本發明係關於遮斷器之滑觸量測定方法及其滑觸量測定裝置,尤其,關於即使在無法以構造直接測定遮斷器之滑觸量的情況下亦合適的遮斷器之滑觸量測定方法及其滑觸量測定裝置。 The present invention relates to a method for measuring a sliding contact amount of a circuit breaker and a sliding contact amount measuring device thereof, and more particularly to a sliding contact of a suitable interrupter even in the case where the sliding amount of the interrupter cannot be directly measured by the structure. Measuring method and measuring device for sliding amount.
已知利用電磁操作裝置之電磁力而將真空遮斷器等之遮斷器作開閉的電磁操作式開閉裝置。於此電磁操作式開閉裝置,係採用將供以驅動電磁鐵用的能量蓄積於電容器,根據蓄積於電容器之能量予以產生電磁力,將此電磁力帶來的驅動力透過鏈接機構而傳達,使真空遮斷器接通動作之構成。 An electromagnetic operation type opening and closing device that opens and closes a breaker such as a vacuum interrupter by an electromagnetic force of an electromagnetic operating device is known. In the electromagnetic operation type opening and closing device, the energy for driving the electromagnet is accumulated in the capacitor, and the electromagnetic force is generated based on the energy stored in the capacitor, and the driving force generated by the electromagnetic force is transmitted through the link mechanism. The composition of the vacuum interrupter is turned on.
此外,採用於接通時將遮斷彈簧作壓縮而於遮斷彈簧蓄積能量,於開放時,係於電磁鐵之線圈,使與接通時係逆向的電流流過而從電磁鐵予以產生逆向之電磁力,將此電磁力與蓄積於遮斷彈簧之彈簧力,作為與接通時係逆向的驅動力賦予鏈接機構而就真空遮斷器作開閉操作之構成。 Further, when the switch is turned on, the blocking spring is compressed to accumulate energy in the blocking spring, and when it is opened, it is connected to the coil of the electromagnet, so that a reverse current flows when it is turned on, and a reverse direction is generated from the electromagnet. In the electromagnetic force, the electromagnetic force and the spring force accumulated in the blocking spring are configured to open and close the vacuum interrupter by providing a link mechanism to the link mechanism when the driving force is reversed.
另外,真空遮斷器,係持續20年以上於苛刻之環境作使用者,故因長期間之使用而重複真空遮斷器之開閉時,對於可動接點賦予接觸壓力的滑觸彈簧之滑觸量會減少。於此滑觸量脫離既定之滑觸量的情況下,係變得無法於接點間賦予既定之接觸壓力,接觸電阻增加,通電導致的發熱增加而會產生引起故障之可能性。要防範故障於未然,係需要定期測定滑觸量,作調整。 In addition, the vacuum interrupter is used for a user who has been in a harsh environment for more than 20 years. Therefore, when the vacuum interrupter is opened and closed for a long period of time, the sliding contact of the sliding contact spring is applied to the movable contact. The amount will decrease. When the amount of slippage is out of a predetermined amount of slip, it is impossible to provide a predetermined contact pressure between the contacts, the contact resistance is increased, and the heat generation due to energization is increased to cause a possibility of malfunction. To prevent failures before they occur, it is necessary to periodically measure the amount of sliding and make adjustments.
在就如此之真空遮斷器的滑觸量作測定之現有技術方面,有記載於專利文獻1者。於此專利文獻1,係記載設置阻力值響應於真空遮斷器之驅動軸的旋轉而變化之滑動變阻器,將該輸出變化與從遮斷器接點之非導通至導通的變化一起顯示於示波器,從而測定滑觸量。 The prior art for measuring the amount of sliding contact of such a vacuum interrupter is described in Patent Document 1. Patent Document 1 describes a sliding rheostat in which a resistance value is changed in response to rotation of a drive shaft of a vacuum interrupter, and the output change is displayed on the oscilloscope together with a change from non-conducting to conduction of the contact of the interrupter. To determine the amount of slip.

The open position moves to the manual position of the contact position.

