本発明は電流遮断用の電磁式ブレーカに関するものでお
る。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electromagnetic breaker for interrupting current.
従来のこの種の電磁式ブレーカは、定格電流を越える電
流が流れた場合、定格電流を越えた電流の大きさに応じ
て暫時経過後、電流の遮断動作を行Δつでいた。In conventional electromagnetic breakers of this type, when a current exceeding the rated current flows, the current is interrupted after a period of time depending on the magnitude of the current exceeding the rated current.
上述した従来のブレーカは、警報装置が装着されていな
いので、定格電流を越える電流が流れた場合、何の予告
もなしに突然に電流が遮断されていた。The conventional breaker described above is not equipped with an alarm device, so if a current exceeding the rated current flows, the current is suddenly cut off without any prior notice.

、ブレーカの落ちる機会が増大していた。Automation of offices and factories in recent years (OA,
As automation (FA) progresses, if the power to computers, facsimile machines, word processors, etc. is suddenly cut off, important data will be lost. With the introduction of many different types of home appliances into the home, there was an increasing chance that breakers would trip due to overuse of electricity in air conditioners, electric kotatsus, microwave ovens, ceramic heaters, etc.

とを有している。In order to solve this problem, the electromagnetic breaker according to the present invention includes a detector that immediately detects the current when a certain proportion of the current flows with respect to the rated current capacity, and a and an alarm device that issues an alarm when it detects.
本発明にかいては、検出電流発生時の電流遮断前に過電
流を予め警報する。According to the present invention, an overcurrent warning is given in advance before the current is cut off when a detected current is generated.
次に本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.

悪の事態を回避することができる。In such a configuration, the rated current capacity of the breaker 2 is, for example, 30A. When a current of 90% of the rated current capacity of the breaker 2, in this case 27 A or more, flows, the current detector 1 detects this and notifies the alarm device 3 of the current. When the alarm device 3 is informed of this, it notifies the person by sounding an alarm buzzer and lighting an alarm lamp. Even if alarm device 3 is activated,
If the load current is not reduced and the load current exceeds 3OA, the breaker main body 2 is activated and the current is cut off after a while. When the alarm device 3 is activated, even if the load current exceeds 3OA, the load current is immediately reduced, thereby avoiding the worst situation for computers, etc., where the current is cut off.

In the figure, a current pickup coil 11 in a current detector 1 picks up current, rectifies it with a diode 12, smoothes it with a capacitor 13, and converts it into direct current. A threshold value for detection sensitivity is provided by the constant voltage diode 14. The resistors 15 and 16 act as current limiting resistors for the constant voltage diode 14, and also act as voltage dividing resistors and current limiting resistors for the voltage applied to the constant voltage diode 1T.
