【発明の属する技術分野】
本発明は、電源制御回路に関し、さらに詳しくは、障害が解消されないうちに異常検出スイッチがオンに戻ってしまっても負荷へ電力が自動的に再供給されないようにした電源制御回路に関する。
【０００２】
【従来の技術】
図８に、正常状態を検出してオンになり異常状態を検出してオフになる異常検出スイッチを利用した従来の電源制御回路の一例を示す。
この電源制御回路５００は、温度，圧力，電圧，電流などの物理量が正常状態にあることを検出してオンになると共に異常状態にあることを検出してオフになる異常検出スイッチＴｈと、通電時に第１オン接点Ｘｂをオンにすると共に非通電時に第１オン接点Ｘｂをオフにする第１リレー手段Ｘとを具備してなり、前記異常検出スイッチＴｈと前記第１リレー手段Ｘが直列回路を構成しており、該直列回路が電源に接続され、前記第１オン接点Ｘｂを介して負荷に電力を供給する構成になっている。
【０００３】
図９に示すように、正常状態を検出して異常検出スイッチＴｈがオンになっているときに操作者が電源スイッチｐｗをオンにすると、異常検出スイッチＴｈを介して第１リレー手段Ｘが通電されるため、第１オン接点Ｘｂがオンになり、負荷に電力が供給される。
【０００４】
図１０に示すように、異常状態を検出して異常検出スイッチＴｈがオフになると、第１リレー手段Ｘが通電されなくなるため、第１オン接点Ｘｂがオフになり、負荷に電力が供給されなくなる。
【０００５】
【発明が解決しようとする課題】
上記従来の電源制御回路５００では、例えば、負荷温度が限界値より低温である状態を正常状態として異常検出スイッチＴｈで検出し、負荷温度が限界値より高温である状態を正常状態として異常検出スイッチＴｈで検出するようにしておくと、何らかの障害により負荷温度が限界値を越えると、負荷への電力供給が断たれるため、負荷を保護できることになる。なお、このような異常検出スイッチＴｈの例としては、サーミスタ・スイッチが挙げられる。
【０００６】
しかし、負荷への電力供給が断たれて負荷温度が下がり、障害が解消されないうちに異常検出スイッチＴｈがオンに戻ってしまうと、負荷へ電力が自動的に再供給されてしまう問題点がある。
そこで、本発明の目的は、障害が解消されないうちに異常検出スイッチがオンに戻ってしまっても負荷へ電力が自動的に再供給されないようにした電源制御回路を提供することにある。
【０００７】
【課題を解決するための手段】
第１の観点では、本発明は、正常状態の検出によりオンになり異常状態の検出によりオフになる異常検出スイッチ手段Ｔｈと、通電時に第１オフ接点Ｘａをオフにすると共に非通電時に第１オフ接点Ｘａをオンにする第１リレー手段Ｘと、通電時に一定時間遅れて第２オフ接点Y1ａおよび第３オフ接点Y2ａをオフにすると共に非通電時に第２オフ接点Y1ａおよび第３オフ接点Y2ａをオンにする第２リレー手段odＹとを具備し、前記第２オフ接点Y1ａと前記異常検出スイッチＴｈと前記第１リレー手段Ｘが第１直列回路を構成しており、前記第１直列回路が電源に接続され、前記第２リレー手段odＹと前記第１オフ接点Ｘａが第２直列回路を構成しており、前記第２直列回路が電源に接続され、前記第３オフ接点Y2ａを介して負荷に電力を供給することを特徴とする電源制御回路１００を提供する。
【０００８】
上記第１の観点による電源制御回路では、正常状態で電源スイッチをオンにすると、第２オフ接点Y1ａおよび異常検出スイッチＴｈを介して第１リレー手段Ｘが通電されるため第１オフ接点Ｘａがオフになり、第２リレー手段odＹは非通電となり、第３オフ接点Y2ａを介して負荷に電力が供給される。電源スイッチをオンにした瞬間は第２リレー手段odＹにも通電されるが、第２オフ接点Y1ａがオフになるのに一定時間（例えば１秒間）遅れるため、第２オフ接点Y1ａがオフになる前に第１オフ接点Ｘａがオフになり、結果的に第２リレー手段odＹは非通電のままとなる。
【０００９】
異常状態を検出して異常検出スイッチＴｈがオフになると、第１リレー手段Ｘが通電されなくなるため、第１オフ接点Ｘａがオンになり、第１オフ接点Ｘａを介して第２リレー手段odＹが通電されるため、第３オフ接点Y2ａがオフになり、負荷に電力が供給されなくなる。
【００１０】
障害が解消されないうちに異常検出スイッチＴｈがオンに戻ってしまっても、第２オフ接点Y1ａがオフであるため、第１リレー手段Ｘが非通電のままとなり、第１オフ接点Ｘａがオンのままとなり、第２リレー手段odＹが通電され続けるため、第３オフ接点Y2ａがオフのままとなり、負荷に電力が自動的に再供給されることはない。
【００１１】
操作者が電源スイッチを一旦オフにし、異常検出スイッチＴｈがオンに戻り且つ障害を解消した後、操作者が電源スイッチをオンにすると、負荷へ電力を再供給できる。
【００１２】
【発明の実施の形態】
以下、図に示す実施の形態により本発明を詳細に説明する。なお、これにより本発明が限定されるものではない。
【００１３】
図１は、本発明の一実施形態に係る電源制御回路１００を示す構成図である。
この電源制御回路１００は、正常状態の検出によりオンになり異常状態の検出によりオフになる異常検出スイッチＴｈと、通電時に第１オフ接点Ｘａをオフにすると共に非通電時に第１オフ接点Ｘａをオンにする第１リレーＸと、通電時に１秒間遅れて第２オフ接点Y1ａおよび第３オフ接点Y2ａをオフにすると共に非通電時に第２オフ接点Y1ａおよび第３オフ接点Y2ａをオンにする第２リレーodＹとを具備している。
前記第２オフ接点Y1ａと異常検出スイッチＴｈと第１リレーＸが第１直列回路を構成しており、該第１直列回路は電源に接続されている。
前記第２リレー手段odＹと第１オフ接点Ｘａが第２直列回路を構成しており、該第２直列回路は電源に接続されている。
前記第３オフ接点Y2ａを介して、負荷に電力が供給される。
【００１４】
また、電源制御回路１００は、前記第１リレーＸにより通電時にオンにされると共に非通電時にオフにされる第１オン接点Ｘｂを具備している。
前記第１オン接点Ｘｂは、前記第２オフ接点Y1ａと並列に接続されている。
【００１５】
さらに、電源制御回路１００は、前記第２リレーodＹにより通電時に１秒間遅れてオンにされると共に非通電時にオフにされる第２オン接点Y1ｂと、異常時表示灯Ｌとを具備している。
前記第２オン接点Y1ｂと前記異常時表示灯Ｌとは第３直列回路を構成しており、該第３直列回路は電源に接続されている。
【００１６】
