It depends on the program. Furthermore, when measuring the response voltage of a relay, the permissible deviation of the return spring must be Since the values associated with the differences are also added to this, in the completed relay, the various values of the relay Checking whether different data are within acceptable deviation ranges is relatively time-consuming. The second thing in particular is the burnout margin at the relay contacts. This also applies to measurements. This relay contact is a so-called micro relay. can no longer be measured non-destructively due to their limited properties and therefore It can only be measured through random inspections.

図1では電磁形継11E器のインダクタンスに対する測定回路の直流電圧源が符 号10で示されている。スイッチ11を介してコンデンサ12が直流電圧[10 に並列に接続されている。コンデンサ12に並列して、別のスイ、ノチ13を介 して電磁形継電器15の励磁コイル14が設けられている。この電磁形継電器1 5のコイル鉄心16は接極子17と共働する。この接極子17は、戻しばね18 によってその静止位置に維持される。接極子17に固定されている接点ばね19 は前方で継電器接点20を支持する。この継電器接点20は定置の接極子接点2 1と共働する。n定装置123の感知部22によって接極子17は、コイル鉄心 16に押しつけられるか又は連続的にコイル鉄心16から戻しばね18を用いて 引きはずされる。この場合測定装置23の測定回路24は、継電器接点の開閉を 検出するために継電器接点20.21に接続される。測定装置23の別の測定回 路25は、励磁コイル14に並列に接続される。スイッチ11及び13は、電気 的かつ機械的に次のように相互でインターロックされる。すなわち該スイッチ1 1及び13が図中破線で示されているように交互にのみ開かれたり閉じられたり するようにインターロック(連動)される。In Figure 1, the DC voltage source of the measurement circuit for the inductance of the electromagnetic coupling 11E is in agreement. It is indicated by No. 10. The capacitor 12 is connected to the DC voltage [10 are connected in parallel. In parallel with the capacitor 12, another switch is connected through the notch 13. An excitation coil 14 of an electromagnetic relay 15 is provided. This electromagnetic relay 1 The coil core 16 of No. 5 cooperates with the armature 17. This armature 17 has a return spring 18 is maintained in its rest position by. Contact spring 19 fixed to armature 17 supports the relay contacts 20 at the front. This relay contact 20 is a fixed armature contact 2 Work together with 1. The armature 17 is detected by the sensing unit 22 of the n-determining device 123 as the coil core 16 or continuously from the coil core 16 using a spring 18 It gets pulled off. In this case, the measuring circuit 24 of the measuring device 23 controls the opening and closing of the relay contacts. Connected to relay contacts 20.21 for detection. Another measurement run of the measuring device 23 The line 25 is connected in parallel to the excitation coil 14 . Switches 11 and 13 are electrical physically and mechanically interlocked with each other as follows: That is, the switch 1 1 and 13 are only opened and closed alternately as shown by the broken lines in the figure. are interlocked (interlocked) so that
次に図2、図3に基づき図1による測定及び検査回路の作用を説明する。Next, the operation of the measurement and inspection circuit according to FIG. 1 will be explained based on FIGS. 2 and 3.
スイッチ11が閉じられるとコンデンサ12は直流電圧1110によって充電さ れる。′lIA定装置23の感知部22により接極子17はコイル鉄心16に押 しつけられる。この場合継電器接点20.21は閉じられる。When switch 11 is closed, capacitor 12 is charged by DC voltage 1110. It will be done. The armature 17 is pressed against the coil core 16 by the sensing part 22 of the IA constant device 23. Disciplined. In this case relay contacts 20.21 are closed.
