摘要： An electric circuit 100 includes a power line 13 to supply electric power from a power source 11 to a load 12, and a monitor line 14 electrically independent from the power line 13 to detect temperature of the heat source. The monitor line 14 has a breaker 1 connected thereon in series. The breaker 1 includes a fixed contact, a movable piece having a movable contact and pressing the movable contact so as to contact the fixed contact, and a thermally actuated element deforming with temperature changes to actuate the movable piece so that the movable contact is spaced apart from the fixed contact.

摘要： A circuit interrupter includes a first set of contacts connected in series with a second set of contacts, with both sets of contacts configured to open and close simultaneously. First and second arc extinguishers are associated with the first and second sets of contacts, respectively. A moveable permanent magnet moves as the sets of contacts simultaneously open and close, the moveable magnet generating a moveable magnetic field, a first stationary permanent magnet associated with the first arc extinguisher, the first stationary magnet generating a first stationary magnetic field, where the first stationary magnetic field and the moveable magnetic field are additive, and a second stationary permanent magnet associated with the second arc extinguisher, the second stationary magnet generating a second stationary magnetic field, where the second stationary magnetic field and the moveable magnetic field are also additive.

摘要： An apparatus for reconfiguring a high-voltage circuit. The apparatus has a planar substrate, a non-conductive arm comprising a first contact and a rotary actuator having a body fixed to the substrate and a rotatable element fixed to the arm. The actuator is configured to selectably rotate the arm between a first position and a second position relative to the substrate. The apparatus also has a second contact fixed to the substrate such that the first contact makes conductive contact with the second contact when the arm is in the first position. The apparatus has a breakdown voltage that is greater than or equal to 500V.

摘要： A control system is designed to control an interrupter. The interrupter is started by a startup current to interrupt a main electric circuit. The startup current flows through an auxiliary electric circuit and has a current valve equal to or greater than a predetermined value. The control system includes a driving unit and a driven unit. The driving unit includes an intermediate electrical path to be connected to the main electric circuit. The driven unit is to be connected to the auxiliary electric circuit. When an abnormal current having a current value equal to or greater than a prescribed value flows through the intermediate electrical path, the driving unit uses, as a drive source for driving the driven unit, the abnormal current flowing through the intermediate electrical path. The driven unit supplies the auxiliary electric circuit with the startup current by being driven by the driving unit.

摘要： A double breaker switch comprises a contact bridge connected to an actuator at a connection point, a first fixed contact, and a second fixed contact. The contact bridge includes a first bridge contact connected to the connection point by a first arm and a second bridge contact connected to the connection point by a second arm. The second arm is longer than the first arm. The first bridge contact electrically connects with the first fixed contact at a first contact point in a closed state of the double breaker switch. The second bridge contact electrically connects with the second fixed contact at a second contact point and a third contact point in the closed state of the double breaker switch.

摘要： A circuit breaker includes: fixed contact points; and a moving contact assembly. The moving contact assembly includes: a shaft; a moving contact that is held in the shaft; and springs that apply torque to the moving contact. The shaft includes: stopping faces that are formed in a direction opposite to the direction in which the moving contact rotates; and guiding faces that are curved from the stopping faces. The moving contact includes: first surfaces that are formed on the radius of rotation of the moving contact; and sliding surfaces that are located at an angle to the first surfaces and slanted toward the center of rotation with respect to the line of action of a tangential force of torque at the points of contact with the guiding faces.

摘要： A breaker comprises a static contact, a moving contact, and an arc-extinguishing chamber. A contact surface of an electrical contact of the static contact and an electrical contact of the moving contact and a bottom plane of a base form an acute angle that is located in the first quadrant. The moving contact comprises a conducting rod having a projecting portion, and the electrical contact which is welded on an end surface of the projecting portion in a direction facing the electrical contact of the static contact. A bottom arc-ignition grid plate on the bottom of the arc-extinguishing chamber is arranged lower than the electrical contact of the static contact. A top arc-ignition grid plate on the top of the arc-extinguishing chamber is arranged higher than the maximum position of the electrical contact of the moving contact when the moving contact is opened.
