Description
本発明は、例えば電気解放式ブレーキの電磁石のコイルに交流電源から電流を供給するための整流回路に関する。 The present invention relates to a rectifier circuit for supplying current from an AC power source to an electromagnet coil of an electric release brake, for example.
電気解放式ブレーキ、例えばエレベータの安全ブレーキは、一般に、ばねで押し込まれて係合するブレーキからなる。この点に関連して「解放」とは、ブレーキが電流の作用によって引き外され又は解除されることを意味する。電磁石はブレーキを解除するために設けられている。電磁石は接極子に働くばね力に対抗する。ところが電磁石が電流を遮断されると、直ちにばねがブレーキを戻して係合させる。従ってブレーキが働く機械設備の使用時間の大部分で電磁石のコイルが励磁されていなければならず、このため絶えず電流を供給することが必要である。これは地域の給電網に接続することによって行われるのが通例である。機械設備の近辺で利用可能な地域給電網の電圧は、幾つかの異なる標準値を有するのが通例である。例えば400V三相電流又は強電流給電網もしくはヨーロッパの230/250V家庭用給電網もしくは米国でみられる低圧の110V家庭用給電網が取り上げられる。利用可能なあらゆる電圧及びブレーキ電力のために、電磁解放式ブレーキの製造元は適合するコイルを供給しなければならない。このため製品の大規模な在庫保持が必要であり、この製品を製造、保持及び保守しなければならない。 Electrically released brakes, such as elevator safety brakes, generally consist of a brake that is pushed in and engaged by a spring. “Release” in this context means that the brake is tripped or released by the action of an electric current. An electromagnet is provided to release the brake. The electromagnet counters the spring force acting on the armature. However, as soon as the electromagnet cuts off the current, the spring returns the brake to engage. Therefore, the electromagnet coil must be energized for most of the usage time of the mechanical equipment where the brakes operate, and therefore it is necessary to supply current constantly. This is typically done by connecting to a local power grid. The voltage of the local power supply network available in the vicinity of the mechanical equipment typically has several different standard values. For example, 400V three-phase current or high current power supply network, European 230 / 250V home power supply network, or low voltage 110V home power supply network found in the United States. For every voltage and brake power available, the manufacturer of the electromagnetic release brake must supply a matching coil. This requires a large inventory of the product, which must be manufactured, maintained and maintained.
この様々な電源電圧の問題は刊行物、ドイツ特許公報DE19740016（対応米国特許第6291952号）で言及されている。この刊行物は、コイルを通る平均電流量を電子スイッチによって制限するアセンブリを記述する。コイルの磁石効果は巻線を流れる電流に比例するから、平均電流を調節することによって磁界強度も、回路全体に印加される電圧に関係なく、ブレーキの解放のために必要な目標値に調整される。しかし、このアセンブリの欠点は、ブレーキの大きさごとに特別の限界電流を設定しなければならないことである。回路は、コイルの実効抵抗が上昇すると起こる熱過負荷に対して保護を与えない。コイルは長い期間にわたって励磁され、従って温度上昇するのが通例である。温度上昇によってその抵抗が増加する。ところがコイル電流が一定に保たれ、コイルが温度上昇すると、コイルで変換される電力も上昇し、このためコイルの温度がさらに高くなる。電流の一定保持のためにさらに高い電圧が必要である。上昇する電力と電圧は急速にコイルの破損を招く恐れがある。 These various supply voltage problems are mentioned in the publication German Patent Publication DE 19740016 (corresponding US Pat. No. 6,291,952). This publication describes an assembly that limits the average amount of current through the coil by means of an electronic switch. Since the magnet effect of the coil is proportional to the current flowing through the winding, by adjusting the average current, the magnetic field strength is also adjusted to the target value required for brake release, regardless of the voltage applied to the entire circuit. The However, the disadvantage of this assembly is that a special limit current has to be set for each brake size. The circuit does not protect against thermal overload that occurs when the effective resistance of the coil increases. The coil is typically energized over a long period of time, and thus typically increases in temperature. The resistance increases with increasing temperature. However, when the coil current is kept constant and the temperature of the coil rises, the power converted by the coil also rises, and the coil temperature further increases. Higher voltages are required to keep the current constant. Increasing power and voltage can cause rapid coil damage.
