摘要：该系统为保护电路防止过流的电气系统。它包括与载荷(8)并联的控制元件(6),电路中断元件(2)和旁路元件(4,17,19)。电路中断元件和旁路元件组成的并联组与由电载荷及控制元件组成的并联组采用串联方式连接。电路中断元件(2)有闭合和断开两种状态。当控制元件两端的电压为正常值时,控制元件(6)处于工作状态,而当电压降至或低于值VFAULT时,控制元件为非工作状态;将控制元件特别地和电路中断元件连接的目的是为了让电路中断元件在控制元件工作时闭合,而当控制元件不工作时断开。旁路元件包括第一旁路线路(17,4)和与之并联的第二旁路线路(19);它有启动和制动两种状态。在启动状态下,如电路中断元件断开,且电流INORMAL通过旁路元件时,则流经旁路元件的绝大部分电流从第一旁路线路通过,而且控制元件两端的电压大于VFAULT。在制动状态下,如果由于控制元件两端的电压降至或低于VFAULT而引起电路中断元件断开,则流经旁路元件的绝大部分电流将会从第二旁路线路通过,并且通过旁路元件的电流可使控制元件两端的电压值维持等于或小于VFAULT的电压值。

摘要： A solid-state zero current switching circuit breaker (100) is configured to interrupt current flow between a voltage input (104a, 104b) and a load (120). The solid-state zero current switching circuit breaker includes at least one resonant capacitor cell (102a, 102b) having an input configured to receive a source voltage (Vin POSITIVE, Vin NEGATIVE) and an output configured to deliver drive current to the load. The resonant capacitor cell is configured to selectively limit the drive current to the output based on a variable voltage. The solid- state zero current switching circuit breaker further includes at least one voltage clamping switch (118a, 118b) configured to detect a short-circuit fault or an overload condition. The voltage clamping switch adjusts the variable voltage in response to detecting the short- circuit fault condition or the overload condition such that the resonant capacitor cell limits the drive current.

摘要： Process for regulating a compressor with motor for a refrigerating system, where the temperature of the cooling site is regulated through an on-off motor mode if the temperature in the compressor exceeds an upper temperature threshold. In addition, the temperature of the cooling site is regulated through a continuous on mode of the motor as soon as the motor has cooled to a lower temperature threshold. The controller converts a variable corresponding to the cooling requirement of the cooling site into a switch signal for a valve, which results in clocked opening and closing of the valve, or uses a frequency converter, which controls the cooling liquid flow through the compressor by regulating the voltage and the frequency of the motor in that the frequency converter converts a variable corresponding to the cooling requirement of a cooling site into a voltage and a frequency for the motor.
