Since remote control type circuit breakers and breakers are operated remotely, even if the circuit breakers and breakers are turned on by remote control, it is necessary to check whether the contacts are actually closed and the load side is energized. . For this reason, conventionally, as shown in Fig. 4, a current transformer C is inserted on the load side of the contact B of the circuit A inside the breaker, the secondary current is amplified by the amplifier D, and the external indicator lamp L is It was configured to light up. Such a current transformer C is useful even if it is installed in a general circuit or disconnector.

Further, when the rated current is flowing through the coil, the abnormal current detection electromagnet does not operate, but the magnetic flux of the coil is detected by the energization detection coil. Therefore, the presence or absence of rated energization can be detected without installing a current transformer in the electrical circuit as in the past, and since a energization detection coil is provided in the abnormal current detection electromagnet for tripping the mechanism, The number of parts when assembling the breaker does not increase, and the internal space of the breaker hardly increases. Furthermore, since the magnetic flux of the coil of the abnormal current detection electromagnet is detected, the magnetic flux is larger than that of a current transformer, so the detection ability is excellent.

る。 In the ON state shown in FIG. 1, when the rated current is applied, the coil 6 of the abnormal current detection electromagnet 7 is excited, but it does not operate because the plunger attraction force is smaller than the spring force of the return coil spring 16. The magnetic flux is detected by the energization detection coil 13. The energization indication is performed by amplifying this signal with an amplifier and lighting an external lamp. Also, when an overcurrent flows, the bimetal 9 is heated and bent, and the adjustment screw 9a pushes the trip link 28, and when a short circuit current (more than a certain current) flows, the coil 6
The plunger attraction force overcomes the spring force of the return coil spring 16, and the plunger 15 operates. Through this operation, the movable contact 23 is forcibly opened by the forced opening rod 18, and the movable rod 17 is pushed to push the trip link 28. As the trip link 28 rotates, the latch link 29 is unlatched and the shaft 25 becomes free, so that the movable contact 23 is supported by the link 22 and opened. Note that the reset is performed by turning off the handle 20 or by turning off the operating electromagnet 21 and turning the handle 20 off.

As described above, according to the circuit breaker and disconnector of this invention, since the abnormal current detection electromagnet is provided with the energization detection coil that interlinks with the magnetic flux when the coil of the abnormal current detection electromagnet is energized, it is different from the conventional one. As such, it is possible to detect the presence or absence of rated current without installing a current transformer in the electrical circuit, and because a current detection coil is installed in the abnormal current detection electromagnet for tripping the mechanism,
The number of parts when assembling the breaker does not increase, and the internal space of the breaker hardly increases. Furthermore, since the magnetic flux of the coil of the abnormal current detection electromagnet is detected, the magnetic flux is larger than that of a current transformer, so there is an effect that the detection ability is excellent.