本発明の課題は様々な電源電圧で使用できる電磁解放式ブレーキの給電のための整流回路である。すべての電圧に対して同じ電磁コイル、すべての大きさの電磁石に対して同じ整流回路を使用できることを意図する。 An object of the present invention is a rectifier circuit for feeding an electromagnetic release brake that can be used at various power supply voltages. It is intended that the same electromagnetic coil for all voltages and the same rectifier circuit for all sized electromagnets can be used.
本発明の第一の観点によれば、本発明は下記の部品、即ち交流電源に接続するための入力端子、該入力端子に接続されるとともに供給される交流電流に基づき直流電圧を発生する整流器の整流回路及びコイルに接続される直流電圧を整流回路から取り出すことができる出力端子を有する、コイルに使用電流を供給するための回路において、該出力端子に印加される電圧を制御するために出力端子に電源制御回路が配置されており、該電源制御回路が制御出力線と、出力端子に被制御電圧を維持するために整流器がより多くの電流を必要とする場合に、出力線に要求信号を印加することができる内部回路とを有し、かつ整流素子が電圧制限回路を有し、電圧制限回路は電源制御回路の制御出力線に接続され、要求信号が受領されたとき、出力端子へ電流を通すことを特徴とする回路を提供する。 According to a first aspect of the present invention, the present invention provides the following components: an input terminal for connection to an AC power supply; a rectifier that generates a DC voltage based on an AC current that is connected to and supplied to the input terminal. A circuit for supplying a working current to a coil having an output terminal capable of extracting a DC voltage connected to the rectifier circuit and the coil from the rectifier circuit, an output for controlling a voltage applied to the output terminal When a power supply control circuit is arranged at the terminal, and the power supply control circuit requires more current for the control output line and the rectifier to maintain a controlled voltage at the output terminal, a request signal is output to the output line. And the rectifier element has a voltage limiting circuit, the voltage limiting circuit is connected to the control output line of the power supply control circuit, and when the request signal is received, the output terminal Providing a circuit, characterized in that pass current to.
発明の第二の観点によれば、本発明は、入力端子に接続されるとともに周期的に変化する直流電圧を発生する整流器の整流回路と、該整流器が発生した直流電圧をコイルに供給するための出力端子と、直流電流を随時断続することができる電子弁／スイッチと、該出力端子に接続され、該電子弁又はスイッチの遮断時間の間、コイルを通る電流の流れを維持するフリーホイーリング回路のフリーホイーリング・ダイオードと、該出力端子に接続され、コイルに印加される直流電圧を測定し、又は他の測定された電圧（例えば入力電圧、中間回路電圧、弁−スイッチ電圧等）から計算し又は導き出し、コイルに印加される直流電圧を一定に保つために電子弁又はスイッチを制御する制御回路と、非常解放のために該フリーホイーリング回路を切断することができるコイル電源部の機械／電子スイッチとを有する、種々の使用電圧を有する交流電源に接続するコイルの操作のための回路を提供する。 According to a second aspect of the invention, the present invention provides a rectifier circuit for a rectifier that is connected to an input terminal and generates a periodically changing DC voltage, and for supplying the DC voltage generated by the rectifier to a coil. Output terminal, an electronic valve / switch capable of interrupting DC current at any time, and a freewheeling connected to the output terminal to maintain current flow through the coil during the shut-off time of the electronic valve or switch Measure the DC voltage applied to the coil connected to the output terminal and the freewheeling diode of the circuit, or from other measured voltages (eg input voltage, intermediate circuit voltage, valve-switch voltage, etc.) A control circuit that calculates or derives and controls the electronic valve or switch to keep the DC voltage applied to the coil constant, and the freewheeling circuit for emergency release. And a mechanical / electronic switch coil power supply unit which can be, to provide a circuit for operating the coil connected to an AC power source having a different operating voltage.
