じる。Generally, in a lightning arrester (overvoltage protection device) using a discharge gap, a continuous current flows for at least half a wave (10 ms) after a lightning current passes as shown in FIG.
It is necessary to protect electronic equipment from the subsequent flow. By the way, there are some surge arresters with or without follow current cutoff. Even if it has the follow current cutoff performance, it does not necessarily have the sufficient follow current cutoff performance for cutting off the short-circuit current at the installation point. Further, even if the surge arrester has a follow-current cutoff function at the installation point, the surge arrester has a life in the number of operations, and if the life is exceeded, the follower cutoff cannot be performed. Therefore, in any case, a circuit breaker (overcurrent protection circuit breaker) for protecting the lightning arrester is required. When installing a protective protective circuit breaker, if the lightning arrester itself possesses a continuous current interrupting capability, the circuit breaker should not be activated as much as possible during the life of the arrester. If the circuit breaker performs the breaking operation at the same time as the lightning arrester, the annoyance that the circuit breaker must be turned on again each time the lightning arrester operates.

Description of the Related Art Conventionally, as an internal lightning protection device for protecting electronic devices and digital data from lightning surges and follow-up currents, the following techniques have been developed or found particularly as those relating to the present invention. There is. An internal lightning protection device in which an overvoltage protection device using a follow current breaker or a gap method without a follow current breaker capability and an overcurrent breaker equipped with the follow current breaker are connected in series. An internal lightning protection device provided with an overvoltage protection device provided with a continuous current interruption device for a specific finite time, and an overcurrent protection interruption device equal to or almost equal to the continuous current interruption time. An internal lightning protection device provided with an overvoltage protection device provided with an infinite time continuous current interruption device and an overcurrent protection interruption device having no instantaneous release device in a short-circuit current region. The lightning protection device can protect electronic devices and digital data from unexpected overcurrent such as lightning, and is useful in that respect.

夫、最終保障性が欠けていたといわざるを得ない。However, even if importance is attached to the purpose of protecting electronic devices and digital data, it can be said that it is the intent of an ordinary person to want to continue business without stopping power supply as much as possible. Therefore, as in the conventional example, a form in which the point of protection is always placed in the overcurrent protection circuit breaker should not be desired, and is sufficient as a means for protecting against abnormal current from the economic loss of power supply interruption. I cannot help saying that it lacked ingenuity and final security.

However, when the protection device reaches the end of its life, the overcurrent protection breaker cannot perform protection break in the short-circuit current region.

要であり、この点もまた課題のひとつである。SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and one of the problems is to prevent simultaneous operation of an overvoltage protection device and an overcurrent protection circuit breaker. Furthermore, not only to protect against overcurrent or overvoltage due to lightning surge and follow-up current, but also to prevent simultaneous operation of the overvoltage protection device and the overcurrent protection circuit breaker, which shortens the current interruption time and reduces the work delay due to the use of electronic devices. Preventing is also an issue. In order to achieve this purpose, it is necessary that the abnormality of the overcurrent protection breaker can always be monitored from the outside, and this is also one of the problems.

The simultaneous interruption is prevented by configuring an overcurrent protection interruption device provided with time.

遮断容量を持っている。The time-delaying operation instantaneous release device is provided with a current interrupting means that is equal to or more than a ground fault or a short circuit current at the installation position of the overvoltage protection device. Further, there is a feature that the time until the start of operation of the time delay action instantaneous release device is longer than the continuous current interruption time of the overvoltage protection device (2). Therefore, the overcurrent protection breaker has a trip time longer than a predetermined continuous-current breaking time of the overvoltage protection device and a breaking capacity equal to or greater than a ground fault or a short-circuit current at the installation position of the overvoltage protection device.

If it loses its breaking ability or reaches the end of its life, the follow-up current will be broken by the overcurrent protection breaking device. The overcurrent protection breaker is provided with an operation alarm device so that the operation state can be notified to the outside.

Only in this case, the overcurrent protection interrupting device (3) for protection of the backup equipment operates to interrupt the overcurrent. In other words, the overcurrent protection breaker (3) does not operate for all overcurrents, and is configured as an internal lightning protection device having a function of breaking off when it should. Due to such a configuration, the function of the entire device guarantees durability and safety in two stages.
