとするが、ラッチローラ14と投入ハッカ13の係合によりその力を 受けている。この状態で図4のように、鎖錠ピン9は復帰ばね10により時計方 向に回転しようとする力を受けており、引外しハッカ16が反時計方向に回転す るのを止めている。The operating mechanism shown in FIG. 3 is in a state in which the shutoff portion is closed. The throwing-in coil 4 is attracted by the throwing-in coil 4 and moves upward, and the throwing-in lever 6 rotates in the clockwise direction to push down the trip free link 15 and the tripping hacker 16 which are integrated by the locking pin 9. The main shaft 12 is rotated, the shutoff portion 3 is closed, and the shutoff spring 11 is stored to prepare for the shutoff operation. In this closed state, the main shaft 12 tries to rotate in the opposite direction by the breaking spring 11, but the force is received by the engagement of the latch roller 14 and the closing hacker 13. In this state, as shown in FIG. 4, the locking pin 9 receives a force to rotate clockwise by the return spring 10 and stops the tripping hacker 16 from rotating counterclockwise.

【0016】 引外し指令が出ると、引外しコイル7が励磁され、引外しプランジャ8を吸引 し、引外しレバー17を時計方向に回転させる。これにより鎖錠レバー18が反 時計方向に回転し、引外しハッカ16と鎖錠ピン9の係合が外れるので、引外し ハッカ16が反時計方向に回転し、遮断ばね11により主軸12が回転し、遮断 部3が遮断状態となる。When a trip command is issued, the trip coil 7 is excited, the trip plunger 8 is attracted, and the trip lever 17 is rotated clockwise. As a result, the locking lever 18 rotates counterclockwise and the tripping hacker 16 and the locking pin 9 are disengaged from each other, so that the tripping hacker 16 rotates counterclockwise and the main shaft 12 rotates by the blocking spring 11. Then, the shutoff unit 3 is turned off.

【0017】 次に、本考案を適用した投入ハッカ13とラッチローラ14の係合部について 図1、図5、図6を用いて説明する。図5において、6は投入レバー、14は投 入レバー6に設けられたラッチローラ、13は投入ハッカであり、ラッチローラ 14と投入ハッカ13は係合部Aにおいて係合している。Next, the engaging portion between the input hacker 13 and the latch roller 14 to which the present invention is applied will be described with reference to FIGS. 1, 5 and 6. In FIG. 5, 6 is a closing lever, 14 is a latch roller provided on the dropping lever 6, 13 is a closing hacker, and the latch roller 14 and the closing hacker 13 are engaged at the engaging portion A.

【0018】 このような係合部Aには、高い面圧がかかるため、耐磨耗性と同時に低摩擦性 が必要になる。このため本例においては図6に示すように、投入ハッカ13の表 面に例えばTiNのような耐磨耗性に優れたセラミックコーティングによるコー ティング層19を施す。このコーティング層19は、2〜6μm程度の薄い層で あり、投入ハッカ13の表面仕上げの凹凸に沿う形でコーティングされる。更に その上に、二硫化モリブデン系の固体潤滑剤の乾燥皮膜20をやや厚めにコーテ ィングする。Since a high surface pressure is applied to such an engaging portion A, it is necessary to have abrasion resistance and low friction. For this reason, in this example, as shown in FIG. 6, a coating layer 19 made of a ceramic coating such as TiN having excellent abrasion resistance is applied to the surface of the charging hacker 13. The coating layer 19 is a thin layer having a thickness of about 2 to 6 μm, and is coated along the unevenness of the surface finish of the input hacker 13. Further, a molybdenum disulfide-based solid lubricant dry film 20 is coated on the above layer to a slightly thicker thickness.

【0019】 遮断器の運転に入ると、投入ハッカ13は、ラッチローラ14と摺動接触を繰 り返すことにより、固体潤滑剤の皮膜20の剥離が進み、図1に示すように固体 潤滑剤は本来の細かい粒子21となり、接触面に介在する状態となる。更に運転 時間が経過すると、接触部分の一部、特に突起部は、下層のセラミックコーティ ング層19で接触するようになる。セラミックコーティング層19は耐磨耗性に 優れているため、これ以上乾燥皮膜20の剥離は進まない。この状態が定常状態 となり、接触部分には運転により剥離し微粒子状となった固体潤滑剤21が供給 され、潤滑性が維持される。When the circuit breaker starts to operate, the closing hacker 13 repeats sliding contact with the latch roller 14, whereby the peeling of the solid lubricant film 20 progresses, and as shown in FIG. Becomes the original fine particles 21 and is in a state of interposing on the contact surface. When the operation time further elapses, a part of the contact portion, particularly the protrusion, comes into contact with the lower ceramic coating layer 19. Since the ceramic coating layer 19 has excellent wear resistance, the dry film 20 is not peeled off any more. This state becomes a steady state, and the solid lubricant 21 that has been exfoliated and finely divided by the operation is supplied to the contact portion to maintain the lubricity.

【考案の効果】[Effect of the device]

以上説明した本考案によれば、長期にわたってグリス等の潤滑剤なしで、低摩 擦でかつ耐磨耗性の高い状態を維持することが可能となり、グリスの劣化に起因 する不具合を未然に防ぐことができる。更に、グリスアップのメンテナンス作業 を省略することが可能となる。 According to the present invention described above, it is possible to maintain a state of low friction and high abrasion resistance for a long period of time without using a lubricant such as grease, and prevent problems caused by deterioration of grease. be able to. Further, it becomes possible to omit the maintenance work of grease up.
