摘要： An object is to provide a DC power supply connector that can suppress occurrence of an arc discharge at DC power off with a small-scale configuration without reducing power efficiency during DC power supply and can reduce heat generation.The connector includes, on at least any of a positive-electrode-side electrode side and a negative-electrode-side electrode side, a movable contact piece (20c) that touches a first contact (25) in a state where a terminal (11) on a power receiving side has been inserted and to touch a second contact (24) in a state where the terminal has not been inserted, and a current limiting circuit (30) including a switching element (T1). The current limiting circuit (30) does not flow a current to the switching element (T1) in the case where the movable contact piece (20c) is touching the first contact (25), and flows a current to the terminal (11) through the movable contact piece (20c) until the movable contact piece (20c) is linked to the second contact (24) after separation from the first contact (25), and gradually decreases the flowing current.

摘要： A high voltage hybrid circuit-breaker has an arc circuit with a gas circuit-breaker connected in a series with a vacuum bulb. The housing is subdivided into a first compartment enclosed by an insulator for housing the primary contacts of the primary circuit and of the gas circuitbreaker and a second adjacent compartment (14) containing the vacuum bulb, defined by a conductive metallic shell. The movable arcing contact of the gas circuit-breaker is actuated with the movable primary contact by a primary control rod connected to a common mechanism, wherein the displacement of the movable arcing contact of the vacuum bulb is derived from the translational movement of the primary rod through an intermediate transmission lever received in the second compartment.

摘要： A circuit breaker for a distribution system includes a non-self-extinction type semiconductor switch, a current limiting element connected in series to the semiconductor switch for suppressing a fault current. The semiconductor switch and the current limiting element constitute a series circuit. A mechanical type high-speed switch is connected in parallel to the series circuit of the semiconductor switch and the current limiting element. Upon occurrence of a fault in the distribution system, an electric current flowing through the distribution system is commutated to the series circuit from the mechanical type high-speed switch.

摘要： A hybrid circuit interrupter is provided, having a set of contacts in a vacuum environment and another set of contacts in an insulating fluid, such as oil, or gas or the like, environment connected in series and disposed in one compact enclosure. During closing the contacts in the insulating liquid or gas are closed after the contacts in the vacuum have closed. During an opening operation the contacts in the vacuum chamber separate first and then the contacts in the chamber containing the insulating fluid or gas separate. Thus, the circuit is completed in the insulating liquid or gas environment and the circuit is opened in the vacuum environment. With the hybrid circuit interrupter fully opened two serially related gaps are provided in the circuit interrupter. One of the contacts in the chamber containing the insulating fluid or gas is rigidly mechanically connected to one of the contacts in the vacuum chamber. A single operating stroke opens or closes the hybrid circuit interrupter. The contacts used in the vacuum chamber can be constructed from material having low chopping characteristics so that high voltages are not induced in the electrical circuit during interruption. The contacts used in the chamber containing the insulating fluid, such as oil or gas, can be constructed from material having good non-welding characteristics so as not to weld upon interrupter closing and to be easily opened without the use of complicated and expensive weld breaking mechanisms.