接著,就上述之構成下的滑觸彈簧34之滑觸量的測定方法作說明。 Next, a method of measuring the sliding amount of the sliding spring 34 in the above configuration will be described.
首先,使真空遮斷器100為遮斷狀態,調整成螺栓51與可動桿9的上部可動桿9C接觸。接著,接通直流電源裝置38之電源,轉動螺栓51而按壓可動桿9,使得其驅動力透過鏈接機構12、及絕緣桿11而傳達至遮斷部13,變移成可動接點7與固定接點8接觸之接觸狀態。可動接點7與固定接點8接觸而成為導通狀態,蜂鳴檢驗器37鳴響時,停止轉動螺栓51。此時,內建於安裝了蜂鳴檢驗器37之遮斷部13的真空閥14係成為觸點(基準位置)。 First, the vacuum interrupter 100 is placed in an interrupted state, and the bolt 51 is adjusted to come into contact with the upper movable rod 9C of the movable lever 9. Next, the power of the DC power supply unit 38 is turned on, and the bolt 51 is rotated to press the movable lever 9 so that the driving force is transmitted to the blocking portion 13 through the link mechanism 12 and the insulating rod 11, and is shifted into the movable contact 7 and fixed. Contact state of contact 8 contact. The movable contact 7 comes into contact with the fixed contact 8 to be in an on state, and when the buzzer 37 sounds, the rotation of the bolt 51 is stopped. At this time, the vacuum valve 14 built in the blocking portion 13 to which the buzzer 37 is attached is a contact (reference position).
在此狀態下就移動推車33之底面部至絕緣桿11的距離,利用深度計等而作測定,使此為基準值D1。就其他相亦進行同樣的操作,就觸點之距離D1作測定。再者,轉動螺栓51時,永久磁鐵16的吸引力超過滑觸彈簧34與遮斷彈簧25之力,電磁操作裝置6係自動成為接通狀態。在此狀態下,再度就移動推車33之底面部至絕 緣桿11的距離,利用深度計等而作測定,使此為行程長度D2。 In this state, the distance from the bottom surface portion of the cart 33 to the insulating rod 11 is measured by a depth gauge or the like, and this is referred to as a reference value D1. The same operation was performed for the other phases, and the distance D1 of the contact was measured. Further, when the bolt 51 is rotated, the attraction force of the permanent magnet 16 exceeds the force of the sliding spring 34 and the blocking spring 25, and the electromagnetic operating device 6 is automatically turned on. In this state, the bottom of the cart 33 is again moved to the absolute The distance of the edge rod 11 is measured by a depth gauge or the like, and this is the stroke length D2.
就藉上述尺寸測定動作而得之各相下的距離之差分=D2-D1作計算,使得可算出滑觸量(尺寸)。 The difference (D2-D1) of the distances in the respective phases obtained by the above-described dimensional measurement operation is calculated so that the sliding amount (size) can be calculated.
亦即,在本實施例,係於使遮斷部13為遮斷狀態後,藉螺栓51就電磁操作裝置6的可動桿9作操作,將藉此螺栓51而操作之電磁操作裝置6的驅動力透過鏈接機構12及絕緣桿11而傳達至滑觸彈簧34,從而使可動接點7從斷開位置移動至接觸位置而接觸於固定接點8而作成導通狀態,使成為此導通狀態之時點的移動推車33之底面與絕緣桿11之距離為基準值D1,同時使從該狀態就螺栓51作操作而使滑觸彈簧34位移使得此滑觸彈簧34收縮時的移動推車33之底面與絕緣桿11之距離為行程長度D2,以此D2-D1為滑觸彈簧之滑觸量而作測定。 That is, in the present embodiment, after the blocking portion 13 is in the blocking state, the movable lever 9 of the electromagnetic operating device 6 is operated by the bolt 51, and the electromagnetic operating device 6 operated by the bolt 51 is driven. The force is transmitted to the sliding spring 34 through the link mechanism 12 and the insulating rod 11, and the movable contact 7 is moved from the off position to the contact position to contact the fixed contact 8 to be in an on state, so that the conduction state is reached. The distance between the bottom surface of the moving cart 33 and the insulating rod 11 is the reference value D1, and the bottom surface of the moving cart 33 when the sliding spring 34 is displaced by the operation of the bolt 51 from the state. The distance from the insulating rod 11 is the stroke length D2, and D2-D1 is measured as the sliding amount of the sliding spring.