図２に示すように、正常状態を検出して異常検出スイッチＴｈがオンになっているときに操作者が電源スイッチｐｗをオンにすると、第２オフ接点Y1ａおよび異常検出スイッチＴｈを介して第１リレー手段Ｘが通電されるため、第１オフ接点Ｘａがオフになり、第２リレー手段odＹは非通電のままとなり、第３オフ接点Y2ａを介して負荷に電力が供給される。
なお、電源スイッチｐｗをオンにした瞬間は第２リレー手段odＹに通電されるが、第２オフ接点Y1ａがオフになるのに１秒間遅れるため、第２オフ接点Y1ａがオフになる前に第１オフ接点Ｘａがオフになり、結果的に第２リレー手段odＹは非通電のままとなる。
第１オン接点Ｘｂを第２オフ接点Y1ａと並列に接続しているのは、接点のチャタリングによる誤動作を避けるためである。
【００１７】
図３に示すように、異常状態を検出して異常検出スイッチＴｈがオフになると、第１リレー手段Ｘが通電されなくなるため、第１オフ接点Ｘａがオンに戻り、第２リレー手段odＹに通電される。すると、１秒後に、図４に示すように、第３オフ接点Y2ａがオフになり、負荷に電力が供給されなくなる。同時に、第２オフ接点Y2ａがオフになる。また、第２オン接点Y1ｂがオンになり、異常時表示灯Ｌが通電されて点灯する。
【００１８】
図５に示すように、障害が解消されないうちに異常検出スイッチＴｈがオンに戻ってしまっても、第１オン接点Ｘｂおよび第２オフ接点Y1ａがオフであるため、第１リレー手段Ｘが非通電のままとなり、第１オフ接点Ｘａがオンのままとなり、第２リレー手段odＹが通電され続けるため、第３オフ接点Y2ａがオフのままとなり、負荷に電力が自動的に再供給されることはない。
【００１９】
図６に示すように、操作者が電源スイッチｐｗを一旦オフにすると、第２リレー手段odＹが非通電になるため、第２オフ接点Y1ａおよび第３オフ接点Y2ａがオンに戻る。この状態から異常検出スイッチＴｈがオンに戻ると、図１の初期状態になる。そこで、障害を解消した後、操作者が電源スイッチｐｗをオンにすると、図２を参照して説明したように負荷へ電力を再供給できる。
【００２０】
図７は、図２の状態（負荷へ電力を供給している状態）で停電になった状態を示している。
第１リレー手段Ｘが非通電になるため、第１オフ接点Ｘａがオンに戻る。この状態で停電から復旧すると、図２の状態に自動的に戻り、負荷へ電力を自動的に再供給できる。
【００２１】
例えば、負荷が、ＭＲＩ（Magnetic Resonanse Imaging）装置のマグネットコイル（静磁場コイル）とする。また、異常検出スイッチＴｈが、マグネット温度が限界値より低温である状態を検出してオンとなり、マグネット温度が限界値より高温である状態を検出してオフになるサーミスタ・スイッチとする。
すると、何らかの障害によりマグネット温度が限界値を越えると、マグネットコイルへの電力供給が断たれるため、マグネットコイルを保護できる。
【００２２】
【発明の効果】
本発明の電源制御回路によれば、何らかの障害に起因する異常を検出した時に負荷への電力供給を停止し負荷を保護することが出来る。また、障害が解消されないうちに異常が検出されなくなっても負荷へ電力が自動的に再供給されることを防止できる。

BACKGROUND OF THE INVENTION
The present invention relates to a power supply control circuit, and more particularly to a power supply control circuit that prevents power from being automatically resupplied to a load even if an abnormality detection switch is turned on before the failure is resolved.
[0002]
[Prior art]
FIG. 8 shows an example of a conventional power supply control circuit using an abnormality detection switch that detects a normal state and turns on and detects an abnormal state and turns off.
The power supply control circuit 500 detects that physical quantities such as temperature, pressure, voltage, and current are in a normal state and is turned on, and detects an abnormal state and turns off, and an energization switch Th And a first relay means X for turning on the first on contact Xb and turning off the first on contact Xb when not energized. The abnormality detection switch Th and the first relay means X are connected in series. The series circuit is connected to a power source and supplies power to the load via the first ON contact Xb.
[0003]
As shown in FIG. 9, when the operator turns on the power switch pw when the normal state is detected and the abnormality detection switch Th is turned on, the first relay means X is energized via the abnormality detection switch Th. Therefore, the first on contact Xb is turned on, and power is supplied to the load.
[0004]
