摘要： The inverter according to the invention includes a control microcomputer including a protector circuit that stops the inverter when an anomaly is caused, a counter that counts the driving clock signals of the microcomputer from the instance at which the protector circuit starts working, and a conversion circuit that converts the clock signals counted by the counter to a numerical time expression in the time units and outputs the converted numerical time expression. The inverter according to the invention, manufacturable with low manufacturing costs and easy to operate, facilitates informing the installation manager of the period of time from the instance at which the inverter stopped due to an anomaly and such a cause, without impairing the time measurement precision.

摘要： An electromagnetic contactor in which neighboring main contact points have an interphase barrier between them. A concave section is provided at the inner wall face of the interphase barrier at the middle of the emission path of the arc gas that is generated from the opening and closing of a main contact point. The concave section allows the arc gas passing from an arc generation point to an emission window to be accumulated in the concave section, which acts as a container, thus reducing the rate at which the arc gas is emitted. As a result, the amount of heat dispersed from the arc gas to the interphase barrier due to heat transfer is increased, thus reducing the temperature of the arc gas flowing from the emission window, which suppresses damage to the wiring cable that would otherwise occur due to excessive heating of the main terminal onto which the arc gas flows, and fusion of the interphase barrier.
摘要翻译：电磁接触器，其中相邻的主接触点之间具有相间屏障。在从主接触点的开闭产生的电弧气体的发射路径的中间，在相间势垒的内壁面设置凹部。该凹部允许从电弧产生点通过发射窗的电弧气体积聚在作为容器的凹部中，从而降低电弧气体的发射速率。结果，由于传热而从电弧气体分散到相间屏障的热量增加，从而降低了从发射窗口流出的电弧气体的温度，从而抑制了否则将发生的布线电缆的损坏电弧气体流过的主要终端的过度加热，以及相间势垒的融合。

摘要： A circuit breaker has a molded case with a main case, a middle cover and a top cover being dividable from one another. The main case contains contactor sections, each including a stationary contactor and a movable contactor for a pole corresponding to each phase in a polyphase circuit, an arc-extinguishing device, an overcurrent tripping device actuating a tripping mechanism by detecting an overcurrent, and a zero-phase current transformer detecting a leak current. The middle cover has a partitioned recess for containing a switching mechanism and the tripping mechanism. Interpole partitions, surrounding the contactor section and the arc-extinguishing device, and a screen-like intermediate partition, isolating the contactor sections from the overcurrent tripping device, are formed with the middle cover laid on the main case. A wall with gas outlets for an arc gas is provided on the back of the arc-extinguishing devices.

摘要： A contactor device of a repulsion-type circuit breaker includes a first movable contactor with a first movable contact to be driven by an open-close mechanism; a fixed contactor; a second movable contactor having second and third movable contacts; a first contact spring for urging the first movable contactor toward the second movable contactor; and a second contact spring for urging the second movable contactor toward the first movable contactor and the fixed contactor. The first movable contactor, fixed contactor, and second movable contactor are arranged such that when an over-current flows, an electromagnetic repulsive force is generated so that the first and second movable contactors are rotated against the first and second contact springs to open between the first movable contact and the second movable contact and between the fixed contact and the third movable contact before the open-close mechanism opens the first movable contact.
