Must. The mechanism of a pull-out relay is a plug-in type in which the relay body and case can be attached or detached at will, regardless of the charging state of the main circuit. As a function of this, when pulling out the main body, be sure to short-circuit the main circuit, especially the secondary circuit of the current transformer, and then install a mechanism that electrically disconnects the connection between the main circuit and the main body of the relay. Conversely, when inserting the relay body into the case and attempting to electrically connect the main circuit and the relay body, first make sure that the relay body and the main circuit are connected, and then connect the current transformer 2. It has the function of breaking the short circuit in the secondary circuit and allowing the secondary current of the current transformer to flow into the relay body. Moreover, as long as it has a pull-out mechanism, it must be usable not only for the secondary circuit of a current transformer but also for connecting the secondary circuit of an instrument transformer and a control circuit.

４２が接続される。 Conventionally, this type of plugging device (or connecting device) particularly used for the secondary circuit of a current transformer has a configuration as shown in FIG. A contactor 31 is provided,
This is protected by a protective insulating frame 36 and serves as an insertion-side terminal block 38 that is attached to the relay main body side, and a relay coil 42 is connected between both contacts 31, 31.

A secondary circuit of an alternator 41 is connected between both contacts 32, 32.

る。<Problems to be Solved by the Invention> The above describes the conventional plug device for current circuits (current transformer secondary circuits), but in FIG. If removed, it can be used as is for voltage circuits. In other words, the difference between the current circuit plug device and the voltage circuit plug device is that both shorting pieces 33 on the fixed side terminal block,
The structure is exactly the same except for the presence or absence of 33.

もある。 This can be seen in the relay coil 42 in FIG.
However, there is a risk that a current coil may be inserted into a fixed terminal block for a voltage circuit, and conversely, a relay 42 whose coil is a voltage coil may be inserted into a fixed terminal block for a current circuit (current transformer secondary circuit). There is also a risk that it may be inserted.

このような事態が発生したとき前者の場合過大
電流により継電器４２の電流コイルを焼損するこ

大となつて変流器４１を焼損するという問題があ
つた。 When such a situation occurs, in the former case, the current coil of the relay 42 will be burnt out due to excessive current, and in the latter case, the secondary load of the alternator will become excessive and the current transformer 41 will be burnt out. It was hot.

向の寸法が大きいという問題もあつた。 In addition, since both the insertion side terminal block 38 and the fixed side terminal block 39 have insulating walls 35, the depth of insertion when these are inserted is limited to the point where the insulating walls 35 come into contact with each other. There was also a problem that the size in the insertion/extraction direction during insertion was large.

The purpose is to

Provide a contact piece for short circuit.

る。<Function> The plugging device with the above configuration electrically connects one end of the contact piece of each insertion plug unit to the relay body, and connects one end of the receiving blade of each plug holder unit to the current transformer secondary circuit or instrument transformer. It is used by connecting to the secondary circuit of the device. When inserting an insertion plug into a plug holder in such a plugging device, for a current (current transformer secondary) circuit, the insertion piece of each insertion plug unit must first be inserted into the receiving blade of the corresponding plug holder unit. Then, the insulating plate attached to the insertion plug unit is inserted between both contact pieces of the plug receiving unit, the short circuit between both receiving blades is broken, and the secondary current of the current transformer flows into the relay body.

そして電圧回路用にあつては挿込栓ユニツトの
挿入片が対応する栓受ユニツトの受刃に確実に接
触する。 In the case of a voltage circuit, the insertion piece of the insertion plug unit reliably contacts the receiving blade of the corresponding plug holder unit.

無駄なスペースを生じない。 In addition, for current circuits, the tip of the insulating plate of the plug holder unit is almost up to the notch of the corresponding plug holder unit, and for voltage circuits, the tip of the insulating plate of the plug holder unit is up to the notch of the corresponding plug holder unit. Since the insertion can be made until the last minute, there is no wasted space when the insertion is completed.

み合わされて構成されることが多いので、実質的
にこのような不都合は生じないと思われる。 Furthermore, even if an attempt is made to insert the current circuit insertion plug unit into the voltage circuit plug holder unit, the insulating plate attached to the insertion plug unit and the insulating plate attached to the plug holder unit come into contact with each other, making it impossible to insert the unit. Conversely, it is possible to insert the voltage circuit insertion plug unit into the current circuit plug holder unit, but since the insulating plate is not attached to both, the contact piece of the plug holder unit will not open and the current transformer secondary circuit will not open. Since the short-circuit condition can be maintained, current transformer burnout accidents will not occur. Of course, a plug holder is rarely composed only of a plug holder unit for a current circuit, and is often constructed by appropriately combining a plug holder unit for a voltage circuit and a plug holder for a current circuit, so this kind of inconvenience does not occur in practice. I think that the.

The connection with is disconnected. Therefore, after the relay main body is pulled out, the current transformer secondary current circulates through the terminal-cum-receiving blades 23, 23.