As shown in FIG. 10, when an abnormal state is detected and the abnormality detection switch Th is turned off, the first relay means X is not energized, so the first on contact Xb is turned off and power is not supplied to the load. .
[0005]
[Problems to be solved by the invention]
In the conventional power supply control circuit 500, for example, a state where the load temperature is lower than the limit value is detected by the abnormality detection switch Th as a normal state, and a state where the load temperature is higher than the limit value is detected as a normal state. If the detection is made by Th, if the load temperature exceeds a limit value due to some trouble, the power supply to the load is cut off, so that the load can be protected. An example of such an abnormality detection switch Th is a thermistor switch.
[0006]
However, if the power supply to the load is cut off, the load temperature falls, and the failure detection switch Th is turned on before the failure is resolved, there is a problem that the power is automatically resupplied to the load. .
SUMMARY OF THE INVENTION An object of the present invention is to provide a power supply control circuit in which power is not automatically resupplied to a load even if an abnormality detection switch is turned on before the failure is resolved.
[0007]
[Means for Solving the Problems]
In a first aspect, the present invention provides an abnormality detection switch means Th that is turned on when a normal state is detected and turned off when an abnormal state is detected. The first relay means X for turning on the off contact Xa, and the second off contact Y1a and the third off contact Y2a when turning off the second off contact Y1a and the third off contact Y2a with a certain time delay when energized. Second relay means odY for turning on, the second off contact Y1a, the abnormality detection switch Th, and the first relay means X constitute a first series circuit, and the first series circuit is Connected to a power source, the second relay means odY and the first off contact Xa constitute a second series circuit, the second series circuit is connected to the power source, and a load is passed through the third off contact Y2a. Supply power to A power
[0008]
In the power supply control circuit according to the first aspect, when the power switch is turned on in the normal state, the first relay means X is energized via the second off contact Y1a and the abnormality detection switch Th. The second relay means odY is de-energized and power is supplied to the load via the third off contact Y2a. Although the second relay means odY is energized at the moment when the power switch is turned on, the second off contact Y1a is turned off because the second off contact Y1a is delayed for a certain time (for example, 1 second). Before, the first off contact Xa is turned off, and as a result, the second relay means odY remains in a non-energized state.
