Description
【０００１】[0001]
感震器の小型化をはかり、従来の漏電遮断器に感震器を内臓した耐震漏電遮断器 を実現し、電磁接触器を不用とした感震制御による主回路の遮断を低コスト低価 格で可能とし、耐震漏電遮断器又は感震器のみ独立した漏電遮断器用感震器とし て耐震制御配電盤や耐震漏電分電盤として震災時の電気機器からの出火防止対策 として、広く、一般に提供できる。 We have realized a seismic-resistant earth leakage circuit breaker that incorporates a seismic sensor in addition to the conventional earth leakage circuit breaker in order to reduce the size of the seismic element. The seismic-resistant earth leakage circuit breaker or seismic shock absorber is an independent earth-leakage circuit breaker seismic sensor for seismic control panel and seismic-resistant earth leakage distribution board, which is widely and generally provided as a measure to prevent fires from electrical equipment during an earthquake. it can.

従来、配電盤や分電盤の主回路を感震器で制御する場合、漏電遮断器等の主幹ス イッチの二次側に電磁接触器を使用した。電磁接触器の容量は主幹スイッチの容 量に比例して大きく成り、部品や組立コストが高く成って、一般家庭の分電盤に は殆ど使われなかった。従来の感震器は機械構造の為、大きさや取付方向に制約 があり漏電遮断器の内部に取付は不可能であった。 Conventionally, when controlling the main circuit of a switchboard or distribution board with a seismic sensor, an electromagnetic contactor was used on the secondary side of the main switch such as an earth leakage breaker. The capacity of the electromagnetic contactor became large in proportion to the capacity of the main switch, and the parts and assembly costs were high, so it was hardly used for the distribution board of ordinary households. Due to the mechanical structure of conventional seismic sensors, there were restrictions on size and mounting direction, making it impossible to mount them inside the earth leakage breaker.

今度の阪神大震災での火災には、人々はなすすべくもなく、改めて消火活動の限 界を知らされました。火災によって多数の尊い人命を倒壊家屋の中から救出する 事なく焼失した。報道のなかで、火災の原因を幾つかあげていましたが、その中 で、電路復旧時に於ける倒壊家屋内の電気機器の発熱による火災も数件報道され ました。本考案が解決しようとする課題は、震災時に於ける電気機器からの出火 防止対策として、従来の感震器と電磁接触器による制御が、コスト価格の面から 殆ど採用されていないことから、低コスト低価格を目指し広く一般家庭の分電盤 に採用可能な感震器と耐震漏電遮断器の開発。 In the fire that followed the Great Hanshin Earthquake, people had no choice but to inform them of the limits of fire-fighting activities. Many precious lives were destroyed by the fire without being rescued from the collapsed house. Some of the causes of the fire were mentioned in the news report, and among them, several fires were reported due to the heat generated from the electrical equipment inside the collapsed house when the power line was restored. The problem to be solved by the present invention is that, as a measure to prevent fire from electrical equipment in the event of an earthquake, conventional control using a seismic sensor and an electromagnetic contactor is rarely adopted in terms of cost and price. Aiming at low cost and low price, we have developed a seismic sensor and seismic-resistant earth leakage circuit breaker that can be widely used in distribution boards for general households.
