Description
【考案の詳細な説明】 本案は、家庭電気機器を含む一般電気機器に印加される電圧を負荷中に適正な 値に補正するために、高速応答の電圧切換器の出力を入力電源と直列に接続した 電源に関する。DETAILED DESCRIPTION OF THE INVENTION In order to correct the voltage applied to general electric appliances including household electric appliances to a proper value during a load, the present invention puts the output of a fast response voltage switch in series with an input power source. Regarding the connected power supply.
今日の商用電源はほぼAC100V〜AC110Vの範囲で変動し、自家発電 の場合は変動範囲がもっと大きいこともある。一般電気機器の使用電圧の許容範 囲はAC90V〜AC110Vであるが、AC90Vの電源においても十分に使 用可能である。電気機器の使用電圧はその許容範囲においてできる限り小さい方 が消費電力も小さく省エネルギー対策になる。 Today's commercial power supplies fluctuate in the range of approximately AC100V to AC110V, and in the case of private power generation, the fluctuation range may be larger. The permissible range of operating voltage for general electric equipment is AC90V to AC110V, but it can be sufficiently used for AC90V power supply. If the operating voltage of an electric device is as small as possible within the allowable range, the power consumption will be small and energy saving measures will be taken.
また商用電源や自家発電において、ときにはその範囲を大きく越えて過電圧や 低電圧が一般電気機器に印加され、機器に悪影響与えることもある。 In commercial power sources and in-house power generation, overvoltages and low voltages are sometimes applied to general electric equipment over a large range, which may adversely affect the equipment.
またモータなどで動作する電動器具や電動装置及び電動機械などはその電源ス イッチを投入したままで無負荷のことも多い、すなわち間欠動作をしていて使用 していないことも多く見られる。この場合、無負荷や軽負荷のときはモータの電 圧を下げても設備に悪影響をあたえないので電圧を下げた分だけ省エネルギーに なる。 In addition, electric appliances, electric devices, electric machines, etc. that operate with motors are often unloaded with the power switch still on, that is, they are often used intermittently and not in use. In this case, if there is no load or light load, the equipment will not be adversely affected even if the motor voltage is lowered, so the amount of energy saved will be as much as the reduced voltage.
本案は、以上の問題を解決するため考案されたもので、この実施例を図1−( a)について説明すれば、商用電源または自家発電の交流電源と負荷Lとの間に 高速応答型電圧切換器2の出力を入力端子1と出力端子3を通して直列に接続す る。 The present invention was devised to solve the above problems. If this embodiment is described with reference to FIG. 1- (a), a high-speed response type voltage is provided between a commercial power source or an AC power source for private power generation and a load L. The output of the switch 2 is connected in series through the input terminal 1 and the output terminal 3.
この構成において、負荷電圧E3はE3=E1−E2となる。電圧E2は、高 速応答型電圧切換器2によって零を含む任意の値に選ぶことができる。省エネル ギー対策の場合、電源電圧E1が通常の範囲にあるときは、一般電気機器の使用 電圧E3を電源電圧E1より低い電圧となるようにし、電源電圧E1が通常より 低下したときには電圧E2を零に切り換えて、E3=E1またはE3≒E1とな るように動作する。 In this configuration, the load voltage E3 is E3 = E1-E2. The voltage E2 can be selected to any value including zero by the high-speed response type voltage switch 2. As a measure for energy saving, when the power supply voltage E1 is within the normal range, the working voltage E3 of the general electric equipment is set to be lower than the power supply voltage E1, and when the power supply voltage E1 is lower than the normal value, the voltage E2 is changed. Switch to zero and operate so that E3 = E1 or E3≈E1.
過電圧及び低電圧対策の場合、電源電圧E1が通常の範囲にあるときは、E3 =E1またはE3≒E1またはE3=E1−E2とするが、電源電圧E1が通常 より大きく低下したときにE3=E1+E2とし、電源電圧E1が通常より過大 になったときはE3=E1−E2となるように動作する。 As a measure against overvoltage and low voltage, when the power supply voltage E1 is in the normal range, E3 = E1 or E3≈E1 or E3 = E1−E2 is set, but when the power supply voltage E1 is much lower than usual, E3 = E1 + E2 is set, and when the power supply voltage E1 becomes higher than usual, the operation is performed so that E3 = E1-E2.
またモータの節電対策の場合、無負荷や軽負荷のときはモータの入力電流は小 さくなっているが、モータに負荷がかかると電流が増える。図1−(b)に示す ように負荷電流Iを電流検出器CTで検出し、電流Iが小さい間はモータへの印 加電圧を下げ電流Iが上がり始めたときにモータ印加電圧も同時に上げる。この ようにすると連続全負荷運転をしていないモータに対しては大きな節電になる。 Also, as a measure to save power in the motor, the input current of the motor is small when there is no load or light load, but the current increases when a load is applied to the motor. As shown in Fig. 1- (b), the load current I is detected by the current detector CT, and while the current I is small, the applied voltage to the motor is decreased and when the current I begins to increase, the motor applied voltage is also increased at the same time. . This saves a lot of power for a motor that is not in continuous full-load operation.
これら切換動作は切換時に機器に悪影響を与えないために数ミリ秒以下の高速 応答で行う。 These switching operations are performed with a high-speed response of a few milliseconds or less in order not to adversely affect the equipment during switching.
以上のことはAC200V系統、単相三線式、三相四線式または三相回路にお いても同様の効果が得られる。 The same effect can be obtained in the AC200V system, single-phase three-wire system, three-phase four-wire system, or three-phase circuit.
この補正電源の外形としては、図2−(a)に示すように延長コンセントの形 で使用しても便利である。差込みプラグ5、差込みコンセント6は共に3極にな っているが2極のものであってもかまわない。また電源入力の部分が差込みプラ グでなく端子台やコネクターであっても、また出力の部分が差込みコンセントで なく端子台やコネクターであってもかまわない。また壁取り付けタイプとして使 用することもできる。 As the external shape of this correction power source, it is convenient to use it in the form of an extension outlet as shown in Fig. 2- (a). Both the insertion plug 5 and the insertion outlet 6 have three poles, but they may have two poles. Also, the power input part may be a terminal block or connector instead of a plug, and the output part may be a terminal block or connector instead of a plug socket. It can also be used as a wall mount type.
図2−(b)に示すように入出力ともに端子台であっても便利である。 It is convenient to use a terminal block for both input and output as shown in FIG.
またこの補正電源を安全対策のため分電盤内に収納して使用することもできる 。 In addition, this compensating power supply can be stored in the distribution board for safety.