本発明に基づくアセンブリは、コイルに印加される電圧を制御する。即ちコイルの温度が上昇すれば、コイルで変換される電力は抵抗の関数（P=U2/R）として低下する。それによってコイルの発熱効果が減少する。またコイルの電圧が安定化されるから、様々な網電圧又は電源電圧及びコイル電流の広い範囲にわたってこの回路を使用することができる。またアセンブリは、あらゆる目標電流に対して電流／電圧組合せごとに別個のユニットでなく、整流器とコイル電圧からなるただ１つの改装用セットを作ればよいという利点がある。それによって製造及び保持される部品の数の大幅な減少が得られる。様々な目標コイル電流を考えても、ただ１つの整流回路で間に合う電流範囲はかなり広い。発明の別の観点は、好ましくは整流器とブレーキコイルからなる改装又は増設用セット並びに整流器、コイル及び所属のブレーキ部品、例えばプレーキ板及びブレーキを掛けるためのばねからなるブレーキ一式である。このようなブレーキ自体の設計は周知であり、本願出願人の名義で出ている幾つかの特許公報に見られる。 The assembly according to the invention controls the voltage applied to the coil. That is, if the coil temperature increases, the power converted by the coil decreases as a function of resistance (P = U 2 / R). Thereby, the heating effect of the coil is reduced. Also, since the coil voltage is stabilized, the circuit can be used over a wide range of various network or power supply voltages and coil currents. The assembly also has the advantage that only one retrofit set of rectifier and coil voltage need be created for each target current, rather than a separate unit for each current / voltage combination. This results in a significant reduction in the number of parts that are manufactured and held. Even if various target coil currents are considered, the current range in time with only one rectifier circuit is quite wide. Another aspect of the invention is a retrofit or expansion set, preferably consisting of a rectifier and a brake coil, and a set of brakes consisting of a rectifier, coil and associated brake components, such as a brake plate and a spring for braking. The design of such a brake itself is well known and can be found in several patent publications issued in the name of the applicant.
次に添付の図面を参照して、本発明の幾つかの実施形態を説明する。 Several embodiments of the present invention will now be described with reference to the accompanying drawings.
図１は部分制御ブリッジを示す。測定・制御素子は、コイルY1に目標直流電圧が印加されるように電子スイッチT1及びT2を制御する。スイッチS1は任意の直流側切断のために使用される。電圧制御は位相遅角制御、位相進角制御又はパルス幅変調（PWM）によって行うことができる。スイッチS1は任意の直流側切断のために使用される。 FIG. 1 shows a partial control bridge. The measurement / control element controls the electronic switches T1 and T2 so that the target DC voltage is applied to the coil Y1. The switch S1 is used for arbitrary DC side disconnection. The voltage control can be performed by phase retardation control, phase advance control, or pulse width modulation (PWM). The switch S1 is used for arbitrary DC side disconnection.
こうして図１のアセンブリでは整流ブリッジの正側の半分でSCR（シリコン制御整流素子）の電子スイッチT1及びT2が整流器を代行する。コイル電圧の目標値を維持するために電流が必要なときは、SCRのゲート電極が励起されるから、ブリッジ整流器が導通する。 Thus, in the assembly of FIG. 1, SCR (silicon controlled rectifier) electronic switches T1 and T2 act as rectifiers on the positive half of the rectifier bridge. When a current is required to maintain the coil voltage target value, the SCR gate electrode is excited and the bridge rectifier conducts.
図２はブリッジ整流回路を示す。目標直流電圧がコイルY1に印加されるように、測定・制御素子が交流電圧側で電子スイッチT1に作用する。電圧制御は位相遅角制御、位相進角制御又はパルス幅変調によって行うことができる。スイッチS1は任意の直流側切断のために使用される。 FIG. 2 shows a bridge rectifier circuit. The measuring / controlling element acts on the electronic switch T1 on the AC voltage side so that the target DC voltage is applied to the coil Y1. The voltage control can be performed by phase retardation control, phase advance control, or pulse width modulation. The switch S1 is used for arbitrary DC side disconnection.
