のにおいて、変電機器回路の耐電圧試験等を行う場合に
、この避雷器を回路より切離するようにした避雷器の断
路用引上げ装置に関するものである。[Detailed Description of the Invention] The present invention is applicable to compact substation equipment in which a lightning arrester is housed in a tank filled with an insulating medium such as insulating oil or SF5 gas, and when carrying out withstand voltage tests of substation equipment circuits, etc. The present invention relates to a lifting device for disconnecting a lightning arrester, which disconnects the lightning arrester from a circuit.
近年変電設備の縮小化が進められ、遮断器、変圧器およ
び避雷器等を鉄槽に入れ油絶縁又はＳＦ５ガス等の高絶
縁レベルに保持し、これらを一体化して極めて縮小化し
た所謂縮小形変電設備が実用化されている。In recent years, substation equipment has been downsized, and circuit breakers, transformers, lightning arresters, etc. are placed in iron tanks and kept at a high insulation level such as oil insulation or SF5 gas, and these are integrated into a so-called downsized substation. The equipment has been put into practical use.
この様に避雷器が他の変電機器と一体化された変電設備
においては、変電機器回路の耐電圧を試験する場合には
避雷器を回路より切離して行う必要があり、その断路又
は接続は極めて狭い場所内で行う必要がある。In substation equipment where the lightning arrester is integrated with other substation equipment in this way, when testing the withstand voltage of the substation equipment circuit, it is necessary to disconnect the lightning arrester from the circuit and disconnect or connect it in an extremely narrow place. It needs to be done inside.
避雷器回路の断路方法として最も普通に考えられる方法
は電路と避雷器との間に専用の断路器を設ける方法であ
る。The most commonly considered method for disconnecting a lightning arrester circuit is to provide a dedicated disconnector between the electrical circuit and the lightning arrester.
しかし此の方法では断路器を設置するスペースを必要と
する為変電機器の縮小化にマイナス要因となる。However, this method requires space to install a disconnector, which is a negative factor in downsizing the substation equipment.
縮小化を図るには避雷器の接続部を断路器の接触子の形
状とし、直接避雷器本体を上下動させることにより避雷
器と電路と切離し又は接続を行なう方法が考えられてい
る。In order to reduce the size of the lightning arrester, a method has been considered in which the connection part of the lightning arrester is shaped like a contact of a disconnector, and the lightning arrester is disconnected from or connected to the electrical circuit by directly moving the surge arrester body up and down.

方法である。A contact 2 and a contact rod 9 on the electrical circuit side, which is provided opposite to the contact 2 on the storage tank 4 side and supported by an insulator 7.
In this method, the lightning arrester 1 is moved up and down as shown in FIG. 2 using a plurality of screws 12, and the lightning arrester 1 is connected or disconnected from the circuit.

The tank internal pressure is always sealed against the

し、このネジジヤツキ１２を回転させて避雷器１を上方
向に引上げる。When disconnecting lightning arrester 1 from the circuit from the state shown in Figure 1,
As shown in FIG. 2, remove the fixing bolts 6 of the lightning arrester 1, and use the tab holes 11 provided in the upper chamber of the lightning arrester 1 to set the number of sets of screws 12 (two shown in FIG. 2). This screw jack 12 is rotated to pull up the lightning arrester 1 upward.
避雷器１が引上げられると、該避雷器下端部の接触子２
ど電路の接触棒９との接触は外される。When the arrester 1 is pulled up, the contact 2 at the lower end of the arrester
The contact with the contact rod 9 of the electric circuit is removed.

。However, in such a pulling structure, the number of sets of screws is 1.
2 to move the arrester 1 up and down, if the screws 12 are not rotated uniformly in sequence, the arrester body may tilt while being pulled up. Therefore, when reconnecting after the test, the lower end contact of the arrester 2 and the contact rod 9 on the tank side must be very careful to align their centers.

ある。Also, if the sealing pressure of the insulating medium 3 sealed in the tank 4 housing the lightning arrester 1 is high, the sealing pressure must be lowered in advance and the fixing bolts 6 of the lightning arrester 1 must be removed. There is a risk that the internal pressure will rise abnormally and the insulating medium 3 such as SF5 gas or insulating oil in the pop-out tank may leak.
本考案は上述の問題点を解決するためになされたもので
ある。The present invention has been made to solve the above-mentioned problems.
即ち避雷器の中央部を一個のネジジヤツキで上下せしめ

３が漏れることがない等の優れた効果を発揮する。As described above, this invention uses a single screw 13 to create a lightning arrester 1.
Since the surge arrester 1 is configured to move up and down along its installation center, it moves up and down almost vertically when the arrester 1 moves up and down, and the arrester 1 does not tilt. Since there is no need to align the center positions of the lower end contactor 2 of the lightning arrester 1 and the contact rod 9, the work is extremely easy, and when the pressure of the insulating medium 3 in the storage tank 4 is high, it is possible to perform a lifting operation. bolt 15'
Even if the lightning arrester 1 is removed, the nut 19 is screwed into the screw jack 13 of the lifting fitting 14 provided on the lightning arrester 1, and the nut 1
Since the lightning arrester 9 is held down by the holding fitting 20, the lightning arrester does not rise abnormally due to internal pressure, and therefore exhibits excellent effects such as preventing the insulating medium 3 from leaking.