この状態でスイッチ11及び13は切換られる。それによりコンデンサ12は継 電器15の励磁コイル14を介して放電される。図2にはその際の励磁コイル1 4に生じた電圧経過が示されている。この場合コンデンサ12と励磁コイル14 は振動回路を形成する。この振動回路はオーム抵抗によって減衰され、急激に弱 まっていく。測定装置23では測定電流回路25を介して励磁コイル14におけ る最初の完全な電圧振動が検出され、以下の2つの式、すなわち に従って、継電器15の励磁系に対する最初のインダクタンスfiM1がめられ る。このインダクタンス値Mlは図3に示されている。Lmin及びLmaxか らなる許容限界値は、測定装置123のメモリ23a内の特性曲線と(。7てテ ーブルの形で含まれている。前記許容限界値は接極子10が当接した場合の距離 S=0毎にメモリ23aから取り出され、測定装置23の検査回路23b内で、 当該検出されたインダクタンス値Mlと比較される9図3に示されているように 請求められた継電器15のインダクタンス#IM1は、2つの所定の値M m a xとMminとの間にある。従って継電器15の応動電圧及び復帰電圧に関 して磁気的許容偏差範囲内にある。In this state, switches 11 and 13 are switched. This causes the capacitor 12 to It is discharged through the excitation coil 14 of the electric appliance 15. Figure 2 shows the excitation coil 1 at that time. 4 is shown. In this case, the capacitor 12 and the excitation coil 14 forms an oscillating circuit. This oscillating circuit is damped by an ohmic resistor and suddenly weakens. I'm waiting. In the measuring device 23, a current is generated in the exciting coil 14 via the measuring current circuit 25. The first complete voltage oscillation is detected and the following two equations, i.e. Accordingly, the initial inductance fiM1 for the excitation system of the relay 15 is determined. Ru. This inductance value Ml is shown in FIG. Lmin and Lmax? The permissible limit values are based on the characteristic curve in the memory 23a of the measuring device 123 and (. included in the form of a cable. The allowable limit value is the distance when the armature 10 contacts It is taken out from the memory 23a every time S=0, and in the test circuit 23b of the measuring device 23, 9 is compared with the detected inductance value Ml, as shown in Figure 3. The requested inductance #IM1 of the relay 15 has two predetermined values M m It is between a x and Mmin. Therefore, regarding the response voltage and release voltage of the relay 15, and is within the magnetic tolerance range.
さらに図3からは次のようなことがわかる。すなわち継電器のインダクタンスL が、距離Sに依存して実質的にat器の作用エアギヤツブに依存する特性曲線に 従って降下していることがわかる。前記路1IISは、接極子17の引きはずし により当該継電器接点20が定置接点21から離れていく距離のことである。2 つの限界値−特性曲線Lmax及びLminの他にもメモリ23aには多数の別 の特性曲線がファイルされている。これらの特性曲線は、特性曲線LmaxとL minとの間に均一に分布している。それにより請求められたインダクタンス値 Mlは、開かれた接極子17の移動距離に依存した当該特性曲線Kに割り当てら れる。Furthermore, the following can be seen from FIG. In other words, the inductance L of the relay However, depending on the distance S, the characteristic curve substantially depends on the working air gear of the AT device. Therefore, it can be seen that it is descending. Said path 1IIS is the tripping of the armature 17. This is the distance that the relay contact 20 is away from the stationary contact 21. 2 In addition to the two limit value-characteristic curves Lmax and Lmin, the memory 23a also contains a number of Characteristic curves are filed. These characteristic curves are the characteristic curves Lmax and L It is uniformly distributed between min. The resulting inductance value Ml is assigned to the characteristic curve K in question depending on the travel distance of the opened armature 17. It will be done.
非破壊的に、図1による回路を用いて継電器15の焼損に対する余裕度をめるこ とも可能である。この目的のためにスイッチ11と13は新たに切換られ、コン デンサ12が新たに直流電圧源IOによって充電される。その後継電器接点20 .21を有している測定電流回路24を介して測定電流が印加され、感知部22 が当該接点20.21が開かれるまでキャンセルされる。継電器15のこの状態 において、スイッチ11と13の新たな切換によりコンデンサ12が励磁コイル 14を介して新たに放電され、同じように測定装置23により第2のインダクタ ンス値M2が測定装置23においてめられる。この測定値は特性曲線に上にある ので、図3のようにメモリ23aにファイルされたテーブルから距離S2が、焼 損に対する余裕度として得られる。この値S2は、メモリ23aにファイルされ た上側及び下側の限界値Smax、Sm1nとの比較によって定められる。焼損 に対する余裕度としてめられた値S2が2つの限界値の間にあると、測定装置2 3は良好−表示信号を出力する。前記値s2が2つの限界値の外側にあると、測 定装置23は不良FIG 1Non-destructively, the circuit shown in FIG. 1 can be used to increase the margin for burnout of the relay 15. Both are possible. For this purpose, switches 11 and 13 are newly switched and the Capacitor 12 is newly charged by DC voltage source IO. Its successor electrical contact 20 .. A measuring current is applied via a measuring current circuit 24 having a sensor 22 . is canceled until the corresponding contact 20.21 is opened. This state of relay 15 , new switching of switches 11 and 13 causes capacitor 12 to switch to the excitation coil. 14 and is similarly discharged by the measuring device 23 into the second inductor. A value M2 is measured in the measuring device 23. This measurement is above the characteristic curve Therefore, the distance S2 from the table filed in the memory 23a as shown in FIG. It is obtained as a margin against losses. This value S2 is filed in the memory 23a. It is determined by comparison with the upper and lower limit values Smax and Sm1n. Burnt out If the value S2 determined as the margin for is between the two limit values, the measuring device 2 3 is good - outputs a display signal. If the value s2 is outside the two limits, the measurement The fixed device 23 is defective FIG. 1