図２の配列では、必要に応じて測定・制御素子の制御に従ってブリッジ整流器に電流を供給するために、トライアック又はその他の電気ACスイッチ素子が交流電源の位相の1つに直列に接続されている。 In the arrangement of FIG. 2, a triac or other electrical AC switch element is connected in series with one of the phases of the AC power source to supply current to the bridge rectifier as required under the control of the measurement and control elements. .
図３はブリッジ整流器を示す。測定・制御素子はコイルY1に目標直流電圧が印加されるように、直流電圧側の電子スイッチT1を制御する。電圧制御は位相遅角制御、位相進角制御又はパルス幅変調によって行うことができる。スイッチS1は任意の直流側切断のために使用される。 FIG. 3 shows a bridge rectifier. The measurement / control element controls the electronic switch T1 on the DC voltage side so that the target DC voltage is applied to the coil Y1. The voltage control can be performed by phase retardation control, phase advance control, or pulse width modulation. The switch S1 is used for arbitrary DC side disconnection.
従ってこのアセンブリでは交流入力がブリッジ整流器に直接印加される。電子スイッチ、例えばIGBT（絶縁ゲート型バイポーラ・トランジスタ）はコイルに印加される電圧を直流側で測定・制御素子の信号に従って制御する。 In this assembly, therefore, an AC input is applied directly to the bridge rectifier. An electronic switch such as an IGBT (Insulated Gate Bipolar Transistor) controls the voltage applied to the coil on the direct current side in accordance with the signal of the measurement / control element.
上記のすべての実施形態で示した回路では、電流供給の遮断の後に継続する電流の流れを保証するダイオードがコイルと並列に配置されている。コイル電流の最大電流低下を保証するために切断されるスイッチを、このフリーホイーリング・ダイオードと直列に任意に配置することができる。最後に、コイルの逆電圧の過度の上昇を阻止し、許容電圧を超えない保護回路が組み込まれる。 In the circuits shown in all of the above embodiments, a diode is arranged in parallel with the coil to guarantee a current flow that continues after the interruption of the current supply. A switch that is disconnected to ensure maximum coil current reduction can optionally be placed in series with this freewheeling diode. Finally, a protection circuit is incorporated that prevents an excessive increase in the reverse voltage of the coil and does not exceed the allowable voltage.
ブロック構成図の「測定・制御素子」は、出力電圧又は出力電圧をそれから計算し又は導き出すことができる他の電圧（例えば入力電圧、中間回路電圧、弁−スイッチ電圧等）を検出するためのRC素子と分圧器並びに出力電圧の高さに応じて電子スイッチを制御する評価回路である。それは例えば演算増幅器又はマイクロプロセッサによって実現される。 “Measurement and control element” in the block diagram is an RC for detecting the output voltage or other voltages from which the output voltage can be calculated or derived (eg, input voltage, intermediate circuit voltage, valve-switch voltage, etc.) It is an evaluation circuit that controls the electronic switch in accordance with the element, voltage divider, and output voltage level. It is realized for example by an operational amplifier or a microprocessor.
コイルY1は、好ましくは温度変化に基づきその実効抵抗を変化させるコイルにほかならないから、コイル電圧が一定に保たれればコイル電流は低下する。 Since the coil Y1 is preferably a coil that changes its effective resistance based on a temperature change, the coil current decreases if the coil voltage is kept constant.
上記のすべての実施形態について、過励磁及び／又は保持電圧の減少を得るために、制御電圧を任意に上方又は下方調整することが考えられる。磁界を可能な限り急速に形成するために初期励磁でコイルを過励磁し、完全な励磁の後に低い電圧で励磁を保つのが通例である。この回路構成は特に50Hz又は60Hz（例えば米国）を含む任意の電源周波数に適している。3:1の規模の範囲で電源電圧を操作できることが判明した。 For all the above embodiments, it is conceivable to adjust the control voltage arbitrarily upwards or downwards in order to obtain overexcitation and / or reduction of the holding voltage. In order to form the magnetic field as quickly as possible, the coil is usually overexcited with initial excitation and the excitation is kept at a low voltage after complete excitation. This circuit configuration is particularly suitable for any power supply frequency including 50 Hz or 60 Hz (eg USA). It was found that the power supply voltage can be manipulated in the range of 3: 1 scale.
