Description
本発明は、充電発電機の冷却空気圧によって発電機励磁回路及び出力回路を自動的に開閉するものである。 The present invention automatically opens and closes the generator excitation circuit and the output circuit by the cooling air pressure of the charging generator.
充電発電機の場合、交流発電機の励磁電流で出力電圧及び電流を制御し、交流を整流して出力するのが一般的である。
この場合、出力電圧・電流の制御が容易であるという特徴を持っている。
In the case of a charging generator, the output voltage and current are generally controlled by the excitation current of the AC generator, and the AC is rectified and output.
In this case, the output voltage and current can be easily controlled.
しかし、励磁電力が必要なことから発電機の回転が停止した場合、発電電力が発生せず、蓄電池から励磁電流が流れ放電されることになる。 However, when the rotation of the generator is stopped because excitation power is required, no generation power is generated and excitation current flows from the storage battery and is discharged.
充電用発電機が所定の回転数に達しない場合励磁電流を遮断するには二つの方法がある。 There are two ways to cut off the excitation current when the charging generator does not reach the predetermined rotational speed.
その一つは、回転子に遠心スイッチを設ける方法である。
この方法は歴史がありかつ現在も単相電動機の起動用蓄電池回路の開閉に使用されているが回転子にスイッチが取り付けているのでスリップリングが必要で機械的機構が複雑である。
One of them is a method of providing a centrifugal switch on the rotor.
This method has a history and is still used for opening and closing a storage battery circuit for starting a single-phase motor. However, since a switch is attached to a rotor, a slip ring is required and a mechanical mechanism is complicated.
もう一つの方法は、電子的に回転数を感知し自動的に励磁電流を遮断する方法で現在主流である。この感知回路は半導体なので数ミリアンペア以上の電流を消費するのが欠点である。 The other method is currently mainstream in that the rotational speed is electronically detected and the excitation current is automatically cut off. Since this sensing circuit is a semiconductor, it has a disadvantage that it consumes a current of several milliamperes or more.
このように、発電機が停止した場合蓄電池の蓄電容量を消費してしまうという欠点がある。
さらに、出力回路が整流器を通して蓄電池に接続されているので数ミリアンペアの漏洩電流が発生し、数ヶ月で蓄電池容量の大部分を消費してしまうことになる。
Thus, there exists a fault that the storage capacity of a storage battery will be consumed when a generator stops.
Furthermore, since the output circuit is connected to the storage battery through a rectifier, a leakage current of several milliamperes is generated, and a large part of the storage battery capacity is consumed in several months.
充電用発電機停止中の励磁電流と整流回路の漏洩電流及び電圧電流制御用半導体の全ての消費電流をゼロにするために本発明装置を考案した。 The device of the present invention has been devised in order to make all of the current consumed by the exciting current, the leakage current of the rectifier circuit and the voltage / current control semiconductor when the generator for charging is stopped zero.
発電機が停止中に励磁回路と充電回路を遮断する安価な制御装置を用いることを検討した結果、発電機本体の冷却空気圧を感知し、発電機の出力回路と励磁回路を開閉制御することにした。 As a result of investigating the use of an inexpensive control device that shuts off the excitation circuit and charging circuit while the generator is stopped, the cooling air pressure of the generator body is sensed and the output circuit and excitation circuit of the generator are controlled to open and close. did.
発電機のほとんどは発電機本体に組み込まれている冷却ファンによる空冷方式をとっている。したがって、発電機が充分に発電できる回転数かどうかは発電機の冷却空気圧力を感知することによって可能である。 Most generators use an air cooling system with a cooling fan built into the generator body. Therefore, it is possible to detect whether the generator can sufficiently generate electric power by sensing the cooling air pressure of the generator.
風圧センサは圧力の選択及び遅延時定数の選択も容易でその他の制御装置に比べ格段の低価格で信頼性も確保できる。
また、燃料槽搭載型内燃機関では燃料切れで機関停止のこともあり、機関停止時の放電防止に充電回路自動開閉装置は非常に有効である。
The wind pressure sensor can easily select a pressure and a delay time constant, and can ensure reliability at a much lower price than other control devices.
Further, in a fuel tank mounted internal combustion engine, the engine may stop due to running out of fuel, and the charging circuit automatic switching device is very effective in preventing discharge when the engine is stopped.
通常、蓄電池の充電には数時間以上掛かるときがあり、人間による連続監視は非常に困難であることから励磁回路及び主回路の自動開閉装置は蓄電池の放電防止に非常に有効な手段である。
解決しようとする問題点は、発電機の回転数が低下または停止した場合に充電発電機は発電電力を発生できず、励磁電流が蓄電池から供給され蓄電池が放電される点にある。 The problem to be solved is that when the rotational speed of the generator is reduced or stopped, the charging generator cannot generate generated power, and the exciting current is supplied from the storage battery and the storage battery is discharged.