作成如此之本實施例,使得即使在無法從具有滑觸彈簧34之機構部而直接測定滑觸彈簧34之滑觸量的情況下,仍可從替代部之測定與位移的差分算出滑觸量。 In the present embodiment, even when the sliding amount of the sliding spring 34 cannot be directly measured from the mechanism portion having the sliding spring 34, the sliding amount can be calculated from the difference between the measurement and the displacement of the replacement portion. .
如以上,依本實施例,即獲得即使為無法直接測定滑觸量之構造,仍可在不使用大規模、且特別之測定器具下測定滑觸量的效果。 As described above, according to the present embodiment, even in a structure in which the amount of sliding contact cannot be directly measured, the effect of measuring the amount of sliding can be measured without using a large-scale and special measuring instrument.
於圖3,就供以說明本發明的遮斷器之滑觸量測定方法的實施例2用之電磁操作裝置6的一部分作繪示。 In Fig. 3, a part of the electromagnetic operating device 6 for the second embodiment of the method for measuring the slip amount of the interrupter of the present invention is shown.
本實施例,係如前述之實施例1,無法就在遮斷部13之下方的絕緣桿11之位移量作測定的情況下之替代方案。為此,構成係與前述之實施例1相同,故此處之說明係省略。 This embodiment is an alternative to the case where the displacement amount of the insulating rod 11 below the blocking portion 13 cannot be measured as in the first embodiment described above. For this reason, the configuration is the same as that of the first embodiment described above, and therefore the description herein is omitted.
在示於圖3之本實施例,係於使在就電磁操作裝置6的可動桿9作操作之螺栓51與可動桿9之上部可動桿9C接觸的狀態下之螺栓51的上部前端至框體前方頂板部4a的距離為L1,使轉動螺栓51使得該螺栓51之頭部下降至框體前方頂板部4a時的螺栓51之上部前端至框體前方頂板部4a的距離為L2,且鏈接機構12之驅動桿比為a時,以a(L1-L2)為滑觸彈簧之滑觸量而作測定。 In the embodiment shown in Fig. 3, the upper end of the bolt 51 is brought to the frame in a state where the bolt 51 for operating the movable lever 9 of the electromagnetic operating device 6 is in contact with the upper movable rod 9C of the movable lever 9. The distance from the front top plate portion 4a is L1, and the distance from the front end of the upper portion of the bolt 51 to the front portion 4a of the frame when the head of the bolt 51 is lowered to the front plate portion 4a of the frame body is L2, and the link mechanism is provided. When the drive rod ratio of 12 is a, a (L1-L2) is used as the sliding contact amount of the sliding spring.
藉此,進一步,可在不將作為滑觸測定對象之真空遮斷器100解體(卸除正面蓋等),不使用特別之測定架台下,就滑觸量的測定從真空遮斷器100之本體上部作測定,尤其可大幅縮短維護時之滑觸測定時間。 In this way, the vacuum interrupter 100 that is the target of the sliding measurement is not disassembled (the front cover or the like is removed), and the amount of the sliding contact is measured from the vacuum interrupter 100 without using a special measuring stand. The upper part of the body is measured, and in particular, the slip measurement time during maintenance can be greatly shortened.
即使為如此之本實施例,其效果,係仍如同實施例1。 Even in the case of this embodiment, the effect is the same as in the first embodiment.
另外,本發明係非限定於上述之實施例者,含各式各樣的變化例。例如,上述之實施例係為了以容易理解的方式說明本發明而詳細說明者,未必限定於具備所 說明之全部的構成者。就實施例的構成之一部分,可作構成之追加、刪除、置換。 Further, the present invention is not limited to the above-described embodiments, and includes various modifications.
