摘要： A protection device (100/300) includes a diode (102) having its forward direction in a normal power flow of a region of a DC collection system, a first switch (104) in parallel with the diode (102), a second switch (106) in series with the diode (102) and a control unit (108) for controlling the switches (104, 106). The first switch (104) can be opened so that current can flow through the diode (102) in the forward direction without the first switch (104) bypassing the diode (102), and closed if no current is flowing through the diode (102) in the forward direction and power is needed upstream of the diode (102). The second switch (106) can be closed so that current can flow through the diode (102) in the forward direction to an AC grid interface of the DC collection system, and opened if no current is flowing through the diode (102) in the forward direction due to a fault in a DC feeder ('Feeder 1', 'Feeder 2') to which the protection device (100/300) is coupled.

摘要： While transient current magnitudes at different locations within a DC distribution system themselves are not a reliable indicator of fault location, it is recognized herein that accumulating energy or pseudo energy values provides a reliable basis for tripping the protection element at a fault location. Thus, in one aspect of the teachings herein, pseudo energy values are accumulated independently during a fault condition, for each of one or more protected branch circuits and the protection element for each such branch circuit is tripped responsive to the accumulated pseudo energy values reaching a defined pseudo energy threshold. The pseudo energy thresholds are defined so that the protection element in the branch circuit where the fault is located will trip first.
摘要翻译：虽然在DC分配系统本身内的不同位置处的瞬态电流幅度不是故障定位的可靠指标，但是这里可以认识到，累积能量或伪能量值为故障位置处的保护元件跳闸提供了可靠的依据。因此，在这里的教导的一个方面，对于一个或多个受保护的分支电路中的每一个，在故障状态期间独立地累加伪能量值，并且每个这样的分支电路的保护元件响应于累积的伪能量值达到定义的伪能量阈值。定义伪能量阈值，使得故障所在的分支电路中的保护元件首先跳闸。

摘要： The camera of this invention has a film cassette compartment, a film spool (13), a film exposing area, and an interlock that prevents moving exposed film from the film cassette. With the camera, a film cassette (2) is loaded into the film cassette compartment. The film is then locaded by moving the film from the film cassette (2) compartment across the film exposing area and winding all but the first frame of film to be exposed around the film spool. After a picture taken, the exposed film is wound back into the film cassette and the next from of film to be exposed is moved into the film exposing area. The interlock prevents moving the exposed film out of the film exposing area. In an embodiment the interlock includes a lever that is engageable with the serrations of a film rewind wheel (22) to prevent movement of the film rewind wheel (22).