本発明は、充電用発電機の回転が所定の回転数以上になった時のみ充電用発電機出力と蓄電池を結合する機能を有し、励磁電流及び整流回路の漏洩電流の消費を自動的に防止することを最も主要な特徴とする。 The present invention has a function of combining the output of the charging generator and the storage battery only when the rotation of the charging generator reaches a predetermined number of revolutions or more, and automatically consumes the excitation current and the leakage current of the rectifier circuit. Preventing is the main feature.
本発明の充電発電機は、充電回路及び励磁回路を充電用発電機が出力できる回転数以上の回転数になったときのみ蓄電池に接続し、蓄電池の放電を防止するという利点があり、かつ物理的に感知するのでセンサの監視中の電力消費はゼロである。 The charging generator of the present invention has an advantage that the charging circuit and the excitation circuit are connected to the storage battery only when the number of rotations is equal to or higher than the number of rotations that the charging generator can output, and the discharge of the storage battery is prevented. Power consumption during sensor monitoring is zero.
充電発電機の冷却空気の圧力を風圧センサで感知し、電磁接触器により充電用発電機出力回路と充電用発電機励磁回路を蓄電池に自動的に開閉接続することにより無駄な励磁電流と整流回路の漏洩電流の防止という目的を、最小の部品点数と経費で実現した。 By detecting the pressure of the cooling air of the charging generator with a wind pressure sensor and automatically opening and closing the generator output circuit for charging and the generator excitation circuit for charging to the storage battery by an electromagnetic contactor, useless excitation current and rectifier circuit The purpose of preventing leakage current was realized with the minimum number of parts and cost.

４風圧センサは充電用発電機の冷却空気圧を感知し、充電発電機がある一定回転数以上に達したとき閉信号を発し、ある一定回転数以下に降下すると開信号を発する。 The 4-wind pressure sensor senses the cooling air pressure of the charging generator, and issues a closing signal when the charging generator reaches a certain number of revolutions or more, and issues an opening signal when the charging generator falls below a certain number of revolutions.
４風圧センサの信号を受け５電磁接触器は開閉制御され、充電用発電機出力回路と励磁回路を蓄電池に自動的に接続する。 The 5 electromagnetic contactors are controlled to open and close in response to signals from the 4 wind pressure sensors, and the charging generator output circuit and the excitation circuit are automatically connected to the storage battery.
図２は、本発明装置の２実施例の制御回路図であって、１は原動機、２は充電用発電機、３は蓄電池、４は風圧センサ、５は電磁接触器である。 FIG. 2 is a control circuit diagram of two embodiments of the apparatus of the present invention, wherein 1 is a prime mover, 2 is a generator for charging, 3 is a storage battery, 4 is a wind pressure sensor, and 5 is an electromagnetic contactor.
４風圧センサは充電用発電機を駆動する原動機が空冷式の場合原動機の冷却空気圧を感知し、原動機がある一定回転数以上に達したとき閉信号を発し、ある一定回転数以下に降下すると開信号を発する。 4 The wind pressure sensor detects the cooling air pressure of the prime mover when the prime mover that drives the charging generator is air-cooled, and issues a close signal when the prime mover exceeds a certain number of revolutions, and opens when it falls below a certain number of revolutions. Send a signal.
このような制御回路を採用したので、操作者が持ち場を離れていて原動機が燃料切れ等により機関が停止した場合でも自動的に充電用発電機の励磁回路を遮断しかつ充電用発電機の出力回路も遮断するので、蓄電池の無駄な電流を阻止でき、蓄電池の放電防止に効果がある。 Since such a control circuit is adopted, even when the operator is away from the office and the engine stops due to the engine running out of fuel etc., the excitation circuit of the charging generator is automatically shut off and the output of the charging generator is output. Since the circuit is also cut off, it is possible to prevent useless current of the storage battery and to prevent discharge of the storage battery.
原動機を蓄電池の電力で起動する形態がセルモーター始動であるが、１ヶ月以上運転しない機会が近年多発し、所謂バッテリー上がりを起こす。
これを防止するため、電力を消費しないセンサで充電回路を自動的に開閉することによりバッテリー上がりを防止できる。
したがって、本発明は一般車両にも応用できる。
A mode of starting the motor with the electric power of the storage battery is a cell motor start. However, in recent years, there are many occasions when the motor is not operated for more than one month, and so-called battery exhaustion occurs.
In order to prevent this, the battery can be prevented from running up by automatically opening and closing the charging circuit with a sensor that does not consume power.
Therefore, the present invention can also be applied to general vehicles.