[0009]
When the abnormal state is detected and the abnormality detection switch Th is turned off, the first relay means X is not energized, so the first off contact Xa is turned on, and the second relay means odY is turned on via the first off contact Xa. Since it is energized, the third off contact Y2a is turned off, and power is not supplied to the load.
[0010]
Even if the abnormality detection switch Th returns to ON before the failure is resolved, the second relay contact Y1a is OFF, so the first relay means X remains deenergized and the first OFF contact Xa is ON. Since the second relay means odY continues to be energized, the third off contact Y2a remains off, and power is not automatically resupplied to the load.
[0011]
After the operator turns off the power switch once, the abnormality detection switch Th returns to the on state and the failure is resolved, when the operator turns on the power switch, the power can be supplied again to the load.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings. Note that the present invention is not limited thereby.
[0013]
FIG. 1 is a configuration diagram showing a power
The power
The second off contact Y1a, the abnormality detection switch Th, and the first relay X constitute a first series circuit, and the first series circuit is connected to a power source.
The second relay means odY and the first off contact Xa constitute a second series circuit, and the second series circuit is connected to a power source.
Electric power is supplied to the load through the third off contact Y2a.
[0014]
The power
The first on contact Xb is connected in parallel with the second off contact Y1a.
[0015]
Further, the power
The second on-contact Y1b and the abnormal indicator lamp L constitute a third series circuit, and the third series circuit is connected to a power source.
[0016]
As shown in FIG. 2, when the operator turns on the power switch pw when the normal state is detected and the abnormality detection switch Th is turned on, the second turn-off contact Y1a and the abnormality detection switch Th are used. Since the first relay means X is energized, the first off contact Xa is turned off, the second relay means odY remains unenergized, and power is supplied to the load via the third off contact Y2a.
The second relay means odY is energized at the moment when the power switch pw is turned on. However, since the second off contact Y1a is turned off for one second, the second relay means odY is turned on before the second off contact Y1a is turned off. The 1-off contact Xa is turned off, and as a result, the second relay means odY remains unenergized.
The reason why the first ON contact Xb is connected in parallel with the second OFF contact Y1a is to avoid malfunction due to chattering of the contact.
[0017]
As shown in FIG. 3, when the abnormal state is detected and the abnormality detection switch Th is turned off, the first relay means X is not energized, so the first off contact Xa is turned back on and the second relay means odY is energized. Is done. Then, after one second, as shown in FIG. 4, the third off contact Y2a is turned off, and power is not supplied to the load. At the same time, the second off contact Y2a is turned off. In addition, the second on contact Y1b is turned on, and the abnormal time indicator lamp L is energized and lights up.
[0018]
As shown in FIG. 5, even if the abnormality detection switch Th returns to ON before the failure is resolved, the first relay means X is not turned on because the first ON contact Xb and the second OFF contact Y1a are OFF. Since the first off contact Xa remains on and the second relay means odY continues to be energized, the third off contact Y2a remains off and power is automatically resupplied to the load. There is no.
[0019]
As shown in FIG. 6, once the operator turns off the power switch pw, the second relay means odY is de-energized, so the second off contact Y1a and the third off contact Y2a are turned back on. When the abnormality detection switch Th is turned on from this state, the initial state shown in FIG. 1 is obtained. Therefore, when the operator turns on the power switch pw after eliminating the failure, power can be supplied again to the load as described with reference to FIG.
[0020]
FIG. 7 shows a state where a power failure occurs in the state of FIG. 2 (a state where power is supplied to the load).
Since the first relay means X is de-energized, the first off contact Xa is turned back on. When recovering from a power failure in this state, the state automatically returns to the state of FIG. 2, and power can be automatically resupplied to the load.
[0021]
For example, the load is a magnet coil (static magnetic field coil) of an MRI (Magnetic Resonanse Imaging) apparatus. Further, the abnormality detection switch Th is a thermistor switch that is turned on when a state where the magnet temperature is lower than a limit value is detected and turned off when a state where the magnet temperature is higher than the limit value is detected.
Then, if the magnet temperature exceeds a limit value due to some trouble, the power supply to the magnet coil is cut off, so that the magnet coil can be protected.
[0022]
【The invention's effect】
According to the power supply control circuit of the present invention, when an abnormality caused by some kind of failure is detected, the power supply to the load can be stopped to protect the load. Further, it is possible to prevent the power from being automatically resupplied to the load even if no abnormality is detected before the failure is resolved.
